Filed: 1988-08-12
Abstract: PURPOSE:To improve the bonding strength of a dielectric resonator and the work performance of the assembling process by mounting the dielectric resonator to the inner face at the side of an oscillated case at which a penetrating body is penetrated in a microwave oscillator whose oscillated frequency is adjustable. CONSTITUTION:The dielectric resonator 1 with a support base 2 is bonded to the upper bottom face being an inner face of the oscillator case 7 at which a screw 5 is penetrated.

Title: Mean n-th power device and amplitude compressing/ extending device using the same
Inventor: AMANO YASUHIRO
IPC: G01R19/00
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To smooth the switching of a gain, and to clearly change the switching by using a mean N-th power means for a method for synthesizing a control signal. SOLUTION: Rectified currents |I6| of input currents inputted to a signal synthesizer 100 are compared with currents I8 from a current source, and when the input currents are smaller, an output voltage V2 is turned into a constant gain area in proportion to the size of an input voltage V1, and set by the currents I8. On the other hand, when the input currents are larger, the output voltage V2 is turned into a constant voltage output area for outputting a constant voltage regardless of the size of the input voltage V1.  Thus, the switching of the gain of a output voltage characteristic from the constant gain area to the constant voltage output area can be clearly changed by control currents I3 obtained by N-power averaging and synthesizing the inputs of the rectified currents |I6| being an input signal inputted to the signal synthesizer 100 and the currents I8 of the current source.
