Title: Cylindrical battery
Inventor: SHINODA KENICHI
IPC: H01M50/119
Filed: 1984-07-06
Abstract: PURPOSE:To increase the manufacturing efficiency of a cylindrical battery by greatly reducing the incidence of buckling by providing the metal jacket with a split curled area the cut of which has R areas with proper shape. CONSTITUTION:The cut 5 of a metal jacket 1 has R areas. The ratio of the peripheral length of the R area to the height of the cut 5 (R/h) is adjusted to the within the range of 1.5-3.3. When this ratio is smaller than 1.5, buckling is caused during curling of the jacket 1. When the ratio is larger than 3.3, although buckling is not caused, the jacket 1 is not favorably attached around the generation element because the end surface of a split curled area 4 becomes too extended after the curling. By this providing the cut 5 of the split curled area 4 of the jacket 1 with the R areas and specifying the ratio of the peripheral length of the R area to the height of the cut 5 to be within the range of 1.5-3.3, the incidence of buckling is greately reduced thereby increasing the manufacturing efficiency of a cylindrical battery.

Abstract: PURPOSE:To simplify the structure of gear interlocking mechanism by engaging and arranging in the same level, gears driven by a driving gear integral with a crank shaft. CONSTITUTION:A driving gear 3 integral with a crank shaft 2 and an idle gear 5 driving an oil pump 4 directly rotate each other with engagement and the gear 5 drives an air inlet-exhaust cam shaft 6 through a cam gear 7, a fuel injection cam 8 through a cam gear 9 and also drives a balancer shaft 10 through a balancer gear 11 respectively. Consequently above mentioned mechanism rotates and interlocks each air inlet-exhaust valve, a fuel injection pump and a balancer weight. At the same time, the load generated from driving of the oil pump 4 affects on the gear 5 regularly. Although load change affects as much on the gear 7, 9, 11, and others as on the gear 3, ordinarily generated load and inertia decrease the noise and the variation of backlash.

This method receives a multi-level gradation picture element value denoting picture elements with a 1st resolution. The multi-level gradation picture element value is subjected to screen processing and the screen picture element value is equal to (GL-V1 )+(S1 -Th), where G1 is a maximum gray level of a picture element, V1 is a multi-level gradation picture element value with the 1st resolution, S1 is equal to a screen picture element value corresponding to the position of the picture element and Th is a threshold level.  Then the level number of the multi-level gradation picture element value subjected to screen processing is reduced and an error is generated as a solution to the reproduction process. The error generated thereby is spread to the multi-level gradation picture element of an adjacent picture element.

Title: Cooling of steel material
Inventor: OZAWA MASATOSHI
IPC: B21B45/02
Filed: 1983-08-02
Abstract: PURPOSE:To uniformly cool over the whole surface of steel materials, by dipping the steel material, under an inclined state, on cooling the steel material by completely dipping it into coolant. CONSTITUTION:The steel material 13 adhered with the deposit by, for example, hot top frame after ingot making, oxidation film inhibitor, etc. is fixedly put on the cooling stand 12 formed, in a network structure, installed in the water tank 11 and completely dipped into the coolant 14. Then the coolant or air is injected from the injection nozzle 15 provided just under the steel material 13 and the steel material 13 is rapidly cooled stirring the solution 14. Though water vapor is gnerated from the surface of steel material 13 simultaneously therewith, this water vapor floats upward as it is from the upper and side surfaces of steel material 13 but is difficult to float at the bottom surface. Then, the upper surface of stand 12 is inclined and the steel material 13 is made to be of inclined state in the solution 14. Therefore, the water vapor on the bottom surface of steel material 13 is flowed along the bottom surface of steel material 13 together with the flow of coolant or the like from the nozzle 15 and thereafter floats upward. Thus, the steel material is rapidly cooled uniformly over its whole surface.

IPC: F01M1/16
Filed: 1978-11-15
Abstract: PURPOSE: To prevent oil from being sealed and locked in the pump chamber and adjust the amount of discharge smoothly, by providing an oil hole which links the pump chamber in the distributor to the inlet and the outlet alternately.  
     CONSTITUTION: Pump chamber 30 is provided with plunger 38, which makes reciprocating motion in coordination with the rotation of distributor 29 so that it is moved backward when oil hole 31 is linked to inlet 25 and it is moved forward when oil hole 31 is linked to outlet 26.

Abstract: PURPOSE:To automatically correct the dispersion of the input and output characteristic of a detecting means by detecting reference pressure or wind quantity, which is added from an external part, with the detecting means and storing the output of the detecting means to a non-volatile temporary storing means as a reference output for control with an operating means. CONSTITUTION:At the time of manufacture, the reference pressure or reference wind quantity of a value, which is determined in advance, is added from the external part to a detecting means 176; Then, since storing operation is instructed from the external part through the operating means to a control means 162, the output of the detecting means 176 to the reference pressure or reference wind quantity is stored to a non-volatile temporary storing means 199 in this control means as the reference output for control. At the time of cleaning, for example, in correspondence to the pressure or wind quantity in an air course to be detected by the detecting means 176, the output of an electric blower 107 is controlled by the control means 162. However, in such a case, the dispersion of the input and output characteristic of the detecting means 176 is corrected by the internal part of the control means based on the stored reference output for control.

Abstract: PURPOSE:To enable a heat distribution characteristic to be readily adjusted and to prevent a discharge between slits by allowing a pair of circular conductors to work as a second feeding electrode, supplying high-frequency power to a plurality of coils from the circular conductors, and allowing semiconductor crystals to hold impurities uniformly. CONSTITUTION:When a high-frequency current is supplied between the power terminals 23a, 23b of a high-frequency induction heating coil 30, high-frequency currents flow among small coils 24a-24f and 25a-25f between circular conductors 21, 22.

In a hollow area 26, a magnetic field is created in a direction of flow from the top to the bottom of the paper surface by currents flowing through the ends of the coils 24a, 24b. Magnetic fields are created also in the coils 24b-24f, 25b-25f. Fluctuating magnetic fields that are in axial symmetry as a whole with respect to the axis of the hollow area 26 are created, and eddy currents flow through raw- material polycrystals 1 disposed in the hollow area 26 and through a molten band 4 to heat the raw-material polycrystals 1 and the molten band 4, yielding rod-shaped semiconductor crystals.
