Inventor: MATSUMURA HIDEKAZU
IPC: B09B3/00
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To improve the draining property of decomposition water by lessening the clogging of water flow holes. SOLUTION: An agitating section 43 has a function to agitate microorganism carriers 31 and crude refuse and is adapted to scrape the microorganism carriers 31 and crude refuse near the water flow holes 16a of punching metals 16. The agitating section 43 is so inclined as to act force upward from a horizontal direction on the microorganism carriers 31 and crude refuse near drain holes 16a for the decomposition water. As a result, the microorganism carriers 31 and crude refuse deposited above the drain holes 16a for the decomposition water are scraped by the agitating section 43, by which the clogging of the drain holes 16a for the decomposition water is prevented.  Further, the opening planes of the plural drain holes 16a for the decomposition water are formed as circular arc planes concentric with the loci of rotation of the agitating section 43 and, therefore, the agitating section 43 turns while having the same clearances as the opening planes at all times. The clogging of the drain holes 16a for the decomposition water is thus effectively lessened over the entire area of the opening planes.

Title: Sleeve capture device suitable for usage for load beam
Inventor: TOREISHII MAIKURU HAAGEN
IPC: G11B5/60
Filed: 1990-11-27
Abstract: PURPOSE: To eliminate the need for compression according to a gap between trapped members by displacing a sleeve contact surface of a second trapping tab member by a length smaller than a thickness of a lead wire sleeve from a line generally specified by sleeve contact surfaces of a first trapping member and a third trapping member. CONSTITUTION: A lead wire sleeve 22 is arranged under a trapping tab 62, being passed upward through a hook part of a trapping tab 64, being passed under a trapping tab 66 and being finally passed upward through a hook part of a trapping tab 68. The trapping tab 68 has a curved contact surface 70 to be in contact with the lead wire sleeve 22, and the tab 66 has a flat contact surface 72 to be contact with the lead wire sleeve 22. And a maximal displacement between the contact surface 70 and the contact surface 72 is smaller than the total 76 of the diameters of the sleeve 22 and the lead wire 30. Therefore, a vertical position of the lead wire sleeve 22 varies with a lengthwise position of the lead wire sleeve 22 along an end edge of a load beam 60. Thus, a proper displacement is obtained for swaging without a process to compress a trapping tab.

Title: Ink, applying method thereof and applying device
Inventor: YAMAMOTO YASUMASA
IPC: C09D11/38
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain an ink capable of suppressing the blot of the ink without requiring any pretreatment of a medium for recording or an installation of a special mechanism for a printer, and useful for an ink jet recording method, etc., by including charged particles mainly consisting of a coloring agent and a substance having an opposite charge. SOLUTION: This ink contains (A) a medium for dispersion, (B) charged particles consisting mainly of a coloring agent [e.g. a charge based on the ionic character of a dispersing agent used for dispersing the coloring agent into the component (A)] and (C) a substance having an opposite charge to the component (B) (e.g. having a feather like or a particle like shape). On applying the ink on a medium for recording by loading the ink on an ink jet printer, etc., since a shearing rate is high at the ink discharge part, the component (B) and (C) are separated to reduce the viscosity of the ink for a good discharge. On the impact of ink droplets at the medium for recording, since the shearing rate is reduced, an attracting force works between the components (B) and (C) for restraining the motions between each other to increase the viscosity of the ink before a blot spreads so as to be able to suppress the blot of the ink.
