Abstract: A unit drive assembly (2) is used with postage meters (4) of the type which include a stationary base (6) and moveable print head (8). The base (6) and print head (8) are mechanically connected so that input information to the base (6) is mechanically transmitted to the print head (8). The assembly (2) includes one or more drive tracks (10) along which a series of balls (16) are positioned. A first portion (12) of the drive track (10) is carried by the base (6) while a second portion (14) is carried by the head (8). The first (12) and second (14) portions are aligned when the head (8) is in the home position; it is at this time a ball drive (28) carried by the base (6), moves the balls (16) along the track (10) discrete distances equal to one or more ball (16) diameters. The head (8) includes one or more print wheels (36) driven by the balls (16) positioned along the second portion (14) of the track (10) so that the distances the print wheels (36) rotate, which determines the value to be printed, depend upon the distances the balls (16) are driven along the tracks (10).

Abstract: An eddy current type brake system comprises a rotor (4) mounted on an shaft connected to an engine, a permanent magnet (6) movable relative to the rotor (4) and a casing (9) provided between the rotor (4) and the permanent magnet (6) for sealingly housing the permanent magnet (6). The permanent magnet (6) applies a brake force to the rotor (4) when the permanent magnet (6) approaches the rotor (4) since an eddy current flows in the rotor (4) upon approaching whereas the brake force is not applied to the rotor (4) as the permanent magnet (6) leaves the rotor (4) since the eddy current no longer flows in the rotor (4) upon leaving. The permanent magnet (6) is sealedly housed in the casing (9) Therefore, moisture and dusts do not deteriorate the characteristics of the magnet (6). In addition, heat produced upon approaching of the magnet (6) to the rotor (4) is absorbed by the casing (9) located between the rotor (4) and the magnet (6).

IPC: G03F7/36

Abstract: It has been found that an ultrasonic bath treatment is particularly suitable for removing layers from a substrate in specified areas. Relatively high ultrasonic intensity can be used if a layer has to be removed only along an edge of a substrate. Then only said edge of the substrate is immersed in the bath liquid, the substrate being held in a damped manner just above the point of immersion. If, on the other hand, layers are removed in accordance with patterns extending from the edge to the interior of a substrate face, relatively low ultrasonic intensity has to be used. In order to achieve this, commercial ultrasonic baths were lined with rubber mats. If layers are to be removed in areas not masked with photoresist strips, it is advantageous to use an etching liquid with as high a viscosity as possible. Phosphoric acid, in particular, is suitable for increasing the viscosity. To increase the etching rate of ITO it is advantageous to add a complexing agent for indium and tin to the etching liquid. Chloride ions, in particular, are suitable for this purpose. The methods can be applied, in particular, to layers on liquid-crystal cell substrates and to copper layers on printed circuit boards.

Abstract: A comparator circuit for operation at video rate signals includes input switches (22,12) to alternately couple a reference (V RX ) and a signal (V IN ) potential to a summing capacitor (24). The capacitor (24) is coupled to the input (gate P13) of a first inverting amplifier (A1). The amplifier includes a switch (26) between input and output (gate N33) terminals for selectively autozeroing the amplifier. The amplifier is direct coupled to the input (gate N33) of a second inverting amplifier (A2) having an autozero circuit (28) exclusive of a connection to the input of the second amplifier. Timing circuitry for controlling the autozero function is arranged to minimize the effects of clocking transients upsetting the autozeroed potentials thereby reducing the response time and enhancing the sensitivity of the comparator.

Abstract: There are provided a method of inspecting and evaluating semiconductor substrates, good quality semiconductor substrates, a method of manufacturing good quality semiconductor substrates, and a method of manufacturing semiconductor devices using good quality semiconductor substrates. 
     A semiconductor substrate (1) is processed with aqueous basic solution. In this process, the substrate (1) is dipped in the aqueous solution or exposed to a vapor of the aqueous solution. With this process, the surface of the substrate (1) is selectively etched. The substrate surface after the etching process is radiated with a laser beam to measure a light scattered point density. The quality of the substrate (1) can be judged in accordance with the measured density. A thermal treatment may be carried out before or after processing the substrate with the aqueous basic solution. The thermal treatment considerably changes the fine defect density on the surface of the substrate (1). In accordance with such a change, the quality of the substrate (1) may be judged. If a substrate (1) judged as having a good quality is used, a semiconductor device having a good quality substrate can be obtained.

Abstract: Unwanted substances such as gums and phosphatides also get into the oil in the production of crude vegetable oils. Many of these substances can be hydrated and can be removed by aqueous degumming, that is to say by a treatment with water or steam, swelling or hydration with subsequent separation, normally by centrifugation. The removal of the remaining non-hydratable substances requires special and very elaborate methods. Reducing the content of gums which can no longer be hydrated with water and simultaneously reducing the wax content of vegetable oils is considerably simplified and improved by the following treatment steps which are to be carried out consecutively. …<??>First a dilute acid or an anhydride is mixed carefully with the oil at elevated temperature and the mixture is stirred for a contact time lasting several minutes. Then a dilute basic solution is added and this mixture is likewise stirred slowly for a reaction time lasting, for example, two hours. This is followed by very rapid heating, and the substances which have separated out, and the water are separated from the oil and, if required, the oil is washed with water.
