  • Patent number: 9213140
    Abstract: The fiber component of the present invention has a fusion splice section for connecting optical fibers. The optical fiber as the receiver of transmitted light is coated with at least two-layer resin. In the vicinity of the fusion splice section for connecting optical fibers, the innermost layer of a resin-coat section is uncovered with other resin coat at the boundary between the resin-coat section and resin-coat removed section of the optical fiber coated with two-layer resin. The structure effectively releases light and suppresses increase in temperature of the resin-coat section, protecting the optical fibers from burn-out.

  • Patent number: 9057374
    Abstract: An oilless screw compressor incorporating water-cooled cooling units for cooling compressed air discharged from compressor bodies having a pair of male and female screw rotors which can be rotated in a contactless and oilless manner, the cooling units comprising a plate type heat-exchanger, and the amount of cooling water for the plate type heat-exchanger being adjustable. With this configuration, a difference between a temperature during load operation and a temperature upon automatic stopping and during unload operation of the compressor can be reduced, so that the cooling unit can be restrained from being damaged or broken within a short period, thereby it is possible to provide a highly reliable oilless screw compressor.

  • Publication number: 20140249814
    Abstract: An object recognition system is applicable to practical use, and utilizes image information besides speech information to improve recognition accuracy. The object recognition system comprises a speech recognition unit to determine candidates for a result of speech recognition on input speech and their likelihoods, and an image model generation unit to generate image models of a predetermined number of the candidates having the highest likelihoods. The system further comprises an image likelihood calculation unit to calculate image likelihoods of input images based on the image models, and an object recognition unit to perform object recognition using the image likelihoods. At the time of generating the image model of the candidate, the image model generation unit first searches an image model database, and, when the image model of the candidate is not found in the database, the image model generation unit generates said image model from image information on the web.

  • Patent number: 8791384
    Abstract: Disclosed is a method for hybrid welding in which a laser beam is applied to the welding position of objects to be welded, and at the same time, a first wire is fed to the welding position so as to perform arc welding using an arc generated between the objects to be welded and the first wire. In this method, one or more second wires are fed to a molten weld pool formed by the laser beam and arc welding, thereby increasing the amount of welding without increasing the arc current.
