According to an aspect of the present invention, a medical device is provided, which comprises the following: (a) a hollow elongate body (e.g., a elongate cylinder, such as a needle) having distal and proximal ends; and (b) a rotatable member comprising a tissue morselizer and an elongate shaft (e.g., an auger-like tissue-drilling bit). In the devices of the present invention, the elongate shaft is disposed within the hollow elongate body and cooperates with the hollow elongate body to (i) advance material (e.g., morselated tissue) toward the proximal end of the hollow elongate body when the shaft is rotated in a first direction, and (ii) advance material (e.g., a therapeutic agent and / or a bulking agent) toward the distal end of the hollow elongate body when the shaft is rotated in a second direction that is opposite the first direction. According to another aspect of the invention a method of treatment is provided that comprises: (a) inserting the a medical device like that above into the tissue of a patient; (b) morselizing and removing tissue from within the patient while rotating the shaft in a first direction, thereby creating a void within the patient; and (c) introducing a therapeutic agent and / or a bulking agent into the void.

A vehicular lamp includes a light source positioned inside a lamp chamber. The lamp chamber is formed from a lamp body fixed to a vehicle body and a front cover that covers a front open portion thereof. The vehicular lamp includes a light guide that includes a side end surface to which light emitted from the light source is incident on one side thereof; a light-emitting surface that emits the light that is incident from the side end surface in a predetermined direction; and a reflective back surface that has a reflecting portion that faces the light-emitting surface. The light guide made from translucent material that is positioned on one side inside the light chamber following along with the shape of the lamp front cover. A plurality of stippling steps that have a generally conical shape are provided on the reflective back surface of the light guide. A central axis that passes through an apex angle of every stippling step slants toward the predetermined emission direction of the light with respect to a virtual vertical line perpendicular to the reflective back surface.

A support for a screen assembly for a vibratory separator, a screen assembly with such a support, a vibratory separator with one or more such screen assemblies, and a method of using such a screen assembly, such a support having a body, a first series of holes through the body each hole having a first opening size as viewed from above, a second series of holes through the body each hole with a second opening size as viewed from above, the second series of holes at a selected area of the body and the support positionable in a vibratory separator so that the selected area is adjacent a selected location with respect to the vibratory separator, and the second opening size smaller than the first opening size and / or the second series of holes with holes spaced apart differently than the holes of the first series of holes; and in one aspect, a plastic grid with such hole series for fusing together layers of screening material.

An optical displacement sensor structure includes a plurality of light receiving elements and a plurality of optical fibers together with one light source, wherein light emitted from the one light source is efficiently introduced into the plurality of optical fibers from the circumferences of the optical fibers, well kept inside the optical fibers while transmitting therethrough, and exits out from the end face of one end portion of each optical fiber so as to impinge on each light receiving element. This structure, with only one light source, provides a plurality of optical displacement sensors thus reducing power consumption without suffering a problem of light loss and successfully enables downsizing.

A method and an apparatus for advantageously introducing a flame, a high velocity oxidizing gas, and a high velocity particulate flow into a furnace for metal melting, refining and processing, for example, steel making in an electric arc furnace. The steel making process of an electric arc furnace is made more efficient by shortening the time of the scrap melting phase, introducing a more effective high velocity oxidizing gas stream into the process sooner to decarburize the melted metal and introducing a more effective particulate injection to reduce FeO, form or foam slag and / or recarburize. Improved efficiency is obtained by mounting a fixed burner / lance and carbon injector lower and closer to the hot face of the furnace refractory at an effective injection angle. This mounting technique shortens the distance that the flame of the burner has to melt through scrap to clear a path to the molten metal, and shortens the distance the high velocity oxygen and high velocity particulates travel to the slag-metal interface. One method includes supplying a plurality of oxidizing reaction zones with the high velocity oxidizing gas to decarburize the melted metal and a plurality of particulate reaction zones with high velocity flows of particulate carbon for reducing FeO and / or forming foamy slag. The particulate reaction zones are located on the downstream side of the oxidizing gas reaction zones so as to minimize any effect of the reduction reaction on the decarburization reaction and to recover a part of the hot FeO produced in the oxidizing gas reaction zones.

A pick-up style work vehicle includes a rollover protection structure (ROPS), a seat section including a forward driver's seat and a rear seat, and a rear seat posture changing mechanism for changing the rear seat in its position between a first posture where the rear seat is in a non-use condition and a second posture where the rear seat is in a use condition. A fore / aft length of the rear seat in the first posture is shorter than the fore / aft length of the rear seat in the second posture. The work vehicle also includes a partitioning member for partitioning the seat section from a space behind the seat section with the partitioning member being supported by the ROPS. The partitioning member is movable with being supported by the ROPS between a rearwardly displaced position immediately behind the rear seat and a forwardly displaced position moved forward from the rearwardly displaced position.
