Abstract: A recording medium and server provide a game that improves the interest in and taste of a battle event and increases the interest in and real enjoyment of the entire game. The recording medium provides a game including a predetermined battle event comprising at least one battle. In a battle event of this game, game contents are displayed in a first field, and a player selects therefrom a game content to be used for a battle with an enemy character. The first field is replenished with another game content alternative to the selected game content as needed so that the player can further select an additional game content therefrom.

Abstract: There are provided a positioning method and a positioning device that can position workpieces by a simple method and configuration. A positioning method includes: gripping at least one of first and second workpieces; obtaining point group data of the at least one gripped workpiece of the first and second workpieces; calculating a translation matrix of shape fitting point group data obtained by adjusting a position of the point group data to reference data in a position adjustment state of the first and second workpieces; calculating an inverse matrix based on the translation matrix; and positioning the first and second workpieces by moving the at least one gripped workpiece of the first and second workpieces based on at least one of the translation matrix and the inverse matrix.

Abstract: Provided is a stator core formed by laminating electrical steel sheets to steadily curtail iron loss and a motor equipped with the stator core. A stator core 10 formed by laminating electrical steel sheets 11 having a thickness of from 25 to 80 ?m steadily curtails iron loss. A motor 20 including the stator core 10 formed by laminating electrical steel sheets 11 having a thickness of from 25 to 80 ?m has a steadily improved efficiency.

Abstract: Provided is a method of manufacturing a laminated core for stably fixing a thin core piece while suppressing reduction in production efficiency, and an inner core and an outer core with core pieces stably fixed. A method of manufacturing a laminated core for manufacturing an inner core 10 includes: a step A of laminating a plurality of core pieces 11 and temporarily fixing each of the core pieces to another core piece 11 to obtain a core piece group 16; a step B of fitting the core piece group 16 to a holder 17; a step C of applying an uncured curable resin P to an outer peripheral region of the core piece group 16; and a step D of curing the curable resin P applied to the core piece group 16 and fully fixing each of the core pieces 11 to another core piece 11.

Abstract: A coil spring manufacturing device includes a mandrel around which a wire is wound, a feed mechanism which feeds the wire toward the mandrel, guide members which guide the wire, a chuck which fixes a distal end of the wire, and a clamp mechanism. The clamp mechanism sandwiches the wire from both sides before the distal end of the wire reaches the mandrel. Further, the clamp mechanism can be rotated about a fulcrum by rotation actuator, and can also be slid in a direction along an axis of the mandrel by sliding actuator. In a state in which the wire is sandwiched by the clamp mechanism, the clamp mechanism is rotated, and if necessary, is slid. Thereby, a bent portion for a negative pitch portion of a coil spring is formed at a part of the wire.

Abstract: To enable issuance of an electronic receipt without previously registering personal information and carrying out a special operation in execution of a payment by a customer.

Abstract: A cylindrical case main body, and a connecting ring body fitted and fixed to a first end of the case main body and having an annular groove open in the centrifugal direction, are provided. The connecting ring body has a notch open to a side opposite to a second end of the case main body. Into the notch of the connecting ring body, a reinforcement body is fitted, and the reinforcement body has an arc-shaped groove continuing to the annular groove of the connecting ring body in a state where the reinforcement body is fitted into the notch of the connecting ring body. In addition to attaining high rigidity, reduction in weight and reduction in manufacturing cost can also be achieved.

Abstract: A cylindrical case body made of a composite material; a linking ring made of aluminum, fitted and fixed to a rear end portion of the case body and having an annular groove which receives a reverse thrust load from a reverse thrust transmission body; and ring constituent bodies made of titanium alloy, each of which is placed in the rear end portion of the case body and has an arcuate groove which undertakes a reverse thrust load larger than that received by the linking ring, are provided in a fan case. The ring constituent bodies are fitted in notches of the linking ring and are brought into contact with outward receiving walls of the linking ring. The ring constituent bodies are positioned relative to the case body in the axis direction and in the radial direction, and the annular groove and the arcuate grooves continue to each other.
