  • Patent number: 11964446
    Abstract: A continuous production system continuously produces a product from a raw material powder. The system includes a first processor that performs a first process on the raw material powder, a second processor that performs a second process on the powder on which the first process has been performed by the first processor, and a test chamber through which the powder being sent from the first processor to the second processor passes. A cleaner blows gas from an inlet side opening formed in the inner face of a channel connected to the test chamber from the first processor on the downstream side of an inlet side gate valve for opening and closing the channel toward a direction to form a swirling flow along the inner face of the channel.

  • Patent number: 11944590
    Abstract: A continuous manufacturing system continuously manufactures a product from a powder of a raw material. The system includes a first processing device that performs first processing on the powder of the raw material; a second processing device that performs second processing on the powder on which the first processing device has performed the first processing; and an inspection and sorting device including an inspection chamber into which powder sent from the first processing device flows. When a prescribed amount of the powder has accumulated in the inspection chamber, the inspection and sorting device inspects the powder inside the inspection chamber after blocking a path connecting the first processing device to the inspection chamber. When the inspection ends, the inspection and sorting device removes the blocking after discharging the powder from inside the inspection chamber.

  • Patent number: 8551281
    Abstract: When laminating two types of film (1, 2) with different melting points on the two sides of a metal sheet (3), the thickness of the low melting point side film (2) is adjusted. Specifically, the thickness d2 of the low melting point side film (2) at the part sandwiched between the lamination roll (10) and metal sheet (3) is made a range defined by d2?k(?MP??T)/V. Here, ?MP is the difference of melting points of the two types of film, k is k?2, 0<?T=MP1??Ti?50(° C.) (Ti is the metal sheet temperature at the inlet side of the rolls, V is the sheet running speed, ? is a constant determined by the heat removal conditions at the time of lamination, where 0.75??<1). Due to this, sticking of the low melting point side film (2) to the lamination roll (10) can be prevented.
