Title: Production of hologram
Inventor: KATO TETSUYA
IPC: G06K7/12
Filed: 1992-06-05
Abstract: PURPOSE:To omit the operation to remove mirrors and to necessitate one piece of special filter so as to decrease the laborious operations to adjust this filter and to omit a baffle, thereby lessening the loss of energy. CONSTITUTION:A copy hologram dry plate 2 is superposed on a master hologram 1 photographed by object light and reference light which both are diverting light. The laser beam from an argon laser oscillator 3 is diverged by the special filter 4. This divergent light is changed to collimated beams of light by a convex lens 5 and these collimated beams of light collimated beams of light bent in such a manner are bent by a second flat plate mirror 7 and the rest are bent by a third flat plate mirror 3. Both of the upper side and lower side of the master hologram 1 are irradiated with these collimated beams of light. The recording image of the master hologram 1 is copied on the copy hologram dry plate 2 in such a manner, by which the hologram for reading bar codes is produced.

Title: Polarized beam splitter
Inventor: KIMURA YASUO
IPC: G02B5/30
Filed: 1988-06-15
Abstract: PURPOSE:To contrive the reduction of cost and the improvement of mass productivity by disposing a metallic surface relief grating having a specific relation with the wavelength lambda of incident light to such a position where approximately the Bragg angle of the grating is attained with respect to the incident light. CONSTITUTION:The metallic surface relief grating 9 having the pitch nearly equal to the wavelength lambda of the incident light and having the grating groove depth (d) of 0.75lambda<d<lambda is so disposed that the light enters the grating at the angle approximate to the Bragg angle of the grating. The reason for averting the coincidence of the incident angle with the Bragg angle is to separate the 1st order diffracted light and the incident light. The zero order diffracted light 11 and the 1st order diffracted light 12 are the linearly polarized light intersecting orthogonally with each other of the incident light is circularly polarized light 10. For example, gold 14 of a suitable thickness is deposited by evaporation in a substrate 13 and a grating pattern is formed thereon by a photoprocess; thereafter, the gold is etched by a wet or dry etching method with the photoresist as a mask to form the gold surface relief grating 15. The material cost and the man-hours of production are drastically reduced in this way and the polarized beam splitter is obtd. inexpensively with the high productivity.

Patent JP-S6038633-A (JP)
Title: Pressure sensor
Inventor: MATSUMURA EIICHI
IPC: G01L1/22
Filed: 1983-08-10
Abstract: PURPOSE:To minimize temperature change in a pressure sensor by generating heat from an output transistor depending on a comparison output with the reference temperature detecting the temperature of a pellet of a silicon diaphragm. CONSTITUTION:The temperature in a pellet Pe of a silicon diaphragm is detected with diodes D1 and D2. As the temperature in the Pe falls, the voltages across the D1 and D2 rise. A reference voltage by division of a constant voltage source VA with resistance R7 and R8 is applied to the base of a transistor Q2 composing a comparator. As the base voltage of a transistor Q1 falls below the reference voltage according to the voltage change in the D1 and D2, the transistor Q4 is driven to drive transistors Q5-Qn. With the generation of heat from the Q5-Qn, the temperature in the Pe rises to reduce the voltages across the D1 and D2 and with a rise in the base potential of the Q1, the currents of the Q4 and Q5-Qn decrease. Thus, the temperature in the Pe is stabilized to the temperature determined by the reference voltage.

Patent JP-H09331017-A (JP)
Title: Overcurrent protector
Inventor: FUKAZAWA HIDEKI
IPC: H01L33/00
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide an overcurrent protector exhibiting a good overcurrent detection sensitivity regardless of the temperature while suppressing power consumption. SOLUTION: Power is fed through a protector 70 to an emission element section 21 being driven through a driver 20. A voltage drop across an overcurrent detection resistor 704 in the protector 70 is amplified through an amplifier comprising transistors 707, 708. When an overcurrent flows through the emission element section 21 to cause voltage drop at a joint PA, the transistor 707 operates in unsaturated state to cause voltage drop at a joint PB. Since the voltage at the joint PB is divided and fed to the base of the transistor 707, a transistor 702 is controlled to reduce voltage drop across the resistor 704 thus reducing the current. Consequently, the light emission power of the emission element section 21 can be prevented from exceeding over a desired range.  Furthermore, since the current is limited by means of a differential amplifier using the voltages at the joints PA, PB, a good overcurrent detection sensitivity can be attained regardless of the temperature while suppressing power consumption of the resistor 704.

Title: Liquid crystal display device
Inventor: MATSU FUJIO
IPC: G09G3/18
Filed: 1991-06-18
Abstract: PURPOSE:To automatically prevent a fact that a DC voltage is applied at the time of turning on a power source by generating a signal for inhibiting a fact that a driving voltage is applied to a liquid crystal panel until a prescribed time elapses, after the power source is turned on. CONSTITUTION:After the power source is turned on, a capacitor 2 is charged through a resistance 1, therefore, the potential of a positive electrode side of the capacitor rises gradually to an H level from an L level. When this potential is inputted to a Schumitt trigger inverter 4, an output of a Schumitt trigger inverter 5 becomes a signal 1NH converted to an H level from an L level with a delay of a prescribed period, after the power source is turned on. This 1NH is inputted to a base of a transistor 6 for controlling an output of a liquid crystal driving voltage, and controls turn-on/turn-off of the liquid crystal driving voltage. In this case, a period until the liquid crystal driving voltage is turned on after the power source is tuned on depends on a time constant determined by the resistance 1 and the capacitor 2, therefore, the adjustment can be executed.

Title: Cooler for riding room of automobile
Inventor: KAJIWARA YASUO
IPC: B60H1/00
Filed: 1982-08-24
Abstract: PURPOSE:To improve comfortableness, by heightening the rotational frequency of an indoor blower when a relatively high temperature is set during cooling, to increase the quantity of sent air which would conventionally decrease. CONSTITUTION:When the quantity of air passing through a hot water heater 17 has exceeded a prescribed value, a relay 11 is put into operation by a damper position detecting switch 13 to short-circuit a speed control resistor 8 to heighten the terminal voltage of an indoor blower motor 2. Consequently, the rotational frequency of the motor is increased to augment the quantity of air to compensate for the loss due to the passing through the hot water heater 17. According to this constitution, the time that it takes to reach a desired cooling temperature is not lengthened and uncomfortableness is prevented from being caused by the decrease in the quantity of air.

Title: Operation control method for cooling box
Inventor: SEKINE RYOJI
IPC: F25D11/00
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the temperature rise of foods by delaying the operation of a fan even if the temperature of a chiller is higher than a set level immediately after a defrost operation so that warm air does not flow into the compartment thereby suppressing the inner temperature rise after the defrost operation. SOLUTION: Operation of chiller fans 11a, 11b, 11c and compressors 12a, 12b is stopped simultaneously when a defrost operation is started so that heat for defrosting chillers 10a, 10b does not flow into a storage compartment. Consequently, the temperature rise in the storage compartment can be suppressed during defrost operation. After a switching is made from defrost operation to cold insulating operation, the chiller fans 11a, 11b, 11c begin to operate when the temperature of the chillers 10a, 10b drops below a set level through operation of the compressors 12a, 12b so that excess heat of defrost operation does not flow into the storage compartment.  Since warm air can be prevented from flowing into the compartment by delaying operation of the chiller fans 11a, 11b, 11c until the temperature of the chillers 10a, 10b drops after cooling operation, temperature rise of foods can be prevented.
