IPC: G01T1/32
Filed: 1985-09-27
Abstract: PURPOSE:To attain the miniaturization and cost reduction of the titled detector, by accelerating the secondary electron from a specimen while collecting the same to irradiate a crystal and detecting the diffracted electron beam from the crystal to obtain an image signal. CONSTITUTION:A tungsten monocrystal 1 is heated by supplying a current thereto to obtain a clean surface. A secondary electron 11 discharged from a specimen 10 by primary electron beam 9 is collected by a draw-out lens constituted of electrodes 7, 8 and accelerated to 85eV to irradiate the monocrystal 1. The electron beam reflected from the mirror surface of the monocrystal 1 is accelerated to 10keV to irradiate the fluorescence body 3 applied to the end surface of an optical guide 4. At this time, an interrupting mesh 2 having potential +10V to the specimen 10 is arranged between the tungsten monocrystal 1 and an optical guide 4 to interrupt a non-elastic scattered electron generating the loss of energy of 10V or more. The light from the fluorescent body 3 is guided to a photomultiplier 5 by the optical guide 4 to be converted to an electric signal and displayed on CRT6 as an image signal.

Title: Minute x-ray source
Inventor: MUROTA MASAO
IPC: H01J37/252
Filed: 1989-08-18
Abstract: PURPOSE:To improve luminance of an x-ray generating part by forming a minute hole which pierces a first electron scattering and thermally diffusing layer and reaches an x-ray generating layer and radiating an electron beam to the hole for exciting the x-ray. CONSTITUTION:Accelerated electrons at several 10keV-100keV concentrated narrow by an objective lens are radiated to an x-ray generating layer 13 which is a bottom part of a pin holes or a V-shaped groove 16 having different depth. A spherical x-ray generating part 9 is thus provided. When electron beam 6 is radiated in a multilayer using a multilayered pin hole or a V-shaped groove 16 having different depth, reflection electrons are closed and do not come out and thus the x-ray generating part 9 becomes spherical and excessive x-ray is generated at a part 17 as compared with a conventional one. As a result, without altering the apparent size of the x-ray generating part 9, the luminance of the x-ray generating part 9 is improved by the luminance intensity at the part 17.

Title: Optical space decoding method
Inventor: HASHIMOTO HITOSHI
IPC: G06E1/00
Filed: 1989-08-18
Abstract: PURPOSE:To remove the light in unnecessary positions and to allow the constitution of arbitrary decoding patterns by installing a mask corresponding to the decoding position in the final stage at the time of spacial decoding. CONSTITUTION:Only the light existing in the spacially separated position corre sponding to a logical computation is selected from incident light by a kernel 1-4. A quarter-wave plate 1-5 circularly polarizes linearly polarized light and a birefringent plate 1-6 advances the linerly polarized light component in a horizontal direction rectlinearly and moves the linerly polarized light component in a perpendicular direction to different routes. A quarter-wave plate 1-7 polarizes the linearly polarized light in the horizontal/perpendicular directions to clockwise/counterclockwise circularly polarized light. A birefringent plate 1-8 moves the linearly polarized light component in the horizontal direction. Finally, the decoded light 1-15 is outputted through the mask 1-9. The mask 1-9 allows the transmission of the light only in one grating among four and shuts off the rest. The appearance of the light in the unnecessary positions is obviated in this way and the constitution of the arbitrary decoding patterns is attained by the combination of the elements for adjusting the polarized light and the birefringent plates, etc.

Title: Inverter
Inventor: ARAYA KEIJI
IPC: H02M7/537
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To eliminate a separate resonance inductor, and attain reduction in the number of parts mounted and manufacturing cost, by magnetically- combining a secondary coil with a primary coil and a tertiary coil through a parallel connection of the primary coil and a serial connection of the tertiary coil and a resonant capacitor, in a resonant circuit part. SOLUTION: Gate voltage is applied to the gate of a transistor 4 through a starting resistor 14, connected with a node 3a of an inputting power source part 100 for turning on the transistor 4. Electromotive force is then generated in a tertiary coil 8 by the induced voltage of a primary coil 6. At the same time, the added amount of the primary coil 6 and the tertiary coil 8 is distributed in parallel to a resonant capacitor 9 as a resonant voltage. On the other hand, when the starting voltage of the tertiary coil 8 exceeds Zener voltage of a Zener diode 17, the transistor 4 turns off. The transistor 4 conducts the on and off operations, and resonant operation is continued. As a result, an induced voltage is generated in a secondary coil 7, through the electromagnetic conversion of the primary coil 6 by this operation.
