  • Patent number: 11217798
    Abstract: A hot press device presses one or more objects to be pressed at a predetermined temperature, and includes: a roller around which a roll on which the objects to be pressed are disposed at predetermined intervals is wound; hot plates which are disposed to face one surface of the objects to be pressed while corresponding to the roll supplied from the roller; press units which are disposed to push the hot plates on the objects to be pressed; and a pitch changing unit which moves the hot plates in a direction in which the roll is moved or in a direction opposite to a direction in which the roll is moved, in accordance with a distance between the objects to be pressed.
    Type: Grant
    Filed: October 2, 2018

  • Patent number: 10351875
    Abstract: A method for producing a transgenic plant which has increased content of 20-hydroxyecdysone compared to a wild type plant includes transforming a plant cell with a recombinant vector containing a gene encoding CYP85 (cytochrome P450, 85 family) protein derived from spinach (Spinacia oleracea). A method for producing a transgenic plant with enhanced insect resistance includes transformation of a plant cell with a recombinant vector containing a gene encoding CYP85 derived from Spinacia oleracea.
