Abstract: PURPOSE: To obtain the high purity title compound, a stable and widely used glycolipid surfactant, in high yield, by the ester exchange of glycolipid methyl ester which is obtained by methanolysis and methylation of low viscosity sophorolipid.  
     CONSTITUTION: Sophorolipid, a mixture of the compounds of formula I(R 1 WR 4  =H, COCH 3 ) and formula II, is added to the polyhydric alcohol of formula III (R 5 =H, CH 3 ; R 6 =H, C 1W5  alkyl; m=1W6) and formula IV (R 7 =R 6 ; n=m). The obtained mixture of sophorolipid and a polyhydric alcohol is subjected to the methanolysis and the methylation with CH 3 OH in the presence of acid to give methyl[(2'-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] alkanoate or alkenoate. Treatment of this compound with ROH (R=C 2W20  alkyl) gives the compound of formula V (R 3 =H, CH 3 ; R 4  is a C 12W16  hydrocarbon group when R 3 =H, or R 4  is a C 11W15  hydrocarbon group when R 3 =CH 3 ).

IPC: A61M25/00
Filed: 1989-01-30
Abstract: PURPOSE:To prevent a sticking phenomenon due to self-stickiness by providing fine unevenness having a specific height due to melt fracture at the time of extrusion molding to the surface of a polyurethane tube. CONSTITUTION:As polyurethane, thermoplastic polyurethane possible in melt extrusion and containing no substance harmful to a human body such as polyether segmented polyurethane or polyester segmented polyurethane is used. By setting an extrusion molding condition to a predetermined range at the time of the molding of the tube by melt extrusion, melt fracture is generated and the height of the fine unevenness of said fracture is set to 5-100mum. By this method, even when the outer or inner surfaces of the tubes are brought to a mutual contact state, said surfaces become a point contact state and tack due to self-stickiness can be prevented.

Title: Quick and highly sensitive measuring method
Inventor: ISHIKAWA EIJI
IPC: G01N33/543
Filed: 1989-01-28
Abstract: PURPOSE:To perform a quick and highly sensitive measurement characterized by simple operation by obtaining the bonded body of a composite that is composed of an antigen material or a specific antibody and two kinds of active components, dissociating the composite from a carrier, and measuring the material. CONSTITUTION:There are the following methods. One method is as follows: a composite is formed of an antigen material or a specific antibody to be measured such as serum, pulpa liquid and saliva, an active component wherein functional groups are bonded and a component wherein labels are bonded. The composite is bonded to a carrier. The other method is as follows: an active component to which a functional group is bonded and an active component to which a label is bonded are added into the liquid to be checked, and a composite is formed under the conditions which are used in ordinary antigen-antibody reaction. The composite is bonded to a carrier. Then, the liquid to be measured and the carrier are separated by an immunological measuring method using a carrier. After the carrier is cleaned, a material having the same reacting part as that of a functional group, which is associated with the bonding of the composite and the carrier, is added. The composite is dissociated from the carrier without decomposition. The dissociated composite is measured by the method which measures a label that is introduced in the active component. In this way, the highly sensitive measurement can be performed, and the operability can be improved.

Title: Low noise amplifier and communication portable terminal using the amplifier
Inventor: IRIE KIYOSHI
IPC: H04B1/3822
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce parasitic capacity which additionally occurs and to suppress the deterioration of the ability of a transistor by eliminating a potential difference between the emitter terminal and the sub-terminal of the transistor. SOLUTION: A received high frequency signal inputted from an input terminal 1 is amplified and it is outputted from an output terminal 2. An input matching circuit 3 and an output matching circuit 4 are lumped constant circuits constituted of first capacity 3a, inductance 3b and second capacity 3c and they convert impedance into desired one. The emitter terminal 8b and the sub-terminal 8c of the transistor 8 are grounded and the potential difference between the terminals 8b and 8c is eliminated. Parasitic capacity which additionally occurs in the transistor is reduced and the deterioration of the ability of the transistor is suppressed. Since the deterioration of the ability of the transistor is suppressed, emitter resistance (feedback resistance) is eliminated and therefore current may become unstable. It is desirable to add an active feedback bias circuit at that time.

Abstract: PROBLEM TO BE SOLVED: To protect the part of an interlayer insulation layer covering the edge of a first semiconductor layer against electrostatic breakdown strength by setting a wafer-like semiconductor device in an ion implanter while directing the ion beam such that the part of the interlayer insulation layer covering the edge of the first semiconductor layer is shaded by a second semiconductor layer. SOLUTION: A water-like semiconductor device 1 is set in an ion implanter while directing oppositely to conventional direction before implanting ions. Consequently, the direction of ion beam relative to the surface of a substrate 1 is reversed. More specifically, the part (a) of an interlayer insulation layer sandwiched by the edge of first and second polysilicon layers 2, 4 is shaded by the second polysilicon layer 4. Consequently, intrusion of impurities into that part (a) is blocked by the silicon layer 4 itself and electrostatic breakdown strength is protected against lowering at the part (a) sandwiched by the edges.
