Abstract: A cutting tip having a three-layer laminated structure is provided. The tip is made from a disc-shaped three-layer laminate wherein a second layer consisting of a hard sintered compact of CBN or diamond is sandwiched by a first layer and a third layer consisting of a tool material such as cemented carbide. Prismatic blanks of rectangular cross-section are cut out by cutting the three-layer laminate in strips. Semi-completed tips of a desired shape are obtained by cutting up the prismatic blanks. Desired cutting edges are formed on the semi-completed tips to produce completed tips. Because prismatic blanks are obtained from a three-layer laminate and semi-completed tips are cut out from the prismatic blanks like this, the semi-completed tips can be obtained in large numbers, yield is high, and the manufacturing cost of the tip can be reduced.

Abstract: In a device for processing data signals, a storing part stores an input signal and the data signals included in the input signal are extracted from the storing part and the data signals are output at a desired output speed. Then, the data signal is output based on storage information of the input signal.

Abstract: A diol compound, for example, hexanediol, is produced with a high efficiency by esterifying a carboxylic acid mixture, collected from a reaction product mixture of a liquid phase oxidation of cyclohexane, with an esterifying agent and hydrogenate-decomposing the resultant esterification product mixture with hydrogen.

Abstract: A tripod-integrated camera is provided with a camera body assembly for housing a camera and a tripod body assembly for housing a tripod, the tripod body assembly is detachably attached to the camera body assembly in such a manner so as to form an elongated, substantially integral structure.
