IPC: G11B5/85
Filed: 1986-02-12
Abstract: PURPOSE:To improve the corrosion resistance of the titled magnetic recording medium and to reduce the friction coefficient by forming a specified hydrate on the surface side part of a ferromagnetic metallic thin film layer, and then moistening the thin film layer. CONSTITUTION:The ferromagnetic metallic thin film layer consisting essentially of Co is formed on a substrate, the hydrate of Ce2O3 or the hydrate of Co3O4 is formed at least on the surface side part of the thin film, and then the thin film layer is moistened. The moistening can be carried out by the following methods. Namely, the thin film layer is exposed to steam having >=65% relative humidity, water droplets are sprayed on the thin film layer, the thin film layer is immersed in water, or water is coated on the thin film layer. A lubricant layer can be formed, as required, on the moistened thin film layer. The corrosion resistance is improved by this method, and a recording medium whose friction coefficient is reduced by the lubricating effect of the adsorbed water is obtained.

Title: Controlling method for combustion of combustion device
Inventor: KONISHI YOSHINORI
IPC: F23N5/00
Filed: 1990-02-13
Abstract: PURPOSE:To prevent a burner from being frequently changed over by changing over the burner such that there are different changeover points in processes where the amounts of combustion are changed from high to low combustion and from low to high combustion from each other. CONSTITUTION:A control circuit part 19 performs amount-of-combustion control with actuation of a first solenoid 8, a second solenoid 11, and a solenoid pump 24. After the elapse of time t since the solenoid pump 24 is operated at a flow rate P7 a room temperature thermistor 23 inputs room temperature to a calculation part. In succession, set temperature is inputted into the calculation part by switches 20, 21. In this state, the calculation part calculates the amount of combustion and provided the amount of combustion of Q8 or more is required, it actuates the second solenoid 11. Accordingly, since the second solenoid 11 has first been started from an operation state it keeps that state. Further, provided the amount of combustion falls within Q5-Q8 a present state is maintained. Furthermore, provided the amount of combustion may be Q5 or less, the second solenoid 11 is interrupted in its operation.

Title: Production of bent optical fiber, light-amplifier and optical part
Inventor: SAKANO SHINJI
IPC: C03B37/027
Filed: 1994-02-28
Abstract: PURPOSE:To obtain an optical fiber free from internal stress and capable of keeping sufficient reliability even at a small bend radius. CONSTITUTION:An optical fiber 5 formed by drawing a preform 1 is heated at the part to be subjected to bending work to the softening temperature in a heating furnace 7.

Title: Cryogenic freezer
Inventor: TANETANI SHOICHI
IPC: F25B9/00
Filed: 1990-02-08
Abstract: PURPOSE:To enable a re-cooling down operation to be carried out without performing any vacuum drawing and to simplify an operation when the operation is stopped by a method wherein some active carbons are fixed to an outer surface of a cryogenic temperature part facing in a vacuum container or a part of an outer surface of a connected equipment. CONSTITUTION:Some active carbons 9 are fixed to an outer surface of each of cryogenic temperature parts 1 to 7 adjacent to an interior part or a part of an outer surface of the connected equipment such as a pipe to be connected to a cryogenic part. More practically, some active carbons 9 are adhered to an end surface of the second heat stage 2 with adhesive agent. With such an arrangement, even if gaseous molecules are present in a vacuum container 8, a cooling-down operation causes the gaseous molecules in the container 8 to be adsorbed as the temperature decreases, resulting in that a vacuum pressure in the container 8 is decreased in sequence. Due to this fact, in the event that the operation is stopped after a long period of time and the operation is re- energized, the cooling-down can be carried out even if the vacuum drawing in the container 8 is not carried out for every time.

Abstract: PURPOSE:To detect an indexing miss automatically as well as to prevent a workpiece from being unmachined, by rotating a dividing plate further clockwise as much as one division after calculation of the specified indexing frequency of an index commanding device and, after judging operating frequency of a zero switch, reversing and resetting it to the zero position. CONSTITUTION:First a dividing plate 5 is reset to a zero position, and a zero switch 24 is turned off at the side of right clockwise rotation with a zero dog 5a. Next, when index numbers N equivalent to the number of teeth of a workpiece 6 is inputted into a setting means 20 and set to an index frequency calculating means 22, an index commanding means 21 rotates the dividing plate 5 and the work 6 clockwise as much as one division, thus machining is carried out by a cutter 8. At this time, the zero switch performs its on-off operation for the first time, setting N-1 with the index frequency calculating means 22 and indexing this N-1 till it becomes N=0, thus machining is repeated. And, when it becomes N=0, the dividing plate is further rotated clockwise as much as one division portion, and a fact that whether the zero switch 24 is turned on or off two time or not is judged by a judging means 27, and when it is less than two times, abnormality is displayed by a trouble displaying means 29, but if it is more than two times, the dividing plate is reset to the zero position. Thus, an unmachined work is detectable.
