    摘要： In a device for coupling optically a light source with an optical transmission path, the present invention interposes an optical transmission path structure at the center of the distance between them in order to improve the optical coupling efficiency. The optical transmission path structure consists of a plurality of light transmitting elements arranged so that the light from the light source is received by the structure as incident light and is sent out therefrom as outgoing light at an outgoing angle which is equal to the angle of incidence. The light transmitting elements are arranged in parallel with the optical path of the light emitted from the light source and according to this arrangement, the system of the present device becomes equivalent to a system in which the positions of the light source are located at points of .+-.l.sub.1 from the light outgoing surface of the optical transmission path structure. When used with an optical fiber, the optical transmission path structure is disposed such that the distance from the light source to one end face of the optical transmission path structure is the same as the distance from the end face of the means for transmitting to the other end face of the optical transmission path structure.

    摘要： Novel highly pure and stable crystals of .beta.-nicotinamide-adenine-dinucleotide tetrahydrate (NAD) which is triclinic system and has a space group of P1 or P1 and lattice constants: a=8.861 .ANG., b=11.181 .ANG., c=8.630 .ANG., .alpha.=90.82.degree., .beta.=103.40.degree. and .gamma.=109.71.degree.. The crystalline NAD is prepared by cooling a 20 to 60 w/v % aqueous solution of amorphous NAD, which has preferably been treated with a porous weakly basic anion exchange resin to remove impurities, at a temperature of 0.degree. to 20.degree. C. When the crystalline NAD is added to the aqueous solution as seeds, the desired high pure crystalline NAD is prepared without conducting the treatment of amorphous NAD with the porous weakly basic anion exchange resin. A high pure amorphous NAD is obtained from the crystalline NAD by dissolving the crystalline NAD in water and subjecting the aqueous solution to freeze drying or precipitation with a solvent.

The magnet is a non-ferromagnetic phase that is intercalated between a hard magnetic phase with a rare-earth magnet composition and a soft magnetic phase, wherein the non-ferromagnetic phase reacts with neither the hard nor soft magnetic phase. A hard magnetic phase contains Nd2Fe14B, a soft magnetic phase contains Fe or Fe2Co, and a non-ferromagnetic phase contains Ta. The thickness of the non-ferromagnetic phase containing Ta is 5 nm or less, and the thickness of the soft magnetic phase containing Fe or Fe2Co is 20 nm or less. Nd, or Pr, or an alloy of Nd and any one of Cu, Ag, Al, Ga, and Pr, or an alloy of Pr and any one of Cu, Ag, Al, and Ga is diffused into a grain boundary phase of the hard magnetic phase of Nd2Fe14B.

    摘要： A method of static reactive power compensation is disclosed wherein the system voltage is compensated by supplying advanced-phase or retarded phase reactive power in dependence upon the difference between the system voltage and a reference voltage. The difference is formed by a comparator which receives a variable reference voltage from a filter containing a time lag circuit and which receives the system voltage as an input. For transients, the output of the filter does not change and thus reactive power is applied. For smooth variations, the output of the filter follows that of the system voltage so that the output of the power compensation circuit is maintained at zero.
