Title: Air intake device of internal combustion engine
Inventor: OSUGA MINORU
IPC: F02B31/02
Filed: 1993-11-08
Abstract: PURPOSE:To concentrate air-fuel mixture in the vicinity of the ignition plug position in a cylinder so as to improve ignitability at the time of lean combustion by preventing ununiformity of air-fuel mixture distribution inside the cylinder, uniformalizing it, and selecting supply direction of atomized fuel. CONSTITUTION:Fuel injected fro a fuel injection device 21 and atomized by colliding with an intake valve 14 flows into a combustion chamber 19 from this side of the intake valve 14. On the other hand, the high speed air flow from a bypass passage 10 flows from the ignition plug 16 side of the intake valve 14 into the combustion chamber 19, and then tumble flow is formed inside the combustion chamber 19. Consequently, ignitability is good since the air-fuel mixture distribution inside the cylinder can be uniformalized or, can be stratified, and further stable combustion with lean air-fuel mixture can be gained since the combustion is expedited by swirl flow generated inside the cylinder. Fuel consumption is then decreased, and additionally, quantities of HC and NOx can be remarkably decreased.

Title: Magnetron driving method
Inventor: OGURO TOMOKATSU
IPC: H01J25/50
Filed: 1990-10-19
Abstract: PURPOSE:To prevent the deterioration of the electron emission capacity of a cathode by varying an anode current on a step-by-step basis when changing over the output of magnetrons CONSTITUTION:When the output of magnetrons is changed over from a full- power state to a small-output state, a relaxation time of t1 3 seconds. e.g. is given to accommodate an intended current value on a step-by-step basis. Longer t1 is prefered in terms of cathode deterioration because less thermal shock is given to a cathode, but too much longer t1 is inconvenient for output control. A range from one second to ten seconds is recommended, preferably two to three seconds specially in the case of making great account of cathode deterioration prevention.

Filed: 1991-10-25
Abstract: PURPOSE:To provide a stable high-frequency oscillating output and stabilize therapeutic effect regardless of the degree of wear of a storage battery by connecting a constant voltage circuit to the input power source side of a high- frequency oscillating circuit. CONSTITUTION:A constant voltage circuit is connected to the input power source side of a high-frequency oscillating circuit or a constant voltage circuit in an integrated circuit is used also as the constant voltage circuit. Namely, since an oscillating circuit which is the base of the adding and subtracting clock of a charge counter is driven by the constant voltage circuit T in the integrated circuit, its output Vreg is used also so that a Colpitts oscillating circuit X can be driven. Consequently, the high-frequency oscillating circuit is easily stabilized only by a wiring. The Colpitts oscillating circuit X occupying 90% of the consumed current is stabilized, whereby the consumed current I1 is stabilized and made constant, so that the subtracting counter can be easily and precisely set.

Title: Method for winding magnetic recording medium
Inventor: YASUDA JUN
IPC: B65H18/00
Filed: 1984-12-28
Abstract: PURPOSE:To prevent peeling off of magnetic coating due to mutual contact of magnetic paint by superposing a film made of synthetic resin and winding simultaneously when winding a base film coated with magnetic paint on both sides on a core. CONSTITUTION:A magnetic recording medium 4 for which calender process by an elastic roll 1 and a metallic roll 2 is completed is led by a guide roll 3 and wound on a core 5. During calender process and winding process by the core 5, a film 7 is supplied from a core 7 on which a film 6 made of synthetic resin is wound, and the core 5 is taken up simultaneously with the magnetic medium 4. By simultaneous winding, magnetic paint coated on the surface of the magnetic recording medium 4 does not come into direct contact with magnetic paint any more. Accordingly, the magnetic paint no more separates magnetic paint on the magnetic recording medium 4 by its adhesion. Consequently, the surface becomes the state worked by calendering process. Thus, yield is improved remarkably.
