Abstract:
A use condition of gas equipment is monitored. An abnormality determination unit 26 determines whether or not a use flow volume obtained by detecting a flow velocity obtained by measuring a signal transfer time in a medium using a flow velocity detection unit 17 and converting the detected flow velocity into a flow volume using a flow volume calculation unit 25. When the shutoff unit 27 shuts off a fluid path 1 when it is determined that there is abnormality, a return signal is output from a return unit 28 to a shutoff unit 27 in order to use the gas again by opening the fluid path. Simultaneously, when a return time-counting unit 29 starts the time-counting operation, and then, a predetermined time period has been elapsed, the flow volume calculation unit 25 determines whether or not a predetermined flow volume of greater flows in order to identify whether or not all of the gas plugs of the gas equipment connected to the downstream of the gas shutoff apparatus 27 are closed. The leakage determination unit 30 determines that there is leakage when a predetermined flow volume or greater is detected, and a driving signal is output to the shutoff unit 27 to close the fluid path 1.

A data producing device in a signal reproducing apparatus, comprises a shift register supplied with synchronizing signals and codes which are time-sequentially reproduced from a recording medium, synchronizing signal detectors supplied with the synchronizing signals from the shift register, data transfer circuits provided in parallel with respect to each other and in series with the synchronizing signal detectors, and a control circuit for controlling the data transfer circuits so that a data is selectively read out and produced from a desired data transfer circuit among the plurality of data transfer circuits. The reproduced synchronizing signals and codes are transferred to the shift register and are read out from the shift register in response to a clock pulse having a predetermined frequency. The number of the synchronizing signal detectors is equal to the number of kinds of the synchronizing signals, and the synchronizing signal detectors are provided in parallel with respect to each other. Each of the synchronizing signal detectors detect a specific synchronizing signal. A data in a predetermined code among the codes supplied to the data transfer circuits is transferred to the data transfer circuits, when a synchronizing signal for discriminating the predetermined code is detected in the synchronizing signal detectors and supplied to the data transfer circuits.

About 5 to about 95 mole % of the reactive compound is replaceable by a dicarboxylic acid.The cross-linked resin may be usable for the production of machinery parts such as rolls and gears and embedded moldings of electrical machinery and apparatus parts as well as for electric insulating materials and dental uses. The cross-linked resin may further find applications in, for example, adhesives and various coating compositions.
Abstract:
A synchronizing signal detecting circuit is used in a digital signal transmitting system which transmits a digital signal in which signals are time-sequentially multiplexed in terms of blocks, where each of the blocks are made up of digital data which are information signals subjected to a digital modulation, a synchronizing signal having a fixed pattern, and an error checking code arranged at a location separated from a location of the synchronizing signal by a predetermined number of bits. The synchronizing signal detecting circuit comprises a counter which is reset when a synchronizing signal detection output which has been discriminated as being correct by use of the error checking code is continuously obtained for N times, where N is a natural number greater than or equal to two.

Abstract:
In a circuit arrangement for a disk player of the type arranged to reproduce information prerecorded in the form of pits, a variable gain circuit for changing the frequency characteristic of the reproduced signal is provided. The level of the reproduced signal is detected at high and low frequencies so as to produce a control signal the voltage of which varies in accordance with the difference between the level of the high frequency signal component and the level of the low frequency component. The control signal is then applied to the variable gain circuit receiving the reproduced signal so that the frequency characteristic of the reproduced signal will be controlled. Thus, the level of the reproduced signal is boosted at its high frequency range.
