Abstract: PURPOSE:To obtain the composite membrane which obviates blood plasma leakage and maintains a sufficient gas exchangeability during use over a long period of time and has an excellent antithrhombotic property by packing the fine particles which has the higher hydrophilicity than the hydrophilicity of a hydrophobic porous membrane, the high affinity to a bio-compatibility-polymer to be coated and the grain size smaller than an average pore size into the pores and coating the same with the bio-compatibility-polymer. CONSTITUTION:The dispersion of the fine particles is admitted into the module of the artificial lung from an introducing port 13 or leading out port 14 for the 1st material transfer fluid thereof or an inlet 28 or outlet 29 for the 2nd material transfer fluid and the dispersion medium is filtered by a gas exchange membrane 2, by which the fine particles are packed into the pores of the hydrophobic porous membrane, i.e. the gas exchange membrane. After the dispersion medium is filtered, the dispersion medium remaining on the surface of the porous membrane is removed and is substd. with a solvent having a low solubility by washing fluid to dissolve the surfaces of the fine particles and to adhere and bond the particles. A good solvent to the fine particles is admitted into the module and is brought into contact with the particles, by which the fine particles are partly or completely dissolved and swollen to bond the fine particles to each other or to form the thin films to close the inside of the pores. The composite membrane is further brought into contact with the soln. is removed to coat the surfaces of the porous membrane which come into contact with the blood with the above-mentioned polymer.

Abstract: PURPOSE:To previously prevent the tip of a pile from being broken by measuring an interval between the outer peripheral surface of an excavating device and the inner peripheral surface of the ready-set pile, with distance-measuring sensors fitted on the outer periphery of the excavating device, and by finding the deformation of the pile tip from the change of the interval. CONSTITUTION:On the peripheral surface of an excavating device 2, a plurality of distance-measuring sensors 7 are fitted. Then, keeping pace with excavating work with the excavating device 2, measuring work for an interval C between the outer periphery of the excavating device 2 and the inner periphery of a ready-set pile 1, with the distance-measuring sensors 7 is executed. When stress is concentrated at the tip section of the ready-set pile 1 and it is extremely deformed and it is broken, then the interval C at the section is measured to be changed compared with the interval C at another section. When any damage of the ready-set pile 1 is forecast from the data of the interval C, then a pressing-in force is reduced, and the pile is settled with the best counterplan. As a result, deformation to be generated on the ready-set pile 1 is grasped, and at the same time, the settling work of the ready-set pile 1 can be executed.

Title: Current converting circuit
Inventor: NAGANO KATSUMI
IPC: G05F3/26
Filed: 1985-06-28
Abstract: PURPOSE:To attain the conversion of a comparatively minute input current of a high frequency with high accuracy by adding an operational amplifier which controls the potential of an input current terminal to a level equal to a reference potential and a bias current source to a current mirror amplifier. CONSTITUTION:The voltage of about 1.4V obtained from addition of the base- emitter voltage of both transistors TRQ1 and Q2 emerges between the input current side 1 and an emitter common junction point 3 of a main body circuit U1 equivalent to a current mirror amplifier by application of a power supply. Then said voltage is supplied to an operational amplifier A and amplified adversely. Thus the potential of the point 3 is set at -1.4V by said inverse output voltage. As a result, the voltage of 1.4V never emerges at an input current terminal T1 and this terminal T1 is kept at an earth level equal to the reference potential of the amplifier A. While the bias current of a desired level is applied to an input current Iin from a bias current source 4 to increase the cut-off frequency fT of the TRQ1-Q3 respectively. Then the frequency band of the circuit U1 is increased.

Title: Production for diaphragm for speaker
Inventor: EGUCHI TAROU
IPC: H04R7/02
Filed: 1980-10-09
Abstract: PURPOSE:To improve the adhesion strength to make it possible to use diaphragm using a polyolefin resin film, by molding the polyolefin resin film into a diaphragm form preliminarily and by forming a polar high polymar thin film immediately after activating the surface. CONSTITUTION:The film consisting of a polyolefin resin such as polypropylene and polyethylene is molded into a diaphragm form preliminarily, and a polar high polymer thin film is formed immediately after activating the surface by the corona discharge treatment or the like. Since the polyolefin resin film is molded into a diaphragm form preliminarily, slippage between the resin film and the polar high polymer thin film caused by different expansions, partial exfoliation of them, and the break of the high polymer thin film are prevented. Thus, the adhesion strength is improved to make it possible to use diaphragm using the polyolefin resin film.
