Title: Device for receiving closed captioned broadcasts
Inventor: HARIGAI MASAMI
IPC: H04N7/03
Filed: 1992-09-25
Abstract: ABSTRACT OF THE DISCLOSURE      A synchronizing/separator circuit separates a horizontal synchronizing signal and a vertical synchronizing signal contained within a television signal. A phase locked loop synthesizes a clock signal as 32 fH by phase locking the horizontal synchronizing signal with a divided version of the 32 fH clock signal. The phase locked loop includes a voltage controlled oscillator (VCO) responsive to the phase comparison go perform the phase lock. A circuit separates the run-in clock and caption data in horizontal scanning period 21 H in the vertical blanking interval. A phase comparator receives the run-in clock and phase compares is with the 32 fH clock to produce an alternating control signal which is applied directly to the voltage controlled oscillator for rapid phase locking of the voltage controlled oscillator in preparation for decoding the caption data. The voltage controlled oscillator is controlled by the charging and discharging rate of a capacitor charged by a constant current source. The control signal varies the charging and discharging rate of the capacitor to effect rapid phase lock to the run in clock.

Filed: 1992-09-30
Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a process for continuously and efficiently producing a styrenic polymer having a high degree of syndiotactic configuration which comprises effecting polymerization reaction by continuously introducing a styrenic monomer and a polymerization catalyst into a polymerization reactor, the inside of which has been brought into fluidized state by particles previously fed therein, which process is characterized in that the polymerization reactor temperature is controlled by vaporizing a part of the styrenic monomer which has been introduced into the polymerization reactor, while the inside of the reactor is maintained under reduced pressure.  According to the above process, such problems as difficulty in polymerization reactor scale-up, adhesion of polymer to the reactor inside and polymer particle agglomerate are simultaneously solved, and thereby the industrial significance of the process is remarkably enhanced.

Title: Endoscopic surgical instruments having rotatable end effectors
Inventor: BALES THOMAS O
IPC: A61B10/06
Filed: 1993-02-05
Abstract: ABSTRACT OF THE DISCLOSURE      Medical instruments are provided having end effectors and end effector actuator apparatus which are rotatable relative to the end effectors.  The instruments generally include a tube which is typically coupled to the end effectors via a clevis around which the end effectors pivot, a push rod extending through the tube and coupled to the end effectors, an actuator apparatus engaging the tube and the push rod and imparting reciprocal axial motion to the push rod relative to the tube, and the end effectors.  The actuator apparatus includes a sleeve, spring, handle, and lever arm.  The sleeve is movable along the longitudinal axis of the tube against a biasing force of the spring, but is restrained from rotating about the tube.  The sleeve has a locking element on its proximal end.  The handle surrounds and rotatably engages the proximal end of the tube and has a locking element on its distal end which mates with the locking element of the sleeve and disengages therewith when the sleeve is advanced along the tube.  Upon disengagement, the tube, push rod, and end effectors can be rotated.  The lever arm pivotally engages the handle and is coupled to the push rod such that pivotal movement of the lever arm relative to the handle effects movement of the push rod relative to the tube and pivotal movement of the end effectors.  To decouple rotation of the push rod from the lever arm, a generally spherical push rod engaging element is provided in a generally cylindrical bore of the lever arm.

Abstract: ABSTRACT     In a vertical sawtooth generator of a vertical deflection circuit, a first comparator generates an output signal when a retrace portion of a sawtooth signal is at a first magnitude to initiate a vertical trace portion of the sawtooth signal. An amplifier responsive to the sawtooth signal generates a feedback current at a time that occurs more than one-half of the length of vertical trace portion after vertical trace is initiated. The feedback current is coupled to a capacitor to develop a capacitor voltage. The capacitor voltage is applied via a voltage-to-current converter to an integrating capacitor to develop in the integrating capacitor the trace portion of the sawtooth signal.

Filed: 1994-03-15
Abstract: A portion of film, with a length proportionate to the dimensions and to the characteristics of the product to be wrapped, is subjected to a transverse pre-stretch-ing, the extent of which is also proportionate to the said parameters. The film is held at one end by a fixed dispenser (30) and at the other end by a movable rear clamp (61), which conveniently reduce the longitudinal tension of the film, both in pre-stretching and during the subsequent lifting of the product. In this phase, the side clamps (78-178) approach each other to reduce the pre-stretching, and are then inserted under the product and are opened, to extend the side flaps of the film under the product. This is followed by the operation, as a group, of the rear folder (52), which extends under the product a portion of the film held by the associated rear clamp (61), and the pusher (55) which pushes the product on to the front folder (37), while a final flap of film is drawn from the fixed dispenser (30), ie extended over the whole length of the bottom of the product, is cut to size, and is disposed under the side flaps and the rear flap, which has been released at the correct time by the said rear clamp.
