Title: Quantum box structure provided with current constriction structure and forming method thereof
Inventor: MIYAZAWA SEIICHI
IPC: H01S5/34
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To realize a current injection mechanism capable of feeding a current to a quantum box region separately formed at the center of a semiconductor by a method wherein the semiconductor is so processed as to be changed in P/N polarity in the lateral direction of lamination to enable a current to flow through only a required semiconductor film. SOLUTION: A semiconductor film 7 for blocking a current is grown on a region 2 on a substrate 1 surrounded with a periodic structure layer 4 and an SiO2 film 3 and set different in polarity from lower layers 4 and 1, then the SiO2 film 3 is removed, and a layer 8 of the same conductivity with the substrate 1, a layer 9 which contains impurities of P and N-type, and a layer 10 of the same conductivity with the substrate 1 are laminated. Then, the layers 4, 7, and 8 of the region 2 are made to serve as a current block layer for a quantum box formed on the region 3, then a layer 11 which contains a quantum box serving as an active layer and a layer 12 opposite in polarity to the substrate 1 are successively laminated for realizing a current constriction structure.  Therefore, a current is made to flow through only a quantum box laminated on the surface of the region 3 prescribed in plane orientation, so that a current is fed only to a three-dimensional quantum well structure 18.

Abstract: PROBLEM TO BE SOLVED: To save a space and to reduce a cost by reducing the number of parts by constituting a power source button and a picture size switching button with the same operation button. SOLUTION: When a click part 20c is moved from an A3 position to a B3 position by moving a click SW member 20 operating integrally with the operation button (sharing the power source button with the picture size button) provided on the outside of a camera main body to the right by a prescribed distance, electric contacts 20a, 20b are moved from an A2 position to a B2 position, and power source is turned ON by an electric signal. A photographic picture at this time is a regular size picture as it is. When the click part 20c is moved from the B3 position to a C3 position by operating the operation button, the electric contacts 20a, 20b are moved from the B2 position to a C2 position.  Thus, a detection switch on a circuit substrate 21 detects that the size becomes a panoramic size picture, and a display in finder, etc., is revised, and the display is revised to the panoramic size picture.

Title: Head for ink jet printer
Inventor: SATO IKU
IPC: B41J2/05
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To short the foaming time in a pressure chamber and to be able to respond at a high speed by disposing a conducting heater for conducting to heat to generate foam in the chamber at the position deviated from an ink flowing line. SOLUTION: When ink is discharged by a head (IJP head) for an ink jet printer, the ink flows from an ink chamber 4 to an ink channel 3 to be filled in a pressure chamber 1, is given by kinetic energy from foam 6 formed by a conducting heater 5, and discharged from a nozzle 2.

Title: Method for disposing combustion exhaust gas
Inventor: SATOU IMATSU
IPC: F23J15/04
Filed: 1989-07-24
Abstract: PURPOSE:To treat various noxious gases to bring the gases into a completely harmless state by a method wherein combustion exhaust gas is reacted to saturated steam generated through spray of H2O, and produced acid liquid is neutralized by a basic neutralizer. CONSTITUTION:High temperature exhaust gas containing a noxious material generated from a combustion chamber 2 flows to a reaction chamber 10. When a pump 39 is run and H2O is sprayed in the direction of the length of the reaction chamber 10 from a nozzle 12 through an injection nozzle 40 by means of a pipe 38 running from a fresh water tank 37, particulates of H2O decreases the temperature of exhaust gas and is simultaneously brought into a saturated steam state. The particulates make contact with a noxious material in exhaust gas and reacts thereto and changes properties into saturated steam. Agitation is caused through intermolecule attraction of the particulates. The particulates adsorb and collect dust contained in the exhaust gas as contact and collision are repeated. With this state, the particulates flow in a primary neutralizing chamber 11 and produces acid waste liquid. Since a proper amount of a neutralizing agent in a neutralizing agent tank 41 is sprayed in the primary neutralizing chamber 11 from above through a working nozzle 13 with the aid of a pump 43, acid foam particles and waste liquid are immediately neutralized.
