Abstract: A cooling apparatus (10) for a vehicle includes air-cooling first and second heat exchangers (12, 14) that are placed beside each other. A coolant flow-out portion (32) of the first heat exchanger (12) from which a first coolant which is a cooling target of the first heat exchanger (12) flows out and a coolant flow-out portion (36) of the second heat exchanger (14) from which a second coolant which is a cooling target of the second heat exchanger (14) flows out are placed at ends at opposite positions separated along a diagonal line on a parallel placement surface of the two heat exchangers (12, 14). A first cooling fan (20) is placed opposing the coolant flow-out portion (32) of the first heat exchanger (12), and a second cooling fan (22) is placed opposing the coolant flow-out portion (36) of the second heat exchanger (14). With this configuration, cooling performance of two air-cooling heat exchangers placed beside each other can be improved.

Abstract: In a touch panel device comprising a panel main body (4) including a grid array of transmission electrodes (2) and reception electrodes (3) and defining a touch surface (51), the transmission electrodes are connected to a transmission unit (5) for sequentially applying a drive signal to the transmission electrodes. A time constant element is connected to each transmission electrode via the corresponding lead wire to adjust an overall time constant of the transmission electrode, the time constant of each time constant element being selected to be greater as the length of the lead wire for the corresponding transmission electrode increases.

A track of the document, which moves through the document transport path (9), passes through a focal point (scan point) of the first image sensor (5) achieved when the first image sensor (5) is situated at a standby position.

Abstract: An image reader comprising a reading glass plate facing an optical scanning system and a platen roller provided opposite to the reading glass plate; both being grounded. It is combined with an automatic sheet feeder, which comprises a retardation roller containing torque limiters and corrugation rollers. An optimized combination of these rollers provides an ideal sheet transfer and avoids overlaid sheet transfer. Generation of paper dust and toner particles is minimized in the optimized sheet transfer. Furthermore, sticking of such dust and particles on the reading glass plate and the platen roller is prevented in an image reader of the present invention. Thus the image reader reads out high quality images without being affected by dispersed paper dust or toner particles, while overlaid transfer of mother document sheets is prevented in the sheet feeder.

Abstract: A rotating shaft coupling has a plurality of rotating-shaft-coupling-members. One of the rotating-shaft-coupling-members is multi-layered by a coupler connecting a shaft thereto, an elastic body and an inertia body which has a mass activating a torsion load in a rotating direction when the elastic body is rotating. A plurality of the rotating-shaft-coupling-members are assembled into the rotating shaft coupling. By this construction, transmission of the vibration from a motor side to a driven side can be effectively suppressed.
