IPC: D06B23/18
Filed: 2002-01-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for obtaining cotton having excellent bulkiness.  <P>SOLUTION: Cotton is housed in a vessel 1. The pressure of the interior of the vessel 1 is reduced to ≤1.3 kPa in absolute pressure. A high-temperature water 5 at ≥120°C is introduced into the vessel under the reduced pressure. The pressure in the vessel is raised, for example, to about 490 kPa to 1.2 MPa in the absolute pressure by the introduction of the high-temperature water. The state is kept for a prescribed time, e.g. 2-5 min. The pressure in the vessel 1 is gradually lowered, for example, to about 200-490 kPa in the absolute pressure when the state is kept because the heat of the high-temperature water 5 is taken by the vessel 1. After the reduction of the pressure, the high- temperature water 5 in the vessel 1 is discharged from a drain pipe 8 to the exterior of the vessel 1. At the time, the valve of the drain pipe 8 is opened, and the pressure in the vessel 1 is reduced to the atmospheric pressure. The resultant cotton is taken out, and the taken out cotton has excellent bulkiness because the cross section of each cotton fiber is swelled and has a nearly circular shape.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-01-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ignition device of an internal combustion engine that prevents erroneous ignition at energization of a primary winding without providing a diode for back-flow prevention.  <P>SOLUTION: This ignition device 1 for an internal combustion engine restricts a change rate per unit of time of a primary current 21 that flows in a primary winding 33 to a small value, by driving and controlling an igniter 17 by an ignition command signal 72 after conversion of a waveform with a substantially trapezoid shape. Accordingly, induced voltage of reversed polarity generated on both ends of a secondary winding 34 by energization of the primary winding 33 does not reach a voltage value that can generate spark discharge on an ignition plug 13. As a result, the ignition device 1 can prevent erroneous ignition at the engine at a timing different from actual one (that is, at energization of the primary current) and also can prevent occurrence of spark discharge at energization of the primary winding 33 without providing a diode for back- flow prevention.  <P>COPYRIGHT: (C)2003,JPO
