Abstract: PURPOSE: To provide a simple, inexpensive and precise driving device for rotating the spindle of an electrical discharge machine. CONSTITUTION: This driving device for the spindle of an electric discharge machine comprises an electric motor adapted to be operated to rotate in two opposite directions and a reduction gear box assembly operatively coupled to the electric motor. The gear assembly is provided with a pinion 41 and two gear wheels 33, 35 rotatable with reference to each other. Both the gear wheels 33, 35 engage with the pinion 41. One of the gear wheels 33, 35 is under the influence of a torsional biasing force. The first gear wheel 33 is fixedly connected to the spindle of the electric discharge machine in the torsional direction, while the second gear wheel 35 is rotatable with respect to the spindle. Such a driving device operates with low expenditure without backlash in both directions of rotation whereby an eventually occurring wear is automatically compensated.

IPC: G01R31/36
Filed: 1981-12-28
Abstract: A process and apparatus for determining the state of discharge of an electric battery by measuring the voltage drop associated with changes in its internal resistance. According to the process, the battery is periodically connected to a reference load for a brief interval during which the voltage at the terminals of the load is measured. The measured analog voltage is converted to a digital signal which is compared to a number of pre-programmed digital levels to determine the state of change of the battery. The apparatus comprises a commutation component controlled by a logic signal, a reference load, a sampler-and-hold circuit, an analog-to-digital converter and a comparator which can be programmed at n levels. The apparatus compares digital signals corresponding to the voltage at the terminals of the reference load with the n programmed levels of the decoder and a signal is generated indicating the level of the electric battery with respect to the levels programmed into the comparator.

Abstract: PROBLEM TO BE SOLVED: To improve the operability of a mobile telephone set by depressing a specific key to set an automatic answering telephone mode, hooking off to output a reply message and recording the message from a caller, in the case that an incoming call arrives while the automatic answering telephone mode is not set. SOLUTION: A mode changeover key 21 provided at a key entry section 2 enters an instruction to allow a control section 3 to set the operation mode to be a normal mode or an automatic answering telephone mode. When the mode changeover key 21 is depressed in the normal mode, the normal mode of the control section 3 is switched into the automatic answering telephone mode, and when the mode changeover key 21 is depressed in the automatic answering telephone mode, the automatic answering telephone mode of the control section 3 is switched into the normal mode. Thus, even when the automatic answering telephone mode is not set in the standby a state and a phone call is received during a conference, the mode is switched to the automatic answering telephone mode in one operation.

Abstract: PURPOSE:To prevent a lack of torque even if a pressure setting screw is tightened, by fixing a magnetic member to be attracted to means which controls the elastic force of the pressure setting spring and arranging a magnetic member which attracts the magnetic member to be attracted when the control means is tightened. CONSTITUTION:A desired set pressure is inputted through a controller 32. A fluid pressure in the secondary side is measured by a pressure sensor 40, and the deviation between the fluid pressure in the secondary side and a set pressure target value is detected by a comparison adjuster 31 and is compared with a prescribed deviation reference value; and if the deviation detection value is larger than the deviation reference value, the operation signal of an actuator is sent to a driver so that the deviation detection value is about zero. In this case, a magnetic member 42 to be attracted is fixed to the means which controls the elastic force of a pressure set spring 16, and the attraction of the magnetic member is increased to absorb the generated force of the pressure set spring according as the means which controls the elastic force of the pressure set spring is tightened. Thus, the generated force of the pressure set spring is absorbed to prevent a lack of torque for the actuator.
