摘要： A collector core of a microwave tube has an insulator and a radiator around a cylindrical outer peripheral portion thereof. The cylindrical insulator and radiator comprise a slit along a central axis of the collector core, respectively. These slits are arranged on mutually overlapped positions. Portions of the collector core corresponding to these slits are cut off so as to be flat or concave. These slits and the flat surface or the concave portion are arranged symmetrically in a section of the collector core.

摘要： A high pressure discharge lamp includes a quartz glass bulb, a conductive element which is sealed at a sealing portion of the bulb, and a pair of electrodes. Each electrode is disposed in the quartz glass bulb so as to be opposite the other and connected to the conductive element. A part of each electrode is sealed with the quartz glass bulb at the sealing portion so as to generate a contacting portion formed by the part of each electrode and the bulb. The maximum length, Lmax, of the contacting portion is defined as: Lmax (mm)null200/(PnullD); and the minimum length, Lmin, of the contacting portion is defined as: Lmin (mm)null0.8/(D2nullnull) or Lmin (mm)null0.7 whichever is longer, where D is the diameter (mm) of the electrode and P is the power (W) supplied to the electrode.

摘要： A high pressure discharge lamp includes a quartz glass bulb having a sealing portion; and a pair of electrodes. Each electrode of the pair of electrodes is disposed so as to be opposite the other in the quartz glass bulb. The quartz glass bulb of the high pressure discharge lamp contains at least mercury and a halogen gas. The partial pressure of oxygen (O) in the quartz glass bulb is about 2.5null10null3 Pa or less and the partial pressure of the halogen gas in the quartz glass bulb is in the range between about 1null10null8 nullmol/mm3 and 1null10null7 nullmol/mm3.

摘要： An electron gun also has a cathode for emitting electrons, a heater cap which contains a heater for applying the cathode with thermal energy for emitting electrons, a retainer for securing the cathode on the heater cap by clamping the peripheral edge of the cathode onto the heater cap, and a cylindrical Wehnelt supporter. The cylindrical Wehnelt supporter has a Wehnelt electrode for focusing an electron beam that is formed in such a shape that an average angle of the surface thereof with respect to an outermost shell of the electron beam matches a Pierce angle, and three or more heater cap supporters for securely supporting the heater cap at a position at which an electron emitting surface of the cathode and an opening formed through the wehnelt electrode satisfy a predetermined perveance.
