Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To easily eliminate ashes from a filter by providing pressure changing means by which pressure on the upstream or downstream side of the filter in an exhaust passage is rapidly changed when it is judged that the regeneration of the filter is completed by which particulate scavenged is burnt. SOLUTION: When each filter 5 is regenerated, particulate scavenged in each filter 5 is burnt by heat of exhaust gas, however, calcium, an oxide of phosphate, a sulfide or the like in the particulate may not be burnt, but deposited in each filter 5 as ashes. Then, when an engine speed is increased to some extent and a particulate scavenging amount in each filter 5 is gradually decreased and becomes a predetermined amount or below, a first control valve 4a is opened and closed, thereby pressure on the downstream side of each filter 5 in an exhaust passage 3 is rapidly changed, so that an exhaust gas amount passed through each filter 5 is rapidly changed. Hereby, ashes in each filter 5 are separated by the sudden changes of pressure difference and a flow and delivered to a downstream side.

Filed: 1987-09-30
Abstract: PURPOSE:To obtain an intermediate tone image with high resolution and excellent image quality in a wide variable density range, by forming a heat generating element so that the element is separated at both end parts thereof and the separate parts are joined at a central part of the element. CONSTITUTION:A heat generating element applied to a thermal recording head for a thermal transfer printer is connected between a pair of electrodes 2, 3. The element 1 is formed in such a shape that the element is separated into a plurality of parts at both end parts thereof, the separate parts are connected to the electrodes 2, 3, and the separate parts are joined in a body at a central part of the element. For instance, the element 1 is formed in the shape of X. With the element 1 thus shaped, current density is highest at the central part of the element. With the element 1 disposed on each diagonal line of a rectangular picture element, a melted region of an ink is spread in a horned pincushion-like pattern from the center of heat generation of the character X crossing the entire are of the dot, so that a wide variable density range can be obtained, and resolution can be enhanced. In addition, recorded density characteristics have a relatively linear property, so that a controllable wide variable density range can be obtained without any overload on a thermal recording head, and the useful life of the head can be prolonged.

Title: Method for retrieving similar document and device therefor
Inventor: MASE HISAO
IPC: G06F17/30
Filed: 1994-10-14
Abstract: PURPOSE: To register a document with ease and eliminate the influence of character misrecognition on retrieval precision by using the same character recognition part for both registering the document in a data base(DB) and retrieving the document. CONSTITUTION: Documents inputted to a document image input part 2 are classified roughly into two kinds, and one is DB registered documents 1 which are stored in a text DB7 and an image DB8 and the other is original documents for similar document retrieval and documents 9 for retrieval. Since the character recognition part 4 used when the documents are registered in the text DB7 is the same as the character recognition part 4 used when the similar document retrieval is performed, the tendencies of character misrecognition are similar to each other. Namely, even if a character desired to be retrieved in a similar document fails to be recognized, the possibility that the character fails to be recognized in text data in the text DB7 is high, so the precision of matching of a key word does not decrease so much.  Therefore, the retrieval precision which depends little upon character recognition precision can be obtained.

Filed: 1984-11-26
Abstract: PURPOSE:To prevent a reduction in the efficiency of sending air by equipping a multiblade impeller or the inside wall of a casing with a flat and toroidal rectifying plate crossing the rotational axis of an impeller at a right angle. CONSTITUTION:A centrifugal blower comprising of a spiral casing 1, a multiblade impeller 2, and a motor 3 for rotating is equipped with a flat and toroidal rectifying plate in such a state as the plate is fitted on the periphery of the impeller. Accordingly an air flow which strikes against a rotary disc 4 to deflect in reverse return direction comes into contact with the rectifying plate 5 to correct its flowing direction, and is discharged from a blowout port 8 in a direction perpendicular to the rotational axis 9 of the impeller 2. Thus the swirling motion of a suction air flow can be securely checked, and a reduction in the efficiency of sending air can be therefore prevented.
