20120073396 | MOTION GUIDE DEVICE AND SCREW DEVICE - Provided are a motion guide device and a screw device each having a cover for protecting the device against moisture, such as coolant, and powder dust. The motion guide device has a raceway member | 03-29-2012 |
20140301677 | MOTION GUIDE DEVICE - Provided is a motion guide device capable of suppressing generation of a gap between a first seal member and a second seal member, which are fixed to a moving block, and preventing foreign matters from entering the moving block, to thereby achieve a smooth motion of the moving block with respect to a track rail. The motion guide device includes: a track shaft having a rolling surface; a moving member freely movable along the track shaft; the first seal member that comes into sliding contact with a surface of the track shaft so as to close a gap between the track shaft and the moving member; and the second seal member that is provided along the rolling surface of the track shaft and closes the gap between the track shaft and the moving member. The second seal member includes: a fixing substrate locked to the moving member; and a seal portion that is firmly fixed to the fixing substrate along the rolling surface of the track shaft and includes a seal lip portion that comes into sliding contact with the surface of the track shaft and an extended seal portion that comes into close contact with the first seal member while being compressed by the first seal member under the state in which the first seal member is fixed to the moving member. | 10-09-2014 |
20160097421 | BALL JOINT - Provided is a ball joint capable of coupling a third mechanical element in a freely pivotable manner near a pivot center of a first mechanical element and a second mechanical element coupled to each other in a freely pivotable manner. The ball joint includes: a ball stud including: a shaft member configured to allow a first mechanical element to be coupled thereto; and a ball portion formed at a distal end of the shaft member; a holder including a fixing port ion configured to allow a second mechanical element to be coupled thereto, the holder being formed through casting with the ball portion being set as a core to cover a maximum diameter portion of the ball portion, the holder being configured to couple the first mechanical element and the second mechanical element in a freely pivotable manner with the ball portion defining a pivot center; and a pivot shaft that protrudes out of the holder in a direction of intersecting with the shaft member of the ball stud to define a second pivot center independently of the ball portion, and to serve as a coupling portion for a third mechanical element, the pivot shaft being integrated with the holder at the time of the casting of the holder. | 04-07-2016 |

20100281622 | LOW-VOC LEATHER - This object relates to a natural leather which is obtained by forming a coating film through the greasing step following re-tanning and dyeing and the drying step. The purpose of this object is to provide a natural leather, wherein the generation of free formaldehyde and acetaldehyde is inhibited, and a treating agent to be added in the greasing step for natural leather. A natural leather wherein formaldehyde and acetaldehyde generated by a tanning agent, a re-tanning agent, a dye and a greasing agent having been incorporated into a leather are confined in the leather with a treating agent to be added in the greasing step for natural leather which contains a hydrazide compound optionally together with sodium hydrogen sulfite to thereby inhibit or prevent the generation of formaldehyde and acetaldehyde, and an automobile interior part coated with this natural leather. | 11-11-2010 |
20110078862 | TOPCOAT - Provided is a natural leather having a novel coating layer which feels leathery. The coating film retains material properties such as strength and wearing resistance. When the user directly touches the natural leather, the coating layer present on the surface of the natural leather gives slick characteristics of natural leathers and smoothness. The natural leather has a coating film formed on a surface thereof, the coating film including: a color coat layer formed from a mixture of a hard component (10% modulus is more than 2.3 but no more than 3.0) and a soft component (10% modulus is more than 0.0 but no more than 1.0) of a two-component polyurethane resin; and a topcoat layer formed from a mixture of a medium component (resin having a 10% modulus of more than 1.0 but no more than 2.3) and a soft component (resin having a 10% modulus of more than 0.0 but no more than 1.0) of a two-component polyurethane resin. | 04-07-2011 |

20100325811 | Leather - A leather is obtained by a process where a re-tanning agent is used which is constituted by synthetic tannin, resin and aluminum. The synthetic tannin is constituted by (a) condensation product of aromatic sulfonic acid with formaldehyde, (b) methylene cyclic polymer of aromatic sulfonic acid with hydroxy aromatic compound, and (c) glyoxal. The resin is constituted by (a) acrylic acid, methacrylic acid, acrylic acid ester or methacrylic acid ester polymer(s), and copolymer(s) thereof, and (b) polycondensation product of melamine with formaldehyde. | 12-30-2010 |

20160115895 | CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - An object is to improve the combustion condition in an internal combustion engine equipped with a supercharger and performing diesel combustion using fuel having a relatively high self-ignition temperature in an operation state in which the engine load is increased or decreased. A control apparatus performs first injection during the compression stroke, causes spray guide combustion to occur, and starts to perform second injection at such a second injection time that combustion of injected fuel is started by flame generated by the spray guide combustion, thereby causing self-ignition and diffusion combustion of fuel to occur. During a response delay period in changing the boost pressure when changing the engine load of the internal combustion engine to a target engine load, the ratio of the quantity of fuel injected by the first injection to the total fuel injection quantity in one combustion cycle is made higher than the ratio of the quantity of fuel injected in the first injection to the total fuel injection quantity in one combustion cycle during the time when the engine load is equal to the target engine load and the actual boost pressure is equal to a target boost pressure corresponding to the target engine load. | 04-28-2016 |
