An inplane magnetic recording medium having high S/N and thermal stability and a reliable magnetic storage device having surface recording density of 50 megabit/mm2 or more is described. The magnetic recording medium includes magnetic layers formed on a nonmagnetic substrate with a plurality of ground layers therebetween, at least one of the ground layers formed from an alloy of a body-centered cubic structure containing Cr as a main component and B of from 2 atomic % to 12 atomic %. Main components of the magnetic layers include a lower magnetic layer containing Co and Cr of from 10 atomic % to 16 atomic %, with film thickness of from 1.5 nm to 4.5 nm, and an upper magnetic layer containing Co, coupling anti-ferromagnetically with the lower magnetic layer through nonmagnetic intermediate layers.

A glow plug includes a ceramic heater having a resistance-heating element embedded at its end portion. In order to supply electricity to the resistance-heating element, first and second heater terminals are exposed on the surface of the ceramic heater. First and second terminal rings, which serve as metallic fitting members, are shrink-fitted to the surface of the ceramic heater in such a manner as to cover and be electrically connected to the exposed first and second heater terminals. A metal layer not higher than Ni in ionization tendency is formed on the inner circumferential surface of each of the first and second terminal rings.

A brushless motor includes a motor housing, a stator, a positioning projection, and a groove. The stator is fitted in the motor housing and includes an outer core and teeth, which extend in the radial direction of the stator. A radially outward end of each tooth is coupled with the outer core. Each tooth has a predetermined width in the circumferential direction of the stator. The positioning projection is located on the inner circumferential surface of the motor housing. The groove is located on the outer circumferential surface of the outer core. The groove is arranged on a radial line that passes through the center of the width direction of one of the teeth. The positioning projection is fitted in the groove to determine the position of the stator with respect to the motor housing in the circumferential direction.

A silver halide emulsion having a silver chloride content of 90 mol % or more which has been chemically sensitized with a compound capable of releasing an AuICh− ion is described, wherein grains of the silver halide contain in the shell portion thereof 0.01 to 0.50 mol % of silver iodide per mol of the total silver, with Ch representing S, Se or Te.
摘要:
A device and a method for detecting isolated points in image data by the application of an isolated point detection filter, and discriminating whether or not the image data are a halftone dot image by the number of isolated point detected within a predetermined area. The size of the isolated points is reduced so as to be smaller than the isolated point detection filter by culling the image. In this way isolated points can be detected using the same isolated point detection filter regardless of the resolution of the image data.
