Filed: 1977-11-11
Abstract: PURPOSE: To reduce generation of poisonous gas by permitting normal combustion of air-fuel mixture at the time of the deceleration with a negative pressure control unit, which is used for an exhaust gas purifying system for automotive engines.  
     CONSTITUTION: When the manifold negative pressure exceeds a predetermined value at the time of the local deceleration, this negative pressure is led through a path 7 to a right chamber 5 in a differential valve 3 while it is also led through an orifice 8 to a left chamber 6. As a result, a pressure difference is produced across a diaphargm 4, causing the diaphragm 4 to be forced rightward against a spring 9 to open an atmospheric air inlet valve 2, whereby atmospheric air is introduced into a path 1 open to atmosphere and also to the intake manifold to prevent air-fuel mixture from becoming excessively rich. Further, the atmospheric air is led through check valves 12 and 14 to paths 11 and 13 to cause an EGR negative pressure path and a disboost negative pressure path to be opened to atmosphere. As a result, an ERG control valve is closed to stop circulation of the exhaust gas, thereby reducing the generation of poisonous gas.

Title: Pulse amplifying circuit
Inventor: KAWADA TOYOSHI
IPC: H03K5/12
Filed: 1981-08-27
Abstract: PURPOSE:To make a rise in output pulse voltage sharp and to suppress the generation of an induced pulse voltage, by connecting the input terminal of an up switching element to a power source for a higher power voltage than that of a  current supplying power source through a high resistance. CONSTITUTION:The input terminal of an up-MOST.Qu is biased by a power voltage VB supplied from a terminal 7 through a resistance RBG when a down- MOST.Qd is turned of, so the MOST.Qu is turned on and the potential at a point P1 never enters into a stray state, so that an output pulse voltage V0 has a value Vs invariably. Therefore, an induced pulse voltage by the elecdrostatic induction of a high pulse voltage is suppressed. Further, the voltage VB applied to the terminal 7 is set higher than the voltage VS applied to a terminal 3, so a rise of the output pulse voltage V0 varies according to the time constant determined by a resistance RG and a capacitor Cd is made shaper.

Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To solve collision in a short time in the case that incoming signals from pluralities of terminal equipments collide with each other in a 2-way cable communication system. SOLUTION: In the case of sending an incoming signal to a central controller, a terminal equipment stores an incoming signal in the inside, till the reception signal of a reply with respect to the incoming call signal is received from the central coefficient, or the number of times reaches a predetermined transmission number, the incoming call signal having been stored inside is repetitively sent to the central controller at a time interval decided depending on a random number generated based on a value specifically decided in the terminal equipment. Thus, even when incoming call signals from pluralities of the terminal equipments collide with each other, a timing when the incoming call signal is sent next from the terminal equipments is deviated and the collision of consecutive incoming call signals is avoided in a short time.
