When used in a medium wave receiver, in order to receive medium wave broadcasting, it is necessary to tune the band from 520kHz to 1610kHz.With a conventional air variable condenser, it is necessary to tune the entire band in a series. With the frequency linear type, this is not possible due to insufficient capacitance change, and with other types, the frequency dial scale is wide at low frequencies and narrow at high frequencies, making it difficult to tune. This invention was made to solve the above-mentioned drawbacks, and its configuration can be explained with reference to the drawings. From the position, the amount of change in capacitance at the beginning of rotation is made rapid and the change in reception frequency is increased, and as the rotation angle increases, the amount of change in capacitance is made gentler and the change in reception frequency is also reduced.

In this way, the changes in the rotation angle of the rotating electrode and the changes in the frequency scale on the frequency dial can be made proportional to each other using a simple structure, and the dial scales in the low and high ranges of the receiving frequency can be made equal. This makes it easy to receive medium wave broadcasts over the entire band.

Book 1, Title of the Invention Air Variable Capacitor 2, Claims (a) - side () of the fixed electrode (1) of the air variable capacitor
8) Make a curve. (b) The negative side of the rotating electrode (2) of the air variable capacitor (
Make 5) a curved line. Air variable condenser configured as above. 8. Detailed Description of the Invention This invention provides a fixed electrode (
- side (3) of 1) and - of rotating electrode (2)
By curving and changing the shape of the side (5), the capacitance changes from the state where the rotating electrode (2) is in maximum contact with the fixed electrode (1) as the rotating electrode (2) rotates. This is to match the inclination to the purpose of use.Explaining when used in a medium wave receiver, to receive medium wave broadcasting, the frequency range is 520 kHz to 1610 kHz).
It is necessary to tune the band up to lz. With conventional air frequency capacitors, it is not possible to tune the entire band in a series, but the frequency linear type is unable to do so because the amount of change in capacitance is insufficient, and with other types, the frequency dial cannot be tuned at low frequencies. The scale was wide, and the frequency dial scale was narrow at high frequencies, making it difficult to tune. This invention was made to solve the above-mentioned drawbacks, and its configuration is explained with reference to the drawings.The rotating electrode (2)
From the position of maximum capacitance where the electrode is in maximum contact with the fixed electrode (1), the amount of change in capacitance at the beginning of rotation is increased, the change in receiving frequency is increased, and the amount of change in capacitance is decreased as the rotation angle increases. Make it looser and lessen the change in reception frequency. In this way, the change in the rotation angle of the rotating electrode and the change in the frequency scale on the frequency diagram μ are made proportional to each other using a simple structure, and the dial scales in the low and high ranges of the receiving frequency are made equal. This makes it easy to receive medium wave broadcasting over the entire band. 4. Brief description of the drawings The front view (1) of the present invention shows that the fixed electrode (2) is the rotating electrode (3), and the rotating electrode (3) is fixed. The part (4
