摘要:
Provided is an ultrasound fracture detection device capable of accurately irradiating an ultrasound pulse to a target object, the device being characterized by being provided with an ultrasound wave irradiating transducer, a signal receiving transducer which receives a reflected wave of an ultrasound wave irradiated from the ultrasound wave irradiating transducer, a signal, storage unit which stores a received signal, and a display unit which displays an analysis program that analyzes a stored signal, a determination program that performs determination from the result of the analysis and/or performs determination from the stored signal, and the result of the analysis and/or the result of the determination, wherein the determination program performs the determination using that information relating to the received signal varies depending on the reflector within a living organism.

A cellulose acylate film of which the difference between the in-plane retardation at a wavelength of 630 nm and the in-plane retardation at a wavelength of 450 nm is 1 to 15 nm, and satisfying the following formula (2) both in the film traveling direction and in the direction perpendicular thereto: −0.5%≦{(L′−L0)/L0}×100≦0.5% (2), wherein L0 means the length of the film before the lapse of time of 24 hours at 60° C. and 90% RH; and L′ means the length of the film after the lapse of time of 24 hours at 60° C. and 90% RH followed by humidity conditioning for 2 hours.
摘要:
In an optical connector for connecting an optical fiber to a mating object having a pair of guide members, the optical connector includes a connector body fixed to the optical fiber and an adapter removably attached to the connector body. The adapter has a positioning groove for positioning an end portion of the optical fiber and a pair of guide grooves adapted to receive the guide members, respectively.

For connecting an optical fiber having a fiber axis and an axial end portion provided with a chamfered surface having a predetermined angle with respect to the fiber axis, the optical connector includes an aligning member and a holding plate. The aligning member has a principal surface and a side surface adjacent to the principal surface. The aligning member has a fiber-receiving groove for receiving the axial end portion of the optical fiber. The fiber-receiving groove extends along the principal surface in a predetermined direction and has end portions each opening on the side surface. The holding plate is faced to the principal surface and covers the fiber-receiving groove. The holding plate has a first slant surface beside one of end portions of the fiber-receiving groove. The first slant surface has an angle with respect to the principal surface. The first angle is determined smaller than the predetermined angle.

There is provided an optical fiber end face cleaner which is easy to carry and make preparations for use, facilitates cleaning operation, and what is more, makes it possible to positively remove or clear away attached materials from end faces of optical fibers without causing any of the removed materials to adhere to the end faces again. The optical fiber end face cleaner includes at least one elastic base formed by an elastic member having a flat surface of a predetermined size, and a predetermined thickness in a direction perpendicular to the surface. An adhesive layer is formed on a surface of the elastic base, for allowing the end faces of the optical fibers to be pressed against the adhesive layer to cause deposits on the end faces to adhere to the adhesive layer for removal.

An optical connector includes a housing including a coupling portion for coupling another optical connector and a blocking component for blocking an optical axis arranged in the coupling portion. The blocking component has a shutter plate blocking the optical axis and being pivotably supported by the housing with a pivot shaft and an elastic portion for normally biasing the shutter plate to a closed position. The shutter plate pivots between a position blocking the optical axis and a position to which the shutter plate is forced to move by the other optical connector when the other optical connector is inserted into the optical connector.
