Inventor: MAEKAWA KOICHI
IPC: B60K17/04
Filed: 1985-07-15
Abstract: PURPOSE:To enable a smooth mobile cornering to be effected with the provision of the improved working efficiency by driving both a right and a left wheel through a disc type stepless transmission, the revolution of which can be switched over either to a normal or to a reverse rotation, and a differential gear successively. CONSTITUTION:Either a low speed or a high speed revolution can be obtained depending on the shifting of a driven disc 9B either to the inner side or to the outer side to the radial direction against a driving disc 9A of a stepless transmission 9, and moreover, the direction of revolution can be switched over either to a normal or to a reverse rotation by shifting the driven disc either to the right or to the left side of a rotating shaft center of the driving disc 9A. A running clutch 19 is provided for a rotating shaft 18 of the driven disc 9B. A right and a left wheel are driven by a differential gear 10 which is driven by way of the stepless transmission, where the rotating speed is made different between the right and left wheels while a vehicle is cornering enabling a smooth mobile cornering to be effected.

Title: Control circuit of electric shutter
Inventor: ISHIGURO YASUO
IPC: G03B7/00
Filed: 1979-12-03
Abstract: PURPOSE: To prevent troubles caused by the shutter which is left open, by making it possible to generate the closure control pulse twice to close the shutter surely.  
     CONSTITUTION: And gate circuit AG, one shot multivibrator circuits OSM3 and OSM4, and OR gate circuit OR 1  are added to the circuit of the conventional electric shutter provided with coils L 1  and L 2  combined with transistors T 1  and T 2 . When the output of OSM 2  is inverted to the H level while the output of OSM 1  is the H level, the output of AG is inverted to the H level; and when the output of OSM 1  is returned to the L level after 4ms, the output of AG falls to the L level also. The output of OSM 3  is inverted to the H level by this fall signal and falls to the L level again after a prescribed time. Consequently, the output of OSC 4  is inverted to the H level during 4ms by this rise signal and excites coil L 2  again through OR 1  to close the shutter.

Title: Defect-indicating apparatus on thin steel plate coil
Inventor: SAWADA YASUHIRO
IPC: G01N29/04
Filed: 1979-12-03
Abstract: PURPOSE: To permit the defect position on a steel plate to be readily discriminated without harming it mechanically and chemically by impressing a magnetic mark upon the defect position on a steel plate.  
     CONSTITUTION: Provided are flaw-detecting mirrors 4a and 4b, a magnetizer 5, a controller 6 for it, a pin-hole detector 7 and a steel-plate moving length detector 8. The pin-hole detector 7 comprises a light projector and a light receiver. The steel- plate moving length detector 8 comprises a magnetizer 8a, a magnetic mark detector 8b and a driver 8c. The magnetizer 8a impresses a magnetic mark upon a steel plate 1, and when the magnetic mark passes under the detector 8b, it sends a signal to the driver 8c. This actuates the magnetizer 8a to impress a magnetic mark upon the steel plate 1. After a pin-hole is detected by the pin-hole detector 7, the fact that the steel plate 1 has moved a certain distance is detected by reading the magnetic marks, and a magnetic mark is impressed upon the pin-hole position by the magnetizer 5.

IPC: H03B5/12
Filed: 1994-07-08
Abstract: PURPOSE:To improve power efficiency of a multiplied oscillation circuit by attaining an operation which oscillates by the frequency of a fundamental wave and an operation which amplifies the desired one of those higher frequency waves generated by the oscillating operation with a single transistor. CONSTITUTION:This oscillation circuit can perform both oscillating and amplifying operations by a single transistor TR Q1 in Colpitts oscillation form. Thus the 1st and 2nd circuit parts 12a and 13a consisting of the concentrated constant elements are connected to the emitter and the collector of the TR Q1. Then the output of a doubled frequency wave is taken out of the collector. Each of both parts 12a and 13a consists of a coil and a capacitor, and the tuning frequency of parts 12a and 13a are set at f0 and 2f0 respectively. Thus the emitter and collector have high and low impedances respectively with the frequency f0 and vice versa with the frequency 2f0. In such a constitution, a collector-grounded Colpitts oscillator is secured to a basic wave of frequency f0 and an emitter-grounded amplifier is secured to the double wave respectively. Then the doubled frequency wave existing at the base of the TR Q1 is amplified and outputted from the collector.

Title: Method for controlling pulse electrification of electronically controlled fuel injection device
Inventor: ISHIDA KATSUMI
IPC: F02D41/04
Filed: 1988-06-24
Abstract: PURPOSE:To carry out the stable control of the maximum fuel quantity injection by reducing the frequency of a valve-opening time control at the time of the electrifying time reaching the maximum flow rate side non-linear zone of an electronically controlled fuel injection device. CONSTITUTION:In an electronic control device 9, it is judged whether the valve opening time of an injector 4 is within the maximum valve opening time of a linear zone determined by a driving frequency at that time. At the time of exceeding the maximum valve opening time, since a non-linear zone is defined time width unaffected by the driving frequency, the driving frequency is reduced. This reduced frequency of valve opening time control is such a value at which a fuel injection starting timing is not selectively synchronized with the intake stroke of any of cylinders or cylinder groups. Thereby, the proportion of the linear zone of pulse electrification for a driving period is increased in the specific cylinder or cylinder group and, as a result, it can be prevented to use the non-linear zone in a valve opening time which is varied in accordance with the driving frequency. Hence, a required quantity of fuel can be accurately injected.
