Patent EP-0341980-A2 (EP)
Inventor: BAKER DONAL EUGENE
IPC: H02M7/06
Filed: 1989-05-09
Abstract: Voltage regulation of a DC electrical power source having a generator (10) with an exciter field coil for producing an AC output voltage which is rectified to produce a DC output voltage, is accomplished by producing voltage signals proportional to the AC output voltage of the generator and the current in the generator exciter field winding, and combining these signals to produce a control signal. An additional voltage signal proportional to the DC output voltage of the power source is compared to a DC reference voltage signal to produce a trim error voltage signal. The trim error voltage signal is combined with an AC reference signal to produce an additional control signal. These control signals are compared and the result of that comparison is used to control the current in the generator exciter field winding.

Abstract: A patch sensing toner concentration control method and apparatus is provided in which the optical density of reproduction output can be changed without changing the quantity of toner that is deposited on the photoconductor's test patch area. The test patch area receives toner as the patch area passes through a developer station under the influence of a patch development electrical field or vector. Light that is reflected from a bare photoconductor area is compared to light that is reflected from a toned test patch area. The ratio of these two reflected light intensities is used to control the addition of toner to the developer station. Optical density of the reproduction output is changed by changing the toner concentration in the developer station. The toner concentration control method and apparatus of the invention is constructed and arranged to require a fixed or constant ratio of light reflection as an indication of proper toner concentration, independent of the absolute value of toner concentration. Toner concentration, and thereby optical density of reproduction output, is changed by changing the magnitude of the patch development vector, while maintaining the reproduction development vector constant.

Abstract: A thermoformable mat, e.g., a mat of resinated fiberglass, is compressed and shaped into a contoured object, e.g., a shell for an automobile headliner, by this process. The mat is compressed between two dies that have been preheated. At least one of the dies is perforated. Superheated steam (e.g., at 80 psig and 600° F.) is ejected from the perforations into the mat, thereby quickly raising the mat temperature to its thermoforming point. After the mat is set into the contoured shape, the dies are reopened and the formed mat is removed. If the mat that is used contains a thermoplastic adhesive, the mat is cooled to below the adhesive's melt print before the dies are opened. This can be done by applying a vacuum to the perforated die and pulling ambient air through the mat.

Abstract: A high speed digital telemetry system (10) includes a transmitter (12) and a receiver (14), at least one of which is adapted for use in an implantable device. The transmitter includes a data encoder (14), modulator (16), transmitting coil (20), and transmitting coil drive circuit (18). The data encoder examines prescribed incoming data bits and prior encoded data bits, generating an encoded data stream (36) that includes a data transition only when a prescribed correlation is noted amongst the examined bits. The modulator modulates a carrier signal (34) with the encoded data stream, causing a phase reversal of the carrier at each data transition of the encoded data stream. The transmitting coil drive circuit applies the modulated carrier (38) to the transmitting coil. The receiver includes a receiving coil (22) and associated amplifier (24) and bandpass filter (26) for detecting the transmitted modulated carrier. The bandpass filter is centered at the frequency of the carrier, passing the carrier only when no phase reversals are present. This results in an on-off signal at the frequency of the carrier. An AM detector (28) detects when the signal is present and when it is not, and appropriate decision logic (30) applies a suitable acceptance criteria to the detected signal to define the received binary data.

Abstract: In an optical unit (2) used for in a laser beam printer, a laser beam generated by a laser diode (12) is converted by a group of conversion lenses (10) into a laser beam having a predetermined-size cross section. The laser beam is directed toward a photosensitive body (90) by a scanner (54), so as to scan the photosensitive body at a nonuniform speed. A focusing lens (72) focu­ses the baser laser beam on the surface of the photosen­sitive body. The conversion lenses (10) includes at least one aspheric-surface glass lens. The mirror (68) of the scanner (54) is convex and is so formed as to satisfy R/Z < 0.5, where R is the maximum radius of curvature with respect to a main scanning direction, and Z is the shortest distance between a point of reflection (or a point of deflection) and an object to be scanned. The focusing lens (72) is an aspheric-surface lens having a toric surface which is rotation-symmetric with reference to an axis extending in the main scanning direction.

Abstract: An apparatus (10) and method provide automated collection and transfer of particles from a liquid suspension to a glass slide for visual examination. A solution which contains particles, for example cells, is drawn through a filter element [68 (FIG. 2)] so that particles too large to pass through the filter element collect against a first surface of the filter element. A transfer fluid, such as alcohol, is applied from a second surface of the filter element to the first surface, to transfer cells from the filter element to a glass slide positioned adjacent the filter element. An alternative transfer mechanism applies a selected pneumatic signal to the filter element for transferring collected cells to the viewing slide. The apparatus includes a device [66 (FIG. 2)] for dispersing the liquid suspension of particles prior to the collection process and particles collect against the filter element with a spatial distribution advantageous for visual examination. The transfer operation maintains this spatial distribution. The cell-dispersing device and the filter element are on a common structure (22), for unitary movement, and which is readily disposable and replaceable for each sample of particles.
