    Abstract: A urinal includes: a urinal body; a high-frequency sensor which radiates a radio beam obliquely passing through an upper surface of the urinal body toward a bowl and receives a reflected wave from an object so as to generate a detection signal; and a valve which discharges or stops flushing water to the urinal body in response to the detection signal. An angle formed between a first plane including the upper surface of the urinal body and a second plane including a radiation surface of an antenna of the high-frequency sensor is in a range of more than 0 degree to less than 90 degree. A cross line where the first plane and the second plane intersect with each other is substantially parallel to a horizontal direction of the urinal body. The radio beam is a linearly-polarized wave. An excitation direction of the radio beam intersects with the cross line. An intensity of the radio beam passing through the urinal body is larger than that of the radio beam reflected by the upper surface.

    Abstract: Large-sized through holes are formed in a core layer of a printed wiring board. Large-sized vias are formed in the shape of a cylinder along the inward wall surfaces of the large-sized through holes located within a specific area. A filling material fills the inner space of the large-sized via. A small-sized through hole penetrates through the corresponding filling material along the longitudinal axis of the small-sized through hole. A small-sized via is formed in the shape of a cylinder along the inward wall surface of the small-sized through hole. The filling material and the core layer are uniformly distributed within the specific area in the in-plane direction of the core substrate. This results in suppression of uneven distribution of thermal stress in the core layer in the in-plane direction of the core layer.

    Abstract: A printed wiring board is made of first and second substrates superimposed on each other. The first and second substrates respectively include a core layer made of resin containing carbon fibers. The second substrate has the outline different from that of the first substrate. A stepped surface is defined on the front surface at least of the first substrate. Electrodes can be formed on the stepped surface as well as on the back surface of the first substrate and the front surface of the second substrate. This structure enables detection of an electric signal from the stepped surface. A further flexibility can thus be achieved in locating electrodes as compared with a conventional printed wiring board having uniform substrates simply superimposed on each other. This results in an expanded use or purpose for a printed wiring board.
