摘要： A coating type, magnetic disk is produced by applying a magnetic paint containing magnetic powders in a dispersed state to a non-magnetic substrate, thereby forming a magnetic recording film thereon, and applying surface waves to the magnetic recording film in an undried state. By applying the surface waves to the magnetic recording film, dispersibility and orientation of the magnetic powders are improved and a longitudinally oriented, coating type magnetic disk with distinguished electromagnetic properties, such as a high S/N ratio, etc. can be obtained.

摘要： The present invention proposes a ratio of an applied field H.sub.s to a coercivity H.sub.c as a parameter which gives an influence to the write/read characteristics of a magnetic coated recording medium, especially, a reproduction output E.sub.o at a low recording density and a recording density D.sub.50 which provides an output of the half of E.sub.o. By selecting the ratio H.sub.s /H.sub.c to be not larger than 2.1, a magnetic coated recording medium having large values of E.sub.o and D.sub.50 or suited to a high density magnetic recording can be provided with good reproducibility.

摘要： Gas contaminants generated from the grease of bearings operating in a magnetic disk device adhere to the magnetic head and causing stiction and magnetic head crash. Such bearings are typically spindle bearings and pivot bearings. In operation, heat is generated that causes the bearing grease to generate the gases. By heat treating the grease, slow evaporating substances of hydrocarbon compounds with carbons of C9 to C13 in the grease are reduced to not more than 0.001 wt. % of the grease. The grease can then be used to lubricate the bearings. The heat treatment is performed at a temperature of 60.degree. to 100.degree. C. at a pressure of 10.sup.-3 to 10.sup.-8 torr. The assembled, lubricated bearings can be heat treated separately from the magnetic disk device or the heat treatment can take place after the bearings have been assembled in the magnetic disk device.

摘要： A method for producing optical glass, which comprises charging a mixed solution capable of forming a high-silica-content gel by hydrolysis reaction into a vessel, the inner wall face of which is composed of a material unwettable to the mixed solution, such as a fluorocarbon resin or silicone resin, causing gelation of the mixed solution in the vessel, drying the obtained gel, and heating and sintering the obtained dry gel. When electrodes are placed in the mixed solution at the gelation step and an electric voltage is applied, the time required for formation of the gel is shortened. Furthermore, at the gel-drying step, if the amount of materials evaporated from the gel is detected or the weight of the gel is measured, the detected amount of the evaporated materials or the change of the weight of the gel is fed back to a factor regulating the drying speed, such as the drying temperature to control the drying speed to an appropriate level.
摘要翻译：一种光学玻璃的制造方法，其特征在于，将能够通过水解反应形成高二氧化硅含量凝胶的混合溶液装入容器内，该容器的内壁面由不能混合的溶液的材料构成，氟树脂或有机硅树脂，使混合溶液凝胶化，容器干燥，加热烧结得到的干凝胶。当在凝胶化步骤中将电极置于混合溶液中并施加电压时，形成凝胶所需的时间缩短。此外，在凝胶干燥步骤中，如果检测到从凝胶蒸发的材料的量或测量凝胶的重量，则将检测到的蒸发材料量或凝胶重量的改变反馈至调节干燥速度的因素，如干燥温度，将干燥速度控制在适当的水平。

摘要： A method for producing an optical fiber preform comprising the steps of blowing, through at least one nozzle, gaseous material producing glass material soot by a CVD reaction to permit the glass material soot to be deposited on a target to produce a soot rod which grows in size, and heating and rendering transparent the soot rod produced in the first step, wherein a pipe is arranged substantially concentrically with the glass material soot so as to permit gas to flow through a clearance between the deposited glass material soot and the inner wall surface of the pipe in a direction in which the soot rod grows in size. The method makes it possible to prevent the outer peripheral portion of the soot rod from becoming porous and to satisfactorily control the diameter of the soot rod.
