Title: Position detector for driving cylinder
Inventor: KATO SHINJI
IPC: F15B15/28
Filed: 1989-06-14
Abstract: PURPOSE:To obtain a sufficient position resolution and to reduce the cost of materials by coating the surface of the shaft of a driving cylinder with a magnet film having a high coercive force, and magnetizing this film at a prescribed pitch in the axial direction of the shaft. CONSTITUTION:A magnetic sensor 7 consists of an MR (magnetic resistance) element and is attached to the end face of a driving cylinder 5 and faces a shaft 6 with a prescribed space between them. The magnet film and a protective film are successively constituted on the surface of the shaft base material of this shaft 6, and the magnet film is magnetized at a prescribed pitch in the axial direction of the shaft 6. When the cylinder 5 is driven to move the shaft 6, an output voltage is obtained from the sensor 7 because the magnetic flux generated around the magnet film in accordance with the magnetization pitch traverses the sensor 7. Consequently, peak points and zero-crossing points of the output voltage of the sensor 7 are counted to detect the extent of movement from a reference position.

Title: Track releasing device in caterpillar
Inventor: YOSHIDA KUNIHIKO
IPC: B62D55/32
Filed: 1981-09-25
Abstract: PURPOSE:To prevent accidents such as coming-off of a track and the like from occurring by a structure wherein a booster is interposed in the titled device, which adjusts the tension of a track, in order to increase the force to push an idler during the backward movement of a bulldozer. CONSTITUTION:A booster 30 is interposed in the pushing device to push an idler 4 of a bulldozer 1. In the structure as mentioned above, when the bulldozer 1 moves backward, high hydraulic pressure in a piping 35a is led into a large cylindrical chamber 33 of the booster 30 in order to push a piston 31 leftward. Consequently, grease in a small cylindrical chamber 32 of the booster 30 is supplied through a conduit 23 to a chamber 12a of a cylinder 12, resulting in pushing a spring retainer 13 rightward in order to compress a spring 14. Accordingly, a large pushing force is applied through a piston 11 and a rod 8 to the idler 4 in order to increase the tension of the track 6 so as to eliminate the slacking of the track.

Title: Air purifier
Inventor: MIURA TAKASHI
IPC: B01D46/42
Filed: 1988-06-17
Abstract: PURPOSE:To detect time for replacing dust collection parts by detecting the change in resistance value of a self-heating-type thermistor provided downstream a dust collection part as the change in voltage to find the change in flow speed of air. CONSTITUTION:A self-heating-type thermistor 11 and a thermistor for temperature compensation 12 are provided on the downstream side of a dust collection part 1. The resistance value of the self-heating-type thermistor 11 changes when it is cooled by air flow, whereby the change of flow speed of air can be found out from the change in voltage. The voltage change from initial voltage is measured and when the voltage has reached a set voltage, a light emission diode 15 is turned on so as to indicate the time for replacing dust collection part 1 or backwashing. Consequently, by detecting the flow speed of air on the downstream side of the dust collection part, clogging on the dust collection part 1 can be detected, resulting in a dust collector having an excellent maintainability.

Title: Rankine generator
Inventor: ISHII MASAHARU
IPC: F01K25/00
Filed: 1982-09-01
Abstract: PURPOSE:To prevent runaway of both an expansion machine and a synchronous generator and perform stable operation regardless of fluctuation in a heat source and load by detecting the pressure of an inlet side and an outlet side of the expansion machine and controlling an excitation electric current of the synchronous generator according to the signal of detection. CONSTITUTION:The working fluid, first receives heat from an outside high heat source through a steam generator 2, then it is expanded in an expansion machine 1 to discharge energy, next it is condensed in a condenser 3 and further liquefied, subsequently it is pressurized by means of a pump 5 and flows into the steam generator 2 again, while energy generated in the expansion machine 1 is converted into electric energy by means of a synchronous generator 6. At this time, each pressure at the inlet and outlet sides of the expansion machine 1 is detected by means of a pressure detector 8, and the signal of this detection is sent out to an excitation electric current regulator 9 along with signals of detection from a rotational speed detector 7. Further, through controlling excitation electric current sent out from the excitation electric current regulator 9 to the synchronous generator 6, rotational speed of the expansion machine 1 and the synchronous generator 6 are maintained constant, thus the expected purpose is attained.

Title: Manufacture of semiconductor element
Inventor: YAMADA SHINICHI
IPC: H01L29/74
Filed: 1995-06-19
Abstract: PURPOSE: To obtain a highly reliable semiconductor element which can prevent the occurrence of leak currents by providing a life time control means to a part on the inside of the bevel sections of a wafer. CONSTITUTION: The periphery of a semiconductor wafer and the part of the surface of a P-type emitter layer 1 of the wafer extended inward from parts to be beveled 6 are covered with a mask 7 and a vapor-deposited gold layer 8 is formed by vapor-depositing gold on the non-masked part of the surface of the layer 1 and diffused. Namely, when the diffusing source is formed by vapor deposition, the inside of the bevels 6 is covered with the mask 7. When this method is used, the breakdown strength of a semiconductor element can be improved without making an N-type base layer 2 thicker, changing the concentration, nor changing the gold diffusing condition nor proton irradiating condition.  The reason why the breakdown strength can be improved is that no depletion layer does expand to the part of the terminal section of the element which is not punched through, because life time control only of the inside of the bevels 6 is conducted.

Filed: 1977-12-15
Abstract: PURPOSE:To cause the equivalent effect of erasing an information unit from the buffer memory by the renewal of the address tag provided in the information unit, thereby performing high-speed erasure of the portion of discrepancy between the contents of the main memory unit and the buffer memory. CONSTITUTION:When write information to buffer memory 8 is ''1'' and the information unit name, address tag and block address agree among themselves together with the each field of the address for which access is requested, and when the write information is ''0'' and the information unit name and block address agree with each other, access is made to the corresponding buffer memory block.

In this way, erasure of only the portion concerning the occurrence of discrepancy between the contents of main memory unit 9 and buffer memory 8 can be performed at high speed.

Abstract: PURPOSE:To automatically control operation time of discharge electrodes by setting required time for spark erosion and operation time for discharge electrode driving motor to each respective motor timer. CONSTITUTION:With delayed operation time set to a motor timer 17 in advance, the contact point 26-26 becomes connected after a designated time and current is supplied to the coil 31-31 of an auxiliary relay 18 disconnecting contact  points 27-27 and 28-28.

The delayed operation time setting mechanism of the motor timer 15 or 17 returnes to its original setting condition when current in the coil 29-29 or 32-32 is lost. Thus, automatic control of operation time of discharge electrodes is accomplished.
