Filed: 1979-12-28
Abstract: PURPOSE: To stop a torch invariably at an aimed stop position with accuracy even if a shaking speed is different, by using as a stop signal the output signal of a comparator that compares the signal of a function generator with that of a speed generator.  
     CONSTITUTION: At position 19 preceding stop position 18, side part 14 of projection part 13 of striker 12 coincides with detection part 16, which outputs a detection signal and at the position where the center of projection part 13 coincides with detection part 16, the movement stops. Namely, the position short of the stop position by a half width W of projection part 13 of the striker is detected as a stopping precedent position. A signal obtained by detecting the precedent position is sent to function generator 2, which starts function generation to supply its signal to comparator 4. Meanwhile, shaking-speed signal generator 3 is capable of generating a signal (voltage) proportional to a shaking speed and the signal is fed to comparator 4.

Title: Pressure regulator with gas cutoff mechanism
Inventor: SUGANOBU SATOSHI
IPC: F16K17/36
Filed: 1985-08-07
Abstract: PURPOSE:To improve safety, by regulating an inlet pressure so as to obtain a pressure range where a cutoff mechanism is surely actuated in an abnormal outflow condition of gas. CONSTITUTION:If a valve unit 40 is closed by the pressure of gas introduced from an inlet pipe 20, a pressure in a primary pressure reducing chamber A is decreased, as the result, a diaphragm 30, swelling to the bottom part side by the atmospheric pressure and the urging pressure of a spring 34 to lower an interlocking piece 44, opens the valve unit 40 through a valve rod 42. In this way, the pressure in the primary pressure reducing chamber A comes to continually hold a fixed value within a fixed pressure fluctuating range. Even when the original pressure in a gas supply side is in a high level, a regulator, setting the pressure of gas supplied from inside the primary pressure reducing chamber A to a pressure range performing the cutoff action by an actuator rod 48, enables the action to be surely performed.

Abstract: PURPOSE:To measure the thickness of even a thick film by calculating the capacitor capacity of a space charge layer from waveforms of a light voltage and a photocurrent generated by optical excitation, and calculating the film thickness. CONSTITUTION:A voltage is impressed to a reference electrode 5 for pure iron 4 by a potentiostat 6 to flow a current between the pure iron 3 and platinum 4, and a passive film is formed on the surface of the pure iron 3 simultaneously. A xenon lamp 11 is turned on after the current becomes almost stable at a constant value, and its light is intermitted by a lamp chopper 9 and converted on the passive film of the pure iron 3 through a transmission window 8. At this time, the current is affected by the light to cause variation based upon the migration of an electron-hole couple due to optical excitation. Then, circuit switches 16 and 17 are switched to a galvanostat circuit to flow a current between the pure iron 3 and platinum 4 so that the potential of metal 3 is equal to that at the time of the potentiostat circuit, thereby calculating the voltage variation due to the optical excitation of the metal 3. Then, the thickness of the film is calculated from said light voltage and photocurrent.

Title: Fluid torque amplifier
Inventor: NAKAJIMA KENJI
IPC: F04B23/04
Filed: 1995-06-05
Abstract: PURPOSE: To amplify torque without reducing rotating speed in manual operation or a motor by a combination of plural pumps different in a diameter and a pressure adjusting tank. CONSTITUTION: When cylinder capacities of a large pump A and a small pump B are set in the same with each other, rotating speeds of the large pump A and the small pump B becomes the same with each other. An inside diameter of a cylinder of the large pump A and an inside diameter of a pipe C and a pipe E are set in the same with each other. Since a pressure adjusting tank C is larger in an inside diameter than a pipe D, fluid housed in the pressure adjusting tank C reduces in pressure, and when the fluid enters the large pump A from the pipe E, resistance is reduced. When cylinder capacity of the small pump B is smaller than cylinder capacity of the large pump A, rotation of the small pump B becomes faster than the large pump A, and when the cylinder capacity is larger, rotation becomes slow.

Abstract: PURPOSE:To provide a card with a card identification code which can be easily identified on the surface and which is protected against forgery by constituting a heat-absorbing stripe on the surface of the card using a heat-absorbing agent and detecting a temperature difference on the heat-absorbing strip after heating as the card identification code. CONSTITUTION:A thick part of a large thermal capacity and a thin part of a small thermal capacity are alternately arranged in an oversheet 4 on the surface of a card or in a center core material 1 of a heat-absorbing material 2. A card type identification code can be composed by selecting the interval between the arrangements of heat-absorbing material 2 properly. Then the card is transported by a transport roller for heating 6 with the concurrent heating of the card. Consequently, the temperature difference generates between the part of a large thermal capacity and the part of a small capacity of the heat-absorbing material 2. This temperature difference on the surface of the heat-absorbing stripe is detected as a differential output equal to a difference in radiative infrared ray power using an infrared ray detection element 3. Next the temperature difference is amplified by a signal detection circuit 8 into a converted voltage pulse and this pulse is output as a card identification code.
