Abstract: An information processing device including at least one processor, wherein the processor is configured to: acquire positional information indicating a position of a compression member, which is configured to be movable in a plane direction of a contact surface with a breast, in the plane direction in a mammography apparatus that irradiates the breast compressed by the compression member with radiation to capture a radiographic image; and perform control to direct an image projection unit, which projects a projection image onto a projection surface of the compression member, to project the projection image onto the projection surface of the compression member whose position has been specified on the basis of the positional information.

Abstract: A control device including: at least one processor, wherein the processor is configured control an image projection unit which projects a projection image onto a projection surface of a compression member and an irradiation field projection unit which projects a range of an irradiation field of radiation using visible light in a mammography apparatus which irradiates a breast compressed by the compression member with the radiation to capture a radiographic image such that projection of the projection image and projection of the range of the irradiation field are switched.

Abstract: A control device including: at least one processor that is configured to detect whether or not compression of a breast by a compression member in a mammography apparatus is completed and perform control to direct an image projection unit, which projects a projection image onto a projection surface of the compression member, to stop the projection of the projection image onto the projection surface in a case in which it is detected that the compression is completed.

Abstract: A compression member which compresses a breast placed between a radiation source and a radiation detector, wherein at least a partial region of at least one surface of the compression member that does not come into contact with the breast is roughened. A support member and a mammography apparatus are also provided.

Abstract: An air massage device which allows for a uniform massage treatment upon a human body. This is accomplished by having a person lie upon an air-mat divided into three distinct sections, with each section corresponding to either the upper, middle or lower region of the human body. Within the upper and middle sections are a plurality of air-bags which can be inflated and deflated independently of each other. In order to massage one of the regions of the human body lying upon the mat, the air-bags within one of the mat sections are inflated and deflated in such a sequence that an inflation/deflation frequency of all the air-bags contained within that section of the air-mat will be equal over any set period of time. In this manner, a uniform massage is assured as each air-bag within the section will inflate and deflate an equal number of times.

Abstract: A reclining legless chair comprising an interlocking headrest constructed from a framework composed of a seat frame, back materials, and a headrest frame, which allows users to automatically set the inclining angle of the headrest which is interlocked to the angle between the seat and the back of the chair wherein the latter angle can be set in one of several steps at will by a user. The framework is made from a U-shaped seat frame, back materials and a headrest frame, in which both opening ends of the seat frame are connected to the straight rods of the back materials through a ratchet and the other ends of the rods are connected to both ends of a U-shaped headrest frame through interlocking mechanisms. The framework is suitably covered with elastic materials, is finished by covering the elastic materials with external cloth and permits the headrest frame to move interlockingly with the inclining angle of the back materials against the seat frame.

Abstract: A chair-type polyfunctional automatic massager which can be used selectively for either a rubbing motion or a finger pressing motion, is driven by one motor and can provide 5 different kinds of movements selectively at will by making the starter apparatus installed in the back of a chair raise and lower. The massager is made up of a driving mechanism which can independently rotate two kinds of driven shafts depending on the direction of rotation of a main spindle rotated by a starter motor. A driven shaft is attached to a rubbing ball mechanism and another driven shaft is attached to a finger pressing mechanism, with both mechanisms linked to a starter device through a connecting mechanism provided between the two mechanisms. A raising and lowering mechanism for the unit is connected with a tapping spindle which can rotate in a forward or reverse direction and is linked to a motor for raising and lowering the unit.

Abstract: A portable vibration finger pressure massager provides finger pressure massage to a body part of the user through the turning motion of massaging balls when the motor rotates in a first direction and simultaneously provides vibration and finger pressure massage when the motor rotates in an opposite direction. A weight change structure is attached to the rear shaft of the motor and becomes unbalanced when the motor rotates in the opposite direction, thereby causing the motor to vibrate. The vibration of the motor is transferred to projections provided on the massager thereby enabling the provision of vibration massage.

Abstract: A finger pressure device for massaging includes a box having a pair of framelike slidable holding trunks provided on opposite sides thereof, a starting motor fixed in the center of the box and having a hollow starting shaft with a female screw part inside, and a T-shape supporting bar having a rear part with a supporting male screw part which engages with the female screw part of the starting motor. The forward part of the T-shape supporting bar has a pair of opposed finger pressure disks on opposite sides thereof. A pair of slidable holding plates can slide inside the slidable holding trunks and their ends are connected to the outer ends of holding parts of the finger pressure disks. The T-shape supporting bar extends and retracts by rotation of the starting shaft in one direction or the reverse direction, and each finger pressure disk extends and retracts repeatedly.

Abstract: The body of a vibration transmission device is equipped in the seat and the back of a chair for office work to provide a vibration massage of wide range to the hip, thigh, and spine of the user. The vibration body has U-shape wire rods around a plate and is equipped in at least one of the seat and the seat back of the chair.

Abstract: This invention is easily assembled walking stick which disposes wheels at the lower end, and it enables user to walk forward in stable state without danger.This walking stick helps aged persons and sick persons and physically handicapped persons to walk.And it comprises the main walking stick with a wheel which has the hollow support bar disposed the forward wheel rotatably at the lower end and the assistant walking stick with a wheel which has the hollow assistant bar disposed the back wheel rotatably at the lower endThe main walking stick with a wheel and the assistant walking stick with a wheel are tied with the fastening bar member and the hook.The forward wheel is adjusted by the brake structure.The hollow support bar can be folded or contracted and expanded.And it helps user to walk in stable state.
