  • Publication number: 20210252473
    Abstract: An active carbon molded body that comprises a plurality of active carbon granules that are foiled from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. A plurality of communicating holes are foamed in the active carbon molded body. A pore size distribution curve obtained for the active carbon molded body by a mercury intrusion has: a first peak that is from first pores that are famed between active carbon particles; and a second peak that is from second pores that are foamed between active carbon particles and is for a smaller pore size than the first peak. The present invention thereby provides an active carbon molded body that has high water purification capacity and has a filtration flow rate that is at least a prescribed value.

  • Publication number: 20210252474
    Abstract: A fibrous granulation binder that is for active carbon granules that are formed from aggregates of active carbon particles and has a D50 particle size, as measured by laser diffraction, of 3.5-86.7 ?m. When a fibrous binder is used to produce active carbon granules, setting an appropriate particle size for the fibrous binder makes it possible to reliably produce high-strength active carbon granules.

  • Publication number: 20210245134
    Abstract: An active carbon molded body that comprises a plurality of active carbon granules that are formed from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. The active carbon molded body is formed as a result of the plurality of active carbon granules being aggregated by means of the fibrous granulation binder in the active carbon granules. The present invention is also an active carbon molded body production method in which active carbon granules that have been formed by aggregating active carbon particles by means of a fibrous binder are molded by simultaneous application of heat and pressure without separate addition of a molding binder. The present invention thereby provides: an active carbon molded body that has high purification capacity and good production efficiency; and a production method for the active carbon molded body.

  • Patent number: 8998371
    Abstract: An image forming apparatus includes an image forming device, a conveyance unit, a correction unit, and an attitude controller. The image forming device forms an image on a printing medium. The conveyance unit is disposed opposing the image forming device to convey the printing medium. The correction unit corrects an attitude of a leading edge of the printing medium sent out from the conveyance unit. The attitude controller controls correction of the attitude of the leading edge of the punting medium performed by the correction unit. The attitude controller determines whether or not the correction of the attitude of the leading edge of the printing medium is to be performed, and causes the correction unit to perform the correction when the attitude controller determines that the correction is to be performed.

  • Patent number: 7131252
    Abstract: An automatic packaging apparatus has an arraying and supplying station, a sorting station and a packaging station. The arraying and supplying station forcibly arrays and supplies encased products to orient their caps in one direction. The sorting station selectively sorts the arrayed encased products to a first feed path for feeding the encased products to package the encased products in a abreast-arrayed attitude and a second feed path for feeding the encased products to package the encased products in a tandem-arrayed attitude. The packaging station automatically packages the encased products by a shrink sheet in the abreast-arrayed attitude or the tandem-arrayed attitude.

  • Patent number: 5200730
    Abstract: A noise suppressor for engagement over a cable, comprises a ferrite core having a core passage extending therethrough from one end to the other. A sleeve of resilient insulating material is cast, injected, dipped or molded over the ferrite core to cover the core. The sleeve includes on opposite sides thereof, a sleeve passage communicating with the core passage. One of the projections may be resilient or may be replaced by a closed end of the sleeve with a slit, for closely engaging a cable to fix the sleeve at a selected location along the cable. A pad may be included in one or both of the sleeves to further hold the sleeves securely on the cable. The sleeve may have a cylindrical or rectangular cross section to accommodate cylindrical or ribbon shaped cables.
