The present invention provides: a spacer for a liquid crystal display, which is difficult to aggregate when dispersed onto a substrate in a dry manner; a production process for the spacer; and a liquid crystal display including the spacer. The spacer has a mean particle diameter of 0.5 to 25 µm, a coefficient of variation of 10 % or less in particle diameter, and a fluidity of 30 % or more, and preferably further has an electrification retention ratio of 40 % or more at 5 minutes after corona electrification.

Disclosed are a ceramics sheet which has an area of 400 cm² or more, thickness of 0.4 mm or less, maximum waviness height of 100 µm or less, and warp of 0.1 % or less and in which frequency of generated cracking and breakage is 10% or less when a load-applying test and a deflection-loading test each described in the text are carried out in succession, and a flat and large ceramics sheet having an area of 600 cm² or more and thickness of 1 mm or less. Further, disclosed is a method for producing a ceramics sheet having the characteristics described above and characterized in that in calcining a ceramics green sheet to produce a ceramics sheet, the green sheet described above is interposed between porous sheets which have bulk density corresponding to 30 to 85 % of the theoretical density and in which the shrinkage rate caused by heating up to the calcining temperature of the above green sheet is 5 % or less on condition that the periphery of the green sheet does not protrude from the porous sheets, and calcined.

A shell-and-tube heat exchanger for handling an easily polymerizable substance is disclosed, which is characterized by having no part for stagnation of said process fluid on the surfaces for contact with the process fluid. By eliminating undulations from the inner surfaces of the heat transfer tubes, it is made possible to prevent the easily polymerizable substance from polymerizing and, at the same time, prevent adhesion of a polymer to the surfaces. Thus, the efficiency of heat exchange is enhanced and the protracted continuous operation is realized.

A phthalocyanine compound is provided which exhibits particularly high transmittance to a visible ray, offers a highly efficient cut of a near infrared ray, excels in the ability to effect selective absorption in a near infrared region, excels in the solubility in a solvent, excels in the compatibility with a resin, and excels in heat resistance, light resistance, and weatherability, a method for the production thereof, a near infrared absorbable dye using the same, and a heat ray shielding material, a plasma display grade filter and a near infrared absorbable material formed thereof. The phthalocyanine compound of this invention is represented by the following formula (1): wherein Z 2 , Z 3 , Z 6 , Z 7 , Z 10 , Z 11 , Z 14 , and Z 15 independently stand for SR 1 , OR 2 , or a halogen atom, provided that at least one of them stands for SR 1 or OR 2 ; Z 1 , Z 4 , Z 5 , Z 8 , Z 9 , Z 12 , Z 13 , and Z 16 independently stand for NHR 3 , SR 1 , OR 2 , or a halogen atom, provided that at least one of them stands for NHR 3 and at least four of them stand for OR 2 ; a plurality of R 1 , R 2 , and R 3 , independently to each other, stand for a substituted or non-substituted phenyl group, a substituted or non-substituted aralkyl group, or a substituted or non-substituted alkyl group of 1 to 20 carbon atoms; and M stands for a nonmetal, a metal, a metal oxide, or a metal halide.

Synthetic resin structural members (11,11a) are inserted into a hollow joint member to abut each other in the joint member. A bearing-pressure damping member (15) is fitted into each bolt hole formed in the members. The axes of bolts (16) fitted in the holes extend alternately in mutually perpendicular directions. Due to damping action resulting from elastic deformation of the damping members, a load is substantially evenly disitributed over all the bolts to prevent concentration of the load on some of the bolts. The arrangement of the bolts with their axes extending alternately in mutually perpendicular two directions shortens the length of the joint member.
