摘要:
A data transfer device is disclosed whereby both spoken conversation and transfer of data can easily and conveniently be carried out with a minimum of manual steps and repetitions operations. The disclosed device includes first telephone number memory for storing a telephone number of a remote communication node when the data transfer device originates a communication session; second telephone number memory for storing a telephone number of the remote communication node when the remote communication node originates the communication session; start command generating circuit for generating a start command; and data transfer circuit for transferring data. The above mentioned data transfer circuit is such that when the start command generating circuit generates a start command and the data transfer device has originated the communication session, the data transfer circuit initiates a connection over a channel for transmission of digital data between the data transfer device and the remote node corresponding to the telephone number stored in the first telephone number memory, and when the start command generating circuit generates a start command and the remote node has originated the communication session, the data transfer circuit Initiates a connection over a channel for transmission of digital data between the data transfer device and the remote node corresponding to the telephone number stored in the second telephone number memory.

摘要:
The use of a perforated plate anode in combination with a cation exchange membrane has been found to be extremely effective for rendering the current distribution in the cation exchange membrane uniform in practice of the ion exchange membrane process for the electrolysis of an aqueous solution of an alkali metal chloride. The uniform current distribution in the cation exchange membrane is, in turn, effective for preventing elevation of the electrolytic voltage and prolonging the life of the cation exchange membrane. Further, when the coating of the perforated plate anode on its front surface and the inner wall surfaces of the openings has a thickness larger than that of the coating on the back surface, the perforated plate anode has high durability and exhibits low electrolytic voltage for a long time as compared with the perforated plate anode having, on each surface, a uniform-thick coating.

A packing for use in a steel-pipe hydraulic testing apparatus, consisting of: an annular body having an annular cut in its inner peripheral portion; a plurality of backing pieces fastened to the wall of the annular cut at a given circumferential spacing and directed in the radial direction; and a plurality of adapter pieces embedded in the inner peripheral walls of the annular body of the packing at a given circumferential spacing and exposed to the annular cut, so that the aforesaid plurality of backing pieces may be each slidable on the surfaces of a pair of adjoining adapter pieces. This packing is contracted due to a hydraulic pressure being applied to the outer periphery of the body of the packing, and as a result the respective adapter pieces will slide on the surfaces of the adapter pieces in the circumferential direction of the packing.

Method and apparatus for non-destructive inspection of flaws in metal materials include exciting coils centered on a longitudinal axis of a cylindrical or columnar metallic material to be examined being arranged to surround the examinee material. A multiphase alternating current of such a relatively low frequency as to cause the exciting coils to generate a rotating magnetic field which rotates about the longitudinal axis of the examinee material is superimposed with a high frequency alternating current having an inspection frequency selected on the basis of the necessary sensitivity for detection of surface flaws of the examinee material. The composite multiphase current is applied to the exciting coils so that an electromagnetic effect induced in the surface of the examinee material by the high frequency alternating current is rotated for shifting circumferentially about the examinee material along with the rotating magnetic field. A detecting element group disposed in the proximity of the surface of the examined material detects the changing of the electromagnetic effect, dependent on the presence or absence of a surface flaw of the examinee material.

Disclosed is an apparatus for automatically processing an end portion of a tube disposed along a predetermined moving path so as to be movable toward and away from the moving path. A first clamping device is mounted on the base in front of the pointing device along the moving path. A tube press is disposed between the pointing device and the first clamping device for dimpling the tube wall to form axially spaced positioning sections thereon. A second clamping device is disposed between the tube press and the pointing device for clamping the end portion of the tube. A plug feeding device is disposed between the second clamping device and the pointing device for feeding a plug from a position out of the moving path to a position thereon. A plug inserting device includes an inserting nozzle movable in parallel to the moving direction of the tube for inserting the plug into the end portion of the tube. Lubricant is supplied into the tube through the inserting nozzle. The end portion of the tube is pointed by the pointing device.
摘要:
A liquid level detector for detecting whether a boundary surface between a liquid and a medium rises beyond a prescribed level comprises a rectangular prismatic refractor body formed of a material which only allows the transmission of a light having particular wavelengths and absorbs light having other wavelengths. The refractor body have first and second inclined flat surfaces and a base. The base of the refractor body is provided with a light-emitting element for projecting a beam of light having the particular wavelength and a photoelectric conversion element for converting the light to an electric signal. Each of these element is equidistantly spaced from the center of the base, and the optical axis of each of these elements defines an angle of 45.degree. with each of the inclined surfaces of the refractor body. Where the first inclined surface contacts an medium, the light beam from the light-emitting element passes through the refractor body, is totally reflected from the first and second inclined surfaces, and finally enters the photoelectric conversion element. Where the first inclined surface contacts a liquid, the light beam from the light-emitting element passes through the refractor body, is refracted on the first inclined surface and enters the liquid, and the photoelectric conversion element receives substantially no light and generates no electric signal.
