摘要:
It is an object of the present invention to provide a method for manufacturing a fused ring compound, with which a fused ring compound that has excellent charge transport property and that has excellent solubility in solvents can be obtained efficiently. The method of the present invention for manufacturing a fused ring compound involves reacting a compound expressed by the following General Formula (1a) and a compound expressed by the following General Formula (1b) in the presence of an amine and a metal complex catalyst: (where Ar11 and Ar12 are each independently an atom group constituting an aromatic ring or a heterocyclic ring; X11 and X12 are each independently a hydrogen atom or a halogen atom, and at least one is a halogen atom; and R11 and R12 are each independently a hydrogen atom, an all group, an alkoxy group, an alkylthio group, an alkylamino group, an alkoxycarbonyl group, an aryl group, a heterocyclic group, or a cyano group, provided that at least one of R11 and R12 is not a hydrogen atom).

摘要:
A casing is provided with an outer frame defining an internal space and with a partition dividing the internal space into a fan housing and a motor housing. The outer frame is formed with an inlet and an outlet allowing fluid communication between the fan housing and an exterior. The imaginary rotational axis of the fan is substantially coincident with the imaginary central axis of the inlet. The fan is positioned between the inlet and the motor. The fan includes a mount portion mounted on the drive shaft, a generally circular base plate formed integrally with the mount portion, and a plurality of vanes protruding from the base plate toward the inlet. The outer frame includes a slanted portion adjacent to the inlet and slanted in such a manner that a distance between the slanted portion and the imaginary central axis is gradually reduced in a direction toward the inlet.

A centrifugal separator comprises a driving unit, a power transmission unit including a driving shaft and a crown mounted to one end of the driving shaft, a rotor having a rotor body to which an insertion hole into which the crown is inserted is formed and including a sample holding member, the rotor being formed with a projection member so as to extend outward, a rotor casing into which the rotor is accommodated in a rotatable manner, and a receiving member disposed on the rotor casing side to receive the projection member. In a state that the crown is inserted into the insertion hole from a bottom wall side of the rotor casing, a first distance between the bottom wall of the rotor casing and a front end portion of the crown is made smaller than a second distance between a bottom portion of the projection member and a bottom portion of the insertion hole formed to the rotor body. The receiving member is formed as an annular recess having a depth larger than a difference between the second distance and the first distance.

An endoscope provided with a lighting apparatus. In this lighting apparatus, a tapered fiber is applied between a lamp and a base end face of a light guide. This taper fiber is in a tapered configuration which gradually diminishes in diameter toward an end side. The lamp is a high luminance lamp of a low outgoing angle. The lamp, a battery, and the tapered fiber of the lighting apparatus are arranged unitedly on a grip portion of the endoscope.

A pulling wire for tip articulation mechanism of endoscope is fitted with an overload preventing spring in the middle thereof. This spring is arranged to stretch upon more than a certain amount of tension. Elongation of the overload preventing spring absorbs any excessive tension which is exerted upon the pulling wire as a result of motion restriction of the endoscope. This spring is fabricated such that the material wire thereof is spirally coiled, and is simultaneously twisted so that forcing pressure is introduced in the spring in the direction in which the adjoining ring portions thereof are brought into pressure contact with one another it is subjected to tension.
