Patent JP-S62163919-A (JP)
Title: Rotary encoder
Inventor: ISHIZUKA AKIRA
IPC: G01D5/38
Filed: 1986-01-14
Abstract: PURPOSE:To measure the rotating state of a rotating object to be inspected with a high accuracy while miniaturizing the equipment as a whole, by making reciprocating optical paths the same for specified order of diffraction lights from a polarized beam splitter to a reflection means. CONSTITUTION:A luminous flux radiated from a laser 1 is projected parallelly into a polarized beam splitter 3 so that it is divided into two linearly polarized lights - reflected light flux and transmission light flux of roughly equal quantity of light. The reflected luminous flux is projected as circularly polarized light into a position M1 of a radiation grating 7 provided with a radial diffraction grating on a disc 6 linked to a rotating object to be measured via 1/4 wavelength plate 4. Among transmission diffraction lights incident into the radiation grating 7 and diffracted, those of a specified order are reflected by a reflection means 8 and reversed in the same optical path to be made incident into the almost the same position M1 on the radiation grating 7 again. Then, the diffracted light of a specified order diffracted again with the radiation grating 7 is turned to a linearly polarized light differing by 90 deg. in polarization bearing from that when projected through the 1/4 wavelength plate 4 to be entered into a polarization beam splitter 3.

Abstract: PURPOSE:To effectively use a CPU and resources such as memories by preventing an unrequired process from being present on a main storage. CONSTITUTION:An unrequired process detecting part 14 detects a process which satisfies a prescribed condition in the processes set in idling states, or the process with an execution file name decided in advance as the unrequired process based on information in a process table 13, and the complusory completion of the unrequired process is performed by a process managing part 11. In such a case, a compulsorily completed process is automatically deleted from the memory 21 and the process table 13. Thereby, a state where only required processes are stored in the memory 21, and no unrequited process is present on the memory can be set. Therefore, it is possible to reduce the unrequired completion operation of the process by a user and the wasteful usage of the resources by the unrequired process.

Filed: 1995-01-19
Abstract: PURPOSE: To make thin a cartridge and the entire recorder by employing a metal plate at least on one side of the cartridge and disposing a field generating means on the inside of the metal plate. CONSTITUTION: A cartridge 2 (2a and 2b) loaded on a magnetooptic recording medium 1 is formed of a soft magnetic metal plate 2a at least on one side thereof.

Title: Remanent magnetism removing device for smacc electromagnet
Inventor: NIWA HIDEO
IPC: H01F7/18
Filed: 1995-01-19
Abstract: PURPOSE: To remove remanent magnetism sufficiently in a simple circuit constitution. CONSTITUTION: To an exciting coil 3 of a compact electromagnet, a capacitor 6 is connected in parallel, and the series circuit of a reactor 7 and a first reverse current blocking diode 8a is connected to the capacitor 6 in parallel. To the exciting coil 3, the parallel circuit of a second reverse current blocking diode 9 and a constant-current diode 10 is connected in series. When a power supply is cut off, the exciting coil 3 discharges the magnetic energy to the capacitor 6 through the second reverse current blocking diode 9, and the reactor 7 discharges the magnetic energy to the capacitor 6 through the first diode 8a. Thus, the capacitor 6 is charged in reverse polarity. The charged electric charge of the capacitor 6, which is charged in the reverse polarity, is transformed into the constant current through the constant current diode 10.  The constant current reversely excites the exciting coil 3. The constant current value is set at the specified value, where the remanent magnetism can be made to be approximately zero.

Filed: 1989-01-13
Abstract: PURPOSE:To perform a fast processing by constituting a system so that a register window used by a procedure called in the past can be saved to the stack of a memory in advance. CONSTITUTION:An instruction is latched at a register 1, and is decoded by a decoder 2, then, a control signal is generated. The control signal is supplied to a control logic circuit 3, and the control signal for storing the register window is generated. Those control signals are latched at a register 4. Also, most the control signals are inputted to a counter 5, and a count value is inputted from a comparator 6 to the circuit 3 via a register 11. The circuit 3 saves the register window set at a register file to the stack in sequence of setting the register window based on the storing state of a state register 7 and the compared results of the count values by the comparator 6 while no instruction to perform a procedure call, etc., is issued from the decoder 2. Therefore, no saving processing is performed even when the overflow occurs in the register file.

Title: Differential amplifier circuit
Inventor: NANBA KIYOSHI
IPC: H03F3/45
Filed: 1988-01-18
Abstract: PURPOSE:To reduce a offset voltage by connecting the base of a fourth transistor having reverse polarity a third transistor with the collector of a first transistor and connecting a constant current source with the emitter of the fourth transistor. CONSTITUTION:The base of the fourth PNP transistor Q6 having the reverse porality is connected with the base of the third NPN transistor Q5, and the constant current source I3 is connected with the emitter, whereby the base is connected with the collector of the first transistor Q2. Since the base current of the transistor Q6 is decided by the current of the constant current source 13 and the current amplification factor of the transistor Q6, the current supplied to the transistor Q5 is compensated by the transistor Q6 when the base current is set to the same value as the base current of the transistor Q5. Thus, the collector current of the transistor Q2 is compensated and a difference between the operation currents of the transistors Q1 and Q2 consisting a differential circuit can be reduced, whereby the offset voltage can be reduced.

Filed: 1978-01-24
Abstract: PURPOSE: To realize the pretreatment to remove completely the contaminative materials on the surface of the diffusion process tube through washing via the hydrofluoric acid and aqua regia.  
     CONSTITUTION: The rare hydrofluoric acid is filled inside tube 1 to fuse the silicon oxide on the inner surface of tube 1. Thus the contaminative materials are removed from the tube surface, and then the inside of the tube is washed with the demineralized water. Then the aqua regia is filled inside the tube about one hour to delete away the heavy metals (contaminative materials) which were not removed through the pretreatment. After this, the inside of the tube is washed completley with the demineralized water, and the tube undergoes the diffusion process of the semiconductor wafer. In case tube 1 is made of Si, quartz cap 3 is connected and the oxygen gas is introduced into tube 1 from the side of the arrow mark and then heated up by heating coil 4 wound outside the tube. Thus, an oxide film is formed on the tube surface. As a result, the intrusion of the diffusion dopant into tube 1 can suppressed in the diffusion process.
