Title: Improved projection system
Inventor: KUHARETSUDO SARAIEDEIN
IPC: G09F9/35
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a rear projector by placing a polarizing filter and a planar mirror so that an outputted light beam is reflected by specified times. SOLUTION: The projector 1 being a liquid crystal projector emits a beforehand linearly polarized beam 2. Since, the beam 2 generates circularly polarized light, the light is faced to a small mirror, succeedingly to a 1/4 wavelength plate 9. The circularly polarized light transmits through a cho-lesteric filter 8 to be reflected by the planar mirror 7. The beam parting from the planar mirror 7 is abutted on the cholesteric filter 8. The light parting from the mirror is reflected from the mirror 7 to receive phase shift of different π. Thus, the reflection from the planar mirror converts the light polarized in a left turn to the light polarized in a right turn, and the light is transmitted to a screen by the cholesteric filter. In such a manner, triple reflection consisting of twice reflection from the planar mirror and once reflection from the cholesteric filter are performed.

Title: Fuel supply device for liquefied gas engine
Inventor: KUDO KAZUNORI
IPC: F02M21/02
Filed: 1991-11-15
Abstract: PURPOSE:To prevent fuel supply from becoming impossible due to a pressure drop by taking out liquefied fuel from a liquefied gas fuel storage container still in a liquid shape, and arranging a fuel passage to supply the fuel to a mixer so as to be heated by means of generated heat and so on of an engine in itself. CONSTITUTION:A fuel supply device 200 is composed of a fuel storage container 210, a liquefied fuel taking out means 600, a liquefied fuel heating means 700, a liquefied fuel passage 620, pressure governing valves 231 and 232 and a mixer 240. The fuel storage container 210 stores liquefied gas fuel 300 in coexistence of liquid phase and gaseous phase. The fuel taking out means 600 takes out the liquefied gas fuel 300 still in a liquid shape. The liquefied gas fuel 300 is vaporized while flowing in the liquefied fuel passage 620 arranged so as to be heated by means of generated heat of an engine in itself or a heating heater, and is flowed into the mixer 240 in a gaseous state. Thereby, since pressure in a liquefied fuel storage tank is not changed, fuel supply becomes hardly impossible due to a pressure drop in the fuel storage container 210.

Filed: 1989-12-16
Abstract: PURPOSE:To prevent accumulated noise of electrostatic charges from being discharged to an input part when the electrostatic charges are accumulated in an output part or a signal cable by emitting it to a signal cable where a reference potential is maintained using a diode. CONSTITUTION:Conductor patterns 11, 12 are formed in the surface of a substrate 10, a signal cord 13 connected with a signal pin 3b and a signal cord 16 composing a signal cable 4 are connected with the conductor pattern 11, and a reference cord 14 connected with a signal pin 3a and a reference cord 17 composing the signal cable 4 are connected with the conductor pattern 12. If negative electrostatic charges are accumulated in the signal cords 13, 16 to make the potential lower than a reference potential, these charges are emitted from the conductor patterns 11, 18 through a diode 20 and the conductor patterns 19, 12 to reference cords 14, 17, so the potential at the signal cords 13, 16 is maintained to be more than the reference potential. The electrostatic charges accumulated in output parts and signal cords in an IC or the like in a connected electronic device can thus be prevented from being discharged.

Title: Electrical circuit device
Inventor: YAMAGUCHI YOSHIHIRO
IPC: G11B33/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To simplify circuit adjustment in a manufacturing process and to reduce time. SOLUTION: When the substrate of an electrical circuit is constituted while it is divided into a main substrate 1 and a sub substrate 2 as in a magnetic recording/reproducing device, a power supply circuit 4 is located only in the main substrate 1. When a circuit is adjusted individually in the main substrate 1 and the sub substrate 2, a zener diode ZD for generating a reference voltage is required at each substrate. Since the main substrate 1 includes the power supply circuit 4, it can be adjusted individually. The sub substrate 2 that does not include a power supply circuit can be adjusted individually by amplifying the voltage of a reference voltage generation circuit 9 that includes the zener diode ZD by an external power supply circuit and supplying the amplified voltage (SW 5V) to the sub substrate 2. To prevent a plurality of reference voltages from existing when the main substrate 1 and the sub substrate 2 are electrically connected, only the reference voltage generation circuit 9 of one sub substrate exists to generate a reference voltage.
