A forging method and forging apparatus able to improve a dimensional precision of a forged article and able to reduce the machining processes to a minimum and thereby reduce costs are provided. That is, a forging method placing a workpiece inside of a die, pressing the workpiece by a top part of the die in the axial direction toward the bottom part side of the die, and making the material of the end face of the workpiece flow to form the end face of the workpiece into a recessed/projecting shape, which forging method characterized by using independent pressing and holding means for pressing and holding the workpiece in the axial direction independent for the top part and the bottom part at the time of the press forming.

The present invention provides a gradually soluble coating film to be applied to instruments for waterworks. In a conventional polyvinyl alcohol solution not containing metal salt, there is formed a coating film in which polyvinyl alcohol molecules are piled up as shown in FIG. 2(a). In such coating film, water contacting with a surface thereof penetrates rapidly to the interface between the coating film and a base material, so that when water flows away, the coating film flows out and vanishes completely. On the other hand, in a coating film of the present invention, there are formed polyvinyl alcohol inclusion metal hydroxide clusters derived from the kind of metal in the solution as shown in FIG. 2(b). Although polyvinyl alcohol is dissolved or swollen to allow water to penetrate therein when water contacts with the coating film surface, the penetration speed of water in the direction of film thickness is controlled since the metal hydroxide clusters exist in the film. Therefore, when water flows away, only the film in a water penetrated portion in the vicinity of the coating film surface flows and the entire coating film does not vanish at one time.

An automotive seat of the type allowing a child seat to be mounted thereon and including a center back portion, wherein a shape-retaining/locking element is provided to a lower region of the center back portion. The shape-retaining/locking element includes a rigid hollow support body; a cut-away portion defined in the support body; a female engagement element to which the child seat is lockably engaged, the female engagement element being exposed outwardly in such cut-away portion; and a cover element for covering the hollow support body and cut-away portion. The cover element includes a layer of hard synthetic resin material with a certain elasticity, such that it normally tends to retain its original shape generally conforming to a forwardly facing surface portion hollow support body. One end of the cover element may be releasably connected to the lower region of the hollow support body.

The image printing system is capable of properly defining amount of ink without adjusting ink clearance. The image printing system includes an offset printing machine, in which proper amount of ink is supplied to a plate drum via an ink fountain roller on the basis of image data. A memory stores the image data of an original image and an ink amount table, in which rotational speed data of the ink fountain roller correspond to rate of area of picture in the original image. A control unit calculates the rate of area of picture on the basis of the image data, reads the rotational speed of the ink fountain roller from the ink amount table on the basis of the rate of area of the picture, corrects the rotational speed so as to define proper control data for rotating the ink fountain roller, and sends the proper control data to the offset printing machine so as to control the amount of ink to be supplied to the plate drum.

Organic electroluminescent devices having a luminescent material-containing layer interposed between a positive electrode and a negative electrode and designed to supply an electrical energy to the luminescent material that emits light upon receipt of the energy. The negative electrode contains f and p elements. The f is at least one element selected from those having electronegativity values higher than that of calcium, and, equal to or lower than that of vanadium. The p is at least one element selected from those having electronegativity values equal to or higher than that of aluminum. The negative electrode may further contain d element, if necessary. The d is at least one element selected from those having electronegativity values equal to or higher than any of those of iron, cobalt and nickel, and, equal to or lower than that of gold.
