Title: Gas laser device
Inventor: TERAI KIYOHISA
IPC: H01S3/038
Filed: 1988-06-10
Abstract: PURPOSE:To prevent the deterioration of a discharge tube to the utmost so as to lengthen a maintenance period by a method wherein a discharge igniting region surface of one of discharge electrodes is formed of titanium oxide. CONSTITUTION:Even if a cathode 3 is subjected to a sputtering action through a discharge, as the surface of the discharge lighting region is covered with a titanium oxide thin film 7 extremely low in a sputtering rate, a sputtering amount itself is extremely small. And, titanium oxide is a very stable material and its vapor pressure is very low, and a chemical sputtering hardly occurs. Therefore, the amount of the deposit on an anode 2 is remarkably decreased as compared with a conventional method that a molybdenum cathode is used, so that the concentration of an electric field on the surface of the anode 2 and also a microarc can be prevented from occurring by that extent. And, as the titanium thin film 7 is stable, the concentration of an electrical field on the surface of the cathode due to an unequal sputtering, which occurs in a conventional molybdenum cathode, is almost prevented, and the generation of a microarc can be restrained also by that fact.

Title: Surface light emitting semiconductor laser
Inventor: IGA KENICHI
IPC: H01S5/10
Filed: 1982-08-20
Abstract: PURPOSE:To prevent the production of roughness of an electrode mirror surface due to heat treatment by isolating a reflection mirror surface from an electrode. CONSTITUTION:A disc mirror surface region 7c at the center of a ring-formed junction region 7b contacts P-InP layer 5 via an insulation layer 6. When a drive current flows into the electrode 8 from its ring-formed junction region 7b, an active region 10 is formed in a CaInAsP layer 4 by a stricture current. But, a Fabry-Perot resonator is formed between the disc mirror surface region 7c at the center of the ring-formed junction region 7b and the mirror surface of a Au film 9, and accordingly a laser oscillation 11 generates there. The light by this laser oscillation is emitted to the vertical direction as shown by the arrow 12 in the same manner as convention. Since the disc mirror surface region 7c of Au/Zn is isolated from the P-InP layer 5 by the insulation layer 6 of SiO2, etc., the fusion of Au/Zn with In generated at the ring-formed junction region at the time of annealing treatment is prevented by the SiO2 layer on the mirror surface 7c, and accordingly an excellent state of mirror surface of high reflectance can be maintained.

Title: Preparation of thermal recording material
Inventor: FUJII YUICHIRO
IPC: B41M5/337
Filed: 1988-06-10
Abstract: PURPOSE:To obtain high-grade image quality at the time of recording while imparting mirror surface gloss to the surface of a recording layer without lowering whiteness by containing protein in a thermal recording layer in a specific ratio with respect to a total solid and setting the temp. of a metal drum to a specific range to apply casting finish to said layer. CONSTITUTION:Protein is contained in the final coat layer of a thermal recording material in an amount of 0.5-40% by wt. of the solid of a thermal recording layer. By this method, the thermal recording material wherein release property improving effect is obtained and high gloss and high image quality are obtained continuously and stably can be prepared. At this time, when the content of protein is 0.5wt.% or less, release effect is insufficient and a continuous operable time is short and, when said content is 40wt.% or more, the recording sensitivity of the thermal recording material is markedly lowered. The drying temp. of a metal drum is desirably adjusted to a range of 30-110 deg.C in usual. When the drying temp. is 30 deg.C or less, since drying function is poor even when the thermal recording paper on a cast drum is auxiliarily dried from the rear thereof by a hot air dryer and the close adhesiveness to the metal drum is not uniformly performed, uniform mirror surface gloss is hard to obtain and, when said temp. is 110 deg.C or more, color reaction is generated from a material surface in many cases.

Title: Semiconductor memory device
Inventor: MATSUMURA MASASHI
IPC: G11C11/413
Filed: 1995-06-12
Abstract: PURPOSE: To develop a semiconductor memory device which can be operated stably even when a power supply to the semiconductor memory device is a low voltage so as to correspond to the low voltage of a power-supply voltage to a semiconductor integrated circuit device which contains the semiconductor memory device. CONSTITUTION: A boosting circuit 21 which boosts the potential of power supplies 13 is connected across bit-line loads 14 at the inside of a semiconductor memory device and the power supplies 13 to bit lines. Alternatively, instead of the boosting circuit 21, a power supply which is different from a main power supply supplied from the outside of the semiconductor memory device and which has a potential higher than the potential of the main power supply is used as a power supply which directly supplies a potential to the bit-line loads 14. By this constitution, the amplitude of bit lines can be constituted so as to be set up to a potential which becomes higher than the potential of the power supply to the semiconductor memory device. Consequently, the stability of a memory cell can be increased at the low voltage of the power supply.
