  • Patent number: 10495217
    Abstract: An attachment structure for attaching a control component package unit to a transmission casing which accommodates a power transmitting mechanism of a vehicle and which is disposed in a drive-power-source compartment in a front section of the vehicle such that an axial direction of the power transmitting mechanism is parallel to a transverse direction of the vehicle. The control component package unit includes a container casing accommodating control components for controlling the vehicle. The attachment structure is configured to attach the control component package unit to a rear side part of an outer surface of the transmission casing, such that a straight line normal to the rear side part extends in a direction having a component of a rearward direction of the vehicle.

  • Patent number: 8854313
    Abstract: There is provided a technique which can reduce the entire thickness of a push-button switch while securing the brightness of the illumination and can increase the sensitivity and accuracy of a slide input. Use of a light guide sheet separating from a surface-type capacitance sensor is excluded, thereby being able to reduce the entire thickness of a sensor-integrated illuminated key sheet while a light guide sheet serves to secure the brightness of the illumination. A surface sheet is provided so as to contact the operation surface side of the light guide sheet as the substrate of the surface-type capacitance sensor. The distance between the operation surface of the surface sheet and the surface-type capacitance sensor can therefore decrease, which can enhance the sensitivity and accuracy of the slide input.

  • Patent number: 8827528
    Abstract: The present invention provides technology that can efficiently guide light to the interior of a key sheet and prevents light from leaking from the circumferences of key tops. A key sheet has a light-shielding dark print layer, on the rear surface of a base sheet, that is a cured body of a coating liquid that is not dissolve to the surface of the base sheet, and also has a smooth surface between the base sheet and the dark print layer. The invention can make light transmitting in the base sheet hard to enter the dark print layer so that the light can be efficiently guided in the base sheet, and also can prevent light from transmitting through the base sheet by blocking the light.

  • Publication number: 20120268379
    Abstract: To provide a technique which involves a key sheet integrally including a light guide sheet and having a plurality of illumination areas, the technique preventing light leakage from the boundary between the individual illumination areas and providing high durability against a repeated pressing operation. A mask layers cover the opening edges of slits of a light guide sheet on the operation surface side. The mask layers can prevent emission of light from the openings of the slits to the outside, the light having leaked from the end faces of the light guide sheet, and the end faces forming the slits. A front sheet and a back side cover can enhance the durability of a base sheet, the front sheet adhering to the light guide sheet so as to cover the slits.

  • Patent number: 8013262
    Abstract: Provided is a key sheet allowing reliable sliding operation input through accurate coordinate position detection and depressing operation input of satisfactory depression operability through clear click feel. Fixation layers are formed at positions under depressing operation portions, and there are no fixation layers in portions around the depressing operation portions but gaps are formed. With this construction, it is possible to suppress a depression operation load to a low level at a time of depressing input operation, and, when contact switches with click feel are depressed, the click feel can be easily transmitted. Further, a surface sheet has movable contact portions which enter the gaps at a time of sliding input operation and which are displaced so as to be capable of coming into contact with a sensor sheet. With this construction, it is possible to sense, in a stable manner, capacitance at an in-plane position of a sliding operation surface of the sensor sheet.

  • Patent number: 7168741
    Abstract: A first housing rotatably supports a steering shaft having an end portion coupled to a steering wheel. A second housing engages with the first housing via two impact energy absorbing rings separate from each other in the axial direction. The first housing and the second housing are relatively movable in the axial direction. One of the first housing and the second housing has first and second impact energy absorbing protrusions projected from positions between the impact energy absorbing rings separately in the axial direction so as to contact with the circumferential surface of the other of the first housing and the second housing. The impact energy absorbing protrusions therefore reduce the load applied to the impact energy absorbing rings in usual steering. Further, the impact energy absorbing rings reduce the load due to frictional resistance in impact energy absorption.
