20090290064 | AV System - AV content is input and output in an AV system. In the AV system, a plurality of AV devices process a signal of the content to reproduce the content. A source device broadcasts the content to each of the AV devices. In each of the AV devices, a reproduction unit receives the content broadcast by the source device and performs reproduction processing on the received content. A communication unit communicates reproduction processing time information with another AV device, the reproduction processing time information indicating a time required for the reproduction processing of the content. A delay unit delays a time to reproduce the content, such that the delay unit delays reproduction of the content in accordance with an AV device having a latest reproduction timing based on the reproduction processing time information. | 11-26-2009 |
20090316938 | LOUDSPEAKER APPARATUS AND SPEAKER SYSTEM - A loudspeaker apparatus includes a speaker array that has a plurality of speaker units which are arranged on a sound emitting surface of the speaker array, and emits sound beams on a plurality of channels, an angle sensing section that senses an angle change displaced from a previously set reference angle of the sound emitting surface, and an adjusting section that adjusts output angles of the sound beams in response to the angle change. | 12-24-2009 |

20080246360 | DIRECT CURRENT MOTOR - A slide surface of each segment defines a plane orthogonal to an axial direction of a direct current motor. A power supply brush is pressed against and contacted with the slide surface. The power supply brush includes a main brush and a sub-brush. The sub-brush has electrical resistance that is higher than that of the main brush. At least the main brush supplies an armature with power. The sub-brush is arranged more inward in the radial direction of the commutator than the main brush. | 10-09-2008 |
20090066179 | DIRECT CURRENT MOTOR - A slide surface of each segment defines a plane orthogonal to an axial direction of a direct current motor. A power supply brush is pressed against and contacted with the slide surface. The power supply brush includes a main brush and a sub-brush. The sub- brush has electrical resistance that is higher than that of the main brush. At least the main brush supplies an armature with power. The sub-brush is arranged more inward in the radial direction of the commutator than the main brush. | 03-12-2009 |
20090146525 | Commutator and direct current motor - A segment center line is defined for each segment. Each segment center line extends from the center in the circumferential direction of the radially outer end of the segment to the center in the circumferential direction of the radially inner end of the segment. A portion of each segment center line where there is the center in the circumferential direction of the radially inner end is inclined in a first circumferential direction relative to the radial line. A short-circuit member has a plurality of connection pieces. Each connection piece has an outer short-circuit end, an inner short-circuit end, and a coupling portion. Each coupling portion links the outer short-circuit end to the inner short-circuit end, which is shifted in a second circumferential direction from the outer short-circuit end. | 06-11-2009 |

20140106187 | SEALED BATTERY AND SAFETY VALVE - A sealed battery includes a return type safety valve. An annular projection that projects toward a valve body from a valve port is formed on a valve seat for the safety valve. The projection includes a first projection region and a second projection region that are defined by a shape of a tip of the projection and arranged in parallel in a circumferential direction of the valve port. The first projection region and second projection region have different curvature radii in a cross-section of the projection taken along an axial direction of the valve body. The pressure per unit area applied to the second projection region by the valve body is higher than the pressure per unit area applied to the first projection region by the valve body. | 04-17-2014 |

20100232610 | Acoustic Design Support Apparatus - In an acoustic design support apparatus, a speaker selection supporter selects a desired speaker as a candidate for use in a given space based on shape information representing a shape of the space. A speaker mounting angle optimizer calculates an optimal mounting direction of the selected speaker by selecting a mounting direction pattern which minimizes a degree of variation among sound pressure levels at a plurality of positions on a sound receiving surface defined in the space. An acoustic parameter calculator calculates a variety of acoustic parameters at sound receiving points within the space based on both of the shape information of the space and the optimal mounting direction of the speaker. | 09-16-2010 |

20080230307 | MUFFLE DUCT - A pipe is incorporated in an intake system and has a first hole for a noise in the intake system to be released therethrough. A cover covers the pipe for attenuating the noise and has a second hole coinciding with the first hole circumferentially of the pipe. | 09-25-2008 |
20090293832 | INTAKE DUCT - [Object] The object of the present invention is to provide an intake duct having waterproof function without increasing parts count. | 12-03-2009 |
20140190764 | AIR INTAKE DUCT - There is provided an air intake duct capable of fully achieving intake-air noise attenuation effect. The air intake duct has a duct wall section formed of resin in form of tube and configured to introduce external air into an internal combustion engine or alternate power supply system. The duct wall section is provided with a silencing member formed of a lamination of a surface layer formed of a non-woven fabric to which thermosetting resin is impregnated and a ventilation adjusting layer formed of an extendable paper material having a surface in which a plurality of concave and convex portions are formed, and the silencing member includes at least one pair of the surface layers on front and back surfaces of at least one pair of the ventilation adjusting layers, and an intermediate layer is formed between the paired ventilation adjusting layers, the intermediate layer being formed of a same material as that of the surface layer. | 07-10-2014 |
