摘要： A method for controlling a semiconductor circuit, including forming an inductor and a capacitor on a substrate, which are inductively coupled to one another. The inductor has an inductance value while the capacitor has a capacitance value. The inductor and capacitor make up an oscillator circuit with two terminals. Eddy currents are generated through the capacitor when an operating current flows along the inductor. These eddy currents influence, by inductive coupling, the inductance value and performance of the oscillator circuit, thus simultaneously tuning the inductance and capacitance of the oscillator circuit.

The coil is provided with a movable contact, and the capacitor has a continuously rotating adjustment shaft, said shaft being operatively linked with said movable contact, so that the shaft is rotated at the same time as the contact of the coil is moved. Thus, during the movement of the coil contact, the capacitance of the capacitor varies up and down between a minimum value and a maximum value.

摘要： An improvement in a channel tuner assembly for a television receiver of the type including a tuner having a rotary channel selector shaft interconnected by drive train means to a channel indicator member. The improvement comprises providing yieldable means, such as a spring or the like, adjacent the drive train means to normally urge driving engagement between the indicator member and the tuner shaft, but being yieldable to permit temporary disengagement of the indicator member from the tuner shaft and movement independently thereof. With this improved arrangement, the channel indicator member can be more easily calibrated with the tuner than has previously been possible.

摘要： An apparatus for measuring torque in either a stationary or rotating shaft. Two light-polarizing screens are mounted on a shaft transmitting a torque in such a manner that the twist in the shaft caused by the torque causes a relative rotatory movement between the screens. Light from a light source passes through the screens to a light-sensing device which produces a signal according to the amount of light it receives. The relative rotatory movement of the screens caused by the applied torque causes a variation in the amount of light passing to the lightsensing device so that the signal produced indicates the amount of torque. The use of light to measure twist means an absence of drag and hence the ability to measure very small torques.
