Title: Luminous flux matching device
Inventor: MASUDA SHIGEFUMI
IPC: G02B6/34
Filed: 1978-10-31
Abstract: PURPOSE:To provide the optical system which is unaffected by the wavelengths of light by providing a light emitting part and photo detecting part to a spherical reflecting mirror and placing the photo detecting part in the position where the light from the light emitting part through a reflecting mirror enters. CONSTITUTION:The light from an optical fiber LF1 being a light emitting part enters an optical fiber LF2 being a photo detecting part by way of a concave faced mirror M. The light emitting optical fiber LF1 is small in light diameter and large in light radiation angle and the photo detecting optical fiber LF2 is large in light diameter and small in light radiation angle, these being placed in the positions of l1, l2 respectively from the concave faced mirror M. The light from the light emitting optical fiber LF1 may be totally entered to the photo detecting optical fiber LF2 by adjusting the distances of l1, l2. Since the reflecting mirror M has no factors such as refractive indices as with the case of lenses, the light of different wavelengths may be matched, thus the device is usable for multiplex communication.

Abstract: PURPOSE: To secure the precision of the degree of balance of installation for a moving core by setting the effective track width of the gap of a magnetic head within the visual field of a microscope and separating the observation light corresponding to the gap part including both ends by an optical system and synthesizing separated lights and causing them to agree with one another.  
     CONSTITUTION: Gap 4 of a magnetic head is placed in position X under relay lens RL, and the light from light source 11 is irradiated to gap 4 through object lens OL, etc. At this time, the reflected light reaches a semitransparent prism through prism 12. When a lens of an approximately 40 scale factor is used as object lens OL, the whole of the effective track width of approximately 0.334mm can be observed in the visual field by the microscope system. The light which reached semi-transparent prism 13 is divided into light pathes I and II by prisms 13' and 13". Lights of light pathes I and II which passed through full-reflection prisms 14 and 15 are synthesized by semi-transparent prism 18 and are observed in position Y by eye lens EP. Here, lights passing through light pathes I and II are gap images including ends D' and D" of gap 4 respectively, and they can agree with each other within the effective track width above by adjusting them respectively.

Title: Rotating anode x-ray tube
Inventor: HAYASHI TADASHI
IPC: H01J35/20
Filed: 1983-07-25
Abstract: PURPOSE:To almost eliminate generation of lowering performance in a getter by sealing the flange of a cathode stem and a glass envelope, while injecting inert gas into a tube from a exhaust tube. CONSTITUTION:A metal pipe 4 previously mounted on a turning anode 2 and a metal ring 5 previously sealed in the glass envelope 1 are partially welded at a weld portion 6 so as to exhaust the gas in the tube to the outside. Next, a cathode having the getter 10 previously mounted on the stem 7 of glass is welded and sealed to the end of the glass envelope 1 at the periphery portion of the stem flange 11. At this time, the inert gas, such as Ar, is injected through the exhaust tube 12 provided in the stem 7 from the outside of a bulb. The inert gas flows out from the welded portion 6 to the outside of the bulb, after filling the inside of the glass envelope 1 and flowing by itself, and thereby the getter has no possibility to deteriorate its performance by heated air.

Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an electric shock resistant glove noticing the lowering of the dielectric breakage resistance according to the decrease of the thickness by abrasion with the change of the surface color of the glove and allowing easy and clear recognition of the exchanging timing of the glove by the user. SOLUTION: The coating thickness of the layer 2 from a glove body 1 to the outer surface of the layer is the critical thickness to endure a prescribed voltage at the inside of the glove. The color of the outer surface of the layer 2 is made to be different from the color of the layer 3 applied to the outer surface of the layer 2. The surface color of the glove becomes different between a state having a sufficiently large thickness of the electrical resistance layer to prevent the electric shock and a state having a thickness of the electrical resistance layer possible to cause the electric shock by the further abrasion. Accordingly, the critical state of the electric resistance is clearly shown by the color change to get the attention of the worker and prevent the electrical shock by sure recognition of the exchanging timing to a new glove by the worker.
