Abstract: PROBLEM TO BE SOLVED: To provide a photoelectric cathode, an electron tube, and a photomultiplier tube having a structure to dramatically improve the effective quantum efficiency. SOLUTION: The photoelectric cathodes 1A and 1B respectively comprise a supporting substrate 100 to transmit or block incident light, a photoelectron emitting layer 300 containing an alkaline metal and provided on the supporting substrate 100, and an underlayer 200 provided between the supporting substrate 100 and the photoelectron emitting layer 300. Particularly, the underlayer 200 contains a beryllium oxide and the thickness of the layer is controlled so that the ratio of the thickness of the priming layer 200 and is adjusted in its thickness such that a thickness ratio of the underlayer to the photoelectron emitting layer 300 falls within a specific range. This structure allows to obtain a photocathodes 1A and 1B having a dramatically-improved quantum efficiency. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PURPOSE:To considerably improve the performance of the high-sensitivity dark viewing device by embedding light sources, which successively emit plural infrared rays while turning on/off them, near the periphery of the image pickup center of an object while integrating them to a main body. CONSTITUTION:Plural infrared light emitting diodes 6, 6A and 6B are interally embedded in a main body 1, and the periphery of the image pickup center of an object 5 is successively irradiated with tuning on/off light. The timing of turning on/off the light overlaps the turn-on of the diodes 6 and 6A just for time t, and the light emission of a fluorescent plane 33 is continued without being interrupted. The infrared beams reflected from the object 5 are made incident to an objective lens 2, an image is formed, and the optical image is divided into picture elements by a fiber plate 30 and converted to an electronic image by a photocathode 31. This electronic image is converted to the optical image again on the fluorescent plane 33.

Abstract: PROBLEM TO BE SOLVED: To stabilize detection sensitivity while safely and certainly housing a sample in a photometric system.
SOLUTION: The photometric system 1 includes a shading housing 3 having a window 24, which permit the light from the sample A to pass toward the outside, formed thereto and the photomultiplier module 4 arranged in opposed relation to the window 24 to detect the light from the window 24. The housing 3 has the shading plate 26 attached along the window 24 so as to be capable of opening and closing the window 24, the door 7 attached to the housing 3 in a state that the sample A is placed so as to be made slidable toward the inside and outside of the housing 3 and a crank 27 which moves the shading plate 26 along the window 24 corresponding to the movement of the door 7 to the inside of the housing 3 so as to open the window 24 and moves the shading plate 26 along the window 24 corresponding to the movement of the door 7 to the outside of the housing 3 so as to close the window 24.

Abstract: PROBLEM TO BE SOLVED: To provide an electron tube socket for easily and surely fixing a cable to a casing, and to provide a method of manufacturing the same. SOLUTION: In the electron tube socket 1, the cable 2 is inserted through a through-hole 11 of the casing 8 and a through-hole 16 of a cable holding part 13; and an opening portion 11a of the through-hole 11 and an opening portion 16a of the through-hole 16 are partially overlapped with each other to be narrower than the width of the cable 2 in a predetermined direction A. The cable 2 is therefore held between a bottom part 9 of the casing 8 and the cable holding part 13. Thus, the electron tube socket 1 allows easy and sure fixing of the cable 2 to the casing 8.
