A fusion splicing system according to one embodiment includes: first and second electrodes that fusion-splice optical fibers by discharge; a fusion splicing device that has a discharge circuit that outputs a control signal to the first electrode and receives a feedback signal of the control signal from the second electrode; and a deterioration determination unit that determines from a state of the feedback signal whether or not the first electrode and the second electrode are deteriorated.

Fusion splicing system, fusion splicing device, and deterioration determination method

A fusion splicing apparatus includes a fusion splicing unit, a clock unit that outputs a current date and time, and a fusion control unit that controls an operation of the fusion splicing unit and stops the operation of the fusion splicing unit when a remaining period of use known on the basis of the current date and time output from the clock unit and a usable period input from the outside in advance is zero or less. The fusion control unit records information on the number of times of electric discharge per unit period when the clock unit is normal and determines the remaining period of use assuming that the unit period has elapsed when the number of times of electric discharge has reached the number of times of electric discharge per unit period in a case in which an abnormality of the clock unit is detected.

Fusion splicing device

A fusion splicer is disclosed. The fusion splicer includes a fusion splicing unit that fusion splices of optical fibers, a communication unit that communicates through wireless connection with an external terminal, and a setting unit that sets a fusion condition of the fusion splicing unit. The communication unit acquires information related to the fusion condition of the fusion splicing unit from the external terminal. The setting unit sets the fusion condition of the fusion splicing unit based on the acquired information related to the fusion condition. The fusion splicing unit fusion splices in accordance with the fusion condition set by the setting unit.

Fusion connection device, wireless information terminal, fusion connection system, and fusion connection method

A system for releasing locking of a fusion splicer includes a fusion splicer, an information terminal, and a server. The fusion splicer locks a fusion-splicing function in accordance with a predetermined lock condition and releases the locked function in accordance with a release command input. The server includes a storage unit that stores authentication information provided by a user of the fusion splicer, a collation unit that collates authentication information provided from the information terminal with the authentication information stored in the storage unit, and a password issuance unit that issues a one-time password including at least a date in an algorithm when a collation result is favorable. The information terminal authenticates the one-time password in consideration of a day difference or a time difference between the information terminal and the server and applies the release command to the fusion splicer when an authentication result is favorable.

A fusion splicer is capable of sensing whether or not the fusion splicer is in a stolen state in cooperation with a theft sensing device. The fusion splicer includes an authentication processing unit that authenticates the theft sensing device, a storage unit that stores identification information of the theft sensing device subjected to authentication processing, a decision unit that decides whether or not the fusion splicer is in a stolen state based on a communication condition with respect to the theft sensing device, a locking unit that locks at least a part of functions of the fusion splicer when it is decided that the fusion splicer is in a stolen state, a releasing unit that temporarily releases the locked function of the fusion splicer, and an input unit that receives an input of a release ID for releasing the locked state.

An electronic device has an operating panel. A through-hole penetrating the operating panel is provided at a part of the operating panel. A partition board includes a board part and a partition part, and a step is provided between the board part and the partition part. In an area where the through-hole and the board part of the partition board are to be formed, a metal mold can be thickened. In an area where a narrow gap on a surface side of the operating panel is to be formed, the length of the metal mold can be reduced. Therefore, the strength of the metal mold can be maintained. Also, the step of the partition board, which separates the board part and the partition part, prevents visual recognition of the through-hole by a user.

Electronic device

A first substrate is fixed to a case. A heat-generating component is placed so as to be in contact with a radiator. A second substrate is mounted with the heat-generating component, and the second substrate is connected with the first substrate. The second substrate is put between the case and the radiator so as to be interposed and insulate between them. The first substrate and the second substrate comprise an assembly-guiding structure for assembling the second substrate and the first substrate at a certain assembly position. The assembly-guiding structure is composed of the first substrate defining a projection and the second substrate defining an opening. The amount of heat transfer from the radiator to the case is reduced.

The present invention provides an electronic equipment has an operation tool with crashing function. An operation toolis supported on an encoderserving as a support member. In the operation tool, an outer knobserving as an operation portion is to be operated by an operator. A mounting cylindrical portionserving as a mounting portion is formed such that it has a clearance S with respect to the outer knobin the impact acting operation. And, a crashable connecting portionconnects together the operation portion and mounting portion and can be crashed due to an impact given to the operation portion to thereby allow the operation portion to move with respect to the mounting portion. The crashable connecting portionextends radially from the mounting cylindrical portionand is connected to the outer knoband includes plural bridge portions formed radially.

Electronic equipment

A button holding base member includes a button housing portion. A button is so housed in the button housing portion as to move in a button pushing direction. A button holder is assembled from the back side of an operation panel with the button. The button holder and the button interpose the operation panel inbetween thereby to prevent an illuminating light leakage. Moreover, the button holding base member and the button holder include a sliding portion at a position away from the button housing portion. As a result, the sliding structure is arranged independently of the illuminating light leakage preventing structure thereby to elongate the sliding distance. The stability of the button can be improved while retaining the illuminating light leakage preventing function.

A method of manufacturing a positive electrode foil of an aluminum electrolytic capacitor is provided in which anodizing conditions are optimally determined and automatically set to minimize the loss of production and to produce a constant quality of the positive electrode foil. The method comprises an etching process and an anodizing process. An etched foil produced in the etching process is subjected to a constant current inspection, and then, the anodizing conditions are determined from the result of the constant current inspection. The anodizing conditions are transferred to a control panel in the anodizing process where they are automatically registered as its settings. Also, an apparatus for manufacturing the positive electrode foil is provided which has a voltage sensor connected between an output running roller and cathode electrodes in an anodizing tank. A voltage measured by the voltage sensor is fed back to a direct-current source for controlling its output voltage.
