Title: Fault monitoring method for arithmetic circuit
Inventor: IDE SHOTARO
IPC: H04L47/22
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To easily use a method in common to polishing and shaping without depending on algorithm with a small hardware scale by using an OH generation cell which is periodically generated at the time of converting an ATM cell format into a format in a device from the format of a transmission line. SOLUTION: Parameters for monitoring OH(overhead) generation cell are previously set for respective memories 42-45 and 401. A header detection part 40 identifies the cells. In the case of the OH generation cell, an OH generation cell period monitoring part 400 monitors an arriving period. When it is a regulated period, the parameters for OH generation cell are sequentially read from the respective memories 42-45 and 401 and the fault is monitored. When a polishing operation is executed and the cell is judged to be illegal in a conformity test and when a cell interval after shaping is not similar to that of the cell, it is judged that abnormality occurs in the arithmetic circuit. Thus, the increase of a circuit scale is small and miniaturization can be executed.

Title: Laser beam machine
Inventor: FUJISHIRO MASAHARU
IPC: B23K26/066
Filed: 1992-11-30
Abstract: PURPOSE:To improve the transfer efficiency without manufacturing deffective products by immediately stopping the emission of the laser beam when the pattern information transfer is deviated. CONSTITUTION:The desired pattern information is displayed on a liquid crystal mask 15 from an operation control part 2 of a laser beam marking equipment. The laser beam 11A from a laser beam oscillator 10 passes through the plane of polarization of the liquid crystal mask 15 and transfers the desired pattern information on a work 13. When a sensor 26 to detect the position of the work 13 on a conveyor 25 senses the deviation, a motor 23 of the conveyor 25 is controlled by the judgement of a carriage control part 24. At the same time, the signal to detect the deviation opens a laser beam power source switch 20, and opens the control switch of an AND circuit 10C. This constitution prevents the transfer of the work 13 from being produced without correcting the positional deviation.
