Title: Production of liquid crystal display panel
Inventor: ARAI KAORU
IPC: G02F1/13
Filed: 1984-07-24
Abstract: PURPOSE:To form a liquid crystal layer to have a more uniform thickness by pressing a pair of substrates surfaces which are sealed at the peripheral part in a manner as to have a uniform gap on the display surface of a panel and injecting a liquid crystal into the panel in this state. CONSTITUTION:Two sheets of the glass substrates 1 on which electrode patterns 2 are formed are pressed uniformly by smooth plates via spacers 3 in such a manner that the pattern sides face each other. The peripheral part of the substrates 1 is sealed under heating by a thermosetting resin. The substrates 1 are then sandwiched by a frosted sheet glass 8 and are pressurized by springs 6 to conform to the spacers 3. The inside of the panel is evacuated to suck the liquid crystal 5 to the inside of the panel and thereafter the liquid crystal injecting hole is sealed. Therefore even if the substrates are going to restore the original curved state, the substrates 1 are attracted to each other by the internal negative pressure. The gap is thus maintained and the uniform liquid crystal layer is maintained by the spacers 3. The production of the panel which obviates uneven display at a high yield is made possible.

Abstract: PURPOSE:To stably obtain a gimbal spring with high springiness having a corrosion resistant beautiful golden color coating in a good yield in a simple process, by applying heat treatment to a stainless base material in an oxidative atmosphere at a specified temp. for a specified time. CONSTITUTION:A stainless base material such as SUS304 is punched into a spring shape and the punched object is subjected to annealing treatment in an electric furnace.

Abstract: PURPOSE:To turn OFF power supply for AC primary circuit upon turn OFF of power switch on electric machine side by providing a switching means for electrically turning ON/OFF the AC primary circuit in response to ON/OFF operation of the power switch of the electric machine. CONSTITUTION:An AC adapter 1 is connected through a connector 5 with an electric machine 3 and power is fed from the AC adapter 1 to the electric machine 3. The AC adapter 1 feeds AC power to a transformer T through a plug 7 connected with an AC power supply. AC primary input voltage to the transformer T is transformed into a desired secondary voltage. The transformed voltage is rectified through a rectifying diode D1 and then ripple is removed therefrom through a smoothing capacitor C1 thus feeding a smoothed DC voltage to a three terminal regulator 9. The regulator 9 stabilizes the DC output voltage. The stabilized voltage is further fed through a reverse-blocking diode D2 to the relay 15 of the electric machine 3 thence through a switch 15B to a terminal 2.

IPC: H01S5/00
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser element for stabilizing laser characteristics by eliminating dispersion in the height of a step part, and its manufacturing method. SOLUTION: When a step part 36 is formed by etching a contact layer 30, progress in etching for an upper clad layer 26 is stopped by an etching stop layer 28 that is formed on the entire upper surface of the upper clad layer 26. Therefore, by setting the etching time to be longer and completely eliminating the thick part of the contact layer 30 through etching, the height of the step part 36 is made uniform at the same height as the thickness of the contact layer 30, thus dispersion in the height of the step part 36 is eliminated, and laser characteristics is stabilized and preventing reduction in yield is prevented.

IPC: G05F1/00
Filed: 1981-09-30
Abstract: PURPOSE:To prevent other circuits from malfunctioning when one circuit is connected or disconnected, by preventing the power voltages of other circuits from varying. CONSTITUTION:The voltage variation absorbing circuit consisting of a diode 3 and a coil 4 connected in parallel is connected in series to a load circuit 6, and a capacitor 5 is connected in parallel to the load circuit 6. Thus, the coil 4 and capacitor 5 are added to make voltage variation slow, and consequently a voltage applied to the load by an excessive current generated by the characteristics of the coil 4 rises, so it is fed back to the power source side through the diode 3 to apply the load with a voltage having less variation.
