Title: Forming method of polyimide pattern
Inventor: TANAKA TAKESHI
IPC: G03F7/42
Filed: 1993-03-18
Abstract: PURPOSE:To form the polyimide pattern capable of easily releasing a posi-type photoresist film by heating a substrate with this film formed thereon before releasing this posi-type photoresist film. CONSTITUTION:Firstly, a substrate, after being coated with a polyimide precursor, is pre-baked to form a polyimide precursor film. After coating this film with a posi-type photoresist, the substrate is pre-baked to form a posi-type photoresist film to be selectively exposed. Next, after or simultaneously with the development of the posi-type photoresist, the lower layer polyimide precursor film is selectively removed to be patterned using the posi-type photoresist film as a mask. Next, the substrate whereon the posi-type photoresist film and the polyimide precursor film are formed is heated thereby enabling the release property of the posi-type photoresist to be improved. Finally, the patterned polyimide precursor film on the substrate is to be heat-treated so as to convert the polyimide pattern.

Title: Blood filter
Inventor: HOSOKAWA AKIRA
IPC: A61K35/18
Filed: 1988-03-12
Abstract: PURPOSE:To reduce the damage of blood corpuscles and to make a leucocyte removing rate and an erythrocyte recovery rate excellent, by constituting a filter of nonwoven fabric using a synthetic fiber having predetermined monofilament fineness and a profile cross-section whose surface area increase rate is a specific value or more. CONSTITUTION:The fineness of the monofilament of a synthetic fiber constituting a blood filter is set to 0.25 denier or less, pref., to 0.1 denier or less and the cross-section of the monofilament has an odd-shape and the surface area increase ratio F=l/(4pis)1/2(wherein l is the average outer peripheral length of the monofilament cross-section and s is the average cross-section of the monofilament cross-section) is 1.15 or more. This synthetic fiber is in an opened state. Since the synthetic fiber constituting the blood filter has the profile cross-section, an increasing surface area increase ratio is 1.15 or more, pref., 1.30 or more as compared with a round cross-sectional fiber and the surface area increase ratio of 1.15 or less is not pref. because the enhancement of the removal rate of a leucocyte is less as compared with the round cross-sectional fiber. By this method, even when the diameter of a fiber is not made too small and a filling rate is not enhanced, the contact surface area of the fiber with a leucocyte is increased, and a leucocyte removing rate and an erythrocyte recovery rate are made excellent.

Title: Faraday cup
IPC: G01T1/29
Filed: 1992-03-17
Abstract: PURPOSE:To prevent measuring of an implant current from being affected by gas if generated inside a Faraday cup during ion implantation. CONSTITUTION:An ion beam 1 is implanted through a coil-shaped Faraday cage 7 into a subject 4 to be implanted with ions, and the ion current is measured by an ammeter 6. Gas generated during implanting is expeled from gaps in the coil 7. Secondary electrons are trapped by a magnetic field that the coil 7 generates, and are thereby not emitted outside. Therefore, even if the subject to be implanted with ions is one that readily emits gas, such as a resist- equipped semiconductor wafer, the gas is promptly expeled from the gaps in the coil, so the rate of lowering of the degree of vacuum can be reduced and the ion beam current can be accurately measured.

Title: Vapor-phase graft polymerization
Inventor: MIYASHITA TOSHIYASU
IPC: C08F291/00
Filed: 1981-04-20
Abstract: PURPOSE: To carry out a graft polymerization in an industrially advantageous manner, by premixing a radical polymerization initiator with a solid trunk polymer and effecting the graft polymerization of one or more monomers under conditions in which at least one of said monomers can participate in the reaction in the form of vapor.  
     CONSTITUTION: A polymer having methyl, methylene and methine groups and being substantially solid at a graft polymerization temperature (e.g., polyethylene; polyphenylene oxide being excluded) used as a trunk polymer is premixed with a radical polymerization initiator (e.g., benzoly peroxide, used in an amount  of 0.1W30pts.wt. per 100pts.wt. trunk polymer). Next, this mixture is mixed  with one or more radical-polymerizable compounds (e.g., vinyl chloride) to effect  grafting onto the trunk polymer under conditions in which at least one of said  radical-polymerizable compounds exerts a vapor pressure lower than the saturated vapor pressure at the polymerization temperature. This process can provide a high graft efficiency of the monomer and trunk polymer, and is advantageous in economy.
