The present invention provides a caulked assembly to be manufactured at low cost, and maintain sufficient caulking strength, and the manufacturing method and apparatus thereof. The manufacturing method comprises steps of forming a mounting hole for inserting and assembling a columnar body in a metal plate body, and forming a thick part along an inner circumferential edge of a mounting hole; forming a circumferential groove with a predetermined depth at an assembled position of a outer circumferential surface of the columnar body inserted into the mounting hole; inserting the columnar body into the mounting hole to set to the assembled position where the thick part is opposed to the circumferential groove; and caulking for compressively pressing the thick part from an axial direction of the columnar body to plastically deform the thick part in a center direction of the mounting hole to bite the thick part into the circumferential groove.

A superconducting magnet includes: first and second torus coolant containers substantially symmetrically, vertically arranged to have a space and a symmetrical plane therebetween for storing a coolant. Each of the first and second torus coolant containers includes therein a main coil bobbin with a main coil for generating a measurement magnetic field, a shield coil bobbin with a shield coil for generating a shielding magnetic field for suppressing outside leak of the measurement magnetic field, a plate member vertically reinforced at a plane thereof opposite to a plane thereof facing the symmetrical plane for supporting the shield coil bobbin and the main coil bobbin. The main coil bobbin is further supported by the shield coil bobbin, to cause the main coil to generate the measurement magnetic field having a substantially uniform magnetic field intensity at a middle region of the space. A magnetic resonance imaging apparatus using the superconducting magnet is also disclosed.

A semiconductor pellet and chip components are provided on an insulating substrate, and are sealed with a molding resin that is molded by transfer molding. The chip components are positioned so as to surround the semiconductor pellet on all four sides. The lengthwise directions of the chip components surrounding the semiconductor pellet are aligned in a uniform direction. The insulating substrate is set within a die molding apparatus so that during resin injection, the lengthwise directions of the chip components are aligned substantially perpendicularly to the direction of flow of the injected resin.

An image forming apparatus has a transfer attitude correcting section for correcting a transfer attitude of the transfer sheet to receive the toner image and for conveying the corrected transfer sheet to the transfer section with a timing to match with the movement of the toner image. The transfer attitude correcting section includes a roller unit including a base board rotatable around a center of rotation and a registration roller mounted on the base board, a detecting section for detecting a position of the transfer sheet being conveyed by the registration roller; and a control section for control the roller unit based on detection data detected by the detecting section so as to correct a skew of the transfer sheet by rotating the base board and to correct a deviation of a transfer position of the transfer sheet by shifting the registration roller on the base board.

This invention provides a printed wiring board having an intensified drop impact resistance of a joint portion between pad and solder. An electrode pad comprises pad portion loaded with solder ball and a cylindrical portion projecting to the solder ball supporting the pad portion. An outer edge of the pad portion extends sideway from a cylindrical portion so that the outer edge is capable of bending. If the outer edge bends when stress is applied to the solder ball 30, stress on the outer edge of the pad portion on which stress is concentrated can be relaxed so as to intensify the joint strength between an electrode pad and solder ball.
