20090120445 | INDICATOR FOR CUFFED MEDICAL DEVICE - An indicator for a cuffed medical device, attached to a cuffed medical device to indicate internal pressure in a cuff of the medical device. The indicator includes: an indicator main body which includes a check valve adapted to be connected to an injection means for injecting a fluid into the cuff, a connecting section formed integrally with the indicator main body for connecting to the cuffed medical device, the connecting section communicating with the inside of the cuff, and a communication path for making the check valve and the connecting section communicate with each other; and a balloon provided in the indicator main body. The inside of the balloon is made to communicate with the communication path and is inflatable and deflatable in accordance with the internal pressure in the cuff. The balloon includes an index body which is moved forward and backward in accordance with the degree of inflation and deflation of the balloon in order to make the degree of inflation and deflation of the balloon visually recognizable. With the indicator for a cuffed medical device, a reduction in internal pressure can be readily and precisely determined. | 05-14-2009 |
20090139810 | ROTARY DAMPER - A rotary damper is provided and includes: a housing; an annular ring member that is provided in the housing, and is made of elastomer or flexible rubber; a shaft body that is accommodated in a rotatable manner in the housing; and a sliding portion that is provided in the housing and makes contact with the ring member so as to freely slide with respect to the ring member along the circumferential direction thereof, in which: the ring member has an abutting portion that abuts the sliding portion, and a hollow portion provided inside the ring member; the hollow portion has an opening portion on the side opposite to the abutting portion; in the state of having enclosed gas in the hollow portion, the opening portion is hermetically joined to the inner surface of the housing; a projected portion that engages with the opening portion of the hollow portion is provided on the inner surface of the housing; and a pressing member that presses the ring member toward the inner surface of the housing is provided on the inner side and/or outer side of the ring member in the radial direction. | 06-04-2009 |

20120061966 | WIND POWER GENERATION CONTROL DEVICE AND WIND POWER GENERATION CONTROL METHOD - A wind power generation control device which controls a wind power generator using a wind turbine blade having a fixed pitch angle is provided. The wind power generation control device which controls the wind power generator in which an output current value outputted by the wind power generator is detected, an output voltage value outputted by the wind power generator is detected, a rotational speed of the wind turbine blade is detected, and on the basis of the detected output current value at the current time, the detected output voltage value at the current time, and the detected rotational speed at the current time, output power at the rotational speed at the current time is calculated, and on the basis of the calculated output power and blade aerodynamic properties, which are properties inherent to the wind turbine blade, the wind power generator is controlled so that an optimal amount of power corresponding to the wind speed can be efficiently obtained in a relatively low wind speed region and a wind power generation control method for controlling the wind power generator are provided. | 03-15-2012 |
20130009397 | WIND POWER GENERATION DEVICE - Provided is a wind power generation apparatus to which general purpose inverters are applicable. An inverter in a constant-voltage mode is used. While a wind power generator is generating electricity, switching circuits are turned on and off at a controlled duty cycles to intermittently short-circuit an armature winding, boosting the voltage and controlling the rotational speed of a windmill rotating blade, with the result that the voltage applied to the inverter is made constant. At the activation, in order to prevent an excessive voltage from being generated while an inverter is changing from the stand-by state to the activated state, ON/OFF control of a switching circuit is performed to switch between the output voltage of a rectifier and the voltage generated at a resistor, with the result that the voltage is controlled and maintained at an appropriate value. | 01-10-2013 |
