When mated the male and female fittings may engage along their respective interfacing upper bases and lower ends of their respective lateral side faces.


Method for manufacturing a silicon cylinder by growth on seeds in a directed solidification furnace

A method for manufacturing a silicon cylinder by growth on seeds in a directed solidification furnace, including at least the following steps: (i) providing a crucible having a longitudinal axis (z), in which the bottom is covered with a layer of seeds of monocrystalline silicon in a right prism shape; and (ii) proceeding with directed solidification of silicon by growth on seeds, in a direction of growth that is co-linear with the axis (z) and with a concave solidification front, spatially or temporally; characterised in that the layer in step (i) of: one or more central seeds gc; and one or more peripheral seeds gp contiguous to the seed(s) gc, the peripheral seeds gp having a specific size.. .


Solid-core ring-magnet

A solid-core ring-magnet having one or more cavities is provided. The magnet can have an overall cylindrical shape or a rectangular-prism shape.


Apparatus for manufacturing composite leaf spring

An apparatus for manufacturing a composite leaf spring, including: a supply roller configured to wind a reinforcing fiber on an outer circumference thereof; a resin impregnation unit configured to supply a synthetic resin to the reinforcing fiber withdrawn from the supply roller; a polyprism-shaped rotating mold unit rotatably disposed at one side of the resin impregnation unit, and having molding grooves formed along an outer surface in a circumferential direction thereof to be in communication with each other and disposed in multiple rows; and a supply arm including a withdrawing means configured to protrude to one side of the resin impregnation unit and to withdraw the reinforcing fiber, and an elastic guide configured to guide the reinforcing fiber to each of the molding grooves.. .


Blade insert illuminator

A blade insert illumination system includes one or more illumination elements composed of a transparent or semitransparent polymer that is preferably biocompatible and sterilizable. The illumination elements operate as a waveguide and may incorporate optical components such as, for example, facets, lenses, gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy.
