Title: Ion-implanted inorganic powder and method for implanting ion into inorganic powder
Inventor: KOKUBO TADASHI
IPC: C01B13/14
Filed: 1990-11-16
Abstract: PURPOSE:To improve the chemical stability of an inorg. powder by implanting at least nitride ion into the inorg. powder as the oxide of a typical or transition element. CONSTITUTION:Nitrogen gas is supplied to an ion generating part 2 in vacuum. The nitride ion generated is drawn out by a drawing electrode 3. The generated ion beam is formed by an electrode group 4 and introduced into a mass separator 5. Only the necessary nitride ion is separated, brought out, accelerated by an accelerating electrode group 6 and introduced into a chamber 7. The inorg. powder such as SiO2 shown by the general formula RnOm(R is a typical or transition element, and n and m are an integer of >=1) in the chamber is irradiated with the nitride ion beam. The nitride ion is implanted into the inorg. powder by the irradiation. Consequently, the chemical stability of the inorg. powder is improved without its R-O bond being split even by the presence of moisture, etc. Accordingly, even if an aq. soln. of the SiO2 implanted with the ion is prepared, the Si-O bond is not split by H2O, and the elution of Si is prevented.

Abstract: PROBLEM TO BE SOLVED: To increase a load capacity by reducing the stress generated in a rim in the bottom of a flexible external gear and in an inner ring rolling surface of a wave generator. SOLUTION: A position separated by an arbitrarily selected deflection angle θof 45 deg. or less from a major axis 3a of an elliptic rim neutral line of a flexible external gear, in an axial right angle section selected in an arbitrary place in a tooth trace direction of the flexible external gear, is set to a meshing center position of both gears, a basic shape of tooth form formed with a meshing main part of both the gears is respectively formed in a circular arc, and a relation between radii thereof is regulated by a theorem of Euler-savary materialized in a speed change ratio gear.

IPC: F02D41/00
Filed: 1986-12-26
Abstract: PURPOSE:To reliably decide a high temperature restarting time and to perform optimum control of damping of fuel, by a method wherein the damping speed of fuel, an amount of which is increased during starting, is varied according to the rising speed and the lowering speed of the number of revolutions of an engine. CONSTITUTION:Signals from a cooling water sensor 38 and a rotation angle sensor 48 are inputted to an engine control device 45, and an increase value f fuel from a fuel injection valve 26 is set according to the temperature of cooling during starting. When a fuel increase value is damped after starting, the rising speed and the lowering speed of the number of revolutions of an engine are detected. When a rising speed is high, a damping speed is increased, and when a lowering speed is high, the damping speed is decreased. This constitution reliably decides a high temperature restarting time at which vapor lock occurs, and enables accurate control of damping of fuel.
