Title: Improvement on surface properties of high boron-containing cubic boron nitride
Inventor: FURANSHISU REIMONDO KORIGAN
IPC: C23F1/00
Filed: 1982-02-08
Abstract: Boron rich cubic boron nitride suitable for use in electroplating processes (e.g. nickel plating) has been made by an acid leaching process. Boron rich aggregated cubic boron nitride grinding grits are leached in a mixture of nitric and sulfuric acids, the following conditions being typical; (a) volume ratio of 67% nitric acid to 98% sulfuric acid of 10:20; (b) temperature of 250 DEG  C; and (c) for a time of 1 hour. The process removes sufficient free surface boron to reduce the conductivity at the surface, resulting in an abrasive which does not overplate. FIG. 1 is a photomicrograph of a typical plated surface containing the improved CBN grinding grit of this invention, and FIG. 3 is an X-ray diffraction pattern characteristic of this new product.

The pixel electrodes 2-4 of MIM elements 2-5 are formed as transparent electrodes and counter electrodes 2-2 are formed as reflection electrodes. These reflection electrodes are formed by sputtering an Al-Mg (Mg is 3wt.%) alloy to 2000Angstrom  film thickness. The liquid crystal display element obtd. in such a manner is nearly transparent and allows the transmission of light when the voltage is not impressed thereto. The pixel parts are mirror-like. These parts are clouded when the voltage is impressed thereto. The entire part of the screen is clouded if the parts between the electrodes are colored in such a manner and, therefore, the extremely easily visible display is obtd.

Title: Ceramic heat transfer pipe
Inventor: YAMAGUCHI MINORU
IPC: F28F21/04
Filed: 1986-01-30
Abstract: PURPOSE:To provide a ceramic heat transfer pipe excellent in heat transfer performance with a small pressure loss of a fluid within the pipe, and easy in the fabrication, by causing ceramic particles to adhere to the inner surface of a heat transfer pipe made of ceramics. CONSTITUTION:A slurry-like glaze or frit or the like is applied beforehand onto required portions of the inner surface of a heat transfer pipe, and further ceramic particles are scattered in the pipe to be adhered on the ceramic particle applied portions, thereafter burning the particles. Since the inner surface area of the heat transfer pipe 1 is substantially increased by the ceramic particles 3 and the coarseness of the inner surface thereof is increased by the ceramic particles 3, an effect of stirring a material to be heated flowing through the inner part of the pipe 1 increases. Further, even when the flow of the fluid within the pipe is a low Reynolds flow, it is apt to become a turbulent flow, and hence a high heat transfer effect can be obtained. In addition, the ceramic heat transfer pipe according to the invention can be manufactured only by causing the ceramic particles to adhere to the pipe inside, its manufacturing cost is low and the pressure loss of the fluid within the pipe is small because the flowpath area within the pipe is hardly reduced.

Abstract: PROBLEM TO BE SOLVED: To simplify the switching operation of plural transmissions provided in a tractor, to restrain an unrequired car speed area so as not to be shifted and to improve operability. SOLUTION: The lower end of a sub speed change lever 21 and the upper end of a push arm 23 are connected by a rod 24, a sub arm 28 and a holder 29 are combined to the push arm 23 and the operation of the sub speed change lever 21 is transmitted to a shifter arm 25. When the sub speed change lever 21 is operated from a high speed position H to an overtop position HH, the pin 129 of the push arm 23 is moved forward inside the hole 131 of the holder 29. Simultaneously with it, a bar 30 connected to the pin 129 is pressurized forward and a stopper arm 27 is turned counterclockwise in the figure with a shaft 122 as a center. Thus, the rod 32 is pulled backward and a top arm 31 is turned to the high speed position. In such a manner, the switching operation of a sub transmission and an overtop transmission is made possible just by the sub speed change lever 21.  At the time of traveling on a road, by switching only a main transmission while keeping the overtop position, shifting to the unrequired car speed area is prevented and the operability is improved.

Title: Induction heating coil device
Inventor: HIROTA NARIYUKI
IPC: H05B6/40
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To simply compose a magnetic path having a shape running along an arbitrary curved surface on a surface of an induction heating coil opposite to its surface facing to a heated body. SOLUTION: The periphery of an induction beating coil 1 arranged on a surface of a heated body 2 is covered with flexible rubber 3 made by mixing magnetic powder of which surfaces each are coated with a non-conductive film. Since the magnetic powder is mixed in the rubber 3, the rubber 3 works as a magnetic path. The rubber 3 is flexible, so that it can be plastically deformed into a shape matching the periphery of the coil 1. Thereby, the magnetic path having a shape running along the periphery of the coil 1 is formed. By the formation of the magnetic path, a magnetic characteristic for induction heating is improved and the heated body 2 can be uniformly induction-heated.
