Title: Picture storage device for special effect
Inventor: KASHIKI KAZUO
IPC: H04N5/907
Filed: 1984-01-31
Abstract: PURPOSE:To make the read speed of a picture elements string high within the permissible range of the access time of plural storage circuits and to read simultaneously plural storage circuits at a high speed by giving an input data and a write address in common to the plural storage circuits. CONSTITUTION:When the input picture elements string comes, it is written alternately in the storage circuits A, B at each input and when the write is finished, a write address is increased one by one. The even number order data is written in the storage circuit A and the odd number order data is written in the storage circuit B. In reading the data, when the picture element data corresponding to, e.g., 2.5, is desired, the data 2, 3 are read at the same time from each storage circuit and the data corresponding to the 2.5 is generated from the said data by interposition. Read addresses a, b fed to the storage circuits A, B are obtained by rounding simply off the LSB or rounding off it after 1 is added to the integral part of the read address.

Title: Surface-treated graphite and monolithic refractory containing the graphite
Inventor: TAKAGI MASATO
IPC: C04B35/66
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To improve the oxidation resistance of a graphite and obtain graphite- contg. monolithic refractories good in execution performance by depositing and fixing a boron compd. coated with an org. resin on the surface of graphite mother particles. SOLUTION: The surface of graphite particle as the source material is coated with a boron compd. such as boron oxide. This boron compd. is prepared by coating the surface with an org. resin such as a silicone resin. The obtd. graphite after the surface treatment is incorporated by bout 4 to 40wt.% as a skeleton component into the monolithic refractories. The particles of the source material graphite used are preferably to have about 1 to 50μm average particle size. As for the source material graphite, natural flake-type graphite, natural graphite soil or artificial graphite can be used. The packing bulk density of the surface- treated graphite is specified to >=0.8g/cc. As for the org. resin, a silicone resin or fluorocarbon resin for coating is used. By this method, the hardening at the execution time of the monolithic refractories can be prevented from delaying.

IPC: F04C29/02
Filed: 1984-01-31
Abstract: PURPOSE:To prevent the compression disorder phenomenon by cutting-off an oil feeding passage which communicates to the bottom part of a vane groove from an oil reservoir for a certain time after the stop of operation and increasing the sectional area of the flow passage for a certain time after start and allowing the vane to be pressed sufficiently even on start when the pressure difference of a compressor is small. CONSTITUTION:When a compressor stops operation, a plunger 23 is shifted by the pressure difference of the compressor and an oil feeding passage 16 is cut off, and at the same time, a valve piece 27 shifts to allow an auxiliary passage 29 to communicate to the oil feeding passage 16.

Title: Grinding using abrasive wheel consisting of superhard abrasive grain
Inventor: IMAI TOMOYASU
IPC: B24B49/18
Filed: 1986-01-29
Abstract: PURPOSE:To speedily reduce the grinding resistance immediately after trueing by carrying out the grinding work by reducing the peripheral speed of an abrasive wheel below the normal peripheral speed, immediately after the trueing of the abrasive wheel, and then carrying out the grinding work by restoring the normal peripheral speed of the abrasive wheel. CONSTITUTION:Because the cutting quality of an abrasive wheel 12 is bad and the grinding resistance is high, immediately after trueing, grinding work is carried out by reducing the peripheral speed of a grindstone according to the grinding resistance. The control of the peripheral speed of the grindstone is carried out through the inverter control corresponding to the grinding resistance detected by a grinding resistance detector 35. Since the load applied onto one piece of the superhard abrasive grain of the abrasive wheel 12 is increased by the reduction of the peripheral speed of the grindstone, the damage applied onto the abrasive wheel 12 is increased, and the superhard abrasive grains are actively broken, and the formation of acute cutting edge is accelerated. Therefore, the rate of reduction of the grinding resistance for the grinding quantity is increased, and the speedy restoration to the ordinary grinding resistance is permitted.

Title: Speed detector of wound-rotor type motor
Inventor: SHIMIZU TATSUO
IPC: H02P27/04
Filed: 1981-02-10
Abstract: PURPOSE:To eliminate the effect of the fluctuation of the primary winding power supply voltage and at the same time to obtain the voltage proportional to the speed, by applying the addition and subtraction to the voltage proportional to the secondary voltage of a motor and the voltage proportional to the primary winding power supply voltage. CONSTITUTION:The voltage proportional to the secondary voltage E2 of a wound-rotor type motor IM is detected by a transformer TR2 and then applied to an adder/subtractor circut AD after receiving the rectification through a rectifier D2. On the other hand, the voltage proportional to the primary winding power supply voltage Vs is detected by a transformer TR1 and rectified by a rectifier D1 to be supplied to the circuit AD as a bias via a variable resistor RB. The voltage E2 and the output voltage EDC of the rectifier D2 have the linear change to the change of the speed N but are not proportional to the speed. In this connection, the voltage EDC is converted to be proportional to the speed N. Accordingly the output voltage VD of the circuit AD becomes proportional to the speed N.
