| 20080231197 | POWER SUPPLY UNIT, HIGH-FREQUENCY CIRCUIT SYSTEM AND HEATER VOLTAGE CONTROL METHOD - At the time of restoration of the power supply after a power failure, a voltage higher than that in the normal operation mode is supplied to a heater. After a lapse of a predetermined time, the voltage to be supplied to the heater is switched into the voltage in the normal operation mode while a control signal for stating the operation of an electron tube is output. Alternatively, at the time of power activation, the rate of change of current flowing through a heater is determined for every period of time. When the rate of change becomes equal to or lower than a predetermined threshold, a voltage higher than that in the normal operation mode is supplied to the heater, and after a lapse of a predetermined time, the voltage to be supplied to the heater is switched into the voltage in the normal operation mode while a control signal for stating the operation of the electron tube is output. | 09-25-2008 |
| 20090009086 | TRAVELING WAVE TUBE - A bottom portion of a metal tape is attached to an end portion of a helix. A coaxial inner conductor for input or output of a high frequency signal is fixed by its end portion being interposed between upright surfaces of the metal tape. The metal tape is joined to the coaxial inner conductor by being laser-welded to opposite side surfaces of the coaxial inner conductor. | 01-08-2009 |
