Title: Deformed swirl combustion chamber
Inventor: WADA YUKIYO
IPC: F02B23/04
Filed: 1986-06-14
Abstract: PURPOSE:To enable a higher thermal efficiency, better startability, higher smoke generating limit, less NOx emission quantity, and less excess air ratio to be obtained by providing a plunger which rises or falls when the pressure inside a combustion chamber reaches a given value. CONSTITUTION:A plunger 4 is raised by the pressure rise caused by the compression of air inside a combustion chamber 8 due to the rise of a piston 10. Before or at the same time when air flows thereby quickly toward a plunger barrel 7, fuel is injected from a fuel injection nozzle 9. Accordingly, by causing nearly simultaneously swirls and combustion eddy currents by the deformation of combustion chamber accompanied by the rise of the plunger 4, the mixture formation ranging from a low-speed region to a high-speed region can be improved. Further, since the plunger 4 is controlled by a spring 6 so that it cannot be raised until the pressure inside the combustion chamber 8 reaches a given value, even at the time of starting, a compression pressure in the neighborhood of that during the normal operation can be attained.

Abstract: PURPOSE:To prevent the current concentration of a static induction type thyristor by forming a reverse conductive type high impurity layer on the emitter of the thyristor and constructing to increase the carrier injection efficency from the emitter to the base as it is separated farther from a channel unit. CONSTITUTION:A P<+> type emitter layer 6-1 having the widest width is formed at the periphery farthest from a channel unit, and an emitter shortcircuit unit N<+> type laer 12-1 is formed at the near side to the channel unit adjacent to the layer 6-1.

Filed: 1990-05-30
Abstract: PURPOSE:To reduce the blackening of the electrode sealing end part of a bulb to prolong the life of a lamp by tubularly forming a pair of cold cathodes with a conductive plate, and inwardly folding its end surface. CONSTITUTION:In each cold cathode 13, both the left and right end parts, in the longitudinal direction of a rectangular metal-made thin plate having conductivity, are made slits 13a and 13b, and are inwardly folded individually at a given angle. Then these left and right folded end parts 13c and 13d are mutually abutted, and the slits 13a and 13b are cylindrically folded so as to be inwardly took in. This eliminates a projection to the outward of the outer peripheral surface to restrain the occurrence of sputtering due to the concentration of negative glow at one end part of the cold cathode 13. Consequently blackening, due to the adherence of an electrode material to the inner peripheral surface of a bulb 12, is reduced to prolong the life of a fluorescent lamp 11.

Abstract: PURPOSE:To simplify structure, and to facilitate production by composing one part of winding groups connected in parallel of main winding and tap ped winding and constituting remainder groups by main winding and winding, which is connected in parallel with tapped winding but has no tap. CONSTITUTION:In the transformer such as a single-phase two leg transformer, the main winding 2a and the tapped winding 2a' are wound on a core leg 1a, the main winding 2b and the winding 2b'' with no tap are wound on a core leg 1b, and these are connected in parallel.
