Title: Ignition device for internal combustion engine
Inventor: MASUMOTO YOSHIHIDE
IPC: F02P3/08
Filed: 1986-06-12
Abstract: PURPOSE:To prevent drop of source voltage to an ignition control circuit when a constant voltage circuit is actuated, by connecting the output end of constant voltage circuit to the power supply circuit. CONSTITUTION:Cathode of a thyristor 1 constituting a constant voltage circuit, and one end of a resistance 3 to generate a gate trigger voltage for said cathode are connected to the anode of another thyristor 6 constituting a power supply circuit. When the charge voltage of an ignition capacitor 14 has attained a certain level, a zener diode 2 is actuated to turn on the thyristor 1. Through the thyristor 1, therefore, the output of the generator coil 1 is impressed on the power supply circuit without passing through a resistance 5. This eliminates drop of the voltage of power supply circuit.

Filed: 1989-06-02
Abstract: PURPOSE:To form a miniature circuit by reducing an oxide layer film with solution containing surfactant to form a second metal layer on the reduced surface, forming plating resist at necessary position of the second metal layer, and pattern-plating a board. CONSTITUTION:The surface of a copper layer provided on an insulating board is dipped with aqueous ammonium persulfate solution, etc., to be roughened, an oxide film layer is formed on the surface of the copper layer, a miniature uneven part is further formed thereon with aqueous alkaline chlorous acid solution, and the oxide film layer of the surface is reduced with aqueous solution such as dimethylamineboran containing nonionic surfactant. Then, a second metal layer having a base potential is formed on the reduced surface, a plating resist is formed on a portion except the circuit formed part on the second metal layer, and a desired circuit forming part can be pattern-plated by chemical copper plating. Accordingly, since a base metal surface for forming the plating resist can be made uniform, the plating resist is not peeled at the time of plating. Thus, a miniature circuit can be formed.

Title: Heating apparatus
Inventor: NISHIMURA SUEKICHI
IPC: F24C7/04
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To avoid re-energizing of a heat-generating body in an upset state even if an external force is applied to a shaft by providing a locking member having a locking portion which is locked to a peripheral portion of an opening when the engaging portion gets to engage with a corresponding engaging portion. SOLUTION: When an electric stove is turned over, an end portion 13c of a second shaft 13b gets into noncontact with a floor face 14. A shaft 13 is slanted at a specified angle (90 degrees in Drawing) with respect to a vertical direction. Therefore, a ring 19 slides downward along a slanted face 12 of a guiding portion 10 by self-weight and gets engaged with a groove 13e. Because an outer diameter of a locking portion 19b of the ring 19 is greater than a magnitude of an opening 9 formed in a face 6b of a bracket 6, the ring 19 is locked by the face 6b of the bracket 6. The shaft 13 is secured by the ring 19 and even if an external force is applied to the shaft 13 while the electric stove is being turned over, the shaft 13 is prevented from moving to an inner side of a housing so that re-energizing of a heat generating body is avoided.

Title: Thermal energy storage material
Inventor: YOKOYA FUMIKO
IPC: C09K5/06
Filed: 1983-07-29
Abstract: PURPOSE:To provide a thermal energy storage material which causes no phase separation even under repeated fusion/freezing cycles, prepd. by adding polyvinyl alcohol, formaldehyde and polyethylene glycol to a system consisting of sodium acetate and water. CONSTITUTION:Polyvinyl alcohol, formaldehyde and polyethylene glycol are added as thickener to a system consisting of sodium acetate and water and having a sodium acetate content of 53-69wt%. The three compds. are added in 0.5-20, 0.1-5 and 0.01-5pts.wt. respectively per 100pts.wt. above-mentioned system. Among thickeners, polyvinyl alcohol is crosslinked by the action of formaldehyde and increases the viscosity of fused thermal energy storage material, thus preventing sedimentation of sodium acetate. The polyethylene glycol presumably acts at the interface of fused thermal energy storage material and polyvinyl alcohol and prevents separation of the two.

Abstract: PURPOSE: To effectively perform biological filtration, when sewage, night soil or the like is purified in an active sludge process, by cleaning the packed layer of active sludge-adhering carriers in a biological filter with bubbling gas and purified water after biologically treated.  
     CONSTITUTION: Raw water such as sewage or night soil is biologically treated. The treated water, while its dissolved oxygen rate is raised by air from the first gas-flow line 13 in a biological filter 7, is carried through a feed line 11, a packed layer 14 and a discharge ine 15, to catch contained turbid matters with the packed layer 14. Thus, the raw water is continuously biologially filtered. When the packed layer 14 is washed,bubbling is done by injection of air from the second gas-flow line 17, a switch valve 5 is opened to feed treated water, an excess part of active sludge and turbid matters adherent onto carriers in the packed layer 14 are removed from the carriers, and then the treated water is returned through a return line 16 into a conditioning vessel. After washing is completed, a gas-flow line 13 and a circulating line 20 are opened,and the residual treated water is circulated into the packed layer 14 after washed and subjected to biological filtration. Thereafter, the operation is turned into an ordinary continous biological filtration process.
