Filed: 1980-05-24
Abstract: PURPOSE:To improve the reliability of a device, by providing an interface(IF) which transfers a microprogram(muPG) and data between respective loader microprogram controllers(MPU) of plural independent controllers. CONSTITUTION:Controllers A and B which are incorporated into the same housing and are independent of each other are composed of main MPUs 1 and 5, loaders MPU 2 and 6, loaders 3 and 7, and IFs 4 and 8 respectively, and each main MPU loads a muPG from a loader through the loader MPU and operates. Assuming that a fault occurs in the loader 3, MPU2 recognizes the fault of the loader 3 after several retries and interrupts the IF8 through the IF4.

Abstract: PURPOSE:To prevent the output of overvoltage even if manual gain control is switched to automatic gain control by adding a DC voltage from the outside to a detected value outputted from an amplifier and comparing the added value with the reference voltage of a comparator at the control of the amplifier under manual gain control. CONSTITUTION:When switching circuits SW2, SW3 are connected to a manual gain control (MGC) circuit, a voltage from a terminal 2 is applied to an amplifier AMP-1 through a variable resistor RV1, a signal from a terminal IN is amplified at a certain gain, a part of the output is applied to a detector DET through a hybrid circuit HYB and a capacitor C1 is charged by the voltage detected by the DET. A DC voltage from a terminal 1 is also charged to the capacitor C1, the charged voltage is compared with the reference voltage of the comparator COM and the difference voltage is amplified by an AMP-2 to obtain the voltage minimizing the gain of the AMP-1. When the switches SW2, SW3 are turned to an automatic gain control (AGC) circuit under said condition, the AMP-1 increases gain gradually from the minimum gain up to a prescribed output level, so that overvoltage is outputted.

IPC: H02K5/00
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a shield tube that has improved shielding property against noise at low costs and an improved machining property. SOLUTION: A shield tube 2 is formed cylindrically along the outer shape of a motor 25, using a material less expensive than the permaloy that is a type of iron-nickel magnetic alloy generally used, which is free-machining steel (SUM) made by adding sulfur to a carbon steel to improve machinability. The SUM has a drastically higher permeability among steel materials being used generally according to an experimental result. By surrounding the periphery of the motor 25 with a material of high permeability, a magnetic flux as noise which is generated by the rotation of the motor 25 flows to the material of high permeability and is less frequently diffused toward the outside. With such a magnetic shield, the shielding effect against noise can be fully utilized.

Title: Bit string comparing system
Inventor: TORII SATOSHI
IPC: G06F7/02
Filed: 1988-03-24
Abstract: PURPOSE:To prevent a bit string having meanings different for a bit from being seen as a binary number by executing a comparison for the bit and permitting a comparison result that a largeness relation is undefined. CONSTITUTION:When '1010' and '0010' are given as a first binary digit string 31 and a second binary digit string 32, respectively, a mask computing element 21 compares values stored in registers 11 and 12 for mutually corresponding bits, and executes an operation to output '0' when the bit in the register 11 is '1' and to output the corresponding bit in the register 12 as it is when the bit in the register 11 is '0'. On the other hand, a mask computing element 22 compares the stored values for mutually corresponding bits, and executes the operation to output '1' when the bit in the register 11 is '0' and to output the corresponding bit in the register as it is when the bit is '1'. Further, a comparator 23 makes the output of the mask computing element 21 into an input, outputs '1' when every bit is '0', and outputs '0' otherwise. Thus, the comparison of arbitrary binary digit strings can be easily executed.
