Filed: 1991-05-09
Abstract: PURPOSE:To prevent the splashing of toner outside a device and to reduce power consumption by arranging a nozzle spouting an air flow to the upstream side compared with a regulating member in a direction where a developer is carried by a developer carrier and toward the developer carrier. CONSTITUTION:A casing 3 is provided with a nozzle 16 on the upstream side compared with a regulating member 14 in the developer carrying direction of a developing roller 6 and in a location near to the regulating member 14. The nozzle 16 is formed so as to slantingly spout the air in a little upstream direction and toward a developing roller 13, and the blow-off port of the nozzle 16 is formed as a large number of small holes arranged in nearly parallel with the axial direction of the developing roller 6 at intervals. The air flow is supplied to the nozzle 16 by a fan connected with the nozzle 16, and the developer in front of the regulating member 14, for instance, of a doctor blade, is spouted toward the upstream side. At this time, the toner which is not sufficiently rubbed on a carrier is spouted, and prevented from being carried into a developing region with respect to a photosensitive body 1.

Title: Ignition timing control for internal combustion engine
Inventor: OBA HIDEHIRO
IPC: F02P5/15
Filed: 1986-05-07
Abstract: PURPOSE:To reduce the frequency of generating of engine stall due to the clutch meeting error on start by increasing the quantity of the air which flows in a bypass passage under a prescribed operation condition and delaying the ignition timing angle. CONSTITUTION:When the opening degree of a throttle valve 18 which is detected by a throttle opening degree sensor 20 is below a prescribed opening degree, and a clutch pedal 48 detected by a clutch switch 50 is stepped in, the quantity of the air which flows in a bypass passage 24 is increased by operating an ISC (idle speed control) valve 26 by a control circuit 46, and the ignition timing is delayed by a prescribed angle. Therefore, the output shaft torque is increased by the ignition by an MBT (Minimum Spark Advance for Best Torque) which shifts to the delay angle side in correspondance with the increase of the intake air quantity per engine revolution, accompanied with the reduction of the engine revolution speed due to the clutch meet, etc. on start, and the frequency of generation of the engine stall on the start of a vehicle can be reduced markedly.

Title: Fuel injection nozzle
Inventor: YOSHIZU FUMITSUGU
IPC: F02M61/08
Filed: 1995-04-05
Abstract: PURPOSE: To make the direction of fuel injection variable, according to the amount of lifting of the valve body, and improve combustion efficiency, by enlarging the tilt angle of the nozzle to the axis of the valve body more than the tilt angle of the valve seat of the nozzle, and making the valve seat larger than the opening of the nozzle. CONSTITUTION: When the pressure of the fuel forcibly sent to a fuel reservoir 23 reaches valve-opening pressure, the valve body 30 is lifted, and at the outset of lifting of this valve body 30, the fuel injected from a nozzle 37 is injected into a combustion chamber through the small space between the inside periphery of a valve sliding hole 21 and the outside periphery of the valve body 30. At this time, defining that the tilt angles of the valve seats 22 and the nozzle 37 to the axis L are α1 and α2 , respectively, they are set such that α1 <α2 , the direction of the first injection becomes one along the valve seat 22.  When the valve body 30 is lifted further, the fuel injected from the injection nozzle 37 is injected from the valve sliding hole 21, but immediately after injection, it bumps against the valve seat 22, and the direction of injection of the fuel is changed down. And, when the valve body 30 is lifted by the amount of maximum lifting, the fuel is injected as it is forward in the direction of extension of the injection hole 37.

Abstract: PURPOSE:To obtain a self-adhesive tape which can maintain the adhesive strength when applied to a protective side molding of an automobile, by using a composition consisting of a polyurethane containing isocyanate groups and a polyol on both sides of a double-side self-adhesive tape. CONSTITUTION:A chain extender comprising, e.g., ethylene glycol is incorporated into a polyurethane containing NCO groups, prepared by reacting a polyol, such as polyoxypropylene glycol, with a polyisocyanate, such as 4,4'- diphenylmethane diisocyanate, to give a composition, which is applied to the side of a tape, thus giving a self-adhesive tape. A polyurethane obtained by mixing a polyol and triethanolamine in a molar ratio of 1:0.05-2 and reacting this mixture with a polyisocyanate at a molar ratio of OH to NCO of 1:1.5-7 may be used for this self-adhesive composition. This self-adhesive tape is free from a reduction in adhesive strength due to a wax remover used for car washing and a fuel such as gasoline.
