Title: Estimating method for deterioration degree of covering for optical coated fiber
Inventor: TAMURA SHINJI
IPC: G01M11/00
Filed: 1991-02-08
Abstract: PURPOSE:To make it possible to estimate the deterioration degree of the covering of an optical coated fiber without destruction by applying a load on the central part of the optical coated fiber which is horizontally supported, and operating the spring constant and the modulus of longitudinal elasticity of the optical coated fiber based on the displacement and the load. CONSTITUTION:A load (f) is applied with a minute load converter 2 on the central part of an optical coated fiber 1 which is horizontally supported on a supporting stage 5. A displacement (x) is measured with a measuring device 4. A spring constant (k) of the core 1 is expressed by f=kx. Then, a modulus of longitudinal elasticity (Young's modulus) E is obtained based on the constant (k). The deterioration degree of the covering of the coated fiber 1 is estimated by the Young's modulus E based on the load (f) applied with the converter 2 and the displacement (x) when the load (f) is applied. In this way, the spring constant (k) is measured and the Young's modulus E is operated. Thus, the deterioration degree of the covering of the coated fiber 1 can be readily estimated by the Young's modulus E based on the load (f) and the displacement (x).

Title: Magnetic resonance method with reduced motion artifact
Inventor: PEETAA BERUNERUTO
IPC: G01R33/567
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To establish a magnetic resonance method which can generate good compromise between the picture quality and inspection time. SOLUTION: By a magnetic resonance method concerned in which the motion artifact is reduced, the displacement of a pulsating object in the inspection zone, or part of the object, with respect to the reference position is measured continuously, and the reproduction of a magnetic resonance image is made using only the magnetic resonance signals obtained from the inspection zone while the displacement from the reference position lies under the threshold. In this process of gating, a phase encoding inclination (ky ) acting on the inspection zone by differing time integral is generated before acquisition of a magnetic resonance signal, and the threshold (vs ) is improved by changing depending upon the associate phase coding inclination (ky ).

Title: Wire cut electric discharge machine
Inventor: MAGARA TAKUJI
IPC: B23H7/02
Filed: 1987-02-23
Abstract: PURPOSE:To improve accuracy of machining in a corner part, by equipping a machine with a discriminator, which discriminates a machining speed for whether or not it reaches a predetermined value, and a control unit which controls the machining speed to be locked to the predetermined value by a signal from said discriminator. CONSTITUTION:In finish machining, a discriminator 12 generates a signal when a cutting amount decreases in an out-corner part or the like with a machining speed reaching a predetermined value. Here the predetermined value of the machining speed is optionally preset. A control unit 13, by the signal of the discriminator 12, controls the machining speed, when it reaches the predetermined value, to be locked so that the machining speed is prevented from increasing to the predetermined value or more. The cutting amount is started again increasing when the out-corner is finished, and the machining speed, if it begins decreasing to the predetermined value or less, is simultaneously released from being locked and reset to an ordinary interpole servo. In this way, a machine, which promptly decreases the machining speed even in the linear machining immediately after change of direction because the machining speed is locked to the proper value in an edged part, generates no overshoot and no undercut.

IPC: C09K3/10
Filed: 1984-03-01
Abstract: PURPOSE:To improve the sealing properties and increase the sealing life of a gasket by using sheets having low compressive modulus for layers on the both sides of sealing faces and laminating a sheet having high compressive modulus internally. CONSTITUTION:Sheets 2, 4 having a low compressive modulus are used for the layers on the both sides in the laminating direction of a gasket 1, while a sheet 3 having a higher compressive modulus is used inside the gasket 1. Since sheets of high porosity are used for the layers on the both sides of the gasket 1, these sheets drape sufficiently over any scratch on a sealing face, to secure a sealing performance, while the sheet having low porosity and high compressive modulus, which is inserted inside, also prevents gas from leaking.
