Abstract: To provide a biochip, a biochip manufacturing method, an electrophoresis method, and an electrophoresis apparatus, by which the detection accuracy may improve, there is a biochip introducing a sample in band form into a sample separation passage, by a means for reducing the band width of sample, at which the sample is before being introduced in the sample separation passage in band form. The band of sample supplied to the sample separation passage is compressed, and the expansion by diffusion may be prevented, thus the detection accuracy may improve.

Abstract: A three-dimensional digital map prepared by an satellite or the like is stored in a first memory as a wide-area information. Narrow-area information obtained by a laser radar is stored in a second memory. Obstacle information on obstacles, such as high-voltage power lines, high buildings and cranes, is stored in a third memory. These three information are read out to generate virtual images on a see-through type display mounted on a helmet of a pilot so that the virtual images is superimposed on the actual field of vision.

Abstract: A glucan which is characterized by repeating units of [3)--Glc--(1.fwdarw.4)--Glc--(1.fwdarw.4)--Glc--(1.fwdarw.] wherein Glc represents alpha-D-glucopyranose residue.Said glucan may be prepared by cultivating a microorganism of the genus Elsinoe capable of producing said glucan on a nutrient medium to produce said glucan and separating and recovering said glucan.

Abstract: A glucan which is characterized by repeating units of [3)-Glc-(1.fwdarw.4)-Glc-(1.fwdarw.4)-Glc-(1.fwdarw.] wherein Glc represents alpha-D-glucopyranose residue. This glucan may be prepared by cultivating a microorganism of the genus Elsinoe capable of producing this glucan on a nutrient medium to produce this glucan and separating and recovering this glucan. This glucan may be used, for example, in the form of a film for packaging film material.

Abstract: A solar battery package having at least one solar cell substantially embedded in a block of fiber-reinforced thermosetting resin with a transparent flexible covering. The block has a portion, overlaying a light receiving area of the solar cell, which is transparent and has another portion which is either transparent or substantially opaque. A protective coating of fluorine-containing compound may be applied to the block to improve the weatherability of the solar battery package. A method of making the solar battery package is also disclosed.
