Abstract: A probe includes an insertion portion insertable into a body organ, a projecting portion being exposed to an outside of a body after the insertion portion is inserted into the body organ, a device mounting area onto which an external-device coupler is removably mountable, and sensing electrodes provided on the insertion portion and the device mounting area. When the insertion portion is inserted into the body organ, the sensing electrodes detect a biosignal and become conductive with coupling electrodes of the external-device coupler mounted onto the device mounting area. The probe is an electromyograph probe that detects a biosignal measurable by an electromyograph. The insertion portion and the projecting portion of the probe may be integrated or separate from each other. Both of the insertion portion and the projecting portion or only the insertion portion may be disposable.

Abstract: A connection device for detachably and strongly fixing two connection target members has two confronting lever members configured to swing about a fulcrum member, a screw hole formed in the lever member of the confronting lever members and an insertion hole, through which a screw passes, formed in the other lever member. Both the lever members are caused to approach each other by screwing the screw into the screw hole so that locking portions of the lever members are displaced so as to be moved upward through the fulcrum member constituting a fulcrum portion. A fixing device main body is fixed to one of connection target members by a screw passing through the fulcrum member and the locking portions are locked to the other connection target member.

Abstract: A frame, including a plurality of frame elements 1 and at least one connecting corner element 5 on which the frame elements 1 are mounted in intersected relation, is provided to form a readily accessed enclosure to accommodate therein an article, a glass plate to allow viewing of the article, a backing plate at the rear and an illumination louver. At least one of the frame elements 1 is mounted to the connecting corner element 5 for relative angular movement therebetween, to facilitate easy opening of the enclosure and access to the space defined therein.

Abstract: A picture frame device which allows the framing straight members to be removed from the front of the frame device by pivotally rotating the corner joints and has a space formed in a container installed behind the exhibit or the exhibit held between holding sheets, for containing many other exhibitable sheets than the exhibit such as pictures and testimonials.

Abstract: The present invention presents hinge structures for pivotably and detachably coupling two members, i.e., an axial member and an axial member support, in which a pivotal portion is provided at the base edge of an axial blade of the axial member; a disengaging protrusion is provided at the tip edge of the axial blade; a pivotal rotation guide is extended from near the disengaging protrusion; an engaging extension is provided at the tip edge of the pivotal rotation guide; an opening is formed in the axial member support; a pivotal portion rest is formed on one side face of the opening, while an engagement rest is formed on the other side face opposite to said one side face; a curvature is formed from the engagement rest to said one side face with the pivotal portion rest formed; a lock member is pivotably or slidably provided in the axial member, with its locking claw to be engaged with the engagement rest; and said hinge structure can be pivotably and detachably provided with various auxiliary devices.

Abstract: An intrauterine device constructed of a flexible plastic and comprising a stem having adjacent one end a plurality of arms or branches extending laterally therefrom and being biased slightly in a direction toward the opposite end; the planes of said arms being at an angle of less than 90.degree. to the plane of the stem and said arms being flexible about their juncture of engagement to said stem for bending toward or opposite the remote end thereof. Said stem remote from said arms is relatively thin and elongated and with there being a hook in its said remote end extremity. A tool for inserting said device is provided having a chamber for accepting the thin elongated portion of said device and finger-like guides embracingly engaging opposite sides of said stem between arms thereof and having its device engaging portion formed on a radius for promoting facile disengagement from the device upon limited longitudinal tilting of the tool when the device is in operative position.
