摘要:
In order to achieve a drive system having a simple structure in which a cartridge having therein a wound magnetic tape can be supplied or replaced in small installation space, a carrier unit structure is employed in which a cartridge is horizontally retracted from a magazine capable of horizontally inserting/removing the cartridge and then held therein. Further, a drive unit is located beneath the carrier unit, and the cartridge held in the carrier unit is released so that the cartridge can be dropped and loaded into the drive unit.

This invention prevents deterioration in characteristics of a semiconductor device having a lead frame that is thin and uniform in thickness. More specifically, this invention relieves resin distortion caused by a difference in thermal expansion coefficients between the lead frame and the sealing resin in order to prevent the characteristic deterioration caused by some factors such as moisture invasion from outside and mechanical pressure. A lead frame for a resin-sealed semiconductor device of this invention is composed of an element-mount part, a horizontal part for fixing the lead frame for resin sealing, and a central lead having side leads formed in parallel on both sides thereof. The element-mount part, the horizontal part and the central lead are formed integrally. In the lead frame, at least one pair of resin-anchoring parts are formed on two opposing sides on the periphery of the element-mount part.

An IC socket includes a socket board having a plurality of contacts, and an IC platform vertically movably disposed on the socket board and adapted to support thereon an IC having a plurality of leads projecting sidewards from a body thereof so as to be contacted with the contacts. Inclined wall surfaces are formed at both ends of a row of the contacts and are adapted to guide the leads onto vertical wall surfaces formed at lower ends of the inclined wall surfaces. To this end, the contacts at the ends of the row are guided onto the vertical wall surfaces by the inclined wall surfaces when the IC platform with the IC body supported thereon is lowered, so that the leads are brought into contact with the contacts. The IC socket further includes a plurality of projections formed on an upper surface of the IC platform and adapted to support a lower surface of the IC body such that the lower surface of the IC body floats above the upper surface of the IC platform, such that the leads are not supported on a marginal wall projecting upwardly from a marginal portion of the IC platform, and such that a ventilation space or gap is formed between the lower surface of the IC body and the upper surface of the IC platform.

A predetermined control on an engine, i.e., a fuel-cut operation, is executed after an accelerator has been released under predetermined conditions when vehicle speed is higher than a fuel-cut vehicle speed value and engine speed is higher than or equal to a fuel-cut engine speed value. In an automatic transmission drivingly connected to the engine via a torque converter, a gear shift is initiated after the accelerator has been released. During a shift of the same kind, there occurs a variability in shift shock between the cases with and without the execution of the fuel-cut operation. In order to reduce this variability, the execution of the fuel-cut operation is inhibited until completion of the shift after the accelerator has been released under the predetermined conditions.

A running state control system for a motor vehicle comprises engine output torque control means, shift detecting means, and a valve timing control system (VTC). When detecting a shifting, the shift detecting means outputs a torque cutoff command signal to the engine output torque control means so as to actuate the valve timing control system. An opening timing of intake valves is changed thereby in a direction such to decrease an engine output torque. In another aspect of the invention control is exercised over a braking torque applied to the driving wheels of the vehicle in correspondence with a traction loss or skid detected thereat.

Supercharge pressure is vented from the induction manifold in response to a shift command for a shift which requires engine torque reduction for shift shock attenuation. The ignition is subsequently retarded during the inertia phase of the shift. The supercharge pressure reduces the amount of torque being produced by the engine prior a further reduction by ignition retardation. At the end of the inertia phase the ignition retard and pressure relief are stopped.
摘要:
A unified control device for engine and automatic transmission of an automotive vehicles serves to alleviate a racing select shock which occurs upon engagement of a driving clutch in the transmission when selecting a running range of the transmission to start the vehicle with an accelerator pedal depressed. The control device achieves a reduction control during changeover of the transmission into a running range from a racing state, to reduce at least one parameter representing the output power to be transmitted from the engine to driving wheels via the transmission, such as engine speed, engine output and/or transfer torque capacity of the clutch, etc. The reduction control is stopped as soon as the completion of engagement of the driving clutch has been detected, to allow the vehicle to be started without engine stalling.
