IPC: F02D41/34
Filed: 1980-10-27
Abstract: PURPOSE: To maintain a mixture ratio at an prescribed value even if a throttle valve is suddenly changed by compensating an output pulse width with a degree of opening of said valve in an electronically controlled fuel injection device which operates said pulse width with an output of a heat ray type air flow.

In case the degree of opening of the throttle valve increases above a prescribed value, compensation is made through an increment in deceleration of the output pulse width. In case said degree reduces below said value, compensation is made through an increment in acceleration of said width. Accordingly, a  change of a mixed ratio due to an abrupt change of a degree of opening of the  throttle valve may be prevented, responsiveness at acceleration improved, and mis- firing as well as a phenomenon of gas flickering at deceleration may be also  prevented.

Title: Screen distortion correcting circuit
Inventor: NISHIMURA HIROAKI
IPC: H04N3/223
Filed: 1988-06-20
Abstract: PURPOSE:To correct the fluctuation of the screen size caused by the light/ darkness of a screen by using both an FBT(flyback transformer) containing b beam current detecting terminal used to a luminance limiting circuit and a PCT(pincushion transformer) for correction of pincushion distortions. CONSTITUTION:The collector current of a transistor 14 flows to a winding set at the vertical (primary) side of a PCT 20 via a resistance 16. When the collector current decreases, the inductance of a winding set at the horizontal (secondary) side of the PCT 20 increases. As a result, the ICP decreases. Then the horizontally deflected current flowing to a horizontally deflected coil 5 is decreased. Thus the horizontal size of a screen is also decreased. While the ICP increases when the screen becomes dark, i.e., the beam current decreases. Thus the screen size is increased. As a result, the horizontal size of the screen can be kept constant.
