Abstract: A toilet assembly having an automatic ventilation system which includes a high-powered suction member, an innovative motion sensor, a siphonic action member, and discharging member for objectional odor. While the user sits on the toilet seat ring, the objectional odor is effectively ventilated. When the user stands up and pushes a flush push button, the toilet assembly is effectively flushed.

Abstract: An adjustable belt fastener comprising a male fastener member adapted to be attached to one end portion of a belt, the male fastener member including a spring biased operating plate provided with a tongue member, and a female fastener member adapted to be attached to the other end portion of the belt, the female fastener member including a plurality of slots for selectively receiving the tongue member of the operating plate.

Abstract: A data output buffer, which includes a data output driver which in turn includes a pull-up circuit (14) operating in response to a first signal and a pull-down circuit (I10) operating in response to a second signal, and a control circuit for sensing a current flowing into the pull-down circuit via a feed-back and controlling the slope of the second signal in accordance with the sensed current. The control circuit includes a sensing circuit (I13) for sensing current flowing into the pull-down circuit upon driving data, and the magnitude of noises generated at the actual ground line (GND.sub.1 +GND.sub.2) due to the current, a voltage adjustment circuit (I14) which operates in response to the output signal of the sensing circuit and thereby adjusts the gate voltage of the pull-down circuit. Thereby, the noises generated in the chip are repressed without affecting the operational speed of the chip.

Abstract: A toilet assembly for use in recreation vehicles, which comprises an air tube member, a flapper valve, and an on/off switch whereby while the user sits on the toilet seat ring, the objectionable odor is effectively ventilated and when the user stands up, the objectionable odor does not flow backward.

Abstract: A toilet assembly having a combined automatic ventilation and flushing system, which comprises a returnable solenoid member, a trap way, a trap way valve member, a multifunctional tube member, and a motion sensor whereby while the user sits on the toilet seat ring, the objectionable odor is effectively ventilated and when the user stands up, the toilet assembly is automatically flushed.

Abstract: A non-siphon type ventilating toilet assembly includes an U-shaped ventilation tube disposed in the toilet holding tank for ventilating objectionable odor from the toilet bowl, the ventilation tube containing a cap valve which moves upwardly and downwardly along an outer-screwing shaft of an upper motor and a fan of a side motor, and both motors connected to a motion sensor, whereby upon opening the toilet seat cover having a sensor aperture, while the user sits on the seat ring, the motion sensor actuates for allowing both motors to be operated and simultaneously the cap valve is in an open position and the objectionable odor is ventilated, and in turn when the user stands up and flushes the toilet assembly, the motion sensor deactivates for allowing both motors to be stopped and simultaneously the cap valve is in a closed position and the flush water discharges the waste products to the sewer discharge line.

Abstract: A toilet assembly which includes a toilet stool having a ventilation conduit disposed adjacent to the back wall portion of the toilet stool for ventilating objectionable odor from a toilet bowl, the ventilation conduit extending annularly around a siphon conduit at the point where they communicate with a sewer discharge line, a fan member disposed in the lower portion of the the ventilation conduit, a toilet holding tank having a motion sensor disposed on the front exterior of the toilet holding tank and free of interference from the opening and closing of a toilet seat cover, a gas exhaust duct connected to the ventilation conduit and having a raised portion disposed at the interior surface thereof for allowing exhaust gas to flow from a flush ring to the ventilation conduit and preventing the flush water from flowing into the ventilation conduit, whereby opening the toilet seat cover while the user sits on the seat ring, the motion sensor actuates the fan member allowing the objectionable odor to be ventila
