Title: Transistor inverter
Inventor: HARA TAKAHIRO
IPC: H02M3/338
Filed: 1981-02-07
Abstract: PURPOSE:To improve the efficiency of a transistor inverter by providing a capacitor which is charged by a power source through a large resistance value and supplying as a drive current the charging charge to a transistor at the time of starting an oscillation, thereby reducing the power loss. CONSTITUTION:A pair of transistors 7, 8 are alternately conducted to generate an AC output at a power transformer 6, and the output of the feedback coil N5 of a transformer 6 is rectified by a rectifier 15 to drive the respective transistors 7, 8. A large resistance resistor 18 and a capacitor 18 are connected to a power source, the charging charge of the capcitor 19 is fed as a drive current through a voltage firing thyristor 20 at the time of starting the oscillation. Accordingly, when the chrge of the capacitor 19 becomes higher than the breakover voltage of the thyristor 10, the oscillation is started by the discharge, and the oscillation is continued thereafter by the current of the feedback coil N5. Therefore, the efficiency can be improved by eliminating the loss of the starting resistor.

Title: Polarizer
Inventor: INOUE NAOHISA
IPC: G02F1/295
Filed: 1983-02-05
Abstract: PURPOSE:To obtain an excellent polarizer using a substrate of glass or polymer material by forming an optical waveguide whose refractive index is changed by temperatures on a substrate and then forming a diffraction grating containing the heat generating and non-heat generating parts alternately with a prescribed space on said optical waveguide. CONSTITUTION:An optical waveguide is formed with a glass plate or polymer material whose refractive index varies by temperatures. For instance, a glass slide plate 2 is dipped into a silver intrate-dissolved salt to obtain an optical waveguide 3 containing diffused Ag<+>. A diffraction grating 4 having heat generating parts 4a and heat absorbing part 4b formed alternately is formed on the waveguide 3 by a lift-off process of Ti, etc. A power supply 5 is connected to both ends of the part 4a to heat up the part 4a. The incident light P goes straight when the part 4a is not heated and then deflected in the form of the reflected light Q when the part 4a is heated. For instance, the refractive index change DELTAn/DELTAT is set at about 1X10<-5> with the rise of temperature by 1 deg.C and the parts 4a and 4b are set at 100 deg.C and 70 deg.C respectively. Therefore the refractive indexes of the parts 4a and 4b vary like waves with a 20mu pitch, and the difference of refractive index is set at 3X10<-4> to ensure the assured polarization.

IPC: F24J2/04
Filed: 1981-02-10
Abstract: PURPOSE:To prevent the temperature within a heat collecting casing from being lowered owing to the air introduced in the casing by a method wherein an outside air guide pipe, which is connected to an outside air opening and as well as provided with an opening for discharging the outside air at the lower part of the casing, is provided within the casing. CONSTITUTION:The outside air guide pipe 5 is arranged on a flat plate lath 7 placed on heat accumulating elements 4.

The both open ends of the pipe 5 are collected by means of a manifold and open to the outside through the outside air opening 12 of the casing 1 for intake of the outside air. Because there is a fear that if the low temperature outside air is introduced without deep thoughts from the outside air opening into the casing 1 said air is diffused so as to cool the inside air heated with much labors, the outside air guide pipe 5 serves to guide the outside air in the fixed flow passage in order to prevent the air from diffusing and as well as to give the air a certain ectent of preheating effect by flowing within the pipe 5 and, after that, to diffuse in the casing 1 for heating the inside air.

Title: Production of cured epoxy resin product
Inventor: KAGA YUKARI
IPC: C08G59/18
Filed: 1989-01-27
Abstract: PURPOSE:To make it possible to obtain a cuerd product even under conditions in which heating is not possible by heating a mixture of an epoxy resin with an acid anhydride or at least either of the components before mixing, cooling it to ordinary temperature, adding a cure accelerator to the mixture at any desired time and curing the resulting mixture at ordinary temperature. CONSTITUTION:An epoxy resin (e.g. bisphenol A/epichlorohydrin epoxy resin) is cured with an acid anhydride (e.g. methylbutynyltetrahydrophthalic anhydride) in such a way that a mixture of the epoxy resin with the acid anhydride or at least either of them before being mixed is heated and cooled to ordinary temperature, a cure accelerator is added to the mixture at any desired time, and the resulting mixture is cured at ordinary temperature. Because the heating step and the curing step are separate, a cured product can be obtained even under conditions in which heating is not possible. Therefore, it can be used for various fields such as bonding and lining heretofore not developed, and because it is highly reactive and can be sufficiently cured with water, it has a possibility of use under conditions in which curing is performed even in the presence of added water.
