  • 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: 11558575
    Abstract: An analog-to-digital converter includes a generator, a comparator, and a counter. The generator generates a reference signal whose voltage changes with respect to time. The voltage of the reference signal changes with a constant slope in a predetermined first period since the voltage starts changing. The slope of the voltage becomes steeper with respect to time in a second period after the first period. The comparator compares the reference signal and a voltage output from outside, and outputs a comparison result. The counter counts at a predetermined first cycle since the voltage of the reference signal starts changing until the comparison result is inverted.
