IPC: F02P5/153
Filed: 1981-06-15
Abstract: PURPOSE:To discriminate presence of knocking precisely and to control the ignition timing properly by making a signal from a knocking decision signal generating circuit intermittent by means of a switching circuit and controlling the intermittence ratio according to operation conditions suchas R.P.M. CONSTITUTION:A knocking signal is inputted into a noise signal generating circuit 4 and a comparison circuit 6 via a filter signal generating circuit 2. It is half-wave rectified and amplified with the ratio of resistance 104 to 105 to become a positive half wave. It is leveled off by an integration circuit made up of a resistance 111 and condenser 112, and then amplified by resistance, 113 & 114, and an operational amplifier 115 in order to generate a noise reference signal.

Title: Optical multiplex recording method
Inventor: MIYAUCHI YASUSHI
IPC: G11B7/24041
Filed: 1986-04-23
Abstract: PURPOSE:To attain multiple recording at one and same location by using a recording film including certain kinds of substances with different melting points or transposition temperature. CONSTITUTION:The recording film formed by the combination of some kinds of crystals with different melting point of transposition temperature is used for the recording medium and in selecting properly the power at recording, number of recording information is increased by the number of kinds of crystals at maximum. This is because the molten crystal differs from the magnitude of power at the recording. The number of stepwise reflectances is obtained by the number of kinds of crystals such as reflectance '0' at the complete crystal state, final reflectance '1' when the crystal with the lowest melting point is molten and the reflectance is decreased, and the final reflectance '2' when the crystal with the 2nd lowest melting pint is molten and the reflectance is lowered, and so on. Since the change in the reflectance is caused at one and same location, multiple recording is attained. Even when films whose crystal differs from the melting point are laminated, multiple recording is attained similarly.

Title: Restoration of carrier signal from modulated input signal
Inventor: MARKARIAN GAREGIN
IPC: H04L27/227
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To demodulate the carrier phase of a high-order M-ASK modulation system where the value of M is larger than '4' by obtaining the phase control signal of a voltage controlled oscillator through the use of combination of a function circuit, a mixer and an addition circuit. SOLUTION: Mixers 26 and 27 detect the I/Q components of a terminal input 25. A controller 126 generates first and second coordinate address values for addressing read-only memory 128 on a digital value obtained by A/D-converting a signal integrated in integrators 30 and 35. A digital processor 124 converts a coefficient which is read from the memory 128 into a control signal (a) of a voltage controlled oscillator VCO 28 with a corresponding digital value by a prescribed operation expression on high-order M. It is sent to VCO 28 through a low pass filter LPF 58. A phase difference between the carrier phase of an input modulated signal and the phase of VCO 28 is represented by the control signal (a) which the digital controller 124 obtains from the stored coefficient. Then, the carrier phase is restored by controlling VCO 28.
