摘要:
A grinding wheel having a circular outer periphery, and a working front end face for grinding a roll as installed in place on a rolling mill or other equipment, such that the front end face is held in pressed frictionally sliding contact with an outer circumferential surface of the roll. The wheel has an annular first abrasive member, and one or two annular second abrasive member(s) which is/are formed integrally with the first abrasive member, and disposed on corresponding at least one of the radially outward and inward sides of the first abrasive member. Each second abrasive member comprises a bonding agent different from that of the first abrasive member, and has a lower modulus of elasticity than the first abrasive member. Also disclosed is a grinding wheel which has a single abrasive body whose outer and/or inner circumferential surface(s) is/are tapered such that the radial wall thickness decreases in an axial direction toward the working end face. The abrasive body may preferably contain short glass, carbon or alumina fibers.

A multi-layer bonding method of the present invention includes: forming a first bonded substrate by bonding a first substrate and an intermediate substrate in a bonding chamber; conveying a second substrate inside said bonding chamber when said first bonded substrate is arranged inside said bonding chamber; and forming a second bonded substrate by bonding said first bonded substrate and said second substrate in said bonding chamber. According to such a multi-layer bonding method, the upper-side substrate can be bonded with an intermediate substrate and then a first bonded substrate is bonded with a lower-side substrate without taking out the first bonded substrate from the bonding chamber. For this reason, a second bonded substrate can be produced at high speed and at a low cost.

A device is provided with: a first substrate mainly containing silicon dioxide; a second substrate mainly containing silicon, compound semiconductor, silicon dioxide or fluoride; and a bonding functional intermediate layer arranged between the first substrate and the second substrate. The first substrate is bonded to the second substrate thorough room temperature bonding in which a sputtered first surface of the first substrate is contacted with a sputtered second surface of the second substrate via the bonding functional intermediate layer. Here, the material of the bonding functional intermediate layer is selected from among optically transparent materials which are oxide, fluoride, or nitride, the materials being different from the main component of the first substrate and different from the main component of the second substrate.

A room temperature bonding method of the present invention includes a step of activating two substrates to prepare two activated substrates; a step of bonding the two activated substrates to produce a bonding resultant substrate; a step of performing annealing of the bonding resultant substrate to reduce residual stress of the bonding resultant substrate. According to such a room temperature bonding method, the residual stress of the bonding resultant substrate can be reduced and the quality can be improved.

A system for endoscope data management of an endoscopic image of a body acquired by an endoscope is provided. An image filing apparatus retrieves the image from the endoscope, and records data of the image and scope ID assigned to the endoscope in association with one another. A washer washes the endoscope. A memory is incorporated in the washer, for storing log information of washing of the endoscope. A data manager retrieves the log information on line with the washer, to record the scope ID and the log information in association with one another. A server device records the data of the image, the scope ID and the log information on line with the image filing apparatus and the data manager. Furthermore, the data manager includes an editor for editing the log information of the washer.
摘要:
A method of room-temperature bonding a plurality of substrates via an intermediate member, includes: forming the intermediate member on a surface to be bonded of the substrate by physically sputtering a plurality of targets; and activating the surface to be bonded by an ion beam. In this case, it is preferable that the target composed of a plurality of types of materials is physically sputtered. Since the materials of the intermediate member are sputtered from the plurality of targets arranged in various directions from the surface to be bonded of the substrate, the intermediate member can be uniformly formed on the surface to be bonded. Further, since the intermediate member is composed of the plurality of types of materials, the room-temperature bonding of substrates difficult to bond together when an intermediate member is composed of a single type of material can be performed without heating and excessively pressing the substrates during bonding.
摘要:
A content search and display system capable of increasing opportunities for a user to encounter more unknown contents than ever. Operating situation detecting device detects an operating situation of search condition specifying device. According to the operating situation of the search condition specifying device, condition adding/modifying device adds or modifies a search condition. In the course of searching, opportunities are produced for the user to encounter unexpected unknown contents not randomly, but based on a certain search condition, by operating the search condition specifying device.
