Title: Distribution type fuel injection pump
Inventor: NISHIWAKI TADASHI
IPC: F02M41/14
Filed: 1992-11-25
Abstract: PURPOSE:To provide a distribution type fuel injection pump where the wear and seizure of a distribution rotor can be prevented, and the spill performance is excellent. CONSTITUTION:As a diesel engine is started, the fuel is fed by means of a wane feed pump 19 from a fuel tank 17 to a feed gallery 51 through a non- return valve 23. This fuel is introduced into a plunger chamber 41 through the suction stroke of a plunger 39 in a distribution rotor 37, and successively, into a distribution passage 52 provided in a distribution head 47 through a distribution passage 52 of the distribution rotor 37 through the distribution stroke of the plunger 39, and injected from the nozzle. On the other hand, when an infection quantity control valve 59 is opened, and communication is made with a spill passage 57, the high pressure fuel in the plunger chamber 41 is overflowed and introduced into a cam chamber 27, and the pressure is reduced to provide the low pressure fuel. This low pressure fuel is then re-introduced into the vane feed pump 19 through a fuel recycling passage 63.

Title: Magnetism detecting device
Inventor: HARUMI SHIGEHIRO
IPC: G01D5/245
Filed: 1994-12-19
Abstract: PURPOSE: To provide a magnetism detecting device wherein offset error caused by deviation between a bias magnet and a magnetic reluctance element in the direction of a principal plane of a sensor part is reduced. CONSTITUTION: A pair of bias magnets 11 and 12 are, with a magnetism detecting position P in between, while at the opposite positions in x-direction parallel with a principal plane of a sensor part, extended in y-direction which is parallel with the principal plane of the sensor part and perpendicular to the x-direction. Further, pole faces on the side facing the sensor part of both the bias magnets 11 and 12 have polarities reverse to each other. Thus magnetic field almost toward the x-direction is formed at the magnetism detecting position P, so that magnetic field intensity at each point on a line extending in the x-direction, including the magnetism detecting position P, are almost equal to each other.  So that, even when a magnetic reluctance element of the sensor part is relatively displaced in the x-direction to the bias magnets, magnetic field component acting upon the magneto-resistance element is hardly changed, and the change in reluctance value is also small.

IPC: B41J2/235
Filed: 1990-11-20
Abstract: PURPOSE:To improve effect for radiating heat generated from a piezoelectric element by covering a plurality of printing units with a cooling cover, forming protrusions from said cover to allow them to extend between the printing units and filling thermally conductive synthetic resins between the protrusions and the printing units. CONSTITUTION:Synthetic resins having high thermal conductivity such as silicone rubber 4 are filled into gaps around each printing unit 9 including gaps between the printing unit 9 and protrusions 7a of a cooling cover 7 and gaps between piezoelectric elements 13 and a frame 15.
