摘要:
A method and apparatus for mapping a moving direction by using sounds for people with visual impairments, in which a moving direction can be expressed multi-dimensionally by using sound information and can effectively assist people with visual impairments and the like in navigation tasks. A moving direction of a person carrying a device configured to output sounds is mapped by using a combination of sounds outputted from the device. A plurality of different sound information pieces are stored in association with three or more predetermined directions, respectively, a current position of the moving target device is identified, and then a moving direction of the device is identified. A sound obtained by combining two sounds in a ratio according to the identified moving direction is outputted on the basis of sound information pieces associated respectively with two adjacent directions sandwiching the identified moving direction among the predetermined directions.

摘要:
A pallet apparatus includes a pallet base including a caster unit and a mounting plate for mounting a product having a first fastening unit; a fixing member disposed between the product and the mounting plate of the pallet base; and a second fastening unit fixing the fixing member onto the mounting plate. The product can be fixed to or released from the fixing member by fastening or unfastening the first fastening unit. The fixing member includes a slit at a position corresponding to the first fastening unit, the slit allowing the fixing member to be inserted between or detached from the product and the mounting plate without contacting the first fastening unit.

Another third reactor or a plurality of third reactors can be provided in parallel to the third reactor, thereby producing different kinds of polybutylene phthalate with different degrees of polymerization from that produced in the main line of the third and fourth reactors or adjusting operating conditions of each of a plurality of the third reactors to increase kinds, precise quality.
摘要:
An apparatus for continuously producing polyester comprises three single reactors, i.e. a single esterification reactor (first reactor), a single initial polymerization reactor (second reactor) and a single final polymerization reactor (third reactor or final polymerizer), where at least one of the first reactor and the second reactor is free from an external stirring power source, or the third reactor is a horizontal, one-shaft-type, low speed rotation type reactor. Necessary number of reactors for the esterification and polycondensation reactions can be a minimum and necessary stirring power consumption for the reaction can be a miminum, and thus polyester polymers of good quality can be efficiently produced at a minimum energy cost in a necessary minimum reactor structure.
