摘要:
The present invention provides a photosensitive resin composition capable of forming an insulating film, which is superior in both a roughening property and an adhesiveness, and a via-hole, which is highly reliable in connection, and a multilayer printed circuit board. The present invention provides a photosensitive resin composition containing a first resin, which is an epoxy resin, and a second resin having a N-substituted carbamic acid ester atomic group and a radical polymeric unsaturated bond in its side chain. The second resin is desirably an oligomer having a repeating unit expressed by the following general formula (chem. 1) or (chem. 3) by 3-10 units. Where, X is H or CH3, Y and Z is H or an alkyl group of carbon number 1-4, n is 0 or 1, a part of R1 is an atomic group expressed by the following general formula (chem. 2), the residual R1 is a hydroxyl group, and R2 is an alkylene group of carbon number 1-4.

A stencil printer includes a rotary printing drum around which the stencil master is wrapped, a main motor which rotates the printing drum, a press roller which is rotatable in parallel to the printing drum in contact with the printing drum, and a pair of opposed conveyor rollers which feed a printing paper between the printing drum and the press roller. A conveyor roller motor is provided separately from the main motor and drives the conveyor rollers. A printing drum rotation detector detects rotation of the printing drum on the basis of the reference position, and a conveyor roller rotation detector detects rotation of at least one of the conveyor rollers. A conveyor roller controller controls, when the leading end of the printing paper reaches vicinity of the contact line of the printing drum and the press roller, the conveyor roller motor to drive the conveyor rollers at a target rotating speed which is lower than the rotating speed of the printing drum detected by the printing drum rotation detector and is set so that the difference between the actual rotating speed of the conveyor roller detected by the conveyor roller rotation detector and the target rotating speed is kept substantially constant.

An image signal obtained by an image pickup device is inputted to a signal processing apparatus. A frame rate of the input image signal is changed and a changing operation is controlled in the signal processing apparatus. With such a construction, a frame rate upon recording of the image signal can be changed in accordance with an application of the image. By providing a function such as a changing operation of the frame rate or the like for the signal processing apparatus side, a size and costs of the image pickup device are minimized, while an expansion of the function and a change in performance in which the recording and reproduction of an image are set to fundamental operations can be easily performed.

In a transuranium elements transmuting reactor core in which a reactor is charged with a plurality of fuel assemblies at a core and an amount of a transuranium element to be added is controlled so as to prevent a fuel element contained in the fuel assemblies from melting, the amount of the transuranium elements to be added to the fuel element is controlled so as to keep an excess reactivity of the reactor substantially zero through an operation of the reactor. A charging density of minor actinides is set to lessen outwards of a core central portion in a core area where a plutonium content is made even. The charging density of minor actinides is set high accordingly in an area where a plutonium is enriched high at the core of a plutonium enriched area where a plutonium content varies. A transuranium elements transmuting fuel pin is formed by charging a transuranium fuel material in a fuel clad and the transuranium fuel material includes at least one of fuel materials consisting of an enriched uranium and an uranium-plutonium mixed fuel and a fertile material consisting of a natural uranium and a depleted uranium contain transuranium elements.
