Title: Semiconductor device
Inventor: TSUJI SEIICHI
IPC: H01L23/38
Filed: 1990-01-18
Abstract: PURPOSE:To positively cool a semiconductor operation part without being concerned about a complicated package structure and about the dissipation of heat by a method wherein the semiconductor operation part is cooled by using a thermoelectric cooling structure which has been installed on the rear or in the intermediate layer of a semiconductor device. CONSTITUTION:Two different kinds of semiconductors 3, 4 are connected, via an electrode 2, in a pi shape to the rear or the intermediate layer of a semiconductor device. By this structure, a direct current can be applied to the two kinds of semiconductors 3, 4 through two electrodes 5, 6. Consequently, when the direct current is made to flow to the two different kinds of semiconductors connected to the common electrode 2 in the pi shape, the side of the common electrode can be cooled by the Seebeck effect. By utilizing this cooling mechanism, an operation part 1 of a semiconductor main body is cooled. Thereby, since the cooling mechanism part can be constituted so as to come into contact with the operation part of the semiconductor main body, the operation part can be cooled effectively.

Title: Pressure sensor
Inventor: HINATSU JIYUNJI
IPC: G01L11/00
Filed: 1985-01-25
Abstract: PURPOSE:To detect the pressures at two places by one piece of a sensor and to measure these pressure difference by impressing external pressure from two directions which are at right angles each other and by transmitting a polarized light through two pieces of photoelastic element that the optical path is arranged on the same axis. CONSTITUTION:When the first pressure is applied on a diaphragm 6a from the external part the same pressure is impressed on the first photoelastic element 5a. When the second pressure is applied on the second diaphragm 6b of the opening part of the side face of a case 12 the same pressure is impressed on the second photoelastic element 5b. The first pressure is impressed on the element 5a, then a phase difference is caused with the double refraction of the linear polarized light being made incident, making a plane polarized light. When this plane polarized light is made incident on the element 5b on which the second pressure is impressed, the double refraction is again caused, making the plane polarized light having the phase difference corresponding to the double refraction. Namely the light at the outlet port of the element 5b becomes two plane polarized light rays having the characteristics of the double refraction and phase difference corresponding to the difference of the first and second pressures. It is converted into electrical signal at the inside of a light receiver 11.

Abstract: PURPOSE:To prevent the left-and-right inclination of a rack, permit the movement of the rack with comparatively small force and avoid the collision of frames against each other as well as contact between the frame and the bottom of a refrigerator by a method wherein the rack is moved up-and-down by rotating spur gears on both left and right ends simultaneously by a driving device, rotating a gear shaft or the spur gears, While a frame is provided with a collision preventing stopper at the lower part of the front surface of the same. CONSTITUTION:When a dial 6a is turned, a dial shaft 7 and a driving gear 8 are turned. Accordingly, a transmission gear 9, meshed with the driving gear 8, is turned whereby a gear shaft 4 and spur gears 5 at both sides are turned. In this case, the spur gears 5 are moved while being meshed with a rack 14b at the front side of a sliding groove 14a through the gear shaft 4, however, left and right spur, gears 5 are fixed to the gear shaft 4 and are turned with the same rotation whereby a frame 2 or a rack 1 is moved up-and-down symmetrically and a positional deviation between the left height and the right height of the rack 1 will never be generated. On the other hand, the frame is prevented from contacting with the bottom of a refrigerator by collision preventing stoppers 2a', 2b' provided at the lower part of the front surface of the frame 2 even when the frame is descended excessively.

Title: Radio receiver for microwave radiometer
Inventor: MACHINO YOSHIATSU
IPC: G01N22/00
Filed: 1980-02-01
Abstract: PURPOSE:To improve the resolving power of an A/D converter by applying automatic gain control (AGC) to the A/D converter during observing in a radio receiver of Dicke type. CONSTITUTION:The electromagnetic wave received in an antenna 1 passes a switch 2 and passes a comparing noise source 3 and a Dicke switch 4 which makes change- over operation at fixed intervals. Thence, the signal is converted of frequency and amplified in an RF/IF circuit 5, is passed through a square-law detector 6 and is adjusted of level at a step attenuator 7. The attenuator 7 forms an AGC circuit by feeding back the output of an A/D converter 8. The input signal is detected by the signal from an oscillator 10 by a synchronous detector 9. Next, it goes through an integrating circuit 11 and is outputted from the A/D converter 8 after it has been A/D converted. A low temp. noise source 12 and high-temp. noise source 13 for calibration are changed over by a change-over switch 14, and at the calibrating with the switch 2, either of the two noise sources for calibration is connected to a radio receiver. After the calibration is completed, the AGC circuit is closed and the AGC circuit is so operated that the input to the A/D converter is always the maximum input voltage even during the observation of antenna input noise.

Title: Gauge for degree of discomfort caused by air pressure change
Inventor: AKUTSU KATSUNORI
IPC: A61B5/03
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a gauge for the degree of discomfort caused by air pressure change which has a mechanism capable of simulating the construction of human ears more faithfully compared to a conventional gauge of this type and at the same time, counts the degree of discomfort quantitatively and has a good recording function. SOLUTION: This gauge for the degree of discomfort under an air pressure change generates an air pressure signal by detecting an outer pressure with a pressure sensor 1, and simulates a pressure in the internal ear by integrating a difference between the outer pressure and the inner pressure of the internal ear using an integrating circuit 5, after amplifying the air pressure signal through an input amplifier 3. In this case, a time constant used for integrating the pressure difference varies between the case of boosting the pressure and the case of lowering the pressure. Next, an operation to subtract the inner pressure of the internal ear from the outer pressure is performed using a subtraction circuit 7.  An output from the subtraction circuit 7 is displayed on a display device 15 after passing through an absolute value circuit 9, a primary delayed dynamic property circuit 11 (momentary fluctuations are dulled) and a logarithmic conversion circuit 13.
