Title: Controller of dc motor
Inventor: MUNEYUKI MITSUO
IPC: H02P7/06
Filed: 1985-08-20
Abstract: PURPOSE:To obtain a controller of a small-sized inexpensive DC motor by composing a field-weakening branching circuit only with a rectification improving reactor having large resistance value. CONSTITUTION:A pulsating current branching resistor 3 and a field-weakening branching circuit 4A are connected in parallel with a DC motor field 2. The circuit 4A has only a rectification improving reactor 6A having large resistance value. Thus, since the reactor itself for forming a field-weakening branch also operates as a field-weakening resistor, the number of parts can be reduced, and the controller can be reduced in size and cost.

Title: Telephone exchange system
Inventor: TAJIMA HIROTSUGU
IPC: H04Q3/58
Filed: 1990-07-09
Abstract: PURPOSE:To flexibly set a line wire specifying number, and to prevent an erroneous line wire holding or connection by converting the arbitrary line wire specifying number inputted from a telephone set by a user, into the correct line wire number by a converting pattern memory. CONSTITUTION:When the arbitrary line wire specifying number is inputted from an extension telephone set 1, the dial signal is received by a dial signal receiver 3, and transmitted to a central provessing unit 4. The central processing unit 4 searches a converting pattern storing memory 5 each time receiving the dial signal, and searches the line wire number corresponding to the inputted line wire specifying number (received dial signal). Then, the central processing unit 4 decides which line among contained lines 7 is performed access to, and connects the extension 1 through an exchange switch 6 with the line wire. In this way, the central processing unit 4 flexibly sets the line wire specifying number inputted from the extension 1 to be converted into the number which is convenient for the user, after referring to the converting pattern storing memory 5. Thus, the erroneous specification of the line wire can be prevented.

Abstract: PURPOSE:To improve the write characteristic by successively switching a memory array to the next memory array by a control circuit at the time of arrival at a maximum frequency in rewrite or approximation to a write limit of write level monitor and continuing the nonvolatile memory operation. CONSTITUTION:Monitor elements 31 to 34 having the same structure as memory arrays 11 to 14 are used, and a store control circuit 21 is so set that the array 11 and the element 31 are operated at the time of power-on. When a store signal STO is inputted, a store pulse is generated, and the rewrite operation in only the array 11 is performed through a memory array switching circuit 26. Though the same store pulse is supplied to the element 31,  1' and '0' are alternately given as the data signal for rewrite by a '1'/'0' generating circuit 23. The write level of the element 31 is checked by a write level detecting circuit 25 at each time, and the write is performed up to the write limit. When the limit value is detected by the circuit 25, the circuit 21 is operated to quickly switch them to the array 12 and the element 32. Thus, the rewrite characteristic is improved.

Title: Mask sheet for sputtering
Inventor: MIYAMA MASAHIKO
IPC: C23C14/04
Filed: 1986-08-01
Abstract: PURPOSE:To prevent the warping of a mask sheet used to form thin SiC films and to shorten the time required to form the films by tapering the holes in the mask sheet so that they are extended toward an SiC flying direction. CONSTITUTION:When SiC is deposited on an insulating substrate by sputtering through a metallic or ceramic sheet 1 having holes 2 as a mask sheet, the holes 2 in the sheet 1 are tapered 3 so that they are extended toward an SiC flying direction. Since the mask sheet 1 for sputtering hardly casts a shadow on the substrate by the tapering even in case where the thickness of the sheet 1 is so increased as to make warp during sputtering negligible, the sputtering time required to obtain SiC films of a prescribed thickness is not prolonged. Accordingly, SiC films of the prescribed thickness are formed on the insulating substrate in a short time with little warp.
