A welding gun driving device is provided with an electric motor, a feed screw mechanism, and a pressure rod axially moved forward and backward via the feed screw mechanism by the electric motor. A rotor of the electric motor is formed into a hollow shape through which the pressure rod is insertable. The feed screw mechanism is provided with a screw shaft fixed to the rotor concentrically with the rotor, and a nut portion screwed to the screw shaft. The pressure rod is provided with the nut portion and a hollow rod portion extending toward the axial front from the nut portion. The rotor is provided, at its inner peripheral face, with a guide portion through which the pressure rod is inserted and supported so as to be relatively rotatable and axially slidable.

There is provided a backflow preventing mouth plug comprising an elastic membrane element having a discharge opening for discharging fluid and mounted to a mouth part of a container and a plug member disposed in the elastic membrane element to prevent unintentional outflow of the fluid. The plug member has a spherical seal surface with which the elastic membrane element elastically and closely contacts. At least one thick wall portion and at least one thin wall portion are alternately formed around the discharge opening of the elastic membrane element in a circumferential direction thereof.

A microwave sending antenna 3R and a microwave receiving antenna 4R are provided to a right-side furnace wall 1R, and the system is devised so that the microwaves emitted from the microwave sending antenna 3R are reflected by the right-side edge of a cold-rolled steel plate 2, and the reflected waves are received by the microwave receiving antenna 4R. Similarly, a microwave sending antenna 3L and a microwave receiving antenna 4L are provided to a left-side furnace wall 1L, and the system is devised so that the microwaves emitted from the microwave sending antenna 3L are reflected by the left-side edge of the cold-rolled steel plate 2, and the reflected waves are received by the microwave receiving antenna 4L. If the time from the sending of the microwaves until the receiving of the reflected waves is designated as t, and the velocity of the microwaves is designated as c, then the distance to the object reflecting the microwaves is determined from t·c/2. It is possible to provide a method for measuring the width-direction end position of a material strip with which noise and atmosphere have little effect, installation is easy, and there is little mechanical interference with the material strip.

A method of concentrating a gaseous substance includes the steps of isolating a trap in which an analyte to be concentrated has been absorbed from a carrier gas passed through the trap and reducing the pressure within the trap to a first pressure. The analyte is desorbed from the trap and the analyte released from the trap is diffused into an analyser operating at a second pressure lower than the first pressure.

When an image processing apparatus having a binarizing unit for binarizing by a hardware process allows an image signal received from an electronic equipment having a binarizing unit for binarizing by a software process to be printed from a predetermined printer, it is an object to efficiently convert a multivalue image signal to a binary image signal and to print. To accomplish this object, either one of a mode to transmit the multivalue image signal to the image processing apparatus and a mode to binarize the multivalue image signal by the electronic equipment and, after that, transmit the binary image signal to the image processing apparatus is selected. In accordance with the selection result, the multivalue image signal or the binary image signal binarized by the electronic equipment is transmitted to the image processing apparatus.
