A waste-material entry prevention member arranged upstream of a flow sensor is a rod- or plate-like member protruding halfway across the cross-section of a flow passage. Hence, vortexes or energy of the vortexes produced in fluid flowing by the waste-material entry prevention member is diffused by a stream of the fluid passing through a space left between the waste-material entry prevention member and the wall surface of the flow passage which the waste-material entry prevention member faces. Thus, production of vortexes is held down. Further, by making the flow sensor generate heat or heating the flow sensor, thermophoresis of the fluid is caused near the surface of the flow sensor. By this, particles contained in the fluid are prevented from accumulating on the flow sensor.

A portable and sealable waste disposal receptacle receives human waste material through an opening in an outer chamber. The waste passes through an inner chamber, which is suspended within the outer chamber, and passes through a one-way valve located at the bottom of the inner chamber into a lower chamber portion of the outer chamber. The one-way valve is fashioned from the bottom edges of the inner chamber, where a biasing strip is mounted in compression along one of the bottom edges, which causes the bottom edges of the inner chamber to be biased closed in sealing contact except when waste enters the inner chamber, the weight of which is sufficient to overcome the closing bias of the biasing strip, allowing the waste to flow into the lower chamber. Once the waste has cleared the inner chamber, the biasing member causes the bottom edges to come together in sealing contact, preventing the flow of waste back through the inner chamber.

The invention relates to an installation method for the wall constructed by honeycomb veneers. When in construction, the honeycomb wall is designed in a way that the honeycomb veneers at two sides arestaggerly spliced so as to combine into a whole. Compared with the prior integral wallboard, the walls are connected with no need of a keel, and only honeycomb veneers are staggered and spliced; without the keel, the internal layers of the walls completely take the honeycomb paper as the sandwich core, and the sound insulation and thermal insulation effects are better because the keel is no longer utilized for partition.
