    摘要： 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.

    摘要： In a pay broadcasting system, data of a broadcast program is scrambled with a scramble key updated in a short period. The scramble key is encrypted with a first key assigned to the subscriber terminal. The first key is encrypted with a first master key set in the subscriber terminal. The security of a broadcast program stored for subsequent use in the subscriber terminal is enhanced as follows. A central station generates a second key-encrypted scramble key by encrypting the scramble key with a second key different from the first key and changeable in an interval shorter than a update interval of the first key; generates an encrypted second key by encrypting the second key with a second master key which has been commonly issued to subscriber terminals of the system; and broadcast the second key-encrypted scramble key and the encrypted second key together with the scrambled data of the program, the first key-encrypted scramble key and the encrypted first key in a multiplexed manner. When a broadcast program is to be stored, the subscriber terminal stores the scrambled data of the broadcast program and the second key-encrypted scramble key; decrypt the encrypted second key with the second master key into the second key, which is added to a stored program second key list. If the stored program is to be executed, the second key-encrypted scramble key is decrypted with a corresponding one of the second keys in the stored program second key list into a decrypted scramble key; and the scrambled data of the broadcast program is unscrambled with the decrypted scramble key.

    摘要： In a video signal processing apparatus for correcting time axis errors using a memory, with replacement of a horizontal sync signal in a video signal read out from the memory by a reference horizontal sync signal, data appearing in a vertical flyback period is not lost. A vertical flyback period detecting circuit functioning as an inhibiting means detects the vertical flyback period and produces a detection signal. An AND gate gates the detection signal and a reference horizontal sync signal generated from a sync signal generating circuit, so that a replacement of the horizontal sync signal is inhibited during the vertical flyback period, and an address, a time code and an ID code which have been inserted during the vertical flyback period are not lost.

    摘要： Disclosed is a two-cycle internal combustion engine including a protruding edge portion formed in a section of a lower side surface of an intake port which is adjacent to a pre-compression chamber of a cylinder. This protruding edge portion serves to deflect air-fuel mixture introduced into the pre-compression chamber through the intake port so as to direct it to a bearing portion provided between a piston and a connecting rod. Further, a cut-in groove is formed in the protruding edge section and is adapted to allow any liquid remaining in the intake port to flow into the pre-comparison chamber.
