  • Patent number: 10170346
    Abstract: A lower mold has a bottom surface member and a side surface member. An upper end surface of the bottom surface member forms an inner bottom surface of a cavity and has a planar shape corresponding to an unusual planar shape of a sealing resin. A substrate is disposed on a mold surface of an upper mold such that a component to be sealed attached to the substrate faces downward, and the cavity is filled with a fluid resin. The upper mold and the lower mold are clamped, and the component is immersed in the fluid resin. The bottom surface member is raised, and the fluid resin is pressed at a prescribed resin pressure and cured to form the sealing resin. The bottom surface member and the side surface member are moved relatively, and thereby, a molded product is released from a mold surface of the lower mold.

  • Patent number: 9913502
    Abstract: A glove base and glove are provided, which release moisture outside from the entire glove when the glove is configured only of a fiber glove base or when a coating is provided to a surface of the glove base. The glove base of the present invention is made of fibers and has a hand shape. Water-absorbing properties of a first fiber type exposed mainly to an inside surface of the glove base are higher than water-absorbing properties of a second fiber type exposed mainly to outside surface of the glove base. The first fiber type absorbs and moves moisture on a surface of a hand inside the glove base toward the second fiber type, and the second fiber type then moves the moisture from the first fiber type mainly in a surface direction of the glove base.

    Abstract: The present invention provides a method for producing a resin-encapsulated electronic component, capable of simply and efficiently producing a resin-encapsulated electronic component having both of a via electrode(s) (bump(s)) and a plate-like member. The method includes a resin-encapsulation step of encapsulating at least one electronic component in a resin. A produced resin-encapsulated electronic component includes: a substrate; the at least one electronic component; the resin; a plate-like member; and at least one bump. A wiring pattern is formed on the substrate. In the resin-encapsulation step, between a bump-formed surface in a bump-formed plate-like member obtained by forming the at least one bump in the plate-like member and a wiring pattern-formed surface in the substrate, the at least one electronic component is encapsulated in the resin, and the at least one bump is caused to be in contact with the wiring pattern.

  • Patent number: 9595483
    Abstract: A cutting device includes: an imaging module for capturing first marks and third marks, to produce primary image data; and a control module for aligning, by a conveyance mechanism, a cutting jig and an object to be cut that is placed on the cutting jig. The control module compares first positional information including positional information of a specific first mark stored or first positional information with third positional information to calculate a primary displacement amount showing a relative positional displacement between a plurality of cutting grooves and the plurality of third marks, respectively. The conveyance mechanism picks up the object from the cutting jig, and the conveyance mechanism and the cutting jig are moved relative to each other based on the primary displacement amount, to move the object by the primary displacement amount to a primary target position. The cutting mechanism cuts the object along a plurality of cutting lines.
