Title: Surface acoustic wave filter
Inventor: KOJIMA YUUJI
IPC: H03H9/68
Filed: 1980-11-14
Abstract: PURPOSE:To avoid the effect of bulk waves and to achieve a filter with excellent characteristics, by locating in parallel an output transducer at a region other than the extension of an input transducer via a multistrip coupler, in a multichannel filter. CONSTITUTION:Surface acoustic waves generated 2 through the input of a composite signal from a tuner are converted for the transmission line with a linear coupler 3 and converted into electric energy. The energy is equally divided into transducers 4, 5 and greatly attenuates a sound carrier wave through a signal including carrier chrominance wave signals CC and video carrier wave PC. A filter consisting of the output transducer 5 passes through only the SC and PC and greatly attenuates signals other than the PC. The filter characteristics depend on the crossing width of reed screen electrode of each transducer and pitch and the like and an output signal is picked up from terminals 41-52. With this constitution, bulk waves passing through the coupler 3 do not give any effect on the output transducer and give excellent frequency characteristics and spurious characteristics.

Abstract: PURPOSE:To obtain an inexpensive stepping motor driving gear by driving a plurality of steeping motors by one driver. CONSTITUTION:In the case of driving a motor 1, a transistor (Tr) Q3 is turned on. In the case of exciting an A phase, an L signal is inputted to a gate G1 to cause a current to flow by the order of power supply Vcc TrQ3 A phase diode D7 TrQ1 resistor Rs; in the case that the current exceeds a preset value, the TrQ1 is turned off to cause a current to flow by the order of diode D6 A phase diode D3 power supply Vcc. Then the motor 1 and a motor 2 remain wired OR, but when a current of a loop L3 flows through the motor 1, a current to the motor 2 is impeded by a diode 11. In this way, the A phase of the motor 1 is excited.

Title: Data sampling circuit
Inventor: KOBAYASHI AKIRA
IPC: H03M5/04
Filed: 1982-09-16
Abstract: PURPOSE:To discriminate between a high and a low level corresponding to modulation measurement on the basis of the received wave of a digital data signal read out without influenced by temperature change and voltage fluctuation and to convert to a rectangular wave signal, by eliminating the need to adjust a circuit. CONSTITUTION:When the discrimination between the high and low levels of an input signal S'1 is made on the basis of a voltage VTH1 lower than a normal threshold value VTH0, the integral value of a signal SQ converted into the rectangular wave by a comparator 37 is positive. The output SQ of the comparator 37 is converted into signals S'Q and S'Q with TTL levels by an AND circuit 38 and an NAND circuit 41. An amplitude control circuit 41 compresses the level of the high level to the same level to obtain signals S'QCL and S'QCL. When the Zenor voltage of a constant voltage diode D1 is VZ and forwad voltages of diodes D12 and D13 are VF, the high-level amplitude VCL is limited to (VZ+VF). A one-chip dual-TR is utilized for the diodes D12 and D13 to realize the unbalanced detection of sampling data with less errors due to temperature change.

Filed: 1989-06-23
Abstract: PURPOSE:To attain inference restricting supervisory time and equipment to be supervised by starting optimum inference at every process of a batch processing and setting inference to be stopped as the process terminates. CONSTITUTION:When inference is executed and the cause of abnormality becomes clear, an abnormality prediction/inference device 18 issues the execution request of an unplanned sequence for restoring the cause of abnormality to an unplanned sequence retrieval/inference device 19. The unplanned sequence retrieval/inference device 19 which receives the execution request judges the content of the execution request, retrieves the optimum unplanned sequence by inference and outputs the result to an unplanned sequence starting device 22. It starts the unplanned sequence and registers processing results based on the unplanned sequence to batch results 29 through a sequence execution control 6. Since optimum inference is started at every process of the batch processing and inference is stopped as the process terminates, inference restricting supervisory time and equipment to be supervised is attained, and the detection and inference of abnormality, which is optimum for every sequence processing, can exactly be attained at short time.
