摘要： A microwave absorber composed of dense silicon carbide having an electrical resistivity of one ohm-centimeter or more. In an electron linear accelerator, it is necessary to provide a microwave absorber to absorb excess energy used to accelerate electrons and discharge this excess energy in the form of heat in order for the accelerator to operate safely. The important characteristics are high-frequency wave absorption, good heat resistance, good thermal conductivity, and stability in a vacuum. The invention meets these requirements with a microwave absorber composed of dense silicon carbide. In an electron linear accelerator the absorber is attached to the end portion of an accelerator guide or a branch portion of a power divider to absorb unnecessary wave energy. Such a microwave absorber is found to have characteristics rendering it highly suitable for this application as well as others.

摘要： The present invention provides a space-saving and low-cost emergency power system, which can be installed on a narrow place having limited space and employs a battery that is long in service life and low in frequency of replacement. This emergency power system comprises a circuit having a DC load, a rectifier, and a battery, which are electrically connected to one another. This circuit is adapted so that normally, DC power is supplied from the rectifier to the DC load, and the battery is charged, and that in an emergency, such as a power failure, in which an outage of the rectifier occurs, electric power is automatically supplied from the battery to the DC load. In this system, a sodium sulfur battery is employed as the battery.
