  • Patent number: 8900702
    Abstract: An artificial hair and a wig using the same are provided which have the property of thermal deformation expanding upon heating by a hair drier or others used for hair styling. The artificial hair 1 is made by mixing at the pre-determined ratio a semi-aromatic polyamide having a glass transition temperature between 60-120° C. and a resin not expanding in said temperature range. The artificial hair may have a sheath/core structure comprising a core portion 5B and a sheath portion covering the core portion. As the resin not expanding in said temperature range, polyethylene terephthalate or others can be used, and as the sheath, nylon 6 or nylon 66 can be used. Said artificial hair 1 can maintain its shape at room temperature or after shampooing due to thermal deformation by heating in steam atmosphere at temperature of glass transition or higher or about 80-100° C.

  • Patent number: 6062670
    Abstract: The present invention relates to a discharge recovery processing of an ink jet recording apparatus which forms an image on the recording medium by discharging the ink. The invention aims to prevent the increase in the running costs and the shortened life of a waste ink tank by preventing the wasteful ink consumption which may be caused by the dual use of an automatic recovery processing and a manual recovery processing after the replacement of an ink tank.Also, the invention further aims to provide an ink jet recording apparatus with high safety and reliability as well as effecting an appropriate recovery by controlling the movement of head in involving the recovery.

  • Patent number: 5997120
    Abstract: In a recording apparatus using a plurality of kinds of head cartridges each comprising an ink jet recording head and an ink tank formed as a unit, the present invention prevents, when a wrong head cartridge has been mounted during cartridge exchange, data regarding the remain of ink in a thitherto used cartridge of other kind from being lost, and enables the remain of ink in that cartridge to be confirmed. A user is pressed for the exchange of the head cartridge now mounted to thereby effect the exchange actually, and is called on to confirm whether the newly mounted head cartridge is a right one, and the initialization of the data regarding the remain of ink is effected when the user has done the inputting of the confirmation.
