Title: Data processor
Inventor: MURAMATSU KATSUTOSHI
IPC: G06F9/30
Filed: 1986-03-20
Abstract: PURPOSE:To shorten an instruction decoding time after a second operand and to improve a processing speed by introducing an instruction form to write in parallel plural operands to one instruction code instead of continuously using plural instructions only different in operand but the same in instruction code. CONSTITUTION:At an instruction buffer register 4, an instruction is anticipated by the control of an instruction anticipating control part 43 from a cash memory at an S unit 7. An instruction buffer control part 42 controls the shifting between instruction buffer registers based upon the signal from an instruction decoder 41 and without depending upon the instruction length, an instruction code part is set to a certain position of the instruction decoder 41. In the instruction decoder 41, a means to decrease the value of a number of paired operands designating part X each time execution is performed concerning one pair of the operands and detect that the execution is completed concerning all pairs of the operand of the instruction are included. Since only the extraction and execution of the paired operands may be controlled after the instruction code is decoded once, the processing speed after the second paired operands can be made faster than decoding successively the instruction code.

Title: Transmission system of data packet
Inventor: KISHIMOTO SEIJI
IPC: H04L12/413
Filed: 1983-04-12
Abstract: PURPOSE:To improve the utilization rate of a transmission line without requiring an expensive collision detecting circuit by giving the access right for packet retransmission to the transmission line to a node, which transmits data last, when packet collision occurs and retransmission of packets is required. CONSTITUTION:Nodes 1, 2, and 3 detect the carrier of the transmission line in CS11, CS21, and CS31 approximately simultaneously and confirm that data does not exist on the transmission line, and they start the data transmission. Since data 11, 21, and 31 from these nodes collide with one another just after the start of the transmission, a receiving node cannot output the acknowledge signal. When nodes 2 and 3 detect the carrier in CS22 and CS32 just after the end of the transmission, they discriminate the existence of data 11 from the node 1. Thus, if the carrier is detected just after the end of the data transmission in this manner, the node which continues the transmission to the last finds this fact after the end of the transmission even if data collision occurs.

Filed: 1994-03-31
Abstract: PURPOSE:To provide a method for optically measuring displacement amount which is high in measuring accuracy, easy to set an optical system and hard to be influenced by a stain and a break of a periodic pattern on the surface of a scale. CONSTITUTION:A periodic image pattern formed by projecting light to a scale is detected by an image sensor. A relative displacement amount and a relative displacement direction of the scale and the image sensor are detected from a change of the periodic image pattern. A measuring pulse-generating means 3 generates and outputs a measuring pulse corresponding to the periodic image pattern from an output of the image sensor, and a reference pulse-generating means 4 generates and outputs a plurality of reference pulses of each equal width in phases different by equal phases. Counting means 5 and 6 count a time of disagreement of each reference pulse from the measuring pulse. The counting results are compared by a comparing/detecting means 7 as to whether the time of longer or shorter. A phase of the measuring pulse is detected by a phase-detecting means 8 from a pattern indicated by each result obtained by the comparison/detecting means 7. The relative shifting amount and relative shifting direction are determined from a change with time of the phase.
