Patent JP-S6488070-A (JP)
Title: Reactor
Inventor: IKEUCHI MASAKI
IPC: F25B17/12
Filed: 1987-09-28
Abstract: PURPOSE: To accelerate reaction and heat transfer by dispersing a first reactive substance into a disperse medium and discharging vapor of a second reactive substance into the disperse medium thereby improving contact and stirring of the first and second reactive substances. CONSTITUTION: Cooling water is fed from a cooler 20 to a first heat exchanger 4 in order to start productive reaction. A reactive substance A9 and a disperse medium 10 are cooled and a reactive substance B11 is evaporated in a second container 13 to generate cold heat being used for a freezing load 21. Vapor of B11 is passed through a vapor flow-in passage 15 and ejected from a vapor header 12 into the medium 10 where it reacts on the A9. Reaction heat is treated by the cooler 20 through the heat exchanger 4. On the other hand, the medium 10 is cooled to evaporate a part of dissolved B11 and the disperse medium 10 is stirred thus improving contact of A9 and B11 and accelerating reaction and heat transfer.

Filed: 1989-09-18
Abstract: PURPOSE:To obtain image quality with stable gradations at all times irrelevantly to the rest of toner by detecting the torque of an agitator and adjusting the bias voltage of a developing roller automatically according to the rest of toner. CONSTITUTION:Single-component toner is agitated by the agitator 30 in the hopper 29 of a developing unit 18 and supplemented to a developing roller 32 by a supplementing roller 31, and the toner on the developing roller 32 is layered thinnly with a blade 3 and carried onto a photosensitive body to perform development. The developing roller 32 and supplementing roller 31 are applied with voltages which have a certain constant potential difference and when the input voltage Vi to the supplementing roller 31 varies, the bias voltage Vb to the developing roller 32 also varies. This bias voltage Vb is adjusted automatically according to variation of the torque of the agitator 30. Namely, a detecting device 35 detects the torque of the agitator 30 as an electric signal and a bias voltage control circuit 36 controls a variable bias unit 37 according to the torque quantity to adjust the input potential Vi. Thus, the bias voltage Vb of the developing roller 32 is adjusted automatically according to the rest of toner.

Title: Fusion cutting method for concrete by laser beam
Inventor: KUTSUMI AKIRA
IPC: B23K26/16
Filed: 1986-10-13
Abstract: PURPOSE:To assure the depth of fusion cutting by projecting plural pieces of laser beams at a specified width on both sides of the fusion cutting line of concrete to melt the concrete and to expel the molten concrete to the lateral and lower side of the fusion cut groove. CONSTITUTION:Three pieces of the laser beams 12a, 12b, 12c are projected within the specified width W on both sides of the fusion cutting line 16 of the concrete. The respective beams are disposed to deviate by a distance (t) each in the perpendicular direction at every distance (s) in the progressing direction and are partly superposed by each part; in addition, the beams are so projected that the melting circles of the 1st, 3rd beams 12a, 12c contact the outside end of the specified width including the fusion cutting line 16. The formation of the unmolten part of the concrete within the specified width W is prevented by the above-mentioned method and, therefore, the molten concrete is expelled laterally and downward without being clogged in the fusing cut groove 18. The depth of the fusion cutting corresponding to the beam energy is thus assured.

Title: Semiconductor laser device
Inventor: MURAKAMI TAKASHI
IPC: H01S5/24
Filed: 1983-12-19
Abstract: PURPOSE:To reduce the generation of growing failures by growing a fundamental layer which is easy for crystal growth and subsequently a lower clad layer before growing the lower clad layer on a current narrowing layer in which a striped groove is formed. CONSTITUTION:On a current stricture layer 2 in which a groove 3 is formed, a lower clad layer fundamental layer 11 is grown, after which a lower clad layer 4 is formed on that layer 11. At this time, a mixed crystal ratio of Al of the lower clad layer fundamental layer 11 is made to be smaller than that of the lower clad layer 4. A thickness of the fundamental layer 11 is so determined that the groove 3 is not buried by the layer 11 completely. It is difficult to liquid-phase grow the layer of a large mixed crystal ratio of Al like the lower clad layer 4 directly on the current narrowing layer 2 without a defect, but growth of the lower clad layer fundamental layer 11 of reduced mixed crystal ratio of Al is easier as compared with the above case and a growing failure is hardly produced. As the lower clad layer 4 is grown continuously on that lower clad layer fundamental layer 11, there is almost no growing failure between the layers 11 and 4.

Title: Photodetector
Inventor: SUDO HAJIME
IPC: H01L27/146
Filed: 1989-09-19
Abstract: PURPOSE:To perform coupling electrode wiring suitably for photodetectors which are disposed quite densely by forming an insulating film on coupling electrode wiring and forming the photodetectors on each opening of the insulating film and a substrate. CONSTITUTION:A piece of common coupling electrode wiring 11 is formed by traversing each lower part of a plurality of photodetectors 13 and respective photodetectors 13 are formed on coupling electrode wiring 11 through each opening 12a. Consequently, it is enough for coupling electrode wiring to perform its wiring only on a semiconductor or insulating substrate 10 without installing coupling electrode wiring at grooves which are made after performing element isolation. Coupling electrode wiring 11 is thus formed without being affected by a space between adjacent photodetectors.
