摘要:
A twin wire sheet-forming apparatus for a paper machine having at least two fixed hydroextractors which have separate places for drainage to the hydroextractor side from places for dispersion of fibers. These hydroextractors are arranged alternately in the two wire loops, and have shoe blades, with a wedge shaped trough in a mid-portion of each shoe blade. The wires do not bend at a front leading portion of each shoe, yet do bend at the mid-portion or back portion of each shoe for generating a pressure pulse to disperse the fibers.

A shoe press apparatus of a paper machine for pressing wet paper through a nip includes a counter roll, and a shoe module disposed adjacent to the counter roll. The shoe module includes a cylindrical blanket, and a press mechanism disposed inside the cylindrical blanket, extending in a width direction of the cylindrical blanket and individually pressing a plurality of pressed portions formed on the cylindrical blanket along a traveling direction of the wet paper, toward an outer-surface of the counter roll so that the wet paper is pressed in the nip between the cylindrical blanket and the counter roll so that a pressure can be applied efficiently in response to a density required for paper solely by the shoe press apparatus.

In order to prevent the lowering of yield of fibers of stock which is pinched by two wires and being transferred, specific dewatering blades are disposed on each of the wires are used. Blade sets are disposed on two wires 1, 2 forming loops to pinch stock 7 and running therealong. The blades of one blade set are dewatering limiting blades 20, each having a plane portion 20a to support the wires 1, 2 and an inclined face 20b disposed on the wire entering side of said plane portion 20a and forming a space of a wedge shape facing the wire face and enlarging toward the upstream side in the wire running direction. The blades of the other blade set are dewatering blades 21, each having a plane portion 21a to support the wires 1, 2 and an edge 21b to scrape water toward the upstream side of said plane portion 21a. The plane portion 21a having the edge 21b is disposed opposite to the space of a wedge shape.

A dewatering instrument of a twin-wire former allows the angles at which the wires are wrapped around the dewatering blades to be adjusted even during operation so that pulsating pressure applied to the paper stock may be set appropriately according to the prevailing paper making condition. The respective dewatering blades of the dewatering instrument are supported by two support bodies, the first one of which is fixed and pivotably supports the blade, and the second one of which is movable to pivot the blade about the first. For example, the second support body may be a flexible tube which is inflatable and deflatable. When the blade is pivoted, the attitude of the land of the blade is changed so that the wrap angles of the wires with respect to the land of the dewatering blade are adjusted.

A heat insulating/sound absorbing material wherein the entire surface of an inorganic fiber mat is covered with a synthetic resin film or films and a method of producing the same. Front and rear surfaces of an inorganic fiber mat 12 as well as both side surfaces along a longer side thereof are covered with synthetic resin films 13, 14; both ends of the synthetic resin films in the direction of a longer side of the inorganic fiber mat 12 are extended from both ends in the direction of a shorter side thereof to thereby cover both end surfaces in the direction of a shorter side of the inorganic fiber mat 12; an adhesive is applied continuously or discontinuously along the direction of a longer side of film to a portion in the direction of a shorter side of the inorganic fiber mat whereby the inorganic fiber mat and the synthetic resin films, and a mutually opposing portion of the synthetic resin films are bonded so as to make air communicate through unbonded portions.

An improved multi-layer paper sheet forming system is disclosed, in which a degree of dispersion of fibers under the condition where a paper layer has been formed is large, thereby formation of a paper sheet is improved, moreover, bases of short wire cloth sections can be installed at the same level as a building floor and a complicated base of the shape of steps is not necessitated. The system comprises one endless felt loop and a plurality of short wire cloth sections disposed on the endless felt and provided with a dewatering instrument having, as dewatering elements, forming blades consisting of two zones, that is, a flat front half and a curved rear half. The short wire cloth section includes a forming roll having a large diameter and a breast roll having a small diameter, and the plurality of short wire cloth sections are disposed substantially at the same level. A movable return roll is equipped, which raises the felt between the adjacent short wire cloth sections so as to wrap around the short wire cloth so that an initial engagement point between the felt and the short wire cloth may come to an arbitrary position of the curved portion of the dewatering instrument existing at the upper portion of the short wire cloth section.

A propionate derivative having the general formula (I): ##STR1## wherein R.sup.1 is phenyl which may be substituted with one or more of the same as different substituents selected from the group consisting of halogen, methyl, methoxy, and nitro, R.sup.2 is alkyl, cycloalkyl, or alkenyl, R.sup.3 is alkylthio, cycloalkylthio, alkenylthio, phenylthio, or benzylthio which may be substituted with halogen or methyl and R.sup.4 is imidazol-1-yl or 1,2,4-triazol-1-yl, or the acid addition salt thereof or the metal complex thereof.This novel propionate derivative is suitable for use as an agricultural fungicide.
摘要:
The position of a face image within an input image is detected based on results from applying a plurality of weak classifiers in sequence to each of sub-images extracted from the input image. A decision whether to interrupt the sequence and reject a currently extracted sub-image is made based on the sum of a total of weighted decision values obtained up to the current point in the sequence and a total of potential weighted decision values obtainable from the remaining weak classifiers if the extracted sub-image were a face image.
摘要:
An estimation device estimates a hidden state of an estimation subject from an observable state in a manner of a time series. The observable state is observed from the hidden state of the estimation subject under a procedure that has a hierarchical structure, which includes the hidden state of the estimation subject, the observable state, and an intermediate hidden state therebetween. The estimation device includes an estimation subject hidden state predicting means, an intermediate hidden state predicting means based on the state transition structure of the hidden state of the estimation subject, an intermediate hidden state likelihood observing means, an intermediate hidden state estimating means, an estimation subject hidden state likelihood observing means, estimation subject hidden state estimating means, an intermediate hidden state predicting means based on the state transition structure of the intermediate hidden state, and the mixing means.
