A linear transmission assembly having a lubricant recovery module is composed of a movable member having a chamber; a first oil wick inserted into the movable member and the chamber and having a first oil-absorbable portion and a first oil-dischargeable portion; an oil tank mounted to the movable member and having an oil room for storage of lubricating oil; a second oil wick mounted to the oil tank and having a second oil-absorbable portion and a second oil-dischargeable portion, the former of which extends into the oil room for contact with the lubricating oil and the latter of which reaches the chamber; and a third oil wick having a third oil-absorbable portion and a third oil-dischargeable portion, the former of which reaches the chamber and the latter of which does not contact the lubricating oil. Thus, the lubricating can be prevented from overspill and staining the linear transmission device.

摘要:
A precursor SnBZM for a dopamine receptor radiotracer and a method for preparing the same are revealed. The precursor includes a tributyltin group (Bu3Sn) that is easy to be replaced. Thus a dopamine receptor radiotracer 123I-IBZM can be produced at high yield rate by a substitution reaction of the precursor. At the same time, both the method for preparing the precursor SnBZM and a method for preparing a reference standard IBZM are simplified. Moreover, stability of each product is improved.
摘要:
A precursor used for labeling hepatocyte receptors and applied to radiotracers for imaging or pharmaceutical compositions for liver cancers is revealed. The precursor is a bifunctional compound. The bifunctional group includes a trisaccharide structure and a diamide dimercaptide (N2S2) ligand. The trisaccharide has high affinity to asialoglycoprotein receptors (ASGPR) on surfaces of hepatocytes while N2S2 ligand reacts with radioisotopes to form neutral complexes. Thus the precursor stays on surfaces of hepatocytes to provide radioisotope labeling or treatment effect of liver cancers.

摘要:
Disclosed herein are a device having an embedded heat spreader and method for forming the same. A carrier substrate may comprise a carrier, an adhesive layer, a base film layer, and a seed layer. A patterned mask is formed with a heat spreader opening and via openings. Vias and a heat spreader may be formed in the pattern mask openings at the same time using a plating process and a die attached to the head spreader by a die attachment layer. A molding compound is applied over the die and heat spreader so that the heat spreader is disposed at the second side of the molded substrate. A first RDL may have a plurality of mounting pads and a plurality of conductive lines is formed on the molded substrate, the mounting pads may have a bond pitch greater than the bond pitch of the die contact pads.
