Abstract: Provided is a method for cell patterning, using an electrode substrate including a plurality of electrodes and a cell culture substrate disposed so as to face the electrode substrate, the method comprising the steps of: introducing a cell suspension containing cells into a region between the electrode substrate and the cell culture substrate; applying a voltage to the electrodes to generate a non-uniform electric field in the region; and arranging the cells at a position with low electric field strength on the cell culture substrate by utilizing negative dielectrophoresis so as to obtain the cell culture substrate on which the cells are arranged in a predetermined pattern.

Abstract: A polishing jig for mounting a working object lens on a polishing apparatus that polishes the concave surface of the working object lens, a conveyor tray for exclusive use for conveying the polishing jig, and a conveying method and a conveying apparatus for conveying the polishing jig or the like with the working object lens held thereon to a working apparatus such as the polishing apparatus. The polishing jig (1) includes a mounting potion (2) to be mounted on a chuck of a polishing apparatus, a ring-shaped closely contacting portion (3) for closely contacting with a convex surface (11) of a working object lens (10), and a filling gap portion (4) having an opening at the closely contacting portion for being filled with adhesive substance (7) which adheres to the convex surface of the working object lens closely contacted by the closely contacting portion to hold the working object lens.

Abstract: The present invention relates to a polishing jig for mounting a working object lens on a polishing apparatus that polishes the concave surface of the working object lens, a conveyor tray for exclusive use for conveying the polishing jig, and a conveying method and a conveying apparatus for conveying the polishing jig or the like with the working object lens held thereon to a working apparatus such as the polishing apparatus.

Abstract: An apparatus for continuously manufacturing a corrugated sheet having a varying fold width and also having fold lines extending either straight or in wavy or zig-zag fashion in a direction widthwise thereof. The apparatus includes upper and lower toothed rolls each made up of a group of toothed discs and having a circumferential groove defined between each neighboring toothed discs. At least one of the upper and lower toothed rolls is supported for adjustment in position relative to and in a direction towards and away from the other of the upper and lower toothed rolls. Upper and lower guide bars while extending in a direction parallel to the upper and lower toothed rolls are accommodated within the circumferential grooves for movement in a direction towards and away from each other over a distance corresponding to the height of each tooth of any one of the upper and lower toothed rolls.

Abstract: This invention involves forming a series of electronic components wherein each component has a pair of coplanar conductors extending therefrom which were formed from a metal strip and then severed therefrom after attachment of a component therebetween with at least one of said conductors having an enlarged portion of said strip remaining at its free end so that the pairs of component conductors when positioned between a pair of adhesive strips to hold the components in spaced relationship with at least said enlarged portion between the strips they will be securely retained thereby.
