摘要:
Wireless line termination units 21 and 22 respectively transmit and receive frames via wireless lines 51 and 52. Line termination units 25 and 26 respectively exchange frames with the wireless line termination units 21 and 22. The wireless lines 51 and 52 are treated as one virtual line. A radio monitoring unit 272 monitors the state of the wireless lines 51 and 52, and in accordance with the redundancy mode, instructs the wireless line termination units 21 and 22 to exchange copy frames with other wireless line termination unit and to abandon received frames. A communication path control unit 273 sets, in accordance with the monitoring result as to the state of the wireless lines by the radio monitoring unit 272, the line termination units 25 and 26 to each be an active system or a standby system. A switch core 271 passes frames to be transmitted to the line termination unit that operates as the active system.

Provided is a method of controlling a seven-axis articulated robot including seven joints sequentially arranged from a proximal end of the robot to a distal end of the robot, the seven joints including rotational axes each causing a next joint to turn and rotational axes each causing a next joint to pivot, such that the rotational axes causing turning and the rotational axes causing pivoting are arranged alternately, the seven-axis articulated robot being configured such that rotational axes of three proximal end side joints of the robot do not intersect with each other at one point. The method includes performing inverse transformation using, as a constraint condition, such a joint angle of a middle joint among the three joints as to cause an assumed elbow angle to be constant in a case where a rotational axis of the middle joint is assumed as a shoulder.

Provided is an electron microscope capable of enhancing a magnetic shield function even though the structure thereof has an objective tens that projects into a sample chamber space. The electron microscope includes: an objective lens (6) which focuses an electron beam to irradiate a sample (4) with; a sample chamber (5) which forms a sample space to contain the sample (4); a sample chamber magnetic shield (7) provided inside the sample chamber (5); and an objective lens magnetic shield (8) of a tubular shape which surrounds the periphery of the objective lens (6). A first and a second hole, which face to each other in a traveling direction of the electron beam, are provided in an upper plate (10) serving as an upper wall of the sample chamber (5) and in an upper shield (9) of the sample chamber magnetic shield (7). The objective lens (6) is held inside the first hole provided in the upper plate (10). A lower end of the objective lens (6) is disposed at a position lower than a lower end of the upper plate (10), and at a position of the second hole provided in the upper shield (9) or at a position near this position. The objective lens magnetic shield (8) is positioned inside the first hole, and a lower end thereof is connected to the upper shield (9).

An image processing device includes; a lesion candidate region detecting section that detects a lesion candidate region based on at least one color signal in a medical image including a plurality of color signals; an incidental region detecting section that detects an incidental region that arises because of incidental attributes accompanying a lesion from the medical image; and a detection standard changing section that changes a detection standard when detecting a lesion from the lesion candidate region in accordance with a detection result of the incidental region.
摘要:
A PFC converter that reduces a superimposed voltage generated by an inrush current into a filter capacitor operates such that, when a commercial alternating-current power supply is connected to input terminals of a PFC converter, a rectified voltage is applied to a filter capacitor via a diode bridge and a charging current flows through the filter capacitor. At the same time, the rectified voltage is also applied to a series circuit including a diode and a capacitor and a charging current for the capacitor flows through the series circuit. Accordingly, a charging time constant becomes large and a superimposed voltage generated by the inductance component of a line or a line filter connected to the line and the charging current becomes low.
