Leaf paper bundling apparatus

ABSTRACT OF THE DISCLOSURE There is a leaf paper bundling apparatus that winds a tape around a periphery of a stack of leaf paper at a portion other than that which is held by a bundling device, which performs cutting and thermal adhesion of the tape ends to bundle the leaf paper, and which comprises a tape winding device that winds a tape around a periphery of a stack of leaf paper at a portion other than that which is held by the bundling device, clamping devices that, after the tape is wound, tightens in the vicinity of a tape winding portion of the leaf paper, and a tape tightening device to apply tension to the tape. The clamping devices have first and second clamping members that contact the top and bottom leaves of paper of the leaf paper that is to be bundled, and clamp, and each of the clamping members has a pair of contact edges that are positioned on either side across the width of the leaf paper at the portion where the tape is wound, and a tape thermal bonding pad is inserted in between the contact edges of one of the clamping members when the leaf paper is clamped by the first and second clamping members,

Pressure sensor, has semiconductor chips corresponding to strain measuring devices, where each strain measuring device is arranged in semiconductor chip, respectively, and each semiconductor chip is attached to diaphragm

The pressure sensor (100) has a metallic diaphragm (20) for receiving pressure, and strain measuring devices forming a Wheatstone bridge. Each strain measuring device outputs an electrical signal, which corresponds to a deformation of the diaphragm, if the diaphragm is deformed by the pressure. Semiconductor chips (21b, 21c) correspond to the strain measuring devices, where each strain measuring device is arranged in the semiconductor chip, respectively. Each semiconductor chip is attached to the diaphragm. An independent claim is also included for a method for manufacturing a pressure sensor.

Method for preparing (F-18)-fluoride ion.

A process for producing [F-18]-fluoride ion suitable for the production of radiofluorinated organic compounds comprises: (i) bringing [O-18]-enriched water containing [F-18]-fluorine ion into contact with a stronger acidic cation exchange resin to remove impurity cations, (ii) bringing the water thus treated into contact with a weakly basic anion exchange resin, and (iii) eluting and collecting the [F-18]-fluoride ion which has adsorbed onto the weakly basic anion exchange resin. The [O-18] enriched water which is recovered in step (ii) can be recycled, without prior purification, for use in step (i) of the process.
