Title: Production of human interleukin 5
Inventor: TSUJIMOTO MASAFUMI
IPC: C12N15/24
Filed: 1989-06-22
Abstract: PURPOSE:To perform industrial mass-production of the subject compound in high yield by culturing an animal cell containing introduced gene of active human interleukin 5 (hIL-5) and separating the supernatant of the cultured product by column chromatography, etc. CONSTITUTION:An animal cell (A) is produced by introducing pdKCR-hIL-5 gene-dhfr which is a cloned hIL-5 chromosome gene. The cell A is cultured in a serum-containing medium and then cultured in a IL-5 producing medium free from serum. The supernatant liquid of the produced culture product (B) is precipitated with ammonium sulfate to obtain a fraction (C) containing hIL-5. The fraction C is subjected successively to a dye column chromatography, an anion exchange resin column chromatography and a column chromatography with a carrier having hydrophobic functional group. The resultant purified fraction (D) is purified again by gel-filtration column chromatography to obtain human interleukin 5.

Title: Liquid crystal display device
Inventor: ISHII AKIRA
IPC: G02F1/136
Filed: 1991-07-01
Abstract: PURPOSE:To improve the yield, to prevent OFF characteristics from deteriorating, and to improve the display quality by forming a black matrix and a color filter of the same dyeable resin and dyeing the black matrix in black. CONSTITUTION:Two transparent substrates are put on one over the other across a specific gap so that their surfaces where transparent picture element electrodes are provided face each other; and liquid crystal LC is charged between both the substrates and one of the transparent substrate is provided with the black matrix BM and color filter FIL. The black matrix BM and color filter FIL are formed of nearly the same dyeable resin and the black matrix BM is dyed in dark color such as black. In this case, the black matrix BM can be formed of one layer of the dyeable resin, so the surface flatness is good. Further, the black matrix BM and color filter FIL are formed of the same dyeable resin, so the difference in thermal expansion is equal, so the peeling and cracking of the color filter FIL or black matrix BM can be suppressed.

Title: Air-intake device for motorcycle and the like
Inventor: INOMATA FUMIO
IPC: F02M35/04
Filed: 1982-09-14
Abstract: PURPOSE:To prevent a flame trap and an air-cleaner element from being directly exposed to back-fires to aim at enhancing the life and durability of an air- intake device, by connecting an air-cleaner with a fuel supply device through a connecting pipe, and by forming a suction port in the air-cleaner, substantially perpendicularly to the surface of the flame trap. CONSTITUTION:Air taken from a suction part 13b is purified through an element 15, and is fed through a guide pipe 19 to a large volume chamber 17 from which air is fed to a carburettor 11. When a blow-back is brought about, the blow- back reversely flows into the air-cleaner 12 to which the chamber 17 is communicated, but does not directly touch a flame trap 16 and the purifying surface of an element 15 when it flows into the guide pipe 19 since the opening part 19d of the guide pipe 19 is substantially orthogonal to the flame trap 16 and the purifying surface of the element 15. Accordingly, the flame trap 16 and the element 15 are prevented from being contaminated by, for example, carbon, thereby the life and durability of the air-intake device are enhanced.

Title: Armouring material for construction
Inventor: AIZAKI SEIGO
IPC: E04F13/14
Filed: 1990-06-19
Abstract: PURPOSE:To prevent a channel, formed by injection of a sealing material from being conspicuous by forming a number of long, irregular jagged patterns on the surface of a rectangular plate body in the longitudinal direction of the plate body, and also forming channels of predetermined width at an irregular pitch in the longitudinal direction. CONSTITUTION:A long, irregular jagged pattern 13 is formed on the surface of an armouring material 1 for construction and extended in the direction of the material 1. Channels of width 6 to 12mm are extended in the direction perpendicular to the longitudinal direction from one side edge of the material 1 to the other and are formed at an irregular pitch of interval 2 to 10cm or so in the longitudinal direction. As a result, a channel 14 and another channel formed by injection of a sealing material 5 are extended in the same direction and have the same width and are therefore hard to be distinguished one from the other also because the intervals between the channels formed in the surface of the armouring material 1 for construction are irregular. In addition, the portion where the sealing material 5 is injected is even harder be distinguished because of the presence of the jagged pattern 13.
