Dai Nippon Printing | Date: 2016-10-31

The present invention provides a substrate for suspension that includes a first structural part including a metal supporting substrate, an insulating layer, a wiring layer, and a cover layer, and a second structural part formed so as to extend continuously from the first structural part and has no metal supporting substrate. A position of an edge of an upper surface of the insulating layer coincides with a position of an edge of the lower surface of the cover layer or the position of the edge of the upper surface of the insulating layer is positioned on a side closer to the wiring layer than to the position of the edge of the lower surface of the cover layer at a boundary region between the first structural part and the second structural part.

The present invention provides a halftone mask comprising an assist pattern and a manufacturing method of the halftone mask, which uses an ArF excimer laser as an exposing source, is used for a projection exposure by an off axis illumination, does not resolve the assist pattern while keeping the focal depth magnification effect as the assist pattern, and may form a transferred image having high contrast of a main pattern. A photomask is a photomask comprising the main pattern which is transferred to a transfer-target surface by the projection exposure and the assist pattern which is formed nearby the main pattern and not transferred, characterized in that the main pattern and the assist pattern are each constituted from a semi-transparent film made of the same material, a retardation of 180 is generated between the light transmitting through the main pattern and the light transmitting through a transparent region of a transparent substrate, and a predetermined retardation within the scope of 70 to 115 is generated between the light transmitting through the assist pattern and the light transmitting through the transparent region of the transparent substrate.

A main object of the present invention is to provide a method of producing a volume hologram laminate which can regenerate a hologram image in an arbitrary wavelength by a simple process. To attain the object, the present invention provides a method of producing a volume hologram laminate using a volume hologram forming substrate which comprises: a substrate, a volume hologram layer formed on the substrate and containing a photopolymerizable material, a resin layer, formed on the substrate so as to contact to the volume hologram layer, containing a resin and a polymerizable compound, characterized in that the producing method comprises processes of: a hologram recording process to record a volume hologram to the volume hologram layer, a substance transit process of transiting the polymerizable compound to the volume hologram layer, and an after-treatment process of polymerizing the polymerizable compound.


A lead frame includes a die pad and a plurality of lead portions each including an internal terminal and an external terminal. The external terminals of the plurality of lead portions are arranged in an alternately staggered form such that the respective external terminals of a pair of lead portions adjacent to each other are alternatively located on an inside or an outside. A lead portion has an inside region located on the inside of a first external terminal, an outside region located on the outside of the first external terminal, and an external terminal region having the first external terminal. The inside region and the outside region are each formed thin by means of half etching. A maximum thickness of the outside region is larger than a maximum thickness of the inside region.


A lead frame for mounting LED elements includes a frame body region and a large number of package regions arranged in multiple rows and columns in the frame body region. The package regions each include a die pad on which an LED element is to be mounted and a lead section adjacent to the die pad, the package regions being further constructed to be interconnected via a dicing region. The die pad in one package region and the lead section in another package region upward or downward adjacent to the package region of interest are connected to each other by an inclined reinforcement piece positioned in the dicing region.

Inner and outer surfaces of a container which is filled with drink are sterilized. A sterilizer is applied to an outer surface of a container (2) by blasting the sterilizer toward the outer surface of the container from at least one nozzle for sterilizer (26a-26d) disposed so as not to intersect with a mouth portion (2a) of the container, an inner surface of the container is sterilized by heat of a hot-water supplied into the container from a nozzle for hot-water, and the sterilizer adhering to the outer surface of the container is activated with the heat transferred from the hot-water to thereby sterilize the outer surface of the container.
