Abstract: In transmitting and receiving signals between a plurality of units in a information processing system, signals can be transmitted and received between circuits operated by asynchronous clocks which are the same in period (frequency) but not necessarily to be the same in phase, thereby permitting the information processing system to operate with a shorter clock period. A delay circuit arranged in the communication path is so controllable that the data sent out in synchronism with the clock signal of a transmitting unit is correctly retrieved in synchronism with the clock signal of a receiving unit. Further, data having a predetermined simple pattern is sent out in synchronism with the clock signal of the transmitting unit, and it is decided whether the data has been correctly received by the receiving unit. The delay circuit is automatically controlled by use of the result of decision.

Abstract: A refrigerating machine oil composition suitable for a compressor using a hydrofluorocarbon as a refrigerant, which comprises 100 parts by weight of a polyol ester as a base oil, from 7.0 to 15.0 parts by weight of a phosphate, and from 0.2 to 3.0 parts by weight in total of a 1,2-epoxyalkane and/or a vinylcyclohexene dioxide. The use of the refrigerating machine oil composition improves wear resistance of sliding portions of compressors and is free from the formation of sludges derived from the polyol ester used as a base oil of the oil composition.

Abstract: A data processing system having a logic LSI, a plurality of memory LSIs and a circuit which eliminates delays in the time at which data read out form the memory LSIs reach the logic LSI. The circuit includes variable delay circuits for delaying the data signals read out of the memory LSIs. A control circuit start monitors the time when the data read out of the individual memory LSIs arrive at flip-flops which output the data to the logic LSI. The delay times in the variable delay circuits are controlled by the control circuit for the individual memory LSIs so that the times the data read out from the memory LSIs reach the logic LSI may coincide with a predetermined standard time. Thus, the read data from the individual memory LSIs are caused to reach the flip-flops simultaneously.

Abstract: An information processing system includes a plurality of functional blocks (neurons) and a data bus for transmitting in common the outputs of the individual functional blocks (neurons). Data transaction among the functional blocks (neurons) is performed through the data bus on the time-division basis. For preventing the outputs from conflicting or competition, addresses are assigned to the individual blocks (neurons), respectively, so that only the functional blocks (neuron) having the own address designated by the address signal supplied through an address bus outputs data signal onto the data bus, while the other functional blocks (neurons) receive the information on the data bus as the signal originating in the functional block whose address is designated at that time point. The addresses are sequentially changed. During a round of the address signals, data are transmitted from given functional blocks (neurons) to other given functional blocks (neurons).

Abstract: The present invention provides a clock signal supply method and system. A reference signal and a synchronizing signal are generated, as well as a clock signal, at a clock signal generating source end. Both the reference signal and the synchronizing signal have a period longer than that of the clock signal. The clock signal at a clock signal destination end is frequency divided in synchronism with the synchronizing signal to provide a sample to be compared with the reference signal. The resultant frequency-divided signal is compared with the reference signal in phase. A delay control is made for the clock signal in accordance with the result of the comparison to adjust the phase of the clock signal at the signal destinations.
