摘要:
The present invention provides an improved multi-mold apparatus for manufacturing friction members, with each mold composed of a set comprising a first (top) mold, a second (bottom) mold, and a frame mold. The apparatus is capable of correcting any misalignment in the mountings of the plurality of molds and accurately aligning the molds by movably supporting at least one of the first mold, the second mold and the third mold by first, second and frame bases, respectively, so that the base and molds are movable laterally, in a direction perpendicular to the direction of advance. Projections are formed on one of the first mold and either the frame mold or the back plate and bonding through-holes are formed on the remaining mold or the back plate, so that the projections engage the holes so as to align the first mold and the frame mold accurately.

A manufacturing method for a monolithic ceramic part permitting a ceramic laminate to be cut stably and speedily, even if the thickness of the ceramic laminate is large. In order to divide a mother ceramic laminate into individual laminates of monolithic ceramic part units, the ceramic laminate is cut with a cutting blade, using a pair of guides disposed on opposite sides of the cutting blade in the vicinity of one principal plane of the ceramic laminate to control the cutting direction, and then individual ceramic laminates thus obtained by cutting are fired.

In order to eliminate erroneous reading of data by preventing noise which might otherwise be transmitted at the data reading time through parasitic capacitance in the data lines to other data lines, switches (Qt1 and Qt1′) are interposed between a sense amplifier (SA) for amplifying the potential of a data line (DL) and the data line, and the sense amplifier is fed with an operating voltage after the potential of the data line is transmitted to the sense amplifier, and the switch is turned off.

Proposed is a liquid coating composition for the formation of a siliceous coating film having good storage stability against gelation for the protection, levelling or electric insulation of various substrate surfaces. The composition is a uniform solution comprising:(A) a partial cohydrolysis-cocondensation product of(a) a first hydrolyzable silane compound represented by the general formulaHSi(OR).sub.3, in which each R is, independently from the others, an alkyl group having 1 to 4 carbon atoms or a phenyl group, and(b) a second hydrolyzable silane compound represented by the general formulaSi(OR).sub.4, in which each R has the same meaning as defined above, in a molar ratio of (a):(b) in the range from 1:9 to 9:1; and (B) an organic solvent to dissolve the component (A). The storage stability of the coating composition can be improved by removing the alcohol contained therein as the hydrolysis product of the silane compounds to such a content as not to exceed 15% by weight.
摘要:
A hydrophilic coating is formed on an aluminum surface by the application of an aqueous solution of an amphoteric acrylamide polymer which is dried in place. The polymer solution may contain a cross-linking agent and the dried coating may be subsequently treated to form a water-glass coating.
