Highly reliable measurement of degree of alloying of galvannealed steel sheets is carried out in order to fully control the continuous hot-dip galvanizing and galvannealing process on the basis of evaluation of a combination of two or more X-ray diffraction characteristics. Exact degree of alloying can be estimated without regard to fluctuations in the particulars of the material, the process conditions and the type of the product obtained.

A process for the partial hot dipping of a long steel strip is disclosed which comprises forming an oxidation-inhibiting film, oxygen-impermeable and thermally stable in a hot-dipping bath, which film is produced by the chemical reaction of an iron content in the steel strip with an oxidation inhibiting film-forming agent, such as an inorganic phosphoric acid compound, on a predetermined area of the steel strip surface, forming, as required, an intermediate layer comprising an inorganic binder, such as water glass, on the resulting film, forming a carbon-containing, plateing-stopping film as a top coat on the intermediate layer, and hot dipping the steel strip.

A rotating connector in which a sliding cap is closely interposed between rotational sliding portions of a first housing and a second housing that are rotatably coupled to each other. A flexible cable is wound in a reverse direction through a turned-back portion in an annular storage portion defined between the first and second housings. Transverse end portions of this flexible cable face a flange portion formed on the sliding cap. Moreover, the transverse end portions of the flexible cable face a curved portion. Furthermore, the annular storage portion is defined between an outer cylindrical portion of the first housing and an inner cylindrical portion of the second housing. A movable body, in which a plurality of rollers are rotatably mounted on pins between a pair of holders, is placed in this storage portion. Further, the turned-back portion of the flexible cable wound in a reverse direction through the movable body is looped around one of the rollers. An inward extension portion inwardly projecting from the roller is formed on the holder. This inward extension portion is axially supported on the inner cylindrical portion. Moreover, the bottom transverse end portion of the flexible cable faces the inward extension portion.

An imaging apparatus includes the functions of conducting automatic exposure control and of conducting shake correction with respect to digital image data acquired by an image pickup unit. The imaging apparatus includes: a determining unit that determines whether or not the shake correction is being implemented; and a switching unit which, when it has been determined by the determining unit that the shake correction is being implemented, switches the shutter speed such that the shutter speed is raised in comparison to when it has been determined by the determining unit that the shake correction is not being implemented. An imaging method determines whether or not the shake correction is being implemented, and when it has been determined that the shake correction is being implemented, switches the shutter speed such that the shutter speed is raised in comparison to when it has been determined that the shake correction is not being implemented.

A method of making a power transmission belt/belt sleeve, which method includes the step of providing a first mold assembly having a central axis and a circumference, providing a sheet material having first and second oppositely facing surfaces, placing the sheet material around the first mold assembly and causing a contoured portion of the first surface to be keyed to the first mold assembly so that the sheet material is in a predetermined circumferential position relative to the first mold assembly, providing a second mold assembly having a contoured surface, placing the contoured surface of the second mold assembly against the second surface of the sheet material, providing a guide element, operatively connecting the guide element between the first and second mold assemblies so that the guide element maintains the second mold assembly in a predetermined circumferential position relative to the first mold assembly, and forming the second surface of the sheet material through the contoured surface of the second mold assembly with the first and second mold assemblies and sheet material in an operative relationship. The contoured portion of the first surface of the sheet material can be pre-formed or formed in place on the first mold assembly.
摘要:
A rotary connector which prevents separation of a resilient tongue from a flexible cable so as to prevent buckling. The rotary connector includes first and second housings rotatably connected together and forming an annular space therebetween. A flexible cable and a movable member are received in the annular space. The movable member includes a turntable having a stationary cylinder and a reversing roller, the stationary cylinder including a guide projection. The flexible cable is wound in opposite directions on opposite sides of the movable member and includes a U-shaped reverse portion extending through a gap between the stationary cylinder and the reversing roller. A resilient tongue having a free end portion substantially formed in a linear shape in an unloaded condition is affixed to an inner surface of the flexible cable and to an inner cylinder portion of the second housing. An amount of deformation of the free end portion when it is bent between the stationary cylinder and the reversing roller can be reduced, thereby preventing separation of the tip of the resilient tongue from the flexible cable.
