Title: Oil returning device of horizontally opposed internal-combustion engine
Inventor: YAMAKAWA TOORU
IPC: F01M13/00
Filed: 1981-12-26
Abstract: PURPOSE:To improve the returning of oil, by forcibly returning the oil in a crank chamber bottom plate to an oil pan through a one-way air flow generated by utilizing pulsating pressure. CONSTITUTION:Two sets of crank chambers 22a, 22b, in which two front cylinders 4a, 4a' correspond to two rear cylinders 4b, 4b', are air-tightly formed in a crank case 1 by a bottom plate 19 and metal housing 21. Accordingly, at operation, back pressure of two pistons 5a, 5a' and 5b, 5b' performing the same reciprocating motion, that is, negative pressure at transfer movement to the top dead center and positive pressure at transfer movement to the bottom dead center are generated in each chamber 22a, 22b to cause largely changing pulsating pressure. At operation, a check valve 26 is opened by this negative pulsating pressure in the chamber 22a to introduce fresh air to the chamber 22a. The pulsating pressure is in a phase 180 deg. different and returning of oil is alternately repeated. Meeting this action, a forcibly returning amount of the oil can be increased.

Title: Gas meter
Inventor: NUKUI KAZUMITSU
IPC: F16K17/36
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a gas meter in which a gas flow passage can be shut off quickly by a shutoff valve after an earthquake has been sensed, which can detect a very small gas leak and in which the shutoff valve can be returned automatically when a gas leak does not exist. SOLUTION: When a seismoscope 16 is operated, a safety function part 22 controls a shutoff-valve drive circuit 23, it sets a shutoff valve 13 to a shutoff state, and it shuts off a gas flow passage so as to inspect a gas leak. When it is detected that the gas leak does not exist as a result, the shutoff valve 13 is set to a return state. When it is detected that the gas leak exists, the shutoff valve 13 is set to the return state after a prescribed standby period has elapsed, and the gas leak is inspected again in the state. When it is judged that the gas leak does not exist as a result, the return state of the shutoff valve 13 is maintained. When it is judged that the gas leak exists, the shutoff valve 13 is set to the shutoff state.

Abstract: PURPOSE:To unnecessitate an insulation adhesive by isolating external leads from a heat dissipator in mechanical and electrical manner by a method wherein an electronic component assembled structure with an element body adhesion-fixed in a recess from working part of a lead frame and the heat dissipator joined to the back surface of the part is formed with a mold resin into an integral body. CONSTITUTION:Using the one having an element adhesion part 8 worked into a recess from as the lead frame 1, the back surface of the element adhesion part 8 is adhered on the heat dissipating block 2 by means of a solder 9 of a lower melting point than that of a solder 5, after the element 4 is adhesion-fixed on the bottom surface of the element adhesion part 8 by means of the solder 5. Next, the electronic component assembled structure is obtained by electrically connecting the electrode of the element 4 to the external lead by means of metallic fine wires 6, which is then molded by sealing with the mold resin 7 into an integral body. Thereby, the adhesion surface of the lead frame for the heat dissipating block 2 projects downward; therefore there is no possibility that the other part of the lead frame contacts the heat dissipating block 2, and then it becomes unnecessary to adhere the heat dissipating block to the lead frame with an electric insulation adhesive.

Abstract: PURPOSE:To cut the supply of external noise and the like to attain stable modulation by providing a switching diode in a forward direction with respect to an input signal for the prestage of a signal supply means, and supplying the input signal to the signal supply means through the switching diode. CONSTITUTION:An inverse direction voltage is impressed on a varactor diode 2. when the pulse wave of 5V, for example, is inputted from an input terminal Ti in such a state, the static capacity of the varactor diode 2 is changed. Thus, a system is made to a state that modulation by an SAW resonator 6 provided in a subsequent level, furthermore, a transistor 1 is attained. When the external noise of about 1.2V is inputted, there is hardly any output from the switching diode 4. Consequently, noise is hardly supplied to the varactor diode 2. Thus, the static capacity of the varactor diode 2 can stably be controlled, and modulation by the SAW resonator 6 and the transistor 1 provided to the next stage can stably be executed.
