Title: Copy guard generator
Inventor: YODA SHINJI
IPC: H04N5/92
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To obtain a corrected video signal with excellent guard performance without deteriorating gradation of a video signal. SOLUTION: A copy guard signal generating circuit 11 generates a pseudo synchronization pulse and an AGC(automatic gain control) pulse. A subtractor 13 subtracts a prescribed DC level from a pulse pair in a timing of the AGC pulse. Thus, a level of the AGC pulse is decreased more than a peak white level. An output of the subtractor 13 is superimposed onto digital image data by an adder 14 and converted into an analog signal by a D/A converter 16. Thus, even when the dynamic range of the D/A converter 16 is set to the peak white level, D/A conversion without distortion is attained. An adder 17 adds a DC level to an output of the D/A converter 16 and provides an output of the result. Since the peak level of the image is in matching with the dynamic range of the D/A converter 16, gradation of the image is not deteriorated.

Title: Knocking detector for internal combustion engine
Inventor: TOKI SHIYUUICHI
IPC: G01M15/00
Filed: 1980-04-04
Abstract: PURPOSE:To eliminate malfunction by having a comparing means which generates a knocking signal when the level of an engine vibration signal exceeds a reference voltage. CONSTITUTION:Prior to starting of an engine, no engine vibration signals exist and therefore, the potential of a capacitor C generating the reference signal of a reference voltage generating circuit 4 is at a low level. When a motor start switch MST is turned on, the voltage of a battery BT flows as a correction signal to the capacitor C via a diode D and a resistance R4, then the potential of the capacitor C reaches a prescribed value. On starting of the engine, the motor switch MST is returned to the off-state and therefore the generation of the correction signal stops. In the circuit 4, the engine vibration signal is inputted and the voltage having undergone half-wave rectifying, dividing and voltage following is applied via the resistance R3 to the capacitor C. Since the potential of the capacitor C has already the prescribed value, it immediately follows up the voltage corresponding to the average level of the engine vibration signal.

Title: Combustion deciding method for spark ignition internal combustion engine
Inventor: ISHIDA TETSURO
IPC: F02D45/00
Filed: 1989-02-23
Abstract: PURPOSE:To reliably predict or detect abnormal combustion and to prevent the occurrence of knock by a method wherein when it is impossible to decide a combustion state from a rate of change in a pressure in a cylinder, quality of a combustion state is decided according to the high frequency component of a detected pressure-in-cylinder signal. CONSTITUTION:A presage type combustion deciding means 14 inputs a pressure-in- cylinder signal detected by a detecting means 10 and through a low-pass filter 12 and a crank angle signal from a detecting means 11. The deciding means determines a rate of change in a pressure in a cylinder and further a fall time, decides the degree of margin of knock based on a reference value, and controls a combustion state by means of a control means 20 according to the decision. Meanwhile, a backup combustion deciding means 18 decides quality of a combustion state according to the high frequency component of a pressure-in-cylinder signal inputted through a band-pass filter 16, and outputs a deciding signal through a switching means 15 to a control means 20 when decision based on a rate of change in a pressure in a cylinder is impossible to make during high speed running of an engine. This constitution prevents the occurrence of knock and enables rapid and accurate decision of the occurrence of abnormal combustion.

IPC: H01F7/20
Filed: 1989-02-23
Abstract: PURPOSE:To miniaturize equipment by allowing an air or water passage to penetrate the inside of an annular stator on which a field coil is wound and connecting the coil to an AC power source. CONSTITUTION:When a three-phase voltage is impressed on the field coil 4 of the stator 1, a line of magnetic force is generated in turn between the opposed three sets of field cores 2.
