摘要： Provided is a technology with which it is possible to minimize generation of excess current from a power source in the case when a scanning unit restarts after having come to a standstill due to reduction in power supply. In the present invention, when a first voltage detection circuit 95 detects, during machining operation using laser beams, that the output voltage from a galvano DC/DC converter 91 has fallen below a first threshold, a controller 6 executes: an action position acquisition process for acquiring a present action position of a galvano scanner 18 on the basis of vector data transmitted to an FPGA 6c from vector data conversion software 6b; a return vector data generation process for, on the basis of the present action position of the galvano scanner 18 thus acquired in the action position acquisition process, calculating return vector data which enables the galvano scanner 18 to return to a reference coordinate value and then causing the vector data conversion software 6b to generate said calculated return vector data; and a return command output process for receiving the return vector data generated from the vector data conversion software 6b in the return vector data generation process and outputting a command for causing the galvano scanner 18 to return to the reference coordinate value on the basis of the received return vector data.

摘要： Provided is a fuel cell unit that can prevent degradation in performance even when the fuel cell is stored for a long time. In the fuel cell unit, in a state where a stack is not supplying electric power to an external load, an air supply channel is closed by an air supply valve (S17) and an air discharge channel is closed by an air discharge valve (S 19) to interrupt supply of the air to a cathode electrode. In the fuel cell unit, a hydrogen discharge channel is closed by a hydrogen discharge valve (S21) and a hydrogen supply channel is opened by a hydrogen supply valve (S23) to supply hydrogen to an anode electrode. In the fuel cell unit, the hydrogen supply channel is closed by the hydrogen supply valve (S25) to interrupt the supply of the hydrogen to the anode electrode. Subsequent to the interruption of the supply of the hydrogen, the fuel cell unit waits until a stack voltage reaches a level lower than a certain voltage threshold. The stack voltage is measured by a voltage measuring unit.

摘要： There is provided a technique installing a memory on a developing cartridge and a drum cartridge, and capable of reducing the number of components in the developing cartridge. A drum cartridge 2 includes a first memory 71 having a first electrical contact surface, and an elastic member 300 that can expand and contract in a second direction. A developing cartridge 1 includes a second memory 81 having a second electrical contact surface, and a developing holder 82 holding the second electrical contact surface such that the second electrical contact surface is movable relative to a casing 10. The developing holder 82 is connected to the elastic member 300 and is movable in the second direction in a state where the developing cartridge 1 is attached to a drum frame 40. Accordingly, wear of the second electrical contact surface is restrained. Also, since an elastic member need not be provided in the developing holder 82, the number of components in the developing cartridge 1 can be reduced.

摘要： Provided are an editing system, a terminal, and an editing program capable of accepting an input operation and executing processing even while loading (uploading or downloading) of data is in progress. A terminal 3A transmits, to a terminal 3B, associated information indicating a position where a first content 4 is to be displayed and a size of the first content 4 to be displayed (S113a). The terminal 3B receives the associated information transmitted by the terminal 3A (S117b). The terminal 3B displays, based on the received associated information, associated images 41A, 42Abased on which the position and the size are identifiable (S119). The terminal 3B accepts an editing operation including at least one of a change operation or an input operation (S301). The change operation is of changing at least one of a position or a size of the associated images 41A, 42A. The input operation is of inputting a second content being different from the first content.
