摘要:
The present invention is an apparatus for detecting a surface flaw in hot metal including a particularly designed television camera, a shutter means and a control circuit which compensates the television camera's shading as well as the temperature difference among normal parts of the observed material.The apparatus makes it possible to conduct clear detection of a flaw on the surface of the hot material as it is so that yield loss at the time of scarfing can be avoided while heat energy can effectively be utilized.

A method to inexpensively and efficiently produce conductive materials on the surface of which a nano-level fine structure is formed includes surface modification including immersing a stable anode electrode and a workpiece as a cathode electrode, the workpiece including a conductive material with a work surface, in an electrolytic solution, then applying a voltage not less than a first voltage and less than a second voltage between the stable anode electrode and the workpiece as the cathode electrode immersed in the electrolytic solution, thereby modifying the work surface, the first voltage being a voltage corresponding to a current value that is ½ of the sum of a first maximum current value appearing first in a positive voltage region and a first minimum current value appearing first in the positive voltage region with respect to voltage-current characteristics of a surface modification treatment system, the second voltage exhibiting a complete-state plasma.

There is provided a method for producing a surface-treated metallic material, by use of which a metallic material having a stable and excellent sliding characteristic can be produced with a low environmental load without covering the metallic material surface with an oxide film. The method for producing a surface-treated metallic material includes immersing an anode and a cathode in an electrolyte solution, placing a metallic material used as a material to be treated above the surface of the electrolyte solution, and applying a voltage between the anode and the cathode to treat the metallic material surface, the voltage being equal to or higher than a voltage for causing a complete plasma state.

A method for producing an optical member from a nanocomposite material which includes a thermoplastic resin containing inorganic fine particles is provided. The method includes: a first step of preparing in a solution the thermoplastic resin containing the inorganic fine particles; a second step of drying and solidifying the solution containing the prepared thermoplastic resin to produce the nanocomposite material having a specific surface area (surface area/volume) of 15 mm−1 or more; and a third step of heat-compressing the produced nanocomposite material to form the optical member in a desired shape.
摘要:
An electric actuator, which includes an exposed actuator terminal, for eliminating the need for insert molding and facilitating the manufacturing of a housing while preventing liquid from entering the housing. The actuator includes a motor. The housing is attached to the motor and includes an opening. A control circuit board accommodated in the housing controls the motor. An actuator terminal is arranged on the control circuit board and connected to an external terminal of an external connector through the opening. A terminal support arranged on the control circuit board supports the actuator terminal. A hollow fitting is attached to the terminal support and fitted into the opening so as to extend into the housing. A seal, arranged between the terminal support and the fitting, seals the housing.
