Title: Fuel injection device for engine
Inventor: NAKAMURA SETSUO
IPC: F02M69/04
Filed: 1990-01-30
Abstract: PURPOSE:To prevent fuel left and adhered to an atomizing means from flowing out to the engine side by vibration by controlling the atomizing means, disposed in the vicinity of the nozzle of an injector, to stop its vibration during the fuel cutoff of the injector. CONSTITUTION:An atomizing means 4 and an injector 3 provided at an intake manifold 2 in the vicinity of a cylinder head 1 are connected to a control unit (ECU) 5, and the vibrator 41 of the atomizing means 4 and the fuel injection quantity of the injector 3 can be controlled by signals from the ECU 5. In case the fuel injection of the injector 3 is stopped by this control means, the vibration of the atomizing means 4 is stopped correspondingly. As a result, even if fuel is left and adhered to the atomizing means 4, such an existing problem as to further atomize this fuel or to feed the residual fuel around the injector 3 to the engine side by vibration can be dissolved.

Title: Electronic component
Inventor: SHIMIZU ICHIRO
IPC: H01L23/48
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To cause solder break at straight leads and prevent solder break at non-straight leads by forming the portions of the leads of an electronic component which come to the part side of a mounting board so that the portions comprise combinations of parts different in shape. SOLUTION: A hole 8a is for installing an electronic component 8 on a holding member (heat sink or the like), and lead impact absorbing portions 9b and 10b are different in shape from lead straight portions 9a and 10a to be joined with the main body 8. If an impact load is exerted on the electronic component 8, displacement of the component does not act direct on solder and is divided and absorbed by the impact absorbing portions 9b and 10b. If any displacement in the component is directly transmitted, the solder is apt to break. In this constitution displacement is absorbed here and can be limited to within the allowable stress of the solder, and the solder can be prevented from breaking. These shapes of leads can be easily obtained by stamping and have no influences on component cost.

IPC: H04L25/02
Filed: 1982-02-10
Abstract: PURPOSE:To attain a circuit having strong performance against noise on a transmission line and less power consumption with high reliability, by detecting the leading and trailing of a transmission digital signal, transmitting the pulse and reproducing the signal as a reception digital signal with a flip-flop element. CONSTITUTION:When a transmission signal is inputted to an input terminal 1, a trigger detection element 7a catches the leading and generates a pulse. Since a transistor (TR) 82a is set on with this leading pulse, a capacitor 83a is discharged, a charge is supplied from a point B of a pulse transformer 86 to a point A of the 86, a transmission line 85a, a diode 84b, a diode 84a and ground. A TR82d is turned on when a voltage reaches the Zener voltage of a Zener diode 89b with a delay by the time constant of an integration circuit element 88. In this case, since a leading pulse is lost, the TR82a is set off and the capacitor 83a is charged up as the initial state.
