Patent CA-2071774-A1 (CA)
Inventor: TERAUCHI KIYOSHI
IPC: F04B27/18
Filed: 1992-06-22
Abstract: A slant plate type refrigerant compressor, such as a wobble plate type refrigerant compressor, with a capacity or displacement adjusting mechanism is disclosed. The capacity adjusting mechanism includes a valve device having an expandable/contractable bellows responsive to crank chamber pressure and a valve element fixedly attached to one end of the bellows to directly control the closing and opening of a passageway which connects a crank chamber and suction chamber. The bellows has a first effective pressure receiving cross-sectional area responsive to crank chamber pressure. The valve element has a second effective pressure receiving cross-sectional area responsive to suction chamber pressure. The second effective pressure receiving cross-sectional area of the valve element is approximately equal to or greater than 80% of the first effective pressure receiving cross-sectional area of the bellows so that the range of variation in the suction chamber pressure is sufficiently decreased during the capacity control stage of operation of the compressor, thereby controlling the air conditioning in a passenger compartment of an automobile in an efficient and effective manner.

Title: Multiplexed coded modulation with unequal error protection
Inventor: CALDERBANK ARTHUR R
IPC: H04N21/2383
Filed: 1992-11-25
Abstract: In a time-division-multiplexing communications system, which transmits information from various sources in different time-slots, additional information is transmitted by varying the pattern of time slot assignments in accordance with a set of rules. As a result, the assignment pattern by which time slots are assigned to each of the various sources of information, conveys additional information. Specifically, a High Definition Television (HDTV) transmission system is constructed in which picture information is transmitted by time-division-multiplexing between two different, and disjoint, signal point constellations. Additional information is conveyed by the rule for switching between the different signal point constellations.

Title: Buried heterostructure lasers using mocvd growth over patterned substrates
Inventor: BERGER PAUL R
IPC: H01S5/00
Filed: 1992-12-08
Abstract: This invention pertains to buried heterostructure lasers which have been fabricated using a single step MOCVD growth of an MQW laser structure over a pattern etched GaAs substrate.  The wet chemical etching of grooves having a dovetailed cross-section and being parallel to the [011] direction in GaAs substrates produced reentrant mesas which resulted in isolated laser active regions buried by the AlGaAs cladding layer.  The 250 µm long uncoated lasers emit at about 1 µm. Lasers with coated facets have threshold currents of 20 mA and emit >100 mW per facet under room temperature operation.  The external differential quantum efficiency for currents of from 30 mA to about 50 mA is found to be nearly independent of temperature in the range of 10°C to 90°C suggesting a low temperature dependence of leakage current.

Filed: 1993-06-09
Abstract: A gate array architecture is disclosed that utilizes significantly less silicon area than the prior art. The core cell (100) includes a four transistor arrangement in which a substrate tap (308) is located adjacent to the transistor pair. This provides for a more "symmetric" cell array than those in the prior art. Through the placement of the taps (304, 308, 314) outside of the transistors the power line connections can be routed in a simple and efficient manner. In addition the gate array architecture mirrors pairs of transistor columns (302, 306, 310, 312) for the sharing of substrate taps (308) between pairs of columns. This mirroring feature further reduces routing complexity.
