Title: Treatment of magnetic powder
Inventor: KISHIMOTO MIKIO
IPC: C01G49/00
Filed: 1983-02-16
Abstract: PURPOSE:To obtain Co-containing iron oxide magnetic powder having excellent mangentic characteristics, age stability and thermal stability, by covering the surface of an acicular iron oxide magnetic particle with a layer of a bivalent iron oxide and with a Co-containing iron oxide layer, and heating the laminated powder under specific condition. CONSTITUTION:An iron oxide layer is applied to the surface of an acicular iron oxide magnetic particles such as gamma-Fe2O3 by using ferrous sulfate etc. containing bivalent iron ion. The coated surface is further coated with a Co-containing iron oxide layer using cobalt sulfate and ferrous sulfate. The laminated iron oxide particle is heat-treated at 200-400 deg.C in an inert gas atmosphere or in vacuum. A high-quality iron oxide layer uniformly containing bivalent iron ion and cobalt is formed by the treatment. The cobalt ion is oriented along the surface magnetic field of the acicular iron oxide magnetic particle, and magnetic particles having large uniaxial anisotropy along the direction of long axis and having improved coercivity can be obtained by this process.

Title: Fuel injection device in internal-combustion engine
Inventor: MANAKA TOSHIO
IPC: F02D41/30
Filed: 1982-02-19
Abstract: PURPOSE:To make it possible to supply a stable mixture over a whole operating range, by reducing the fuel pressure applied to an injector upon operation under low engine load so that the range at which the pulse width of fuel injection by the injector is short is not used. CONSTITUTION:Fuel pressure applied to the inlet of an injector 3 to which fuel sucked up by a fuel pump 8 is fed, is adjusted by a pressure regulator 9 for maintaining the pressure difference with respect to the injection port of the injector 3. A plunger 11 is disposed in the regulator 9 so that a set force due to a solenoid 10 and a spring 12 is altered for switching a set pressure difference by two steps. The plunger 11 is moved away from the solenoid 10 for returning the spring 12 when the solenoid 10 is deenergized, and therefore, the set pressure difference is made low. Thus the set differential pressure is lowered in the range where the injection width of an output delivered to the injector 3 becomes less than a predetermined value, thereby the pulse width is made long.

IPC: E02B3/06
Filed: 1993-01-19
Abstract: PURPOSE:To obtain a wave dissipating structure for a breakwater proper to be installed near a river-mouth.
