At the time of drawing the blood continuously from the vein of the patient by means of a catheter and measuring the concentration of a specified constituent part contained in the blood automatically and continuously for long hours, the sample liquid and two sorts of correcting liquids (standard liquid I and base liquid) are sucked by a single sampling nozzle in prescribed order and are supplied to the measuring section through a common channel. Each of the liquids are diluted with a buffer solution at the identical rate with the manifold in the measuring section, are separated from one another through the interposition of air layers among them, and supplied to a sensor. The outputs of the measured sample liquid from the sensor are corrected by the outputs of each of the neighboring measured correcting liquids in succession and are displayed as measured values. In the blood-drawing section, there is used a double-current catheter having the first and second catheter arrangements which are constructed so as to be incorporated directly into the tube pump.

An object of the invention is to provide a decomposing system for polyisocyanate residues that is capable of suppressing reaction of polyisocyanate residues with high temperature and high pressure water to allow smooth start-up of the operation, and a start-up method for the decomposing system for the polyisocyanate residues. The decomposing system is used for hydrolyzing the polyisocyanate residues to polyamine using high temperature and high pressure water, comprising a hydrolyzer, a water feed pipe connected to the hydrolyzer, a residual feed pipe connected to the water feed pipe, a solvent feed line for filling an organic solvent in a solvent filling portion of the residual feed pipe, and a solvent draining line. Upon start-up of the operation, the organic solvent is previously filled in the solvent filling portion via the solvent feed line and the solvent draining line, first, and then, the high temperature and high pressure water is fed from the water feed pipe to the hydrolyzer. Then, the organic solvent is fed from the residual feed pipe to the water feed pipe, first, and then, the polyisocyanate residues are fed thereto.
摘要:
A product design support method and system are disclosed in which assuming that a globally distributed commodity is disposed of as a waste product by different recycle methods in different regions or countries, the recycle cost and environmental load accrued by different processing methods are quantified using the product design information thereby to assist in the design improvement. The product information and the regional recycle characteristics are input to determine the recycle method by region. Further, the recycle cost/environmental load by region are quantified based on the product design information using the basic unit information of the recycle cost and environmental load by region.

The problems of the invention are to establish a modeling resin composition excellent in shape retention and dewaxing properties in the skillful system which comprises a urethane resin easy if thermal decomposition, a plasticizer, and a wax or waxy component and a dewaxing method suitable for models made form the composition and to enhance the strength of a mold in the low temperature range wherein dewaxing is carried out. According to the invention, a mold is produced by applying a primary layer consisting of plural fireproof coating layers among which epoxy silicone layers are laid and a backup layer consisting of plural thick coating layers on the surface of a resin model made by curing a two-component reaction curing type urethane liquid resin (F) which consists of a multifunctional polyol component (A), a multifunctional polyisocyanate component (B), a plasticizer (C), a wax or waxy component (D), and hollow resin balloons (E), preheating the obtained composite in a low temperature range within 60 to 120° C. during 2 to 8 hours to conduct initial dewaxing of removing 5 to 50% by weight of the resin model, raising the oven temperature gradually, and conducting the heating of the resulting composite in a medium temperature range of 150 to 500° C. during 2 to 5 hours and then the firing thereof in a high temperature range of 500 to 1000° C. during 2 to 5 hours.
摘要:
A disc drive includes a main body, a disc tray movable with respect to the main body between a loading position for loading an optical disc and an eject position, and a chassis on which a rotational drive mechanism for rotating a loaded optical disc is provided. The chassis is pivotally provided with respect to the main body about a pivotal axis near the rear end of the chassis so that the front end thereof can be displaced between a lowered position when the disc tray is ejected and a raised position for placing the optical disc on the rotational drive mechanism when rotating the optical disc. The disc drive prevents the chassis and/or the optical disc rotational drive mechanism from interfering or colliding with other elements of the disc drive.
