Title: Ac current control system in resistance welder
Inventor: OKATSUCHI CHIHIRO
IPC: B23K11/24
Filed: 1978-03-08
Abstract: PURPOSE: In phase control of a.c. current control gain for phase displacement is approximately calculated in about constant range by one time phase control or phase variation control in a given time, thereby performing a quick response control stable in a wide range.  
     CONSTITUTION: In a.c. current control circuit, standard current IR and load current I ac  are compared and calculated by the calculator 9 to obtain phase displacement according to gain coefficient K outputted by the gain changer 12. The controlled phase change is inputted into the phase shifter 11 through the phase variation controller 10. Output from the phase shifter 11 controls ignition phase of the electromagnetic valve 2. Meanwhile, from the phase shifter 11, another output is inputted into the gain changer 12 to change the gain according to plase angle. This circuit construction is such as to perform one time sampling control or one time control of phase variation, thereby enabling sequantial gain changes and calculations to result in stable operation.

Title: Electromagnetic-type fuel injection valve
Inventor: SHIRABE NAOTAKA
IPC: F02M51/06
Filed: 1987-02-09
Abstract: PURPOSE:To reduce the impact sound, by forming a hollow to avoid a receiving pin from contacting to a receiving connector, between the receiving pin and the receiving connector which are connected electrically to an electromagnetic actuator. CONSTITUTION:When a periodical electric signal is applied to an electromagnetic actuator 15 of an electromagnetic-type fuel injection valve main body 1, a valve member 8 repeates an injection and a stop while striking a valve seat 6 and a stopper 12 repeatedly. In this case, since mechanical impacts between metal parts are repeated, and metal impact sounds in a relatively high frequency range are generated, a hollow 30 to avoid a receiving pin 26 from contacting to a receiving connector 29 is formed between the receiving pin 26 and the insulating receiving connector 29 surrounding the receiving pin 26, to prevent such an impact sound from transmitting to the receiving connector 29 which functions as an antenna. In such a way, the impact sound released outward can be reduced without spoiling the fuel injection property.
