  • Patent number: 11542157
    Abstract: Provided is a microchip that can achieve a favorable bonding state in the bonding portion between first and second substrates even if the microchip is large in size. A microchip includes a first substrate made of a resin and a second substrate made of a resin, the first substrate and the second substrates being bonded to each other, and a channel surrounded by a bonding portion between the first substrate and the second substrate is formed by a channel forming step formed at least in the first substrate. Further, a noncontact portion is formed to surround the bonding portion, and an angle ?1 formed between a side wall surface of the channel forming step and a bonding surface continuous therewith satisfies ?1>90°.

  • Publication number: 20220175986
    Abstract: Disclosed herein is a method for decontaminating an object to be treated by reducing the activity of endotoxin in a simple manner. The decontamination method includes a step (a) of irradiating an object to be treated with ultraviolet light of a wavelength of less than 200 nm to reduce activity of endotoxin attached to the object to be treated.

  • Patent number: 8472064
    Abstract: The present invention provides a print module, an information processing device, a print system, a print unit, an ink supply unit, a print method and program, all capable of quickly and easily meeting demands for a print medium size change, particularly to increased sizes, while at the same time coping with demands for faster printing speed. To this end, this invention constructs the print heads (811) in the form of print modules (M) so that their ink systems and signal systems are independent among the print modules. Each print module is set with identity information for its identification.

  • Publication number: 20110157614
    Abstract: This invention provides an image processing method and image processing apparatus, which allow the user to select an image for which an amount of printing material applied to a printing medium is to be reduced. To an object selected on a selection window, a CPU applies image processing for reducing a printing material to data of an internal part of the selected object except for its contour using a program of a printer driver. Then, this invention can provide an image processing method and image processing apparatus, which are convenient for the user.

  • Publication number: 20070263244
    Abstract: To meet a demand for changing a print medium size, particularly for increasing the size of print medium while at the same time satisfying the demand for higher printing speed. To that end, a plurality of printer units (116), which are spatially independent of each other (separate from each other) and also independent in the signal system and the ink system, are arranged in an appropriate layout to allow for a line-sequential printing. An information processing device (100) divides a generated image into a plurality of pieces of print data and transfers them to the plurality of printer units. A transport device (117) is installed to feed a large-sized print medium to an area where the plurality of printer units are arranged. The transport device transfers to each of the plurality of printer units a print timing signal corresponding to the position of each printer unit.

  • Patent number: 4548537
    Abstract: An apparatus for taking up a plurality of rod type materials one by one from a pile of such materials is disclosed in which a plurality of rod type materials are stored temporarily in a rack. A part of a rod type material is separated from the plural rod type materials by a take-up element provided on the rack, and the separated rod material is gripped by a clamp provided in opposition to the take-up element. The rod type material fixed in the clamp is then drawn through a drawing element to be completely separated from the remaining rod type materials in the rack.
