Filed: 1992-11-09
Abstract: PURPOSE:To always obtain stable limiter torque even when temperature change, humidity change, or speed change occurs 'in environment by arranging two magnets by confronting with each other so as to hold the magnetic plate of a limiter gear between two planes. CONSTITUTION:When the limiter gear 13 is driven rotatably, a magnetic attractive force generates in both upper and lover planes of the magnetic plate 14 being rotated integrally with the gear 13 by first and second magnets 17, 20.

Title: Packing material with at least one weak line and method and device for producing the same
Inventor: HERUMUUTO TSUIIRUKE
IPC: B31F1/00
Filed: 1993-11-05
Abstract: PURPOSE: To enable easy opening with a method as quiet and careful as possible to leave no reminder of packing material by letting a weakened line have weak points of variable material strength. CONSTITUTION: A packaging material 21 has a weakened line 23, which consists of a plurality of equally spaced weak points 25 and 27 alternately and sequentially disposed by web 29. Weak points 25 are designed differently from those 27 and the former extend longer than the latter, but the both are made similar in the width. If necessary, however, widths of more than one weak points are variably chosen, too. The weakened line 23 becomes strong against bending stress crossing longitudinal direction of the line 23 by web 29 between weak points 25 and 27. At the same time, weak points 25 that do not cut through the packaging material 21 but just embossed assure article packaging to be airtight and hygienically satisfied until the weakened line 23 is very quietly broken for the purpose of opening a pack composed of the packaging material 21.

Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent accidents and to improve the reliability of automatic opening/closing operation by disabling the automatic opening/closing of door while the stage of dehydration is just under progressing in a washing machine provided with an automatic door opening/closing device. SOLUTION: When a user pushes a pedal 60 with a foot in the state of closing a door 20, a door motor 31 is driven, a rotary panel 34 is turned forward, a 1st projection 35 is engaged with a 1st tooth 51, and a rear half member 22 of door 20 is gradually carried up. Besides, when the user pushes the pedal 60 with the foot in the state of opening the door 20, the door motor 31 is driven, the rotary panel 34 is turned backward, and the rear half member 22 of door 20 is gradually dropped down. In this case, while the stage of dehydration is progressed, even when inputting the automatic opening/closing request of door 20, this request is ignored and an initial state is recovered later. Thus, since the automatic opening/closing of door is disabled during the progress of dehydrating stage, accidents can be prevented and the reliability of automatic opening/ closing operation can be improved.

Title: Method of coating
Inventor: IKEDA RIKIO
IPC: H01L21/027
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce the deviation of pattern dimensions due to variations in thickness of a coating when patterns are formed by spin coating on a substrate having a step. SOLUTION: When a substrate having a step of less than 100 microns in width is coated by spin coating, the coating is set to a thickness corresponding to a point shifted +0.01 to +0.10 in terms of the period from a peak of a standing-wave curve Sw that represents pattern dimensions varying with variations in thickness of the coating, so as to reduce the deviation of pattern dimensions. In the case of a substrate having a step of greater than 100 microns, on the other hand, the coating is set to a thickness corresponding to a point shifted +0.10 to +0.30 in terms of the period from a peak of the standing-wave curve Sw, so as to reduce the area in which pattern formation is inhibited.
