Title: Overcurrent protector for field effect transistor
Inventor: KOMATSU SHUNICHI
IPC: H02H7/12
Filed: 1992-06-30
Abstract: PURPOSE:To provide an overcurrent protector for FET which can protect a FET (Field Effect Transistor) accurately regardless of fluctuation of ON resistance and the like of the FET without requiring sufficient margin for the rated current. CONSTITUTION:Parallel-connected FETs 112, 114 are connected, respectively, in series with current detecting resistors 136, 137 for detecting the currents flowing through the FETs 112, 114. The currents thus detected are then compared through op. amps 125, 126 with reference values 128, 129 thus detecting overcurrent. Since overcurrent is detected independently for each system with no influence of the value detected for other FET system, accurate overcurrent detection/protection is realized.

Title: Automatic gain controller
Inventor: UZAWA SHIGEYUKI
IPC: H03G3/20
Filed: 1990-07-02
Abstract: PURPOSE:To reduce the influence of a pulsative single noise and to improve an S/N by controlling the amplification factor and offset of an amplifier based on the mean value and dispersion of an input signal. CONSTITUTION:The output signal OUT of the amplifier 2 is converted to a digital signal at an A/D converter 4, and is sent to a read only memory 5 as an address signal. An adder 7 adds one on data at the correspondent address of histogram memory 6 at every access to the histogram memory 6 by the read only memory 5. Such operation is repeated for a constant period decided in advance. A mean and dispersion detector 8 finds mean and dispersion from the histogram of the histogram memory 6, and multiplies them by a coefficient set in advance and sends them to the amplifier 2 as an offset control signal S and an amplification factor control signal G, respectively. Thereby, the S/N resistant for the pulsative noise can be obtained.

Title: Horizontal output circuit
Inventor: OCHIAI MASASHI
IPC: H04N3/23
Filed: 1987-07-13
Abstract: PURPOSE:To achieve right and left bobbin distortion corrections and to reduce raster distortion and inverse trapezoidal distortion by changing the discharge current of an S-shape correcting capacitor into parabola shape in the vertical period by means of a modulation source. CONSTITUTION:The voltage -VCs' across a second S-shape correction capacitor C's is discharged through a modulation source A, then the voltage VCs across a first S-shape correction capacitor Cs, becomes lower, accordingly, a horizontal deflection current iy is also decreased. When said discharge current is decreased, the -VCs' rises, the VCs and the iy is also increased. Through above processing, a discharge current iD from the second S-shape correction capacitor C's is changed by the modulation source A into a parabola shape in the vertical period, so that the deflection current iy is also changed into a parabola shape in the vertical period in order to execute the right and left bobbin distortion correction. Furthermore, since no correction transformer is used, neither raster distortion nor inverse trapezoidal distortion will occur.

CONSTITUTION:In a microcomputer 5 at engine operation time, it is decided whether a condition decreasing a noise level is realized or not by using detection signals of, for instance, an engine speed and air pressure in an intake manifold or cooling water temperature, and when the concerned condition is realized, a noise gate is spread from 100 deg. to 150 deg. so as to contain a period, where an influence of valve seating vibration or the like appears in an output signal of a vibration sensor 1 despite presence of knocking, that is, a period where a large difference is generated between output levels from the vibration sensor 1 at sensor fail time and normal time. An angle change of this noise gate is realized by changing a preset value of a timer for creating the noise gate. Sensor fail is detected based on the noise level in the noise gate.
