Abstract: A metal mold for manufacturing a honeycomb structure having a plurality of cell density regions and an annular boundary wall includes a honeycomb-like slit part, which is opened to an extrusion surface of a single metal mold body, that is formed of a plurality of cell slits for forming the plurality of cell density regions and an annular boundary slit for forming the boundary wall. Out of the plurality of cell slits, adjacent cell slits adjacent to the boundary slit have all corner portions formed in a round shape by the adjacent cell slits and the boundary slit.

Abstract: A sealant resin composition for retort packaging film comprises a high density polyethylene as the main resin component and a linear low density polyethylene polymerized by use of the metallocene catalyst. A sealant film produced therefrom is resistant to whitening, heat fusion, heat deformation after being subjected to boiling sterilization treatment and prevent breakage of pouches produced therefrom even at low temperatures because of its high impact strength and heat sealing strength.

Abstract: An image recording apparatus of this invention includes a microfilm feeder for moving images on a microfilm to a read position; a printer section for forming an image on the microfilm located at the read position on a sheet; a plurality of bin trays for stacking the sheets delivered from the printer section; a sorter for distributing the sheets delivered from the printer section to the bin trays; a case mark detector for detecting a case mark formed in correspondence with a specific one of images of each case on the microfilm; and a CPU for controlling the sorter in accordance with an output from the case mark detector so that different bin trays hold the sheets, on which images of each objective case are formed, in units of cases; and an input unit for inputting a copy set number. The CPU also controls the printer section so as to repeat an operation for sequentially recording the images of each objective case in a predetermined order in units of sets.
