IPC: C22B9/04
Filed: 1993-12-20
Abstract: PURPOSE:To automatically detect the casing of splashes and automate a remedy to avert danger by subjecting the lightness on the surface of the molten metal outside a reaction chamber for a molten metal treatment to an image analysis with a monitor camera at the time of immersing the lower part of this reaction chamber into the molten metal and blowing gas and/or adding an alloy thereto.

The lightness of this image is binarized by an image analyzer 10, by which the relative changes of the image area and the area of the part higher than the preset surface brightness of the surface are determined. These values are inputted to a control section 11, which emits a fault display alarm when the values attain the respective threshold values or above. Gas blowing is automatically stopped or the depth of the reaction chamber is increased when the large splashes are estimated to be caused.

IPC: B65H5/06
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce the impact sound by rattling of a gear in turning-on/off a drive source by providing a backup gear rotating independently from a driven gear and an energizing means energizing the backup gear in the rotational direction of the driven gear. SOLUTION: A backup gear 6 having a same tooth shape with an input gear 2a of a stage gear 2 is rotatably connected by a connecting means in such a state as being arranged coaxially with the stage gear 2 and independently from a moving stage gear. When a motor gear 1 is rotated in an arrow A direction, the stage gear 2 and the backup gear 6 is driven in an arrow B direction while keeping phase shift. On the other hand, when the motor gear 1 is stopped, the stage gear 2 receives a force continuously rotating in the arrow B direction from the effect of its inertia force, however, the force is absorbed by the backup gear 6 and a tensile spring 23a. As a result, the teeth faces of the motor gear 1 and the stage gear 2 are held in a contacted state at all times.

Filed: 1987-12-18
Abstract: PURPOSE:To allow a master to obtain more replicas by transferring a photoresist refraction grating pattern formed by a photographic exposure method by optionally changing only amplitude without changing the itch of a waveform. CONSTITUTION:The surface of substrate 2 is coated with photoresist 2 by a spinner. A sine wave-like resist refraction grating pattern is recorded on the resist 2 by a holographic exposure method. Then ion beam etching is applied to the surface of the resist 2 on which the pattern is recorded. The pattern formed on the resist 2 by etching is moved to the substrate 1 without changing the interval of a rugged pitch. At the time of moving the pattern on the resist 2 completely to the substrate 1, the ion beam etching is ended. Since amplitude can be optionally changed and transferred to the substrate 1 by changing etching gas or the materials of the substrate 1 and the photoresist 2.

Abstract: PURPOSE:To effectively utilize a main storage and to rapidly access the main storage by forming an array with the minimum size in the main memory at first, and when an array element not stored in the main memory is accessed and extension is required, allowing the main memory to secure a necessary side. CONSTITUTION:A page main storage allocating means 51 formed in a main storage control means 5 secures pages corresponding to the initial size necessary for an extensible array in the main storage 6.
