Patent JP-H11138370-A (JP)
Title: Work piece working method
Inventor: MIHASHI HIROSHI
IPC: B23K26/38
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To perform efficient working with a burr eliminated by conducting rough cutting work through laser beam machining on a work piece composed of magnesium or its alloy, and then finishing with a grinding device or a cutting device. SOLUTION: When a work piece W composed of magnesium or its alloy is subjected to cutting work, at first, rough cutting work by laser beam machining on a laser cutting line, slight dross adheres to a cut surface. Consequently, a proper cut surface can not be obtained by only the rough cutting work, then, finishing is to be made on a machining line through a grinding device or a cutting device. Resultantly, a burr can be eliminated from the cut surface, thereby efficiently obtaining a proper cut surface.

Title: Frequency variable oscillation circuit
Inventor: TAKIGIRI KAZUYA
IPC: H03B5/12
Filed: 1987-12-01
Abstract: PURPOSE:To prevent abnormal operation such as the unstarting of oscillation or abnormal oscillation at the rise time of a power source by providing a switch circuit cutting the variable power source when the output of a voltage detection circuit which detects the level of supply voltage is below a prescribed value. CONSTITUTION:The voltage detection circuit detects the level of the supply voltage VCC and the switch circuits Q17 and Q18 cut the variable power source when the output of the voltage detection circuit is below the prescribed value. Therefore, the variable power source is cut until the supply voltage VCC reaches the prescribed value and a variable reactance circuit is not operated. Due to that, an oscillation circuit starts it's oscillation operation by the inherent resonance frequency of a resonator. After that, as the cut of the variable power source is canceled when the supply voltage reaches the prescribed value, the frequency according to variable reactance is oscillated by the current change of the variable power source. As the variable power source of the variable reactance circuit is operated after the oscillation operation by the inherent frequency of the resonator is stabilized in that way, the oscillation unstarting or the abnormal oscillation of the oscillation circuit caused by the variable reactance circuit can be prevented.

Abstract: PURPOSE:To improve both the stability and the operability with smooth movement of a machine by increasing the manual command shift speed up to a fixed speed in accordance with the input time of a manual shift command, then changing the manual shift speed in a manual shift state. CONSTITUTION:When an input switch 9 of a manual command input means is turned on, a switch output signal A of an H level is inputted to a terminal S of a ramp waveform output circuit 14 as well as to a rise differentiation circuit 13 respectively. The circuit 14 starts its operation at rise of the signal A and sends the ramp voltage C having a fixed slope to a clamp circuit 15 in proportion to the duration of an ON state of the switch 9. The voltage C is continuously sent to a V/F converter 12 until the voltage C reaches the level of the voltage V15. The frequency of a command pulse train E is gradually increased during a time T when the voltage C is sent to the converter 12. When the voltage C reaches the level V15, a command pulse train of a fixed frequency is outputted to a CPU. Then a machine moves gradually when the switch 9 is turned on, and the low shift speed of the machine is changed to a high shift speed.
