Title: Distribution/exchange system for non-synchronizing signal
Inventor: TSURUTA TADAO
IPC: H04Q3/52
Filed: 1984-07-27
Abstract: PURPOSE:To exchange a non-synchronizing signal for a substantial CMI signal at a distribution stage for using a low speed switching element and to simplify the system constitution by lowering an apparent signal transmission rate. CONSTITUTION:When a CMI serial signal is inputted at the input-side terminal of a distribution stage, a clock is extracted from 32MCMI (CMI of 32m bit/sec) serial signal by an input-side timing circuit. This extracted clock converts the serial signal into 4-bit parallel signal with use of a S/P register. By this conversion, said parallel signal is made into an CMI signal of 8M bit/sec with an apparently low signal transmission rate, and a switching element capable of exchanging the 4-bit parallel signal for a signal of 8M bit/sec is used at a distribution stage. With use of the P/S register, the exchanged 4-bit parallel signal is converted into a serial signal by an output-side timing circuit, and transmitted to an output-side terminal as a 32MCMI serial signal with low signal transmission rate.

Title: Controller for resonance circuit
Inventor: KAWADA KAZUHIDE
IPC: H03J5/02
Filed: 1978-12-13
Abstract: PURPOSE:To simplify the procedure for an adjustment of a resonance circuit by  writing intial data in a frequency memory in adjustment mode and then by inhibiting the contents of the frequency memory from being modified in reset mode from  an external reset terminal. CONSTITUTION:This resonance circuit controller consists of frequency memory 6, controller 5, D/A converter 8, and power-failure detector 1; detector 1 receives power from power feeder 2 and when its level reaches a fixed voltage value, power- failure detection signal 3 is outputted. Controller 5 writes data, needed to adjust oscillator 10, in memory 6 by signal 3. To let oscillator 10 oscillate at a frequency corresponding data stored in memory 6, controller 5 reads data in memory 6 and its digital value is converted by D/A converter 8 into a voltage level, which is sent to oscillator 10 for fixed-frequency oscillations. If controller 5 malfunctions, controller 5 repeats the assigned operation by inputting reset signal 4, but the contents of memory 6 are never rewritten.

Abstract: PURPOSE: To improve a processing efficiency as the whole of the magnetic tape processing system by providing a tape mark detection circuit in a magnetic tape device.  
     CONSTITUTION: After the read output signal from magnetic tape 5 is converted into a data form to be sent to a magnetic tape control unit by a converter, the tape mark pattern is retrieved by tape mark pattern detection circuit 7. When the tape mark pattern is detected, tape mark pattern counter 8 is operated at the period of frame timer 9 of magnetic tape 1; and when the tape mark pattern of a prescribed number of frames is detected, tape mark detection interrupt indicator 10 is set to generate an interrupt signal to the magnetic tape control unit. During this time, patterns other than the tape mark pattern and the tape mark pattern below a prescribed number of frames are all ignored, and counter 8 is reset in record gaps on the magnetic tape.

Filed: 1990-06-15
Abstract: PURPOSE:To detect the passing position of a charged particle with high accuracy and to carry out continuous monitor without missing data by providing a data converting part receiving the outputs of (n) line sensors to the silicon substrate having the line sensors formed thereto. CONSTITUTION:A data converting part 11 receiving the outputs of (n) line sensors 2 is provided to the silicon substrate 1 having the line sensors 2 formed thereto and the outputs of (n) line sensors 2 are converted to serial digital signals by the covering part 11 and said signals are further converted to light multiple signals to be transmitted to a signal processing circuit system through an optical fiber 13. That is, the digital serial signals are transmitted within a time shorter than a cycle for sampling the states of respective measuring channels. Since the outputs of (n) measuring channels are transmitted as one signal, the number of connection cables is reduced to a large extent and, since the signal is transmitted during the sampling period of the states of the respective measuring channels, the passing position of a charged particle can be detected with high accuracy and continuous monitor generating no missing data becomes possible.
