Title: Metal cobalt magnetic powder and preparation thereof
Inventor: SUEYOSHI TOSHINOBU
IPC: C22C19/07
Filed: 1983-03-18
Abstract: PURPOSE:To prepare a metal cobalt magnetic powder having good magnetic characteristics and suitable as a magnetic recording medium suitable for high density recording, by coating the surface of a plate shaped cobalt hydroxide powder with a sintering preventing agent while reducing the coated powder under heating in a reductive atmosphere. CONSTITUTION:A plate shaped cobalt hydroxide powder is added and dispersed in an aqueous alkali solution in which a known sintering preventing agent is dissolved and, thereafter, CO2 gas is blown into said solution or an acid is added thereto to neutralize said solution. Whereby, the surface of the cobalt hydroxide powder is coated with a crystalline or amorphous sintering preventing coating. Because the shape of the plate shaped cobalt hydroxide powder particle is effectively held and the sintering between the particles is effectively suppressed, heating reduction is performed sufficiently well and reducing reaction is also uniformized. As a result, the plate shaped metal cobalt magnetic powder having high coercive force and high magnetic saturation susceptibility is obtained.

Filed: 1988-02-29
Abstract: PURPOSE:To save power consumption by stopping a total time operation in which a control frame is sent in case of finding no information addressed to one's own by detecting the information addressed to one's own in a terminal. CONSTITUTION:A radio terminal part set at a waiting state starts up a data reproducing part 2 by controlling a parity control part 4 via a radio terminal control part 3, and receives a frame control signal from a radio base station setting a terminal part 5 at a reception state when the transmission cycle of the base station is set by a radio reception part 1. And the control part 3 detects the information addressed to its own station, and when the number of terminals to which the base station transmits the information is less than that of channels in the control frame, the part 3 discriminates a control frame signal to which no information signal is inserted to the remaining channel of the control frame, and stops power supply during that frame period of no information signal to the reproducing part 2 and the radio reception part 1 via the control part 4. As a result, power consumption can be reduced.

Abstract: PURPOSE:To obtain a given wiring width by a method wherein on a metal layer on a semiconductor substrate, a film of the oxide of said metal is formed and selectively etched to form a mask, which is used to etch the metal layer therebelow. CONSTITUTION:In an Si substrate 1, a base 2 and an emitter 3 are provided, and electrode windows are opened in SiO2 4. Then, Al 5 is deposited thereon by evaporation and anodized to form an alumina layer 6. A resist mask 7 is applied, and the alumina 6 is selectively etched by using a solution of fluoric acid, sulfuric acid and water in the ratio of 1:10:100. Then, with the alumina 6 as a mask, the Al 5 is etched by using a mixture of phosphoric, acetic and nitric acids. Finally, a resist mask is applied, and the alumina 6 is removed by etching. By said constitution, because a mask of the alumina 6 of excellent adhesive properties is used for selective etching of the Al 5, lateral spreading is prevented in etching. Moreover, because the alumina and the Al are not removed simultaneously, there is no lateral spreading due to nonuniformity of the film thickness of the alumina 6 or the etching amount. Accordingly, a desired wiring width can be obtained.
