20120238675 | METHOD OF PRODUCING AN INK COMPOSITION FOR OFFSET PRINTING - The present invention provides a method of producing an ink composition for offset printing with use of a crude copper phthalocyanine pigment and/or an active crude copper phthalocyanine pigment and without use of a pigment dispersion resin that requires additional cost, to produce an ink composition which provides a highly tinted and bright image. The method includes the steps of: premixing a premix component through stirring so as to obtain a pigment mixture, the premix component containing a crude copper phthalocyanine pigment and/or an active crude copper phthalocyanine pigment, at least one binder resin selected from the group consisting of a rosin-modified phenolic resin, a rosin-modified maleic acid resin, a petroleum resin, and an alkyd resin, and an oil component; grinding and milling the pigment mixture obtained by the premixing, using a bead mill with grinding media of beads each having a size of 0.1 mm or larger and smaller than 1.5 mm, at a temperature within the range of 0° to 180° C., thereby obtaining a pigment dispersion; and further adding the binder resin and/or the oil component to the pigment dispersion and stirring the resulting dispersion, wherein the method satisfies the conditions that (1) the pigment mixture contains 5 to 40% by mass of the crude copper phthalocyanine pigment and/or the active crude copper phthalocyanine pigment, (2) the pigment mixture contains 5 to 500 parts by mass of the binder resin, for each 100 parts by mass of the crude copper phthalocyanine pigment and/or the active crude copper phthalocyanine pigment, and (3) the pigment mixture has a viscosity of 0.001 to 20 Pa·s at the temperature of the grinding and milling. | 09-20-2012 |

20140119274 | RELAYING DEVICE AND COMMUNICATION SYSTEM - A relaying device includes a wireless apparatus interface, a signal processing unit connected to the wireless apparatus interface, a network interface, and a packet processing unit connected to the network interface. The relaying device is provided with multiple communication paths including the wireless apparatus interface, the signal processing unit, and the packet processing unit, and each communication path has a mixing unit configured to additively synthesize an uplink audio signal and a downlink audio signal of other communication path to the uplink audio signal and input the synthesized signal to the packet processing unit, and configured to additively synthesize an uplink audio signal and a downlink audio signal of other communication path to the downlink audio signal and input the synthesized signal to the signal processing unit. | 05-01-2014 |
20140179327 | RELAYING DEVICE - A relaying device includes an uplink interface that continuously receives an audio signal in communication, a wireless apparatus interface to which a repeater acting as a wireless relaying apparatus is connected, a voice buffer that buffers the audio signal, and a control unit. The control unit performs a VOX processing of detecting whether or not a level of the audio signal is equal to or higher than a preset threshold. When the level of the audio signal is equal to or higher than the threshold, the control unit starts buffering the audio signal in the voice buffer, and requests the repeater to reserve a channel. After receiving, from the repeater, a reply indicating that a channel has been reserved, the control unit reads the buffered audio signal from the voice buffer, and transfers this audio signal to the repeater. | 06-26-2014 |
