  • Patent number: 8090305
    Abstract: Disclosed is a fixing device including a liquid supply unit that supplies a liquid fixer containing a softening agent that dissolves or swells at least part of resin to soften the resin; an air supply unit that supplies air for foaming the liquid fixer; and a foam generation unit that mixes the liquid fixer from the liquid supply unit with the air from the air supply unit to generate foams. The foam generation unit has an air channel where the air from the air supply unit flows, a liquid-fixer channel provided such that the liquid fixer from the liquid supply unit flows from a direction opposite to a flowing direction of the air channel, and an air-and-liquid mixing part that mixes the air from the air channel with the liquid fixer from the liquid fixer channel so as to be opposite to each other, thereby generating a foam-like fixer.

  • Patent number: 8085312
    Abstract: An image input apparatus that inputs an image of an object residing within a living body is disclosed. The image input apparatus includes a light source that irradiates near infrared light on the living body, a lens array arranged at a position facing the living body and including plural lenses each having a face with zero or negative power arranged at a side facing the living body and a face with positive power arranged at a side facing an image surface, an imaging unit arranged at the image surface side of the lens array that forms a compound-eye image corresponding to a collection of ommatidium images formed by the lenses of the lens array, and a reconstruction unit that reconstructs a single image from the compound-eye image using a parallax between the ommatidium images. The reconstructed single image is input as the image of the object.

  • Patent number: 5559645
    Abstract: In a signal processing unit for writing/reading data on/from a disk-shaped recording medium of a disk apparatus, all of a data separator, a code decoder circuit, a code encoder and a write compensation circuit are constructed on a one-chip integrated circuit. The data separator separates a synchronization clock from a code data reproduced from the disk. The code decoder circuit produces decoded data from the synchronization clock as the output from the data separator, and synchronized code data. The code encoder encodes data supplied from a host computer or a disk controller into code data. The write compensation circuit compensates for a peak shift with respect to write code data. This integrated circuit is fabricated by a Bipolar-CMOS process by which a bipolar transistor and a CMOS transistor are mixed with each other thereon.

  • Patent number: 5109500
    Abstract: A disk control unit for writing data on or reading the same from a disk in a disk apparatus in response to an instruction from a host computer. The disk control unit has a plurality of command buffers for storing a group of operation information and operation length information corresponding to individual fields in the disk format of the disk apparatus. Prior to processing the length information is set in a counter and then is counted decrementally with progress of the processing steps, whereby an operation end signal is produced to control an address generator for the command buffers. The disk control unit also has a pointer register for storing a jump point address in response to indication of the operation information and outputting the stored address in response to indication of the other operation information to change the address of the address generator.
