Abstract: A projection display apparatus employing organic EL elements is presented that is light in weight, is small in size, and can be practically implemented. In particular, the apparatus suppresses light-emission performance degradation caused by generated heat, thereby extending useful life, stabilizing brightness, and securing continual maximum brightness. The apparatus comprises; liquid crystal panels 12R, 12G, and 12B; light emitting units 13R, 13G, and 13B, positioned at the back of the liquid crystal panels and provided with organic EL elements as light emitting layers; and cooling bodies 14R, 14G, and 14B, positioned at the back of the light emitting units, for dispersing the heat generated by the light emitting layers. The cooling bodies 14R, 14G, and 14B may, for example, be electronic cooling elements that employ the Peltier effect to absorb and radiate the generated heat. Alternatively, the cooling bodies may be configured as heat-dispersing fins that guide and disperse generated heat.

Abstract: In a body mount-type information display apparatus, a display unit (103) is attached to the head of a user, whereas a control circuit unit (105) is attached to the waist or the shoulder. The display unit enables a light beam from the outside to enter the eyes of the user as well as another light beam representing an image produced by the control circuit unit. The user can accordingly observe the image including required pieces of information for the work together with the outside view. This image may be menu-type information or an image in harmony with an object such as a building. In order to display the image in harmony with the object, the direction, the visual angle, and the size of the image are processed according to the positional relationship between the user and the object. Available input means include magnetic and optical pointing devices and a CCD camera for reading a bar code.

Abstract: In a waterdrop removing apparatus for a vehicle, a blower is attached to a part of high rigidity within a door body to reduce vibration and noise. Air discharged from the blower is guided to a door mirror by a nozzle to blow away waterdrops wetting a surface of the door mirror. The blower is attached to an attachment bracket which is fixed to a door hinge together with a front end wall of the door body interposed between the door hinge and the attachment bracket.

Abstract: A water droplet removing system for a vehicle provided with door mirror assemblies each having a door mirror base attached to a door body, and a mirror unit guides air discharged by a blower installed in a door body of the automobile to at least either the surface of a mirror included in the mirror unit or the outer surface of a side window to blow off water droplets wetting the surface of the mirror or the outer surface of the side window. The blower is installed in a dead space defined in front of a guide rail placed in the door body to guide the front edge of the side window for vertical movement in the door body so that the interference between the blower and parts arranged within the door body including the side window can be avoided.

Abstract: A head-mounted display device for enlarging an image formed by an image display element as a virtual image. The head-mounted display device according to this invention comprises a virtual image forming optical system (3) including an image display element (9) and a lens (11) for enlarging an image formed by the image display element (9); a device main body (1) that houses the image forming optical means (3); and a switching means mounted in the device main body (1) for holding the virtual image forming optical system (3) in such a way that the system (3) can be moved in the direction of the width of the eye and placing the virtual image forming optical system (3) in front of one of the user's eyes. The image display element (9) and the lens (11) are disposed so that the optical axis of the virtual image forming optical system (3) approximately aligns with the user's line of sight taken while he or she is looking horizontally.

Abstract: A projection-type color display device. The display device includes a light source which provides light and a color separation member which receives the light and which separates the received light into the different colors of red, blue and green light. A light valve device receives the red, blue and green light and modulates the light to produce images. A color synthesis cube prism synthesizes the three monochromatic lights modulated by the light valve. A projection lens system projects the synthesized image onto a screen for viewing.

Abstract: An improved circuit for providing a fixed reference voltage with a minimum consumption of power is provided. The circuit includes a fixed voltage element adapted to be referenced to a fixed voltage. A charge storage element is coupled in series with a uni-directional current gating element, the series coupled charge storage element and uni-directional current gating element being coupled in parallel with the fixed voltage element. A voltage supply intermittently applies a referencing voltage across the fixed voltage element to thereby intermittently charge the charge storage element to a fixed reference voltage for at least a predetermined period of time.

Abstract: A brushless motor drive circuit including at least one hall effect element and a drive transistor circuit adapted to produce a signal to energize at least two drive coils, which coils operate to drive the brushless motor. The amplitude of the signal applied to said drive coils is determined by the current supplied to the drive transistor circuit. A control circuit is provided for controlling said supplied current in response to the speed of the motor. The control circuit includes a single transistor coupled to said drive transistor circuit, the series connection of a constant voltage produced by a voltage limiting device and a voltage representative of motor speed being coupled to the base of the transistor to bias the control transistor to maintain a constant motor speed.
