Title: Fuel injection device for model engine
Inventor: MATSUDA NORIO
IPC: F02M51/08
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection device capable of preventing fuel leakage and providing good valve responsiveness. SOLUTION: The outlet 58 of a fuel supply passage is opened and the inlet 59 of an injection passage 56 is opened in a communication space 54 formed in one end surface of a valve box 51. A diaphragm 62 seals the communication space of the valve box 51. A valve body 70 driven by a solenoid coil 65 and the diaphragm are integral with each other. The valve body is pressed to the valve box side by a leaf spring 71. If no power is conducted to the solenoid coil 65, the leaf spring 71 presses the valve body 70 and the projection 64 of the diaphragm 62 closes the inlet 59 of the injection passage 56. No fuel is injected. If power is conducted, the valve body 70 is attracted to a magnetic core 66. The projection 64 is moved away from the valve box 51 and the injection passage 56 and the supply passage 55 are communicated by the communication space 54. Fuel is injected.  The valve body 70 receives no resistance from fuel during movement and thus only a small force is needed from the solenoid 65. Since fuel enters a casing 53, no fuel is leaked to the outside from a hole 69 for leading a power supply line 68 to the outside.

Title: Low voltage sample-and-hold circuit
Inventor: VALLANCOURT DAVID GERARD
IPC: G11C27/02
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To correctly operate a sampling circuit in a full range with a very low power source voltage by constituting the sampling circuit with a circuit which samples a voltage and holds the sampled voltage and a voltage boosting circuit boosting the voltage of the output of the sampling and holding circuit. SOLUTION: When a switch M1 is turned ON, an operational amplifier OA3 charges a holding capacitor CH. However, the ON threshold voltage of the switch M1 limits the voltage range of the signal to be transmitted from the OA3, for example, to be the interval 0 to 0.7 volt. When switches M2, M4 are turned ON, the node of the cathode of an output voltage boosting capacitor CS is charged to a level roughly equal to a reference voltage VX and the anode of it is charged to a level roughly equal to a very low Vsupply . Thus, a precharging circuit 100 boosts an output which is to be outputted from the switch M1 and whose voltage is 0 to 0.3 volt and which reaches a voltage level higher than the threshold voltage of a current storing MOS transistor M3.
