Title: Water feeding valve
Inventor: SATOU TOMIYOSHI
IPC: F16K47/02
Filed: 1978-09-08
Abstract: PURPOSE: To prevent the swinging motion of the diaphragm valve body in operation, and to reduce the corrosion of the diaphragm valve body and the generation of noise by gradually throttling the flow of the fluid by the valve.  
     CONSTITUTION: When the valve is open, the valve rod 4a of the diaphragm valve body 2 contacts the rib 19 to actively guide the movment of the valve body 2. Therefore, the horizontal swinging motion of the valve body 2 can be controlled to the minimum. When the supply of electricity to the coil 8 is stopped, the working rod 11 is pushed down by the spring 12 to close the small port 4e. Then, the pressure in the pressure chamber 20 goes up again, and the valve body 2 gradually moves toward the valve seat 1d. In this case, as the tilting surface 4g at the top of the valve rod 4a first enters the valve seat 1d and then the small diameter part 4c enters, the flow of the fluid is gradually throttled from the high flow rate to the low flow rate, and the harmful hammering phenomenon can be reduced. Also, as the valve body 2 closes extremely slowly, noise caused by the high fluid pressure impact does not generate.

Abstract: PURPOSE:To detect abnormality with lamp alone and both of the lamp and a silicon control rectifier element by applying the outputs of the connection point of the lamp and the silicon control rectifier element to the input of a differential amplifier, and comparing and monitoring the same with the reference voltage. CONSTITUTION:If the output of an AC power source 5 and the output of the 1st DC power source 8 are applied to the circuit of a lamp 6 and a silicon control rectifier element 7, the voltage at the point A2 shifts by the 1 volt of the voltage E of the power surce 8. On the other hand, a differential amplifier 11 is applied with the divided voltage from a voltage dividing circuit 10 to its positive input (+) and the reference voltage from the power source 9 to its negative input (-), and compares both. Then, a decision circuit 18 is receiving a sampling signal C properly from a sampling generating circuit 17 and therefore the output of a terminal SV at the time when it is received is read and the presence or absence of any abnormality of the lamp and the element 7 is decided by the standard shown in the table.

Abstract: PROBLEM TO BE SOLVED: To improve the availability and transmission rate of a transmission channel. SOLUTION: A personal handy phone system(PHS) terminal PS sends a download request for desired data to be downloaded from a server 2. When a data amount to be sent is larger than a preset threshold value, the PHS terminal PS and the server 2 change the slot number ratio of transmission/ reception for incoming communication : outgoing communication from 1:1 to 1:7. Then the server 2 continuously sends divided data to the PHS terminal PS in the unit of 7 slots, and while confirming reception of one slot, the PHS terminal PS sends/receives all data. When the transmission/reception of all data are finished, the slot number ratio is restored to the conventional mode of the ratio 1:1.

Title: Data processing system
Inventor: SUZUKI KOJI
IPC: G06F3/06
Filed: 1985-05-24
Abstract: PURPOSE:To detect securely the temporary variation of a status signal outputted from a disk driver by generating an interruption signal to a CPU on the basis of the variation of the status signal to a latch means. CONSTITUTION:When the status signal READY from the disk driver is at a level L indicating a ready state, the output QFF of an FF1 is held at the level L. When the signal READY changes to a level H temporarily, a AND gate G1 generates an H-level output and the FF1 is inverted in synchronism with a clock E, so that the output QFF changes from L to H. Consequently, an inverter INV2 supplies an interruption request signal IRQ to a CPU, which holds a read signal at H so as to read the contents of the FF1. Consequently, a read out control signal CS' changes from H to L and a buffer BFF is opened to supply the output QFF of the FF1 to the CPU as a status signal RD indicating that the status signal READY enters a not ready state, so that the CPU detects that.
