Title: Method and device for removing nitrogen in gas essentially composed of methane
Inventor: OKUMURA SHINYA
IPC: C10L3/10
Filed: 2011-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for removing nitrogen in gas essentially composed of methane which removes nitrogen in a gas essentially composed of methane, and achieves the efficiency improvement of reliquefaction.SOLUTION: The method for removing nitrogen from gas essentially composed of methane is achieved by implementing: an adsorption stage of preparing three or more adsorption columns filled with adsorbent adsorbing and separating nitrogen and making the adsorbent adsorb nitrogen in a state where pressurizing is performed to prescribed adsorption pressure; a reproduction stage of desorbing nitrogen from the adsorbent in a state where pressure is more reduced than the above adsorption pressure so as to be reproduced; and a pressure recovery stage of reverting the adsorption column in the pressure-reduced state to the adsorption pressure in parallel by the respective adsorption columns. In the meantime, in the respective adsorption columns, the respective stages are implemented by being changed-over in succession. A recovery operation of introducing the gas discharged from the adsorption column in the pressure reduction step upon transfer from the adsorption stage to the reproduction stage, into the adsorption column in the pressure reverting stage, is implemented. In the recovery operation, a first step of recovering the gas of relatively high pressure after the adsorption and a second step of recovering the subsequent relatively low pressure gas thereafter are implemented.

IPC: H02P6/06
Filed: 2011-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a driving device capable of reducing a loss in an inverter which drives an electric motor.SOLUTION: The driving device using an inverter 24 having diodes D1-D6 with smaller conduction resistance than that of transistors Tr1-Tr6 comprises a power factor adjustment circuit 28 which has an electrostatic capacitance variable circuits 28a-28c, where an electrostatic capacitance is variable, and can adjust a motor electric power factor PF which is a power factor of the electric power exchanged between a motor 22 and the inverter 24. Moreover, the motor electric power factor PF is deteriorated by adjusting the electrostatic capacitance of the electrostatic capacitance variable circuits 28a-28c. This allows time during which current flows through a transistor to be shorter in one cycle of the current flowing between the inverter 24 and the motor 22, and time during which current flows through the diode to be longer, thereby reducing a loss in the inverter 24.

Title: Fuel injection device
Inventor: SUGIYAMA KOICHI
IPC: F02M59/36
Filed: 2011-02-18
Abstract: PROBLEM TO BE SOLVED: To follow the actual pressure variation with high accuracy to control a high-pressure pump.SOLUTION: A required fuel flow rate for setting pressure in a common rail to a target pressure is determined, and the operation of the high-pressure pump is controlled based on the determined required fuel flow rate. Even if a pressure variation does not actually occur, the operation of the high-pressure pump is controlled based on the required fuel flow rate. For this reason, since an F/B flow rate is determined based on a difference between the required fuel flow rate and the actual flow rate, the operation of the high-pressure pump is controlled after the required fuel flow rate is substantially learned and corrected so that the pressure in the common rail 4 is set to the target pressure Tp. The high-pressure pump is controlled by following the actual pressure variation with high accuracy.
