Title: Manufacture of chip type film capacitor
Inventor: KUBO YASUHIRO
IPC: H01G4/18
Filed: 1988-03-03
Abstract: PURPOSE:To make the title film capacitor smaller than a chip type film capacitor through molding by adopting a sheet sheathing system and using a sheet sheathing, sheathing thickness of which extends over 0.3mm or less. CONSTITUTION:Capacitor elements 5 to which frame plates 6 are welded are arranged continuously with regular intervals 8 onto a sheet 7a for sheathing composed of a beltlike base-material contained double-side thermosetting resin prepreg sheet having thickness of 0.1-0.3mm the same width as the width of the metal sprayed sides of the capacitor elements 5. A fixed quantity of a liquefied epoxy resin 9 having a viscosity ratio of 2-7 is fed into the intervals 8, and a beltlike sheet 7b for sheathing having the same material as the sheet 7a for sheathing is placed onto the epoxy resin 9. The frame plates 6 are bent to a U shape along the sheets 7a, 7b for sheathing, and cured in specified size through heating and pressuring, thus shaping a beltlike cured article 10 sheathed with the sheets. Accordingly, the title film capacitor can be miniaturized.

Inventor: MURATA MITSUHIRO
IPC: G01N27/12
Filed: 1981-04-02
Abstract: PURPOSE:To discriminate and detect drying, dewing, and frosting by connecting a resistor which varies from a low resistance value to a high resistance value according to a dewing and frosting state in parallel to a resistor which varies from a high to a low resistance value according to a dewing and frosting state. CONSTITUTION:The 1st resistor R(P) has low resistance values R(P)T1 and R(P)T5 in drying states T1 and T5, and a high resistance value R(P)T in dewing states T2 and T4, and a frosting state T3. The 2nd resistor R(N) has a high resistance value in drying states T1 and T5, and a frosting state T3, and low resistance values R(N)T2 and R(N)T4 in the dewing states T2 and T4. Those resistance bodies are connected together in parallel and their current values are detected; the current flows to a resistance body having a lower resistance value relatively in each state. Consequently, currents having different values flow in the drying state T1, dewing state T2, and frosting state T3, so that the respective states are detected.

IPC: F02M25/00
Filed: 1979-04-27
Abstract: PURPOSE: To suppress the generation of NO x , by adding an acetic acid of a prescribed molecular formula or an isomer of said acid or a mixture of the acid with water to the fuel of a gasoline engine.  
     CONSTITUTION: An acetic acid represented by a molecular formula C 2 H 4 O 2  or an isomer of the acid or an aqueous solution of the acid is introduced from an upper water tank 5 to a carburetor 7 through a float chamber 6 so that the acetic acid, the isomer or the aqueous solution is added to the fuel of a gasoline engine. A water injection hole for the added substance is so arranged that the hole acts for a recycled exhaust gas injection port 1 and an atomizer 3. Water containing the additive is thus sucked and atomized. The atomized water is injected together with the exhaust gas into a mixture of the fuel 8 with air 9.

Title: Winch follow-up controller for traveling robot
Inventor: YAMASHITA HIRONOBU
IPC: B25J5/00
Filed: 1990-03-05
Abstract: PURPOSE:To have a winch driver followed up at the specified tension at all times by adding a velocity compensation value, made up of converting a wire tension deviation, to the velocity that is converted from travel speed of a traveling robot to rotational speed of the winch driver, and setting it down to a speed signal. CONSTITUTION:When travel motion of a traveling robot 1 meanders and so on, making a wire 3 loose to some extent, and the tension detected value of a tension sensor 8 becomes smaller than the setting value of a tension setter 10, a subtracter 13 outputs a negative tension deviation, whereby the rotational speed compensation value of a winch 2 being converted by a second operational means 9 comes to a negative value. If so, this negative value is added to a rotational speed command to be found by a first operational means 5 equal to travel speed of the traveling robot 1 by an adder 12. This driving command is given to a winch driver 6 and a delivery speed of the winch 2 is decreased, and when the wire 3 is stretched and its tension goes up more than the tension setting value, the subtracter 13 outputs a positive tension deviation, and thereby the speed compensation value of the winch 2 to be found by the second operational means 9 comes to a positive value, thus the wire delivery speed is increased.

Title: Alternate writing system for optical disk
Inventor: HAYAKAWA AKIRA
IPC: G11B20/18
Filed: 1988-03-04
Abstract: PURPOSE:To improve the use efficiency of an optical disk by successively executing alternate writing from the last sector of the last track of the optical disk to its preceding sector when the alternate writing becomes necessary instead of previously assigning an alternate area. CONSTITUTION:A processor 12 of an optical disk controller 10 successively executes the increment of addresses in a direction from the first sector of the first track of the optical disk to the last sector of the last track of the optical disk and writes data to a RAM14, and the processor 12 successively executes the decrement of the addresses in anther direction from the last sector of the last track of the optical disk to the first sector of the first track of the optical disk and executes the alternate writing whenever failure occurs in the writing of the data. Thus, since the processor 12 writes the data to an optical disk unit 11 based on the instruction of an instructing means 16 until a user area and the alternate area adjoin each other, no unused area remains on the optical disk, and the use efficiency of the optical disk can be improved.
