Title: Method and apparatus for thermally decomposing dust containing polyvinyl chloride
Inventor: SUZUKI TAKEKAZU
IPC: C10J3/00
Filed: 1993-11-29
Abstract: PURPOSE:To reduce acidic substances in a dry distillation gas and enable the use of a solid residue by dry distilling a dust contg. polyvinyl chloride in the presence of an alkali or alkaline earth metal salt, bringing the resulting solid residue into contact with water, and recovering the resulting product. CONSTITUTION:An alkali or alkaline earth metal salt (e.g. Na2CO3 or CaO) is added to a plastic dust which is produced by shredding automobile wastes, etc., and contains polyvinyl chloride in a large proportion and nonferrous metals. The dust is then sent from a hopper 1 through a passage 4 to a retort 13 of a dry distillation oven and baked there at 350-500 deg.C to separate into a gas, an oil, water, and a solid residue. The resulting gas is sent from an exit 9 installed on the way of the passage 4 through a buffer tank 10 to the dry distillation oven to be utilized there as a fuel. Chlorine is fixed in the residue and converted into chlorides, which, by putting the residue into a water tank 20, is separated from a solid component mainly comprising carbon. Thus, the chlorine content in the dry distillation gas is reduced, dispensing with the washing step, and the solid component can be used as a fuel, etc.

Title: Pachinko game machine
Inventor: UCHIGASHIMA TOSHIHIRO
IPC: A63F7/02
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To simplify configuration for controlling launching and releasing devices and also to simplify work associated with the change of a board in a pachinko game machine. SOLUTION: As an inner frame controlling device 72 controls a launching motor 102 and releasing motor 56, configuration for controlling launching and releasing devices becomes simple. In addition, the inner frame controlling 72 controls a stop lamp L4, the flashes of a full lamp L5, full panel 29, and the display of an LCD displaying device 82 on the basis of signals from a full switch 68, supply switch 49, and relay channel switch 55. As the stop lamp L4, flashes of the full lamp L5, full panel 29, and LCD display 82 are located outside a game board, it is not necessary to capture signals from the relay channel switch 55 into the side of the game board and wiring for this is not necessary, either. Therefore, work associated with the exchange of a face becomes simple.

Title: Anti-cathode for x-ray generation
Inventor: OSAWA MICHIO
IPC: G01N23/20
Filed: 1986-12-16
Abstract: PURPOSE:To enable simultaneous using of a plurality of goniometers which use different characteristic X-rays by disposing a plurality of different elements, which generate required characteristic X-rays, on a surface of an anti-cathode irradiated with electron beams. CONSTITUTION:A metallic Cr 1 and a metallic Mo 2 are disposed in series on a surface of an anti-cathode irradiated with electron beams 5 and in the rotational direction of the anti-cathode. When this anti-cathode 8 is rotated around a rotating axis 4 and irradiated with the electron beams 5 coming from a filament 3, the beams 5 impinge on Cr atoms and Mo atoms, and so Cr-Kalpha rays and Mo-Kalpha rays are generated as characteristic X-rays from the respective atoms. When the anti-cathode in such composition is used to form a non-enclosed type X-ray tube bulb of anit-cathode rotation, a high cooling effect of the anti- cathode enables strong radiation of the beams 5, so that two species of strong characteristic X-rays can be generated from a single anti-cathode.
