  • Patent number: 6299277
    Abstract: An ink jet printer measures a time period over which a print head thereof is in intimate contact with a head cap thereof, and based on results of the measurement regularly removes thickened ink adhering to the print head. An ink jet printer according to another form measures a time period over which the print head is in a state in which ink is neither delivered therefrom nor drawn therein, and a parameter related to an evaporation rate of a solvent or water from the ink. The ink jet printer removes thickened ink adhering to the print head based on the measured time period and the measured parameter.

  • Patent number: 6247339
    Abstract: A washing basket doubling as a spin-drier is disposed rotatably in a water-tub. A motor drives the basket, which generates centrifugal force. The centrifugal force cause cleansing water to run through the fibers of clothes in the basket, thereby cleansing the clothes. A control device cause variation of the spinning of the basket so that the centrifugal force working on the clothes is varied, which cleanses the clothes more effectively. The clothes in the basket receive only water-moving-force, and they can be cleansed without being damage or entangled.
