Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a control circuit for a power converter apparatus using self-extinction devices as switching devices, in which turn on and turn off opera-tions of the self-extinction devices are controlled by gate pulses which have been subject to pulse width modulation with a pulse train having a pulse width which is sinusoidally varied, and, at the same time, the self-extinction devices in same phase are made conductive in a predetermined period corresponding to an output voltage reference value to make an output of the power converter apparatus be in a shorted state in the sense of DC current to thereby control the output of the power converter apparatus.

Abstract: Abstract A rockbolt  for  installation  in a bore  in the roof of an underground excavation, such as a tun-nel or mine, to support the roof, comprises a sleeve having a closed  top and ports  in its upper end, a plunger slideably mounted in the sleeve, and harden-able binder material encapsulated in burstable cart-ridges in the sleeve above the plunger.  The rockbolt is inserted into the bore and the plunger is operated either mechanically or by the application of pressur-ized  fluid  to  the  plunger,  to  extrude  the binder material to secure the rockbolt in the bore.  A mech-anical  anchor  can  be  provided  on  the  top  of  the sleeve so the rockbolt can be tensioned before the binder  sets.   Alternatively,  faster  setting  binder can be provided in -the sleeve below the balance of the binder so that it is the last to be extruded and remains near the top to secure the top to the sur-rounding rock before the balance of the binder sets so that the rockbolt can be tensioned before the bal-ance of the binder sets.

Abstract: A planar inertial sensor includes a sheet member having one inner planar element adapted for limited angular motion about a (Y) axis perpendicular to an input (Z) axis. In a gyroscope form, the inner planar element is also adpated for limited angular motion about an (X) axis normal to and intersecting with the Y axis. The gyroscope form includes an outer driving planar element which is continuously driven in an oscillatory manner in limited excursions about the Y axis. The driving element is coupled to the inner element so that oscillatory motion of the driving element is coupled to the inner element. Position sensors provide signals representative of the angular position of the inner element relative to the X axis, which in turn are representative of angular rates impressed on the sensor about the input (Z) axis which is orthogonal to the X and Y axes. In an accelerometer form, the inner planar element is characterized by a mass imbalanace across the Y axis. Positon sensors provide signals representative of the angular position of the inner element, which in turn are representative of the acceleration of the sensor in the direction of the input (Z) axis.

Abstract: ABSTRACT OF THE DISCLOSURE         A children's automobile-mounted safety seat has a body support with a seat portion, a base for rotatably supporting the seat portion, and reclining adjustment members for adjusting the angle of inclination of the body support portion.  A journal shaft connecting the seat portion to the base is positioned in the rear lower region of the seat portion in a cavity or hollow space in the base.  Reclining adjustment elements are also positioned below the front lower region of the seat portion in the cavity so that manipulation of the reclining adjustment elements is possible only by reaching through an opening in the base into the cavity.  A child sitting on the seat normally cannot reach into the cavity and is thus protected against injury by said reclining adjustment elements.

Abstract: SEMICONDUCTOR INTEGRATED CIRCUITS GETTERED WITH PHOSPHORUS            Abstract For achieving dense packing of MOS transistors at the top surface of a silicon semiconductor body, second level metallization including arsenic doped polysilicon contacts are used in conjunction with a phosphorus gettering step at a time when the top surface is sealed against the introduction of phosphorus by an undoped sacrificial glass layer, i.e., which is essentially free of phosphorus.  The second level metallization is thereafter completed by coating the polysilicon with a high conductivity metal, such as aluminum.  During the gettering, the polysilicon contacts are insulated from the first level metallization by a planarized glass layer doped with phosphorus to a concentration below the saturation level of phosphorus in the glass.

Abstract: Abstract of the Disclosure The phase of a reproduction reference signal RS output from a decoder, which decodes the count value of the counter, is compared with that of an arriving hori-zontal synchronizing signal TH by a phase comparator.          Based on this comparison result, a phase discriminating circuit discriminates whether the phase of the repro-duction reference signal RS is advanced, delayed or in-phase with the arriving horizontal synchronizing signal TH.  Based on this phase discrimination result, the dividing ratio setting circuit sets the dividing ratio of the counter such that the reproduction reference signal TH is pulled in with the arriving horizontal synchronizing signal TH.

Abstract: ABSTRACT OF THE DISCLOSURE           A spray shield and system for controlling the spray generated by the wheels of automotive vehicles when traveling on a roadway surface.  The shield is adapted to be disposed above the roadway surface vertically depending from the vehicle and spaced rearwardly from a vehicle wheel in a plane extending transversely to the vehicle.  The shield is in sheet form and has front and rear surfaces and top and side borders.  A plurality of downwardly depending, contiguous flaps extend, when the shield is in position on the vehicle, horizontally between the side borders, the flaps to permit flow of air and spray through the shield and cause downward deflection thereof.  A pair of air deflection surfaces, to be vertically oriented during operation, one extending outwardly along each of the side borders and each angled with respect to the front surface of the spray shield are provided to deflect air and spray laterally, from one side of the shield to the other.  The shield according to the present invention significantly reduces the hazard created by spray generated by a vehicle's tires by deflecting the spray downwardly and in a particular lateral direction, for example to the shoulder side of the vehicle.

Abstract: Abstract A pix-in-pix television display includes circuitry for reducing the amount of memory needed to hold one field of the reduced size image.  In the display apparatus, digital samples representing the large and small picture signals are developed at substantially equal rates by separate circuitry.  Subsampling circuitry stores one out of every five of the samples representing a horizontal line of the small picture.  These samples are displayed, synchronous with the large picture at a rate three-fifths times the display rate of the large picture samples to produce an apparent size reduction of one-third in the horizontal direction.

Abstract: ANALOG CIRCUIT IMPROVEMENT IN A DIGITAL      INTEGRATED CIRCUIT TECHNOLOGY     Abstract of the Disclosure A CMOS integrated filter for analog signals, usually includes a passive network of resistive and capacitive paired elements and a first differential amplifier, for implementing a second order filter function.  In such a filter, attenuation of higher frequencies an octave or so above the passband may not be sufficient for the filter to be useful.  An operational improvement is achieved by including d second amplifier in the integrated circuit structure for buffering the output of the filter.  Buffering is achieved in the second amplifier by voltage following an input of the first amplifier.  The improvement reduces capacitive coupling at higher frequencies and thus increases attenuation introduced by the filter at these frequencies.     - i -
