Patent CA-2022377-C (CA)
Title: Videocassette storage and display sleeve
Inventor: ESSICK GALE W
IPC: G11B23/023
Filed: 1990-07-31
Granted: 2000-11-21
Abstract: A sleeve for storing and displaying a videocassette comprises a clear flexible plastic, elongated rectangular one-piece member, formed with an interior storage chamber completely enclosed except for an end opening through which a videocassette is inserted into and removed from the chamber. A chipboard cover having printed indicia thereon identifying a prerecorded program on the videocassette is retained within the chamber and slidably receives the videocassette therein. A pair of juxtaposed, elongated, preferably convex flanges, is formed on a spaced-apart pair of front and rear walls of the sleeve and extend partially across the end opening to retain the videocassette within the chipboard sleeve. Application of pressure by the thumb and finger of a user on spaced sidewalls of the sleeve adjacent to the end opening deforms the juxtaposed flanges to a parallel or concave configuration to enlarge the opening for removing the videocassette from the storage container for use, with the chipboard cover remaining in the storage chamber for subsequent removal at a later date in a nondeformed condition.

Title: Ground fault detector
Inventor: KINOSHITA KAZUMI
IPC: H04M3/30
Filed: 1990-01-12
Granted: 1994-11-22
Abstract: ABSTRACT    In a ground fault detector for long distance sub-scriber lines accommodated in a small capacity digital electronic exchange, a DC/DC converter for power supply is stopped during detection of ground fault.  Upon reception of the stop signal, the DC/DC converter con-verts the power supply voltage for the subscribers to a voltage as the system power supply of the exchange, namely to a low voltage before voltage conversion of the DC/DC converter.  The battery feed circuit can maintain the alarm condition, even if a current flows continuously to the battery feed resistor due to a ground fault, until the ground fault is re recovered by the maintenance person without breaking the resistor.

Abstract: In the audio signal reproducing apparatus, information on the transfer characteristics representative of the transfer characteristics from virtual sound sources to both ears of a listener in at least a first quadrant of the rotational angular position of the head M of the listener is stored in storing means 22. The transfer characteristics in rotational angular position of the head M represented by detection outputs from detecting means 5L, 5R and 13 for detecting the rotational angle position depending upon the movement of the head of the listener are formed based upon the transfer characteristics information of at least the first quadrant stored in the storing means and left and right channel audio signals are processed by audio signal processing means 23 for achieving a proper binaural reproduction relative to the virtual sound sources.      Also in the audio signal processing apparatus of the present invention, information on the transfer characteristics from virtual sound sources to both ears of a listener for each given rotational angle depending upon the movement of the head M of the listener is stored in storing means 62. The rotational angular position of the head of the listener is detected by detecting means 45L, 45R and 53 at a solution higher than that of the information of the transfer characteristics stored in said storing means. The information on at least two transfer characteristics in the vicinity of the rotational angular position represented by the detection outputs from detecting means is read from the storing means. The information on the transfer characteristics in the rotational angular position of the head represented by the detection output is interpolation operated by interpolation operating means 61. Based upon the information on the transfer characteristics determined by the interpolation operation means, left and right channel audio signals are processed by audio signal processing means 63 for achieving a proper binaural reproduction relative to the virtual sound sources.

Filed: 1992-04-15
Granted: 1997-10-14
Abstract: A phase compensation circuit for use with a resolver circuit that compensates for resolver angle measurement error without the use of special compensation windings on the resolver or the buffer amplifer associated with the compensation windings. With the  present invention, primary windings from a plurality of resolvers may be conructed in parallel and powered by one amplifier, which provides a major hardware reduction over conventional circuits. A digital computer is employed to process integrated data indicative of the phase shift of signals generated by the resolver, and compute error correction signals that compensate sine and cosine angle data output signals of the resolver. No resolver compensation windings are necessary and no additional electronic equipment is necessary. The present invention provides increased accuracy to fulfill more stringent angle measurement specifications.

Filed: 1992-12-24
Granted: 1996-05-07
Abstract: A slant plate type compressor having a capacity or displacement adjusting mechanism includes a housing for a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a slant plate having a surface with an adjustable incline angle.

The pressure in the suction chamber is controlled by a valve control mechanism which is disposed in a passageway linking the crankchamber and the suction chamber. An internally controlled safety valve device prevents an abnormal pressure differential between the crank and suction chambers. The internally controlled safety valve device is provided within the valve control mechanism, thereby obtaining an easily manufactured slant plate type compressor having a durable and reliable capacity adjusting mechanism with a safety valve device.

Title: Linearized output control of a nonlinear amplifier
Inventor: BRAATHEN RUSSELL E
IPC: H03G3/20
Filed: 1993-02-03
Granted: 2002-04-23
Abstract: An amplifier circuit for providing precise linear control over the output of a nonlinear amplifier, including a nonlinear gain controllable amplifier and an output control circuit. The output control circuit is connected to sample the signal output by the nonlinear amplifier. The amplifier output signal may be a continuous or a discontinuous signal. The output control circuit also receives a baseband signal. The sampled amplifier output signal and the baseband signal are alternatively transmitted to a detector. The detector produces a signal representative of the power level of either the sampled amplifier output signal or the baseband signal. The signals produced by the detector are stared separately in a pair of sample-and-hold circuits. A difference amplifier determines the difference between the stored signals and transmits this difference signal to the gain control input of the amplifier.   The output signal from the amplifier is thereby adjusted to linearly track the baseband signal.

Filed: 1993-12-03
Granted: 1997-09-30
Abstract: The vapour generator for chemical vapour deposition plants allows the extraction of metalorganic vapours from liquid or solid sources.  It mainly consists of a container into which a gas flows in, and as it passes near the reagent, it is saturated with the vapours produced and transports them to the reaction chamber.  Only the generator is brought to a temperature which is higher than room temperature so as to obtain a vapour which is saturated with a high quantity of reagent.  To avoid vapour condensation in the pipe system transporting it from the generator to the reaction chamber, it is diluted with a carrier gas directly in the body of the heated generator, reducing in this way the condensation temperature of vapour which becomes unsaturated.  For this purpose, the generator contains a dilution bypass-line in the upper base into which the carrier gas is made to flow. The pipe system going from the generator to the reaction chamber can be held at room temperature without any condensation risks.
