A rotational handle device rotates a medical instrument for vascular treatment in a tubular form including a tube for insertion by guiding of a medical guide wire inside. The tube includes a helical coil of metal, a tubular tip of metal secured to an end of the helical coil, and a cutting head of a blade shape, formed on the tubular tip, for cutting a lesion upon being rotated. A first rotatable tube rotates with the tube, and has a wire lumen. An externally operable second rotatable tube is secured to the first rotatable tube in an axial direction. An over torque preventing mechanism is disposed between the first and second rotatable tubes, and causes the second rotatable tube to rotate free from the first rotatable tube upon application of torque higher than the predetermined level to the second rotatable tube.

A wire flow rack system including a longitudinal wire, a roller wire, a roller and an optional cap. The roller wire is joined with and transverse to the longitudinal wire and includes an unsupported free end that projects beyond the longitudinal wire. The roller defines an axial bore, and is positioned on the free end so that the it is free to rotate about the roller wire. A end element, for example, a cap, can be joined with the free end to prevent the roller from disengaging the free end. The cap can be friction fit with the free end and easily, manually replaceable relative to the free end, without the use of tools.

The high-efficiency multifunctional modular interior air purification device is compact in design structure, has no noise pollution, low energy consumption and an obvious purification effect, and is suitable for use in various interior places.

A recoiler has a retractable cable with an attachment pad on the distal end of the cable for attachment to an item of merchandise. The cable is stored on a spring biased spool located within a recoiler housing. The housing is freely rotatably mounted on a post extending upwardly from a base plate secured to the spool housing by a fastener and adapted to be secured to a support structure.

The present invention is a breathing mask that is fully adjustable so as to enable a comfortable and leak proof seal around a patient's face. The mask includes a frame, a cushion, a hose connector, a strap, connector, a strap, and a headgear. The present invention ensures both comfort and effectiveness by enabling a full adjustment of various components such as the angle of the strap relative to the face mask and the adjustment of the size of the headgear. Furthermore, the present invention also allows for the free rotation of certain elements in order to maintain a sufficient seal without increasing the pressure applied to the patient.

A recording apparatus includes a housing body, an opening/closing member, attached to the housing body via a pivot shaft so as to be capable of rotating freely, that covers the surface of the housing body on one side thereof, and an ink tank having an injection port for filling an ink holding chamber with ink used in recording. Here, the ink tank is disposed so that one end thereof is positioned within the housing body on the opposite side of the housing body as the side in which the pivot shaft is provided, and has a stepped shape including a step portion, the step portion being provided on a side of the ink tank that is further from the pivot shaft. The injection port is provided in the step portion, and when the opening/closing member is opened and the ink is to be filled.

Machine tool simplifying maintenance, reducing manufacturing costs, and enabling high precision machining. The machine tool is equipped with: a bed furnished with a rectangular base, right and left sidewalls provided standing either side of the base, and a rear sidewall provided standing along the back of the base; a table disposed in the space surrounded by the three sidewalls; a first saddle shaped in the form of a rectangular frame shape, provided free to shift back and forth supported on the tops of the left and right sidewalls; a second saddle penetrated by a perpendicular through-hole and arranged free to shift sideways inside the first saddle frame; and a spindle head arranged free to shift perpendicularly inside the through-hole in the second saddle; and a main spindle arranged over the table and supported by the spindle head free to rotate centered on its axis.

A massaging body-gym apparatus is composed of a rod, at least two rollers, two positioning sleeves, two sealing covers and an elastic rope. A positioning device is installed in the roller, composed of a pair of half positioning bases and a positioning bar. The positioning sleeve has a blocking disc bored with a restricting hole for inserted by the positioning bar. With the positioning bar inserted in or separated from the restricting hole of the positioning sleeve, the roller can be positioned immovably or released to rotate freely, so that, combined with different postures, various parts of a human body can be exercised or massaged. In addition, the present invention is small and light, handy for carrying.

A spooling tool for paying out a fiber optic cable prewound on a spool region of a drop box or on an associated spool, when installing a cable at a user's premises. In one embodiment, the tool includes a base plate and a stud projecting from one side of the plate. An elongate arbor has one end secured to the stud in such a manner as to support the arbor perpendicular to the base plate. The arbor is dimensioned to pass through an axial passage in the box so that the box pivots on the arbor when the cable is unwound by an installer. A cap mechanism at the opposite end of the arbor retains the drop box on the arbor, and applies enough drag on the box to inhibit it from free wheeling on the arbor.

An operation device is provided with an outer support section 1c which projects towards an outer face of a button 1, an inner support section 1e which projects towards an inner face of said button 1, a maintaining section 5b which is provided on a decorative front panel 5 and which maintains said outer support section in free rotation, a maintaining section 3a which is provided on a button depression member 3 and which maintains said inner support section 1e in free rotation and a flange 1b which is provided continuously on the outer edge of the aperture of the button 1. Thus it is possible to provide a smaller device than the conventional example while maintaining the rigidity of the outer support section 1c. A smaller button 1 and smooth see-saw operation can be realized as well as reductions in escaped light.

A versatile turbine suitable for both hydraulic and pneumatic applications. The turbine's blades are affixed to the inner surface of a cylindrical shell which is free to rotate about an outside supporting structure. Rotational energy is transferred from the outer surface of the rotating cylindrical shell, usually by means of a gear; however, there may be applications better suited for a pulley means of transfer. The vacant central axis of rotation can be closed, by incorporating taller blades to achieve a larger surface area, resulting in greater efficiency, or open, by means of shorter blades forming a hole with the distal edges of the blades, to allow for passing fish and or debris to safely exit. The preferred embodiment further includes a means for electricity generation, water purification, and hydrogen production.

An information processing unit and batteries which can be carried with ease even if the batteries have been attached. Includes a main body division for executing given information processing; a first battery division which is attached to the first surface on the rear side of the main body division and is standing out from a second surface adjoining the first surface of the main body division; and a second battery division which is held onto an edge portion on the side of the first battery division which the edge portion stands out from the second surface, such that it can rotate freely in a direction to approach the main body division and also in the reverse direction to depart from the main body division, and one surface of the second battery hits the second surface when rotated in the direction to approach the main body division. Therefore, at the time of carrying the main body division, the first and the second battery divisions can be caused to lie along the first and second surfaces of the main body division so that the first and the second battery divisions can be integrated with the main body division.
