Title: Refrigerating apparatus, and refrigerator control and brushless motor starter used in same
Inventor: HAMAOKA KOUJI
IPC: H02P6/182
Filed: 1996-03-14
Abstract: When a lock detector detects a locked state of a DC motor in a starting stage, a torque increasing circuit immediately selects a starting sequence pattern of an output torque that is greater in magnitude by one preselected step, and outputs the selected output torque to a starting sequence controller, so that a compressor can be restarted speedily without repeating starting failures. A compressor, driven by a DC motor, has a shell of an internal pressure approximately equal to the pressure of an inhalation gas. An inverter is provided to make the speed of the DC motor variable. A rotational frequency setting circuit sets the rotational frequency of the DC motor to a frequency that is not greater than the frequency of a commercial power source when the internal temperature of a refrigerator is stabilized. By this construction, the power consumption can be remarkably reduced.

Patent CA-2203015-A1 (CA)
Inventor: MARTIN RONALD G
IPC: H01M8/02
Filed: 1995-09-21
Abstract: The reactant flow field on the cathode side of a fuel cell assembly is formed from a plate made from carbon particles that are bonded together by a fluorocarbon polymer binder. The cathode reactant flow field is non-porous, and is hydrophobic due to the presence of the polymer binder. The carbon particles are preferably carbon flakes which pack together very tightly, and require only a minor amount of the polymer binder to form a solid plate. The plate will provide cathode reactant flow channels, will conduct electrons and heat and will minimize acid absorption in a fuel cell stack due to its hydrophobic nature.

Title: Communication method
Inventor: OHNO RYUICHI
IPC: H04L29/08
Filed: 1997-09-30
Abstract: A method of increasing the network use efficiency of computer communication and reducing the limitation of byte stream in a transmit/receive request.          A virtual circuit is established between protocol modules such as applications for providing the communication function between softwares to mate one transmit request with one receive request.  By returning an acknowledgement in a unit of request, any vain acknowledgement can be avoided and even in the case of asynchronous transmission/reception, a request which is completed in transmission/reception can be ended immediately, thus permitting efficient data transfer.          Even when the transmit request length and the receive request length differ from each other, reliable communication of a request having a smaller request length can be ensured between mating transmit and receive requests.        Further, in the case of synchronous transmission/reception, by copying only the latter half of a transmission buffer and returning a virtual ACK to the transmitting side when reception of the former half ends, the acknowledgement need not be waited for, thus permitting efficient data transfer.
