  • Patent number: 9009877
    Abstract: Air suction device for a flush toilet configured to suction air from a toilet drain duct having a suction chamber dividing a tank body interior, a float in the suction chamber and an on-off valve closing an air inlet when the float lifts to prevent air flow from the toilet drain duct side into the suction chamber. The air inlet is higher than the water level in a toilet flushing standby mode. The on-off valve opens the air inlet to allow air flow form the drain duct side in the suction chamber when flush water in the tank drops such that the float is lowered form the raised position. An embodiment includes a valve chest, a float and attracting member for on-off valve manipulation. Another embodiment includes a valve chest with a small air flow manipulation hole.

  • Patent number: 8536088
    Abstract: In an image-forming method, a ribbon-shaped thermal transfer sheet with a dye layer and a protective material layer arranged side-by-side in the longitudinal direction is moved, and thermal energy is applied from a thermal head while arranging a recording medium to face the dye layer to thermally transfer the dye layer onto the recording medium to form an image. Thermal energy is applied while arranging the image to face the protective material layer to thereby form a protective layer on the image by thermal transfer. A ribbon-shaped surface-property-modifying sheet including a surface-property-modifying region for modifying the surface of the protective layer is moved, and the protective layer is aligned with the surface-property-modifying region of the surface-property-modifying sheet. Heat and pressure are applied from the thermal head and the surface-property-modifying sheet is detached after cooling to modify the surface condition of the protective layer.
