Patent TW-248628-B (TW)
IPC: H04N9/77
Filed: 1992-12-30
Granted: 1995-06-01
Abstract: A preprocessor for conditioning interlace-scan video signals for frame based compression, includes apparatus to accept fields of interlace-scanned video and provide fields of interlace-scanned luminance and chrominance component signals. The fields of interlace-scanned luminance component are combined into respective frames of luminance signal and applied to compressor apparatus for further processing. The fields of interlace scanned chrominance components are independently processed at the field level to generate lines of chrominance values which are interstitial to the lines of the original chrominance values and at a lesser pixel and line density. The independently processed fields of interlace-scanned chrominance signals are combined into respective frames of chrominance component signals and applied to compressor circuitry for further processing. Performing the chrominance signal interpolation and subsampling at the field level tends to eliminate a majority of color distortions around moving images. Receiver apparatus is configured to perform post decompression processing to generate frame data having the original pixel and line density.

Title: Commutator electric machine
Inventor: YANG TAY-HER
IPC: H02K21/00
Filed: 1994-05-31
Granted: 1996-04-21
Abstract: A commutator electric machine employs shifting of armature neutral axis to control flux excitation and it's speed. With specific angle between armature winding axis and magnetic field axis, this electric machine can achieve the performances as following : The electric angle between armature winding axis and magnetic field axis maintains at 90 degrees. The electric angle between carbon brush and magnetic field axis can be varied from 0 degree to 180 degrees by shifting the carbon brush. By varying this electric angle clockwisely from 90 degrees to 180 degrees, the armature will rotate clockwisely with different speed correspondingly. By varying this electric angle counterclockwisely from 0 degree to 90 degrees, the armature will rotate counterclockwisely with different speed correspondingly. The magnetic field is established by magnetic materials or materials with residual flux (i. e, carbon steal and etc.). The direction of this magnetic field is the same as the direction of the field excited by the armature winding. The direction of the field excited by the armature winding is controlled by shifting carbon brush as mentioned previously. Thus this electric machine can rotate in one direction. If the mechanical power is input from the shaft, this electric machine behaves like a generator and it's output performance is similar to series generator. The polar direction of the field excited by the armature winding and controlled by shifting carbon brush is the same as the polar direction of the magnetic field established by residual flux.

Title: Insulation displacement contact including retention means
Inventor: DRACH ROBERT G
IPC: H01R4/24
Filed: 1995-06-13
Granted: 1996-01-01
Abstract: An insulation displacement connecting (IDC) terminal that allows wires to be parked in a retaining region thereof prior to being terminated within and IDC portion of the terminal. The retaining region of the terminal is generally a rounded longitudinal slot having a width which is slightly less than the outermost diameter of a conductor to be inserted into the terminal. The terminal which is designed with large flat spring contacts located about a central slot, includes an IDC portion, which cuts into the insulation of the wire to establish contact. A slight gap in a top portion of the retaining region pulls apart and allows for insertion of a wire into the slot of the retaining region. The spring contacts of the terminal pull together and the gap is narrowed once the wire enters the retaining region, thus, preventing the wire from escaping through the gap. The spring contacts then close on the wire where it remains parked until such time as the wire is terminated within the IDC portion of the terminal. The retaining region allows conductors to be dressed into the terminals of a connector module as one operation and then seated into the IDC terminals as a second operation. The terminals are adapted for use with connector modules which house multiple pairs of IDC terminals on both the front and rear sides thereof. The connector modules are insertable into a hinged mounting bracket that is mounted at a telephone switching area to make up a modular connecting block.

Title: The driving circuit for traveling-wave type ultrasonic motor
Inventor: LIN FAA-JENG
IPC: H02N2/14
Filed: 1996-05-22
Granted: 1997-01-01
Abstract: A driving circuit, which is two-phase chopper inverter combination, is proposed to provide two-phase balance voltage for the traveling-wave type ultrasonic motor(USM). The two-phase chopper-inverter driving circuit is proposed in Fig 1. Each chopper-inverter driving circuit is composed of one boost chopper cascading with one half bridge series resonant capacitor-parallelload inverter. Thereby, the two-phase sinusoid output voltage, VA and VB with a phase difference of 90 degrees, can be maintained at the same constant peak values at the same switching frequency. The function of the chopper, which is implemented with MOSFET, is to regulate the inverter output voltage with PWM direct-dutycycle control. The resonant inverter using parasitic impedance of the USM to provide sinusoidal voltage source is also implemented with MOSFETs. The Lr1 and Lr2 inductance are inserted in series with the load for each inverter, respectively, in order to become resonant with the inherent parasitic capacitance, Cdl and Cd2, of the USM. The driving frequency of the inverters is the major control variable and the rotor rotating direction can be controlled by the phase difference between the two-phase outputvoltages of the inverter.
