摘要:
Disclosed is a method of forming a ferrite film on particulate and/or fibrous substrate by adding an oxidizer solution and a ferrous ion solution to a deoxidized solution containing particulate and/or fibrous substrates to form a thin ferrite film on the particulate and/or fibrous substrates, wherein an addition amount of the ferrous ion solution is controlled such that an oxidation-reduction potential of the deoxidized solution keeps approximately a center point between the oxidation side and the reduction side, when a pH value of the dioxidized solution is adjusted to a constant value between pH 6 and 10.

Control units are mutually connected by separate common signal lines. A data link is provided between the control units via a preselected one of the common signal lines. A check is made as to whether the preselected common signal line is operating normally or abnormally. When the preselected common signal line is operating abnormally, the preselected common signal line is replaced by another common signal line in the data link.

An improved process for preparing a water-soluble polymer having an excellent water solubility and a high molecular weight, which comprises subjecting a thin layer of an aqueous solution of a water-soluble vinyl monomer to polymerization on a solid support, covering the thin layer with a substantially water-insoluble organic material, e.g. a paraffin, a silicone oil or a low molecular polyethylene, and/or a slightly water-soluble or substantially water-insoluble alkylene oxide adduct at least at a point of time when the aqueous monomer solution has not freely flowed, and further continuing the polymerization.

A travel locus display device has a display unit such as a CRT display to display a start point and a destination point of a vehicle and a travel locus of the vehicle from the start point to the destination point on a coordinate display area of a display screen of the display unit. The display screen is divided into four quadrants, one of which is selected as a display quadrant to which the destination point belongs. The display quadrant is displyed over an entire area of the coordinate display area.

摘要:
A DLC film mass-producing apparatus 10 includes a chamber 12 connected to ground. In the chamber 12, a plurality of plate-shaped substrates 60 are disposed in parallel at regular intervals, without disposing a counter electrode that faces each of the plate-shaped substrates 60. Sputtering cleaning is then conducted by plasma discharge and an underlying contact layer is formed on each of the plate-shaped substrates 60. Subsequently, a DLC film is produced on each of the plate-shaped substrates 60 by injecting a carbon source gas into the chamber 12 such that the internal pressure of the chamber 12 reaches 0.1 to 10 Pa and applying a negative DC pulse voltage having a pulse half width of 0.1 to 3 μsec to each of the plate-shaped substrates 60 to generate plasma.

There is provided a mold for extrusion forming of ceramic articles which is excellent in wear resistance and can remarkably decrease forming defects in the vicinity of outer peripheries thereof. The mold for the extrusion forming of the ceramic articles includes a die 1 having a plurality of back holes 9, and slits 8; a back pressing plate 12 and a back spacer 13 to adjust the amount of the kneaded clay to be supplied; and a pressing plate 11 and a spacer 10 to regulate the shape and size of the formed ceramic article. At least a portion of the supply end 22 of the die 1 which overlaps with the back pressing plate 12 is flattened, and a surface roughness (Ra) thereof is in a range of 0.05 μm to 10 μm.
摘要:
A silicon-based thin film mass-producing apparatus, including transparent electrodes placed to face in parallel to corresponding counter electrodes with a space therebetween, and silicon-based thin films are deposited on the transparent electrodes by feeding a raw material gas for depositing the silicon-based thin films into the chamber and by applying a DC pulse voltage to the counter electrodes to generate plasma. Unlike methods in which a radio frequency voltage is intermittently applied to perform discharge, a high plasma density distribution does not occur, and in-plane film thickness distribution does not occur. Furthermore, since the DC pulse voltage rises sharply, the ON period can be shortened. As a result, generation of a sheath ceases in the transient state before reaching the steady state, and the thickness of the sheath is small, which allows the space between the counter and transparent electrodes to decrease.
