Title: Permanent magnet field motor
Inventor: KANETOSHI KAZUHIKO
IPC: H02K23/04
Filed: 1985-06-24
Abstract: PURPOSE:To improve the yield of a permanent magnet piece and to enhance the dimensional accuracy of a field by forming a flat portion at the prescribed position of the inner surface of a yoke, securing the flat permanent magnet thereto, and further mounting a magnetic member having an arcuate surface thereon. CONSTITUTION:A flat portion 1a is formed at the prescribed position on the inner surface of a yoke 1. A flat permanent magnet 2 is mounted on the portion 1a.

Abstract: PURPOSE: To evenly diffuse a fuel in a combustion chamber at the same time with an opening of an intake valve, reduce the quantity of wet to the intake valve etc. reduce the HC discharge quantity, and improve the accelerated responsiveness by symmetrically arranging plural chevron shaped nozzles to the injection part of a fuel injection valve. CONSTITUTION: Fuel injected from a pair of nozzle 54a, 54b which are formed in the injection part 6 of a fuel injection valve 5 to be symmetrical with respect to a point, and of diametrically chevron shaped cross section, is injected as a spray in the direction determined by the angle of an inclined passage formed between a tapered part provided at the tip of a needle valve 17 and a tapered part provided at the tip of an opening 51 of a body 20. The fuel spray strikes the back face sides on remote sides viewed from the stems 2 in the back face of the intake valve 1, that is, the surface of umbrella parts 1a. Thus, when the intake valve 1 is opened, the fuel spray is atomized by shearing action of the air stream, and since the air flows into a combustion chamber without delay, the fuel is diffused evenly.

Title: Sheets sorter device
Inventor: YOMO MAKOTO
IPC: B65H39/11
Filed: 1982-08-04
Abstract: PURPOSE:To group transcript sheets and accumulate them by formats in a sorter device for transcript sheets sent from a copying machine by allowing a cam to directly interfere between the upper and lower trays and by pushing open the space between the trays by a low drive force. CONSTITUTION:When sheets are received by a tray 53, the boss 101 of a cam 10 shall directly interfere between the trays 52 and 53, and the end is put in contact with the right and left sides of the notch tip of the tray 52 to push open it in the direction as up and down. Thus the space between trays 52 and 53 is held opened. Here this energized condition in the direction as up and down is reinforced by a coil spring 123, so that no compressive force is being applied to the boss 101. When the tray 53 is fed with sheets, a stepping motor will start to rotate the cam 10 clockwise, and the whole group of trays also begin sinking. When the cam 10 has turned approx. 30 deg., the boss 101 will retract from position between trays 52 and 53, and the tray 52 approaches the other 53 because of restorative force by the spring.
