Abstract: A seal apparatus provides sufficient sealing and is compact and inexpensive. The seal apparatus includes a thread part screwed to the screw fastening part of a hollow component; a seal part that moves along an axis of the screw part and comes into pressure contact with the screw fastening part of the hollow component; a stopper part fixed to the screw part that restricts the movement of the seal part; a pressed part that moves the seal part into pressure contact with the screw fastening part; a spring disposed between the pressed part and the stopper part; and an accumulator formed between the stopper part and the seal part and into which a test fluid which is introduced into the hollow component for inspection flows.

Abstract: A gas-tight plug is attachable by pressing it against an opening portion of a hollow component, the gas-tight plug being inserted into the opening portion using the force of pressing to be automatically aligned so that if the positions of a plurality of opening portions vary within an allowable tolerance, the axial directions of all the opening portions and the axial directions of the respective gas-tight plugs are automatically caused to coincide. A gas-tight plug includes an end portion, a contact part of a base portion end of the gas-tight plug coming into contact with a base of the pressing mechanism has a circular flat surface coaxial with the end portion, and the circular flat surface has a diameter more than 0.12 times and less than 0.2 times a total length of the gas-tight plug.

Abstract: The purpose of the invention is to provide a transcranial magnetic stimulation system capable of being readily set into an optimum position for treatment. The system 1 of the invention includes a support mechanism 30 configured to support a patient, a first mechanism 200 configured to move the coil in a left and right direction of the patient about a first axis 220 extending in a back and forth direction of the patient relative to a head of patient supported by the support mechanism, and a second mechanism 300 configured to move the coil in the back and forth direction about a second axis 320 extending in the left and right direction relative to the head of the patient.

Abstract: The present invention relates to a nasal respiratory mask system comprising: a nasal mask that is tightly attached to the face of a user and serves as means for leading positive-pressure breathing gas to the nose of the user, a frame to keep the nasal mask at a predetermined position, and a headgear that is mounted on the head in order to attach the nasal mask tightly to the face; wherein, the headgear comprises, on the tip thereof, a headgear strap for adjusting the length of the headgear, the headgear strap comprises a headgear fastener that serves as means for connection/disconnection with the frame, the frame comprises a fastener catch that engages with the headgear fastener, and the fastener catch comprises an axisymmetric guide whose (rotation) axis is the insertion direction of the headgear fastener.

Abstract: A light weight nasal respiratory mask system securing airtightness of a mounting section between a nasal mask and a frame is provided.

Abstract: A headgear suitable for wearing a respiratory mask system wearing on the head of a user is provided, wherein it can be easily manufactured, the leakage of the positive pressure gas when pressurized is reduced, and a good wearing feel is achieved. The headgear is adapted to secure a respiratory mask, which contacts the face of the user to supply a positive pressure gas for respiration to the user, to the head of user. The headgear has a head mounted portion which is worn on the occipital of the user and a strap (3) connecting to this head mounted portion. The head mounted portion has at least one closed curved belt (1) which has thereon at least one junction (2). At least one junction provides the closed curved belt with a nonplanar structure adaptable to the shape of the head of the user.

Abstract: According to the present invention, there is provided a nasal respiratory mask contacting with the face of a user for supplying respiratory positive-pressure gas to the nose of the user, comprising at least a part attached tightly to the face that is attached tightly to the face of the user; a frame-fitting part for fitting to a frame; and an elastic connecting part that connects elastically the part attached tightly to the face with the frame-fitting part, wherein a facial side of the elastic connecting part is kept apart from the frame-fitting part side thereof for a required distance even in the absence of applied respiratory positive pressure. The nasal respiratory mask has advantages that it can be worn in an appropriate position without applying positive pressure at the start of wearing, scarcely disturbs the visual field during wearing, and can prevent prolongation of the time required for drying or occurrence of unsanitary condition after routine cleaning by washing with water.

Abstract: The invention provides a dialysate solution preparing apparatus for preparing a dialysate solution by mixing a powder dialysate medicament with water, in particular RO water. The dialysate solution preparing apparatus has a partition wall defining an accommodation chamber for accommodating a the container filled with the powder dialysate medicament. A container holder, provided in the accommodation chamber, holds the container at an inverted orientation where an opening of the container is disposed at the down side. A tank is provided under the holding means. After a cutter cuts the sealing member so that the powder dialysate medicament falls from the container, the water is applied to the powder dialysate medicament through a nozzle. The solution of the water and the powder dialysate medicament is supplied to the tank through a conduit.
