Title: Device for charging steel slab into heating furnace
Inventor: YAMAMOTO ISAMU
IPC: C21D1/00
Filed: 1988-11-30
Abstract: PURPOSE:To minimize opening area of a furnace at the time of charging a steel slab and to reduce heat loss in the furnace by arranging a lower door for closing/opening the lower opening part in the furnace while linking with ascent/descent of a charging beam at the time of charging the steel slab into the heating furnace. CONSTITUTION:When the charging beam 6 laying the steel slab 1 advances to the inlet of the furnace, at first, the upper door 9 is ascended and at the same time, the beam 6 is ascended to insert the beam 6 into a charging hole 8. Successively, the beam 6 is descended and after laying the steel slab 1 on skid, the beam 6 is retreated and returned back to the original position. Then, the lower door 16 is arranged at lower part furnace wall 3b, too and by driving an eccentric roller 20 while linking with ascent/descent and shift to front/rear of the beam 6, the lower door 16 is ascended/descended through a chain 22, sprocket 19 and chain 18 and the area of the opening hole 7 in the heating furnace at the time of charging the steel slab 1 is held to minimize, to prevent the lowering of the furnace temp. caused by invasion of cold outer air. By this method, the heat loss in the heating furnace is reduced and also, scale loss caused by rise of oxygen concn. in the furnace is improved.

Title: Contour line extracting system
Inventor: KOIZUMI JUNICHI
IPC: G06T1/00
Filed: 1988-11-29
Abstract: PURPOSE:To efficiently and highly accurately process the hierarchization of map data by extracting each contour line according to the feature of each contour line that each contour line is expressed with one line which is never crossed with other contour line and never disconnected. CONSTITUTION:The title system is equipped with a picture reading means 2 and a raster/vector converting means 4, and a contour line tracking means 6 tracks the connection relation between an arc and a contour line arc. Further, when a branchpoint, at which plural arcs and contour line arcs cross with each other, exists in the middle of the tracking, an intersection processing means 8 selects either the arc or the contour line arc having a gently bending direction at the branchpoint and detects a link group to be successively chained, when the arc or the contour line arc to be connected next does not exist in the middle of the tracking, an open endpoint processing means 10 generates new vector data and restores the chain in the contour line arc, and the data of the contour lines are prepared, in which each contour line can be expressed with one line. Thus, contour line information can be automatically identified, and hierarchization processing for the contour line data can be executed at a high speed with high accuracy.

Title: Folding spectacles
Inventor: KANDA KOJI
IPC: G02C5/08
Filed: 1994-12-06
Abstract: PURPOSE: To provide spectacles which are thinly foldable by forming ear bends of easily elastically deformable synthetic resins. CONSTITUTION: These foldable spectacles have auxiliary temples 31 pivotally fitted to the outer ends on the top side of a lens frame 1 and temple bodies 32 pivotally fitted to the free ends of these auxiliary temples 31. These auxiliary temples and temple bodies are foldable within approximately the same plane as the plane of the lens frame 1. The temple bodies 32 are composed of main parts 35 which are foldably connected to the auxiliary temples 31 and the ear bends 36 which are connected to the main parts 35 and have curving parts 37 for bow side ends. The ear bends 36 are formed of easily elastically deformable synthetic resins.  Since the ear bends 36 are formed of the easily elastically deformable synthetic resins, the ear bends 36 are pressed by a case cap 71 and are so elastically deformed as to be housed within the same plane as the plane of the lens frame 1 when the temples 3 are folded to the same plane as the plane of the lens frame 1 and the case cap 71 is closed at the time of housing the spectacles into the case and, therefore, the case 7 is formable thin without considering the curving parts 37 of the ear bends 36. Less bulky carrying of the spectacles is thus possible.
