Patent JP-S61226928-A (JP)
Title: Vapor-phase etching method
Inventor: YAJIMA YUSUKE
IPC: H01L21/302
Filed: 1985-04-01
Abstract: PURPOSE:To enable the implementation of a processing at a lower temperature by a method wherein an irradiating light is made incident aslant on the surface of a substrate and, moreover, the direction of polarization of the irradiating light is so designed that it can be set to be vertical or parallel to a plane of incidence so that an angle of incidence and the direction of polarization may be selected to be on specified conditions as occasion calls. CONSTITUTION:Since an incident light 2 and reflected light 6 are in accord with each other in terms of both wavelength and frequency, the time average of an optical intensity is to have a distribution dependent periodically only on the distance from a substrate 1 as the result of the interference of the incident light 2 and the reflected light 6 on the surface of the substrate 1 in the case when the incident light 2 is regarded as a plane wave. The amplitude, period, phase and central value of this periodical distribution are determined by the complex index of refraction of the substrate 1 in the frequency of the incident light 2, the wavelength and the direction of polarization of the incident light 2, and an angle of incidence theta thereof. Even when the wavelength of the incident light 2 and the quality of the material of the substrate 1 are identical, the distribution of the optical intensity on the surface of the substrate 1 is varied by changing the angle of incidence theta and the direction of polarization of the incident light 2.

IPC: H01H50/32
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To reduce cost and to prevent impact force of an iron core and wear and damage of an attraction surface by driving a switch by small electromagnetic force by assisting driving force of a movable part by reversal of a reverse spring when the movable part is moved in a direction that a contact is closed and rotating the reverse spring when the movable part is moved in a direction that the contact is opened. SOLUTION: When voltage is applied on a coil 12, a movable iron core 9 and a cross bar 1 are moved by electromagnetic attraction.

When voltage of the coil 12 is switched off, electromagnetic attraction is extinguished and the cross bar 1 is moved in a separating direction by restoring force of a separating spring 14.  The tip part 15a is moved from the recess bottom surface 19b of the cross bar 1 to a recess side surface, the reverse spring 15 is rotated around a shaft 17, force of the attraction direction is reduced by restoring force, and electromagnetic attraction closing the iron core 9, that is, power is reduced.
