Patent JP-S6364377-A (JP)
Title: Laser oscillator
Inventor: USUI AKIRA
IPC: H01S3/036
Filed: 1986-09-04
Abstract: PURPOSE:To reduce the damage of a reflecting mirror due to the adhesion of dust by mounting a cylindrical member inside the reflecting mirror resonating laser beams and forming a clearance between the nose of the cylindrical member and a duct nose positioned on the extension of the cylindrical member. CONSTITUTION:A side flow flowing through a side flow duct 17, a communicating member 18 and the outer circumferential surface of a duct 16 is guided by a clearance delta, passes in the duct 16 and is circulated to the discharge side. The greater part of the side flow flowing in from the clearance delta are circulated to the discharge side at that time, and only a small quantity of them reach to the reflecting mirror 1 side. Consequently, the retention of a gas in the vicinity of the reflecting mirror 1 is removed by one part of the side flow though only a small quantity of them reach, thus preventing the temperature rise of the gas. Since only a small quantity of the side flow reach to the reflecting mirror 1, dust with the side flow is generated in a negligible quantity, thus largely making adhesion to the reflecting mirror of dust smaller than conventional devices. Accordingly, the damage of the reflecting mirror 1 can be reduced sharply, thus stabilizing the performance of a laser oscillator.

IPC: G01R27/02
Filed: 1989-08-11
Abstract: PURPOSE:To enable highly-precise measurement of a contact resistance value of a wide range at a prescribed current value by separating analog and digital circuits electrically by using a photocoupler, and by displaying the result digitally. CONSTITUTION:Being controlled by a digital drive circuit 1, a prescribed current is supplied from a constant current circuit 3 to a contact 10 to be measured and a measured voltage proportional to a resistance value of the contact 10 is amplified 4, subjected to A/D conversion 5 and displayed digitally in a display element 9, while determination of the quality in respect to a reference value is displayed in a determination display element 8. On the occasion, transmission of signals between an analog signal system of the circuit 3, a differential amplifier 4, etc. and a digital circuit such as the circuit and a comparator circuit 7 is executed optically by photocouplers 2 and 6. Thereby it is made possible to separate electrically the two circuit systems from each other and to separate a power source and the earth completely. Accordingly, the lowering of precision in measurement due to the superposition of a commercial frequency, switching noise, impulse noise or the like on an analog signal is eliminated and highly precise measurement can be executed with a prescribed measuring current.
