Filed: 1983-11-02
Abstract: PURPOSE:To prevent an erroneous operation such as a stepout by arbitrarily altering the oscillating frequency of an oscillator, thereby freely varying the speed of a step motor which is operated by a closed loop. CONSTITUTION:A reference clock A generated from a frequency variable oscillator 5 is applied to one input of phase discriminating means 4, and a speed signal B representing the speed of a rotor from an encoder 2 is applied to the other input, thereby comparing the phases of the both signals by the means 4.

Title: Positioning controller for moving body
Inventor: MURAO HIROSHI
IPC: H01L21/67
Filed: 1986-09-01
Abstract: PURPOSE:To prevent an overshooting by setting a position deviation integral value in proportion to a position deviation at the time of starting a control as a negative initial value. CONSTITUTION:The positioning control device of a moving body such as an XY stage is composed of a position detecting part 11, a position deviation present speed arithmetic part 12, a CPU 13 and a moving body driving part 14. For the CPU 13, the position deviation and present speed of the moving body are inputted from the above-mentioned arithmetic part 12, each arithmetic operation in a proportion action system, an integral action system and a differential action system is executed and respective outputs are obtained. Thus, the position deviation integral value is obtained from a position deviation, the value in proportion to the position deviation at the time of starting the position control is set as the initial value of the position deviation integral value, and therefore, the integral value is canceled with the initial value. As a result, the overshooting at the target position of the moving body does not occur and a positioning setting time can be shortened.

Abstract: PURPOSE:To individually indicate the actuation of protective devices for a compressor without specially providing indicating lamps by using light-emitting diodes for the input-output indication part of a sequence controller for controlling the operation as lamps showing the condition of the operation and malfunctions. CONSTITUTION:When a thermostatic switch 19, an overcurrent relay 20, and a high- pressure switch 21, which all are protective devices for a first compressor, are not in action, a current passes through each of auxiliary relays 32-34 and all of contacts on the output side of a sequencer 30 close circuits so that an operation signal from the sequencer 30 causes an electromagnetic contactor 11 for a first compressor to be turned on, thus starting the compressor 6 operating. When the operation signal is outputted by the sequencer 30, a light-emitting diode designated by No.431 at the output indication part on the output side of the sequencer 30 is lighted to indicate the operation. As regards indications of abnormality relating to the compressor, when, for example, the high-pressure switch 21 is activated, the contacts open to shut off the current to an auxiliary relay 34; b contacts X4 connected to the input side of the sequencer 30 then close and a light-emitting diode designated by No.504 at the input indication part is lighted.
