摘要： A pressure type flow rate control apparatus (1) for controlling flow rate of a fluid maintains an upstream side pressure P1 of an orifice at more than about twice a downstream side pressure P2. In addition to an orifice-forming member (5) the apparatus includes a control valve (2) provided at the upstream side of the orifice, a pressure detector (3) provided between the control valve and the orifice, and an operation control device (6) for calculating a flow rate Qc from the detected pressure P1 of the pressure detector as Qc=KP1 (K being a constant) and issuing a difference as a control signal Qy between a flow rate command signal Qs and the calculated flow rate Qc to a drive unit of the control valve. The orifice upstream side pressure P1 is adjusted by opening and closing the control valve, thereby controlling the orifice downstream side flow rate.

摘要： Disclosed is a method of purifying a mature peptide with a free N-terminus group from a mixture of peptides comprising the mature peptide and immature end-capped peptides. The peptides are bound to a solid-phase support and are produced by solid phase synthesis. The mixture is contacted with a linker comprising a functional group at each terminus. The functional group at one terminus has the structure --SO.sub.2 --CH.sub.2 --CH.sub.2 --X, wherein X is an activated carbonate group which reacts selectively with N-terminus of the mature peptide to form a urethane linkage. The functional group at the other terminus is a thiol protected with an acid labile group. After cleaving the peptides from the solid support and thiol protecting group with acid, the mature peptide is separated from the mixture by forming a covalent bond between the liberated thiol and a solid support. Treatment with base cleaves the mature peptide from the linker to give a purified mature peptide.

摘要： A bending device for an endoscope operates the bendable portion on the front end side of the insertable portion of the endoscope to bend by moving back and forth an operating wire which is inserted in a coil sheath housed within the insertable portion to connect the bendable portion and an operation portion for bending on the rear end side of the endoscope. The bending device prevents a relative looseness between the coil sheath and the operating wire by fixing the coil sheath at its end on the bendable portion side so as not to rotate around its axis and controlling rotation of the coil sheath at the other end on the operating portion side around the axis thereof within a limit.

摘要： A flexible carbon material is produced by carbonizing a composite material comprising carbon fibers having an average length of 6 to 50 mm and a binding agent. Carbon lumps are derived from the binding agent and are dispersed in a matrix of the carbon fibers so as to restrain a plurality of the carbon fibers while yet permitting relative slippage to occur as between the carbon fibers and carbon lumps such that the carbon fiber material exhibits a flexibility ratio D/d of not greater than 200 (where D is the diameter of curvature of the carbon material, when bent, just before breakage, and d is the thickness of the carbon material). The carbon fibers and lumps are preferrably present in an amount of from 5 to 50%, and 5 to 70% by volume, respectively, based upon the total volume of the carbon material.
