摘要： PURPOSE:To reduce noise of an air turbine by providing a partition plate between an air turbine chamber and a brush chamber to be inclined to a floor surface, providing a main nozzle and an auxiliary nozzle at the partition plate to discharge air currents from the main nozzle upward, and rotating the air turbine and a lower part of a rotary brush in the advance direction of the suction part. CONSTITUTION:Sucked air 11 flows from a floor surface of a suction part case through a rotary brush chamber, a main nozzle 4, a runner 5, a passage 6 around the runner 5, and a receiving port 7. A jet air current 11c from the main nozzle 4 provided at an inclined partition plate between the brush chamber 1 and an air turbine chamber 2 is jetted upward to set a rotation direction 13 of the runner 5 in the advance direction 15. A rotation direction 14 of a rotary brush 3 is also set to be similar by a timing belt. In the case of a carpet or the like, when an inflow surface of a subsidiary nozzle is set to be almost half, flow at the main nozzle 4 becomes small to reduce noise. In the case of a woody floor or the like, the inflow surface of the auxiliary nozzle is fully opened to reduce noise further.

摘要： PURPOSE:To provide a better performance in terms of sucking of thread, hairs and fluff without plucking carpet wool and to prevent them from tangling around a rotary cleaning body, by forming a series of recesses in the front edge of a flexible blade, which is disposed in the periphery of the rotary cleaning body in the longitudinal direction, and in the part where the edge comes into contact with a cleaning surface. CONSTITUTION:In a blade 17 fixed to the periphery 13a of the rotary core 13 of a rotary cleaning body, the part where its front edge comes into contact with a cleaning surface has a recess 22 in the longitudinal direction. The front edge is designed so as to curve in the carpet surface, by presetting the size of the front edge of the blade 17 so that the edge is in optimum contact with the carpet surface. Because of this, thread, hairs, fluff, etc., on the carpet are picked up by means of the raised face 20 of the recess 22, to be lifted from the carpet surface and sucked. Also, the blade 17 has no projections at the front edge, therefore the carpet wool is not plucked. Further, at the instant of the separation of the blade 17 from the carpet surface, the carpet surface is excited by the reation of the curving, so that dust is lifted and sucked.

摘要： PURPOSE:To flexibly cope with the change in the connection format and rated voltage of an external electrical path without requiring a great modification in a device body and to reduce cost by using a terminal block with a different connection format at the inverter device and external electrical path sides of the terminal block. CONSTITUTION:A terminal block 140 which is in an electrical wire press- clamping format 142 at one X side and in a crimp style terminal format 141 at the other Y side is used for the connection part at a conductor bar side and that at an external electrical path side in an inverter device in a unit wall- mounted structure, thus coping with any electrical wire connection format, improving universality, and reducing cost.

摘要： PURPOSE:To reduce the fluctuation of transmission torque, and performing the lock-up, preventing the blow-up to restrict the lowering of the rotating speed by increasing a target speed change ratio at the time of lock-up, and increasing the rotating speed of a primary side pulley to reduce a difference between the rotating speed of the primary side pulley and the engine speed. CONSTITUTION:In a transmission control computer 12, a target primary side pulley rotating speed computing means 102 computes a target N1 on the basis of a diagram of speed change, which records a predetermined speed change ratio. A target speed change ratio computing means 103 computes a target speed change ratio (i) in accordance with the rotating speed N2 of a secondary side pulley on the basis of the target N1. Furthermore, a transmission control signal computing means 104 computes the speed change ratio control signal I on the basis of the target speed change ratio (i). On the other hand, a lock-up control judging means 105 judges the lock-up on the basis of the throttle open degree theta, the rotating speed N1 of the primary side pulley and the car speed V. In the case where the lock-up is judged, the final target N1 is decided in consideration of the engine speed Ne and the output of a delay time counting means 106.

摘要： PURPOSE:To eliminate the adhesion of cotton dust to a suction port brush, to lighten the suction port operation, and to prevent the wooden floor from being flawed by providing a brush in the center of a suction port, providing the suction port on the front and the rear of the brush and providing a side brush not only the left and the right of the brush but also on the front and the rear of the suction port. CONSTITUTION:A floor suction port 1 is constituted of the upper case 2 and the lower case 3, and on the outermost periphery, a bumper 4 for preventing furniture, etc., from being flawed is placed. In the lower case 3, a center brush 5 is provided in the center and in both side parts in the longitudinal direction of the center brush 5, a front side suction port 6 and a rear side suction port 7 are provided so as to be a little longer than the center brush, and the front side suction port 6 and the rear side suction port 7 join in the inside and pass through a suction passage 8, are turned, and inserted and held by the upper case 2 and the lower case 3, and connected to a suction joint 12 for communicating with a hose extension tube of the cleaner side. Cotton dust wiped off by the center brush by operating forward and backward the suction port does not adhere to the brush in the course of cleaning, the brush can be held cleanly, and also, since a hard part of the suction port constituting base material does not come into contact directly with the floor, the wooden floor is not flawed.
