Abstract: PURPOSE:To obtain superior earthquake-proof effect for a wide range of vibration from a microvibration generated by traffic vibration to a middle or a large scale of earthquake vibration b composing energy absorbing members provided inside load supporting members of lead bodies and visco-elastic members arranged at least on one end of upper and lower end parts. CONSTITUTION:When a horizontal displacement is exerted upon an earthquake- proof forting device 1 by an earthquake, shearing deformation is generated in load supporting members 1A by displacement thereof. Next, shearing deformation s transmitted to visco-elastic bodies 10 and lead bodies 9 that are energy absorbing parts 1B for the earthquake-proof supporting device 1. At this time, if the earthquake scale is very small, the horizontal displacement is small, transmission of the shearing deformation to a column member 7 is very slight, the visco-elasticity bodies 10 are deformed to absorb almost all thereof, and transmission thereof to the upper structure takes place very slightly. Meanwhile, when the earthquake scale is large, the horizontal displacement is large displacement quantity is transmitted to the lead bodies 9 as well via the visco-elastic bodies 10. At this time, the lead bodies 9 inserted into holes 5 are plastically deformed to absorb earthquake energy, and generates earthquake-proof effect.

Title: Double refraction measuring apparatus
Inventor: SAKAI KIYOKAZU
IPC: G01N21/23
Filed: 1992-02-29
Abstract: PURPOSE:To simplify the measurement by making a sample holding stage on a holding board rotatable by a motor or the like, and making the holding board inclinable by a motor or the like about a line along the surface of a holding plate as a central shaft, thereby performing measurements while the rotating angle and the inclining angle of a sample are changed. CONSTITUTION:A sample S is set on a sample holding stage, and a motor 5 is started to turn a polarizer 1 and an analyzer 2. A data processing device 11 starts to take in the outputs of an optical sensor 10 when a photoelectric detector 6 detects a reflecting body at a side face of a holding disk of the polarizer 1, with rotating the polarizer 1 and analyzer 2 once. The retardation of the sample S is calculated and stored from the maximal and minimal values of the outputs during this time. After finishing the measurement, the motor is driven to rotate the holding stage, e.g. by 10 deg.. The same measurement is repeatedly carried out. Moreover, the holding stage is inclined, for example, by 5 deg. by a motor 29, and the same measurement is repeated. When the difference between the maximal and minimal values is small, a 1/4 wave plate 15 is inserted into an optical path and the measurement is conducted again. Accordingly, the retardation is obtained from these measurements and the measurement is automated.

Abstract: PROBLEM TO BE SOLVED: To reduce the sliding resistance of a groove part and a convex part and to prevent the damage of the groove part by forming the groove part of a fixing roller coming into contact with the projecting part of a driving gear by cutting/bending. SOLUTION: The fixing device is constituted in such a manner that a groove part expansion preventing member 12 for preventing the enlargement of the groove width of a cut/bent part 1b caused by the driving force of the driving gear 5, is attached to the cut/bent part 1b of the convex part engaging part of the groove part 1a of the fixing roller 1 engaged with the convex part 5a of the driving gear 5. At this time, the convex part 5a of the driving gear 5 presses the edge on a driven side of the groove part 1a of the fixing roller 1 by the rotation of the driving gear 5, so that even if a load is applied to the groove part 1a of the fixing roller 1, in a direction where its groove width is enlarged, the enlargement of the groove width of the groove part 1a is prevented by the groove width expansion preventing member 12.  Thus, a stress concentration on the root part of the groove part 1a of the fixing roller 1 is prevented and the occurrence of a crack in the root part of the groove part 1a is eliminated.
