Abstract: Disclosed is a gaming machine. The gaming machine determines a priority attraction-in ranking depending on an internal winning combination and a type of a symbol, for each of the symbols arranged on the reels, compares the priority attraction-in rankings related to each of the symbols ranging from a symbol located at a predetermined position to symbols within a predetermined range, when the stop operation is detected, and stops rotation of the reels when a symbol having the highest priority attraction-in ranking reaches the predetermined position.

Abstract: The invention provides a technique for evaluation of a spot welded portion by which the strength of a panel. In the evaluation method, a stress value at a welded portion of the panel is calculated by a stress analysis according to a FEM using the elements, and then the strength of the welded portion is evaluated based on the stress value at the welded portion. Particularly, a portion in the proximity of the spot welded portion is divided, with a central portion of the spot welded portion registered with a nodal point of the elements, into a central element and a plurality of concentric ring-like elements including first and second ring-like elements from the center side provided by the central portion of the spot welded portion. Thereafter, the plural concentric ring-like elements are individually divided in a circumferential direction each into a plurality of portions to form the elements. Then, the strength is evaluated based on the stress value of the second ring-like element.

Abstract: An electromagnet (A) capable of being used for a solenoid valve. In this electromagnet (A), a pipe unit (6) is provided at one end part thereof with a mounting portion (12) opposed to a valve body (B), and a cap (E) is joined to the other end part thereof. The pipe unit (6) is provided therein with a movable core (24) so that the core (24) can be moved forward and backward therein, and a coil unit (D) is fitted around the outer circumferential surface of the pipe unit (6). The cap (E) and pipe unit (6) are combined with each other by the threads (18, 39) formed in and on the opposed inner and outer circumferential surfaces thereof. In order to fasten the electromagnet (A) to the valve body (B), the pipe unit (6) is connected to the valve body (B), and the coil unit (D) is then fitted around this pipe unit (6), the cap (E) being then screwed to the pipe unit (6). Thus, the coil unit (D) can be set firmly by the cap (E).
