Abstract: A locking mechanism includes a first member that is provided on one side to lock and is rotated about a rotating shaft, a second member that is provided on the other side to lock and comes into contact with the first member to rotate the first member, a rotation applying member that further applies a rotational force to the first member rotated by the second member, a restriction portion that restricts movement of the first member to be rotated in a direction in which the first member is released from a locked state, and an elastic portion that allows the first member and the restriction portion to be in elastic contact with each other and allows the first member and the restriction portion to start to be in elastic contact with each other before the first member rotated by the second member is further rotated by the rotation applying member in a release direction which is the direction in which the first member is released from the locked state.

Abstract: An apparatus includes a housing, a cover that is opened and closed on the housing, a detection part that detects opening and closing of the cover using ON and OFF, a rotating part that is rotatably supported and turns on and off the detection part, a pushing portion that comes into contact with the rotating part to rotate the rotating part in a case where the cover is closed, and a rotation applying part that applies a rotational force to the rotating part rotated by the pushing portion in a direction in which the detection part is turned on in a case where the cover is closed.

Abstract: In treating organic-containing wastewater by a biological treatment in a stage prior to a advanced treatment such as membrane separation or the like, the amount of the biological metabolites produced in the biological treatment step is reduced to reduce the amount of the organic substances flowing into the advanced treatment step in a latter stage, thereby making the advanced treatment stable and efficient and efficiently recovering treated water of high quality. Water anaerobically biologically treated in an anaerobic reaction tank 11 including an acid production tank 11A and a UASB reaction tank 11B is subjected to a coagulation treatment and then to solid-liquid separation in a No. 1 sedimentation tank 14. The resultant separated water is aerobically biologically treated water is subjected to a coagulation treatment and then to solid-liquid separation in a No. 2 sedimentation tank 24.

Abstract: A communication apparatus of the present invention has a first storing unit for storing information detected by a caller information detector, a caller identifying unit for identifying a calling place of a caller based on the information stored in the first storing unit, a second storing unit for storing information of the calling place identified by the caller identifying unit, a third storing unit for storing predetermined information, and a controller for controlling a display unit to display combined information of the calling place information stored in the second storing unit and the predetermined information stored in the third storing unit. The communication apparatus has a controller for extracting voice data selected by a voice data selecting unit and controlling the voice converting unit to output a voice signal, when the plurality of voice data correspond to the caller information detected by the caller information detector.

Abstract: A hermaphrodite housing assembly containing a plurality of positions for supporting a plurality of electrical connectors, secured captively in respective halves of the assembly for mating contacts positioned in opposite portions of the assembly.
