Title: Automatic gain control circuit and catv signal distributing amplifier
Inventor: YAGISHITA YUKIO
IPC: H04N5/00
Filed: 1993-06-28
Abstract: PURPOSE:To set a large sum total of electric power of all transmitted signals without causing any trouble of distortion and to ensure a satisfactory carrier/ noise ratio by controlling the gain of an amplifier in accordance with the detecting level of the preceding sum total of electric power. CONSTITUTION:The sum total of electric power of all signals is detected by a total power detecting circuit 32 among some of output signals of a down variable amplifier 31, and this detecting value is sent to a comparing part 33. Thus the detecting value is compared at the part 33 with the standard value of total power set in an all-channel transmitting state. Based on the result of this comparison, a gain control part 34 outputs a gain control signal to the amplifier 31 in order to control the power at a device standard level. Receiving the gain control signal, the amplifier 31 controls its gain to ensure a satisfactory carrier/noise while keeping the distortion degree set by the total power under the standard level and then sets a high transmission level.

Title: Demagnetizing method
Inventor: KARIYA NORIJI
IPC: H01F13/00
Filed: 1984-07-26
Abstract: PURPOSE:To perform the demagnetization of a magnetic shield more completely by a method wherein, after resistance value has reached a constant value by saturating the resistance variation of a thermistor, the full resistance value of the variable resistor connected to a demagnetizing coil in parallel is reduced. CONSTITUTION:The demagnetization current running on a PTC thermistor 2 increases the internal resistance of the PTC thermistor 2 having a positive temperature coefficient by the self-heat generation of the thermistor, and the demagnetization current is monotonously attenuated during the time t1. When the movable element of a variable resistor 3 is adjusted in the direction wherein its total combined resistance is made smaller by the output of a sequence control part 1 at the time T1 when said attenuation is almost stabilized, the greater part of the current runs to the variable resistor 3, the value of branched current running to the demagnetization coil 4 is completely zeroed, if the total combined resistance 3 is turned to zero. As a result, the demagnetization current can be adjusted arbitrarily to a very small value, thereby enabling to attenuate the residual magnetism to a very small value.

Title: Ignition device for internal combustion engine
Inventor: SATO HIROO
IPC: F02P5/155
Filed: 1987-06-24
Abstract: PURPOSE:To obtain lead and lag characteristics with high accuracy by connecting a second ignition controlling switch when the terminal voltage of a timer capacitor is higher than a reference voltage whereas disconnecting the switch when lower than the reference voltage. CONSTITUTION:As the engine speed is increased causing the time width of a defined angle width signal to exceed the time it takes for the terminal voltage of a timer capacitor 18 to reach a reference voltage, since a second ignition controlling switch 17 is disconnected a first ignition controlling switch 16 is disconnected, the switch 17 takes part in determining an ignition position. In this condition, an ignition position signal reaches a trigger level when the switch 17 is disconnected. With the time at which the switch 17 is disconnected after it is connected (the time it takes for the terminal voltage of the capacitor 18 to reach the reference voltage) being constant and since the position in which the switch 17 is disconnected is gradually delayed accompanying increase in engine speed, the ignition position is gradually delayed as the engine speed is increased.
