Inventor: ODAKA HIROBUMI
IPC: F25B9/14
Filed: 1987-12-04
Abstract: PURPOSE: To enhance durability of a compressor by causing a low pressure helium gas to be cooled and then sucked by the compressor. CONSTITUTION: A high pressure CFC discharged from a small compressor 13 of an auxiliary refrigerating machine 12 is cooled to be turned into a high pressure refrigerant by a fan 16 in a capacitor 14. This high pressure refrigerant is sent through a piping 17 into the direction of arrow to pass through a pressure reducing valve 15 thereby to be turned into a refrigerant of low pressure and low temperature. The high pressure refrigerant is further sent to remove heat of helium in a piping 1 of a helium refrigerating device 10 in a heat exchanger 8, and returned to the small compressor 13. In this manner, since the helium of the helium refrigerating device 10 in the heat exchanger 8 is removed of heat and cooled close to approximately 0 deg.C, a compressor 2 is cooled by the helium by sucking it into this cooled helium compressor 2.  The helium directly cools a heat generating cylinder and a rotor in the compressor 2, and therefore, cooling efficiency is high, and overheating of the compressor 2 is prevented.

Title: Differentially matched filter with small size and low position
Inventor: CHRIS BURIIKUREI
IPC: H04B1/707
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a matched filter(MF) for code division multiple access(CDMA) by reducing its forming area. SOLUTION: The matched filter, which uses a differential coefficient sequence to apply inverse spread to a spread spectrum signal and filters the spread spectrum signal, is configured with a differential sequence of a coefficient sequence consisting of a product between a prescribed coefficient sequence and a prescribed code sequence. In the coefficient sequence having a very high correlation with a square wave of a period of 4 (repetition of [+1, +1, -1, -1]), the product between the sequence and the square wave has less transition than the original sequence. Applying a differential technology to the sequence obtained by multiplying the square wave with the coefficient sequence can obtain many zero-taps than the case with application of the differential technology to the original coefficient sequence. As a result, the number of entries to an adder tree can be decreased.
