Title: Photosensor, information recorder and information recording/reproducing method
Inventor: SHIMIZU OSAMU
IPC: G01J1/02
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To attain recording of a high quality image free from changes in image density, uneven sensitivity and noise on an information recording medium by providing an electrode modification thin film layer between an electrode of a photosensor and a photoconductive layer. SOLUTION: An electrode modification thin film layer 16 is provided between an electrode 13 of a photosensor and a photoconductive layer (electric load generation layer 14', electric load transportation layer 14"). The thin film layer 16 needs transparency when the electrode 13 is transparent. But when the electrode 13 is not transparent, the thin film layer can be either transparent or opaque. The material providing a specific resistance of below 10<6> Ω.cm stably, for example, gold, platinum, copper oxide or indium oxide is used and applied on the electrode 13 at a thickness of about 3-100nm or preferably about 10-50nm by vapor deposition or sputtering.  The arrangement of the electrode modification thin film layer 16 can eliminate uneven contact between the electrode 13 and the electric load generation layer 14' to uniformize the injection of an electric carrier into the electric load generation layer 14 through the thin film layer 16 from the electrode 13 thereby reducing the unevenness and noises in the image.

Title: Switching element for field programmable lsi
Inventor: HAIDA OSAMU
IPC: H01L21/82
Filed: 1991-10-30
Abstract: PURPOSE:To simplify a manufacturing process, reduce necessary area, and manufacture a switching element for a field programmable LSI with a low cost equipment, by forming a part whose resistance is higher than A alloy, in a part of A alloy wiring which is above a diffusion layer and in contact with an oxide film on said layer. CONSTITUTION:Al alloy wiring 1 whose resistance is low is used as wiring material. In the Al alloy wiring between a terminal B and a terminal C, a high resistance part 3 whose resistance is sufficiently higher than that of the Al alloy wiring material is formed above a diffusion layer 5. When a voltage is applied across the terminals B and C, a high voltage is applied to the high resistance part 3, which remarkably generates heat. As a result, the Al alloy at a high temperature under the high resistance part 3 reduces an oxide film 4 under said alloy, and metal Si is formed. The metal Si is diffused in the Al alloy, and a terminal A and the terminal B are shorted via the diffusion layer 5. Thereby a switching element can be formed by using the area of three contact holes.

Title: Laser equipment
Inventor: KANEKO EIJI
IPC: H01S3/038
Filed: 1987-12-10
Abstract: PURPOSE:To obtain an output laser beam with an excellent efficiency and a high output power by a method wherein a radio frequency source is employed as an electric source and electrodes which are composed of conductor metal cylinders with partial apertures are employed as electrodes and the electrodes are arranged in parallel to each other so as to make the respective apertures face each other. CONSTITUTION:As a symmetrical arrangement wherein the apertures 22 of electrodes 13 are made to face each other is employed, the time-variation of the polarity of a glow discharge 14 can be sufficiently followed so that the utilization efficiency of the discharge can be significantly improved. In a radio frequency glow discharge, a part in which the luminance is relatively high exists at the position several millimeters to ten and several millimeters apart from the electrode and ionization is active in that part. In this case, if the electrode is hollow-type, by forming the electrode so as to have the thickness from several millimeters to ten and several millimeters contained in the hollow-type electrode, the ionization can be intensified. Therefore, generally speaking, the electrode diameter about the double of the thickness, i.e. from several millimeters to thirty millimeters is recommended. Thus, by applying the radio frequency electric field to the electrodes 13, a large power discharge can be performed.

Title: Semiconductor wafer heat-treating furnace
Inventor: TSUCHIYA YOSHIAKI
IPC: H01L21/22
Filed: 1988-12-08
Abstract: PURPOSE:To prevent the generation of the failure and the deterioration of the process tube for heat treatment use of a heat-treating furnace, which are caused by a thermal stress and the like due to a temperature difference, by a method wherein the cooling of the tube is performed directly with inert gas for cooling use controlled by a temperature control mechanism utilizing the exhaust heat of the furnace. CONSTITUTION:Inert gas passes through a heat exchanger 2 after its flow rate is controlled by a flow rate regulator 1, but a displacement, which is fed to the exchanger 2, is controlled by an evacuation flow rate regulator 6 at a gas temperature which is controlled by a temperature monitor 7. The preheated inert gas is fed between a process tube 3 for heat treatment use and a soaking tube 4 and is exhaused after a cooling is performed. The displacement, which is fed to the exchanger 2, is fed by a front scavenger 5 at the time immediately after a cooling system is actuated and the inert gas used mainly for cooling is utilized at the time of normal operation, but this is for the reason that the amount of heat, which is fed to the exchanger 2, is small at the time immediately after a cooling is started. Thereby, the tube 3 can be cooled while the inert gas is controlled so as to generate no failure and no deterioration in the tube 3 and the tube 4.
