Title: Starting of air-fuel ratio control of internal-combustion engine
Inventor: IWANO KAZUHIKO
IPC: F02D41/14
Filed: 1982-11-15
Abstract: PURPOSE:To improve the idling stability at re-starting under high temperature by a method wherein the feedback control is started at high temperature regardless of the output state of an oxygen sensor in a system, in which the air-fuel ratio is feedback- controlled when the oxygen sensor detects the rich state in air-fuel ratio. CONSTITUTION:During the running of an engine, an electronic control unit (ECU) 38 calculates base fuel injection amounts based upon the outputs of an air flow meter 12 and an turning angle sensor 32. In addition, said base fuel injection amounts are corrected by the outputs of a water temperature sensor 34 and the like, and when feedback condition is established or a rich signal is outputted from an oxygen sensor 26, the air-fuel ratio is feedback-controlled in response to the condition whether the state of the exhaust air-fuel ratio detected by the oxygen sensor 26 is rich or lean. Furthermore, in this case, when an engine is in the high temperature state such as more than 100 deg.C judged by the output of the water temperature sensor 34, the operation is started to be feedback-controlled regardless of the output state of the oxygen sensor 26, resulting in improving the idling stability especnially at re-starting under high temperature.

Abstract: PURPOSE:To improve the reliability of a system by providing the 2nd array logic having an input NOT circuit and an output NOT circuit in parallel with the 1st array logic, comparing logical output values of both array logics and transmitting an output inhibiting command when they are not coincident. CONSTITUTION:A logical multi-input 100 is applied also to an array logic 8 in parallel with an array logic 3 via a logical NOT circuit 5. The logical arithmetic written in the logic 3 in advance is executed for the input 100 by an AND array 1 and an OR array 2 and a logical multi-output 103 is obtained. The logic 8 is programmed in an AND array 6 and an OR array 7 forming the logic 3, and the circuit 5 so as to satisfy the De Morgan's theorem to the array 3. Thus, the logical multi-outputs 102, 103 are in the relation of the logical NOT and the logical value of the logical outputs 102, 104 is coincident with each other. If they are not coincident, an output inhibiting command 105 is outputted to an output gate 11.

Title: O-ring for sealing and manufacture thereof
Inventor: MOTOYA MASAKATSU
IPC: F16J15/08
Filed: 1993-07-23
Abstract: PURPOSE:To prevent a metal O-ring for sealing from being plastically deformed at high temperature into loss of elasticity. CONSTITUTION:This O-ring for sealing is constituted so that expansive graphite 2 is filled in the hollow part of a metal O-ring member 1 in high density. Hereby, the expansive graphite exhibits rubber elasticity at being in high density. By this constitution, elasticity of the metal O-ring member 1 at high temperature is held with the expansive graphite 2 in the interior. Because the expansive graphite tightly closed with the metal 0-ring member 1 does not directly come in contact with air, no oxidation loss is generated, and elasticity is maintained at high temperature as it is.
