Title: Laser beam machine
Inventor: IIDA FUMIO
IPC: B23K26/00
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent dust of spatters or the like from sticking to an optical system member and also to reduce the fluctuation of the focal position of the optical system member due to heat of an assist gas and a high output of laser beam during laser machining. SOLUTION: The laser beam LB oscillated into a laser machining head 9 part from a laser beam oscillator is condensed with a condensing lens 13 (optical system member). This condensing lens 13 is protected with a filter 25 in the airtight chamber 29 formed in the optical path of the laser beam. Even though the condensing lens 13 generates heat during laser machining, since the temperature within the airtight chamber 29 is regulated to cool the condensing lens 13 and the pressure within the airtight chamber 29 is regulated, the focal position of the condensing lens 13 is not deformed even though the pressure of the assist gas 19 fluctuates, whereby stable laser machining is obtained. Even though dust of spatters or the like invades into the laser machining head 9, the condensing lens 13 is protected with the filter 25.

Abstract: PURPOSE:To make it possible to prevent a decrease in breakdown strength due to the intersection of an electrode for contact led out to the outside of an isolated island and a first conductivity type high impurity concentration region, by installing a plurality of floating electrodes in a lower insulating layer at intervals in the conditions that the floating electrodes are wider than an electrode for second conductivity type semiconductor region and are projected out from the electrode. CONSTITUTION:In an insulating layer of the lower of an electrode 11 for p-type region 6, a plurality of floating electrodes 18, 18,... made of polysilicon are installed in the extending direction of the electrode 11 at intervals. Each floating electrode 18 is formed in the conditions that each floating electrode 18 is wider than the electrode 11 and is projected out from the electrode 11. Even if the intersection state of the electrode 11 for p-type region 6 and an electrode for n<+>-type region 13 not eliminated, a necessary electric field relaxation action is implemented when a voltage is applied so that the electrode 11 has a negative potential. As a result, an electric field distribution between the p-type region 6 and the n<+>-type region 13 directly below the electrode 11 in which an electric field is relaxed is made uniform and the breakdown strength is improved.
