Patent JP-H01276689-A (JP)
Title: Semiconductor laser device
Inventor: TANAKA TOSHIO
IPC: H01S5/00
Filed: 1988-04-27
Abstract: PURPOSE:To stabilize the laser oscillation from a low current injection region through a high current injection region by a method wherein an active layer is bent by an AlGaAs growth blocking layer and a GaAs selective growth layer and the active layer is provided between both the end parts of the AlGaAs layer having a small refractive index and, further, end surface window structures made of AlGaAs having a wider forbidden band width than the active layer are provided at the end surface parts of a resonator. CONSTITUTION:A GaAs layer 3 is left on the part of a substrate 1 where an active region necessary for layer oscillation is formed beforehand and an AlGaAs layer 4 is exposed on the remaining parts. As a result, steps are provided between the necessary active region and the other parts. With this constitution, as a light and a current can be efficiency confined only in the laser oscillation region of the active layer, a stable lateral mode oscillation can be realized from a low current injection region through a high current injection region. Further, as a P-type GaAs active layer 5 is bent at the end surface parts of a resonator and replaced by AlGaAs layers having a wide forbidden band width, the end surface breakdown can be avoided.

Title: Production of color filter
Inventor: TAKEYAMA KENICHI
IPC: G02F1/1335
Filed: 1983-06-15
Abstract: PURPOSE:To improve accuracy of a pattern for filter and to prevent the spreading of a pattern edge by coating a material which absorbs the light of the wavelength shorter than the wavelength of a visible light region on the part under a dyed layer thereby preventing reflection from a base plate. CONSTITUTION:A material formed by kneading a UV absorbent such as a compd. having absorption at 300-400nm, for example, of benzophenon, salicylate or benzotriazole is coated on a glass base plate 8 as an absorbent layer 9 for decreasing the reflection from the base plate. The reflection from the lower layer in the stage of producing a color filter is prevented by the absorbent curtain 9, by which the fluctuation in an exposing condition in the stage of forming the upper layer is suppressed and the manufacturing condition is stabilized.

Title: Hermetic cathode-supporting member for electron gun
Inventor: KAWAMURA KEIYOSHI
IPC: H01J1/20
Filed: 1980-08-06
Abstract: PURPOSE:To increase the sticking strength of adhesion interfaces, and thereby enhance the reliability of a hermetic cathode-supporting member by insulating and supporting cathode supports by means of a crystalline glass, which shows approximately the same expansion coefficient as the cathode supports between a shifting point and a yield point, and has an increasing expansion coefficient instead of yield beyond the yield point. CONSTITUTION:A container 6 having a rectangular cross section is packed with an insulator 7 made of crystalline glass, which serves for insulating and supporting three cylindrical cathode supports 5 each having a cathode at its end. The supports 5, which are linearly placed in the container 6, are integrated with the body 6 into an in-line shape. The insulator 7, since it is made of an Fe-Ni alloy such as 42Ni-Fe alloy having a large heat expansion factor, adheres at high temperatures. The cathode supports 5, the thermal expansion coefficient of which is adjusted to be approximately the same as that of the insulator 7 between a room temperature and a fixing point, are made of an Fe-Ni-Co alloy such as Kovar. As a result, since the insulator 7 doesn't flow at high temperatures, sufficient sticking strength of the adhesion interfaces is obtainable.

After solidification, cooling is further performed through the temp. region from 1300 to 900 deg.C at >=100 deg.C/sec cooling rate, by which a cast strip of 0.7-3.0mm thickness is prepared. This cast strip is annealed, cold-rolled at >=80% final draft once or twice or more times while process- annealed between the cold rolling stages, and further subjected to decarburizing annealing and to finish annealing. By this method, the grain-oriented silicon steel sheet having high magnetic flux density, having an extremely high degree of integration in the (110) <001> orientation, and excellent in magnetic properties can be obtained while obviating the necessity of hot rolling.

Title: Reset control device for digital circuit
Inventor: KATO HITOTSUGU
IPC: G06F1/24
Filed: 1992-04-27
Abstract: PURPOSE:To simplify the adjustment of a control circuit and to suppress the size increment of hardware in the case of executing control for preventing the generation of malfunction by holding a digital circuit at a reset state until the oscillation state of an operation clock is stabilized at the time of turning on a power supply. CONSTITUTION:When a RESET next step signal outputted from an inverter 216 is raised to a high level at the initial start of the power supply, an F/F 208 is set up and a RES2 signal is turned to a high level. The high level RES2 signal interrupts the address specifying operation of a ROM address control part 105. Even after decaying the RESET next step signal to a low level, a counter consisting of latches 210, 211 executes count-up operation and the RES2 signal is held at the high level during the period of abount three operations until the SK signal is raised to a high level. Thereby, timing control for stabilizing operation at the initial start of the power supply can be attained. The counter consisting of the latches 210, 211 is used also for timing control for the stabilization of operation at the time of turning on the power supply switch again after turning off it.

Title: Gun for capacitor discharge type stud welding machine
Inventor: NAKAMAE FUJIO
IPC: B23K11/26
Filed: 1981-07-09
Abstract: PURPOSE:To reduce the capacity of a capacitor by flowing electric current to a coil to attract a ferromagnetic material thereby controlling the pressure upon the work in the welding stage. CONSTITUTION:When a switch 16 for starting of welding is pushed, electric current flows through a cabtyre cable 18, a stud 1 and its projection 2, and the arc is generated in the part of the projection 2. At the same time, a magnetic field is created by a coil 11, by which the force trying to pull a plunger 10 which is a ferromagnetic material into the center of the coil 11 is generated. Since this force is in the direction opposite from the force of a spring 9, the plunger can be virtually stopped during the generation of the arc if the spring 9 of a proper force is selected. On stopping of the position of the stud 1, the arc spreads further circumferentally and in accordance with the completion of the discharge by a capacitor to certain extent, the electromagnetic forces  diminish and the force pressing the stud 1 to the work 19 increases, thus welding both more firmly.
