Patent JP-2001084932-A (JP)
Title: Hot cathode of x-ray tube and manufacturing method thereof
Inventor: OSAKA NAOHISA
IPC: H01J9/04
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a thermionic emitter to be any shape and prevent it from falling off by forming a recessed part to a heating element, filling powder of thermionic emitting material inside the recessed part, and sintering and securing it. SOLUTION: A heating element 10 is made of glassy carbon. The glassy carbon is of large electrical resistance and can heat thermionic emitting material to sufficient temperature without having to make an exciting path (without complicating the shape) long, and accuracy of finishing is high, since an edge can be processed sharply when a groove 22 is processed. The groove 22 is formed on an upper surface of an emitter supporting part 20 of the heating element 10, and powder of lanthanum hexaboride as the termionic emitting material is filled inside the groove 22. The heating element 10 is then mounted to an open-type X-ray tube and excited while exhausting the inside of the tube to form a vacuum. Voltage to be applied is gradually increased to slow a temperature rise. Gas exhaust of the filled powder is thereby performed first, and the powder is simultaneously sintered.

Abstract: PURPOSE:To obtain an inexpensive optical multiplexing and demultiplexing device with good diffraction efficiency by providing a holographic diffraction grating where 0.6<lambda/d<1.9 holds for wavelength lambda in use and a diffraction grating (d). CONSTITUTION:Light beams of lambda1-lambda5 emitted from an optical fiber 1 pass through a lens 7 to become parallel light, which is made incident on a holographic plane diffraction grating 8; and the light beams are dispersed and reflected by the wavelengths through the grating 8, passed through the lens 7 again, and made incident on projection optical fibers 2-6.

The grating 8 is easily formed by exposing photoresist to two pieces of luminous flux with a single wavelength and developing the photoresist, and a replica formed by transfer has the characteristics of the original grating 8 as they are. For the purpose, the replica is formed to easily mass-produce gratings having the same characteristics.

Title: Detecting device for folded corner of paper sheet
Inventor: SASAKI TOMOYUKI
IPC: G01B21/08
Filed: 1990-09-29
Abstract: PURPOSE:To detect a folded corner, distinguishing from a patched tape and double-ply sheets by observing a condition of falling of a detecting roller after bouncing at the leading end of a paper sheet so as to detect a folded corner. CONSTITUTION:With an example of tape is patched to the leading and trailing end parts of a paper sheet, sampling points #1 to #21 exhibit noise caused by vibration, but the zone #22 to #53 corresponding to a part of the paper sheet which is actually engaged with thickness detecting rollers are equally divided into 8 for every of four data. However, at point #22, the leading end of the paper sheet comes to the thickness detection rollers 20A, 20B and bumps against the latter so that the bouncing of the detection rollers is relatively large. Thereafter, they drop under reaction at point #27, then rebounce at point #30 by reflection, and thereafter they again drop at point #33. Accordingly, excepting the zone from #22 to #33, only five zones are observed. As a result, since the value of the zone #50 to #53 becomes minimum, it is estimated that this value is the thickness of the paper sheet. Further, if this value is out of a predetermined range, it is regarded the double ply sheets or a patched tape is present, so that it is rejected.
