Title: Illumination optical device and projection type display device
Inventor: TANAKA TAKAAKI
IPC: G02B27/18
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To realize uniform illumination even when illuminating light on a light valve has a comparatively large f-number by providing a collimating lens changing condensed light into nearly parallel beams, plural lens array plates and a relay lens receiving the light and illuminating the light valve. SOLUTION: The lens array plates 35 and 36 of an illumination optical device are made small in size by the collimating lens 32 and the relay lens 39. Therefore, the lens of the lens array plates 35 and 36 is constituted of a microlens, the number of division of the lens array plates 35 and 36 is very increased, and the light emission area of a two-dimensional light source image formed on the pupil surface of a projection lens is made equal to the pupil area of the projection lens. Therefore, the f-number of the projection lens and the illuminating light is made large. Namely, the two-dimensional light source image formed on the pupil of the projection lens is formed to be fine and the efficient and uniform illumination is realized even when the f-number of the illuminating light on the light valve is >=6.

Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain a monitoring apparatus which reduces the constitution of a high-frequency module and of an analog circuit and which simplifies a circuit constitution when the bearing of an electronic scanning TACAN antenna is monitored. SOLUTION: When the bearing of an electronic scanning TACAN antenna is monitored, e.g. a change in the phase of variable bearing signals (15Hz, 135Hz) and a change in the phase of carrier waves are monitored. When the change in the phase of the variable gearing signals is monitored, pickup signals (pulse signals) from 36 array antennas are detected, and transmission levels of the repsective array antennas are detected by peak hold circuits 3. Then, their transmission level signals (peak level signals) are phase-corrected digitally so as to be synthesized, the waveform of the variable bearing signals is analyzed, and the change in the bearing (the phase) is monitored. When the change in the phase of the carrier waves is monitored, the pickup signals from the array antennas are mixed with a local signal, and the change in the phase is monitored by a phase detector 15.

Title: Magnetoresistance element
Inventor: TANABE KOJI
IPC: H01L43/08
Filed: 1987-12-21
Abstract: PURPOSE:To obtain a magnetoresistive effect of a high impedance and of a high degree by a method wherein a paste containing a two-dimensional graphite powder which has been plated with a precious metal and whose conductivity value is prescribed and a resin binder is coated and baked. CONSTITUTION:Silver is plated, by using a silver nitrate reduction method, on a nearly perfect graphite powder which has been manufactured by pyrolyzing a poly P-phenylene-1,3,4-oxadiazole film. The above silver-plated two-dimensional graphite powder, an isopropyl-etherealized phenol resin and terpineol are kneaded by using three poles; after that, this kneaded substance is coated on a glass epoxy laminated sheet by a screen-printing method; the substance is heated and hardened. If the ratio of a plating amount of a precious metal, the two-dimensional graphite powder and a resin binder is selected, it is possible to simply obtain a required impedance. When a conductivity value of the two-dimensional graphite is less than 5000S/cm, no magnetoresistive effect is obtained; the two-dimensional graphite of 5000 S/cm or more and less than 20000S/cm is desirable.

Title: Refrigeration cycle controller
Inventor: UESUGI NAOYOSHI
IPC: H02P6/06
Filed: 1992-12-03
Abstract: PURPOSE:To make protective action possible without stopping a compressor and also to prevent the breakdown of a semiconductor element surely. CONSTITUTION:A duty control circuit 15 outputs PWM control pulse signals, with preset duty, to a base driver 5, based on the signals from a duty setter 17, a cycle counter 18, and a clock generator 19. A duty limiting circuit 16 limits the duty of the PWM control signals within a certain range by outputting reset signals as limiting signals to a duty limiting circuit 15 at every cycle, when it detects that the current 1 flowing from an inverter circuit 4 to a converter circuit 2 reaches the level of an overcurrent, by the signal from a current detecting circuit 9. Hereby, since the current 1 decreases, the breakdown of the transistor inside an inverter circuit 4 can be prevented without stopping the operation of a compressor 6 and a compressor motor 7.

Title: Spring motor
Inventor: TKACZYK JOHN ERIC
IPC: H02K7/18
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To produce constant torque, regardless of the state of winding of the spring of a spring motor by wholly or linearly varying the width of the spring over the range from one end to the other end of the spring, to make spring force proportional to the width of the spring and the produced torque proportional to the product of spring force and radius. SOLUTION: A motor 10 is provided with a pair of drums or spools 14 and 16 which holds a flat tempered spring 18 forming a narrow metal strip. The spring 18 varies in width over the length of the spring 18, with its width being narrowest at the end of the spring 18 connected to the winding spool 16 and wider at its end connected to the crank-up spool 14. As a result, the outermost layer of the spring is narrowest, when the spring is reeled on the crank-up spool 14 and thereafter the inner layers are successively increased in width. Since the spring force is in proportion to the width, variations in width are equivalent to variations in force, and torque becomes constant, thus the speed of the generator generates a constant voltage.

Numerous grooves 10a are formed on the respective cushions 10 with equal intervals, and both lower ends of the module 2 are fitted into the respective opposite grooves 10a to support the module 2 in a standing state. Thus upper and lower cases may not shift in position from each other, thereby preventing the modules from shifting and being unfastened.

Abstract: PROBLEM TO BE SOLVED: To prevent hair from being pulled out from a bristle part at once and to hardly confine the heat of a hair drier by turning the bristle part to an elastic material and forming a notched part along the longitudinal direction of the bristle part. SOLUTION: A handle part 2 and the bristle part 3 are both constituted integrally of the elastic material such as plastic or wood and the two, for instance, notched parts 7 are formed in front and back along the longitudinal direction on the bristle part 3. Also, many through-holes 8 and 9 are provided on the outer peripheral surface of the handle part 2 and the bristle part 3. As a result, this entire roll brush 1 is full of elasticity, the roll brush 1 performs the role of a kind of suspension at the time of pulling the hair and a fear that the hair wound around the roll brush 1 is pulled out at once while blowing is eliminated.  Also, since hot air from the drier is circulated to the inside of the bristle part 3 through the notched parts 7 and the through-holes 9, the hot air is smoothly discharged, the hair is dried in a short time and the heat is not confined on the outer peripheral surface of the bristle part 3.
