Title: Temperature measuring apparatus
Inventor: SAGAWA MASATO
IPC: F16K31/66
Filed: 1978-02-22
Abstract: PURPOSE: To perform detection of temperature rapidly and accurately by using the ferromagnetic material whose magnetization easy axis direction reversibly changes with temperature.  
     CONSTITUTION: When a material 2 whose magnetization easy axis direction changes with temperature is disposed in a freely turnable state in the magnetic field formed by a magnet 1, the magnetization easy axis direction faces the direction parallel to the magnetic field. Since the magnetization easy axis direction changes reversibly whe temperature changes, the temperature of that time may be measured by reading the relative angle of the magnet 1 and the material 2.

Filed: 1986-01-30
Abstract: PURPOSE:To attain a 1-3 decoder circuit with a simple constitution by using an input circuit having a different threshold level. CONSTITUTION:The threshold level of an inverter 1 is set higher than the threshold level of an inverter 2.

Filed: 1990-01-30
Abstract: PURPOSE:To form fine patterns having a good shape and high dimensional accuracy by using a resin which copolymerized a component having high heat resistance together with a functional group which is soluble in alkalis in an acid atmosphere as a pattern forming material. CONSTITUTION:A pattern forming material film 2 contg. the resin having the functional group which is soluble in the alkalis in the acid atmosphere and the component having the heat resistance, a photosensitive compd. which generates an acid by exposing, and a solvent which can dissolve the resin and compd. is formed on a substrate 1. The material film 2 is subjected to selective exposing with far UV rays, heat treatment and developing to form the material film patterns. Since the heat resistance of the resin itself is high, there is no softening of the resin at the time of the heat treatment and a large difference in solubility in an alkaline developing soln. arises between the exposed parts and the unexposed parts; in addition, the resin in the unexposed parts does not soften at the time of the heat treatment. The pattern 2a, 2a' of a positive type having a good contrast and the high dimensional accuracy are formed in this way.

Title: Missing signal compensator
Inventor: HARIHARA SHIYUUGOROU
IPC: H04N5/94
Filed: 1978-02-22
Abstract: PURPOSE: To obtain reproduced images of less noises for the signal missing period by changing over the terminal of a changeoever circuit from normally contact to normally break and outputting the video signal from the common terminal only during the missing period of the video signal.  
     CONSTITUTION: The output of a head amplifier 1 is directly connected to a limiter 6 and is made to the video signal by a demodulating circuit 7, after which it is connected to the normally contact terminal of a changeoever circuit 8 and the output from the common terminal is sent to an output amplifier 9 and is at the same time synthesized with a high frequency signal in a non-linear type amplifier 10. The signal is then delayed with a delay circuit 11 of one horizontal period by an ultrasonic delay line and this delayed signal is separated to the high frequency signal and video signal by a non-linear amplifier 12. The video signal is connected to the normally break terminal of the circuit 8. When in this state a detection circuit 3 detects drop-out, the circuit 8 is changed over to the normally break terminal side only for the detection period and the video signal is outputted from the common terminal, thus the drop-out is compensated. Thereby, the good reproduced images of less noises may be obtained even in the drop-out period.

Abstract: PURPOSE:To make a memory element operate stably with no latch-up phenomenon even when combined with a peripheral device such as a C-MOSIC circuit by composing the memory element of a P-channel FET of lamination gate structure and by allowing it to operate under fixed conditions. CONSTITUTION:In N<->-type Si substrate 1, P<+>-type drain region 2a and P<+>-type source region 2b are formed by diffusion, and shallow N-type region 9 touching region 2a is also formed by diffusion, Next, 1st polycrystal Si gate layer 4 on region 9 and SiO2 film 3 including 2nd poly-crystal Si gate layer 8 expanding onto region 2b are both adhered over the entire surface and after an opening is made, Al electrodes 5 are fitted to regions 2a and 2b, and gate layer 8. In this way, since region 9 of higher impurity density than that of substrate 1 is provided, the threshold level of the memory element becomes high and even if a voltage of approximate 5V is applied to gate layer 8, no channel is generated. Further, the avalanch breakdown voltage of the PN junction between regions 9 and 2a decreases and the write voltage also decreases.

Abstract: PURPOSE:To obtain a thermal head little affected by thermal stress and excellent in thermal responsiveness and printing performance by forming the heating body thin film divided into a plurality of dot areas on the end face of a base plate with a highly accurate shape characteristic and arranged structure. CONSTITUTION:After forming conductive copper patterns and thin copper films 20 and 30 for use on a common electrode on both the faces of an insulated base plate 10, a groove 12 is formed in the end face of the base plate, which is then divided into a plurality of dot areas 13. A heating body thin film 40 is deposited on the dot area 13 by sputtering.
