Abstract: The present invention relates a combination drug for treating a renal cancer and a potentiator for therapeutic effects of a tyrosine kinase inhibitor. The combination drug includes a combination of a tyrosine kinase inhibitor, and a dipeptidyl peptidase-4 inhibitor. The potentiator includes a dipeptidyl peptidase-4 inhibitor. The potentiator enhances therapeutic effects of a tyrosine kinase inhibitor on a renal cancer.

Abstract: When first high frequency signals from an antenna input terminal are selected to be outputted, all transistors constituting first and second switch devices are turned off and a RF modulator is also turned off. Therefore, first high frequency signals are transmitted to a TV output terminal through a first transmission line. When second high frequency signals outputted from the RF modulator are selected to be outputted, the RF modulator is turned on and transistors constituting the first and second switch devices are turned on. Consequently, second high frequency signals are transmitted to the TV output terminal through a second transmission line. On this occasion, the transistors constituting the first switch grounds the first transmission line and form a parallel resonance circuit in the first transmission line.

Abstract: An improved resonator assembly employed in a capacitive pick-up assembly for use in a video disc system includes an oscillator and a resonator. The improved resonator comprises an electrode provided on a stylus for reading information carried on a disc as a track of the disc relatively moves past the stylus, a tuned line having a first end accommodated in a resonator cavity and a second end connected to the stylus electrode, a capacitive element connected between the first end of the tuned line and an inner face of the resonator cavity, and a bypass circuit connected between the tuned line and inner face of the resonator cavity. The bypass circuit has a high impedance with respect to a high frequency signal produced from the oscillator, whereby the bypass circuit cuts current flow of high a.c. component, but allows current flow of d.c. component.
