Abstract: In a drum type washing machine, a drum 23 is mounted to rotate about a horizontal axis extending in the lateral direction in a tub 20. A tub opening 20b with a tub door 20a is formed in the tub 20 under the throw-in opening 3 formed in the front part of the top of the housing. A drum opening 23a with a drum door composed of a double door opening frontward and backward is formed in the peripheral wall of the drum 23. The drum 23 is stopped so that the drum opening 23b coincides with the tub opening 20b. The drum door 23a, forced into its opening direction, is held in a closed position by an engagement of a claw 43 and an engagement hole 53. When a user rotates a operation lever 63b for latching or unlatching the tub door 20, the drum door open/close mechanism 65 functions to make two rods 65a and 65b project or withdraw, whereby the drum door 23a is brought into an engaged or unengaged state. By this mechanism, the drum door 23a opens or closes with the opening or closing operation of the tub door 20a.

Abstract: In accordance with the present invention, there is provided a water treatment system for sterilizing water retained in a water container, the system comprising: a circulation process line for pumping the to-be-sterilized water out of the water container, sterilizing the water through electrolysis, and feeding the sterilized water back into the water container; means for producing a sterilizing solution having a sterilizing function by electrolyzing an electrolytic solution containing chlorine ions and having a function of promoting an electrochemical reaction; and means for supplying the produced sterilizing solution into the circulation process line as required.

Abstract: The present invention is directed to a new water treatment device comprising an electrolytic tank to put water in, an electrode provided in the electrolytic tank, a water treating path for pouring, from a pool storing water, the water into the electrolytic tank and returning to the pool the water in the electrolytic tank, a residual chlorine sensor for measuring the residual chlorine concentration of the water, and a circulating pump provided on the downstream side of the electrolytic tank on the water treating path in order to circulate the water, and capable of simply and efficiently sterilizing water stored in pools of various sizes from a swimming pool to a home bathtub.

Abstract: A clothes drier according to the present invention can minimize failures in a sensor and can satisfactorily detect drying processing irrespective of the environment. In the clothes drier, an atmospheric temperature sensor 44L for detecting the substrate temperature required to determine the termination of the drying processing is disposed outside a circulating duct 18 and is mounted on a control substrate 42 having a thermal capacity on which a microcomputer for controlling operations performed by the clothes drier is mounted. Since the sensor 44L is provided outside the circulating duct 18, the sensor 44L is less affected by dust and water, as compared with a case where it is provided inside the circulating duct 18.

Abstract: In a turret type yarn winder, a contact pressure acting on a roller bail by a yarn package is detected and used for controlling the rotation of a turret disc in accordance with the development of yarn layers on a bobbin so that the contact pressure is maintained at a predetermined value. A roller bail (5) detects a pressure acting thereon from a yarn package by a contact pressure sensor (7). If the detected contact pressure is higher than a target value, the turret disc (1) is driven in the direction to reduce the contact pressure. A driving torque of a motor (11) for driving the turret disc (1) is controlled in the normal/reverse direction by a signal corresponding to a deviation between the detected contact pressure and the target value so that the detected contact pressure coincides with the target value.

Abstract: A clothes dryer comprising a body having a drying chamber defined for accommodating clothes; a heater provided in the body; a heated air path for supplying dried air heated by the heater to the drying chamber to dry the clothes placed in the drying chamber; a door for closing and opening the drying chamber; a porous member impregnated with an agent; a supporting member provided on the door, detachably holding the porous member and provided with an aperture for supplying the agent held by the porous member into the drying chamber.

Abstract: A clothes dryer having a body with heater therein and a rotatable drying chamber is provided with a dual side rotating bladed heat exchange type fan having in its outer portion a group of grooves; and a partition member having an opening whose inner surface is opposed to the outer surface of said dual side bladed fan for separating paths of heated air and cooling air together with said dual side bladed fan in said body; the partition member has a group of fixed grooves interleaved with the fan rotating grooves to form a labyrinth seal; the fixed grooves extend from a base or the partition member and have a rising portion extending in the heated air path to inhibit the leakage of heated air from the heated air path to the cooling air path and have an opening to provide communication between the heated air and the cooling air.
