Title: Descramble mode switching system
Inventor: IKEDA MIYUKI
IPC: H04N7/167
Filed: 1984-06-08
Abstract: PURPOSE:To perform switching in a high speed to prevent flickering of a picture by detecting directly a scramble modulation period from a scramble video signal and switching the scramble mode. CONSTITUTION:Video signals of modes A and B are subjected to waveform shaping by a waveform shaping circuit 13 as shown in figures (c) and (d). When the input of a shift register 15 is the signal of the mode A, the output of a terminal 22 is always in the low level because only one leading edge exists during the period of the high level. When the input is the signal of the mode B, the output is as shown by a broken line in a figure G because two leading edges are generated. This signal is latched in a DFF16 which uses a pulse in a figure H as the clock, and the detection signal of the high mode is obtained in an output terminal 22. Thus, descramble mode switching is performed at the moment of scramble mode switching.

Title: Method and apparatus for detection of blown out vent valve of internal combustion engine
Inventor: ENOHARA KENJI
IPC: G01M15/04
Filed: 1981-07-25
Abstract: PURPOSE:To simply and accurately detect a blown-out vent valve, by detecting period of fuel jet or ignition and taking a gate signal for blown-out pickup as a synchronizing reference signal. CONSTITUTION:When a fuel jet period detection signal from the 2nd acceleration meter 6 and a signal processing circuit 9 is applied as a synchronizing reference signal, a preset counter 10 counts a clock pulse is a frequency in response to the number of revolutions of the internal combustion engine with a tachometer 7 and a voltage-frequency converter 8. The counter 10 outputs a signal P2 when the specified preset value is coincident with the count value, i.e., blown-out start period, and sets the RS type FF12. This FF12 is reset with a preset counter 11 determining the gate period to control a gate circuit 14 in which an output of an acceleration sensor 5 inputs, which detects vibration or sound at the outside of vent pipes through the set output of the FF12. Thus, even if the number of revolutions of the internal combustion engine is changed, blown-out can simply and surely be picked up and detected without any encoder by taking the fuel jet period as a synchronizing reference.
