PROBLEM TO BE SOLVED: To prevent the malfunction of a ventilation member and to enable a proper ventilation corresponding to a temperature in a greenhouse. SOLUTION: This ventilation control mechanism for a greenhouse has a constitution that a temperature sensor 10 and a temperature control part 20 are both retained in a supporter 30 to be arranged adjacent to cultivated plants. Consequently, the influence of external noise is reduced, the malfunction of the ventilation member is prevented and a proper ventilation corresponding to a temperature in a greenhouse can be actualized.
Abstract:
PROBLEM TO BE SOLVED: To provide a wire rope that is excellent in bending fatigue durability even under the condition such as a high load, a long distance, or a long stroke, and suppresses the deformation, the pop-out of a core wire, or the like. SOLUTION: The wire rope includes a core wire and side wires twisted around the core wire. The core wire has an outer diameter 0.8 or more times that of the side wire and the wire rope has a tightening ratio of not less than 15% and not more than 120% as calculated from the following formula: the tightening ratio={1-(b-2×c)/a}×100 wherein (a) denotes an outer diameter of the core wire; b denotes a shaping length of the side wire; and c denotes an outer diameter of the side wire.

Abstract:
PROBLEM TO BE SOLVED: To lower the level of transmission loss of the rotation power from the inlet shaft side than the conventional one. SOLUTION: The side edge faces 43a, 43b of the acting piece 43 on the inlet side of the input shaft 40 arranged so that it may be positioned between the inside faces of individual hook parts 31, 32 formed by the coil spring in the casing, are formed so that they may press the inner sites than the bent sites in the hooks 31, 32. In addition, outward projecting collars 56, 57 are provided to the acting piece on the outlet side of the output shaft 50 whereby the contact positions of the coil spring 30 to the hooked parts 31, 32 become almost same, the deformation of the hooked parts 31, 32 can be inhibited and the transmission loss can be reduced.
Abstract:
PROBLEM TO BE SOLVED: To provide a cultivation apparatus intended for performing vertical movement by a simple mechanism with a comb-like rod. SOLUTION: The cultivation apparatus is such that a first vertical transport mechanism 40A transports all cultivation beds 10A put on one cultivation bed putting mechanism 20A, and cultivation beds 10A put on a second horizontal transport mechanism 30B and located on the other end of the one cultivation bed putting mechanism 20A, until the cultivations beds 10A put on the one end of the one cultivation bed putting mechanism 20A are put on a first horizontal transport mechanism 30A. Furthermore, a second vertical transport mechanism 40B transports all cultivation beds 10B put on the other cultivation bed putting mechanism 20B, and cultivation beds 10B put on the first horizontal transport mechanism 30A and located on one end of the other cultivation bed putting mechanism 20B, until the cultivations beds 10B put on the other end of the other cultivation bed putting mechanism 20B are put on the second horizontal transport mechanism 30B.

Abstract:
PROBLEM TO BE SOLVED: To provide a stretch device for an exterior covering film for a greenhouse enabling securely and easily stretching the exterior covering film to be set in an openable and closable manner so as to be imparted with a desired tension without damage, and to provide a stretch method for the exterior covering film for the greenhouse using the stretch device. SOLUTION: The stretch method comprises connecting the base edge of a first belt member 11 to a rolling pipe 40 fixed with the edge of the exterior covering film 30 and setting a loop part 11c as a part to-be-engaged on a free edge. The hook member 12d of a second belt member 12 constituting a tension-imparting member is engaged with the loop part 11c so as to adjust the length of the second belt member 12. As a result, the exterior covering film 30 can be securely and easily stretched without damage. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a pulley member for a greenhouse lightening pulley exchange work easier and reducing working time. SOLUTION: The pulley member for a greenhouse is structured so that attaching plates 32c, 32d are connected to a pair of bearing plates 32a, 32b faced each other while interposing the pulley between them to be superimposed to each other, and are attached to pipe members to be fixed. A pair of the superimposed and fixed attaching plates 32c, 32d are separated from each other when disconnected from the pipe members so as to detach a driving wire hung around the pulley through the space between both of the attaching plates. In the pulley exchange work, the attaching plates 32c, 32d are detached from the clamping plates of a greenhouse pulley unit and the pipe members, and thereby only the pulley members for being arranged for the greenhouse can be detached through the space between the pair of the attaching plates 32c, 32d while the driving wire is kept stretched.

Abstract:
PROBLEM TO BE SOLVED: To provide a curtain guiding mechanism of a curtain opening closing device for a greenhouse capable of easily performing connecting work. SOLUTION: A connecting member 5 connecting a guiding pipe to a traveling wire has a first connecting body 51 and a second connecting body 52. The first connecting body 51 is attached to the guiding pipe after inserting the traveling wire into incisions 51d and 51e. The second connecting body 52 has a folded part 52b. The vicinity of the folded end presses the outer surface of the guiding pipe when engaging hole parts 52c and 52d with the engaging parts 51j and 51k of the first connecting body 51 followed by laying to be almost parallel with the guiding pipe.
