Abstract: A modular submersible repairing system includes a working unit having a tool module capable of repairing structures in a reactor. A scanning/pitching module is capable of being selectively connected to or disconnected from the tool module, and is provided with a scanning/pitching shaft for scanning or pitching the tool module. A submersible fan module is capable of being selectively connected to or disconnected from the scanning/pitching module. A first buoyant module keeps an orientation of the tool module. A base unit includes a manipulator module internally provided with an actuator driving mechanism. An adsorbing module is capable of being detachably mounted on the manipulator module and a wall. A second buoyant module keeps the orientation of the manipulator module. The scanning/pitching module and the manipulator module are provided with a submersible connecting device capable of being operated in water for engagement and disengagement.

Abstract: A modular submersible repairing system is capable of dealing with various tasks somewhat inefficiently, though, and of being inserted and installed in a reactor instantly, and highly maneuverable. A repairing method is carried out by the modular submersible repairing system.

Abstract: An oil level gauge guide device is coupled to an engine to make the operation of inserting an oil level gauge easier. The oil level gauge guide device has a guide body and a fastening portion. The guide body is generally funnel shaped and narrows gradually from a first open end toward a second open end. The fastening portion fastens the guide body to a cylinder head of main engine body in such a manner that the second open end of the guide body faces an oil level gauge insertion opening of the cylinder head into which the oil level gauge to be inserted.

Abstract: A resist material having a resist and particles mixed into the resist, a major component of the particles being a cluster of carbon atoms, is provided. A method for fabricating a resist material is also provided, the method repeatedly performing: a first step of coating a substrate with a resist film; and a second step of depositing particles whose major component is a cluster of carbon atoms on the resist film. Accordingly, a resist film with high etching resistance can be obtained, and it is possible to realize a reduction in the thickness of the resist film, improvements of contrast of resist patterns; resist sensitivity; heat resistance of resist films; mechanical strength of resist patterns; and further, stabilization of resist sensitivity. Therefore, highly precise fine pattern fabrication can be realized.

Abstract: A plurality of bowden cables extend between a pivotal mirror unit and a control device so that the mirror unit is pivotally movable in response to manipulation of the control device. A spring-biased wire guide member engages the bowden cables in a manner to constantly apply the same with substantially equal tensions to achieve assured remote control.

Abstract: A pattern to be examined is scanned to produce binary information of divisional regions of the pattern corresponding to the picture elements of respective scanning lines as parallel information. The parallel information regarding the shape and position of the pattern is concurrently examined under two modes. The second mode includes examination of the vertical edge and the horizontal edge, examination of the vertical and horizontal edges by compensating the deviation of mask setting in the horizontal direction, and examination of the vertical and horizontal edges by compensating the deviation of mask setting in the vertical direction.

Abstract: In an aqueous cold setting paint, a specific copolymer and an epoxy resin being soluble in an alcoholic sovlent are incorporated.The specific copolymer is obtained by a solution polymerization of(a) a monomer having ethylenic unsaturated double bond and a nitrogen-containing base,(b) a monomer having ethylenic unsaturated double bond and a phosphoric acid group or a salt thereof or an ester thereof,(c) a monomer having ethylenic unsaturated double bond and carboxylic acid group or a salt thereof and(d) a monomer having ethylenic unsaturated double bond which is copolymerizable with a component (a), (b) or (c) or further treatment of the resulting copolymer with a base.
