To provide a fluid flow rate detection device which can be evaluated as adequate from a medical point of view. The velocity of a fluid flowing through a luminal organ in vivo is to be obtained. V(r, &#x3b8;)=w&#xb7;V+(1&#x2212;w)&#xb7;Vis calculated to obtain a calculated value V(r, &#x3b8;) of the flow rate regarding a component of the fluid in the direction perpendicular to the ultrasonic beam direction. Here, the weight w is a value proportional to the distance d from the wall on one side of the organ at least when the distance is smaller than a predetermined distance from the wall on the one side, and the weight is a value proportional to the distance d' from the wall on the other side of the organ at least when the distance is smaller than a predetermined distance from the wall on the one other side.

Fluid flow rate detection device

A method for producing a fluid trap for an instant film assemblage, which method can produce an environment-friendly trap easily and at low cost, is disclosed. A plate-shaped paper material having a uniform width and a uniform thickness is passed through a clearance formed between a pair of rollers. The plate-shaped paper material is compressed at width-directional opposite end portions thereof such that a thickness of the paper material gradually decreases from a central portion thereof toward opposite ends thereof, and at the same time, the paper material is cut along a longitudinal direction thereof to a predetermined width. Thereafter, the paper material is cut along the width direction thereof at predetermined intervals with respect to the longitudinal direction thereof, thereby producing the trap.

Method for producing fluid trap for film assemblage

The present invention is directed to developer solution trapping chips for use in a peel-apart type instant film unit, wherein the developer solution trapping chips are manufactured by cutting a continuous chip blank obtained by contour extrusion, which sets quickly, exhibits little deformation when wound on a reel, and produces a limited amount of swarf in cutting operation. The developer solution trapping chips are made of glycol-modified polyester and have preferably a trapezoidal or semicircular cross section.

Instant film packs

An instant photo film pack to be loaded in a pack holder is constituted by a box-shaped pack case which contains stacked self-developing photo film units of a peel-apart type. The pack case has an exposure opening formed in an upper wall thereof and a passage opening formed with a front wall thereof. A pressure plate is disposed in the pack case, and provided with a pair of lateral walls so as to separate an inside of the pack case into upper and lower chambers. Each of the photo film units includes a photosensitive sheet contained in the upper chamber. An image receiving sheet is contained in the lower chamber. A withdrawing sheet has an edge connected with the photosensitive sheet. A developing solution pod is disposed on the withdrawing sheet, for containing developing solution. A mask sheet has an edge connected with the withdrawing sheet. A mask opening is formed in the mask sheet. The image receiving sheet is disposed behind the mask opening to close the mask opening, and secured thereto in a peelable manner. The improved instant photo film pack is constituted by the pack case and the pressure plate being plastic molded pieces. A biasing force transmission member is disposed on a bottom wall of the pack case, for transmitting the biasing force of a spring member on an inside of the pack holder to the pressure plate, to push the pressure plate toward the exposure opening.

Instant photo film pack

This invention relates to an NF-.kappa.B activity inhibitor which contains alkaloids originated from a plant belonging to the genus Stephania of the family Menspermaceae, derivatives thereof and salts thereof, as the active components, to an agent for use in the treatment and prevention of diseases upon which the NF-.kappa.B activity inhibiting action is effective and to an inhibitor of the expression of related genes. Since said active components exert an action to inhibit transcription of DNA having an NF-.kappa.B recognition sequence by inhibiting the activity of NF-.kappa.B, the drug of the present invention can inhibit expression of genes of certain substances such as cytokines, inflammatory cytokine receptor antagonists, MHC class I, MHC class II, .beta.2 microglobulin, immunoglobulin light chain, serum amyloid A, angiotensinogen, complement B, complement C4, C-myc gene, HIV, SV40, CMV, adenovirus and the like, so that the inventive drug is useful in treating and/or preventing various diseases in which these substances are taking roles.

NF-KB activity inhibitor

An instant photo film pack contains has a light-tight bag, which contains a stack of ten photo film units of a self-processing type in a light-tight manner. The light-tight bag has a bag component constituted by one belt-shaped sheet, and a tab projecting from the bag component. The bag component is formed by attaching one portion to another in a peelable manner. When the tab is pulled in one direction, attachment of the bag component is peeled, to strip the bag from the photo film units in a form of the belt-shaped sheet.

A film unit for an instant camera includes a photosensitive sheet connected with a leader sheet. A carrier sheet is partly superposed on the leader sheet and bonded thereto at one end, and a drawer member is bonded to the leader sheet, at one end, near the bonding portion between the carrier sheet and the leader sheet. The other end of the drawer member is projected outside the camera body when the film unit is loaded in the camera. An image receiving sheet to which an image formed on the photosensitive sheet is transferred, is connected to the other end of the carrier sheet. When the projecting end of the drawer member is pulled after exposure, the leading end of the leader sheet is pulled to be inserted between a pair of pressure rolls and to be projected outside the camera body by way of the bonding portion between the drawer member and the leader sheet, with the drawer member being peeled off the leader sheet thereafter. When the projecting end of the leader sheet is subsequently pulled, the photosensitive sheet is superposed on the image receiving sheet, and at the same time a developing solution bag containing therein developing solution is pinched by the pressure rolls and broken to permit the developing solution to flow between the photosensitive sheet and the image receiving sheet. The bonding portion between the drawer member and the leader sheet is of V-shape.
