    摘要: A magnetic head assembly of a disk drive device has an upper magnetic head fastened to a case side and a lower magnetic head mounted on a gimbal plate of a carriage side. The upper case assembly includes a plurality of leaf hinge springs extending to the vicinity of the upper magnetic head, which is bonded to a supporting plate, and wire leads from the magnetic head are soldered to the leaf hinge spring ends as lead terminals. The other ends of the leaf hinge springs extend to the rear side of the case and serve both as a pivotable hinge mounting of the case to the carriage and as lead terminals to an external read/write controller. The upper case assembly is formed by molding in resin a flat plate which is precut with the leaf hinge spring and supporting plate portions formed in a predetermined shape, cutting the flat plate thus insert molded to separate the plate and a plurality of lead terminals independently, fastening the upper magnetic head to the plate, and connecting the lead wires from the fastened magnetic head to the predetermined divided lead terminals. Thus, the magnetic head assembly can be accurately manufactured inexpensively.

    摘要: Method and apparatus for sensing liquid level of the invention includes a plurality of thermocouple elements that are formed by connecting two kind of thermocouple wires alternately in series into a plurality of thermometric contacts. The two kind of thermocouple wires have different thermoelectric powers SA and SB and have a variety of predetermined lengths. The invention can sense with high reliability a liquid level of a sensed liquid by changing electromotive forces from these thermocouple elements into binary signals by using fewer thermocouple elements than the conventional apparatus. The invention also includes thermocouple elements for parity check to self-diagnose the sensed result to inspect easily and securely errors in operation due to disconnections in the thermocouple elements or external noises.

    摘要: A carrier is amplitude modulated in an amplitude modulator by a train of unipolar signals which alternately assume a definite voltage level and an arbitrary amplitude of one polarity. Either the carrier before it is modulated or the modulated carrier is phase modulated by the train of unipolar signals. The phase modulation takes place cyclically in that modulated carrier assumes one of predetermined N discrete phases for each occurrence of the unipolar signals. On the receiving side, the received signal is subjected to an envelope detection to extract envelope information.

    摘要: An exhuast gas purifying apparatus for use in an automobile multi-cylinder engine of the type which has exhaust ports communicating with engine cylinders and through which exhaust gases are emitted subsequent to combustion of an air-fuel mixture. The exhaust gas purifying apparatus comprising a reducing catalyst unit and a three-way catalyst unit which are disposed in a main exhaust manifold which is connected at one end to a first group of the exhaust ports and at the other end to the atmosphere, and an auxiliary exhaust manifold connected at one end to a second group of the exhaust ports and at the other end to a portion of the main exhaust manifold at a location downstream of the reducing catalyst unit and upstream from the three-way catalyst unit. A pressure operated valve is disposed in a secondary air supply passage for introducing a secondary air into the auxiliary exhaust manifold by the utilization of the pulsating flow of the exhaust gases through the auxiliary exhaust manifold. This secondary air supply passage also has a control valve for regulating the flow of the secondary air therethrough during the opening of the pressure operated valve.

    摘要: Cylinder head construction defining a hemispheric combustion chamber and including a guide wall facing an intake port to impart swirl to an incoming air-fuel mixture and permit use of a lean air-fuel mixture. The position of the guide wall relative to the cylinder center and relative disposition of the guide wall and a spark plug are made such that although the guide wall is effective in imparting swirl, a flame front may be efficiently propagated to all parts of the combustion chamber subsequent to ignition of the air-fuel mixture therein, whereby provision of the guide wall does not result in increased emission of hydrocarbon compounds in exhaust gas or formation of carbon deposits in the combustion chamber.
