Title: Method of forming solar energy sellective absorption film
Inventor: YANAGIDA MASARU
IPC: C25D11/22
Filed: 1981-09-01
Abstract: PURPOSE:To increase the diameter of a bore of an oxide film and increase alpha-value and epsilon-value by processing aluminum or its alloy in specific first, second, third and fourth steps. CONSTITUTION:In the first step in which a substrate such as an aluminum is subjected to anodic oxidation processing to form a porous anodic oxide film, a sulfuric acid bath, for example, is used. In the second step in which the porous anodic oxide film is subjected to immersion processing in an acidic solution, a phosphoric acid bath, for example, is used. In the third step in which the film is subjected to electrolysis and coloring in a bath including a metal salt, an ordinary process may  be used. In the fourth step in which hole sealing processing is performed, a steam hole sealing process or the like is used. By these steps, the alpha-value and the epsilon-value can be improved and dissolution of the film is made uniform. It is, therefore, possible to remove the irregularity in the selective absorption characteristic.

Title: Gas ignitor
Inventor: TAKADA MANABU
IPC: F23N1/08
Filed: 1978-11-08
Abstract: PURPOSE: To simplify the structure of, and to ensure the operation of, a slow ignitor which alleviates generation of combustion sound and soot upon ignition of a gas water boiler.  
     CONSTITUTION: As water flows in from a water inlet 13, a diaphragm 5 receives the pressure, displaces a diaphragm 6 and a receiver plate 26, and operates a rod receiver 33 through a rod 25. The gas having passed through a gas cock 37 is limited to a predetermined slow-ignition gas amount at a gap between the rod 25 and a metal 32 inserted in a gas valve 31, before being fed from a gas outlet 23 to a burner. Simultaneously with the displacement of the diaphragm 5, water flows from a water pressure chamber 8 also to a water passage 17 for slow ignition, so that the water pressure in a water pressure chamber 9 becomes equal to that in the chamber 8. The diaphragm 6 for driving the gas valve is displaced on receiving the pressure, the displacement is received by the rod 25, and the gas valve 31 is opened through a rod pin 28 to allow the flow of a full-open amount of gas.

Title: Semiconductor switch
Inventor: OHIGATA ICHIROU
IPC: H01L29/74
Filed: 1978-11-13
Abstract: PURPOSE: To increase dv/dt rating by providing a collector separately in addition to the p emitter and p base of a pnpn switch and bypassing the current flowing through the emitter form the collector.  
     CONSTITUTION: A p type base 5, collector 7 and emitter 3 are made within the n type base layer 4 encircled by n +  buried layers 8, 9, isolation layer 10 on a substrate 2. When the collector encircles the emitter of a lateral pnp transistor Q, β is larger than the converse of this. Hence, β 3  of the bypassing Q 3  by the layers 3-4-7 becomes larger than the β 1  of Q 1  of the layers 3-4-5. As a result, the carriers injected from the p emitter are collected more to the p collector and those flowing to the p base where feedback is applied become less, thus turning ON of the SCR is prevented and its dv/dt rating is increased.

Filed: 1994-06-21
Abstract: PURPOSE:To prevent an etching rate from changing almost at all for a long time and hence control etching easily by etching the upper surface of a formed film with an inert gas for flattening. CONSTITUTION:The upper surface of a formed film is etched by an inert gas for flattening the surface. For example, when etching back an organic SOG film 5, first an entire surface is etched back for 30 seconds by an etching gas CF4/CHF3/Ar=50/50/500sccm (S-1). Under the conditions, the etching rate does not decrease within 30 seconds. Then, an entire surface is etched back for five seconds with only Ar gas (S-2). Polymer formed on the surface of the organic SOG film 5 in the etching process in (S-1) is eliminated during the five seconds. After this, the processes (S-1) and (S-2) are repeated until the organic SOG film 5 at the upper part of Al wiring 3 is eliminated.

Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a temporary water tank which is lightweight and can be easily set up and moved and in which slid sediments can be easily removed by a method wherein a flexible partitioning part is provided near the bottom of a waterproof sheet to form an incision in a sediment in the bottom part, and a hanging belt is provided at a location where a bending force is generated in the partitioning part. SOLUTION: The bag-shaped article for a temporary water tank comprises a bag body 2 comprising a flexible waterproof sheet, a hanging belt 3, and a partitioning part 4 for dividing the bottom part of the body 2. When the hanging belt 3 is lifted, a downward force works on sediment 5 in the body 2 due to its own weight. An upwardly opening incision is formed in the sediment 5 continuous with a thin part between the part 4 and the belt 3, and an upwardly directed force is exerted on the incision. Thus, the sediment 5 is bent into an inverted V-shape and divided, starting from the incision opposed to the part 4. At that time, the part 4 is pulled, when it is lifted, so as not to be slackened, whereby the sediment 5 is surely broken.
