摘要： An optical element has three operation modes of light oscillation, light amplification, and light attenuation, which are switched in accordance with the intensity of an excitation component. The optical element having a first light terminal from which a light pulse is output to an optical fiber to be tested, and a second light terminal through which reflected light from the optical fiber is passed in the amplification mode or in the attenuation mode. Light-receiving section receives the reflected light output from the second light terminal of the optical element, and converts the reflected light into an electric signal. Signal processing section subjects the electric signal output from the light-receiving section to a predetermined signal processing step for testing the optical fiber. Excitation component control section outputs to the optical element a first excitation component for enabling the optical element to operate in the oscillation mode at a first timing, a second excitation component for enabling the optical element to operate in the attenuation mode at a second timing subsequent to the first timing, and a third excitation component for enabling the optical element to operate in the amplification mode at a third timing subsequent to the second timing.

摘要： In a magnetic resonance imaging apparatus having a superconducting magnet to form a static magnetic field and capable of producing a magnetic resonance image of a test piece placed in the static magnetic field, a static magnetic field correcting coil corrects the intensity of the static magnetic field, and a power source supplies to the coil a current to form a magnetic field having inverse characteristics with respect to the attenuation pattern of the static magnetic field intensity in the superconducting magnet. Since the static magnetic field correcting coil is supplied with such a current, enhances the stability of the static magnetic field at the time of raising such a magnetic field or immediately after changing the intensity thereof.

摘要： Tertiary alcohols are produced by the hydration of an isoolefin in the presence as catalyst of an acidic cation exchange resin such as a sulfonated styrene-divinylbenzene copolymer, and a polyhydric neo-type alcohol such as neopentyl glycol. The process is useful for separating isobutylene from a hydrocarbon mixture containing its isomers via preparation of the alcohol, separation from the unreacted hydrocarbons and dehydration of the tertiary butyl alcohol to isobutylene.

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.
