Title: Device for controlling air-fuel ratio of engine
Inventor: MATSUKI MITSUO
IPC: F02D41/00
Filed: 1988-04-20
Abstract: PURPOSE:To reduce a wasteful time at the time of change of air-fuel ratio and quicken the responsiveness to control by selecting the output of an air-fuel ratio detecting means provided in the close position to an exhaust port when judged to be the transient time of an engine. CONSTITUTION:In the exhaust system of an engine 7, a first air-fuel ratio detecting means 9 composed of an air-fuel ratio sensor is provided on an exhaust manifold 8, in the vicinity of the exhaust port of one cylinder while equally providing a second air-fuel ratio detecting means 10 on the collecting portion 12 of the exhaust manifold 8. A control unit 13 detects the change in a throttle opening from a throttle opening detecting means 2 and judges whether or not the engine 7 is in a transient condition and outputs a selecting signal. Thereby, when judged to be in the transient time, the output value of the air-fuel ratio detecting means 9 is employed. Hence, the smaller value in the wasteful time of the air-fuel ratio detecting means 9 serves to increase a following property which is important for improving the accuracy of feedback when an air-fuel ratio is suddenly changed at the transient time of acceleration/deceleration, etc.

Inventor: MATSUNAGA SHIYOUICHI
IPC: F16K21/18
Filed: 1979-08-01
Abstract: PURPOSE: To secure a constant flow valve with good flow regulating characteristic by making the valve element for said check valve to be used in a flow control line in a plastic resin with smaller specific weight than that of water, which will assure that the valve be opened and closed in response to a slight differential pressure.  
     CONSTITUTION: In case the valve element 6 is open, and the water flowing from the flow-in chamber 2 to flow-out chamber 3 through the port 5 has the set value, the pressure in pressure room 15 which is to press down the valve element 6, balances with the one in flow-in chamber 2 which is to push up the valve element 6, whereby the vavle element 6 holds a certain intended opening to maintain the intended rate of flow. The valve element 39 of a check valve 35 in the flow control passage 34 is made of a plastic resin with smaller specific weight than that of water and sits on a downwardly facing valve seat 37 by the action of the buoyancy. This opens and closes the check valve 35 in response to the slightest pressure difference between the pressure chamber 15 and flow-in chamber 2. Thus, the valve opening is regulated securely by lifting up and down the valve element 6 according to the flow speed, and the rate of flow is held at the intended value.

Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a compact, low-cost three-phase motor drive equipment capable of preventing accidents due to overoperation by contact welding of an operation relay for three-phase motor driving a target accompanying a danger. SOLUTION: A three-phase motor 10 drives a pump 11 pressuring a combustible gas as a target accompanying a danger. Among the three-phase powder supply 17 driving the three-phase motor 10, a cable way 18A for single-phase is closed normally or before the operation of the three-phase motor 10 by means of a first relay circuit 161. Cable ways 18B and 18C of the remaining two phases of the three-phase power supply 17 are opened and closed at each operation/stop of the three-phase motor by a second relay circuit 162. When the second relay circuit 162 is open, an overoperation detecting circuit 20 detects the presence or absence of the overoperation, if there is any overoperation, the first relay circuit 161 is opened and the overoperation is stopped.  Detection of the overoperation can be achieved by the presence or absence of a voltage between two-phase cable way 18B and 18C and single-phase cable way 18A, or the presence or absence of currents in the two-phase cable ways 18B and 18C. The relay circuit 162 can have a configuration capable of closing and opening the contacts a and b with other relay.
