Title: Television signal decoder
Inventor: KAGEYAMA TEIJI
IPC: H04N7/015
Filed: 1987-12-23
Abstract: PURPOSE:To receive the existing television signal without hindrance and to obtain a pattern having a longer aspect ratio than that of the existing system by providing a means applying synchronizing detection to a television signal and a means applying times axis compression and time axis expansion. CONSTITUTION:The signal sent from a sender side is received by an antenna, frequency-converted into an intermediate frequency band by a tuner, band-limited by a 1st filter and subject to synchronizing detection by a 1st detector by using a carrier I1 and becomes a main signal. Moreover, the output of the tuner is given to the 2nd filter, where its band is limited, subject to synchronizing detection by a 2nd detector by using a carrier I2 and the detection output becomes a multiplex signal. Then the main signal and the multiplex signal are given to a signal processing circuit and the time axis processing and time axis adjustment opposite those to the sender side are applied respectively in the time axis expansion circuit 23 and time axis compression circuits 22, 26 and the output of the time axis compression circuits 22, 26 is separated into a luminance signal Yc and a chrominance signal Cc by a YC separator circuit 27. Thus, the existing television broadcast is received without hindrance and the pattern with a longer wide aspect ratio is obtained.

Filed: 1992-12-07
Abstract: PURPOSE:To prevent secondary accidents due to the occurrence of an earthquake by constituting control means such that as the occurrence of an earthquake is detected by a seismoscopic sensor, a fuel pump is stopped. CONSTITUTION:A seismoscopic sensor 62 for detecting an earthquake is provided in a hot air supply unit S, and a detection signal is input into control means 57.

Connected to a normally open contact side of the seismoscopic relay is a lamp 64 for indicating a stopping state due to an earthquake. When the normally closed contact of the seismoscopic relay is opened by a detection signal from the seismoscopic sensor 62, an electric current for a power circuit for a control unit is shut off. Then an electric current for a safety valve 53 biased toward a closed side and a fuel pump 52 is shut off, so that the safety valve 53 is closed and driving of the fuel pump 52 is stopped. Thus as an earthquake is detected by the seismoscopic sensor 62, the control means 57 closes the safety valve 53 and stops the fuel pump 52.
