Title: Production of drawn tape
Inventor: ITO MINORU
IPC: D01F6/62
Filed: 1990-06-14
Abstract: PURPOSE:To obtain a drawn tape excellent in heat shrinkage resistance and winding appearance by blending a specific polyethylene terephthalate and specified polypropylene in a specific proportion, melting the blend, extruding the melt into the form of a film, quenching and solidifying the formed film, then cutting the solidified film into the form of a tape, drawing the cut tape and heat-treating the drawn tape under relaxing conditions. CONSTITUTION:Polyethylene terephthalate having 0.7-1.1, preferably 0.8-1.0 intrinsic viscosity in an amount of 60-95wt.%, preferably 65-90wt.% is blended with 40-5wt.%, preferably 35-10wt.% polypropylene having 1-10g/10min, preferably 1.5-8g/10min melt flow rate and the resultant blend is melt extruded into the form of a film at 260-290 deg.C, quenched and solidified, then cut into the form of a tape, drawn at 60-110 deg.C in the take-off direction at 30-90% draw ratio based on the total draw ratio, subsequently drawn at 150-180 deg.C at 4-8 times based on the total draw ratio and further heat-treated at 180-220 deg.C under relaxed conditions of 10-30% to afford the objective drawn tape suitable as weaving yarn for base fabrics of carpets, etc.

Title: Heating apparatus for semiconductor manufacturing apparatus
Inventor: IMAI HITOSHI
IPC: H01L21/31
Filed: 1986-07-02
Abstract: PURPOSE:To perform the heat treatment of silicon wafers uniformly without depending on the position of a quartz boat, by inserting the quartz boat, on which the silicon wafers to be heat-treated are mounted, through one side of a quartz tube, so that the boat passes through the tube to the opposite side of the quartz tube. CONSTITUTION:When a quartz boat 2 is inserted in a quartz tube 5, a pushing rod 6 is operated and inserted through a hole 5g of a quartz cap 5c. When the boat 2 is slowly inserted in the quartz tube 5 through an inserting hole 5a, silicon wafers 3a mounted on the tip part of the boat 2 are inserted earlier than silicon wafers 3b mounted on the rear part. The temperature of the wafers at the tip part is increased earlier. When the boat 2 is taken out of the quartz tube 5, the boat 2 is moved in the same direction as the inserting direction with the rod 6. At this time, the wafers 3a are taken out of the quartz tube 5 earlier than the wafers 3b, and the temperature of the wafers 3a is decreased. Thus the heat treatment of the wafers 3a and 3b is uniformly carried out without depending on the position of the boat 2.

Title: Ribbon cassette
Inventor: NAKAYAMA TAKUMI
IPC: B41J32/02
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To prolong the lifetime of an ink ribbon while sustaining clear printing power by arranging two pairs of drive roller and driven roller for ink ribbon symmetrically on the left and right sides so that they can be loaded in a printer while being turned over and the print region can be modified and enlarged. SOLUTION: An ink ribbon 2 being led in by means of a drive roller 3b and a driven roller 3a and stopped in the center of a cassette housing 1 is passed sequentially through the gap between a drive roller 3d and a driven roller 3c and carried through a ribbon outlet 1a to the outside of the cassette housing 1 before being passed in front of a print head 5. When a ribbon cassette is loaded to a printer while being turned over, a slide cam functions to shift the driven roller 3c thus shifting a switching mechanism for preventing the driven roller 3c from pressing the drive roller 3d. Consequently, the driven roller 3a is shifted to release press contact with the drive roller 3b and the driven roller 3c begins to press the drive roller 3d.

Abstract: PURPOSE:To prevent a symbol and a character string which is already inputted from overlapping with each other by providing a document updating means which inserts the symbol into a blank area formed by moving document information, and stores information on the inserted symbol and the moved document information in a document storage means. CONSTITUTION:The document information and information on a symbol extending over plural rows or plural columns are inputted to an editing means 82 through an input means 81. The symbol information and document information from the editing means 82 are stored in a document storage means 83.
