The result of computation shows exactly a temperature coefficient in the part of the sensors 120 and 121 within the sphere of a temperature control. By using this temperature coefficient thereafter, temperature compensation is conducted for the detection outputs of the sensors 120 and 121 on the basis of an output of the sensor 132 for detection of temperature. By this constitution, excellent measurement of a temperature characteristic can be executed.

By ionimplanting, e. g. Si, in the whole surface, the polycrystalline Si film 3 is turned into an amorphous state. One example of Si ion implantation condition is as follows; dosage is 1X10<15>cm<-2>, and energy is 40keV. After that, e. g. in a nitrogen (N2) atmosphere, heat treatment is performed at a low temperature of, e.g. about 700 deg.C for about 20 hours. By this heat treatment, the amorphous Si film formed by turning the ion-implanted polycrystalline Si film 3 into an amorphous state is subjected to solid-phase growth, and as the result, the polycrystalline Si film 3 whose crystal grain diameter is 0.5-10mum is formed.

Abstract: PURPOSE:To improve the temperature characteristics of a tuner of double-super system, by constituting a band pass filter and a local oscillator with use of a microstrip resonator and without using an abbreviated microstrip line. CONSTITUTION:A narrow band pass filter (BPF) which is shown in the diagram comprises a line pattern includng an input line 18, an output line 19 and a resonator 20 equivalent to 1/2 wavelength respectively on a substrate.
