Title: Method for operating ring fine spinning frame, when doffing is stopped, and method for cutting yarn on doffing
Inventor: YAKUSHI MAKOTO
IPC: D01H5/32
Filed: 2003-05-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for operating a ring fine spinning frame on the stop of doffing, by which a yarn can be cut in a short yarn end state, even when the yarn has a large count.  <P>SOLUTION: This method for operating the ring fine spinning frame on the stop of doffing is characterized by disposing a draft device capable of changing a draft rate independently from the driving of a spindle-driving system and changing the draft rate of the draft device into a larger draft rate than a draft rate on a spinning time without changing a twist count, before forming an inclined winding on a bobbin on the stop of doffing, thus operating the spinning frame on the stop of the doffing. The draft rate can be increased by enlarging a rate for lowering the rotation rate of a back bottom roller. Since the thickness of the yarn is reduced without changing the twist count of the yarn constituting the inclined-wound yarn, the end yarn in an end yarn-cutting portion can be cut in a short yarn end state, when the doffing is carried out with a doffer.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Device and method for correcting camera-shake and device for detecting camera shake
Inventor: CHO SENKICHI
IPC: H04N5/232
Filed: 2003-05-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide an inexpensive small-sized device which can perform camera-shake correction that is precise and excellently responsive.  <P>SOLUTION: Input images YC1 and YC2 are contracted step by step over a plurality of steps and a scanning block in obtaining an amount of local movement at an upper layer level is established by utilizing an amount of global movement roughly obtained by using a contracted image at a lower layer level. Thus, it becomes possible to establish correlation with an image in a reference block set on a first image without enlarging the scanning block to be set on a second image so much. By allowing reduction in the size of the scanning block, the probability for a plurality of identical or similar patterns to exist in the scanning block becomes small, and inconveniences that an image in the reference block and an image in the scanning block are decided to be matched at a wrong position are suppressed. Also, since a range to be scanned becomes small, an amount of operation decreases and the responsiveness of camera-shake correction is improved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: B05C11/00
Filed: 2003-05-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide an instrument for simply measuring the applied quantity of a liquid applied to a flat plate.  <P>SOLUTION: The instrument has a shape similar to a watch glass and a dimension gripped in one hand or both hands. An outer peripheral face of the watch glass is a liquid contact face 3 and contacts an oil 2 applied to the flat plate 1. An inner peripheral face of the watch glass is a scale face 4 and provided with a scale 5. The watch glass is made of glass, has a uniform refractive index, is placed on the flat plate 1 on which the oil 2 is applied and lightly pressed so as to bring a region having a local minimal value of the outer peripheral face 3 (the most protruding point of the outer peripheral face 3) into contact with the flat plate 1. A contact area between the outer peripheral face 3 and the oil 2 is changed by a applied thickness of the oil 2. As the applied thickness of the oil 2 increases, the contact area between the oil 2 increases. There is a regular relationship between the applied thickness and the contact area. The applied thickness (the applied quantity) of the oil 2 is found by measuring the contact area of the oil 2. A diameter can substitute for the contact area.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
