Title: Production of optically anisotropic microsphere
Inventor: HATANO HITOMI
IPC: H01M4/587
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain optically anisotropic microspheres at low temperatures within a short time by feeding coal tar (pitch) into a heat treatment apparatus, heat-treating the feed while blowing a specified amount of an inert gas into the bottom of the reaction zone, and separating the product by extraction. SOLUTION: A feedstock comprising coal tar and/or coal tar pitch is fed into a heat treatment apparatus and heat-treated while an inert gas (e.g. nitrogen) is blown into the bottom of the reaction zone of the apparatus at a flow rate of 20-200Nl/min. Thus, the low-boiling component contained in the feedstocok can be sufficiently distilled out of the system to heighten the concentration of the βcomponent (a toluene-insoluble and quinoline-soluble component) which is the major controlling factor for the reaction of forming optically anisotropic microspheres. Therefore, optically anisotropic microspheres can be formed within a short time at temperatures lower than the convetional. The formed microspheres are separated by extraction. The microspheres are useful for high-density isotropic carbon materials, etc.

Abstract: PURPOSE:To obtain a highly reliable semiconductor structure wherein heat dissipation efficiency is excellent, the size is small and compact, and the cost reduction is enabled, by forming a channel to make cooling fluid flow in an element region where a semiconductor element is formed. CONSTITUTION:In the adjacent part of the main surface 1a of a semiconductor 1, a channel 2 to make cooling fluid, e.g., water, flow is formed in a spiral type. Pipes are connected with an outlet 3a and an inlet 3b of the cooling fluid, by using joint tubes corresponding with the hole-diameters of the outlet and the inlet. Through the pipes, the cooling fluid is made to flow. That is, since the channel 2 to make the cooling fluid flow is directly formed in the semiconductor substrate 1, a small-sized and compact heat dissipating structure is obtained. At the time of operation of the semiconductor element, the generated heat is effectively dissipated in the cooling fluid flowing in the channel 2, only via the semiconductor substrate material.
