An improvement for a self-balancing shielded bipolar ionizer (U.S. Pat. No. 6,002,573), which uses pressurized air or nitrogen to increase performance, extend the operating distance range, and reduce cleaning frequency. An air assist assembly is inserted into the ion generation cavity, which directs pressurized air or nitrogen past the electrodes. In applications where little natural airflow exists, air assist technology is particularly useful. Ions are blown toward the target. This directs the ions to where they are needed, and delivers ions faster. Useful operating distances are increased. Faster delivery minimizes ion losses due to recombination. Furthermore, pure pressurized air protects the electrodes from impurities in the environmental air. Less chemical growth affects electrode performance. Hence, the ionizer exhibits more stable performance, plus the need for electrode cleaning is minimized.

The object of the present invention is provision of a surface protection sheet for laser processing to be applied to the surface on the opposite side of the laser beam irradiation face, which can protect the surface of an application object, and does not allow easy development of a dross during laser cutting processing. According to the present invention, a surface protection sheet 1 for laser processing to be applied to the surface on the opposite side of the laser beam irradiation face 2a of a workpiece 2 during a cutting process by irradiation of a laser beam 6 on the workpiece 2 is provided, which contains a substrate layer and an adhesive layer formed on one surface of the substrate layer, wherein the substrate layer is made of a resin material having a melt viscosity measured based on JIS K7199 (1999) at 290° C. of not more than 200 Pa·s, and has a thickness of 0.01-0.12 mm.

Disclosed is a fusion protein Slit2D2-HSA formed by fusion of a Slit2D2 polypeptide and a human serum albumin HSA, and use thereof for the manufacture of a medicament for prophylaxis and / or treatment of sepsis, and the said fusion protein Slit2D2-HSA retains the pharmacological activities of Slit2 in inhibition of neutrophil migration and treatment of sepsis, and has an improved stability, prolonged half-life and improved therapeutic effect of sepsis. Compared with protein of Slit2, the polypeptide of Slit2D2 has a smaller molecular weight which is much easier to be purified and separated in preparation and used in the development of drugs.

The present invention provides a method for manufacturing a quantum dot color filter. The method for manufacturing a quantum dot color filter of the present invention, after forming a blue sub-pixel part of a quantum dot color filter by applying a photolithographic operation to a transparent organic photoresist material, applies hydrophobicity treatment to the transparent organic photoresist layer so as to make use of hydrophobic characteristics so formed to help coat green quantum dot curable paste and red quantum dot photoresist sequentially on corresponding areas to form, in sequence, a green quantum dot curable paste layer and a red quantum dot photoresist layer located thereon, and then applies photolithographic operations to subject portions of the red quantum dot photoresist layer to etching for forming a green sub-pixel part and a red sub-pixel part of the quantum dot color filter, whereby compared to the conventional ways of manufacturing a quantum dot color filter, at least one round of photolithographic operation can be saved to greatly simplify the manufacturing process, reduce cost, and improve manufacturing efficiency, and it only needs to develop one type of quantum dot photoresist so as to greatly reduce difficulty and cost of development.

A process of producing a maraging steel includes melting a steel of a defined composition, casting the molten steel to obtain a steel ingot, hot forging the steel ingot at a forging ratio of at least 4, then soaking the forged piece one or more times to keep the forged piece in a temperature range of 1100-1280° C. for 10-100 hours, and then plastic working the forged piece. A process of producing a maraging steel of another defined composition includes casting the molten steel to obtain a steel ingot with a defined taper, a defined height to diameter ratio and a defined flatness ratio and plastic working the steel ingot so that the size of a nonmetallic inclusion is 30 μm or less expressed as the diameter of a circle of circumference equal to the perimeter (“circumference”) of the inclusion.
