Abstract: A cleaning device with a squirter for squirting liquid forward of a cleaning head is provided. The cleaning head may have a nozzle head whose squirt surface is curved. In the nozzle head, squirt directions of nozzles, which are arranged to fan out at a squirt angle, may be substantially perpendicular to tangents to the squirt surface. Therefore, liquid squirted from the nozzles may fly straight along the squirt directions without being drawn to the squirt surface.

Abstract: A cleaning implement includes a cleaning head having a cleaning operation surface on a bottom, a holding portion arranged on the side opposite the cleaning head, a pipe for coupling the cleaning head and the holding portion, and a valve opening and closing device provided to the pipe so as to be able to hold a first container for receiving a first fluid or a second container for receiving a second fluid. The holding portion includes a lever coupled to the valve opening and closing device so as to open and close a first valve of the first container or a second valve of the second container. A first ejection nozzle can eject the first fluid forward of the cleaning head, and a second ejection nozzle can eject the second fluid rearward of the cleaning head.

Abstract: A cleaning implement includes a cleaning head having on the bottom a cleaning operation surface and a valve opening and closing device that is connected to the cleaning head and can hold a first container for receiving a first fluid or a second container for receiving a second fluid. The cleaning implement further includes a first circulation path through which the first fluid is ejectable from the cleaning head and a second circulation path through which the second fluid is ejectable by interrupting the first circulation path.

The holding portion includes a lever coupled to the valve opening and closing device so as to open and close a first valve of the first container or a second valve of the second container. A spout of a second ejection nozzle for ejecting the second fluid containing an allergen inactivator is located, for example, at a height of about 30 cm or more from the floor.

Abstract: Disclosed is a pipe handle including first and second pipes which are engaged together with a male coupling of the second pipe fitted into a female coupling of the first pipe. The first pipe has a larger inside diameter in the female coupling than in a main body adjacent to the female coupling. The second pipe has a continuous outer surface without any step between the male coupling and a main body adjacent to the male coupling. The main body of the first pipe and the main body of the second pipe has an equal or almost equal outside diameter.

Abstract: Disclosed is a cleaning device with a squirter for squirting liquid forward of a cleaning head. The cleaning head has a nozzle head whose squirt surface is curved. In the nozzle head, squirt directions of nozzles, which are arranged to fan out at a squirt angle, are substantially perpendicular to tangents to the squirt surface. Therefore, liquid squirted from the nozzles tends to fly straight along the squirt directions without being drawn to the squirt surface.

Abstract: Disclosed is a cleaning device with a squirter for squirting liquid forward of a cleaning head. The cleaning head has a nozzle head with a nozzle. A liquid receiving part is provided to extend from beneath an orifice of the nozzle toward a front face of the cleaning head. Liquid dripping from the orifice of the nozzle can be led down an inclined top face of the liquid receiving part to the outside of the cleaning head, preventing the cleaning head from being soiled with a detergent, a wax or the like.

Abstract: With time intervals and transmission times of packets of real time streams, transmission end times thereof are calculated. The transmission order of packets of the real time streams is decided in the order of the earlier transmission end times thereof. Transmission end times of packets of a non-real time stream are compared with the scheduling times of packets of the plurality of real time streams. When the transmission end times of packets of the non-real time stream are earlier than any one of the scheduling times of packets of the plurality of real time streams, the packets of the non-real time streams are transmitted.

Abstract: In the event of a bus-reset, the transmission-speed-setting means sets a predetermined transmission speed and stores the predetermined transmission speed in a transmission-speed storage means. Then, the SP-extracting means receives a self-ID packet from another node by way of the bus, the physical layer and the LINK layer. The SP-extracting means extracts information on a transmission speed (SP) from the packet, and supplies the SP to the transmission-speed-setting means. The transmission-speed-setting means compares the SP with the transmission speed stored in the transmission-speed storage means to select an optimum transmission speed and, if necessary, uses the optimum transmission speed to update the stored transmission speed. The extraction of an SP, the comparison of the SP with a stored transmission speed and an operation to update the stored transmission speed if necessary are carried out every time a self-ID packet is received.
