A method of making molded parts employing Shape Deposition Manufacturing (SDM) techniques. First, SDM processes are used to make a layered structure having support segments and mold segments. The support segments are made of material which may be removed from the mold segments (e.g. dissolved or melted). The mold segments are made of a material which can function as a mold. The mold and support segments are sequentially deposited (e.g. in layers) and shaped (e.g. machined) to form a mold. The support segments define the shape of the part to be manufactured. The mold segments are removed from the support segments by dissolving or melting away the support segments, leaving an empty mold. Then, part material is cast into the empty mold. The mold is removed, providing a molded part. The part material can be a gelcasting slurry, for example. The present method provides homogeneous or heterogeneous parts having shapes which are accurately defined by the SDM process.

The present invention provides compounds for modulating protein kinase enzymatic activity for modulating cellular activities such as proliferation, differentiation, programmed cell death, migration and chemoinvasion. Compounds of the invention inhibit, regulate and/or modulate kinases, particularly Tie-2. Methods of using the compounds and pharmaceutical compositions thereof to treat kinase-dependent diseases and conditions are also an aspect of the invention.

The invention relates to an electrical multilayered component comprising a plurality of ceramic layers that are placed one on top of the other and arranged along a longitudinal axis, in addition to electrode layers arranged in-between said ceramic layers, wherein a ceramic rupture layer is arranged between two ceramic layers in at least one point of the longitudinal axis, said rupture layer having less stability with respect to tensile stress in longitudinal direction than the ceramic layers. The invention also relates to a layer stack from which the multilayered component can be produced. Uncontrolled emergence of cracks in the component is prevented by lower stability of the rupture layers.

A ring-like lubricant supply device 6 is fitted into a recess 4 of a nut member 2. The lubricant supply device 6 contains a lubricant and is formed in an outer peripheral surface with notches 7. Tubular members 8 each having an outer diameter larger than the diameter of the notch 7 are inserted into the notches, pushing and widening the notches 7 in a circumferential direction. One end of the tubular member 8 is fitted into a recess 9 b of a retaining ring 9 and the retaining ring 9 is fixed to a nut member 2.

A slide bearing fashioned as a ball bearing or a roller bearing, wherein contact portions of a roll shaft and a bearing, and rolling elements are formed of a combination of a ceramic material and a solid lubricant material. The slide bearing is advantageously utilized in a continuous hot dipping apparatus in which ball bearings or roller bearings are used as bearings of a sink roll and guide rolls of the apparatus.

Continuous hot dipping apparatus and slide bearing structure therefor

A continuous hot-dip plating apparatus has a roll assembly having superior resistance to erosion caused by the hot melt plating metal, as well as high resistance to wear of the shaft and bearings, which are immersed in the hot melt of the plating metal. A ceramic material is mounted on the sliding portions of the metallic roll shaft to make sliding contact with the metallic bearings and/or on the sliding surfaces of the metallic bearings which contact the metallic roll shaft. A clearance is left between the shafts and bearings to hold molten metal thereinbetween for lubrication.

In a casting method for manufacturing various types of ceramics products having an intricate configuration and a partly diversified wall thickness, such as compressor scroll blade and a screw rotor, by casting a slurry composed of ceramics, etc. in a mold (3, 7, 6), the improvement comprising an arrangement wherein the mold is partly or entirely formed of a flexible gel material (6) which can be melted by heating at a temperature lower than the boiling point of the dispersion medium, whereby the stresses generated when molding the product can be mitigated. Thus, the molding of a product having a high level of dimensional accuracy can be carried out with ease.

Slip casting method

PURPOSE:To enhance the corrosion resistance and wear resistance of a solid lubricating material and to prolong the life of the device by using ceramics and the inorg. solid lubricating material softer than the ceramics as a combination of the bearing surface to be slid and bearing sliding surface of a roll in contact with molten metal or rotating in the molten metal. CONSTITUTION:Either one of the sliding surface of the shaft of the roll or its bearing sliding surface is constituted of the ceramics hardly wettable with the molten metal and the other is constituted of the member contg. the inorg. solid lubricating material softer than the ceramics. As a result, the wear of the sliding surface is suppressed even if the molten metal or dross infiltrates the sliding surface. The plating device having a long life is thus obtd. The coefft. of friction of the sliding part of both mentioned above is small and the revolution of the roll is smooth and, therefore, the uniform hot dip metal coating is obtd.

Hot dip metal coating device

A mold with an increased compression strength and a good collapsibility is prepared with a good efficiency by mixing refractory particles with a binder material comprising a caustic alkali-neutralized product of a copolymer containing a carboxyl group and calcium hydroxide, thereby preparing molding materials, filling the molding materials around a pattern, and blowing CO 2 gas into the mold sand, thereby hardening the molding materials. Polyvinyl alcohol, calcium oxide, at least one hydroxide of zinc, aluminum, barium, magnesium, and iron, SBR latex, etc. can be added to the binder material, when desired.

Process for preparing mold

A slide structure comprises a roll shaft and a roll bearing. A whole circumference of the roll shaft is made of a sintered ceramics body. A sliding surface of the roll bearing is constructed by inserting a cermet into a carbon-carbon reinforcing graphite member. A continuous hot dipping apparatus has a roll supported and rotated in a molten metal bath. A sliding surface of the roll shaft and the roll bearing employs the slide structure. The corrosion resistivity and the wearing resistivity can be improved and a long service life can be attained. The slide structure comprised of the roll shaft and the roll bearing can be smoothly rotated by decreasing the friction coefficient of the slide structure.
