Abstract: The present invention achieves a force sensor in which an electrode, element, and/or the like connected to a strain gauge can be suitably attached to a strain element. The force sensor includes: a strain element including an arm portion that is deformable under an external force; and a strain gauge attached to the arm portion. The strain element includes a projection that sticks out from the arm portion in a direction intersecting the longitudinal direction of the arm portion.

Abstract: Provided is a thermoacoustic refrigerator including an air column pipe, a prime mover, a load, and a heat accumulation tank. An exhaust gas supplied to and discharged from the heat accumulation tank is supplied, as a heat source, to the prime mover disposed inside the air column pipe, so as to cause self-oscillation of a working gas filled in the air column pipe so that sound waves are generated. With the sound waves, the load disposed inside the air column pipe converts sound wave energy into heat energy, so as to output cold heat.

Abstract: A shot processing apparatus is equipped with a work set jig, a hanger transport device, a projection machine, a projection positioning unit and a clamp unit. The work set jig is equipped with a base member including an upper and lower pair of cross members and a vertical member. A workpiece is settable at the base member between the upper and lower pair of cross members. The hanger transport device is, with the work set jig in a hanging state, movable along a guide path in the shot processing apparatus and is capable of stopping thereon. The projection machine projects projection media at a workpiece set at the base member inside a projection chamber which the workpiece is conveyed into. The projection positioning unit positions the work set jig at a stopping position in the projection chamber. The clamp unit fixes a workpiece between the upper and lower pair of cross members.

Abstract: An object is to accurately estimate loss-on-ignition in a short time. A loss-on-ignition estimation apparatus includes at least one processor configured to carry out an estimation step, the estimation step including estimating the loss-on-ignition of foundry sand with use of a learned model constructed by means of machine learning. The learned model is configured to receive, as input, (1) sand weight data relating to a weight of the foundry sand detected in a calcination period and (2) at least one of (i) sand property data relating to one or more properties of the foundry sand, (ii) additive data relating to one or more additives added to the foundry sand, and (iii) calcination environment data relating to a calcination environment detected in the calcination period. The learned model is configured to generate, as output, an estimated loss-on-ignition of the foundry sand.

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. Based on a preset target value of weight of sand, a control section (18) controls the driving mechanism (40) so as to decrease an amount of overlap of the opening portion (34) of the gate (30) and the lower end opening (24A) of the hopper (20) in a stepwise manner in accordance with an increase in the weight of the sand measured by a scale.

Abstract: Providing a method for reducing occurrences of a mold shift of a cope and a drag that have been molded by a flaskless molding machine and have been assembled by estimating a cause of a mold shift based on measurements and by taking appropriate measures, and a flaskless molding line that uses the method. The method for reducing occurrences of a mold shift of a cope and a drag (1, 2) that have been molded by a flaskless molding machine (200) and have been assembled comprises a step of measuring specific data at positions where a mold shift may occur during a process for manufacturing or taking out the cope and the drag, and a step of determining if the obtained specific data are within an allowable range.

Abstract: An ultrasonic inspection apparatus includes: an acquisition unit acquiring a signal indicating a fundamental wave and a second harmonic of an ultrasonic wave, which are obtained by the ultrasonic wave being scanned over an inspection object through a medium, at each scanning position; a calculation unit calculating a value obtained by dividing a second harmonic amplitude by a square of a fundamental wave amplitude, at each scanning position; and an output unit outputting information on a defect of the inspection object, based on the value obtained by dividing the second harmonic amplitude by the square of the fundamental wave amplitude.
