Title: Intake air quantity controller for electronically regulated fuel injection engine
Inventor: NAKANO JIROU
IPC: F02D41/34
Filed: 1979-04-27
Abstract: PURPOSE: To control the quantity of intake air which is bypassed through a throttle valve and to keep the rotational frequency of idling constant, by rotating a centrifugal governor mechanism in accordance with the rotational frequency of an engine and opening or closing the variable orifice of a valve mechanism.  
     CONSTITUTION: When the fall in the rotational frequency of idling due to the action of an air conditioner or the like during the idling is detected by a sensor provided in a distributor 24, a centralized controller 21 supplies a driving signal to the DC motor 40 of an intake air quantity controller 30 installed in a bypass pipe 28 for bypassing throttle valve 14 in an intake pipe 11. When the motor 40 is rotated, a valve 34 having a variable orifice 35 is opened through the medium of the pivot shaft 39 of the valve 34 by the centrifugal action of a governor mechanism having a weight 37. As a result, the quantity of intake air increases to produce the same effect as the case that the throttle valve 14 is opened. The rotational frequency of idling is thus kept constant.

Abstract: PURPOSE:To attain a high-speed input of the picture data of large capacity by transferring the read data sent from plural bit lines in parallel to each stage of a shift register or supplying the data of each stage of the shift register in parallel to plural bit lines. CONSTITUTION:For a normal random access operation, a word line is selected by a word decoder 2 and at the same time a bit line is selected by a column decoder 3, respectively. Then the data is read out of a memory cell MC which is set at the intersecting point between said word line and the bit line. Otherwise this data is written. These read/write operations are switched by switching the internal circuits of an input/output gate 4 with a write enable signal. When the data is written, the input data DIN is supplied to a selected bit line. Then the read signal sent from a selected bit line is amplified by a sense anplifier within the gate 4 and extracted as the data output DOUT when the data is read out. Thus a random access operation is possible independently with no disturbance due to a data output operation.
