Patent number: 5497170Abstract: A headup display apparatus consists of a projection optical system unit installed in the dashboard of a car and a reflection member on the windshield. The projection optical system unit contains an indicator and an off-axis reflective hologram which reflects display light of the indicator toward the windshield, which in turn reflects it toward the viewing point of a driver. As a result, the display is seen superimposed on the exterior view. When external light as from the sun enters the projection optical system unit traveling in a direction reverse to the path of the display light, the off-axis reflective hologram reflects the incident external light toward a direction different from that of the outgoing display light to minimize an abnormal illumination of the indicator surface which would otherwise render the display unrecognizable. Behind the hologram is installed a heat dissipating member that receives infrared rays that have transmitted the hologram in order to dissipate heat.Type: GrantFiled: December 5, 1994Date of Patent: March 5, 1996Assignees: Yazaki Corporation, Fujitsu LimitedInventors: Masayuki Kato, Hirokazu Aritake, Tsuyoshi Matsumoto, Junji Tomita, Fumio Yamagishi, Masato Nakashima, Masao Suzuki, Toshiaki Fujiwara, Masaya Sugita, Koichi Takoa

Patent number: 4961008Abstract: An electrical circuit is powered by a power supply. There is a first operating circuit which is always energized with electrical power from the power supply. The first operating circuit is operatively connected to a power reducing device. There is a second operating circuit which can, for example, operate the processing portion of a small appliance, such as an electronic calculator. The second operating circuit receives power from the power supply, but is not energized at all times. That is, the second operating circuit is energized with electrical power from the power supply when it is required to run the processing portion of the small appliance. When the small appliance is not run, the second operating circuit does not operate. There is, for an example, an ON/OFF switch on the electrical appliance, to turn the power supply on and off.Type: GrantFiled: December 28, 1988Date of Patent: October 2, 1990Inventors: Toshiaki Fujiwara, Chieji Katoh
