Abstract: SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE     COMPOSED OF INSULATED GATE FIELD-EFFECT TRANSISTORS     Abstract of the Disclosure In a semiconductor integrated circuit device composed of insulated gate field-effect transistors, the improvement comprising the facts that the insulated gate field-effect transistors having gate insulating films of substantially equal thicknesses are arranged on a principal surface of a semiconductor substrate in the shape of a matrix, that gate input columns of the transistors are formed of polycrystal silicon layers, and that some of the transistors are made the enhancement type, while the others are made the depletion type.  Further, the respective transistors are formed by the self-alignment technique which employs the polycrystal silicon layers as a diffusion mask, and the depletion type transistors arc formed by implanting impurity ions opposite in the conductivity type to the substrate into selected areas of the surface of the substrate.  Thus, a read only memory in a MOS-IC chip has its occupying area reduced remarkably.

Abstract: A B S T R A C T       An engine system includes an internal combustion engine to which fuel is supplied by solenoid operated pump/ injectors.  Power is supplied to the injectors by a drive unit which is controlled by a control unit.  The engine includes a starter motor which is energised from a batt-ery by way of a time delay relay which comes into operation when a starter switch is actuated.  The control unit is arranged so that energisation of the starter when the switch is moved to the start position is delayed until the solenoids of all the pump/injectord have been energised to their maximum extent.  When the cranking of the engine reaches a predetermined value the injectors are allowed to operate at about half stroke, each injector being operated at least twice to provide the required amount of fuel for starting purposes.  Once the engine has started the system does not revert to normal operation until a sufficient period has lapsed for the terminal of the battery to rise to a value such that the pump/injectors are capable of supplying the required amount of fuel in a single stroke.

Abstract: Abstract of the Disclosure An improved thread convolution cooperates with a mating thread convolution to prevent reverse rotation between the thread convolutions in a direction tending to loosen a fastener.  In order to prevent reverse rotation between the two thread convolutions while enabling them to be rotated in a forward direction to tighten the fastener, the improved thread convolution has a resiliently deflectable spring portion which forms part of a flank of the thread convolution.  During relative rotation between the two thread convolutions in a direction tending to tighten the fastener, the spring portion is deflected from an extended position to a retracted position under the influence of a flank of the mating thread convolution.          This enables relative rotation to occur between the two thread convolutions without gouging or excessive scratching of the flank of either of the two thread convolutions.  Upon initiation of reverse rotation between the two thread convolutions, the spring portion moves outwardly and penetrates the flank of the mating thread convolution to prevent continued rotation in the reverse or loosening direction between the two thread convolutions.  The spring portion has a pointed end which is disposed radially outwardly of the pitch diameter of the thread convolution and radially inwardly of the crest of the thread convolution.
