Patent JP-S5443393-A (JP)
Title: Electric discharge machine
Inventor: GAMOU GOUTAROU
IPC: B23H1/02
Filed: 1977-09-12
Abstract: PURPOSE:To remarkably improve the reliability of the shortcircuit detection. CONSTITUTION:An average working voltage is monitored as a terminal voltage of a capasitor C2. When this voltage is below the first reference voltage (set with a resistance VR2), it is determined that a short circuit takes place between electrodes and thus, the output of a comparator Q2 becomes zero. As a result, the output of a gate N1 turns to 1 and a mid-working signal shows O. Then, a pulse oscillator OS is stopped, suspending the on/off action of the transistor, eventually making it open. Due to this, a high voltage source Vs is separatdd away between the electrodes and hence, with a low voltage source VL, a current flows in the route of the ground, work, an electrode phi, a diode D1, and the power source VL, so that the voltage at a point A exceeds the second reference voltage causing the comparator Q1 to turn to O. When the short circuit between P and W is got rid of, the cmparator Q1 turns to 1, and the signal CC turns to 1 to resume working.

Abstract: PURPOSE:To join firmly both a core material and a roll outer layer sleeve, and to prevent crack damage from occurring in the course of use by making the thermal expansion quantity of the core material larger than the thermal expansion quantity of the sleeve, when inserting and fitting the roll outer layer sleeve into the core material, and heating and joining them. CONSTITUTION:A roll outer layer sleeve is fitted into a core material or an inside inserting material such as an inner sleeve, heated and made raised in temperature in a nonoxidative atmosphere, joint surfaces of both of them are diffused and joined, and a rolling roll is manufactured. In this case, the thermal expansion quantity of the core material is made larger than the thermal expansion quantity of the outer layer sleeve, and they are combined so that the joint surfaces are adhered tightly by a difference between the thermal expansion quantities. Especially, as for the core material, the thermal expansion quantity after an Ac1 transformation is made larger than the thermal expansion quantity of the outer layer sleeve so as to be joined at a temperature of an austenite area, and in case a usual roll material of a cast iron or cast steel compound is used for the outer layer sleeve material, as for the core material, it is desirable to use a ductile cast iron material.

Title: Electronic apparatus incorporating back-up function of memory
Inventor: KATSURA HIROO
IPC: G06F1/00
Filed: 1979-08-29
Abstract: PURPOSE: To ensure an visual recognition for the back-up breakage of the memory and thus avoid the mixture with other display or print or prevent the misrecognition, by giving the print or display for the message warning the breakage of the memory information.  
     CONSTITUTION: When the service interruption or power supply off deciding part BJ decides the off of power supply, the transfer control part SC transfers the contents of the ROM register X to the memory M in the RAM via the gate G. At the same time, the recovery of the voltage after the on of the power supply or the service interruption is decided by the deciding part AJ, and thus the coincidence deciding part J gives a decision by the control part RC between the contents of the register X and that of the memory M. And in case no coincidence is obtained, the character code generating part CRG sends the character code "LOW BATTERY" indicating the "breakage of back-up of RAM" to the print/display control part. Thus the back-up breakage of the memory can be recognized visually to avoid the mixture with other display or print or prevent the misrecognition.
