Title: Apparatus for measuring an AC electrical parameter of a device
Inventor: TANAKA HIDESHI
IPC: G01R27/02
Filed: 1989-02-22
Abstract: In apparatus for measuring the AC electrical parameters of a Device-Under-Test (DUT), 205, such as a resistor, a capacitor or an inductor, at the desired frequency of a signal while applying a DC bias 208 to the DUT 205, an inductor 211 having a high impedance even in the low-frequency range and a low DC resistance is artificially formed by an electronic circuit (Fig. 3(a). By using the thus formed artificial inductor 211, measurement error due to low impedance of the inductor 211 in the low-frequency range and measurement error due to the DC offset caused by a high DC resistance are prevented. The input equivalent noise of an amplifier 203 is also prevented from being amplified by the amplifier 203. Thus, the high precision measurement of the AC electrical parameters of the DUT can be obtained. High DC bias voltage can be applied to the DUT 205 due to the DC blocking operations of a capacitor 212. <IMAGE>

Title: A controller for an electrical load.
Inventor: ADAMS DEREK STANLEY
IPC: H02P7/29
Filed: 1990-04-06
Abstract: A controller for an electric motor comprises a voltage controlled oscillator circuit (10) the output of which is transformed into a triangular waveform by a waveform generator (12). The output of the generator is applied to one input of a comparator (14). The other input is supplied with an error signal (e) signifying the difference between demanded output and actual output. To lessen the acoustic noise from the controller the period and amplitude of the output of the oscillator, and hence the waveform generator, are varied by a pseudo-random sequence generator (18) which is connected to the oscillator. The output of the comparator is a variable mark/space ratio rectangular wave.

Title: Continuous-motion line-array telecine
Inventor: BALDWIN JOHN LEWIS EDWIN
IPC: H04N9/093
Filed: 1990-04-19
Abstract: A continuous-motion line-array telecine images the film image A onto three linear array sensors 61, 62, 63 having respective colour filters (71, 72, 73). Vertical scanning is provided by the continuous motion of the film. The sensors can be spaced by an amount equivalent to a given number of line scans for one film and television format combination. To accommodate other formats, a cylindrical lens pair (44, 46) is selectively included, which provides a desired magnification in the vertical direction according to the required television format. Magnification is not varied in the horizontal direction. The sensor spacing does not then need to be changed and the sensors can be made as an integral device 65, so that they can be constructed closer together and are likely to have more similar characteristics. <IMAGE>

Title: Disc brake.
Inventor: PANTALE DAVID
IPC: F16D65/02
Filed: 1990-12-04
Abstract: A disc brake comprises a caliper housing 10 having a body member 12 and an arm member 14 connected to one another by a bridge 16. A leading side of the arm member 14, that is the side which the rotor of a disc brake reaches first during normal rotation thereof, is more rigid than a trailing side thereof. A set of stiffening fibres 28, 30 is provided in each of first and second bridge portions 22, 24 of the bridge 16 to produce the difference in rigidities between the leading and trailing sides of the caliper housing 10, wherein the first bridge portion 22 comprises a greater density of fibres 28 than the second bridge portion 24. This difference in rigidities reduces uneven wear of the brake pad and, as a consequence, reduces brake squeal and noise. <IMAGE>   <IMAGE>
