Title: Tape recorder with radio receiver
Inventor: OKAMOTO KOUJIROU
IPC: H04B1/20
Filed: 1982-06-26
Abstract: PURPOSE:To eliminate harsh clicks even if a record/reproduction changeover switch of a tape recorder is operated when the level of an input signal to an AM broadcast receiving circuit is lowered by lowering a volume of the click sound than the volume of the input signal. CONSTITUTION:When a record/reproduction changeover switch is operated when the input signal to a receiving circuit 2 is set at a high level, a muting switch 15 closes just in an extremely short time during which a switch 13 is switched. Thus a joint between transistors TR 9 and TR 10 is conducted. In this case, the gain control voltage delivered from an output terminal 5 of an AGC circuit 3 becomes higher than the threshold value, e.g., 0.7V. Therefore the TR 10 conducts along with the TR 9 set nonconductive respectively. Then an audio signal is supplied to an amplifying circuit 7. At the same time, the clicks generated from the circuit 2 by the spark caused between contacts of the switch 13 when the switch 13 is switched are also supplied to the circuit 7 and delivered through a speaker together with voices. The click sounds are hardly heard since the sound volume level of the click sounds is much lower than that of the voices.

Title: Voltage control oscillator and communication unit using the oscillator
Inventor: TAMAKOSHI OSAMU
IPC: H04B1/40
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce the attenuation of a basic wave via a simple output circuit part and attenuating selectively the levels of a higher harmonic that is double or more as high as the fundamental wave by connecting the output circuit part consisting of a parallel resonance circuit of a capacitive element and an inductive element in series to the signal output terminal of an amplifier circuit part. SOLUTION: An output circuit part 11 of a voltage control oscillator 10 consists of a parallel circuit of a capacitor C3 and an inductor L1. Thus, the frequency characteristic of the signal passing through the part 11 shows the characteristic of a band elimination filter which has a large loss with the resonance frequency due to the C3 and the L1 and has the small losses with frequency levels set before and after the resonance frequency. Thereby, the resonance frequency of the part 11 is set at the frequency of a double wave of the oscillator 10. As a result, the loss is reduced with the frequency of a fundamental wave and then increased with the frequency of the double wave. Accordingly, the levels of unnecessary signals are lowered among those signals that undergone the conversion of frequency and the performance of a communication unit is improved.

Prior to filling of material powder, the Pd2O is attached to the inner surface of the metal cylinder, and it is desirable that the substance produced after supply of oxygen does not react with the sintered substance. By this method, a wire can be manufactured by practical method in which a sintered substance having high superconductivity is accommodated in a metal cylinder having substantial mechanical strength and plasticity.
