A mobile body positioning station and a mobile body positioning system include a first partition, a second partition disposed along a direction intersecting an extending direction of the first partition, and a guide device as a guide disposed on a movement path of a robot as a mobile body. The guide device is disposed along an oblique direction with respect to the direction perpendicular to the extending direction of the first partition to extend from the first partition toward the second partition side. The guide device is configured to make the robot move in the oblique direction more easily than move in directions other than the oblique direction, and the guide device moves the robot along the first partition toward the second partition.

Mobile body positioning station and mobile body positioning system

An explosion-proof apparatus includes a frame having a hollow shape; a gas supply device configured to maintain inside of the frame at pressure higher than certain pressure by supplying gas to the inside; an electrical component disposed inside the frame; a battery configured to supply power to the electrical component; a protective device configured to stop power supply from the battery to the electrical component; a battery housing enclosure being an increased-safety explosion-proof enclosure configured to house the battery therein; and a protective device housing enclosure being a flameproof explosion-proof enclosure configured to house the protective device. The battery does not include a management device that manages parameters of the battery.

Explosion-proof apparatus

A charging system includes: a movable body including a frame and a battery provided in the frame; and a charging station configured to charge the battery. The movable body includes: a pressure detection unit configured to detect pressure in the frame; and a charging permission signal output unit configured to output a charging permission signal indicating that the pressure in the frame is detected to be equal to or higher than a threshold pressure. The charging station includes: a charging permission signal acquisition unit configured to acquire the charging permission signal from the charging permission signal output unit; and a power transmission unit configured to execute non-contact charging of the battery when the charging permission signal is acquired by the charging permission signal acquisition unit.

Charging system, charging station, movable body, and charging method

An explosion-proof robot is an explosion-proof robot which is capable of self-propulsion on a field and includes: an explosion-proof casing of a hollow shape inside of which at least one electric component is placed; and a cover including a nonmetal material and covering at least part of an outer surface of the explosion-proof casing.

Explosion-proof robot

An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.

Explosion-proof device

The vibration power generator includes: a plurality of permanent magnets () integrated together to have given inter-magnet gaps under a state in which the same poles of the permanent magnets are opposed to each other; and a plurality of coils () arranged on respective outer peripheries of the plurality of permanent magnets so as to have a distance from the plurality of permanent magnets, and is configured to generate an electric power through relative movement of the plurality of permanent magnets and the plurality of coils. A relationship between a length of the opposed coils and a length of the permanent magnet is set so that the length of the coils is larger than the length of the permanent magnet and equal to or smaller than a sum of the length of the permanent magnet and a length of the inter-magnet gap.

Vibration power generator

An opening and closing device that opens and closes an access port opened from a substantially cylindrical working platform disposed inside a reactor vessel and used to access a nozzle stub of the reactor vessel from the inside of the working platform, the opening and closing device includes: a cover that is slidable along an outer peripheral surface or an inner peripheral surface of the working platform from a closing position where the access port is closed to an opening position where the access port is opened; and moving device for sliding the cover.

Opening and closing device for access port that opens to working platform of reactor vessel

A reactor vessel that performs work inside a nozzle stub of the reactor vessel, including a platform unit that is provided at an upper portion inside the reactor vessel and includes a substantially cylindrical side wall portion and a bottom portion blocking the lower end of the side wall portion; an access window that is provided at the side wall portion of the platform unit an access window moving device that opens and closes the access window; a working device; and a control device that is provided at the outside of the reactor vessel and controls the access window moving device and the working device, wherein the control device drives the access window moving device to open the access window, drives the working device to perform work inside the nozzle stub, and then drives the access window moving device to close the access window after the performance of the work.

Nozzle stub working system for reactor vessel

This repair device includes a casing, a slide shaft slidably arranged with respect to the casing, a turn table rotatably arranged with respect to the slide shaft, and a cutting mechanism installed on the turn table and including cutting tools. The turn table is rotationally displaced while the slide shaft slides in an axial direction, so that the cutting tools helically turn to cut an inner periphery of a nozzle. The cutting mechanism includes a cutting-tool switching unit that switches the cutting tools.

Repair device

This repair device includes a casing, a slide shaft slidably arranged with respect to the casing, a turn table rotatably arranged with respect to the slide shaft, a cutting mechanism installed on the turn table and including a cutting tool, and an advancing and retracting mechanism that displaces a radius of rotation of the cutting mechanism with respect to rotations of the turn table forward and backward. In a state where the casing is centered and positioned with respect to the pipe, the turn table is rotationally displaced while the slide shaft slides in an axial direction, and the advancing and retracting mechanism displaces the cutting mechanism forward and backward. Accordingly, the cutting tool helically turns along an inner peripheral shape of the pipe to cut an inner periphery of the pipe.

Repair device and repair method

In a high-efficiency encoder which performs motion-compensation prediction, an intra-field is set every n fields. The presence of a scene change is detected. When a scene change occurs, a reference picture of motion-compensation prediction is switched, or the field immediately after the scene change is set as an intra-field.

High efficiency encoder and video information recording/reproducing apparatus

Data separating means extracts intra-frame or intra-field encoded blocks from an intra-frame or intra-field encoded, and inter-frame or inter-field encoded digital video signal, and a digital audio signal contained in an input bit stream. Error correction code appending means appends error correction codes to the extracted intra-encoded blocks. Recording means records the data having the error correction code appended, in special replay data recording areas predefined on the magnetic recording tape. During fast replay or slow replay, error correction is achieved even for the replay signal with a low output level and a poor symbol rate.
