Title: Optical switch
Inventor: SHIRASAKI MASATAKA
IPC: G02F1/09
Filed: 1981-04-09
Abstract: PURPOSE:To drive an optical switch easily by a small magnetic field by using a 45 deg. Faraday rotator thin plate with a phase matching film and a 45 deg. rotary polarizer in combination as a polarization plane converting element. CONSTITUTION:Incident light beams 1 and 2 are separated by a polarizing and separating element 3, and the transmitted and reflected beams are passed through Faraday rotators 4 and 4' to rotate their planes of polarization by +45 deg. or -45 deg.; and they are passed through 45 deg. rotary polarizers 5 and 5' to further rotate the planes of polarization by 45 deg., and then caused to illuminate wedge- shaped polarizing and separating elements 6 and 6' which reflect two orthogonal polarized beams in slightly different directions. Since the reflected light beams pass through the 45 deg. rotary polarizers 5 and 5' and 45 deg. Faraday rotators 4 and 4', they are polarized light beam crossing the original light beams at right angles. Therefore, the light 7 from the rotator 4 is transmitted and the light 8 from the rotator 4' is reflected, eliminating polarization dependency. The magnetization of the Faraday rotators is inverted, and thus the switching of luminous flux to A or B is possible.

Title: Evaluation of reliability of insulating film
Inventor: YONEDA KENJI
IPC: G01R31/12
Filed: 1990-03-05
Abstract: PURPOSE:To make it possible to measure precisely the amount of injected charge to be required up to a time to reach a dielectric breakdown of an insulating film in a short time and at a wide dynamic range by a method wherein the duty ratio (a pulse width) and repeating period of a current pulse are set constant and each time the digit of the amount of the injection charge is increased by one digit, a stress current is increased by 10 times and is applied. CONSTITUTION:A pulse of 0.1 second is applied in a current density of 10<6>A/cm<2>. After that, an electric field of 2MV/cm<2> is immediately applied and in case a current flows in a current density of 1muA/cm<2> or higher, the phenomenon is judged as the generation of a dielectric breakdown. Here, in case the dielectric breakdown is not generated, an application of pulses is successively repeated. After that, 100 pulses in total are applied in the above current density up to a time to reach the breakdown. After the application of the pulses, the amount of injected charge reaches the amount of 10<-4>C/cm<2>. Therefore, the stress current density is made higher by one digit here, is set in a current density of 10<-5>C/cm<2> and a measurement identical with the above one is conducted. However, the number of applying pulses is reduced to 99 from this time on. When the application of all the 99 pulses is finished in the above current density, the amount of injected charge reaches the amount of 10<-3>C/cm<2>. In case the dielectric breakdown is not generated even at this amount, the current density is made higher in order one digit by one digit and an increase in the current density is continued up to a time to reach the dielectric breakdown. In this case, the upper limit of the stress current density this case is 1A/cm<2>.
