摘要： A capacitor has a capacitor element, an electrolyte, a cylindrical case made of metal and having a bottom, a metal terminal plate, and a sealing rubber. The terminal plate has a body portion and a flange portion projected from an outer peripheral surface of the body portion toward the case. The sealing rubber is abutted onto the flange portion of the terminal plate, and is interposed between the outer peripheral surface of the body portion of the terminal plate and a side surface of the case for sealing the case. The case has a drawn and grooved portion formed by being drawn and thus grooved from an outside of the side surface at a place so that the sealing rubber is compressed between the outer peripheral surface of the body portion of the terminal plate and the case. Then, a ring-like groove is provided on the outer peripheral surface of the body portion of the terminal plate at a portion, which is padded with the sealing rubber, the sealing rubber is projected into the groove.

摘要： A cross-differential amplifier is provided. The cross-differential amplifier includes an inductor connected to a direct current power source at a first terminal. A first and second switch, such as transistors, are connected to the inductor at a second terminal. A first and second amplifier are connected at their supply terminals to the first and second switch. The first and second switches are operated to commutate the inductor between the amplifiers so as to provide an amplified signal while limiting the ripple voltage on the inductor and thus limiting the maximum voltage imposed across the amplifiers and switches.

摘要： A method for determining probability that prostate cancer will metastasize, as well as a diagnostic reagent used therefor is disclosed. It was discovered that the percentage that NF-κB-p65/RelA has the 254th amino acid threonine which is phosphorylated is significantly higher in the prostate cancer cells in the cases where the bone metastasis was observed than in the cases where bone metastasis was not observed. Thus, the method for determining probability that prostate cancer will metastasize comprises measuring human NF-κB-p65/RelA in which 254th amino acid threonine is phosphorylated, which human NF-κB-p65/RelA is contained in a prostate tissue separated from human.

摘要： An architecture for detecting amplifier power is provided. The architecture includes a voltage envelope detector that receives a voltage signal and generates a voltage envelope signal. A current envelope detector receives a current signal and generates a current envelope signal. A power amplifier level controller receives the greater of the voltage envelope signal and the current envelope signal, such as by connecting the output of the voltage envelope detector and the current envelope detector at a common point and conducting the high frequency current components to ground via a capacitor. A power amplifier level control signal is then generated based on the voltage drop across the capacitor.
