Title: New protein, its production and use thereof
Inventor: KOBAYASHI YUKINAO
IPC: G01N33/566
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a new protein having affinity for osteoclastogenesis inhibitory factor(OCIF) and specifically binding thereto and to provide a method for producing the protein. SOLUTION: This new protein is obtained by solubilizing a membrane fraction of mature osteoclast and purifying the fraction by using an OCIF immobilized column. The protein has M.W. of about 140,000 (SDS-polyacrylamide gel electrophoresis under nonreducing condition). A substance for inducing and/or inhibiting a bone absorption activity of osteoclast can be screened by using the new protein or a cell expressing the protein. The new protein or the screened substance can be used for study, a diagnosing reagent, a medicine, or the like, for bone dysbolism.

Filed: 1990-10-16
Abstract: PURPOSE:To efficiently manufacture a shape steel free from material abnormality and having a good shape, in the inlet side or outlet side of a hot finish rolling mill by jetting cooling water to rapidly cool the surface of a flange, and thereafter executing heating to complement recuperating and temp. rising. CONSTITUTION:At the time of manufacturing a thin H-shape steel or the like by hot rolling, in the inlet side and/or outlet side of a hot finish rolling mill, the surface of a flange is temporarily cooled to a temp. exceedingly lower than the Ar1 point, and after that, recuperating and temp. rising are executed by holding heat. A heat cycle constituted of both stages of cooling and recuperating is repeated for >= two times to reduce its residual stress. At this time, cooling water is jetted on the surface of the flange in the cooling stage to promote cooling. Furthermore, in the recuperating stage, heating for complementing its temp. rising is executed till its temp. reaches a one in the vicinity of the AC1 point except the recuperating after the final cooling. In this way, the shape steel free from the generation of web waves, free from the generation of deterioration in toughness and small in residual stress can efficiently be obtd.

Abstract: PURPOSE:To rapidly solidify the fibrous sol at the time of producing an inorg. fiber by the sol-gel method and to efficiently spin a gel fiber with simple equipment without causing adhesion, etc., by bringing the fibrous sol during or after spinning into contact with a basic material to gel the sol. CONSTITUTION:Water, catalyst (e.g., hydrochloric acid), etc., are added to an organometallic compd. (e.g., tetraethoxy silane) to cause hydrolysis and polymerization, and a viscous soln. is prepared. The viscous soln. is discharged from a spinning nozzle to produce a fibrous sol, and the sol during or after spinning is brought into contact with a basic material (e.g., ammonia and methylamine) and gelled. The obtained gel fiber is then roasted to obtain an inorg. fiber. In addition, when the basic material is added to the sol before spinning, a reticular polymer is obtained, and the stringiness of the sol is prevented.

Title: Ink jet recording apparatus and head unit employed therefor
Inventor: NAKAMURA HIROTAKE
IPC: B41J2/175
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus and a head unit employed therefor, which creates a state of being full of ink without leaving air bubbles within an ink jet head at the time of initial introduction of ink. SOLUTION: In the interior of an ink jet head 1, introduction liquid of higher viscosity than that of ink is filled before the introduction of the ink. The introduction liquid in the ink head 1 is sucked from a nozzle port by a purge mechanism, and then the ink is introduced into the ink jet head 1 through an ink filter member 7. At this time, air bubbles are hard to occur by turbulence or the like due to the high viscosity of the introduction liquid, further, its flow velocity becomes slow in breaking through a filter member 7. Thus, air bubbles become hard to adhere also to the wall surface of a manifold 3.
