Abstract: PURPOSE:To permit faster growth of a higher-quality single crystal film at a lower temp. than heretofore by projecting electron rays so as to satisfy specific conditions to a substrate surface at the time of growing the single crystal film matched with the single crystal of the substrate surface by film deposition by vacuum deposition on the surface of the substrate, the surface of which is the single crystal. CONSTITUTION:The material of the same kind as the single crystal on the surface of the substrate having the single crystal layer on the surface or the material different therefrom is deposited by vacuum deposition on the surface of the above-mentioned substrate to grow the single crystal film of the above-mentioned material on the above-mentioned surface. The electron rays are projected onto said surface in a manner as to satisfy Bragg's reflection conditions with respect to one or plural crystal orientation of the single crystal layer of the above-mentioned substrate surface. The above- mentioned material is deposited on the substrate surface in the environment where the electron ray standing waves having the periodicity of the crystal lattice of the above-mentioned single crystal layer are made to exist on the substrate surface. The film of the single crystal of the above-mentioned material matching with the single crystal layer of the substrate surface is thus grown.

Title: Exhaust emission control method for internal combustion engine or the like
Inventor: TAKANASHI MASAKAZU
IPC: B01D53/56
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To neutralize harmful components to be non-noxious by making exhaust gas pass through a water solution containing bone meal and calcium carbonate in water. SOLUTION: A take, containing water and calcium carbonate, is installed at the outlet of exhaust gas. When exhaust gas and carbon monoxide are first made to pass through the water, water and carbon monoxide are bonded to convert into carbon dioxide and hydrogen. Secondly, hydrogen is bonded to nitrogen monoxide to convert into nitrogen and water. Subsequently, nitrogen dioxide changes into nitrogen and oxygen. Water is bonded to the nitrogen dioxide to convert into nitrate plus nitrous acid. Thus toxic components can be changed into a non-noxious component.

IPC: F23N5/24
Filed: 1993-06-01
Abstract: PURPOSE:To cope with a malfunction in an intermediate temperature range or one caused by, for example, attachment of soot by a method wherein, when during supply of power to the heater the amount of a change in temperature per unit time deviates from a preliminarily set range prescribed a lower limit and an upper limit, the supply of power to the heater is cut off. CONSTITUTION:A microcomputer 3 has a temperature gradient detector 4 and a heater controller 5 which jointly function as a temperature controller for a vaporizer. The temperature gradient calculator 4 constitutes a comparison circuit which, on condition that power supply to the heater 6 is on, calculated the amount of a change in temperature per unit time and, when this temperature gradient deviates from a preliminarily set range prescribing a lower limit and an upper limit, outputs a signal. The heater controller 5 constitutes a circuit which, provided that the temperature gradient detector 4 has outputted signals successively at certain intervals of time, outputs a signal to make a relay 8 transmit a command to cut off the supply of power to the heater 6. This method enables detecting a malfunction in an intermediate temperature range and even one caused by attachment of soot to a thermistor.

Title: Vacuum cooled electricity storage device installed in unipolar induction circuit
Inventor: YAMADA SADAYUKI
IPC: H02J15/00
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To adjust the electric capacity of an electricity storage box and obtain a large current flow by installing the electricity storage box made from a copper plate in a circuit connecting the periphery of a copper disc and the central shaft in unipolar induction and keeping the inside of the storage box vacuum. SOLUTION: When a copper disc 1 is rotated at high speed in unipolar induction, ether, that is, electrons as a fluid, stored between copper atoms in the copper disc 1 is sent out to the periphery of the copper disc 1 by centrifugal force. When an electricity storage box 4 is cooled at low temperature, it is known from the formula that if the pressure and volume of the box 4 are constant, the electron density increases with the reduction in temperature. The formula indicates that it is necessary to increase the pressure and volume besides lowering the temperature in order to charge the box 4. To increase the pressure, the copper disc 1 is rotated at high speed in unipolar indution to increase the pressure of the electrons in the periphery.  If the box 4 is cooled at low temperature, it is known from the formula that the electron density can be increased as much as desired, and therefore a large current flow can be obtained.

Title: Hydraulic buffer
Inventor: YABE KIYOSHI
IPC: F16F9/32
Filed: 1986-06-09
Abstract: PURPOSE:To obtain stable braking even when the component of lateral load is included in an external force by providing the remotest piston from the bearing part of the piston rod of a hydraulic buffer slidably on the inner peripheral face of a cylinder, and forming the passage of oil. CONSTITUTION:A piston 11a is slidable on the inner wall face of a cylinder 2, and plural smell holes 12 for allowing oil 1 to pass through are formed on it. When a piston rod 3 is pushed into the cylinder 2 by an external force F, the pressure of the oil 1 is increased by the piston 11a, generating a braking force against the piston rod 3. When the piston rod 3 is further pushed in, braking forces which are determined by the clearances between pistons 4b, 4c and the cylinder are applied to the piston rod 3 in order. In this case, even when the component of lateral load is included in the external force F, since the piston 11a functions as a bearing part, the load applied to a bearing part 10 is small.
