Title: Linear motor
Inventor: IRIE SHINICHIRO
IPC: H02K33/18
Filed: 1990-10-31
Abstract: PURPOSE:To restrict a magnetic resistance as much as possible and obtain particularly big driving force by a method wherein the title device includes long permanent magnet pieces, arranged in a direction intersecting with the generating direction of flux, and a displacement member, provided with a coil wound so as to have the axial direction thereof in the lengthwise direction of the permanent magnets. CONSTITUTION:The length of an air gap between a permanent magnet piece 23 for a coil 25 and a second magnetic passage unit 29 is Ll while the element wire 22 of the coil 25 is provided with a laminated structure consisting of a copper wire 31 and an iron layer 32. According to such a structure, a magnetic resistance is reduced in the part of the iron layer 32, which is a ferromagnetic material, whereby the length of the air gap becomes particularly shorter substantially. Accordingly, a driving force, particularly bigger than so far, can be generated with respect to the same driving power from a DC power supply and efficiency is improved.

Title: Fuel injection controller for internal combustion engine
Inventor: NAGATA TETSUJI
IPC: F02D41/34
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To supress occurrence of a surge or a misfire in an internal combustion engine by properly-controlling required fuel injection quantity for a fuel injection valve. SOLUTION: Fuel injection valves 6 are set according to the maximum value of required fuel injection quantity, and when the required fuel injection quantity is small, the actual fuel injection quantity becomes unstable. Therefore, the minimum value of the required fuel injection quantity which can compensate for the required fuel injection quantity corresponding to an operating condition determined by an accelerator opening Ap from the accelerator opening sensor 30 of the internal combustion engine 1 and an engine rotational frequency NE from a crank angle sensor 29, is set according to fuel pressure PR from a fuel pressure sensor 27.  It is thus possible to improve the injection precision of the fuel injection valves 6 for the required fuel injection quantity, generate air-fuel mixture well ignitable in the vicinity of ignition plugs 5, and suppress occurrence of a surge or a misfire of the internal combustion engine 1.

Title: Data slicer circuit
Inventor: TAKAHASHI YOSHIAKI
IPC: H03F3/34
Filed: 1994-11-30
Abstract: PURPOSE: To compensate offset generated in an amplifier and a comparator and to provide output signals equal to the duty factor of input signals at all times by applying the DC output voltage of an integrator to the input terminal of a limiter amplifier. CONSTITUTION: It is assumed that the offset is generated in the limiter amplifier 5 and/or the comparator 6 and the voltage of +Va (-Va) is equivalently applied to the negative terminal of the amplifier 5. The threshold value of the comparator 6 becomes Vcc /2+Va(-Va), and when the input signals are converted to rectangular waves by the threshold values, the part of a Vcc level becomes narrower (wider) than the part of 0 level and the duty factor of rectangular wave signals is different from the duty factor of the input signals. The rectangular wave output signals whose duty factor is different from the input signals are integrated in the integrator 7 and the output voltage is lower (higher) than Vcc /2.  Thus, the DC voltage of the negative terminal of the amplifier 5 is decreased (increased), an offset voltage is compensated, the threshold value of the comparator 6 becomes Vcc /2 and the duty factor of the rectangular wave output signals becomes equal to the input signals.

Abstract: PURPOSE:To generate a required minimum thermo electromotive force in a short time after the start of heating by forming on outer shell element outside an inner element in a round or square column, and making its wall thickness smaller at a point nearer the point welded to the inner element. CONSTITUTION:An outer shell element 1 having a positive thermo electromotive force comprises multiple cylinders, and its wall is made thinner at a point nearer the end.

The positive thermo electromotive force is led to metallic part of a gas cock through a lead wire B6 to be fed to the solenoid valve 8 to complete an electrical circuit. The flame of gas effectively heats the joint where the cross section of the stepped round or square column is smallest and its wall thickness is thinnest, and so, the minimum thermo electromotive force required to hold the solenoid valve can be obtained in a short heating time.
