Abstract: Throttle valves are individually disposed in a plurality of intake passages of an engine. In normal operation condition of the throttle valves, a first control device controls the throttle valves according to the detection result of an operation condition detecting device to control the amounts of intake air of the individual intake passages, thereby obtaining good engine performance from low-speed to high-speed ranges. When an abnormality detecting device detects an abnormality in a throttle valve, a determination device determines a normal throttle valve, and a second control device controls only the normal throttle valve in preference to the first control device to control the intake air amount, thereby ensuring continued operation even if a malfunction occurs in one of the throttle valves.

Abstract: A segmented pipe coupling provides a housing for a butterfly valve, and preferably is provided with oppositely angled end faces of saw tooth configuration at the respective ends of the coupling segments, thus allowing the inclined end faces to emerge at the axial end faces of the coupling at or closely adjacent to the X-Z plane of an axially long coupling. A slow motion rotary drive for the butterfly valve also is provided.

Abstract: A pipeline coupling comprises first and second substantially annular connecting pieces at each end of a length of pipe, an internally threaded nut on the first connecting piece and a corresponding external thread on the second connecting piece, and a sealing ring for location between adjacent ends of two lengths of pipe to be connected, a sealed connection between the two lengths of pipe being effected by screwing the nut onto the external thread to draw the connecting pieces axially towards one another and to compress the sealing ring therebetween. A substantially annular locking ring is mounted on the second connecting piece to be axially movable therealong but rotatably fixed relative thereto, the locking ring and nut being provided with corresponding projections and recesses adapted to engage with one another to prevent relative rotation between the two connecting pieces, releasable means retaining the projections and the recesses in engagement with one another.
Abstract: An automatic assembly device includes a jig pallet for carrying and positioning parts used in an assembly line, and a holding device for holding fastener members used to mount the parts to assembled members. A drive is positioned between the fastener member holding device and an external driving device.
Abstract: The described hearing aid includes a frequency analyzer for classifying incoming sounds according to their frequency, and for selecting an appropriate transposition factor (the ratio of the information storage rate to the information retrieval rate) according to the appropriate one of several transposition factors inputted into the hearing aid based on the particular user's hearing characteristics for different frequencies. Also, described is an arrangement for minimizing loss of speech components containing the same frequency information by recirculating such speech components. Further described is an arrangement for reconstructing portions of the speech components according to their classification by the frequency analyzer in order to minimize loss of useful information in the output signal.
Abstract: A stalling preventing appartus for an engine comprising intake air amount increasing means for increasing the amount of intake air to the engine from idling condition when the vehicle is in a start preparation condition, and rotation speed increase prevention means for preventing the engine speed from increasing due to the increase in intake air amount by the intake air amount increasing means, operation of the intake air amount increasing means and the rotation speed increase prevention means being stopped when the vehicle is in a start preparation condition, whereby a sufficient amount of air is supplied to the engine at starting of the vehicle and a delay in response of the air intake system to the pressing-down operation of the acceleration pedal is eliminated to increase the output torque of the engine at clutch-on and prevent engine stalling.
Abstract: Disclosed is a method for controlling the quantity of intake air supplied to an internal combustion engine, in which the position of a valve member of a flow control valve having a non-linear valve opening characteristic is converted into an intake air quantity or a virtual valve position proportional to the intake air quantity so as to linearize the non-linear valve opening characteristic of the flow control valve. Application of the method of the present invention to an idle speed control device in an engine equipped with an electronic controlled fuel injection system is advantageous in that the quantity of intake air supplied to the engine can be accurately controlled under various operating conditions of the engine, therely preventing rotation of the engine at an excessively high speed and stalling of the engine, improving the fuel consumption and reducing noise generated from the engine.
