Title: Digital high definition television video recorder with trick-play features
Inventor: NAIMPALLY SAIPRASAD V
IPC: H04N21/4147
Filed: 1994-02-18
Granted: 2002-08-06
Abstract: A signal processing system for a high resolution digital video tape recorder (VTR) includes circuitry which processes the high resolution video signal to produce a relatively low resolution video signal which may be recorded on the tape with the high resolution video signal. The low resolution video signal is encoded using intra-frame techniques and recorded in fixed-length segments which appear at predetermined locations in the tape tracks. Low resolution segments representing images in different frames may be recovered and combined to produce an image which is suitable for display in trick-play modes. During normal play modes, the data stream representing the high resolution image is recovered in sequence. Accordingly, this high resolution image may be encoded using predictive coding techniques as well as intra-frame techniques.

Title: Gas-containing product supporting structure
Inventor: DICKIE ROBERT G
IPC: B65D81/00
Filed: 1993-03-16
Granted: 1999-04-06
Abstract: A supporting structure (11) for positioning a product within an outer shipping container takes the form of a plastic air bladder shaped on one side to provide a cavity (13) having internal dimensions maching external dimensions of the product and shaped on the other to have external dimensions matching internal dimensions of the shipping container. The air bladder may be either a vertical or a horizontal positioning element and is typically used in pairs within a single container. The air bladder is compact and can be discarded after use with minimal environment impact. In examples shown, the air bladder is of a plastic material such as polyethylene and is produced by blow molding, making it particularly suitable for disposal after use by a recycling process, thereby further reducing potential environmental impact.

Title: High temperature heat exchanger
Inventor: CIZMAR LLOYD EDWARD
IPC: F28F19/02
Filed: 1994-05-10
Granted: 2005-03-08
Abstract: A high temperature heat exchanger having an improved support apparatus for suspending a tube bundle.      The improved support comprises a skirt from which the tube sheet and the bundle are supported, and a lip on an upper end of the skirt engaged in a flange assembly receiving the lip. A first refractory lining on an inside face of the skirt extends downwardly from the lip, and overlaps a second refractory lining on an outside surface of the skirt extending upwardly from adjacent the tube sheet toward the lip. By securing the support apparatus in the cold flange assembly, the interior refractory is not used for supporting the tube bundle and can maintain its integrity, have a lower incidence of premature failure and yield an optimum refractory life.

Patent CA-2153273-C (CA)
Inventor: HOANG CHINH L
IPC: H03L7/181
Filed: 1995-07-05
Granted: 1999-03-16
Abstract: An oscillator system and method in which a time period (inverse of frequency) of a multi-stage ring oscillator (ROSC) is adjusted by a bias current which controls the charging and discharging times of respective capacitors (e.g., interelectrode capacities) within each stage.  The time periods of the unadjusted oscillator are counted along with the time periods of a reference clock over a same period of time and a count difference between the two counts is determined.  The count difference is applied by a logic circuit in accordance with an algorithm relating count differences to incremental bias current levels to adjust the frequency of the oscillator.  The logic circuit generates digital gate signals corresponding to the count difference and these signals automatically select the bias current level needed to bring the oscillator frequency into close agreement with the reference clock frequency.  The digital gate signals are stored in a non-volatile memory so that the oscillator will continue to operate at the adjusted frequency (i.e., that of the reference clock) even if the reference clock is no longer present and power is temporarily removed.  The oscillator system is well suited for implementation by complementary metal oxide semiconductor (CMOS) technology as part of an integrated circuit (IC).

Title: Semiconductor differential pressure measuring device
Inventor: IKEDA KYOICHI
IPC: G01L19/04
Filed: 1996-04-10
Granted: 2000-09-05
Abstract: This is a semiconductor differential pressure measuring device comprising two measurement diaphragms and two detection sensors provided in a semiconductor substrate using micromachining techniques, and a computing circuit which computes the differences between these two sensor outputs: for each of the two measurement diaphragms, the measuring pressure transmission communicating hole being provided respectively so that these two measurement diaphragms operate in opposite phases by the differential pressure; and the above two sensors being provided on each relevant measurement diaphragm and detecting the displacement or strain of each measurement diaphragm generated by the differential pressure applied to each measurement diaphragm. Detecting the differences in the displacement or strain of each of these two measurement diaphragms cancels the static pressure error and temperature error and, thus, offers a semiconductor differential pressure measuring device which is excellent in temperature and static pressure characteristics. Further, the computing circuit can be configured simply by composing a required bridge circuit using at least one first sensor and one second sensor, each located on each of the two measurement diaphragms, leading to a reduction in manufacturing costs.
