Title: Manufacture of semiconductor device
Inventor: TAJI SHINICHI
IPC: H01L21/3065
Filed: 1986-12-25
Abstract: PURPOSE:To shorten the etching treating time by regulating the temperature of a substrate so that the predetermined etching ratio of a plurality of workpieces on the surface of the substrate is obtained and etching the workpieces. CONSTITUTION:The etching ratio of a plurality of workpieces (including semiconductor substrate 1 itself and a coating film formed onto the substrate 1) on the surface of the substrate 1 is adjusted by regulating the temperature of the substrate 1 (a sample), and the the workpieces are etched. Since the rates of changes by a temperature of the etching rates of a plurality of the workpieces (such as an insulating or conductive film 3 and a coating film 4 such as a photoresist) on the surface of the substrate 1 each differ, the temperature of the substrate 1 is regulated in a process in which the surface of the substrate 1 is plasma-etched in a decompression atmosphere, thus controlling the etching rates of a plurality of the workpieces. That is, the both etching rates can be brought to the same extent or only at least one kind of a certain material can be etched selectively.

Title: Briquetting method for reduced iron pellet
Inventor: TSUZUKI KOJI
IPC: C22B1/14
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To form briquettes chargeable into an iron making furnace, such as blast furnace and to effectively utilize iron oxide dust without imparting cost effectiveness by pressure forming the reduction roasted pellets of the iron oxide dust at and under a specified temp. and pressure. SOLUTION: The reduced iron pellets which are the residue after recovery of valuable metals and are formed by subjecting the dust contg. the iron oxide, i.e., iron and steel dust together with a carbonaceous reducing agent are heated to >=700 deg.C in an N2 atmosphere and are charged into metal molds. The pellets are then press molded under a pressure of 200 to 300kg/cm<2> . The briquettes sized 40mm diameter × 20mm produced by the method exhibit crushing strength of 35 to 49kg at 700 deg.C and about 50 to 74kg at 900'C. The briquettes are thus usable as an iron source of a high grade which has a decreased possibility of breakage during handling or after charging into an iron making furnace.

Title: Motion vector detector and fluctuation corrector for image
Inventor: EKUSA HIROSHI
IPC: H04N9/77
Filed: 1990-11-14
Abstract: PURPOSE:To derive a motion vector approximated to a hand-shaking vector by simple calculation by setting a weight coefficient at every detection area, and deciding the motion vectors for the whole picture by utilizing the weight coefficient. CONSTITUTION:The influence of the motion vector of a mobile material is not given to the motion vectors for the whole picture because the weight coefficient of a center detection area is zero. The motion vector of the mobile material 18 is detected in areas (V3, V6, V7, V10, V11, and V15). Since the weight coefficients of the areas V6, V7, V10, and V11 out of them are zeros, no influence is given to the motion vectors for the whole picture. No remarkable influence is given since the values of the areas V3 and V15 are set at small values relatively by weighted mean. The center of the picture shows the motion of a subject, and it can be expected that motion at the end of the picture shows the motion of hand-shaking, therefore, the weight coefficient more higher compared with other part is set at the end of the picture. Thereby, it is possible to derive the motion vector approximated to the hand-shaking vector by the simple calculation.
