| 20080303464 | Brushless Dc Motor and Electric Apparatus Mounting It - Current control circuit controls an output voltage of DC power supply so as to increase current passing through inverter circuit as the motor increases its the speed. The control offers an RPM—torque characteristic of the motor in which torque increases as the RPM increases. By virtue of the RPM—torque characteristic, a ventilating device employing brushless DC motor exhibits preferable air quantity—static pressure characteristic where less change in air quantity is expected even when a pressure loss-outside wind pressure, duct length or the like—varies. | 12-11-2008 |
| 20090104034 | BLOWER AND ELECTRIC DEVICE WITH SUCH BLOWER MOUNTED THEREON - A supply current control circuit controls the voltage of a low-voltage direct-current power source so that the average current of an inverter circuit detected by a current detecting circuit becomes constant at a specified current value. Accordingly, characteristics that are little in the amount of change of air volume are obtained. | 04-23-2009 |
| 20090108785 | AC-INPUT TYPE BRUSHLESS DC MOTOR AND ELECTRIC APPLIANCE MOUNTING THE SAME - In an AC-input type brushless DC motor, a current control circuit controls an average current of an inverter circuit, a current indication circuit makes addition or subtraction, with respect to a reference current value, to the average current to be supplied to the inverter circuit such that the average current falls into a correlation indicated by a correlation indication circuit. The foregoing structure allows setting speed-torque characteristics of the brushless DC motor such that the torque increases at a higher rpm of the motor. The characteristics are good for driving a fan. | 04-30-2009 |
| 20090129017 | BLOWER AND ELECTRIC DEVICE WITH SUCH BLOWER MOUNTED THEREON - A supply current control circuit controls the voltage of a low-voltage direct-current power source so that the average current of an inverter circuit detected by a current detecting circuit becomes constant at a specified current value. Accordingly, characteristics that are little in the amount of change of air volume are obtained. | 05-21-2009 |
| 20110000652 | VENTILATION DEVICE AND ELECTRICAL EQUIPMENT IN WHICH SAME IS INSTALLED - Having a correlative relation indicator for indicating a correlative relation so that the supply current to be supplied to an inverter circuit may be varied proportionally to the voltage applied to the inverter circuit, a supply current value controller controls the average current to be supplied to the inverter circuit so as to be equal to the value of the supply current indicated by the correlative relation indicator, and therefore if the pressure loss or the static pressure is changed, a wind volume-static pressure of high precision extremely small in the changing amount of wind volume is realized. | 01-06-2011 |
| 20110193430 | MOLDED MOTOR - A molded motor including a stator including a housing formed by integrally molding an armature winding and a printed circuit board with resin containing a fibrous reinforcing material and filler; a magnet rotor rotatably disposed to face the stator; and a plurality of lead wires led out to outside. The printed circuit board is provided with a plurality of lands connecting the lead wires by soldering, and a round hole between the plurality of lands filled with the resin, and the reinforcing material is oriented in a board thickness direction of the printed circuit board. | 08-11-2011 |

| 20080232586 | INFORMATION TERMINAL APPARATUS, INFORMATION PROCESSING APPARATUS AND INFORMATION COMMUNICATION SYSTEM - When transmitting position/time information calculated by means of a GPS function to a server apparatus, authentication is carried out with the server apparatus. The position/time information may be certified as legitimate measured by a portable apparatus with a GPS reception function employed by a user. When transmitting information related to the position and the time acquired from a portable phone terminal having the GPS function and a network function by means of the GPS function to the server apparatus, authentication is carried out between the portable phone terminal and the server apparatus. The position/time information is transmitted to the server apparatus, only if the server apparatus is authenticated as a legitimate counterpart for connection. A secret key holding section is provided for holding different secret keys for different apparatuses. The position/time information measured based on an electromagnetic wave received from a positioning satellite is digitally signed by means of the secret key. The identification information and the position/time information having the digital signature are then transmitted to a counterpart. | 09-25-2008 |
