  • Patent number: 10416597
    Abstract: An image forming apparatus, having a body, a fuser to fix an image on a recording medium by heat, an interface to accept a value for a first time, which is between an end of fixing by the fuser until entry into a low power-consuming condition for the heater, a fan, and a controller, is provided. The controller sets a second time being a predetermined length and subtract the second time from the first time to obtain a third time. If the third time is given a positive value, the controller continues driving the fan after the end of the fixing and throughout the third time, and inactivates the fan after the third time. If the third time is given a value smaller than or equal to zero, the controller inactivates the fan during the first time before the entry into the low power-consuming condition.

  • Publication number: 20190256336
    Abstract: An aseptic filling machine and an aseptic filling method are provided with which a petaloid-shape bottle or an unstable bottle which is filled with sterilized content and sealed with a sterilized cap in an aseptic atmosphere is discharged without a delay from an aseptic zone to a non-aseptic zone. Further, even if a petaloid-shape bottle or an unstable bottle falls over on a discharging conveyor when being discharged from an aseptic zone to a non-aseptic zone, a stopping time of the aseptic filling machine can be shortened. A barrier chamber into which air containing a gas of a sterilizer is supplied is provided downstream of a sealing portion that fills content into the bottle and seals the bottle with a cap. Further, a discharge portion chamber that shields a discharge portions provided downstream of the sealing portion that fills content into the bottle and seals the bottle with a cap.

  • Patent number: 10384240
    Abstract: Hot water or heated steam is fed to a drink supply pipe line for simultaneously supplying drink to a plurality of filling nozzles, while exhausting the hot water or heated steam from all the filling nozzles, F-values are calculated by detecting temperatures at a plurality of predetermined portions of the drink supply pipe line and all the filling nozzles at every predetermined time interval, and a sterilizing process is ended at a time when a minimum F-value reaches an aimed value. According to such method, the sterilization to the drink supply pipe line can be smoothly performed.
