摘要： In an instant, self-developing, and folding camera, a built-in flash unit is disabled as long as the camera is folded. According to another aspect, the flash is disabled after each photograph until the feed motor that drives the film during development has completed its operation. A collapsible bellows forms a dark space between first and second housing sections. When the bellows are folded the flash is drawn to the first section by coupling means. When the bellows are extended the coupling means draws the flash into an operative position.

摘要： A packet communication system etc., is proposed, which can automatically adjusting the antenna directionality without modifying a wireless interface of a wireless packet forwarding device even if it involves fluctuation in the packet transmission timing due to CSMA/CA etc. An interference evasion unit involves fluctuation in packet transmission timing due to CSMA/CA. A radio emission device can control the emissive direction and/or emission intensity. A packet generation unit adjusts packet features other than its contents (e.g., packet length, transmission intensity) based on a switching sequence for specifying the emissive direction and/or emissive intensity, and generate a switching control packet. An emission control unit measures the switching control packet feature other than its contents, and identifies at least one bit as antenna control information. The emission control unit controls the overall directionality of a directional antenna unit based on a bit sequence including at least one bit thus identified.

摘要： A control packet is broadcast over a route, containing first and second metric values of different transmission characteristics of the route. At a local node, control packets from multiple nodes are received and examined for their source. If the packets are received from upstream nodes, the metrics of the received packets are updated, the second metric is weighted and summed with the first metric to produce a number of combined metrics and a minimum value of the combined metrics is detected. One of the routes having the detected value is selected as a route to an upstream node. If the control packets are received from downstream nodes, the second metric is weighted and summed with the first metric to produce a number of combined metrics and a smaller values of combined metrics are detected corresponding in number to usable antennas and routes of the detected values are selected.

摘要： A transmission power control technique allowing stable and reliable signal transmission in soft handover is disclosed. Each of the base stations involved in soft handover measures an amount of loss of the base station selection signal. When the amount of loss of the base station selection signal exceeds a threshold, the transmission power of the downlink signal is not set to the minimum level but to the normally controlled level. Further, a transmission power update timing of each base station is determined so that the downlink signal received at the mobile station changes in transmission power at a predetermined timing synchronized with that of other base stations.

摘要： An object of the invention is to obtain a high-speed and high-accuracy radio-wave propagation characteristic forecasting system in combination with the launching method by correctly estimating a diffraction phenomenon when a ray passes the vicinity of an edge of a structure. To estimate a radio-wave propagation characteristic in accordance with the ray launching method, when a ray passes the vicinity of an edge of a structure, a diffracted wave is generated at the edge if the distance between the edge and the ray is smaller than the radius of a ray spread. Thereby, it is easy to combine the ray launching method with the conventional ray launching method and it is possible to estimate a high-speed high-accuracy radio-wave propagation characteristic also considering a ray diffracted wave.

The management program executes a procedure for receiving a notice of fault in the volume from the storage devices, a procedure for receiving volume access control information from a plurality of storage devices for specifying the computers that can access the volumes, and a procedure for notifying the fault in the volume to the computers that are permitted to access the volumes based on the volume access control information.
