摘要:
The purpose of the present invention is to provide methods for producing recombinant polyclonal immunoglobulins using recombinant DNA techniques, which provides constant supply of immunoglobulin preparations with minimum risk of infection. A method of the present invention comprises the following steps: (1) isolating a plurality of types of genes from cDNAs derived from tissues or cells expressing immunoglobulins, said genes encoding a plurality of types of polypeptides respectively, and said polypeptides containing a plurality of types of immunoglobulin variable regions respectively, and preparing mixture of the genes; (2) preparing a plurality of types of recombinant vectors into which a plurality of types of genes are introduced respectively by contacting said mixture of the genes with vectors, and preparing mixture of the recombinant vectors; (3) preparing a plurality of types of transformants into which a plurality of types of recombinant vectors are introduced respectively by contacting said mixture of the recombinant vectors with host cells, and preparing mixture of the transformants; and (4) culturing said mixture of the transformants, and obtaining mixture of polypeptides from the transformants culture, wherein said polypeptides contain a plurality of types of immunoglobulin variable regions respectively.

摘要:
A method of manufacturing a tandem-type thin film photoelectric conversion device includes the steps of forming at least one photoelectric conversion unit (3) on a substrate (1) in a deposition apparatus, taking out the substrate (1) having the photoelectric conversion unit (3) from the deposition apparatus to the air, introducing the substrate (1) into a deposition apparatus and carrying out plasma exposure processing on the substrate (1) in an atmosphere of a gas mixture containing an impurity for determining the conductivity type of the same conductivity type as that of the uppermost conductivity type layer (33) and hydrogen, forming a conductivity type intermediate layer (5) by additionally supplying semiconductor raw gas to the deposition apparatus, and then forming a subsequent photoelectric conversion unit (4).
摘要:
A semiconductor integrated circuit has a first clock distributing circuit and a second clock distributing circuit. The first clock distributing circuit is configured for distributing a first clock within a first region in a semiconductor chip. The second clock distributing circuit is configured for distributing a second clock within a second region in the semiconductor chip. The second region is located within the first region.

A window regulator to be disposed in a vehicle comprises: a first frame disposed on one side of the longitudinal direction of a door and extending in the directions for a door glass to go up and down; a second frame disposed on the other side of the longitudinal direction of the door and extending in the upward and downward directions of the door glass; an upper frame disposed to span the upper portion of the first frame and the upper portion of the second frame; a wire tensed in an annular shape along the first frame, the upper frame and the second frame and having a return portion for a backward run in the first frame; a first wire fixing member disposed on one side of the longitudinal direction of the door glass and retained by the return portion of the wire to move along the first frame; a second wire fixing member disposed on the other side of the longitudinal direction of the door glass and retained by the wire portion to move along the second frame; and a drum disposed on the inner side of the door panel of the door and wound with a portion of the wire for moving the annularly tensed wire back and forth when it is turned.
摘要:
A method for indexing and coding element information of at least one biological element provided on a microarray chip thereby identifying the microarray chip. Some of the element spots arranged on the microarray chip are used as index spots to be selectively provided with at a detective colorant. By doing so, the microarray chip is specified, and the element information as well as experimental information of the chip is automatically managed.

When etching a silicon layer 210 with a processing gas containing a mixed gas constituted of HBr gas, and O2 gas and SiF4 gas and further mixed with both of or either of SF6 gas and NF3 gas by using a pre-patterned mask having a silicon oxide film layer 204 inside an airtight processing container 102, high-frequency power with a first frequency is applied from a first high-frequency source 118 and high-frequency power with a second frequency lower than the first frequency is applied from a second high-frequency source 138 to a lower electrode 104 on which a workpiece is placed. Through this etching process, holes or grooves achieving a high aspect ratio are formed in a desirable shape at the silicon layer.
摘要:
An optical head, able to reduce thermal stress generated in an optical lens mounted on a bobbin, having a bobbin formed with a center hole and an optical lens mounted on the bobbin via a thermal expansion adjustment member 40 formed with an opening. The optical lens has a substrate formed by an optical material different from the bobbin in coefficient of thermal expansion. The substrate has a convex part functioning as a convex lens and a flat part positioned around the convex part. The flat part is fixed to the thermal expansion adjustment member so that the convex part fits in the opening. The optical lens is placed so that a center axis of the convex part or an extension thereof passes through the center hole of the bobbin and the center axis of the convex part coincides with a center hole of the bobbin.
摘要:
An optical head has achromatic lenses which a blue or blue-violet laser beam from a laser diode strikes, object lenses for condensing the laser beam passing through the achromatic lenses on an optical disc, lens holders and for holding the achromatic lenses and the object lenses so that their optical axes coincide, and actuators and for moving the lens holders in the focus direction and/or tracking direction of the optical disc. The lens holders are fixed to each other and the lenses are moved as one part by the actuators.
