Title: Data erasion detecting device for volatile memory
Inventor: OTA HIROSHI
IPC: G06F12/16
Filed: 1989-06-09
Abstract: PURPOSE:To obtain a data erasion detecting device containing a simplified circuit constitution by comparing the index data set to a volatile memory with the index data obtained before the supply of power is cut and deciding that the data stored in the volatile memory is erased when no coincidence is obtained between both index data. CONSTITUTION:A state where the electric power is supplied to a power circuit 6 from an external power supply is restored from a state where the supply of electric power is cut to the circuit 6 from the external power supply. Thus a switch of a separation circuit 5 is closed and the supply of power is restarted from the circuit 6. At the same time, the index data Z set at addresses A - D is compared with the index data Z stored in a ROM. If no coincidence is obtained between both index data in terms of just a single one of addresses A - D, it is decided that the data stored in a volatile memory is erased. Then 1 is set to a voltage defective flag and a main process is carried out.

Title: Motor controlling system
Inventor: YAMAGISHI JIYUICHI
IPC: H02P29/00
Filed: 1981-09-17
Abstract: PURPOSE:To reduce the side of the entire motor controlling system and to enhance the efficiency of the system by varying a loop gain in response to a load and suitably selecting the set speed of a motor in response to the load. CONSTITUTION:A multiplier generator 10 receives a control signal from a load type detector 11 and generates a gain control signal of a variable gain amplifier 5 obtained by multiplying K times by the control signal. Accordingly, the gain G of the amplifier 5 is varied in response to the type of a type wheel. When the amplifier 5 is controlled so that the G is increased in case of a heavy load and is decreased in case of a light load, a speed control signal outputted from a comparator 13 becomes small in case of the heavy load, thereby decelerating the speed of a DC motor 2, while when the load is light, the speed is accelerated. Consequently, the gain can be varied in response to the type of the type wheel of the load, thereby accurately controlling the speed.

Title: Diaphragm type liquid feeding valve
Inventor: MIYAZAWA SHIYOUZOU
IPC: F16K47/02
Filed: 1983-08-10
Abstract: PURPOSE:To restrict a water hammering phenomenon by connecting a main valve main body whose backpressure chamber is formed by a diaphragm and an operation valve, which operates this diaphragm, by means of a backpressure pipe in order to separate the above two into two separated bodies. CONSTITUTION:When a operation valve is closed, water feeding pressure reaches a backpressure chamber 30 through a small hole 35, while a diaphragm 27 is brought in contact with an annular valve seat 32 by pressure owing to the force of a spring 31 so that a flow passage from a water feeding port 22 toward a water feeding hose 39 is shut. Since the discharging hole of the operation valve is larger in diameter than the small hole 32 of the diaphragm plate 28, when the operation valve is opened, water feeding pressure in the backpressure chamber 30 is gradually decreased in order to open the annular valve seat 32. By operating the diaphragm gradually like this, a water hammering phenomenon can be prevented.

Abstract: PURPOSE:To reduce the size of the hardware constitution of a control means by providing a 2nd tag means stored with 1st cache position information in the control means. CONSTITUTION:The 2nd tag means 108 stored in the 1st cache position information 112 indicating which processor 101 in the processor group of each control means 102 has each data in its 1st cache means 107 is provided in the control means 102 corresponding to the data 111 indicated by the 1st tag means 106 of an optional processor 101 in the processor group. Then each control means 102 updates corresponding 1st cache position information 112 on the 2nd tag means 108 as the contents of an optional 1st or 2nd cache means 107 or 109 are updated. Therefore, whatever way constitution the 2nd tag means 108 has, the data 111 on the 1st cache means 107 in this processor group can be grasped uniformly from the side of the control means 102. Consequently, the cache memory can be composed of a physically small number of memory chips and the hardware constitution of the control means is reducible in size.

The molten metal is retained in temp. in the solidified circular conical cylinder part so that the sticking of the molten metal to the bushing side is prevented. The flow of the molten metal in the grooves 19 in provided with the directivity by the solidification in the sprue part 20 and the molten metal is smoothly packed from the runners into the cavity. The decrease of the quantity of the heat of the molten metal and the decrease of the packing speed thereof are prevented and the packability is improved.

Title: Detecting method of flow quantity of molten slag
Inventor: NAKAHARA TAKAFUMI
IPC: C21B3/08
Filed: 1978-12-01
Abstract: PURPOSE: To detect the flow quantity of molten slag exactly by making the molten slag into fine particles by means of high speed air flow and by measuring thermal radiation from the fine particles of slag.  
     CONSTITUTION: Air is injected from the air feed nozzle 11 into the molten slag 10 to make it fine particles. Thermal radiation is measured by the radiometer 14 that is monitoring the slag particles. Temperature of the molten slag is on the order of 1400W1500°C, it is approximately constanr regardless of the flow quantity. Thus, it can be considered that radiation from one particle is approximately constant. However, radiation heat received by the radiometer is from the whole particles, the output of radiometer, which is proportional to the flow qunatity of slag, is shown since the quantity of particles is proportional to the flow qunatity of slag.
