Abstract: A high pressure homogenizer segmentalizes material made of minute solid or the like by passing suspension liquid including the material to a small diameter orifice at high speed under high pressure. An injection valve of the high pressure homogenizer includes: a fixed member having a material introducing passage therein; and a movable member disposed rotatably, swingably, or pulsatingly opposite to the fixed member in an axial direction of the fixed member. The orifice of the injection valve is made of a fine gap in a radial direction disposed between an end face of the fixed member facing an end of the material introducing passage and an end face of the movable member disposed at an end of the movable member opposed to the fixed member. The orifice communicates with a material processing passage via a ring-shaped collision wall.

The gateway device interconnects a network, to which an AV/C installed IEEE1394 device is connected, and a network, to which a player device compliant with a UPnP is connected, and includes: a conversion unit for converting Plug-and-Play processing of the IEEE1394 device to each step of Plug-and-Play of the UPnP; a conversion unit for converting an action of a UPnP AV to an AV/C command of the IEEE1394 device; and a stream transfer unit for transferring stream data transmitted from the IEEE1394 device to the IP network.

Abstract: A suspension contains a base material including a fine solid matter. The base material may be in the form of a semifluid matter. The base material is compressed with a high pressure. The compressed base material is passed through an orifice at a high speed. The orifice includes a small clearance defined between (a) the end of the movable valve provided slidably and rotatably in the length direction inside of the cylinder case and (b) the opposing wall surface of the cylinder case. For dispersion, to emulsification, crushing, and subdivision of the base material, there is provided a heat exchange unit including continuous conduits through which a cooling medium can flow, the conduits extending over a desired length in the length direction about the orifice as a source of heat.

Abstract: A high-pressure homogenizing apparatus, in which a material receiving recess can be easily cleaned without disassembling/assembling a pressurizing mechanism, is provided. The apparatus includes a high-pressure homogenizing mechanism (1) in which a suspension (2) or semisolid (2?) containing a raw material (G) is passed through the orifice (3) to be subdivided; and a material receiving passage (8) communicated with the high-pressure homogenizing mechanism (1). One of the inserting member (5) and the material processing piston (4) is moved relatively to each, thereby the suspension or semisolid including the raw material is transferred into the material receiving passage (8) so as to be subdivided and processed. When the material processing piston is moved back over open end (6a) of the material processing recess, the cleaning liquid (W) is introduced through the material receiving passage into the material processing recess and the inside of the material processing recess is cleaned.

Abstract: Image feature values Va and Vb are derived from image data, coefficients C and D are determined based on the image feature values Va and Vb, and an approximate expression expressed with the file size Sfj of the JPEG compression file and the quantization data coefficient value Aqt is derived. Next, by designating the file size of a desired predetermined JPEG compression file based on the approximate expression, the quantization data coefficient value Aqt is derived, and a first quantization table as a reference is multiplied by the quantization data coefficient value Aqt, whereby a second quantization table is obtained. Then, using the second quantization table, the image data is actually JPEG-compressed.

Abstract: The present invention is a high pressure homogenizing apparatus and a method for dividing a fine solid material or fibrous cellulose of chemical, medical, and resin products in suspension as a dispersion or emulsification, or dividing by crushing cell membranes of fungi with high efficiency. The apparatus is free from valve damages to simplify maintenance and control. The high pressure homogenizing apparatus to finely divide a raw material in suspension includes a high pressure homogenizing device having an orifice, a raw material receiving passage connected to the high pressure homogenizing device, a processing piston, and a processing recess disposed in a receiver. A front end of the processing piston is inserted into the processing recess with a pressure intensifier and a volume compression inside the processing recess pressurizes the suspension in the processing recess to lead the suspension into the raw material receiving passage for dividing the raw material.

Abstract: A three-dimensional sound reproducing apparatus is configured by cascading a sound field effect adding unit and a crosstalk canceling unit. The sound field effect adding unit adds a predetermined three-dimensional sound field effect to an input audio signal, thereby generating audio signals respectively corresponding to left and right channels. The crosstalk canceling unit performs a calculation process on the audio signals of the two channels so that, when the audio signals are respectively generated by two loudspeakers positioned in front of a listener, the audio signals reach the left and right ears of the listener without producing crosstalk. The resulting audio signals are supplied to the loudspeakers, respectively.
