| 20120101395 | DEVICE AND COMPUTER PROGRAM FOR ANALYZING BIOLOGICAL BODY STATE - A state change of a person is captured with timing closer to consciousness of the person. A frequency slope waveform of a time series signal of a pulse wave of a body of a person detected by an air pack is obtained by a frequency slope time-series analyzing and a computing device and a frequency fluctuation time-series waveform is obtained by a frequency fluctuation time-series analyzing and computing device. By comparing changes of two waveforms with each other in a waveform determining device, a state change of a person can be captured with timing closer to consciousness of the person. A sleep-onset point can be specified clearly based upon the case where a fluctuation waveform steep gradient portion indicating a steep gradient change emerges in the frequency fluctuation waveform, and amplitude and a base line position of the frequency fluctuation waveform or the frequency slope waveform are in predetermined ranges. Further, when a mean slope line of the fluctuation waveform steep gradient portion is approximately parallel to a mean slope line of the slope waveform steep gradient portion in the frequency slope waveform before emergence of the fluctuation waveform steep gradient portion, a sleepiness waveform is determined, so that a sleepiness state leading to sleep onset can be detected. | 04-26-2012 |
| 20120042994 | MANUFACTURING METHOD OF HIGH-STRENGTH AND HIGH-TOUGHNESS THIN STEEL AND HEAT TREATMENT APPARATUS - To provide a technique suitable for elevating strength and toughness of a thin low-carbon steel.

Further, by performing a heat treatment process involving rapid heating and rapid cooling multiple times, a duplex grain size structure of crystal grains with smaller grain diameters or a hard phase structure contained therein is obtained, so that a thin low-carbon steel with higher strength and higher toughness is obtained. | 02-23-2012 |
| 20120037279 | STRUCTURAL MATERIAL - A structural material is provided, the strength and toughness of which are well-balanced at a high level, suitable in particular for seat frames in automobiles, aircrafts and the like. Specifically disclosed is a structural material produced by integrally joining thin steel members in a part thereof and, after joining, thermally heating a part thereof so that the heat-treated part differs from the other parts in strength and toughness. Unlike a structural material, the strength of which as a whole has been uniformly improved by heat treatment, the above-described structural material consists of a part having a high strength and a part having low strength. Thus, a structural material, the strength and toughness of which are well-balanced at a high level can be obtained. Since the strength and toughness are well-balanced at a high level, the structural material is suitable particularly for seat frames in automobiles, aircrafts and the like. | 02-16-2012 |

| 20110251522 | BIOLOGICAL SIGNAL MEASURING DEVICE AND BIOLOGICAL STATE ANALYZING SYSTEM - A configuration is adopted where elastic members made of expanded rein beads and having a size covering air cushions are disposed between a skin member and the air cushions of a human body supporting device. By arranging a plurality of elastic members made of expanded rein beads and in a stacking manner, preferably, arranging two elastic members made of expanded resin beads, spring constants of the elastic members obtained from load-deflection characteristics when they are pressed to a deflection amount of 1 mm by a pressing plate with a diameter of 30 mm being higher than that of the air cushion and being different from each other, a biological signal can be transmitted to the air cushions without damping the biological signal, though the elastic members made of expanded rein beads and are provided. | 10-13-2011 |
| 20110169317 | SEAT - A seat has a configuration in which, in each side frame of a cushion frame, an inner frame and an outer frame which have flanges extending along peripheral edges thereof are faced to each other with a space therebetween at least partially, and the flanges are fixed by hemming process along the entire peripheral edges thereof. Since the entire peripheral edges are hemmed, the inner frame and the outer frame are securely fixed. Additionally, since the inner frame and the outer frame which are thin-plate-shaped are used, reduction in weight of each side frame can be achieved. Further, since the inner frame and the outer frame are faced to each other with a space therebetween at least partially, a compressive/tensile strength required as a side frame can be secured by inserting an expanded bead body into the space. | 07-14-2011 |
| 20110148175 | ELASTIC MEMBER MADE OF EXPANDED RESIN BEADS, LAMINATED ELASTIC STRUCTURAL BODY, AND SEAT STRUCTURE - To achieve weight reduction while providing elasticity sufficient in a cushioning member for a vehicle seat, an elastic member made of expanded resin beads includes an elastic covering material having stretching properties stuck to an outer face of an expanded bead body. Therefore, when the elastic member made of expanded resin beads is bent or compressed, the respective beads themselves configuring the expanded bead body are elastically deformed according to stretching or compressing of the elastic covering material, and since the elastic deformation is not such deformation that a gap between beads of the expanded bead body largely expands, a crack occurring between beads or permanent deformation does not occur so that bending or compressing becomes possible. Accordingly, the elastic member made of expanded resin beads is suitable as a cushioning member utilizing an elastic recovering force in a bending direction and a thickness direction thereof. | 06-23-2011 |

| 20100102608 | SEAT STRUCTURE - A seat structure applicable to both a normal posture and a comfortable posture, in which a sufficiently relaxed resting posture is available and an excellent comfort is obtained while seated. A cushion frame is supported by a rear link plate and a front link plate, set such that the rear link plate within its movable range has a displacement angle larger than a displacement angle of the front link plate, and an angle between a side frame portion of a base frame and the rear link plate becomes smaller than an angle between the side frame portion and the front link plate when the plates are rotated and moved to the forward-most positions. Consequently, a seating surface angle of the cushion frame increases as the rear link plate and the front link plate are rotated and moved forward. An inclination angle of a back frame itself does not vary but the seating surface angle of the cushion frame can be varied according to a movement of a person. | 04-29-2010 |
| 20100090514 | SEAT - A seat in which a cushioning member has a high following ability to a human body motion and which can efficiently damp a vibration inputted from the outside is provided. The seat is constituted to use a torsion bar | 04-15-2010 |

In a seat cushion of a vehicle seat, a first human body support portion having a center at a position corresponding to a substantially center between the pair of ischial tuberosities of a human body, and a second human body support portion corresponding to the vicinities of femoral bases of a human body and having a center at a position located forward at a horizontal distance of 100 mm along a longitudinally center line of the seat cushion from the first human body support portion are regarded respectively as spring elements, and static spring constants and dynamic spring constants thereof are set to a predetermined relationship. Thus, stability and vibration absorbency during static seating are improved. | 02-26-2009 |
