The claimed invention provides a bush and a bearing structure applied thereof. The bush slides along a guiding rod, and the bush is a circular body with an opening to cover the guiding rod over a semicircle. An included angle between the opening and the center of circle of the guiding rod is less than 180 degrees for installing the bush into the bearing structure of a sliding device. The bush is a guiding interface for guiding the sliding device sliding along the guiding rod, and the sliding device can slide along the guiding rod stably. The claim invention using a C-type bush assembled with the opening of the bearing structure not only makes the sliding device sliding stably, but also effectively reduces the capacity and the accumulative tolerance, and achieves effects of scaling miniaturization, accurate assembly and flexible design.

An automated test apparatus for risk and integrity testing for pharmaceutical filtration membranes, including at least the following components: a liquid injection inlet, a pump, a fluid pressure gauge, a gas pressure gauge, a plurality of solenoid valves, a plurality of membranes, a gas pressure regulator valve, a pharmaceutical product bottle, and a bubble generation bottle. The automated test apparatus of the present invention is controlled by computer software in connection with an automatic pharmaceutical synthesis apparatus for automated testing. In use of the automated test apparatus of the present invention, it needs only to start the operating system of the automated test apparatus for membrane risk and integrity test after the completion of the automatic pharmaceutical synthesis. The membrane risk and integrity test can be accomplished in a short time by measuring pressures of gas and liquid with pressure gauges deposed online concurrently.

Some aspects of the present disclosure provide for a method of accurately simulating variations in an operating parameter, due to processing variations caused by a multi-patterning exposure, by reducing the impact of layout sections having a large width and spacing. The method assigns a skew sensitive index to one or more sections of a multi-patterning layer formed with a first mask. Runlengths of the one or more sections are respectively multiplied by an assigned skew sensitive index to determine a skew variation for each of the one or more sections. The overall skew variation sum is then determined by summing the skew variation for each of the one or more sections. By separately determining the effects of processing variations (e.g., mask misalignment) for different sections of a multi-patterning layer, an accurate measurement of operating parameter variations is achieved.

Some aspects of this disclosure provide for electronic design automation (EDA) techniques that check whether individual blocks, such as transistors or other semiconductor devices, are connected to their correct power domains during design. In this way, the disclosed EDA techniques can limit or prevent overstress conditions applied to blocks and help to improve reliability of integrated circuits, when manufactured.

摘要:
The present invention discloses a method for preparing lipid-spacer-reactive functional group-peptide, whereinthe peptide consists of 3 to 16 amino acid residues in which at least one amino acid residue is lysine (Lys), the reactive functional group is a formula of —X—CO—Y—CO—, wherein X represents an oxygen atom or a nitrogen atom, and Y represents C1-6 alkylene which may be interrupted by one or two oxygen or nitrogen atom(s), the spacer is a hydrophilic polymer, and the lipid is phosphatidylethanoaminecarbonyl represented by the formula (I): R1 and R2 are the same or different and individually represent linear or branch C7-30 alkyl or linear or branch C7-30 alkenyl; which is characterized in that the reaction is carried out in a liquid phase and comprises the following steps of (a) firstly protecting Lys amino acid residue in the peptide through a protection group; (b) subsequently reacting the peptide with the lipid-spacer-reactive functional group; and (c) finally removing the protection group from Lys amino acid residue in the peptide.
