IPC: F02D41/14
Filed: 1981-10-26
Abstract: PURPOSE:To promptly start feedback control after ending warming of an engine, by detecting a rise of cooling water temperature to at least a prescribed value from a value at starting of the engine. CONSTITUTION:In an electronic controller 40, in which signals of an air flow meter 2, water temperature sensor 30, air-fuel ratio sensor 31, etc. are input to control a fuel injection valve 41, firstly cooling water temperature at starting is stored by an input from the sensor 30, then the present cooling water temperature is detected, if a difference between the both temperatures is in a prescribed value or more, a feedback control start flag is set. That is, considering a feedback signal from the sensor 31, the valve 41 is controlled. In this way, an increase amount of cooling temperature, relatively correctly corresponding to a process of engine warming, can be utilized for a start of feedback control, then efficiency of fuel consumption and purification of exhaust gas can be improved.

Title: Forming method for solder coating layer on lead
Inventor: YOKOYAMA TAKAAKI
IPC: H01G13/00
Filed: 1988-07-08
Abstract: PURPOSE:To form a thin and uniform solder layer on the outer lead of an electronic component by bringing part of solder adhering to the lead and connecting stripe into contact with solder in a recess. CONSTITUTION:An electronic component assembly 11 is moved longitudinally in a state that the edge of a first connecting stripe 15 remains in contact with the bottom 24a of a recess 24 to bring the edge of the stripe 15 into contact with the bottom 24a of the recess 24 over its whole length. Thus, solder 22 adhering thickly to the stripe 15 is sequentially brought into contact with the solder 22 in the recess 34 to be contained in the recess 24. The solder 22 contained in the recess 24 flows from the recess 24 by moving the assembly 11. Thus, part of the solder 22 adhering to the stripe 15 can be removed. In this manner, part of the solder 22 adhering to a first outer lead 13 flows to the stripe 15 thereby to reduce the thickness of the solder 22 adhering to the lead 13 and make it uniform.

Filed: 1993-07-09
Abstract: PURPOSE:To reduce power consumption at the time of preceding standby operation by opening a delivery valve to start a motor after residual water in a delivery pipe is drained from a drain system. CONSTITUTION:In a motor-driven preceding standby operating pump, at the time of stopping operating a pump 2 by closing a delivery valve 8 to stop a motor 13, from a slight clearance between an opening part 9A of a delivery pipe 9 and a reverse flow preventing valve 11, water in a delivery water tank 10 flows in the delivery pipe 9, to generate a condition that water is left in the inside of the delivery pipe 9. Accordingly, a drain valve 16B is opened before starting a preceding standby operation. In this way, residual water W in the delivery pipe 9 is drained to a feed water well 1 through a drain pipe 16A. Consequently, by opening the delivery valve 8 after draining the residual water W in the delivery pipe 9, even when the motor is started, no large load is applied to an impeller 5, main shaft 4 and the motor 13. That is, the preceding standby operation can be realized in an aerial operation condition of small load.
