Inventor: MULDER ARJEN J
IPC: G07D5/00
Filed: 1996-07-09
Abstract: A method of setting the coin checking criteria in a coin operated machine wherein a coin is determined to be acceptable if a measurement derived therefrom falls within a prescribed acceptability range, comprises setting a narrow acceptability range for "good" coins and outside that a wider acceptability range for "still good" coins, determining a desired frequency of coins whose derived measurements fall within the two ranges, counting the number of coins whose measurements fall within the two ranges, and, if the frequency of measurements within the "still good" range exceeds the desired frequency, reducing the width of said range. The width of the range may be restored, possibly in a stepwise manner, when certain pre-set conditions, eg passage of a predetermined time, are met.

Patent DE-19643903-A1 (DE)
Title: Bipolar transistor with heterojunction manufacturing method
Inventor: RYUM BYUNG-RYUL
IPC: H01L29/08
Filed: 1996-10-30
Abstract: The method initially involves forming a buried collector (2), collector thin film (3), and collector sink on a semiconductor substrate. On the collector structure are formed a silicon oxide film (8), a polysilicon film (9) for a base electrode, a nitride film, and an oxide film. The silicon oxide film is photolithographically exposed and an insulating spacing layer formed on the exposed region side, thus limiting an active region. Then the collector thin film is exposed, using the existing structure as a mask, and a lateral auxiliary film formed for component separation. An ion implantation of a dopant forms a selective collector region (10) in the active region. Then the auxiliary film is removed, the exposed part etched, and a separating, flat trough (17) is formed. Then a side polysilicon film (18) and a self aligning base are formed. A heat treatment after th formation of the collector sink follows which provides an oxide film on its upper section and activates dopants within the collector sink.

Filed: 1997-06-06
Abstract: Registration of the movement of a micro object (11), which has at least a periodic movement within the micro field cage of a micro electrode assembly (12), uses a microscope which gives a high magnification of the image of the object on \- 1 detection system (18). The detection registers a part area of the object, and a detection signal takes a number of movement periods of the object in a time span, to be passed for Fourier and/or correlation analysis. Also claimed is an apparatus to determine the movements of a micro object (11) in a micro field cage of a micro electrode assembly (11). A microscope (13) gives a magnified image for a detection system (18) to register a part area of the object. A signal processing and computer unit processes the detection signals with a Fourier and/or correlation analysis.  The image of the object is projected on to the detection system by an optical mechanism. At the detection system, a part area of the object is registered, using  <= 50% of the total object surface area. The image is formed by a microscope, a video system and a display monitor. The detection unit has \- 1 photo element, at the screen surface of the monitor in a part area of the displayed object. At least two photo elements are used, spaced apart at the object image, and the phase shift between the correlation signals is established from the photo element detection signals. The image projection of part of the object area is shown on a detection unit in the light path of the microscope. The objects under observation are suspended micro particles in electrical high frequency field cages.
