摘要： A linear electron beam tube such as an IOT includes an input cavity (6) formed from an inner body portion (12) and an outer body (13) which are joined together by a generally cylindrical electrical insulator (14). The input cavity (6) surrounds an electron gun (1) and permits electrical connection to be made to the cathode (2) and grid (3) via parts of the inner body portion (20 and 21). The construction enables high voltage parts of the arrangement to be insulated from the low voltage outer body portion whilst presenting a low leakage path for r.f. energy within the cavity (6).

摘要： PROBLEM TO BE SOLVED: To multiply charges without the need for optimizing the parameter of a CCD structure or the structure. SOLUTION: Charges are stored in pixels of an image area 2 in the CCD imager 1 that represent intensity of an incident radiant ray and transferred to a storage section 3 and then transferred to an output register 4 on the basis of every row by applying a proper drive pulse to electrodes 7, 8. Signal charges in the output register 4 are transferred up to a multiplier register 5 with a drive pulse applied to charges 9, 10 to provide charge transfer in a direction denoted by the arrow. A single or pluralities of drive pulses fed to charges in the multiplier register 5 have an amplitude sufficiently high to generate a high electric field area in the register element enough to cause signal multiplication with collision by ionization. Thus, low noise amplification of the signal charges is obtained and the multiplied signal charges are detected by a charge detection circuit 6.

摘要： PURPOSE: To resolve problems caused by the application of a high voltage to a cathode and a grid by keeping an inner body part at high voltage to an outer body part, and forming no conductive connection between both body parts. CONSTITUTION: Direct electrical contact does not exist between any part of an inner body part 40 and flanges 44, 46, and an insulating dielectric material 52 is molded between them. Thereby, the outer body part 42 is insulated from very high voltage applied to the inner body part 40 during use. The piled up region of both body parts 40, 42 shows very high impedance to direct current, and the low voltage (ground) of the outer body part 42 is made possible. Very low impedance to high frequency is realized, and leakage of high frequency component from a cavity is obstructed.

摘要： PURPOSE: To symmetries a part in close vicinity to an interactive space of an anode structure, and obtain excellent performance by making the outside ends of respective anode vanes exist at almost same outside radial distance from the center of a circle, making its insides exist at almost same inside radial distance, and arranging them at equal intervals along the circle with this inside radial distance as a radius. CONSTITUTION: An anode structure 2 forms two sets of resonant cavities arranged around a cathode 1, and one sets 5 of resonant cavities have the large volume, and are alternately arranged with the other sets 6 of cavities. The outside ends 7 of vanes 4 are inserted into a slot of a cylindrical wall 3, and are arranged on the circumference having a radius (a) from the center of the cathode 1, and the inside ends 8 of the respective vanes 4 are also respectively arranged at the same distance (b) from the center of the cathode 1, and are arranged at almost equal distance along the circumference of a radius (b). In this way, since the inside ends of the respective vanes are symmetrically arranged to an interactive space, excellent performance of a magnetron is obtained. Since dimensionally different both cavities become almost the same in a radial directional depth, an anode structure as a whole is reduced in the size.

摘要： PROBLEM TO BE SOLVED: To provide large heat radiating capacity for anode blades, and reduce the possibility of generating arc discharge in the magnetron shortening the service life of a magnetron by reducing an anode blade recessed part into which an output probe is inserted. SOLUTION: A magnetron 1 is composed of a cathode, an anode, an output probe 5 or the like. The anode is composed of a cylindrical main body 2 put in the coaxial relationship with the cathode and plural anode blades 3 and 4 installed around the inner periphery of the cylindrical main body 2 by mutually placing an interval. The output probe 5 is composed of a conductive sleeve 7 and a conductive rod 6 installed in the concentric relationship in the sleeve 7. This output probe 5 is arranged in a bored hole of a magnetron casing 10 and the cylindrical main body 2 of the anode, and is inserted through an opening 9 communicated with a recessed part 11 notched in a single anode blade 3. This recessed part 11 is fairly smaller than a recessed part necessary so far. The output probe 5 separates from the blade 3, and does not physically contact it.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive electron beam tube. SOLUTION: This electron beam tube includes a single metal cylinder 11 and a plurality of wall parts 12-19 in the transverse direction, which are installed in the cylinder 11 and partition resonant cavities 20, 21, 22 in the cylinder 11. Since the cylinder 11 is made as being integral, only the terminal part of the structure body requires the vacuum-jointing part. The drift spaces between neighboring resonant cavities are surrounded in with drift tubes 27, 28, 29. The inner diameter of the cylinder 11 is changed is steps, and the assembling work of the structure is made easy and precise. At the time of use, electron beam is directed in the longitudinal direction of the X-X axis and mutually affected by applied radio frequency energy to amplify the radio frequency signals.

摘要： PURPOSE: To provide a shield of high level for preventing the emission of the electromagnetic radiation by surrounding an output prove by a shield structure, and locating the same in a magnetic field of a Faraday cage having a vacuum vessel and a pair of polarities. CONSTITUTION: A cylindrical anode block having a resonance cavity, a coil 8 and the like of a vacuum vessel of a magnetron, is mounted in an internal cavity 2 of the vacuum vessel. A long pin 9 of an output prove is surrounded by a sleeve 23 forming a shield structure 15, and the first and second tubes 16, 17 which are separated from each other, to prevent the electromagnetic radiation from a pin 5. Further the vacuum vessel is installed between a pair of magnetic poles of a Faraday cage of a sealed metallic container, and the electromagnetic radiation is shielded through the vacuum vessel. Thereby the magnetron having the shield of high level, which can prevent the emission of the electromagnetic radiation, can be obtained.

摘要： PURPOSE: To prevent an electron beam from turning back along a klystron by generating magnetic fields in an area between resonant cavities and collectors and changing the amplitude of this magnetic field together with a distance in the path direction of the electron beam. CONSTITUTION: The klystron includes an electron beam generating segment 1, an interaction segment 2 and a collector segment 3. The collector 11 operates in a suppression mode. The electron beam is generated in a cathode 4 surrounded by focusing electrodes 5, transmitted to the segment 2 via modulating electrodes 6, and a high-frequency signal to be amplified is combined with the resonant cavities 7 to 10 in the segment 2. A magnetic field is generated in the area between the cavities 7 to 10 and the collector 11 by permanent magnets 12. Then, since the circular collector 11 is surrounded by the magnets 12 coaxially, these magnets 12 generate a periodic magnetic field in the direction of the segment 3. Thus, secondary electrons generated by the collision of high- energy electrons in the beam are dissipated in the generated magnetic field, and it is prevented to turn back along the klystron.
