Abstract: There are provided a photosensitive resin composition which can be applied to either a projection exposure or direct-write exposure machine without fine adjustment of the composition, and can form a resist pattern having an excellent cross-sectional shape in which an undercut in which the bottom portion of the resist pattern is hollowed and omission of the top of the resist pattern are less likely to occur, and a line width of an intermediate portion (central portion) and a deepest portion (bottom portion) in the depth direction of the cross section of the resist pattern is less likely to be larger than a line width of the surface portion (that is, linearity in the depth direction of the resist pattern contour is favorable), and which has excellent insulation reliability and crack resistance reliability, and a dry film using the same, a printed wiring board, and a printed wiring board manufacturing method.

Abstract: A mold-clamping device for a blow molding machine. The device includes a body and tie bars which move forwardly and backwardly while supported in a horizontal posture by the body. It also includes front and rear platens which are disposed on the front and rear end portions of the tie bars. A movable platen which is forwardly and backwardly movable is also disposed on the tie bars in such a manner as to face the front platen. Split mold halves are disposed on opposite sides of the front platen and the movable platen. The body portion is provided with a crank mechanism and a driving source so that the driving force transmits a driving force to a crank shaft of the crank mechanism. The rear platen and the movable platen are connected to a crank arm of the crank mechanism through connecting rods.

Abstract: An in-mold label applying device for applying a label to an interior of a metal mold for blow molding includes an entering arm composed of a first link portion having a changeable configuration, an applying arm composed of a second link portion having a changeable configuration and also having a shaft in common with the entering arm on a distal end thereof, and a label fitting portion provided on a distal end of the applying arm. When the entering arm advances toward the metal mold while changing in configuration, the applying arm also changes in configuration and is operatively associated with the changing configuration of the entering arm. When the configuration of the applying arm changes, the applying arm causes the label fitting portion to move to a prescribed position within the metal mold.
