摘要:
An apparatus for removing, by means of a scraper, an electroplating metal deposited onto the surface of a conductor roll for electroplating. The above-mentioned removal is accomplished by pressing the scraper (23) arranged near the conductor roll (5) against the conductor roll (5). The start and the end of the removal can properly be controlled on the basis of a value of potential difference between a reference electrode (21) immersed in the electroplating solution and the conductor roll (5), as measured by means of a potentiometer (25). The scraper (23) return-travels, together with the reference electrode (21), in the axial direction of the conductor roll (5) by the action of a scraper moving mechanism (30).

摘要:
According to one embodiment, a measurement system includes a wireless relay device, a moving-object-mounted terminal and a data processor. The wireless relay device forms a wireless area for performing wireless communication. The moving-object-mounted terminal is mounted to a moving object within the wireless area. The moving-object-mounted terminal includes a Global Positioning System (GPS) unit and a wireless unit. The GPS unit acquires positional data of the moving object and time data indicating the time when the positional data has been acquired by GPS. The wireless unit converts the positional data and the time data into a wireless signal, and transmits the wireless signal to the wireless relay device. The data processor receives the wireless signal from the moving-object-mounted terminal via the wireless relay device, and calculates time required for the moving object to move a predetermined distance within the wireless area based on the positional data and the time data.

An air escape hole 7ffor escaping an air, which is confined in the protection sleeve 87 when the protection sleeve 87 is thermally shrunk and adhered closely to the optical connector ferrule 85, to the outside is formed in the optical connector ferrule 85.
摘要:
An optical connector in which the housing property into a cabinet or the like can be enhanced because of the compactification, and which can solve problems of the increase of the bending loss of an optical fiber, the breakage, and the like is obtained. In an optical connector which houses and holds a fusion spliced portion where a short optical fiber previously fitted to an optical connector ferrule is fusion-spliced with a coated optical fiber, one end of a protection sleeve which armors the fusion spliced portion is coupled to the optical connector ferrule. As a result, the length of the protection sleeve which covers the fusion spliced portion so that the fusion spliced portion is positioned at the middle can be set with reference to an end portion of the optical connector ferrule. Therefore, the protection sleeve can be shortened, and compactification of the optical connector can be realized.
摘要:
A target-pixel-setting section (31) sets a target pixel in a target image to be predicted. A motion-direction-detecting section (32) detects a motion direction corresponding to the target pixel. A pixel-value-extracting section (36) extracts from peripheral images corresponding to the target image, in order to extract a main term that mainly contains component of the target pixel in a moving object that encounters a motion blur in the peripheral images, at least pixel values of pixels in the peripheral images whose space position roughly agree with space position of the target pixel. A processing-coefficient-setting section (37a) sets a specific motion-blur-removing-processing coefficient. A pixel-value-generating section (38a) newly generates pixel values for processing from the pixel values extracted by the pixel-value-extracting section (36) corresponding to the motion direction and generates pixel values corresponding to the target pixel based on the pixel values for processing and the specific motion-blur-removing-processing coefficients. It is possible to perform a robust motion-blur-removing processing on any shifts of motion vector.
