PROBLEM TO BE SOLVED: To provide a perpendicular feed multi-screw extruder that implements significantly improved kneading and shearing of a processing material. SOLUTION: A plurality of screws 2 having the same required length are arranged in parallel and all the screws are covered in a cylinder 9. A force feeder 1 is disposed above one end screw 2, an outlet of a strand die 10 or the like is positioned beside the other end screw 8, and a band heater 12 is circumferentially disposed on the cylinder 9. A processing material is input from above the end screw 2 and fed in a direction perpendicular to the rotary feed direction of the screws, with the cylinder 9 and screws 2 heated if necessary.

PROBLEM TO BE SOLVED: To speed up preliminary work by enabling a main implement necessary for the construction of a batter pile foundation to be transported in a lump, even if a special case is not used. SOLUTION: A second form 20 supported by a first form 10, and a guide plate 30 for the batter pile foundation are formed in sizes which enable them to be housed in the first form 10. At least the second form 20, the guide plate 30 and a form supporting implement 40 are housed in the first form 10, and an opening of the first form 10 is closed with a cover member. This enables the first form 10 to be used as a case for housing the second form 20, the guide plate 30 and the form supporting implement 40 during transportation. Since main members necessary for the construction of the one batter pile foundation are housed in the first form 10, the first form 10 can be transported in the range of the same bulk as its bulk when it is singly loaded.

PROBLEM TO BE SOLVED: To provide a guide plate and a construction method for a batter pile foundation, which can enhance batter pile driving accuracy. SOLUTION: This guide plate includes a center hole 10 for inserting a centering member, and a slit 20 for making the center hole 10 and a peripheral edge 1a communicate with each other. The centering member is relatively moved in such a manner as to be guided into the slit 20 from the lateral side of the centering member and lead to the center hole 10, so that the center hole 10 can correspond to the center of the batter pile foundation. Thus, the slit 20 for making the center hole 10 and the peripheral edge 1a communicate with each other is provided. The center hole 10 can correspond to the centering member through the slit 20 without the removal of a string, as the centering member is suspended by the string, and the batter pile driving accuracy is increased by virtue of an increase in the positional accuracy of the center of the batter pile foundation.

PROBLEM TO BE SOLVED: To improve a ventilation function in a greenhouse having a plastic film as an outer cover. SOLUTION: The apparatus for opening and closing an outer cover film has constitution that an intermediate winding shaft 12 is arranged between the base end 21a and the tip 21b of a film 21 for ceiling ventilation functioning as a ventilation member and the film 21 for the ceiling ventilation is wound from the middle part of the film. Consequently, the base end 21a of the film 21 for the ceiling ventilation constituting the ventilation member is arranged in a fixed state. While the plastic film is used as the outer cover, an excessive gap countermeasure means is not needed in comparison with a conventional greenhouse and an opening for ventilation is formed at an arbitrary part such as a ceiling part A, etc., by taking ventilation efficiency into consideration.

Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for opening and closing a ventilation film for a greenhouse, with which the drive load on the apparatus is reduced and sealability of the greenhouse is increased. SOLUTION: The apparatus for opening and closing the ventilation film for the greenhouse has a constitution that a combination of a sealing film part 11 and a netlike number 12 provided with hole parts 12d for ventilation is used as the ventilation film 10 for the greenhouse and the ventilation film is wound on winding shafts 21 and 22 in the adjacent direction of the sealing film part 11 and the netlike member 12. Consequently, since the whole hole parts 12d for ventilation formed on the netlike member 12 is closed by unwinding the whole netlike member 12, installation of a canopy-like platy member between the winding shaft and a stationary beam is not required. The driving load of the winding shaft is more reduced than that of a conventional apparatus. Since the installation of the canopy-like platy member is not required, an opening part 110 for ventilation is surely sealed even if the framework materials of the greenhouse cause meander shapes.

PROBLEM TO BE SOLVED: To provide a driving apparatus for a greenhouse saving labor in driving a member which is the object of operation in the greenhouse. SOLUTION: The driving apparatus for the greenhouse comprises an actuator 10 provided with a cylinder 11 filled with a driving material changing the volume corresponding to temperature and a piston 12 sliding in the cylinder 11. The piston 12 is connected to a thermally driven arm 32 connected to the member which is the object of the operation and the cylinder 11 is fixed and arranged in a supporting frame 20. When the temperature is increased, the driving material is expanded to push out and elongate the piston 12. Thereby, the thermally driven arm 32 is rotated. A connecting arm 40 is rotated through an actuating arm 33 and a rotating shaft 31 by rotating the thermally driven arm 32. Thereby, the member which is the object of the operation is operated. The actuating arm 33 can manually be operated irrespective of the elongated state of the piston 12 by releasing the engaged state of the thermally driven arm 32 with the actuating arm 33.

PROBLEM TO BE SOLVED: To wind or unwind a plurality of kinds of films having different functions with a simple structure, and to pull the films with a tension on some level without tightening by a mica wire. SOLUTION: There is provided a movable winding shaft 20 which is movable accompanied by the winding or unwinding operation of the films 210 and 220 with adjacent portions of a first film 210 and a second film 220 wound together therearound. A base end portion of the second film 220 is pivotably supported by a bearing member 30a, and supported by a fixed winding shaft 30 which is not moved by the winding or unwinding operation of the films 210 and 220. The tension in each film can be increased by winding the second film 220 by a predetermined quantity by the fixed winding shaft 30 in an arbitrary state irrespective of each winding quantity of the first film 210 and the second film 220.
