Title: Driver circuit for long luminescence life display device and method of driving such device
Inventor: KOMODA MOTOYOSHI
IPC: H05B44/00
Filed: 1992-09-24
Granted: 1996-12-10
Abstract: A driver circuit for a display device, in which first and second clock pulse generator circuits generate first and second clock pulses to a gate circuit for allowing the first clock pulse to pass when the first and second clock pulses are a high level, and by the output of the gate circuit, a combination of a transistor and an inductance generate a high voltage pulse.  The high voltage pulse is rectified in a triple voltage rectifying circuit to output a high voltage output for driving the display device such as EL elements, and the high voltage output can be reset by a low frequency pulse output from a discharge circuit.   As  a result, no inverter is required,  and a small-sized and light-weighted driver circuit is achieved with a long luminescence life of the EL elements and without noises offensive to the ear.

Title: Beam current limiting arrangement for a televison system with picture-in-picture provisions
Inventor: LAGONI WILLIAM ADAMSON
IPC: H04N5/45
Filed: 1992-11-19
Granted: 1999-10-12
Abstract: In a color television system having picture-in-picture (PIP) capability, apparatus is provided for automatically modifying the operation of a beam current limiting (BCL) section while the small picture is being displayed to prevent the visibility of the small picture from being adversely affected. In an embodiment, a contrast BCL control signal is decoupled from the contrast section, and a substitute control signal, at least approximating the user responsive contrast control signal, is substituted for it in response to a switching signal which causes the small picture to be inserted within the big gicture. however, the BCL section continues to be responsive to the beam current during the time interval in which the small picture is displayed so that the BCL contrast control signal accurately represents the contents of the entire image. In addition, the operation of an automatic contrast reduction section which is responsive to a peak-white representative video signal is also disabled during the time interval in which the small picture is displayed. In an alternate embodiment only the operation of the contrast BCL section is disabled, but the operation of the automatic contrast control is maintained. If desired, a brightness BCL control signal may also be decoupled from the brightness section.

Abstract: Pumping light from an optical pumping source is incident on an Er-doped fiber through a multiplexer to pump Er. When signal light is incident on the Er-doped fiber through the multiplexes in this state, the signal light is amplified by stimulated emission of pumped Er.      This amplified signal light is attenuated by a high-loss optical fiber and is output externally through a splitter and the like. Meanwhile, part of the amplified signal light is fed back to a driving source of the optical pumping source through the splitter so as to be used to adjust the gain of the optical fiber amplifier. With this operation, the output signal power is kept constant. In this case, since the high-loss optical fiber is connected to the output terminal of the Er-doped fiber, the noise figure of the optical f fiber amplifier can be kept small over a wide range of input light intensities.

Granted: 1999-03-02
Abstract: The present invention is directed to a novel converter for interposition between an AC power source and a DC load capable of maintaining a substantially unity power factor independent of the impedance of the load.          According to the invention, the converter has rectifying circuit means to provide DC power to a DC power output circuit from an AC source, means for varying the impedance seen by the AC source in the DC output circuit, and means responsive to a shift in AC input current away from an in-phase relation with the voltage of the AC source under loading of the DC power output circuit for controlling said impedance varying means in a direction to return the AC current towards in-phase relation with the AC voltage.          More particularly, according to the preferred form of the invention, the means for varying the impedance seen by the AC source in the DC output circuit includes a resonant circuit interposed between the rectifying circuit means and the DC output circuit and connected to deliver DC power thereto.  The converter includes a control circuit responsive to the DC voltage of the DC output circuit and the phase between the AC voltage and AC current.  The control converter also includes a variable impedance responsive to the resonant circuit current for controlling the phase angle between the resonant circuit current and voltage across the resonant circuit.

The stator (36) is mounted to the end of the axle spindle (10) by a securing bolt (52) so that the stator (36) can be easily removed for service without disturbing the axle bearings (14). As a part of the stator (36) assembly, a locating plate (46) is provided which allows the operating gap between the teeth (32) formed in the flange (19) and the teeth (37) formed in the stator (36) to be easily established upon assembly of the hub cap (22) to the wheel hub (18) by allowing the rotor (30) to contact the locating plate (46) when the hub cap securing bolts (24) have been loosened and the axle is supported. The flange (19) pilots on the inner annular surface in the wheel hub (18) thereby reducing the cost of assembly and improving overall functionality.
