  • Patent number: 10351447
    Abstract: Provided is a water treatment system that prevents overlook and misdetection of abnormal flocculation. The water treatment system includes a mix tank, a flocculation tank, a plurality of floc-particle-diameter measurement devices, a fault detection device that detects abnormal flocculation, and a notification device that notifies occurrence of the abnormal flocculation. The fault detection device includes: a calculator that calculates at least one of a difference and a ratio between particle diameters of floc; a storage that stores therein a tolerable range of at least one of the difference and the ratio between the particle diameters of floc; a determiner that, when the calculated value is within the tolerable range, determines that it is normal, and when the calculated value is outside the tolerable range, determines that it is abnormal; and an outputter that transmits an abnormal flocculation detection signal to the notification device.

  • Patent number: 8944900
    Abstract: A game providing system according to an embodiment of the present invention includes one or more processors capable of executing a game program. In one embodiment, the game program includes a conversion rate presentation module configured to present a conversion rate between a first basic point and a first varying point to a player. When a first basic object associated with the first basic point is selected, an acquired point of the player is determined on the basis of the first basic point. When a first varying object associated with the first varying point is selected, the acquired point is determined on the basis of the first varying point.

  • Patent number: 6385421
    Abstract: An image forming apparatus includes a latent image forming mechanism for forming an electrostatic latent image on a photosensitive member, and a developing device for supplying a developing liquid containing at least toner and a carrier liquid, to the photosensitive member on which the latent image is formed, thereby to develop the latent image. The image forming apparatus also includes a removing device for removing an excessive portion of the developing liquid supplied by the developing device, whereby the excessive portion of the developing liquid remains on the photosensitive member after development. The image forming apparatus further includes a returning mechanism for returning the excessive portion of the developing liquid, which is removed by the removing device, into a casing of a developing liquid supply unit for supplying the developing liquid to the developing device, and a reserve flow-in section.
