Title: Production of boron nitride
Inventor: FUKUMA YASUNOSHIN
IPC: C01B21/064
Filed: 1986-10-29
Abstract: PURPOSE:To obtain high-purity boron nitride efficiently, by previously reacting a boron compound with a nitrogen-containing compound in a molten state, grinding the reaction product and heating it in the presence of an inert gas or reducing gas at a given temperature. CONSTITUTION:A boron compound (e.g. boric acid, ammonium borate) is previously reacted with a nitrogen-containing compound (e.g. dicyandiamide, guanidine carbonate) in a molten state. The reaction temperature is properly 80-250 deg.C. Then the prepared reaction product is ground and heated in the presence of an inner gas (e.g. nitrogen) or reducing gas (e.g. hydrogen) at 800-1,600 deg.C to give the aimed boron nitride. Consequently, high-purity boron nitride free from sodium, calcium, potassium, magnesium, barium, etc., can be produced at relatively a low temperature by a simple process having no washing process which is required in the conventional method.

Title: Curing agent for epoxy resin
Inventor: INAGAKI HIROYUKI
IPC: C08G59/42
Filed: 1991-09-09
Abstract: PURPOSE:To obtain the subject agent which can give a cured epoxy resin of good heat resistance and high mechanical strengths by mixing two specified dicarboxylic acid anhydrides. CONSTITUTION:The objective epoxy resin curing agent is obtained by mixing 5-(2,4-dioxotetrahydro-3-furanylmethyl)norbornane-2,3-dicarboxylic anhydride (A) with methylnorbornene-2,3-dicarboxylic anhydride (B). When a conventional dibasic acid anhydride such as hexahydrophthalic anhydride is used, the heat resistance of a cured product is insufficient, and when an acid anhydride curing agent such as pyromellitic anhydride is used, the heat resistance of a cured product is excellent, but it is difficultly mixable with an epoxy resin because of its high melting point. When the component A is used alone, it is easily handled and can give a cured product of excellent heat resistance, but the cured product is defective in hardness and brittleness. By mixing the component A with the component B, the resulting mixture can give a cured product excellent in heat resistance and mechanical strengths.

Title: Speed change control method for continuously variable transmission for vehicle
Inventor: ISHIKAWA YOSHIKAZU
IPC: B60W10/10
Filed: 1987-10-12
Abstract: PURPOSE:To compensate lowering of engine output caused by decrease in atmospheric pressure by measuring the atmospheric pressure and increasing the target engine speed corresponding to decrease in the atmospheric pressure when the measured atmospheric pressure decreases. CONSTITUTION:A change gear ratio is controlled by a controller 100 as follows. First, the atmospheric pressure is input by an atmospheric pressure sensor, and a correction factor is input for the atmospheric pressure from a graph. The correction factor is 1.0 when the atmospheric pressure is standard atmospheric pressure (1 normal atmosphere), and the set factor is increased as the atmospheric pressure decreases. A target engine speed correspond ing to throttle opening is input and the target engine speed is multiplied by the above correction factor to be corrected. Secondly, speed change control is conducted to agree the actual engine speed with the corrected target engine speed. Accordingly, in case of running on highland where the atmospheric pressure is low, the target engine speed is corrected to be higher corresponding to the atmospheric pressure to compensate for lowering of an engine output.

Abstract: PURPOSE:To stabilize copying operation condition and to prevent careless copying operation from being performed by providing a pressure detecting element which presses a copying machine body and starting the copying operation only when pushing pressure higher than a specific value is applied to a surface to be exposed. CONSTITUTION:A light-transmissive buffer member 62 is provided over the nearly entire bottom surface of a platen plate 61 as the exposure surface of a copying machine which is placed on and pressed against an original to take a copy. When a top plate 10 is applied with pressure from above the copying machine, the force is transmitted to the platen plate 61 through side plates 11 and 12 and further to the platen plate 61 through side plates 11 and 12 and further transmitted to the surface to be exposed through the buffer member 62. When the pressure is increased, the buffer member 62 deforms conforming with the corner shape composed of the platen plate 61 and side plate 12 and a piezoelectric element 13 fixed to the corner part deforms to generate a voltage corresponding to the quantity of the deformation. When the pressure is increased enough to take a copy, the copying operation is started by the voltage generated by the piezoelectric element 13.
