摘要： A component is mounted onto a circuit board and is visually inspected after the circuit board is subjected to heat to determine whether the component has undergone a notable change in appearance. The component is preselected to have indicative characteristics after being subjected to heat. While the component is subjected to a predetermined temperature for less than a first duration of time, the component undergoes little or no change in appearance, and while subjected to the predetermined temperature for more than a second duration of time, the component undergoes a notable change in appearance. The circuit board is removed from a manufacturing process if the component has undergone a notable change in appearance.

摘要： An input trap circuit removes a predetermined frequency component included in an input signal and then outputs the input signal to a circuit at a later stage. The input trap circuit is provided with: a parallel oscillation circuit in which a pair of variable capacitance diodes are connected in series such that cathodes thereof are connected to each other at a junction portion and in which an inductance is connected in parallel to the variable capacitance diodes between anodes of the variable capacitance diodes at both ends thereof; a voltage applying device for applying a voltage to the junction portion so as to vary capacitance values of the variable capacitance diodes on the basis of reverse voltage characteristics of the variable capacitance diodes respectively; and a variable capacitor element connected between the junction portion and a ground.

摘要： A diversity receiver has distributors each of which is connected with each of a plurality of antennas, and as many antenna switches as there are receivers. Each of the antenna switches has as many contacts as there are distributors. The distributor distributes a radio frequency signal from the antenna into as many signal paths as there are receivers. Each of the antenna switches is connected with each of the distributors via the contact connected with the signal path. A demodulated signal selecting circuit has as many contacts as there are said receivers. The demodulated signal selecting circuit receives the demodulated output of the receivers via each of said second contacts to selectively output the demodulated outputs of the receivers.

摘要： A preset state indicating unit for use in an electronic tuning type receiver generates a visual indication when both a presetting switch and one of a plurality of channel selecting switches have been properly selected. The preset state indicating unit thus insures that tuning information pertaining to a selected station is actually stored in memory during the presetting operation done by the user.
