Abstract: A mold device includes: an outer mold part including a first outer mold, and a second outer mold that is moved toward the first outer mold to form a molding space with the first outer mold; and an inner mold part including an inner mold that is moved between a molding position disposed in the molding space of the outer mold part and an exit position deviating from the molding space. The inner mold is configured to mold a cylinder having a hollow part extending in a first direction between the inner mold part and the outer mold part when being located in the molding position. The inner mold is formed to correspond to the cylinder to form a space allowing introduction of a resin.

Abstract: The present disclosure provides an injection molding apparatus including a first mold, a second mold configured to be relatively movable toward or away from the first mold and define a cavity for forming a molded body collectively with the first mold, a stripper provided between the first mold and the second mold and configured to separate the molded body from the first mold, a first cotter block provided on the stripper, and a second cotter block provided on the second mold, configured to be rollable relative to the first cotter block, and configured to align the second mold with the first mold collectively with the first cotter block, thereby obtaining an advantageous effect of reducing a defect rate related to the molded body and improving quality and productivity.

Abstract: An optical rearrangement device includes an optical block having a substantially hexahedral shape. The optical block includes a front face, a top face, a first side face, a bottom face, a second side face, and a back face. The top face is parallel with the bottom face. The optical block is arranged such that when an input beam is incident through the front face at a right angle thereto, the input beam is totally reflected at each of the top face, the bottom face, the first side face, and the second side face and an output beam is output through the front face or the back face at a right angle thereto.

Abstract: Maskless lithographic apparatus measuring accumulated amount of light is provided. The maskless lithographic apparatus includes a light source which emits light, a stage on which a substrate is disposed, an optical system which converts the light into a beam spot array including a plurality of columns and a plurality of rows and irradiates the beam spot array onto the stage, a slit to which the beam spot array is irradiated and which passes an nth (n is a natural number) row of the beam spot array, an optical sensor which senses the nth row of the beam spot array which has passed through the slit, and a measuring unit which measures an accumulated amount of light in the nth row of the beam spot array sensed by the optical sensor.
