A wireless communication device that transmits packets, on the basis of a packet transmission scheme for allocating wireless bands with virtual carrier sensing, has: monitoring module for monitoring packets communicated between other wireless communication devices and base stations for a local cell and another cell; determination module for determining whether a possibility exists that a local station receives other-cell interference resulting from communication between the wireless communication device in the other cell and the base station, on the basis of the monitoring result; occupancy period detection module for detecting an occupancy period occupied due to communication between the wireless communication device in the other cell and the base station, on the basis of the monitoring results, when determination is made that receiving the other-cell interference is possible; and timing recognition module for recognizing a timing for avoiding the other-cell interference in a predetermined period on the basis of the occupancy period.

A cooling structure includes a heat dissipation structure having a heat generator and a heatsink that is adhered through an insulating adhesive layer to at least a surface of the heat generator that faces a cooling fluid and made of a metal foil having the flexibility. A fluid flow path is disposed outside of the heat dissipation structure so that the cooling fluid flowing inside thereof and the heatsink may directly come into contact. Further, a fine recess is disposed on a surface of the heatsink that directly comes into contact with the cooling fluid.

A system and method for setting a software option of a numeric control device, by which a user cannot set the options without permission and a cost regarding option configuration may be recovered by a maker. A maker PC generates option setting data for setting bit information to one or zero, based on a name or a number of a software option to be set, in order to make the function of the software option valid or invalid. This data is encoded or encrypted by using a unique identification number of a control device. The control device reads and decodes the encoded software option setting data, in order to set data of the corresponding memory address and bit number in the control device to one or zero. By using the unique identification number of the control device, only the control device, the software option setting data of which is required, can decode the encoded data.
摘要:
A vapor-lift pump heat transport apparatus having a small heat resistance and a large heat transport capacity. A heat exchange circulating solution container has a first space and a second space communicating with the first space through a communication opening and contains a heat exchange circulating solution, and vapor thereof, in each space. A circulating solution transport passage includes a pipe connected to the solution outlet of the container and provided with a sensible heat releasing heat exchanger, a pipe disposed in the container, and a pipe connected to a vapor-liquid two-phase fluid inlet and provided with a heating heat exchanger. A vapor-liquid two-phase fluid flows into only the first space through the vapor-liquid two-phase fluid inlet. When the entrance of the vapor-liquid two-phase fluid has caused a pressure difference between the first and second spaces, a difference occurs between the positions of the vapor-liquid interfaces in the first and second spaces.

The image displaying apparatus of the present invention provides a first display mode in which a first display region for one screen image is formed in a display screen, with the short side direction of the display screen aligned with the vertical direction; and a second display mode in which a first display region and a second display region for two screen images are formed in the display screen, with the long side direction of the display screen aligned with the vertical direction, and the first display region and the second display region formed such that they are arranged up and down. According to this configuration, when images are displayed in a double screen, each image can be displayed as large as possible.

A relay failure detecting device able to detect reliably a fault in a relay circuit that provides alternating current power to a load through a relay that is a double-pole switch. Individual common terminals of first and second relays are connected individually to a pair of outputs terminals of an alternating current power supply, individual normally-open terminals of the first and second relays are connected to a pair of power supply input terminals, and a dummy load that is driven by the alternating current power supply through a diode between the individual normally-closed terminals of the first and second relays is provided. A fault in the first and second relays is evaluated from the state of operation of the dummy load when the first and second relays are not driven.
