Abstract: PURPOSE:To simply obtain a permanent magnet in which S-poles and N-poles are continued alternately via non-magnetic-flux regions by a method wherein one of the N-poles and the S-poles is formed in regions which are faced with first protruding parts of a piece to be magnetized, the other of the N-poles and the S-poles is formed in regions which are faced with second protruding parts and the non-magnetic-flux regions are formed in regions which are faced with third protruding parts. CONSTITUTION:A magnetization yoke 20 is provided with respective yokes (protruding parts) 21a, 21b, 21c, 21d for short-circuit use between protruding parts 20a, 20b, 20c, 30d; coils 50a, 50b, 50c, 50d for short-circuit use are wound on the individual protruding parts 21a to 21d. When a switch 28 is first closed instantaneously and an electric current is made to flow to a magnetization coil 22, a magnetic flux F is generated in the magnetization yokes 20a, 20b and one part F1 of the magnetic flux is passed through the yokes for short-circuit use. An electric current flows in the coil 50b for short-circuit use at a phase delay of about 90 deg. with reference to the electric current inside the coil 22 so as to generate a magnetic flux F2 which offsets the magnetic flux F1. Consequently, the magnetic fluxes F1 and F2 are offset mutually inside the yoke 21b for short-circuit use. As a result, the magnetic flux passing inside the yoke for short-circuit use is reduced.

Title: Deviation preventing mechanism for endless film
Inventor: KAMIYA NANISAKU
IPC: G03G15/20
Filed: 1993-11-16
Abstract: PURPOSE:To avoid complication of a device so as to simplify a constitution by arranging a thin leaf spring, spirally wound in a simple substance condition, in a roller member rotatably provided in a tensioner shaft end part of an endless film. CONSTITUTION:When turning force is applied to a roller 6 from an endless film 1, the roller 6 tends to rotate in a direction of arrow mark (A), to unwind a thin leaf spring member 9 by increasing a contact area between the film 1 and the roller 6, or when a position of a driven roller 3 is restricted by a stopper member 11, energy is increased larger than the energy accumulated in the member 9 in this position. Then, the roller 6 is rotated in a direction of the arrow mark (A) and made movable in a direction of arrow mark (C) so as to be unwound from the member 9. When the film 1 is started to be laid in a direction of decreasing the contact area between the film 1 and the roller 6, the roller 6, while rotated in a direction of arrow mark (B), is wound to the member 9 and moved in a direction of arrow mark (D). Thus by balancing energy, an end part position of the driven roller 3 is determined, and the film 1 is stably turned in a fixed range.

Title: Electronic control unit injector
Inventor: NAGAE YOSHINORI
IPC: F02M61/20
Filed: 1993-11-16
Abstract: PURPOSE:To stabilize high speed low load driving by arranging a stopper plate having a throttle port on a lower side of a plunger chamber, and also arranging a valve spring and a valve opening pressure adjusting shim between a piston which is abutted against the stopper plate from the opposite side of the plunger chamber and a fuel valve. CONSTITUTION:Fuel which is supplied to a fuel supplying/discharging passage 5 of an injector main body 1 is pressed to an oil reservoir 12 from a fuel passage 11 by descending of a plunger 2. When an electromagnetic coil 8 is excited and an armature 7 is pulled up, a poppet valve 6 is lifted and the fuel supplying/ discharging passage 5 is closed. Thus, pressure is increased in the fuel valve oil reservoir 12 or a plunger chamber 16. As a result, a fuel valve 14 is lifted against a valve spring 13 and a fuel valve injection port 15 is opened. At a lower side of a stopper plate 21 having a throttle port 22, a piston 17 is lowered until it is abutted against a stopper 20. Pressure increase of the oil reservoir 12 is suppressed, while flexure of the valve spring 13 is adjusted by a valve opening pressure adjusting shim 18.
