The present invention provides an electric locking device which has a simple structure, with which an operating time can be saved, and which has a sufficient clamping force required for operation. To a camshaft coupled to an electric motor through a speed reducing mechanism, a first cam and a second cam conjugate with each other are coupled. The first cam drives an arm driving rod in a clamping direction and the second cam drives the arm driving rod in a returning direction. Rotational motions of the first and second cams are converted into linear motions in the same direction by first and second cam contacting members supported by the arm driving rod. The arm driving rod drives a clamping arm to cause the arm to carry out a clamping operation. A cam face is provided as to move the clamping arm at a high speed until the arm reaches a vicinity of an end and to move the arm at a lower speed after the arm has reached the vicinity of the end.

In an image forming device, on a farther end side from each paper guide of a manual paper feed tray, a pair of protruding portions are arranged such that each of the protruding portions is arranged on either side to prevent oblique movement of papers. One of the protruding portions is provided with a paper setting dial rotatably attached thereto. Marks indicating a paper size are displayed on a circumferential surface of the dial such that the size can be set by turning the dial in accordance with the size of the placed paper. The paper setting dial is attached on a side on which a user stands when placing the papers.

The invention discloses an indoor direct current fast grounding switch. The switch includes a shell, and a connecting terminal, an electrical control, a signal output, an operating mechanism, a manualoperation, an electric operation module and stationary-moving contacts which are arranged in the shell; the inner cavity of the shell is divided into front and rear cavities through a vertical plate;the stationary-moving contacts are installed in the rear cavity and divided into four copper bars which are in symmetric arrangement through a manner of upper and lower rows and extend to the rear wall of the shell; one of the two upper copper bars is connected to the negative electrode of a direct current power supply system, and the other one is grounded with PE; mechanical connection is arranged between the two lower copper bars to perform common action and are electrically connected to each other through inter-phase short circuit copper bars; in the front cavity, a connecting terminal module is installed on the top, electrical control and signal output modules are parallelly distributed at the middle part, and operating mechanism, manual operation and electric operation modules are distributed at the lower part; the operating mechanism module, except for controlling the two moving contacts, is also connected to the manual operation, electric operation, signal output and electricalcontrol modules; and the electric operation module is also connected to the connecting terminal module. The switch is enclosed, compact in structure, small in volume and reliable in performance.

The invention provides a method for restoring the volume of the non-woven fabric which can effectively heat the non-woven fabric with a heated fluid and recover the volume of the non-woven fabric reliably and stably. In the inner space (9) of the heating chamber (8) of the heating device (3) for heating the non-woven fabric (2) containing the thermoplastic fiber during transportation, and from When the inlet (9a) side of the nonwoven fabric (2) in the inner space (9) of the heating chamber (8) blows fluid to the nonwoven fabric (2) in the inner space (9) of the heating chamber (8) , blowing the above-mentioned fluid into the inner space (9) of the heating chamber (8) at a flow rate faster than the conveying speed of the above-mentioned non-woven fabric (2), and at a temperature greater than or equal to 50°C lower than the melting point of the thermoplastic fiber and less than this The nonwoven fabric ( 2 ) is heated for 0.2 seconds to 4 seconds at the temperature of the melting point.

A method is described for determining the size of a transparent particle (2), wherein the particle (2) is illuminated with light from a light source (6), wherein using a radiation detector (7) a time-resolved intensity curve of light from the light source (6) scattered on the particle (2) is measured at a preselectable scattering angle θs, wherein characteristic scattered light peaks are determined in the intensity curve, and wherein the size of the particle (2) is determined on the basis of the time difference between two scattered light peaks, characterized in that, with the help of two radiation detectors (7) or light sources (6), a first and a second time-resolved intensity curve of scattered light, scattered on the particle (2) in the forward direction, are measured; a transmission peak (12) and a reflection peak (11) are determined from the first intensity curve and from the second intensity curve; a first time difference between the transmission peaks (12) is determined, and a second time difference between the reflection peaks (11) is determined; a characteristic variable α is determined from the ratio of the first time difference and the second time difference; and a size determination is performed for the particles (2) for which the characteristic variable α corresponds to a preselectable value.
