Title: Method for extracting feature of image contour part
Inventor: NAKAYAMA HIROSHI
IPC: G06K9/48
Filed: 1987-01-30
Abstract: PURPOSE:To easily and at high speed attach a feature code on the picture element of a contour part, by expressing the feature code as the travel direction of a tracking point at the time of tracking a contour. CONSTITUTION:A binary image is raster-scanned, and firstly, for example, a white picture element point which changes from the white picture element to a black picture element is found, and ¦P+DELTA¦P is set as an initial value setting the white picture element point as a contour tracking start point (first remarking point) S. In such a case, the coordinate itself of the contour tracking start point is set on the ¦P, and a unit vector in a direction opposite to a scan direction is set on the DELTA¦P. Four linked picture elements are investigated in a clockwise direction from the four linked picture elements having 90 deg. left-ward against a direction moved to the remarking point, and when an investigated point is the white picture element, movement to that point is performed, and when it is the black picture element, the four linked picture elements adjacent to the right are investigated in order, and after determining the tracking point, a directional code corresponding to the DELTA¦p which represents the travel direction is registered. In such a way, it is possible to accelerate the detection of the feature in the contour part.

Title: Container box for clean room
Inventor: YOSHIMURA YASUSHI
IPC: B65D85/38
Filed: 1986-02-03
Abstract: PURPOSE:To reduce dusts to be adhered to the outer surface of a box by providing a heater for the outer surface of the box for preventing dusts from being adhered to form a space which does not almost contain dusts near the outer surface of the box, thereby reducing the dusts by the space. CONSTITUTION:A power source 22 is turned ON to generate heat from an electric heating wire 20 to raise the temperature of the outer surface of an upper cover 16. When the cover 16 arrives at a predetermined temperature, it is detected by a temperature regulating mechanism in the power source 22 to control a current supplied to the wire 20. A wafer 12 may be contained in a wafer cassette 18 in this state, or contained before the power source is turned ON. Since a temperature difference occurs between the outer surface temperature of a container box 10 and the environmental temperature in this state, a larger kinetic movement than a low temperature side is applied to dusts in the air near the outer surface of the box from medium gas molecules, and the dusts are moved by a thermal migration phenomenon from the vicinity of the outer surface of the box toward separate low temperature region. Thus, it can reduce dusts to be adhered to the outer surface of the box.

Title: Bag with prohibitive function from unsealing
Inventor: NAKAMURA TOSHIO
IPC: B65D33/34
Filed: 1995-02-08
Abstract: PURPOSE: To secure a sufficient prohibitive function from unsealing even when a bag is folded deep and sealed, by providing prohibitive lines against unsealing at the position separated farther than the flap length from the end of the bag opening side of the front side sheet and at the nearby position of the bag opening of the flap. CONSTITUTION: When an unfair person scrapes up the free end 132 of a flap 120 by a claw or the like and holds it to try to peel off the flap 120 from the first sheet piece 112, the first sheet 112 is pulled toward the flap 120. Accordingly, the first prohibitive line 154 against unsealing is remarkably deformed or broken and hence an unsealing trial trace is left. When a bar material like a pencil is inserted in the breadthwise direction of the bag from a ring-form part 156 which is formed by folding back the side of flap 120 of the bag 110 onto the first sheet piece 112 and further this is pressed to the bag bottom side to try to unseal the position where the flap 120 is stuck to the first sheet piece 112, from the upper side of bag, the second prohibitive line 158 against unsealing is deformed or broken and hence a trace of unsealing trial is left.

Title: Facsimile equipment
Inventor: OGUSHI HIROSHI
IPC: H04N1/00
Filed: 1990-01-31
Abstract: PURPOSE:To automatic the changeover between the manual reception mode and the automatic reception mode by switching the manual reception mode and the automatic reception mode with an output signal from a means detecting whether or not a card is loaded to a loading section. CONSTITUTION:The facsimile equipment is provided with a means 15 detecting whether or not a card 7 is loaded to a loading section 8, and the reception mode and the automatic reception mode are changed over by an output signal from the detection means 15. Since the data memorandum card 7 is carried frequently in place of a telephone memorandum at a visit, the facsimile equipment is set automatically to the automatic answering mode and mistake of forgotten changeover is decreased. Since a telephone memorandum is required frequency in the case of making a phone call or facsimile transmission at return home from the visit, the data memory card 7 is loaded naturally to a main body 1, resulting that the resident mode is set. Thus, mistake of the automatic answering mode at the resident is reduced.

Abstract: PURPOSE: To provide a resin film useful as a packaging material or the like and excellent in surface smoothness, dimensional stability at high temperature, and the like by a method wherein temperatures and circumferential speeds of rolls are specified, when a longitudinally drawn thermoplastic resin film is heat-treated by a multi-stage roll.

Thus, the film 1 is heated to the temperature T 1 . Heating rolls 4, 5 are set at stepwise- elevated temperatures. The circumferential speeds of rolls are so set that they are high enough to prevent the film between rolls from looseness and that the ratio of  the circumferential speed difference between a preceding roll and the following roll to the circumferential speed of the preceding roll is largest for the most upstream pair of rolls. Thus, the film 1 is subjected to heat treatment at slowed down pace.
