Abstract: A print head for a line printer in which errors between print head chips and another component are reduced and ink leakage is prevented, and in which heat generated in print head chips is efficiently dissipated without making the structure of the print head complex or increasing the size of the print head. A plurality of print head chips (11) are arranged along an ink path (20) and are disposed on both sides of the ink path in a zigzag pattern. Dummy chips (21) which do not eject ink are disposed at regions between the print head chips (11) arranged along the ink path (20). In addition, an ink-path member (23) is provided, at least a part of the ink-path member (23) which includes portions adhered to the print head chips (11) being composed of a material having a high thermal conductivity, so that the ink-path member (23) also serves as heat-dissipating means which dissipates heat generated in the print head chips (11).

Abstract: Provided in the present invention are an image pickup lens and a design method thereof which can achieve miniaturization of the system and capable of remarkably improving the optical characteristic with a simple structure. By forming a second face on the image pickup surface side of a lens body into a Fresnel face and unifying a diffraction element with at least a first face on the object face side or the second face on the image pickup surface side of the lens body, it becomes possible to correct the Petzval sum and reduce the curvature of the field so that an excellent image plane can be obtained. Also, due to the color dispersion characteristic of the diffraction element, chromatic aberration can be well corrected. Thereby, the optical characteristic of the image pickup lens can be remarkably improved.

Abstract: Surfaces of the structural components of a nuclear power plant exposed to reactor water are wetted with an electroless plating solution containing an electrical insulating substance. The electrical insulating substance has a high resistivity about 105 (100000) times those of the structural components of the nuclear power plant or above. A metal film containing the electrical insulating substance is formed on the surfaces of the structural components exposed to the reactor water by wetting the surfaces of the structural components with the electroless plating solution. Thus, the electrochemical corrosion potential of the structural components is reduced regardless of whether hydrogen is injected into the reactor water.
