Title: Guidewave type second harmonic generating element
Inventor: KAWAMOTO KAZUTAMI
IPC: G02F1/377
Filed: 1991-12-25
Abstract: PURPOSE:To enable generation of the second harmonic where the efficiency is high, the wave aberration is small, and the converging is easy by periodically inverting the nonlinear optical coefficients of both one part of a substrate and a an optical wave guide layer. CONSTITUTION:In an optical element consisting of an optical substrate 14 and an optical wave guide layer 16 whose refraction factor is larger than that of the substrate 14, the nonlinear optical coefficients of both the optical substrate 14 and the optical waveguide layer 16 are periodically inverted. For example, in the optical element consisting of ZcutLibO3 monocrystal substrate 14 of 5 mol% MgO dope where the surface is +C, and LiNbO3 monocrystal substrate 16 of 1mol% MgO dope, the spontaneous polarization is normally faced upward while it is faced downward in the parts 15, 17 where the polarization is inverted. The sign of the nonlinear optical coefficient coincides with the direction of the spontaneous polarization in the case of the ferroelectric substance crystal of the space group R3c of LiNbO3, LiTaO3 or the like. Thus, the nonlinear optical coefficients of the substrate 14 and the light guide layer 16 are also periodically inverted.

Abstract: PROBLEM TO BE SOLVED: To reduce an attaching sound without using any friction materials by setting the holding force of an armature plate by a rubber damper to be non-uniform in a circumferential direction, making a colliding and joining time when the armature plate is adsorbed on a rotor long and reducing collision energy.

When current is carried to an exciting coil in this condition, an armature plate 10 is attracted and joined to rotor friction by the rubber damper having weakest rubber damper compression deflection margin, for instance the rubber damper 18-1. Then, it is attracted and joined to the second weakest rubber damper 18-2 and, lastly, it is attracted and joined to the strongest rubber damper 18-3. Thus, an attracting and joining time is made longer than when all the rubber dampers have uniform compressing deflection margin and collision energy and an attracting sound is reduced.

IPC: H01L29/78
Filed: 1992-12-25
Abstract: PURPOSE:To provide the matrix substrate which eliminates the possibility of electric corrosion of electric wirings and ion transfer and lowers the resistance of electric wirings. CONSTITUTION:This matrix substrate is constituted by isolating source wirings 13 and pixel electrodes 15 on an insulating substrate by gate insulating films 6 and lower source wirings 12 formed on the upper layer of the gate insulating films 6.
