Title: Bias circuit for avalanche photodiode
Inventor: KOMURO TAMOTSU
IPC: H01L31/107
Filed: 1991-07-10
Abstract: PURPOSE:To prevent the signal-to-noise ratio deterioration by an avalanche current of an avalanche photodiode(APD) by limiting the cathode voltage of the APD to its breakdown voltage (reverse breakdown voltage) or below. CONSTITUTION:A diode (DD) 7 is connected via a resistor 8 from a voltage source 9 to the joint of a resistor 2 and the cathode of an APD 1. Letting VF be the DD 7 end voltage; IP1, the DD 7 current; IP0, the current from a power supply 6; IP, the APD 1 current; VF, the DD 7 forward voltage; and E1 the voltage of the voltage source 9, the formulas 1 through 3 are given. The cathode end voltage VA of APD 1 is expressed by the formula 4. When R<<R0, the formula 4 is approximated to the formula 5. Here, the formula 6 is obtained when E1<VA (IP1not equal to 0); and the formula 7 when E1>=VA (IP1=0). If a maximum voltage (E1+VF) has been set by a reverse breakdown voltage VBR, the APD 1 can be operated on a bias voltage on average higher than conventional without being operated in the breakdown region.

Title: Cooler for vehicle
Inventor: FURUKAWA TETSUO
IPC: B60H1/32
Filed: 1985-08-01
Abstract: PURPOSE:To reduce a rate of fuel consumption, by installing a heat exchanger for air cooling in a car room and an absorption type cooling device in a car body, respectively, while discharging heat in an absorbing part and a condensing part with the radiator installed in the front of a radiator, and constituting heat of the radiator so as to be led into a regenerating part. CONSTITUTION:A refrigerant circulates between an evaporator 14 and a heat exchanger 11 by a pump 19, and when it passes through a heat transmission pipe 14a of this evaporator 14, its head is absorbed, thus air cooling takes place. On the other hand, an evaporated ammonia enters the inside of an absorb er 15, absorbed in water, and condensed heat at that time is discharged out of a radiator 18 via hot water flowing inside a heat transmission pipe 15a of this absorber 15. And, an ammonia aqueous solution inside the absorber 15 is fed to a regenerator 16 and ammonia is evaporated and separated. The separated ammonia is fed to a condenser 17 and, after being condensed, it returns to the evaporator 14. With this constitution, a rate of fuel consumption in an engine is reducible.

Title: Electric heat insulator
Inventor: KIBI TAKAYUKI
IPC: A47J27/21
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To prevent a temperature detector from being stuck on a heating panel by the viscosity of liquid and to enable exact temperature control by integrally erecting an annular rib formed while being protruded upward at the peripheral edge part of a through hole on the heating panel, and positioning the upper surface part of the temperature detector higher than the upper end part of the annular rib. SOLUTION: When a liquid storage container 2 is placed on a heating panel 15, a bottom board 9 abuts on the top surface of a thermosensitive body 19 of a temperature detector 17, a coil spring 33 is compressed and the temperature detector moves down. When a heater 16 is electrified in such a state, the heating panel 15 is heated and water is boiled. When the water reaches a set temperature, it is sensed by the temperature detector 17 and the electrification is cut off. When the liquid is erroneously spilled on the heating panel 15 in this case, the liquid moues along the side surface of the thermosensitive body 19 and reaches a part in slidable contact with a through hole 20 on the heating panel 15 but the liquid flows down on the heating panel 15 by the annular rib and does not stay at the corner part between the thermosensitive body 19 and the heating panel 15.  Therefore, the liquid is prevented from entering the sliding part of the thermosensitive body 19.

Abstract: PURPOSE:To easily secure the desired acoustic image normal position by moving a pair of microphones for sound-collecting an acoustic signal, and varying a time difference and an acoustic pressure difference until the sound source direction is decided definitely. CONSTITUTION:The device is provided with a dummy head tuning device 9 for moving a dummy head 1 to the left and the right within a prescribed range as indicated with an arrow, and an acoustic signal is sound-collected from sound sources 10-12. As a result, an acoustic pressure level difference and a time difference are generated in the acoustic signals from the sound sources 10-12 which reach microphones 2, 3 to which the left and the right earlobes of the head 1 are attached. In such a state, the microphones 2, 3 are moved in the direction for approaching the sound sources 10-12 each other or in the direction for separating therefrom until the sound source direction of the acoustic signal, is decided definitely. In this case, a time difference and an acoustic pressure level difference of the acoustic signal of a transmission line from the sound sources 10-12 whose sound is collected are varied and recorded in a tape recorder 6. As a result, at the time of reproduction, the sound sources 10-12 can be subjected to normal position in the outside of the head, and the presence can be obtained. In such a way, the normal position of a desired acoustic image is secured easily without using a special means.
