CONSTITUTION:An arm 2a is shifted toward a bath tub body 1 while steppingly applying a foot pressure to a first pedal 2. As the locking of the arm 2a is released from a lock point 18a, a bed 24 is lowered by its own weight in the bath tub body 1 while the arm 2a is lifted up to be locked at an upper lock point 18b. At this time, the sudden lowering of the bed 24 is prevented due to a buffer 20 and the load of a helper's foot applied to the first pedal 2. Then, by releasing the foot, as the arm 2a is released while retaining by hand from the lock point 18b, the bed 24 is further lowered sinking to a deeper position. At this time, a rod 14 is retained by a supporting rod 7 causing a pedal 4 to be automatically lifted up. The bed 24 is bent at a hinge 26 portion and the side on which a pillow 25 is provided is supported by the inner wall of the bath tub body 1 to be utilized as a back.

Abstract: PURPOSE:To uniformize the take-out amount of an adsorbent, by providing a quantitative valve for constantly controlling the flow amount at the time of the downward passage of water in the raw water guide passage provided so as to be communicated with an inflow space. CONSTITUTION:A pump 18 is driven to pass raw water through an absorbing tower 11 as an upward stream from a raw water tank 19 through a line L1. The substance to be removed in raw water is adsorbed by activated carbon 12 while the treated raw water is taken out through a line L0. The taking-out of activated carbon lowered in its adsorbing capacity is performed by stopping the driving of a pump 18 and operating a constant flow valve 25 and opening a drain valve 20. A drain downward flow amount is made constant by the constant flow valve 25 so as to uniformly pass waste carbon through a support plate 14 from the adsorbing tower 11. In this state, the drain valve 20 is opened until a desired amount of waste carbon passes through the support plate 14 to be fallen in the inverted triangular conical part 13 of the adsrobing tower and, after the waste carbon was accumulated, the drain valve 20 is closed to store the waste carbon in a waste carbon tank 21.

Abstract: PURPOSE:To obtain a device which simplifies mechanism by providing a means for taking up a web in accordance with the amt. of the conveyed cleaning web. CONSTITUTION:A heat-resistant web 1 impregnated with silicone oil is pressurized between a fixing roller 3 and a sponge roller 2 and is taken up on a shaft 7 while the toner remaining on the circumferential surface of the roller 3 is scraped off. The web 1 is conveyed as a gear 16 fixed to the shaft 2a of the roller 2 is driven by a gear 15 on an output shaft 10a of a motor 10 to rotate the roller 2. The force to convey the web 1 in this case is the friction force between the roller 2 and the web 1. This friction force is fairly larger than the resistance force between the web 1 and the roller 3 as the winding angle of the web 1 to the roller 2 is large owing to a large coefft. of friction between the roller 2 and the web 1 and therefore the web 1 is conveyed smoothly.

Abstract: PURPOSE:To improve the flow of ink and to equalize the thickness of the ink supplied to the surface of a printing cylinder by dextrously arranging two swing rollers and six mill rollers between the first swing roller and the second swing roller. CONSTITUTION:Ink in an ink bottle 21 is adhered by the rotation of a bottle roller 22 onto the peripheral surface, and is transferred intermittently to the first swing roller 23 via a transfer roller 25 which reciprocates upon scraping of a roller arm 24.
