Title: Band switching device for an stereo receiver
Inventor: MURAKAMI SHINICHI
IPC: H04H1/00
Filed: 1985-11-14
Abstract: PURPOSE:To improve an option characteristic by making the function of the 2nd filter inoperable only when an Am stereo demodulator circuit selects a stereo state and receives a stereo signal. CONSTITUTION:An iF filter 6 is constituted of a serial connection between the 1st filter 15 composed of a wide band and the 2nd filter 16 composed of a narrow band. If a mode changeover switch 9 is turned ON, an AM stereo demodulator circuit 8 takes a monaural state, envelope-detects an inputted iF signal, demodulates it in a monaural state, and supplies a signal L+R to subsequent stages, whereby the iF signal passes through the 2nd filter 16 with a narrow band. On the other hand, if the mode changeover switch 9 is turned OFF, the AM stereo demodulator circuit 8 attains a stereo state, and the envelope and phase of the inputted iF signal are detected. Thus in a stereo reception state, the high frequency of an audio output is expanded to enjoy music with affluent stereo feelings, while in a monaural reception state an audio output can be received at an S/N similar to a conventional monaural reception.

Title: Pressure-welding type semiconductor device
Inventor: SAITO KATSUAKI
IPC: H01L21/52
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of the unevenness of pressing stresses from pressing electrodes by a method wherein the pressing electrodes are respectively provided with two regions or more, the first regions of the regions are formed as the vicinities of the outlines of the shapes of the electrodes coming into contact with electrode films, the second regions and succeeding regions are formed as the regions other than the first regions and the yield stresses of the first regions are set larger than those of the second regions and succeeding regions. SOLUTION: A semiconductor substrate comes into contact thermally and electrically with buffer electrode plates 116 and 117. The plates 116 and 117 are pressed by pressing units and the like, which are provided on the outside of a semiconductor element, through pressing electrodes 118 and 119 and 21 reduction in the contact resistance between the electrode plates 116 and 117 is contrived. The electrodes 118 and 119 in this case consist of two materials, the first materials 125 respectively form the vicinities of the shapes of the outlines of the electrodes 118 and 119 and the second materials 126 respectively form sites other than the vicinities of the shapes of the outlines of the electrodes 118 and 119. The yield stress of the materials 125 is about 1.2 times larger than the yield stress of the materials 126.  By applying an even pressing force to the thyristor, an even heat dissipation within the surfaces of the substrate and the even electrical contact within the surfaces of the substrate can be contrived and a reduction in pressing stresses from the electrodes 118 and 119 that a semiconductor device results in being broken due to an insufficient pressing to the substrate can be prevented.
