  • Patent number: 6082288
    Abstract: A pair of resilient clamps hold L-shaped terminals which extend from a self-luminescent indicator. An insulator disk holds a flexible conductive coil member and has slots which accommodate an end of the coil member and the resilient clamps in compressive state so that resilient force of the resilient clamps provide stable electric connection between the L-shaped terminals and the end of the coil member automatically when the clamp members are inserted into the slots. A pair of stationary catch members hold the other end of the coil member and connect it to an electric source. The connection between the other end of the coil member and the catch members is carried by hot punching to form thermo-compression bonding layer. The connecting portions of the catch members and the coil member are plated with tin or solder beforehand for this purpose.

  • Patent number: 6025820
    Abstract: An instrument panel having analog gauges with pointers illuminated independently of the light source illuminating the scale indicia. Light is transmitted into the pointer via a facet having an inclined reflective surface through which a gauge motor output shaft passes. The facet may be integrally formed in the light distribution layer which illuminates the scale indicia or a separate discreet component. A novel telltale used in conjunction with an instrument panel having a light distribution layer is also provided which illuminates the telltale indicia by passing light through the light distribution layer without affecting the illumination of other indicia in the graphic layer. Method of manufacturing analog gauges as well as method for using an analog gauge to transmit information to a viewer.

  • Patent number: 5884577
    Abstract: A direction gauge enables easy recognition of an indicated direction by constructing an arrow-shaped indication segment made up of an unshared segment and a pair of adjacent shared segments. The combination of shared and unshared segments forms an indication segment having a sharp outward-directed tip and a blunt base. The sharp outward directed tip is the outer end of the unshared segment. The blunt base is a combination of the inner end of the unshared segment together with the two adjacent shared segments. The indication segment provides a good indication of direction even if the indicia on the remainder of the display cannot be seen because of darkness.

  • Patent number: 5697322
    Abstract: An analog display includes a dial and a movable EL pointer positioned adjacent the dial for indicating a measured value. The pointer is an elongated EL lamp having a conductive pin extending through one end of the lamp and about which the lamp pivots. The pin is mechanically secured to the lamp and is electrically connected to the front electrode of the lamp. A hole larger than cross-sectional diameter of the pin is formed in the rear electrode and in the phosphor layer to prevent the pin from shorting the front electrode to the rear electrode. A conductive spring rests on the pin to provide electrical power to the front electrode. Power is supplied to the rear electrode either through a conductive ferrule attached to the rear electrode or through a resilient wiper. The wiper can be attached to the pointer or to the face of the dial. For plural pointers, concentric conductive pins are used with a sliding contact for the rear electrodes.

  • Patent number: 5406303
    Abstract: An instrument display method and system for use in a passenger vehicle has a number of advantageous features including particularly novel, compact, inexpensive and inherently stable electric motors. A first motor includes a rotor assembly having a shaft and a cylindrical magnet which is positioned about a stator assembly to rotate thereabout. The shaft extends through a stator of the stator assembly, a vacuum fluorescent display (VFD), and an indicia bearing layer. A mask such as a needle pointer is secured to the shaft of the rotor assembly at the indicia bearing layer to convey the value of instrument data to the passenger. A light emitting panel receives light from the VFD and transmits the light to other positions along the display system where other substantially identical electric motors move their needle pointers to likewise convey additional data to the passenger. The first motor is surface mounted directly on the back of the VFD which has electrical conductors formed therein.

    Abstract: A gauge for a vehicle has a spontaneous light-emission type pointer with a built-in light-emitting device. The pointer is fixed to a pointer shaft rotatably driven in accordance with a measured value. A solid circuit member for supporting a light-emitting device and for coupling the light-emitting device to the pointer shaft is fixed to the pointer. The solid circuit member has a first plated conductive layer for electrically connecting one of the terminals of the light-emitting device to the pointer shaft, and a second plated conductive layer for electrically connecting the other of the terminals to a spring abutment fixed to the pointer shaft in an insulating fashion. The solid circuit member is connected to a power source for lighting the light-emitting device. Consequently, a number of parts required for supplying power to the light-emitting diode can be reduced.
