  • Patent number: 8136174
    Abstract: An object is to provide a urinal which prevents offensive odors, reduces the consumption of urinal cleaning water and prevents clogging of the urinal drain pipe line. The urinal of the present invention includes a human body sensor (7), a control unit (11), a mechanism to generate a gas with high detergency (14), a gas flow line (La) in which generated gas with high detergency flows, and a cleaning water supply line (Lw) in which cleaning water flows, and the gas flow line (La) and the cleaning water supply line (Lw) converge to mix the gas with high detergency with the cleaning water, and a cleaning fluid line (Lc) formed by confluence of the gas flow line (La) and the cleaning water supply line (Lc) is communicated with a cleaning fluid ejection hole (5) on a urinal upper edge (1a).

  • Patent number: 4995311
    Abstract: A device for making or preparing liquid coffee comprises a main body having a pair of support rails, a dripper suspended from these rails. The dripper have a filter attached thereto and an outlet formed at the bottom thereof and containing coffee powder therein. A pot is located under the dripper and have an opening which is opposed to the outlet of the dripper at a certain interval. Hot water is supplied into the dripper to make liquid coffee, which is collected in the pot, passing through the outlet of the dripper and the opening of the pot. The dripper includes a holder attached to the paired support rails, a member connected to the holder and movable up and down. The movable member is mounted on the top of the pot to enclose the space between the outlet of the dripper and the opening of the pot to thermally shield liquid coffee flowing through the space from outside air when it is at its lower positions.

  • Patent number: 4725714
    Abstract: A drip-type hot water feeder of a coffee maker incudes an electric heater for heating and boiling water fed from a water reservoir, and a timer for controlling the time for supplying an electric current to the heater to regulate the hot-water supply to a brewer. The timer has a manually movable control member for continuously variably setting the current supply time and a scale indicating the quantity of hot-water supply corresponding to the time set by the control member. Each mark of the scale has a predetermined width in the setting movement direction of the control member and includes a plurality of compensating indexes indicative of the adjustment of the control member necessary to compensate the set current supply time and thus the quantity of hot water to be supplied indicated by each mark for variations in cold water conditions influencing the time required for supplying a desired quantity of a hot water.
