Title: Connector for light guide of endoscope
Inventor: HASHIGUCHI TOSHIHIKO
IPC: A61B1/06
Filed: 1983-05-27
Abstract: PURPOSE:To make manufacture of the titled connector easier and reduce the optical transmission loss, by constituting an optical member installed to the inside of a guide tube so as to face the incident side front end part of a light guide in such a way that the optical member is held by the guide tube with an annular elastic member. CONSTITUTION:Since an optical member 28 is held in the 2nd tube body 20 by uniformly elastic-deforming O-rings 27 in the direction of diameter, the axis of the member 28 coincides with the axis of the 2nd tube body 20, even though the outer diameter dimensions of the optical member 28 are not uniform. Therefore, the axis of the member 28 also coincides with the axis of one end part of a light guide 25 held by the 1st tube body 19 and, as a result, the transmission loss of lights among them is reduced. Moreover, a connector having such constitution can be manufactured easily, because the tolerance in the outer diameter dimensions of the optical member 28 can be increased. In addition to the above, this connector is not contaminated and spoiled by an adhesive agent, since the member 28 can be held without using any adhesive agent. In this way, the connector can be manufactured easily and the optical transmission loss can be reduced.

Title: Production of martensitic stainless steel billet for seamless steel pipe
Inventor: KAWABATA HIROKI
IPC: C21D8/10
Filed: 1989-04-13
Abstract: PURPOSE:To reduce the amount of delta-ferrite and to prevent the occurrence of eruption flaw in a tube making stage by holding a steel billet before finish rolling in an austenite stabilization temp. region for a specific length of time at the time of producing the steel billet by rolling a cast billet of high Cr steel. CONSTITUTION:A cast billet of a martensitic high Cr steel containing >=8wt.% Cr is rolled into a steel billet. In the above rolling stage, the steel billet is held, prior to finish rolling, at a temp. in an austenite stabilization region for >=1hr. It is desirable to regulate the holding time to 5-15hr in consideration of the size of the steel billet in practical use. Further, in the course of the above holding, holding at a constant temp. is not necessarily required and temp. may fluctuate if it stays within the austenite stabilization region. By this method, the amount of delta-ferrite in the steel billet to be passed through a piercing stage can be reduced, by which the occurrence of eruption flaw formed in a tube making stage can be reduced.

Filed: 1985-05-02
Abstract: PURPOSE:To enable a fail-safe safety device, by arranging an emission means and a detection means for light, electromagnetic waves, ultrasonic waves and the like to face each other through the inside of a tube comprising a soft material. CONSTITUTION:While a man or an object is off a rubber tube 4, the tube 4 is stretched straight to allow the admission of light into a light-receiving element 8 from a light-emitting element 3 and an input is applied to a relay connected to the element 8 to close a relay contact, so that the contact detection signal will not be outputted. Then, when a man or an object 19 gets in contact with the tube 4 to bend or squeeze it 4 to more than a certain extent, light of the element 3 intercepted by a part of the wall surface of the tube 4and will not reach the element 8 at all or will do being reduced below a fixed level, so that the relay contact is opened to output the contact detection signal. Also when the elements 3 and 8 and the like fail to work owing to a trouble or interruption of the power source, the relay contact is opened to output the contact detection signal. Thus, the safety side output (contact detection signal) is sure to be produced when encountering an abnormality, thereby enabling a fail-safe safety device.

IPC: B21D39/02
Filed: 1994-05-06
Abstract: PURPOSE:To suppress the wear of a lower die, and to prevent the generation of a flaw, caused by the hit of work and roller by constituting the surface of a roller in contact with the guide surface of the lower die of a material softer than a material constituting the guide surface of the lower die. CONSTITUTION:At the time of a regular bending work, a second reference surface 25 is brought into contact with a first guide surface 35 of a lower die 30. Consequently, an edge part 43 is correctly pressed and the regular bending work can be performed. At that time, the part of a roller 20 in contact with the guide surfaces 35 and 36 of the lower die is constituted of a material softer than the lower die 30. The lower die 30 is, for instance made of cast iron and the parts constituting the reference surface 24 and 25 of the roller 20 are made of gun metal, tin, aluminum, etc., or resin. Therefore, when the roller 20 is rolled or slid while pushed to the guide surfaces 35 and 36 of the lower die, wear caused by friction among the roller 20 and the guide surfaces 35 and 36 of the lower die is mainly generated on the soft roller 20 side, thereby the wear of the guide surfaces 35 and 36 of the lower die is suppressed.

Title: Johannson-type analyzing crystal
Inventor: MATSUTANI MIYUKI
IPC: G21K1/06
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity to use thick crystals, enable the expansion of a solid angle and easily realize asymmetrical crystals by constituting a crystal-mounting seat having a plurality of cylindrical surfaces formed in stairs. SOLUTION: On the mounting surface of a crystal seat 1, crystal-mounting surfaces which constitute sections of a cylindrical face respectively are shaped like stairs. That is, four crystal mounting surfaces P1 , P2 , P3 and P4 are formed like stairs. Consequently, it is sufficient if only the difference in curvature radiuses of cylindrical face sections is set equal to the thickness of each crystal to be stuck on each crystal-mounting surface, so it is not required to increase the thicknesses of the crystals as they come away from the center of a spectrum, and a problem of difficulty in curvature processing does not occur. Moreover, analyzing crystals are symmetrized to the center 0 of the spectrum, but asymmetrical crystals can be made by using a part of them, and analyzing crystals having a center of a spectrum outside a crystal face can be also formed.

Title: Biaxially oriented polyester film
Inventor: INOUE TAKANARI
IPC: B29L7/00
Filed: 1988-04-18
Abstract: PURPOSE:To make slit properties favorable, by a method wherein a range of intrinsic viscosity of a biaxially oriented film mainly comprised of polyethylene terephthalate is limited and breaking strength and stress at the time of extension are made not exceeding specific ratios. CONSTITUTION:Intrinsic viscosity of 0.55-0.60 is necessary for a film, the film becomes apt to break at the time of production of the film when the viscosity is lower than 0.55 and slit property is deteriorated when the viscosity exceeds 0.60. On one hand, it is preferable that a ratio between breaking strength in a widthwise direction and stress at the time of extension is 2.20 or less, especially 2.00 or less and when the same is higher than 2.20, a cut end becomes apt to raise nap at the time of slitting. The film falling within the above-mentioned range is obtained by melting and extruding a pellet of the intrinsic viscosity of 0.65-0.56 at 275-310 deg.C. In addition, a crosswise orientation temperature is controlled so that the same falls within a longitudinal orientation temperature plus 20 deg.C or less and the intrinsic viscosity of the film is made 0.58-0.55 to make the above-mentioned ratio not exceeding 2.20. In the case where the intrinsic viscosity of the film is 0.58-0.60, the ratio can be made not exceeding 2.20 by controlled the crosswise orientation temperature so as to fall within the longitudinal orientation temperature plus 15 deg.C and heat-treating a post-orientation film at a temperature of 200-230 deg.C for at least two seconds.
