  • Publication number: 20100101897
    Abstract: In an elevator device, movement of a car is braked by a brake device in a state in which driving of a hoist is stopped. While the drive of the hoist is stopped, braking force of the brake device is controlled by a brake control device based on a signal from a movement detector that generates a signal corresponding to movement of the car. The brake control device generates a target pattern for at least one of speed and acceleration of the car and controls braking force of the brake device such that the movement of the car follows the target pattern.

  • Publication number: 20100078267
    Abstract: A car is suspended by suspension means and raised and lowered by means of a hoisting machine. Electric power supplied to a motor of the hoisting machine is controlled by an electric power converter. The electric power converter is controlled by means of a control apparatus. The control apparatus estimates a maximum value of a regenerative voltage at time of a regenerative operation of the hoisting machine when the car is running. When the estimated maximum value of the regenerative voltage reaches a predetermined voltage limit value, the control apparatus controls the electric power converter so as to stop an increase in estimated maximum value of the regenerative voltage.

  • Publication number: 20090167176
    Abstract: A PDP can be driven at low voltage while having a charge retention property in a protection layer, and has favorable image display properties. Additionally, the PDP prevents the occurrence of discharge delay and realizes high-quality image display by performing favorable high-speed driving in a high definition PDP. To achieve this, a surface layer (8) is formed to a film thickness of 1 ?m in an oxygen atmosphere having an oxygen partial pressure of 0.025 Pa or more, the surface layer (8) is provided on a face of a dielectric layer (7) on a discharge space side. Furthermore, MgO particles (16) are dispersed on a surface of the surface layer (8). The surface layer (8) has the effects of protecting the dielectric layer (7) from ion bombardment during discharge, reducing the firing voltage, and preventing excessive electron loss. Also, the MgO particles (16) have a high initial electron emission property.

  • Publication number: 20090022109
    Abstract: The present invention provides a mobile terminal and a method of executing scanning for radio signals in the case where the mobile terminal is connectable to multiple radio communication systems employing different radio communication schemes. The mobile terminal and the method can scan for radio signals transmitted from a radio base station at an appropriate timing without modifying the existing radio base station or the like. The mobile terminal includes a WLAN controller configured to cause a WLAN communication unit to execute scanning for radio signals transmitted from an access point. Scanning is executed if a scrambling code determining unit determines that a scrambling code contained in notification matches a scrambling code stored in a scrambling code information storage, and if a position determining unit determines that a certain position indicated by position information stored in a GPS position information storage is within a predetermined distance from a current position of the mobile terminal.

  • Patent number: 6268878
    Abstract: A head controller 2 reads out adjustment data from a ROM 3 immediately after a power-on operation. The adjustment data is prepared for adjusting unevenness of light emission from LEDs in a LED head 5. A buffer memory 4 stores the read adjustment data. The head controller 2 reads the adjustment data from the buffer memory 4 with high data transfer rate, and obtains bitmap data from a frame memory or the like (not shown). The head controller 2 sends the read bitmap data and the adjustment data to an anode driver 51. The head controller 2 sends a strobe signal to the anode driver 51 and a cathode driver 53. The anode driver 51 adjusts ampere of supplied currents (i.e. drive signals corresponding to the bitmap data) from the head controller 2, in accordance with the received adjustment data in response to the reception of the strobe signal. The adjusted drive signals are sent to LED array chips 52.
