A blade is repaired by utilizing a super abrasive machining quill and / or wheel to form the contour and restore the height of the blade. By utilizing super abrasive machining, the contour and height can be quickly returned to desired dimensions by removing unwanted added material.

The invention relates to a milling tool for machining non-metallic materials, in particular wood, wood-based materials and plastics, which has a carrier (3) into which a corresponding number of tools can be inserted in the radial direction on the circumferential side A plurality of cutting elements (1) in an extended recess (2), which can be screwed to the carrier (3) via holes (15), said cutting elements being plate-shaped and in cross-section Basically triangular in shape and provided with a cutting edge (11) on one side edge, it is characterized in that the cutting element (1) has the following features: a) the area (12) opposite the cutting edge (11) is inverted circle, b) a groove (14) is provided in the underside (13) extending substantially at right angles to the cutting edge (11), c) the hole (15) divides the groove (14) preferably into two regions , is also characterized by the following feature of the hollow slot (2): d) extends upwards in the radial direction from the bottom (21) of the hollow slot serving as a support surface for the cutting element (1) tab (22), which is associated with the groove (14), e) a radial threaded hole (23), which preferably divides the tab (22) into two regions , and f) the cutting element (1) is only characterized by its underside (13), the side wall (17 or 18) of the groove (14) and the A part of the area (12) is in contact with said cavity (2).

A navigation guide wire (1 ) through an anatomical apparatus, for example a vascular system, unusually capable of being safely positioned proximate to bifurcations, comprises: - an elongated body (19) having a proximal end (21 ), a distal end (20), and a longitudinal extension along an axis (x-x) extending at least from said proximal end to said distal end; - at least one first proximal portion (4) having a predetermined first flexural rigidity (KfI ) capable of a first predetermined flexure in at least one plane comprising at least one portion of said longitudinal axis in order to allow a first curvature to said proximal portion when bending stressed, while ensuring a predetermined elastic return in a rectilinear position of the elongated body proximal portion when not subjected to stresses; - at least one second distal portion (3) having a predetermined second flexural rigidity (Kf2), the amount of which is equal to or higher than said first flexural rigidity of said at least one first proximal portion, capable of a predetermined flexibility of said second distal portion in order to obtain a second curvature when bending stressed in at least one plane comprising at least one portion of said longitudinal axis, while ensuring an elastic return to a rectilinear position of said distal portion of said elongated body when not subjected to stress; - at least one intermediate length (6), arranged between said first proximal portion and said second distal portion, having a third flexural rigidity (Kf3) essentially lower than said first flexural rigidity (KfI ) and said second flexural rigidity (Kf2), which allows a predetermined flexibility capable of a third curvature substantially more pronounced compared to said first curvature and second curvature, so as to allow a considerable direction change between said first proximal portion (4) and said second distal portion (3).

One embodiment of the present invention provides an ultrasonic probe for otolaryngology, comprising: a handle part enabled to be grasped by the hand of a user; a lens part inserted into the oral cavity to make contact with the skin therein and having a fixed curvature radius; a head part including the lens part on one side thereof and having rounded edges; and a connection part for connecting the head part and the handle part and forming a first angle with the head part.

A square lithium secondary battery includes a wound body in which a collective sheet in which a positive electrode sheet and a negative electrode sheet overlap each other with a first separator interposed therebetween is wound while a second separator is put inside the collective sheet. An active material mixture layer on one or both surfaces of at least one of the positive electrode sheet and the negative electrode sheet includes a region with a plurality of openings and a region with no opening. At least a bent portion of the collective sheet is covered with the region with the plurality of openings.
