IPC: H04B1/18
Filed: 1981-10-19
Abstract: PURPOSE:To prevent unnecessary power consumption by deciding on whether the electric field intensity of a tuning frequency received signal is greater than that of the reception band of an antenna or not through an antenna amplifier, and controlling the passing band of a filter. CONSTITUTION:The hot wire 2 in the rear windshield glass 1 of a motor car is used as an antenna 8 and a radio wave received by it is inputted to the filter 14, narrow-band BPF16, and electric field intensity detecting circuit 18 of an antenna loop 24. When a radio receiver 12 selects a frequency f0, the center frequency of the BPF16 is set to the frequency f0 by a signal (a), and a comparison 19 of electric field intensity between the entire reception bands detected by an electric field intensity detecting circuit 17 for the frequency f0 and the circuit 18 is made. If the electric field intensity at the f0 is small, the filter 14 is set to a narrow band centering the f0 as its center frequency by the signal (a) through a switch 21, and its output is amplified by an amplifier 15 and inputted to the receiver 12. When the electric field intensity of the BPF16 is high and found to be greater than a prescribed value 23 through comparison 22, a signal (b) is  outputted to perform control so that the output of the filter 14 is inputted to the amplifier 15 as it is. Therefore, when the electric field intensity at f0 is large, the amplifier 15 is not in operation, thereby reducing the power consumption.

Title: Magnet driving circuit
Inventor: YANAGIDA SHIYOUJI
IPC: H01F7/18
Filed: 1982-09-27
Abstract: PURPOSE:To supply a magnet with constant energy, by a method wherein constant-current driving circuit is added by circuit means to perform negative feedback of magnet driving source voltage with respect to the magnet constant current value. CONSTITUTION:Voltage value V of magnetic driving power source is fed back to constant-current circuit through a resistor R11, for example, thereby control is performed to vary the constant current value IM depending on variation of the source voltage V. If the source voltage V varies, rising time of the magnet current varies and also energy W does. In this state, the constant current value IM is varied by value in which the variation of W is just corrected. That is, resistance value of the resistor R11 is set to suitable value and the power source for magnet driving is subjected to negative feedback with respect to the constant current value, thereby energy variation caused by variation of the rising time of the magnet current during variation of the source voltage is completely corrected.

Title: Noise eliminating circuit
Inventor: UCHIDA KAZUYUKI
IPC: H03K19/00
Filed: 1988-07-06
Abstract: PURPOSE:To eliminate noise by setting the circuit threshold value of a first logic circuit higher, and that of a second logic circuit lower. CONSTITUTION:The circuit threshold value of an inverter 11 is set higher than that of an inverter 12. Here, when a voltage of low level is applied on an input terminal (a), the inverters 11 and 12 are inverted, and respective output goes to a high level, and an output terminal (b) to a low level. By increasing the input voltage of the input terminal (a), the inverter 12 with a low circuit threshold value is inverted, and output (b) holds the low level. Next, when an input voltage goes higher than a higher circuit threshold value, the inverter 11 is inverted, then, the output (b) goes to a high level. Thus, the circuit threshold value of input observing from the output (b) becomes almost equal to the circuit threshold value of the inverter 11. Similarly, by applying a voltage of high level on the input terminal (a), it is possible to set the circuit threshold value of the input observing from the output (b) almost equal to the circuit threshold value of the inverter 12.
