  • Publication number: 20200366009
    Abstract: A terminal 20 includes a terminal connection portion 21 connected to a counterpart terminal and a board connection portion 24 connected to a conductive path 13 of a board 11. The board connection portion 24 has a plate shape portion 25 that is a plate shape. The plate shape portion is disposed behind the terminal connection portion 21 and is soldered to the conductive path 13 of the board 11. The board connection portion has a plate-shape first projection walls 28A to 28D that are bent from edge portions of a lateral direction side of the plate shape portion 25 and that project to an opposite side to the board 11 side. The plate shape portion 25 and the first projection walls 28A to 28D have a plating layer 37 that is formed on a plate surface of the plate shape portion and the first projection walls.

  • Patent number: 10793935
    Abstract: An object of the present invention is to provide a clock screw having a deep interference film blue color that contributes to decorativeness while also having superior scratch resistance and corrosion resistance, and a method for producing the same. The means for solving provided by the present invention consists of: a clock screw comprising a screw base material made of steel containing carbon at 0.5% by weight to 1.0% by weight, an oxide layer of the steel on the screw base material having a thickness of 60 nm to 80 nm, and a fluorine coating film on the oxide layer; and, a method for producing the clock screw comprising: a step for preparing the screw base material, a step for forming the oxide layer by heating the screw base material for 30 minutes or longer at a temperature of 300° C. or lower in an air atmosphere, and a step for forming the fluorine coating film on the oxide layer.

  • Patent number: 9503531
    Abstract: A content server (10) includes a receiving unit (14) that receives a request signal from a request source terminal, an acquisition unit (15) that acquires an IP address assigned to the request source terminal from the request signal, and a determination unit (16) that determines a location region of a user of the request source terminal by referring to an address storage unit (11) based on the acquired IP address. The address storage unit (11) stores address information including location regions of registered users set based on addresses of the registered users and IP addresses assigned to terminals of the registered users in association with each other.
