Title: Multi-track magnetic signal reproducing apparatus
Inventor: TAKEUCHI HITOSHI
IPC: G11B5/00
Filed: 1993-10-18
Granted: 1997-05-13
Abstract: In a multi-track magnetic signal reproducing apparatus, a plurality of MR heads including MR (Magneto-Resistance Effect) elements are provided, corresponding to tracks on a magnetic tape. At the time of reproduction, constant current from a constant-current power supply is sequentially supplied, as a pulse-shaped current for detecting a signal, to each MR element by switching a switch in response to a prescribed clock signal. An output voltage from each MR element, related to reproduction of a magnetic signal on a corresponding track, is sequentially provided to one input side of a differential amplifier. In the differential amplifier, the offset voltage of each MR element provided to the other input side and the above-described output voltage are differentially amplified, and only voltage due to the reproducing magnetic signal of each track is accurately extracted. Accordingly, the supply of pulse-shaped current effectively suppresses an increase in the amount of consumption current regardless of the number of tracks on the tape (or the number of heads), and since the amplifier is shared between the tracks, the number of necessary terminals for such a multi-track MR head is reduced.

Granted: 2000-05-09
Abstract: A general purpose programmable communications interface designed to support a wide variety of serial synchronous and asynchronous communication protocols. A universal protocol communications (UPC) interface is designed to operate on a VME bus in conjunction with a CPU board which contains the application software that utilizes the communications capabilities of the UPC interface. Per channel DMA is available on input/output lines of the interface together with bit level control for message processing so that a variety of bit oriented communications protocols may be supported by simple reconfiguration of the receiver/ transmitter of the programmable UPC interface. In a preferred embodiment, a dynamically variable bit length shift register is used to organize the received and transmitted data into serial packets of the appropriate size on a per channel basis independent of the actual width of the shift register.      Reconfiguration for different protocols is accomplished by simply changing a bit count value stored in a bit counter which counts the number of serial data bits received or transmitted in each data word by the dynamically variable bit length shift registers of the transmit and receive circuitry.

Granted: 2004-12-28
Abstract: A sports lighting fixture having improved light delivery characteristics includes an elongated bare arc tube, high intensity discharge lamp disposed near the apex of a parabolically shaped reflector member. The reflector is constructed of a non-metallic material and by the orientation and positioning of the lamp within the reflector, an essentially oval shaped light pattern is generated. A light transmissive cover is disposed over the open end of the reflector. When projected onto the playing surface of a sports field, the oval shaped light pattern translates to an essentially circular shaped pattern which allows for a more uniform and efficient overlapping of the multiple light outputs at the playing field level Louvers can be disposed within the reflector to further redirect any high angle light output into a lower angle which is more useful at the playing surface level.

Title: Cryogenic rectification process and apparatus for vaporizing a pumped liquid oxygen product
Inventor: MOSTELLO ROBERT A
IPC: F25J3/02
Filed: 1994-07-21
Granted: 1997-10-14
Abstract: A low temperature rectification process and apparatus in which a compressed gaseous mixture, for instance, air, is rectified to produce a lower volatility component in liquid form which is then pumped to a delivery pressure. After having been pumped, the lower volatility component is vaporized within a main heat exchanger. In order to effect the vaporization, a stream of the compressed gaseous mixture being cooled in the main heat exchanger is further compressed to form a further compressed stream. In order to minimize thermodynamic irreversibility within the main heat exchanger above a theoretical pinch point temperature thereof, a portion of the further compressed stream is removed from the main heat exchanger at or near the theoretical pinch point temperature and then is still further compressed and introduced at a level of the main heat exchanger warmer temperature than the theoretical pinch point temperature. Either the balance of the further compressed stream or some other stream of the compressed gaseous mixture being cooled is removed from the main heat exchanger and is then cooled to a temperature suitable for its rectification without further use of the main heat exchanger. Such removal reduces thermodynamic irreversibility within the main heat exchanger below the theoretical pinch point temperature.
