IPC: G05D22/00
Filed: 1984-09-29
Abstract: PURPOSE:To prevent an excessive humidification of a plant, and to protect it exactly from dryness by leading in a water feed mode and an additional water feed mode. CONSTITUTION:A dry and wet detecting sensor 7 for detecting a dry or wet state of soil in a flower pot 5 is installed at a suitable part of the pot concerned. A controlling circuit 9 detects a fact that the soil in the pot has dried and the dry and wet detecting sensor 7 is turned off, and opens the valve by energizing a solenoid 6d of a solenoid opening and closing valve 6. As a result, water flows to the downstream part of a control pipe from the solenoid opening and closing valve 6, and water is fed to the flower pot 5. When the dry and wet detecting sensor 7 is wetted by feed water, and goes to an on-state, the device enters into an additional water feed mode after that time point, and a timer 18 is operated. When the timer 18 is turned off after the time set in advance has elapsed, the controlling circuit 9 stops an electric conduction to a relay R, opens a contact Sr, opens the solenoid opening and closing valve 6, and stops the feed water to the flower pot.

IPC: B65H5/06
Filed: 1981-12-16
Abstract: PURPOSE:To enable a paper feed with no snaking motion without increasing the number of rolls while leaving the roll surface smooth by applying a pinch force so that hard rolls with a narrow width sink deep into a long and slender roll by the thickness of the paper and more. CONSTITUTION:By making hard rolls 1 sink into an elastic roll 2 by the thickness of the paper S or more, the smooth elastic roll can obtain a friction force equal to or more than that of a roll applied with a pattern or a hallmark, and besides, the change of the friction force is small as compared with a roll having a pattern or a hallmark. In addition, to maintain the friction force of the elastic roll 2 constant, the axial direction length W of the hard roll 1 is selected to be twice the diameter D of the elastic roll 2 or less. Accordingly, the friction force of the elastic roll 2 is maintained high and constant and the paper S can be fed with no snaking motion under a constant friction force by limiting the pinch width of the paper S by means of the hard rolls 1.
