Abstract:
According to this invention, a nucleic acid purification instrument whereby it is possible to prevent dispersion of a mist thai causes contamination upon discharge of a solution is realized. A pressurizing nozzle is allowed to come into contact with a nucleic acid capturing column such that the sealing member is compressed. An aspiration fan is operated and thus the air in a closed channel flows toward the bottom part of a liquid receiving tank and then toward the aspiration fan as a result of a partition board. The inside of the nucleic acid capturing column is pressurized using tho pressurizing nozzle such that a solution in the nucleic acid capturing column is discharged and gravity-fed to the lower part of a liquid receiving tank. When the liquid volume m ihe nucleic acid capturing column becomes very small, the discharged solution is mixed with air so as to be formed into a mist and flows toward the aspiration fan and is captured by a protection filter so as not to bo discharged outside the closed channel.
Abstract:
A shaft seal packing exhibits high sealability at the time of initial assembly and also exhibits, even after the packing is retightened, excellent sealability by an increased seal surface pressure obtained through an effect of pressing and by self-sealability obtained through an effect of fluid pressure. A shaft seal structure for a valve includes a body for a valve, a valve shaft, a valve disc disposed within the body so as to be rotatable or capable of ascending and descending, a valve shaft seal chamber having the valve shaft axially attached thereto, a shaft seal packing that is attached to the shaft seal chamber and comprises annular packing bodies stacked and substantially V-shaped in cross section, with stacked layer faces on the inner-diameter side of the packing bodies brought into tight contact with one another and stacked layer faces on the outer-diameter side of the packing bodies formed with prescribed gaps between the adjacent stacked layer faces. In the shaft seal structure for a valve, a tightening load on the packing bodies and fluid pressure are converted to a force in the diametrical direction owing to inclined angles of stacked layer faces on the inner-diameter side to attain a seal by a surface contact between the inner peripheral surface on the inner-diameter side and the outer peripheral surface of the valve shaft on a sliding side, and a lip part on the outer-diameter side is pushed and spread owing to the gaps to attain a seal by a line contact with the shaft seal chamber on a fixed side.
Abstract:
According to this invention, a nucleic acid purification instrument whereby it is possible to prevent dispersion of a mist that causes contamination upon discharge of a solution is realized.A pressurizing nozzle 12 is allowed to come into contact with a nucleic acid capturing column 35 so as to closely adhere to the sealing member 36 in a manner such that the sealing member 36 is compressed. Then, an aspiration fan 52 is operated and thus the air in a closed channel (surrounded by a nucleic acid capturing column retention block 37 and a liquid receiving tank 54) flows toward the bottom part of a liquid receiving tank 54 and then flows toward the aspiration fan 52 as a result of installation of a partition board 55. The inside of the nucleic acid capturing column 35 is pressurized using the pressurizing nozzle 12 such that a solution in the nucleic acid capturing column 35 is discharged The discharged solution is gravity-fed to the lower part of a liquid receiving tank 54. When the liquid volume in the nucleic acid capturing column 35 becomes very small, the discharged solution is mixed with air so as to be formed into a mist. The solution exists in a mist form in the middle of an airflow formed by the aspiration fan 52 and the mist flows toward the aspiration fan 52. Then, the mist comprising the solution is captured by a protection filter 51 so as not to be discharged outside the closed channel.
Abstract:
It is an object of the present invention to further stabilize the efficiency of isolating nucleic acid concerning an apparatus for isolating nucleic acid. The present invention relates to an apparatus for isolating nucleic acid, the apparatus being provided with a meshed solid substance for binding nucleic acid. By employing the meshed solid substance for binding nucleic acid, fluid resistance can be reduced upon allowing a sample that includes nucleic acid to pass the solid substance for binding nucleic acid, while securing solid-phase volume that is sufficient for binding a large amount of nucleic acid. Consequently, even when the sample is allowed to pass the solid substance for binding nucleic acid at a high aspiration/dispense speed, force added to the solid substance for binding nucleic acid is small and the solid substance for binding nucleic acid is almost undistorted. The average pore size of the mesh that has an influence on the efficiency of binding nucleic acid by the meshed solid substance for binding nucleic acid is also almost unchanged. Therefore, the optimum state of the efficiency of isolating nucleic acid can be maintained.
Abstract:
This invention relates to an apparatus and a method for manufacturing a member which makes a part of a car body of an automobile or the like by mash-seam welding a plurality of blanks. Standby areas (B) are provided at both right and left sides of an welding area (A) to/from which a seam welding machine (130) moves forward/backward, and a lapping device (100) for overlapping respective end portions of blanks (W1)(W2) and a temporary clamping device (80) for temporarily clamping the blanks (W1)(W2) are disposed on two transfer tables (70) which are sent from the standby areas (B) to the welding area (A) by turns. When the blanks (W1)(W2) with these end portions overlapped one another and temporarily clamped are sent to the welding area (A) by the transfer table (70), the blanks (W1)(W2) are permanently clamped by a permanent clamping device (180) and thereafter, subjected to a mash-seam welding by upper/lower electrode rollers (142)(148) of the seam welding machine 130. At this time, upward reactive force which acts on a cylinder (146) for pressing the upper roller (148) downwardly is received by a frame structure (134) which is installed in the welding area (A).

Abstract:
A vehicle sunshade device has guide rails disposed on both sides of an opening formed in a roof of a vehicle. The guide rails each has a guide groove having in turn a straight portion oriented longitudinally and extending substantially horizontally and an inclined portion continuous with the straight portion. Sliding members are slidably fitted in the groove, the sliding members being provided on sides of a sunshade for opening and closing the opening, being made larger in longitudinal length than in thickness and being elastically deformable in vertical directions. A vertical gap in the inclined portion at least at an intermediate portion thereof is made larger than a vertical gap in the straight portion of the guide groove. In the case of the vehicle sunshade device having front and rear sunshades, sliding members each having a portion for abutment at a front upper portion are provided on both sides of a rear sunshade at a front portion thereof. And side plates are provided on both sides of a front sunshade which each have at a rear end thereof an abutment portion adapted to be brought into abutment with the portion for abutment of the sliding member so as to push the rear shade rearward. An inclined portion is provided below the abutment portion in such a manner as to incline forwardly downwardly so as to push the portion for abutment of the sliding member downwardly toward the rear when the sunshade approaches the fully opened position, and a lower edge extending continuously from a front end thereof toward the front so as to prevent the upward movement of the sliding member.
