Abstract: An indicating instrument dial plate includes a substrate that is formed in a plate shape, made of a transparent or semi-transparent material, has a front face including a hairline-treated surface and has a rear face which is irradiated with a dial plate illumination light from a light source inside an indicating instrument, and a half-mirror layer that is formed in a shape of a thin film covering the hairline-treated surface by sputtering and adapted to allow a portion of external light incident to the front face of the substrate from the outside of the indicating instrument to be transmitted into the substrate and to allow a portion of the external light to be reflected. The hairline-treated surface is made by forming fine line-shaped grooves on the front face of the substrate. The hairline-treated surface includes hairline-patterned unevenness which diffuses the external light.

Abstract: An inexpensive variable inductor has inductance value continuously changeable without reducing a Q value. When a control voltage is applied to a control terminal of a MOS transistor from a power supply, a continuity region is formed in a channel, and a region between main terminals becomes conductive. When the control voltage is changed, length of the continuity region in the channel is changed. This changes length of a path area of an induced current, flowing in an induced current film. Thus, the amount of induced current is increased or decreased. Therefore, when the control voltage of the MOS transistor is changed, the inductance value of the coil is continuously changed.
