    摘要: Disclosed herein is an evaporative emission control system which can prevent changes in fuel component in the fuel tank and vacuum boiling in the fuel pump to thereby accurately control the air-fuel ratio to a desired value and ensure smooth supply of the fuel. The control system includes an evaporative fuel passage for connecting a fuel tank and an intake system of an internal combustion engine, and a control valve is provided in the evaporative fuel passage for opening and closing the evaporative fuel passage. It is determined whether or not a fuel temperature is higher than or equal to a predetermined fuel temperature. If the fuel temperature is higher than or equal to the predetermined fuel temperature, the opening operation of the control valve is disabled.

    摘要: In each sampling period, sample data and a count value WA of a ring buffer counter 11 are supplied to a RAM 202 through a bus control circuit 14 as write data and a write address. Each cache block stored in a data buffer DB.sub.0 and so on is used for executing an FIR filtering operation. As an amount of unused sample data in the cache block is decreased, subsequent cache blocks used for a subsequent FIR filtering operation are supplemented to the data buffers DB.sub.0 and so on by the cache counter units CC.sub.0 and so on.

    摘要: A shallow groove isolation structure (SGI) electrically insulates adjoining transistors on a semiconductor substrate. A pad oxide film is formed on the semiconductor substrate and an oxidation inhibition film is formed on the pad oxide film. Parts of the oxide inhibition film and pad oxide film are removed to form the groove. In particular, the pad oxide film is removed from an upper edge of the groove within a range of 5 to 40 nm. A region of the groove is oxidized in an oxidation environment with a cast ratio of hydrogen (H.sub.2) to oxygen (O.sub.2) being less than or equal to 0.5. At this ratio, the oxidizing progresses under low stress at the upper groove edges of the substrate thereby enabling rounding of the upper groove edges without creating a level difference at or near the upper groove edge on the substrate surface.

    摘要: An air-fuel ratio control system for an internal combustion engine includes an air-fuel ratio sensor arranged in the exhaust system of the engine. An ECU determines activation of the air-fuel ratio sensor and carries out feedback control of the air-fuel ratio of a mixture supplied to the engine in response to the output from the air-fuel ratio sensor. An intermediate state of the air-fuel ratio sensor corresponding to a transient state of the air-fuel ratio sensor from an inactive state thereof to an active state thereof is determined. The output from the air-fuel ratio sensor for use in execution of the feedback control is corrected when the air-fuel ratio sensor is in the intermediate state.

    摘要: A push button switch covering member of a silicone rubber is imparted with excellent resistance against stain deposition and abrasive wearing by providing a protective overcoating layer of a urethane resin-based coating composition capable of being cured by forming urethane linkages between isocyanate groups of a polyisocyanate compound and hydroxy groups of a polyhydroxy compound. The coating procedure with the coating composition on the surface of a silicone rubber-made covering member is preceded by a plasma treatment so as to activate the surface resulting in an increased adhesive bonding strength between the silicone rubber body and the coating layer. The improvement is more remarkable when the plasma-activated surface is subjected to a priming treatment with a silane coupling agent and coating with the coating composition is undertaken as soon as possible or within 60 minutes after completion of the plasma treatment.

    摘要: In a TV signal encoder device comprising, for encoding a digital TV signal into an encoder device output signal, both having a predetermined dynamic range, an amplitude limiter, a predictive encoder unit for predictive encoding with quantization an amplitude limited signal of a limited dynamic range into a quantized signal having together with quantization noise the predetermined dynamic range, and a code converter for code converting the quantized signal into the device output signal, a forward offset circuit adaptively gives a forward shift to the TV signal so as to avoid undesirable clipping of tip ends of synchronizing signals in the amplitude limited signal. The forward shift and a lower and a higher range reduction of the predetermined dynamic range into the limited dynamic range are preferably equal to a maximum quantization noise level. Instead of the offset circuit, use of an encoder dynamic range defining circuit is more preferred. In this event, a TV signal decoder device comprises instead an inverse offset circuit a decoder dynamic range defining circuit and a level converter.
