摘要:
An IC device contactor for electrically connecting IC devices each having a large number of spherical electrodes on one side of a substrate to an IC tester head for a test of electrical properties or characteristics. The IC device contactor includes: a socket board having a predetermined number of contact points formed on a surface thereof; an anisotropic conductive sheet having a multitude of fine conductive wires embedded in the insulating sheet in an angularly oriented state; a tip holder perforated with a predetermined number of apertures; and a predetermined number of contact tips fitted in the apertures of the tip holder for contact with the spherical electrodes of the IC devices. The anisotropic conductive sheet is disposed with its side in engagement with the socket board and the other side in engagement with the contact tips to electrically connect the contact tips with the contact points on the socket board. The contact tips are assembled with the tip holder in such a way as to be securely retained in position within the respective aperture and are brought into pressed contact with the anisotropic conductive sheet at one end while the other end of the contact tips is projected out of the aperture by a predetermined length.

A medium cassette includes a slidable cassette pull-out part and is capable of being lengthened and shortened, and a medium tray has a first pull-out part slidably provided to a tray base, the medium tray can be lengthened and shortened, and the medium tray is detachably provided to the top of the medium cassette. The cassette pull-out part is provided with a first engaging protrusion and a second engaging protrusion which engage with the tray base, and inclined surfaces are formed on both sides in the detachment direction of these engaging protrusions. The designs of these inclined surfaces, of the heights of the protrusions, and of other features make it possible to perform the operations of lengthening/shortening and installing/detaching the medium cassette and the medium tray separately from the other component's side without restriction, even while the medium cassette and the medium tray are engaged together.

A first shaft member extends in a first direction. A second shaft member extends in the first direction. A carriage body is disposed between the first shaft member and the second shaft member. A first slider comes in contact with a circumferential part of the first shaft member to allow the carriage body to slide on the first shaft member in the first direction. A second slider comes in contact with a circumferential part of the second shaft member to allow the carriage body to slide on the second shaft member in the first direction.

An object of the present invention is to provide a water-borne urethane resin composition for forming a microporous layer, which is suited for use in a fibrous material substrate, especially an artificial leather, and which has well-defined heat-sensitive coagulation properties and is capable of being uniformly filled into a fibrous material substrate without causing migration, forming a micrporous layer after drying and imparting a feel equivalent to that obtained in a solvent-based urethane resin composition, i.e., an elastic and genuine feel, by impregnating or coating the fibrous material substrate with the water-borne urethane resin composition; a method of producing a fibrous sheet-like composite using the water-borne urethane resin composition; and an artificial leather obtained by the method. The water-borne urethane resin composition of the present invention comprises (1) a water-borne urethane resin having a heat-sensitive coagulation temperature of 40 to 90° C. and (2) an associated type thickener. In the method of producing a fibrous sheet-like composite according to the present invention, (i) a fibrous material substrate is impregnated or coated with (ii) the water-borne resin composition and then (iii) heat-sensitive coagulation is performed using steam.
摘要:
A method for producing an isocyanate group-blocked liquid urethane prepolymer which comprises: reacting a lactone-modified diol (3) with a polyfunctional isocyanate (4) to form an isocyanate group-having urethane prepolymer (5), wherein said lactone-modified diol (3) is obtainable by ring-opening addition polymerization of a lactone monomer (2) with a diol (1) selected from the group consisting of a polyalkylene ether diol, a polyester diol and a polycarbonate diol; and then reacting said urethane prepolymer with a blocking agent (6).
摘要:
A dental probe that directly measures pH level and temperature of gum pockets and other diseased parts of the oral cavity is provided. The dental probe has a handle and a needle with a pH sensor and a temperature sensor in the needle tip. The handle permits the dentist to manipulate the needle tip to examine a diseased spot in the mouth, where both pH levels and temperature can be analyzed. The rear part of the handle has a light receptor which remains outside the oral cavity when the needle tip is inserted in the diseased part, creating a path for light through the needle part. The dental probe is attached to a dental diagnosis device that enables processing and readout of pH levels and temperature.
摘要:
This protocol data generator-analyzer encodes and decodes protocol data units, which are transfer syntaxes used in data communications, for setting of or reference to the values as components of the protocol data units. First, table generation means generates, from an abstract syntax described according to an international standard specification as input data, a machine-processible table showing the data structure of the abstract syntax. For encoding of a protocol data unit, component data input means inputs the values of protocol data unit components. List generation/reference means generates a list having values corresponding to the data structure of the abstract syntax based on the values input by the component data input means during encoding, and converts the values to those referable using the list during decoding. Protocol data unit encoding/decoding means encodes sending protocol data units by inputting the table and list or decodes received protocol data units based on the table for list generation. Component data reference means refers to the values converted by the list generation/reference means based on the list generated by decoding of received protocol data units.
