Title: Ripple regulator for intake air vacuum pressure of reciprocating engine
Inventor: GOTOU HEISHIROU
IPC: F02M35/10
Filed: 1980-12-25
Abstract: PURPOSE: To enhance durability and reliability in sensors and actuators, coupled to a lead-out port of intake air vacuum pressure, by providing, in a connecting port for introducing intake air vacuum pressure, a ripple suppressing regulator chamber of a conical space having an apex positioned at the connecting port.  
     CONSTITUTION: Intake air vacuum pressure which is introduced through an engine connecting port 4 and contains ripples, is effectively diffused in a conical regulator chamber 5 having a volumetric space and is interfered with reflective pressure wave reflected by the inner wall of the chamber 5. Further, the damping effect of the vacuum pressure is increased due to a sensor connecting port 6 having a small bore less than that of the connecting port 4 so that the regulated pressure wave is led out. Since the regulator chamber 5 is formed in a conical space, there are provided responsiveness enough for abrupt changes in intake air vacuum pressure and ripple suppressing effect. Since the conical regulator chamber 5 is effective for the diffusing but the volume thereof is not so large, errors of absolute values in detected intake air vacuum pressure is reduced. Reductions in ripple components and as well in irregular frequencies eliminate mechanical fatigue and thereby the durability of the sensors or the like is increased.

Title: Nonoverlap circuit
Inventor: ARIZONO TAKESHI
IPC: H03K5/151
Filed: 1986-08-04
Abstract: PURPOSE:To make an AND circuit unnecessary and to reduce the number of transistors by constiting a circuit of two three state inverters, one inverter and two pull-up resistances. CONSTITUTION:The pull-up resistances 13 and 14 with lower drive ability than that of the outputs L of the two three-state inverters 11 and 12 whose signal inputs are fixed at 'H' are connected to the outputs of said inverters 11 and 12. The control inputs of the inverters 11 and 12 are formed so that the one directly supplies a signal from an input terminal 1 and the other supplies a signal that the inverter 2 inverts the signal of the input terminal. Accordingly, the output terminals of the inverters 11 and 12 are always at L and at a high impedance according to the state of the control input. When the output of the three-state inverter shifts from L to a high impedance, the output terminal keeps L for a white, then slowly shifts to H. Consequently, the periods H of the two output never appear simultaneously.
