Abstract: A nanofiber manufacturing apparatus (100) which produces nanofibers (301) by electrically stretching a solution (300) in space. The apparatus includes: an effusing body (115) having effusing holes (118) for effusing the solution into the space, a tip part (116) in which openings (119) are arranged at given intervals, and two side wall parts (117) provided so as to extend from both sides of the tip part so that the effusing holes are located between the side wall parts and the distance between the side wall parts increases with the distance from the tip part; a charging electrode (121) disposed at a given distance from the effusing body; and a charging power supply (122) which applies a given voltage between the effusing body and the charging electrode.

Abstract: A splittable conjugate fiber that even in the polishing of precision equipments, such as a hard disc, is free from injuring of polishing object parts and allows precision polishing. The splittable conjugate fiber is one composed of, containing substantially none of titanium dioxide, a polyester component and a polyamide component, characterized in that the cyclic trimer content of the polyester component is less than 1.0%. Preferably, this product is produced under conditions such that the difference between polyester-containing cyclic trimer after melt extrusion and cyclic trimer of polyester pellet as a raw material is less than 0.3%.

Abstract: An apparatus is provided for supporting the development of a sequence software to be used for controlling the operation of an automated equipment. A sequencer specification input device inputs specification information of various types of sequencers. Equipment characteristics of an equipment to be controlled are implemented by inputting simulated characteristic thereof. An arbitrary environment of the operation of the equipment is implemented by inputting a simulation condition. The result of the executed operation of the equipment can be checked in an arbitrary form.

Abstract: In a data transfer apparatus, as one substation in a loop type signal transfer system, e.g. for use in an automatic machine, synchronization information and address information are received and the address is checked by an address coincidence circuit; when address coincidence is detected the data information in the received signal is replaced by serialized data which is contrived by parallel-serial conversion of the parallel input data at the substation; therefore there is no need of once storing the entire received signal transferred, and therefore, high speed data transfer results.
