Abstract: The purpose of the present invention is to provide a method for producing active GcMAF more simply and at a high yield. The present invention is a method for producing active GcMAF comprising a step for culturing host cells which are transfected with a VDBP expression vector in serum-free medium. This culture is preferably a suspension culture. In addition, this method for producing active GcMAF is also characterized by not requiring an enzyme treatment step for deglycosylation.

Abstract: A pinhole type imaging device of the present invention includes a pinhole type aperture stop which allows advancing of light ray into an optical system and imaging, and at least one lens which is attached to the pinhole type aperture stop. Accordingly, an imaging device where it is realized that all imaging results of subjects positioned at different photographing distances are sharp, which has a simple structure and can be reduced in size, and which is suitable for attachment or use in an information terminal such as a small-sized image pickup device, a portable phone (a cellular phone), or a mobile type computer, and an auxiliary device thereof.

Abstract: A first conductor is provided on an outer circumference of a central conductor with an insulator therebetween, a second conductor is provided on a concentric circle having the central conductor as its center and outside the first conductor with an insulator therebetween. A coaxial cable is formed by coating the outside of the second conductor, which is on the concentric circle having the central conductor as its center, with an insulating external coating. A DC voltage source is able to apply DC voltage having a predetermined voltage value between the first conductor and the second conductor such that the direct current flowing in the first conductor and the second conductor takes a desired value. A noise barrier zone formed by the electro-magnetic action of the desired current is formed in the part surrounded by the first conductor and the second conductor on the outer circumference of the central conductor.

Abstract: [Problem]To provide a coaxial cable which is able to shut off external noises and transmit clear images having no picture disturbance by noises without employing cable compensators over a long distance.

Abstract: An exposure apparatus having upper and lower ultraviolet rays irradiating devices which are vertically symmetrically disposed above and below a pattern-forming board having through holes therein, and upper and lower light-transmissible plates which are disposed spacedly from each other in a light path of the ultraviolet rays irradiated to the board so as to be vertically symmetrically disposed with respect to the board and horizontally movable, each of the ultraviolet rays irradiating devices having an electric discharge lamp and a reflection mirror and each of the light-transmissible plates having an uneven surface of a sawtooth section. With this arrangement, a proper photochemical reaction can be induced to the photoresist on the surface of the board and the inner wall surfaces of the through holes to thereby improve a working efficiency of a pattern forming process.

Abstract: An improved alignment table employable for an automatic exposing apparatus used for producing a number of printed wiring boards, wherein the alignment table is designed in a flat and hollow box-shaped configuration comprising an upper plate, a lower plate and side plates, the upper plate and the lower plate are provided with transparent plates at positions located opposite to each other, respectively, and the upper surface of the transparent plate placed on the upper plate is provided in the form of a mat surface.
