Title: Computer checking method
Inventor: TOMOSAWA KIKUO
IPC: G06F11/22
Filed: 1985-03-27
Abstract: PURPOSE:To check a computer regardless of various conditions during the check including the temperature, humidity, etc. by transferring a check program to a read-write enable memory and jumping the operation to the transferred check program for execution of said program. CONSTITUTION:When a switching circuit is started by a control circuit 12, the instruction sent from an address 'O' is replaced temporarily with a jump instruction to have a jump to the head address of a transfer program stored in a transfer ROM 7 by jump instruction generating circuits 9a-9c. When the jump instruction is executed, the processing proceeds to the head of the transfer program. This program contains a program to transfer the whole or a part of a check program stored in a ROM 8 to be transferred to a RAM 4 in a computer 1. Then the procedure is jumped to the head address of the RAM 4 after said transfer of the check program. thus the computer 1 executes the check according to the transferred check program.

Title: Positioner
Inventor: FUKUDA MINORU
IPC: F15B9/07
Filed: 1993-02-26
Abstract: PURPOSE:To eliminate generation of any drift in a valve opening near the valve opening target value. CONSTITUTION:In a control unit 20, a valve opening setting signal is received from an outer controller, and an electropneumatic conversion unit is controlled by feed back of an opening position signal from a position sensor 25. After the deviation between the set opening and a valve real opening comes in a prescribed range, feed back control is carried out by an air pressure signal from a pressure sensor 27 for detecting an output pressure to the driving unit 24 of a pilot valve 23. Since there is no influence of frictional resistance of a valve seal packing, any drift in a valve opening is eliminated when the valve opening comes near the set opening, and also responsiveness can be improved.

Title: Semiconductor device
Inventor: HAIJIMA MIKIO
IPC: H01L21/8226
Filed: 1979-05-25
Abstract: PURPOSE:To equalize the injection current for improving the working margin by changing the contact form of I<2>L unit injector electrode or the breadth of base of a horizontal-type transistor. CONSTITUTION:In a p-type layer 3 of I<2>L unit horizontal-type pnp transistor injector, a contact part 7 with an electrode is made into a long the slender triangle, the breadth d1,d2 is made gradually larger from the initial end to the final end of the flowing-in injection current. As the breadth of the p-type layer 3 is uniform, at the initial part with the small breadth d1 the resistance from the contact part to the pn-junction is large, while at the final end with the large breadth d2 the resistance reduces in the same way when the ballast resistance is set to. Consequently the portion of fall of potential from the initial end to the final end of the wiring resistance is compensated, the injection current to each collector (reverse npn transistor base) is equalized to improve the working margin. Also the change of the breadth of n-type base 2 produces the same effect.
