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: After an end of exposure, a data level of OB signals that are imaging signals output from OB portion 400 are sampled by a CDS circuit 6 twice, to artificially generate two OB signals from each OB signal. Thereby, assuming that the total number of OB signals required to stabilize the black level in the clamp circuit 9 is n, the black level can be stabilized before it is started to output effective signals that are imaging signals from effective pixel portion 200 even if the number of OB signals output from the OB portion 400 is 1/n (in the case where pixel mixing or pixel thinning is performed, or in the case where the number of photoelectric conversion elements in the OB portion 400 is less than n). Accordingly, it is possible to prevent the image degradation by suppressing a wrong black level.

Abstract: A frequency band FC assigned to a first wireless communication system and the frequency bands F1, . . . , Fm assigned to a second wireless communication system are set up for a base station apparatus 100. The base station apparatus 100 periodically performs a frequency detection process A to detect whether or not the frequency bands F1, . . . , Fm are usable for the communication with a mobile station 201. When the base station apparatus 100 and the mobile station 201 are communicating, the base station apparatus determines whether or not the frequency band used for the communication should be changed from FC to F1, . . . , Fm in accordance with its communication status. If it is determined that the frequency band should be changed, the frequency band used for the communication is changed to the frequency band determined as usable through the frequency detection process A.
