Title: Spread spectrum data transmission
Inventor: SEHIER PHILIPPE
IPC: H04B1/707
Filed: 1989-05-25
Abstract: A spread spectrum digital data transmisiion and reception system operates using offset quaternary phase shift keying (OQPSK). The data signal, differentially encoded and spread using a PN sequence, undergoes complex multiplication by a power of j prior to modulation with carrier exp(j2#f 0 t). At the receiver, multiplication by a power of -j occurs at 21, after demodulation, filter and sample unit 20. Tracking 26, acquisition 25 and phase recover 24 are thus simplified, all useful information being moved into the real channel.

Title: Process and apparatus for preparing metal layers
Inventor: TANAKA TADASHI
IPC: B22F7/04
Filed: 1991-03-28
Abstract: A method for producing a bimetal for use as a material in a plain bearing is disclosed which involves coating a copper. alloy powder 2 on to a backing steel 1 and then pre-heating this to a temperature near a Curie point of steel in a reducing atmosphere by high-frequency induction heating. The pre-heated backing steel and copper-alloy powder are then heated to a sintering temperature (i.e. from 770 DEG C to 950 DEG C) in either an electric resistance furnace or a gas furnace in a reducing atmosphere so that the copper alloy powder 2 is sintered. Thus a sintered copper alloy layer is bonded to the backing steel. <IMAGE>

Title: Air-conditioning apparatus having heat source unit and plural indoor units
Inventor: WATANABE SHIGEKI
IPC: F25B13/00
Filed: 1993-01-12
Abstract: In an air-conditioning apparatus, a cooling bypass (15) extends from a pipe portion between a water heat exchanger (5a, 5b, 5c) and indoor heat exchangers (34, 44, 54) of a refrigerating cycle to a low-pressure-side pipe portion of the refrigerating cycle. The cooling bypass is provided with a flow control valve (16). A discharged-refrigerant temperature Td and sucked-refrigerant temperature Ts of a compressor (1) are sensed, and the opening degree of the flow control valve (16) is zone-controlled in accordance with temperature Td or temperature Ts. When the sucked-refrigerant temperature Ts exceeds a predetermined value despite the zone-control, the opening degree of the flow control valve (16) is controlled and increased. By this control, the amount of refrigerant flowing through the cooling bypass (15) increases, and the refrigerant cooling effect on the low pressure side is enhanced. <IMAGE>
