Filed: 1985-01-18
Abstract: PURPOSE:To contrive improvement in the corrosion-resisting property of the titled magnet by a method wherein a corrsion-resisting thin film layer is formed by coating on the surface of the permanent magnet body mainly composed of the specific compositional range of the rare-earth containing Y, boron and iron by performing a sputtering method. CONSTITUTION:The argon gas or reactive gas introduced into a vacuum chamber is discharged using a sputtering power source, coating atoms are discharged by colliding ionized gas with a target plate, and a corrosion-resisting thin film layer is formed by coating on the surface of the permanent magnet body, having the main phase consisting of tetragonal phase, mainly composed of a Y-contained rare-earth element B, and Fe to be arranged in the chamber. In this case, as the crystal structure of the rare-earth element containing Y is turned to the cubic constitution of the same structure as an alpha-iron, high coercive force is not obtained, and residual magnetic flux density is reduced when 30atom% is exceeded. B is turned to a diamond-faced body constitution with 2atom% or below, high coercive force is not obtained, and the residual magnetic flux density (Br) is reduced when 28atom% is exceeded. In the case of Fe, the residual magnetic flux density is reduced with 42atom% or below, and high coercive force is not obtained when 90atom% is exceeded.

The part 3 codes the synchronous signal and the section of picture information that are divided equally and sends them to the modulating part 4. The modulated signal is transmitted to the transmission line 7 from the transmission network control unit 5. The part 4 gives a coding to the presence or absence of the picture information within a block to turn it into a control signal, and also gives a coding to the total number of the blocks having information or no information to turn it into a check signal. Thus a condensation is given to the facsimile signal and at the same time the detection is facilitated for the synchronous signal. In such a way, a detection is made possible for an error.

Abstract: PURPOSE:To focus charged beams having different acceleration voltage on the same position at small incident angles while minutely stopping down by using focusing lenses, which respectively focus the respective charged beams, deflectors, which respectively deflect the charged beam directions and one common lens. CONSTITUTION:When impressing the same reference acceleration voltage on the charged beam sources 41-1 and 41-2, the radiated charged beams 51-1 and 51-2 are focused into the parallel beams through the lenses 31-1 and 31-2 for being incident on a common lens 11.

Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To easily identify a colliding automobile by embedding a wire propagating ultrasonic wave at a part facing to a road at the end of a tunnel and taking the photograph of the automobile by actuating a camera when the wire is cut off because of the collision of the automobile. SOLUTION: When the automobile collides against the tunnel and the tunnel is broken, the wire 5 embedded in the construction member of the tunnel is cut off. Then, the reflected wave of the ultrasonic wave is generated from the disconnection part A of the wire 5. The reflected wave of the ultrasonic wave is detected by an ultrasonic sensor 8 and detection output is given to a current amplifier 9. Thus, a contactor 10 is actuated and an always-open contact 11 is closed. By closing the contact 11, the camera 6 is actuated for a specified time to take the photograph of the automobile colliding against the tunnel from a rear side. Thus, the colliding automobile is easily and accurately identified in the circumstances that the automobile collides against the upper part or the side wall of the tunnel and damages the tunnel by disregarding the hight restriction of the tunnel.
