Abstract: An operation device (1) includes first bases (81A, 81B) and/or second bases (72A, 72B) that are elastically deformable in the direction of a pivot axis (X1) so that a shaft (120) can be inserted into a shaft hole (110). A first protrusion (121) is formed on a distal end portion of the shaft and projects radially outward from an outer sliding surface (120E). The first bases (81A, 81B) include a first escape section (111) recessed radially outward from an inner sliding surface (110E). The first escape section allows the first protrusion to pass through the first base when the shaft is being inserted into the shaft hole with an operation member (80) located in an initial position. A first slip-off preventing section (113) circumferentially adjacent to the first escape section prevents the shaft from coming out of the shaft hole when the operation member is pivoted from the initial position to an end position.

Abstract: A housing body (10) for deglutition of a shaped solid (5) for oral ingestion which is stored therein, comprising a generally tubular water-resistant envelope (1); an opening-side end part (A) at one end of the envelope, having an unsealable structure part (2), and capable of forming an opening part (22) by removing the unsealable structure part; a shielding-side end part (B) at the other end of the envelope, having a means for preventing the shaped solid for oral ingestion from release, the means allowing liquid to pass therethrough but not allowing the shaped solid for oral ingestion to pass therethrough; and a storage chamber (6) storing the shaped solid for oral ingestion between the opening-side end part and the shielding-side end part is disclosed.

Abstract: A pair of left and right guide rails and a pair of left and right supporting rails which support the supporting frame of a quilt or the like, are provided with a pivot on one side of the sewing machine to permit circular movement. These rails are parallel to each other. A moving member is provided along the guide rails, and this moving member is moved by a moving apparatus. An anchoring member is also provided to anchor the member to the supporting frame. Furthermore, an apparatus for moving up and down, which allows the guide rails and the supporting rails to move in a circular manner using the pivot as a fulcrum, is provided to anchor the anchoring members of the supporting frame or to release the anchoring.

Abstract: An apparatus for feeding a sewing machine with a textile fabric with opposite side hems. The sewing machine has a needle assembly and a bobbin assembly which are vertically aligned with each other to sew a textile fabric placed at a position between the needle and bobbin assemblies. The feeding apparatus is designed to set and withdraw the fabric into and from said position.

Abstract: A mattress includes a mattress body and an elongated support. The body includes a fabric case and a pad contained therein, and is formed so as to have predetermined breadth and length. The support has a soft structure and is disposed at a predetermined lengthwise location of the body so as to extend in a direction of the breadth of the body. The inventive mattress is capable of serving as a health aid which is so arranged as to prevent the lower back region of the human body from sinking in a curved manner and also to press against the lumbar vertebra, thereby improving the blood circulation and assuring a comfortable sleep.

Abstract: A sewing machine has a rotatable machine head and a bobbin drive unit which is rotated in synchronism with the machine head. The machine head and a needle reciprocally movably mounted on the machine head are independently driven through coaxially disposed inner and outer shafts. The reciprocal movement of the needle is detected by a detector mounted on the machine head. When only the machine head is required to be rotated, the shaft for driving the needle is also rotated so that the needle is held in its top dead point.
