Abstract: A thermoplastic polyimide having good processing characteristics, obtainable by polymerizing an acid component and a diamine component, wherein an aromatic tetracarboxylic acid dianhydride represented by formula (I): or its derivative is used at least as a part of the acid component.

Abstract: A distributed portal system 20 is used for designing and managing the creation and management of website content pages at two or more sites and comprises a main Web server 21 and one or more part execution servers 22, 23. The main Web server is connected to the part execution servers by the Internet and comprises a content management system for managing a content page by dividing the content page into an arbitrary plurality of areas, disposing content separately in each of the areas, and managing the content that is disposed in the areas by separating the content into a plurality of blocks and disposing HTML text or parts in each of the blocks. The part execution server comprises a part database for storing parts, and has functions for entering and retrieving required parts from the part database in response to external requests and for executing parts.

Abstract: The present invention provides a heat-generating agent or singlet oxygen-generating agent effective as a new cancer treatment agent which, unlike an anticancer agent based on an alkylating agent such as MMC, uses the action of heat and/or singlet oxygen to kill cancer cells and reduce the burden on patients. A heat- and/or singlet oxygen-generating agent or a cancer treatment agent, comprising an organic peroxide such as the peroxide of an imidazole derivative or a chemiluminescent compound such as a dioxetane compound.

Abstract: An object of the invention is to provide a casting nozzle in which attachment and deposition of alumina or the like can be prevented while a drift of molten steel can be prevented. The casting nozzle according to the invention is characterized in that the casting nozzle has a molten steel flow hole portion in which “a plurality of independent protrusion portions and/or concave portions” are disposed so that each of the protrusion portions and/or concave portions has a size satisfying the expression (1): H?2 mm and the expression (2): L>2×H mm [in which “H” shows the maximum height of the protrusion portion or the maximum depth of the concave portion, and “L” shows the maximum length of a base portion of the protrusion portion or concave portion].

Abstract: Disclosed is a method for preparing oxy-diphthalic anhydrides, which comprises reacting a halo-phthalic anhydride represented by the formula (1): where Hal represents F, Cl, Br or I, with a carbonate salt selected from the group consisting of lithium carbonate, sodium carbonate, magnesium carbonate and calcium carbonate in a solvent to prepare oxy-diphthalic anhydrides represented by the formula (2):

Abstract: The present invention belongs to the field of techniques related to a laser robot and a method of controlling the same, particularly for performing weaving of a laser beam easily with high accuracy without the provision of a vibrating condenser lens at the leading edge of an arm.To solve the problems, in the laser robot (RB) of the present invention, a first inclined mirror (41a) is mounted on a motor (42a) inclined at a predetermined angle from a plane perpendicular to the direction of the rotation axis of a rotor shaft. Similarly, a second inclined mirror (41b) is mounted on a motor (42b) inclined at a predetermined angle. The laser beam (LB) emitted from a laser oscillator (8) is reflected in series by the first and second inclined mirrors (41a, 41b) and is subsequently propagated in the laser robot (RB) to be directed toward workpieces from the tip of a torch (7).

Abstract: A golf club comprises a tubular member folded back from the middle thereof toward the interior thereof, an outer wall part as providing an outer shape of a golf club head, and an inner wall part integrally formed with the outer wall part at the folded portion which portion is formed on the back surface part of the golf club head, the tip of the inner wall being integrally provided with the tip of the club shaft. The golf club can be set very deeply in the center of gravity thereof since impact energy can be transmitted through the club shaft to a grip end. Said golf club can be greatly made light-weight owing to the use of the hollow tubular member for the club head.
