Title: Controlling method for air-fuel ratio of gas engine
Inventor: FUJIMOTO HIROSHI
IPC: F02M21/02
Filed: 1989-12-15
Abstract: PURPOSE:To enhance the purifying characteristic of a gas engine for a sudden change in loads, by temporalily stopping feedback control of air-fuel ratio if a sudden change in loads is detected, and also finding the rate of opening of a control valve corresponding to loads after the sudden change as a value of having corrected a set value of a reference table. CONSTITUTION:A gas engine has a control valve 3 provided with a passage around a mixer 2, the rate of opening of the valve 3 being controlled by a controller 4 in response to the output signals of an O2 sensor 1, a temperature sensor 8 and a load sensor 9. In this case, the relation between the load of the gas engine 5 and the rate of opening of the control valve 3 is preset as a reference table 10 and is stored in memory in the controller 4. Also, a correction table 11 is provided for taking into account the influence of environmental changes. When a sudden change in loads is detected, feedback control of air-fuel ratio is temporalily stopped and the rate of opening of the control valve 3 corresponding to loads after the sudden change is found as a value of having corrected the set value of the reference table 10 according to the corrected value of the correction table 11.

IPC: H02K41/025
Filed: 1990-11-27
Abstract: PURPOSE:To reduce manpower and enhance efficiency in fabrication and to facilitate miniaturization of motor by applying a coil in each tooth and then connecting the coils in three-phase. CONSTITUTION:In a linear induction motor 1, teeth 3a, 3b... are formed in a primary core 2 with a constant pitch and coils 4a, 4b... are applied in respective teeth 3. In other words, a coil 4 is applied in each tooth 3 and then the coils 4 are connected with a power supply in the order of U, V, W or U, W, V thus connecting the coils in three-phase. Since a tooth is not applied with a plurality of coils, the coils can be applied in a large number of teeth simultaneously with high efficiency. Furthermore, coil end of each coil can be made small as compared with double layer winding in which the coil is applied in a plurality of teeth, resulting in miniaturization of motor.

Abstract: PURPOSE: To provide a stool cleaning switch valve, easy to assemble and inspect for maintenance, in a simple structure and at a low cost by arranging a flow passage switching flap valve in the switch valve body with two outflow water passages. CONSTITUTION: When an operating handle is rotationally moved, water reserved in a tank is supplied to a rim water pathway in a stool body to start cleaning of a stool bowl, and when a water level in the tank is lowered, water is supplied from a ball tap. The supplied water flowinng into a water supply port 15 in a switch valve 11 is supplied from the first outflow port 12 through a flap valve 16 into a jet hole in the stool body to give syphon effect thereto.

Title: Instruction counter control system
Inventor: WATABE TORU
IPC: G06F9/26
Filed: 1988-12-27
Abstract: PURPOSE:To decide the branch of a microinstruction in a single step by inhibiting the update of a zero-stop counter in the case the value obtained before a count-down action is equal to zero even though the count-down action is carried out with a microinstruction. CONSTITUTION:A zero-stop counter 4 is used not to count any more when the count value is once equal to zero. This counter 4 can be controlled by a microinstruction, and a control circuit 3 controls the branch of the microinstruction. For instance, the microinstruction read out of a microinstruction holding memory 1 is once held in a microinstruction output register 2. Then the circuit 3 works in response to the held microinstruction. In this case, the circuit 3 checks whether the count value of the counter 4 is equal to zero or not as long as the microinstruction instructs to write 4 bytes, for example, into a memory. When the count value of the counter 4 is equal to zero, a 3-byte writing routine is through. Thus the branch of the microinstruction is decided in a single step only.

Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To emit high-quality illuminating light for a large screen by forming a primary light source of plural fluorescent lamps whose length is selected so that non-light emission areas may not be superposed on each other in an area distant from the end of an end face. SOLUTION: The primary light source 12A is formed by surrounding eight fluorescent lamps 14AA, 14AB, 14BA and 14BB of four kinds having different length by a reflector 13A. The length of the lamps 14AA, 14AB, 14BA and 14BB is selected so that it may not exceed the length of the fluorescent lamp applied to the conventional sidelight type surface light source device. Thus, the primary light source 12A is constituted so that the lamps 14AA, 14AB, 14BA and 14BB are driven by lighting start voltage. Therefore, the incident light quantity is prevented from being locally lowered in the area distant from the end of an incident surface, so that the sufficient illuminating light is supplied by plural lamps 14AA, 14AB, 14BA and 14BB.
