A multilayered structure which includes insulating layers and electrode layers and can be easily arrayed. The multilayered structure is manufactured by using a substrate on which first and second groups of columnar structures are arranged in a predetermined arrangement, and includes: a first electrode layer formed by forming a film of a conducting material on the substrate or an insulating layer except for portions around the first group of columnar structures; an insulating layer formed by spraying powder of an insulating material on the first electrode layer to deposit the powder thereon; a second electrode layer formed by forming a film of a conducting material on the insulating layer except for portions around the second group of columnar structures; and interconnections formed by filing, with a conducting material, holes formed by removing the columnar structures from the substrate.

A metal casting fabrication method is provided. In accordance with the method, first a metal plate is disposed in the cavity of molding dies. This metal plate includes a first surface formed with a heat insulating layer, and a second surface opposite to the first surface. With the metal plate placed in the cavity, the heat insulating layer is held in contact with the dies, while the opposite or second surface is partially exposed to the cavity. The injected molten metal properly fills the cavity from end to end since its heat is not conducted unduly to the dies via the metal plate.

A pillow type packaging apparatus has a suction belt for conveying flexible continuous sheet material. A guide unit guides the continuous sheet material being conveyed, and forms the continuous sheet material into a quadrangular tube in which a pair of its longitudinal edges are confronted with each other. A center sealer thermally seals up the longitudinal edges. An inserter inserts an article into the tube through the guide unit. The tube is formed into a packaging bag by cutting and sealing. In the guide unit, an inner guide frame is inside an outer guide frame. The outer guide frame includes first to fourth corner portions, which are disposed in a quadrangular shape, have inside edges in contact with the continuous sheet material, and shape the continuous sheet material into the tube. The first to fourth corner portions are movable in directions of width and height of the continuous sheet material. The tube is changeable in size. The inner guide frame includes fifth to eighth corner portions, which respectively correspond to the first to fourth corner portions, are disposed in a quadrangular shape, contact the continuous sheet material, and maintain the continuous sheet material shaped in the tube inside the first to fourth corner portions. The fifth to eighth corner portions are movable in the directions of the width and height with respective distances therefrom to the first to fourth corner portions kept unchanged.

A turret punch press includes rotatable upper and lower turrets, a striker which is vertically movable for striking a punch, a plate positioning device for moving and positioning, in the X and Y directions, a plate workpiece supported on a work table, and a tool changing device, wherein a punch holder magazine and a die holder magazine supporting respectively a punch and a die to be installed on the upper turret and the lower turret to replace the punch and die in use, are provided adjacent to the upper and lower turrets. The punch changing position on the upper turret is below the punch holder magazine, and the die changing position on the lower turret is above the die holder magazine. The tool changing device is positioned on a vertical line between the punch and die changing positions so that the punches and dies can be changed by a direct linear operation.

Provided is a tire defect detection method capable of accurately detecting a thinly extending convex defect of a tire surface. Prior to the start of Step S1, two-dimensional images including a slit light image are successively obtained in advance. In Step S1, a slit light image is extracted from data of a plurality of shot two-dimensional images. In Step S2, an eccentricity component which is deviation resulting from eccentricity is eliminated from the extracted slit light image. In Step S3, a feature quantity is calculated based on the light image from which the eccentricity component is eliminated, and in Step S4, a thinly extending convex defect is detected based on the calculated feature quantity.
