Title: Projection video display device
Inventor: MIHARA HISAYUKI
IPC: G03B33/12
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To make a device possible to be miniaturized, to reduce the cost reduction and to improve a color separation characteristic and utilizing efficiency of light by reducing a load imposed on a projection lens with simple constitution. SOLUTION: Three sheets of dichroic mirrors 13a-13c are arranged between a pin hole plate 12 as a polarizing plate and a liquid crystal panel 6 so as to become a 45 deg. angle for nearly parallel light main light beam of an optional wavelength range from the pin hole plate 12 and respectively in parallel to each other at a prescribed distance equal interval. These dichroic mirrors 13a-13c color-separate the emitted parallel light to equal angular light by transmitting or reflecting it in the optional wavelength range. In such a manner, color-separated respective color light are emitted to respective corresponding liquid crystal cells (opening parts) 6a-6c of the liquid crystal panel 6.  Then, the utilizing efficiency of light equal to color-separation by conventional angular control is obtained and a maximum divergent angle after passing through the liquid crystal panel is made small to reduce the load imposed on the projection lens and as a result, to contribute the cost reduction and the miniaturization of the device.

Title: Control valve
Inventor: SAKO MITSUSATO
IPC: F16K31/02
Filed: 1988-05-25
Abstract: PURPOSE:To enable fluid to be completely interrupted at the time of entire closing as well as to make a device compact by rotating a rotating disc piled upon a stationary disc by means of the stator of a piezo-electric motor so as to enable the openings of both of the discs be communicated with each other, and thereby sealing both of the discs with magnetic fluid. CONSTITUTION:When a rotating disc 6 is rotated against a stationary disc 5 with stator 7 of a piez-electric motor driven, an opening area communicating the opening 5a of the stationary disc 5 with the opening 6a of the rotating disc 6 is changed so that the flow-rate or the pressure of fluid flowing within a valve main body 1 can be controlled. And when the openings 5a and 6a of the stationary disc 5 and the rotationary disc 6 are uncommunicated with each other, a valve is entirely closed. In this case, since there exists magnetic fluid 15 around the opening 5a of the stationary disc 5, even if there is a gap more or less between the stationary disc 5 and the rotary disc 6, the gap can be sealed by the magnetic fluid 15. No fluid leak therefore develops, thereby enabling the fluid to be completely interrupted.

IPC: H03F3/34
Filed: 1982-07-23
Abstract: PURPOSE:To eliminate the influence of an electrostatic capacity and to realize a high-speed response characteristic, by interposing a non-inverted buffer amplifier between the other input terminal and the first input terminal of an operational amplifier. CONSTITUTION:A non-inverted buffer amplifier 8 is interposed between a minus input terminal 1a of an operational amplifier 1 and an input terminal 7, and its gain is set to about 1. The terminal 1a is connected to the side of an input terminal 8a of the amplifier 8, and the terminal 7 is connected to an output terminal 8b of the amplifier 8. A converted voltage output is obtained from between an output voltage terminal 5 connected to an output terminal 1c of the amplifier 1 and an output voltage terminal 6 connected to the earth or between the terminal 5 and another output voltage terminal 7' connected to the output terminal 8b of the amplifier 8. Therefore, output terminals 8a and 8b have the same potential independently of a current value supplied from a current source 9 to be converted and its variance, and the circuit between input terminals 3 and 7 is held in the short-circuited state. Consequently, a high-speed response is realized without the influence of the electrostatic capacity.

IPC: F24F13/30
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To hardly mix together suction air and discharge air and to improve conduction ability of air, by partitioning the interior of a box into a suction passage and a discharge passage by a partition structure with a fan forming a boundary, in a circulator formed that a suction port and a discharge port are formed and a box containing a fan is mounted on a ceiling. SOLUTION: When a fan 10 is rotated, indoor air is sucked through a suction port 28 and discharged in a room from a discharge port 26 through a route consisting of a suction passage 32, a fan 10, and a discharge passage 34. Namely, air present at the vicinity of a ceiling is sucked through the suction port 28 and discharged from the discharge port 26 toward right below. Accordingly, indoor air is effectively circulated and attributed to an indoor temperature. Further, since the suction passage 32 and the discharge passage 34 are partitioned from each other in a box 12 by a cylinder body 36, a series of flow passages is formed and air smoothly flows. Besides, since the discharge port 26 is formed in a central part, a discharge force is reinforced and the degree of mixture with intake air is decreased.
