Abstract: A stator includes a main yoke having a cylindrical shape with a bottom, an auxiliary yoke having a band shape arranged on an outer or inner circumferential wall surface of this main yoke, and a field magnet arranged inside the main yoke. The auxiliary yoke is arranged along a circumferential direction on the outer or inner circumferential wall surface of the main yoke. One end of the auxiliary yoke has at least one protrusion, and another end of the auxiliary yoke has at least one recess facing and engaging in a circumferential direction with the protrusion either on the inner or outer circumferential wall surface of the main yoke.

Abstract: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).

Abstract: An opening portion that is formed so as to pass-through an opening/closing plate portion of a gate, can be disposed at a region overlapping a lower end opening of a hopper. The opening portion is structured by a first pass-through portion, and a second pass-through portion that is formed so as to be continuous with the first pass-through portion. A width, in a direction orthogonal to a lined-up direction in which the first pass-through portion and the second pass-through portion are lined up, is narrower than the first pass-through portion. Further, a driving mechanism moves the gate such that the opening/closing plate portion moves in the lined-up direction as seen in a plan view. Based on a preset target value of weight of sand, a control section controls the driving mechanism so as to decrease an amount of overlap of the opening portion of the gate and the lower end opening of the hopper in a stepwise manner in accordance with an increase in the weight of the sand measured by a scale.

Abstract: An opening portion (34) that is formed so as to pass-through an opening/closing plate portion (32) of a gate (30), can be disposed at a region overlapping a lower end opening (24A) of a hopper (20). The opening portion (34) is structured by a first pass-through portion (34A), and a second pass-through portion (34B) that is formed so as to be continuous with the first pass-through portion (34A). A width, in a direction orthogonal to a lined-up direction in which the first pass-through portion (34A) and the second pass-through portion (34B) are lined up, is narrower than the first pass-through portion (34A). Further, a driving mechanism (40) moves the gate (30) such that the opening/closing plate portion (32) moves in the lined-up direction as seen in a plan view.

Abstract: When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position of the pressing member at the pressing start time is identified. As a result, the pressing start time and the pressing starting position of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.

Abstract: In a construction wherein at the start of fixing, a pressure belt is brought into contact with a fixing roller at uniform timing, it has sometimes been the case that the temperature of the pressure belt at a point of time whereat the fixing is started does not become a desired temperature but faulty fixing occurs. The timing for bringing the pressure belt into contact with the fixing roller at the start of fixing is changed in accordance with the detected temperature of the pressure belt. By such a construction, faulty fixing can be prevented from occurring.

Abstract: An image forming apparatus which enables easy management of proofs in a printing process. An image forming apparatus 299 is provided with a reader unit 50, a transfer charger 220, color sensors 274-1 to 274-4, a printer controlling unit 21. The reader unit 50 inputs image data for forming an image on a sheet having an RFID tag 701. The transfer charger 220 generates a transfer image for forming the image on the sheet based on the inputted image data. The color sensors 274-1 to 274-4 measure image formation conditions of the transfer image. The printer controlling unit 21 writes the measured image formation conditions into the RFID tag 701.
