  • Publication number: 20210245435
    Abstract: A three dimensional manufactured product is manufactured A speed of filing an uncured light curing resin in a space for a next layer is enhanced, to improve a manufacturing speed. One surface of a container housing a light curing resin is configured by a gas-permeable sheet that faces the light curing resin, and transmits irradiation light of a light irradiating apparatus, and a light transmitting plate disposed at an outer side of the container from the gas permeable member. A pressurizing chamber controllable in pressure by a pressure controlling apparatus is defined between the gas-permeable sheet and the light transmitting plate. At moving a manufacturing stage, an inside of the pressurizing chamber is de-pressurized to cause the gas-permeable sheet to perform concave surface deformation, and at a time of performing light irradiation, gas in the pressurizing chamber is caused to permeate into the light curing resin by pressurizing.

  • Patent number: 10963602
    Abstract: An actual power generation amount receiver acquires an actual power generation amount of a photovoltaic power generation system of each time slot of each day. An extraterrestrial solar radiation calculator calculates an extraterrestrial solar radiation of each time slot of each day at a disposition position. A weather information receiver acquires an actual weather record of each time slot of each day and a weather forecast of a prediction target time slot. A similar date extractor classifies a time slot, which is the same as a prediction target time slot of each day in a search range in which an actual power generation amount is acquired, as a similar time slot for each actual weather record type. A prediction formula deriver derives a power generation amount prediction formula for calculating a predicted power generation amount based on an actual power generation amount.
