Filed: 1987-09-19
Abstract: PURPOSE:To ensure the required attenuation at a carrier signal frequency with a large current capacity by combining a I-shaped core of a power inductor superimposed with a commercial power current to assemble the cores in a form of H. CONSTITUTION:A power inductor 11 is connected in series with each line of single phase 3 wire power lines, respectively. Four I-shaped cores are used for the inductor 11 and the I-shaped core is arranged at both ends of the coil 1 through a bobbin 8 and four cores are assembled by the H shape. Through the constitution of the cores as above, the coil of the inductor 11 is superim posed with a large current of the commercial frequency and even when the current amplitude of the cores constituting the inductor is changed, the inductor has less permeability. The inductor 11 and the capacitor 7 form a parallel resonance circuit and has a high impedance to a carrier frequency and the series resonance circuit comprising a variable inductor 12 and a capacitor 6 forms a low impedance circuit between a neutral line 14 and a live line 13 at a carrier signal.

Filed: 1987-09-19
Abstract: PURPOSE:To improve S/N by feeding back positively an output voltage of a photovoltaic infrared ray sensing element to a base potential of the photovoltaic infrared ray sensor via an impedance conversion means whose gain is <=1. CONSTITUTION:An optical current caused by an infrared ray received by the photovoltaic infrared ray sensing PV element 1 and an output voltage decided by the internal resistor of the element 1 are given to a gate electrode 21 corresponding to the gate of an FET 6 by an N<+> diffusion layer 11. Then the signal is fed back positively to the base 10 of the element 1 from the N<+> diffusion layer 17 while impedance conversion is applied by the FET 6. Thus, the gain of the source follower by the FET 6 is realized easily for nearly 0.9, then the output voltage is improved by nearly 10 times. Then the PV element output voltage is increased even under at a high temperature condition in a long wavelength light receiving PV element and the S/N of the signal injected to the signal processing circuit is improved.

Title: Fuel supply device
Inventor: NARUSE HIDEO
IPC: F02D41/22
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To accurately detect abnormality of a fuel flow amount by providing a position detection means detecting a position of a valve member which is displaced in accordance with the fuel flow rate, in a fuel cutoff valve provided in a fuel supply route to interrupt it when fuel of specified rate or more flows. SOLUTION: At the time of normal fuel flow, when it is injected from a fuel injection valve, the fuel flows in a fuel passage 21a, and by generating a differential pressure between the upstream/downstream of an orifice 31a, a piston 31 is moved downward. After completion of injection, the piston 31 is returned back to a position of the origin. In a condition that the fuel passage 21a is thus interrupted, a minimum/maximum lift of the piston 31 is equalized, and in an ECU, when the minimum lift exceeds an upper limit lift threshold value, a fuel cutoff condition is judged. On the other hand, when fuel leakage is generated in a fuel supply route to the fuel injection valve, the minimum lift is prevented from being a lower limit lift threshold value or less, so generation of the fuel leakage is judged.

Title: Fuel injection pump having offset fuel injection cam shaft
Inventor: KUDO GOICHI
IPC: F02B3/06
Filed: 1991-08-26
Abstract: PURPOSE:To prevent an increase of a tuppet side pressure angle when an injection pressure reaches the maximum for a fuel injection pump in which a plunger is driven by a fuel injection cam through a roller tuppet by offsetting a fuel injection cam axial center to a tuppet roller axial center. CONSTITUTION:A plunger 2 is reciprocated through a tuppet roller 5 by rotation of a fuel injection cam shaft 6 interlocked with action of an engine of a diesel engine, so fuel sucked from a fuel passage into a high pressure chamber is boosted when the plunger 2 moves up to push and open a discharge valve 14 to be discharged to be supplied to a fuel injection nozzle. In this case, a fuel injection cam axial center 0 is disposed to be offset toward right to a tuppet roller axial center O1 for a predetermined quantity when the cam shaft 6 rotates clockwise, and toward left when it rotates counterclockwise. An increase of a tuppet side pressure angle is thus prevented when an injection pressure reaches the maximum so as to prevent fatigue breakage and avoid reduction of output heat efficiency.

Inventor: MATSUMOTO TAKUYA
IPC: F02D45/00
Filed: 1994-09-30
Abstract: PURPOSE: To enable deterioration judgement with high reliability to be carried out by judging deterioration of an exhaust cleaning catalyst based on outputs of two air-fuel ratio sensor provided upstream and downstream respectively from the exhaust cleaning catalyst, cancelling judgement of deterioration of the exhaust cleaning catalyst when deterioration of one of the air-fuel ratio sensors is detected.

Title: Sheet material feeder
Inventor: KAWARAMA MAKOTO
IPC: B65H7/04
Filed: 1993-08-30
Abstract: PURPOSE:To detect the remainder of sheet materials to be small before sheet materials loaded and stored in a sheet material storage part completely consumed. CONSTITUTION:A thin-wall thickness part 44c is provided on a sensor side lever 44b of a sheet material remainder detection lever 44 and when current value of light quantity in a transmission photomicro-sensor 45 for transmitting the thin-wall thickness part 44c reaches a prescribed value, the thickness and position of the thin-wall thickness part 44c is appropriately set so that the remainder of loaded sheet materials P is detected to be, for example, 100 sheets. If the device is so constituted that the remainder of the loaded sheet materials P is detected to be a few, the effect is informed to users by notification means such as lighting of a lamp or the like so as to urge supply of sheet materials. Therefore, just like in the cases of communication devices such as facsimiles, when power sheet supply is always put on and a user is not near the device, it can evade such a state of lacking in sheet materials.

Title: Grid pulser
Inventor: MASAKI TOSHIAKI
IPC: H05H7/08
Filed: 1990-09-07
Abstract: PURPOSE:To obtain an electron-gun emission current having a large number of pulse repetitions as well as to stably obtain the energy accelerated in an acceleration tube, by equipping the grid pulser with a large output high-frequency amplifier intended to amplify a CW signal and a bias voltage source causing increase in set level of the output from the large output high-frequency amplifier. CONSTITUTION:The CW signal generated from a CW signal generator 21 is converted into an optical signal by an optical driver 22 and is sent into an optical receiver 24 through an optical fiber 23. In the optical receiver 24, this optical signal is converted into an electric signal, the CW signal in the form of an electric signal being inputted into a large output high-frequency amplifier 25 and thus amplified. The CW signal thus amplified is inputted into a cathode of an electron gun 28 via a coupling condenser 26. This signal being inputted is in the form of a continuous wave whose level is uplifted by a voltage VB of a bias voltage source 27. Thus, an emission current of intermittent wave is generated in the electron gun 28. Since the cyclic period of this emission current is determined depending upon the frequency band of the amplifier 25, high repetitions are also possible.
