A first radiation member 165 includes radiation conductors 166 and 167, an arm 168 and a lower connection piece 169 all integrally formed by blanking. A stub 170 is likewise integrally formed on radiation conductor 166. A second radiation member 171 includes radiation conductors 172 and 173, an arm 174 and a lower connection piece 175 all integrally formed by blanking. A stub 176 is likewise integrally formed on radiation conductor 173. A first loop comprised of radiation conductors 167 and 172, arms 168 and 174 and lower connection pieces 169 and 175 exhibits capacitive impedance at a wavelength for use. The overall length of a second loop comprised of radiation conductors 166 and 173, arms 168 and 174 and lower connection pieces 169 and 175 is set equal to that of the first loop. The second loop, however, exhibits inductive impedance at the wavelength for use by adjustment of the length of stubs 170 and 176. Adjusting stubs 170 and 176 enable control of a phase of a current flowing through the second loop.

There is provided a one-dimensional MIM array having MIM structures arranged on an insulative substrate in a lateral direction and each used as a unit for storing a signal charge, for sequentially storing and transferring the signal charges between the adjacent MIM structures. With the above element structure, the signal charge is transferred in each of the MIM structures in a thickness direction (depth direction) thereof and stored in a capacitor. The signal charge stored in the capacitor is sequentially transferred in a lateral direction or to the next MIM structure. In order to drive the above charge transfer device, transfer pulses applied to a plurality of MIM structures constituting a one-dimensional MIM array are controlled to sequentially transfer and store the signal charges into the MIM structures starting from the MIM structure which is provided on the output terminal side of the one-dimensional MIM array. At the time of reading out the signal charge, signal charges are sequentially read out and transferred from the MIM structures starting from the MIM structure which is provided on the output terminal side.

A television receiver having a signal input terminal supplied with an interlace video signal and a signal coverter connected to the input terminal for converting the interlace video signal to a non-interlace signal to be displayed. The signal converter includes a signal inserting circuit for inserting new line signals between two successive line signals of the interlace signal, the new line signals being formed by interpolating one of the preceding and succeeding line signals in the interlace signal. A three dimensional filter is connected to the signal converter for attentuating vertical and horizontal high frequency components in the non-interlace video signal only when the non-interlace signal includes both of the vertical and horizontal high frequency components.

In an existing disconnection detection circuit for a bridge circuit, consideration is not taken into the fact that an offset voltage or temperature characteristic of a bridge output is degraded. Provided is a disconnection detection circuit for a bridge circuit capable of suppressing a change in a characteristic of a sensor to a minimal extent. A disconnection detection circuit 8a for a bridge circuit in accordance with the present invention comprises conducting means 9 and 10 each of which causes a current to flow from an output terminal of the bridge circuit to a predetermined potential, potential difference detecting means 12 and 13 each of which detects a potential difference between the potential at the output terminal of the bridge circuit and the predetermined potential, and a disconnection detecting means 14 that detects a disconnection on the basis of the outputs of the potential difference detecting means.
