20090053079 | LIQUID DISCHARGING DEVICE - The liquid discharging device includes a driving mechanism that drives a needle, a measurement plunger member and an inlet valve members that are concentrically-arranged inside a container. The driving mechanism includes: a piezoelectric-element support plate to which piezoelectric elements are attached; a spring for biasing the piezoelectric-element support plate toward a discharge outlet; and a control device adapted to control the piezoelectric elements separately. The piezoelectric-element support plate includes: a base end to which first end sides of the piezoelectric elements are fixed; a drive unit to which second end sides of the piezoelectric elements are fixed; and a displacement expanding portion expanding and outputting a displacement of the drive unit, the drive unit being displaced in conjunction with a expansion and contraction driving of the piezoelectric elements. Since the three members can be driven by the two piezoelectric elements, a driving at high speed can be realized and the liquid discharging device can be easily downsized. | 02-26-2009 |
20100062094 | GAS HYDRATE COMPRESSION MOLDING MACHINE - A molding machine for production of gas hydrate pellets under a high pressure in gas hydrate forming conditions, which is inexpensive through minimizing of the use of expensive mechanical seal. The molding machine comprises two forming rolls each fitted to a rotary shaft whose both ends are supported by bearings; a drive unit for rotating the forming rolls; a screw transfer unit for supplying powder to the forming rolls; and a high-pressure vessel, wherein the bearings, the rotary shaft and the forming rolls are all disposed in the high-pressure vessel. | 03-11-2010 |
20100205859 | APPARATUS FOR PRODUCING GAS HYDRATE PELLET AND PROCESS FOR PRODUCING GAS HYDRATE PELLET WITH THE SAME - In producing gas hydrate pellets by compression-molding a gas hydrate powder, heat generated in a compressing part is removed with a simple method so as to reduce the degree of gas hydrate decomposition, and a gas hydrate aggregate blocking the compressing part is promptly and easily removed. A gas-hydrate-pellet production apparatus A is characterized by including: a roll-cooling mechanism which causes cooling water to flow through outer peripheral portions and/or insides of rolls | 08-19-2010 |
20100244292 | PROCESS AND APPARATUS FOR PRODUCING GAS HYDRATE PELLET - Provided is a process and an apparatus for producing at low cost gas hydrate pellets having an excellent storability. A gas hydrate generated from a raw-material gas and raw-material water is dewatered and simultaneously molded into pellets with compression-molding means under conditions suitable for generating the gas hydrate while the gas hydrate is generated from the raw-material gas and the raw-material water that exist among particles of the gas hydrate. | 09-30-2010 |
20100260633 | TUBE PUMP AND TUBE FOR TUBE PUMP - A tube pump includes tubes, hooks, tube receivers, three or more fingers, and a drive mechanism. The tubes each include intermediate tubes, connectors, and end tubes. The tubes are attached by engaging the connectors with the hooks provided on upper and lower sides. The intermediate tubes are provided along the tube receivers. Tube press portions of the fingers are provided between the intermediate tubes. The fingers are driven by the drive mechanism so that the tube press portions are reciprocated between a position where one of the intermediate tubes is squeezed and a position where the other of the intermediate tubes is squeezed. | 10-14-2010 |
20120285083 | PROCESS AND APPARATUS FOR PRODUCING GAS HYDRATE PELLET - Provided is a process and an apparatus for producing at low cost gas hydrate pellets having an excellent storability. A gas hydrate generated from a raw-material gas and raw-material water is dewatered and simultaneously molded into pellets with compression-molding means under conditions suitable for generating the gas hydrate while the gas hydrate is generated from the raw-material gas and the raw-material water that exist among particles of the gas hydrate. | 11-15-2012 |
20130041557 | AUTOMATIC STEERING APPARATUS - An automatic steering apparatus that can suppress steering wheel vibration and that can also smooth angular control. In the automatic steering apparatus, a motor that steers steered wheels is controlled by a control unit. Information from an angle sensor that generates a signal that corresponds to a steering angle of the steered wheels is sent to the control unit. The control unit corrects a target steering angle of the steered wheels such that angular acceleration of the target steering angle is less than or equal to a limiting value. The control unit controls the motor such that the steering angle of the steered wheels tracks the corrected target steering angle based on the information from the angle sensor. | 02-14-2013 |
20130154538 | MOTOR CONTROL SYSTEM AND SAFETY MONITORING SYSTEM THEREFOR - Each of a host controller and a motor control apparatus included in a motor control system that drives a motor includes a step of determining, with respect to motor rotation state estimation information estimated based on an electric current and a voltage to the motor, whether an operation state of the motor is normal according to what kind of a relation an operation command output by the host controller and a detected motor position or motor speed have. | 06-20-2013 |
