20120057986 | PRODUCTION METHOD OF IMPELLER APPLIED TO SUPERCHARGER - An impeller comprising a wheel portion extending in an axial direction and a plurality of blades arranged around the wheel portion is produced by assembling a mold divisible into a plurality of parts having a cavity adapted for forming an outer profile of the impeller, injecting a kneaded matter including powder of a metal or a ceramic and binder to mold a green body, degreasing and sintering the green body to obtain a sintered body, embedding the sintered body into a die having a cavity adapted for modifying the outer profile of the impeller, and pressurizing the die to modify the outer profile of the impeller. | 03-08-2012 |
20120133316 | MOTOR CONTROL CIRCUIT - A motor control circuit for a motor is provided. The motor control circuit drives the motor based on torque command data. The torque command data is output by adding speed error data output from a speed error detecting section based on a first reference clock and a speed pulse and phase error data output from a phase error detecting section based on a second reference clock and the speed pulse. Each of the speed error data and the phase error data is output within a detection range set by a setting section provided for each of the speed error detecting section and the phase error detecting section. | 05-31-2012 |
20120299523 | MOTOR DRIVING DEVICE, INTEGRATED CIRCUIT DEVICE, MOTOR APPARATUS AND MOTOR DRIVING SYSTEM - A motor driving device includes a communication path selection unit, to which operation command information for controlling driving of a motor is input in a serial data format or a parallel data format via a common input path, a communication unit which includes a serial interface unit for the serial data format and a parallel interface unit for the parallel data format, and outputs a control signal based on the operation command information input via the communication path selection unit, and a driving control unit which controls driving of the motor based on the control signal. The communication path selection unit selects between outputs path to the serial interface unit and the parallel interface unit, which corresponds to the data format of the input operation command information, and outputs the input operation command information to the serial interface unit or the parallel interface unit through the selected output path. | 11-29-2012 |
20130149129 | VARIABLE GEOMETRY TURBOCHARGER - An exhaust nozzle | 06-13-2013 |
20140043413 | Ink Jet Recording Device - An ink that is unused for printing when a supply ink from an ink container is ejected from a nozzle, and printing is conducted on an object to be printed is sucked by a gutter together with an air, and the ink and air are recovered into the ink container. In this situation, the air mixed with an ink solvent and recovered is discharged as an exhaust gas from the ink container by an exhaust path, and at this time, the ink mist is removed from the exhaust gas in which a liquefaction ink solvent liquefied within the exhaust path and the ink mist are mixed together by an ink mist mixture unit. Thereafter, the liquid is held by the aid of a capillary action, and separated from the gas in a gas-liquid separator to recover the separated liquefaction ink solvent. | 02-13-2014 |
20140043414 | GAS-LIQUID SEPARATOR AND INKJET RECORDING APPARATUS USING THE SAME - A gas-liquid separator includes a casing with a cylindrical chamber inside, a gas-liquid 2-phase inlet pipe which is attached to a wall of the casing and connected to the chamber, a gas outlet pipe for discharging the gas of a gas-liquid mixture flowing into the chamber, and the gas-liquid 2-phase outlet pipe for discharging the liquid as a most part of the gas-liquid mixture flowing into the chamber. A gap is formed around the gas-liquid outlet pipe in the chamber for separating the mixture into liquid and gas using the surface tension and suction force. The gas-liquid separator is installed in the inkjet recording apparatus, especially in the print head. The print head is filled with the solvent gas so as to be suctioned from the gutter to reduce the solvent consumption. | 02-13-2014 |
