Patent EP-0190911-A2 (EP)
Inventor: NICHOLSON WARREN HENRY
IPC: H04N9/64
Filed: 1986-02-03
Abstract: 57 The signal processor (Fig 1) includes a field or frame store (24). If a video signal having a non-standard relationship between its line frequency (f H ) and its color subcarrier frequency (f sc ) is processed, corresponding signal samples from an analog-to-digital converter (12) of successive fields or frames are misaligned in the store, leading to a degradation of the processed signal. A nonstandard signal detector (22, 19, 23, 21) produces a control signal indicative of the existence of the non-standard relationship and the mode of operation of the processor is controlled accordingly. in one example, field or frame processing and line processing are selectively performed depending on the control signal, line processing being perfomed in the presence of the non-standard signal.

Abstract: In an image processing apparatus, an image signal generator includes a ROM (16) and a D/A converter (2). The ROM consists of gain conversion tables. A PWM signal generator includes a frequency divider (6), a flip-flop (8), an integrator (10, 11), a voltage divider (13), and a comparator (4). The frequency divider is synchronized with the ROM in response to a sync selection signal. An output from the frequency divider is further frequency-divided by the flip-flop and then converted into a triangular wave signal by the integrator. The bias component of the triangular wave signal is adjusted by the voltage divider. The resultant signal (SAW) supplied to one input terminal of the comparator is compared thereby with an output from the D/A converter, thereby obtaining a PWM signal. The peak and bottom values of the triangular wave signal are always matched with the maximum and minimum values of the output from the D/A converter.

Abstract: An apparatus capable of simultaneously coating one side of each of several surface type fastener tapes (F) or the like traveling longitudinally in coplanar, parallel spaced relation to one another. For simultaneously coating two fastener tapes (F) a pair of end coating units (34) and one intermediate coating unit (34ʹ) are arranged alternately with the fastener tapes (F). Each fastener tape (F) travels with its opposite longitudinal edge portions slidably engaged in recessed guideways (52, 52ʹ) defined in the end and intermediate coating units (34, 34ʹ). A coating material (C) is supplied through passageways (42, 42ʹ) in the coating units (34, 34ʹ) onto the surfaces of the fastener tapes (F) traveling therethrough. Mounted to the coating units (34, 34ʹ) so as to extend across the fastener tapes (F), a doctor blade (36) has its scraping edge (66) held against the surfaces of the tapes (F). The fastener tape guideways (52, 52ʹ) in the coating units (34, 34ʹ) all decline from their upstream toward downstream ends with respect to the traveling direction of the tapes (F), so that the coating material (C) collects in spaces bounded by the tapes (F), coating   units (34, 34ʹ) and doctor blade (36). The doctor blade (36) creates a coating (Cʹ) of constant thickness on each fastener tape (F) as the latter travels therepast.

Abstract: A rectifier is fabricated from a P-N junction having a P-type semiconductor layer and an adjacent N-type semi­conductor layer. A mesa structure is formed in at least one of said layers. Impurities are deposited at the top of the mesa to form a high concentration region in the surface thereof. The impurities are diffused from the top surface of the mesa toward the P-N junction, whereby the mesa geometry causes the diffusion to take on a generally concave shape as it penetrates into the mesa. The distance between the perimeter of the high concentration region and the wafer substrate is therefore greater than the distance between the central portion of said region and the wafer substrate, providing improved breakdown voltage characteristics and a lower surface field. Breakdown voltage can be measured during device fabrication and precisely controlled by additional diffusions to drive the high concentration region to the required depth.

Abstract: A ferrofluid seal is disclosed for use in a bearing application with a stationary shaft (2) about which a hub (4) rotates. The seal consists of a permanent magnet (30) and one or more annular pole pieces (32) which form a magnetic circuit with the bearing shaft (2). The magnetic circuit includes an annular gap (3) between the shaft (2) and the pole pieces (32) in which the magnetic flux traps a magnetic fluid (38) which bridges the gap (3) to form a seal. The shaft (2) is tapered in the gap (3) area to form a wedge-shaped gap which accommodates changes in the magnetic fluid volume due to temperature variations while holding the fluid (38) within the magnetic field to maintain the seal. The pole piece (32) which forms the gap (3) has a straight annular face located at a constant radial distance from the shaft axis. At high operating temperatures, expansion of the magnetic fluid (38) causes the fluid to fill the taper on the shaft (2), but, since the shaft (2) is stationary, fluid splash is eliminated. The straight surface of the pole piece (32) controls fluid splash caused by centrifugal force.

Abstract: A laser interferometer-refractometer for measuring the refractive index of a gas has a laser (1), at least one beam splitter (10) for splitting up the laser light beam into at least one pair of component beams (20, 20'), an evacuable cell (25) which forms the vacuum travel path of a total travel path, formed from a travel path in the vacuum and a travel path in the gas to be measured, of a component beam (20) of the pair of component beams, and at least two beam deflectors (8, 9), which unify the component beams (20, 20') and are intended to generate interferences between the component beams. The optical path length of one component beam (20) can be adjusted for the purpose of enhancing the measurement accuracy. One wall (5), which is situated in the travel path of the component beam (20) and delimits the vacuum space of the cell (25), is constructed displaceably in order to adjust the optical path length. The measurable adjustability of the wall (5) produces different proportions of the travel path in the vacuum and in the gas to be measured, as a result of which the optical path length can be varied. The movement of the wall (5) produces interferences between the reflecting, unified component beams (20, 20') which can be measured by photodetectors (15, 14). <IMAGE>
