A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (A.sub.C). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.

Method for producing ceramic components, more particularly ceramic components having recesses and/or hollow spaces, there being at least one sintered ceramic part present. In order to improve the handling qualities of ceramic components, the sintered ceramic part can include a carrier or carrying section which is removed in the further processing from at least one ceramic component.

The present disclosure discloses an interlocking roof tile comprising two groove extending over length of the interlocking roof tile at both lateral ends that create side walls at the distalmost ends of the interlocking roof tile. The grooves are created on top surface of the interlocking roof tile using a press machine that uses pressure to mold the cement into the interlocking roof tiles. The interlocking roof tile's at bottom surface is flat. The interlocking roof tile further comprises at least one nail opening, provided spatially from each other to mount and secure the interlocking roof tile to the roof. In order to couple a plurality of interlocking roof tiles in series, a first interlocking roof tile is placed coupled to the second roof tile such that side wall of the first interlocking roof tile is engaged with the groove of the second interlocking roof tile.

The present invention relates to a ceramic ball having a detergent function and a method for manufacturing a ceramic ball, which can improve washing capacity since the ceramic ball is molded such that the surface area coming into contact with water gets wider, and can improve production efficiency and reduce the manufacturing cost since it is possible to manufacture ceramic balls continuously and automatically.

A sensor element (12) has a cross-sectional area that continuously only increases from a positive (+) electrode side toward a negative () electrode side, thereby leading a hot spot, which attempts to move to the negative electrode side, to a lower resistance side. A position that is at nearly equal distances from paired electrodes (13 and 15) formed on either end of the sensor element (12) is set as a hot spot generating position, so as to avoid damage to the electrodes due to heat emitted by the hot spot.
