A system for transplant production comprising: at least one air conditioner installed in a completely light shielding closed structure surrounded by a thermally insulated wall, the air conditioner controlling the temperature and humidity of air in the closed structure; at least one box-shaped culturing module disposed in the internal space of the closed structure, the culturing module having a front face opening which is opened to the internal space of the closed structure; a plurality of transplant production shelves arranged vertically in multi-layer in the culturing module to form a transplant production space between the upper and lower transplant production shelves; a plurality of plug trays for holding a plant growing medium mounted on each transplant production shelf; a sub-irrigation unit capable of irrigation from the bottom of the plug trays mounted on each transplant production shelf; an artificial lighting unit provided on the back of each transplant production shelf, the artificial lighting unit irradiating light to the lower plug trays; and at least one air fan fixed to the back wall of each transplant production shelf of the culturing module. By sucking the air whose temperature and humidity have been controlled by the air conditioner using the air fan from the front face opening of the culturing module and sending the air to the rear of the back wall of each transplant production shelf, temperature-controlled and humidity-controlled air can be effectively generated.
摘要:
An information processing apparatus that can adjust the scrolling speed for data displayed in an application window on a display and display a visual scrolling speed indicator. When the user manipulates a mouse to request scrolling of data in a window, the display form of the mouse cursor is changed. That is, in addition to the mouse cursor, one or more speed indicators appears in the scrolling direction. The number of speed indicators which are displayed corresponds to the scrolling speed. The speed indicators are arranged from the center of the mouse cursor in the scrolling direction. A speed indicator is shaped like a small isosceles triangle, and as its vertex is facing in the scrolling direction, it is a very effective visual aid for a user. Preferably, one speed indicator is displayed for a low scrolling speed, two for a moderate scrolling speed and three for a high speed scrolling. Since the speed indicators are extended in the scrolling direction in accordance with the current scrolling speed, a user can intuitively and quantitatively comprehend the scrolling speed and direction. Since the speed indicator is displayed in the vicinity of the mouse cursor, a user does not need to remove his or her eyes from a focus point on the display screen and the continuity of the operation can be maintained.

A flexible pipe coupling is disclosed. This coupling comprises a large diameter cylindrical hollow body, a pair of small diameter cylindrical hollow bodies each having one end portion disposed inside each end of the large diameter cylindrical hollow body on the same axial line, and an elastic sleeve member for connecting each end of the large diameter cylindrical hollow body to one end of each of the small diameter cylindrical hollow bodies. The elastic sleeve member is provided at its both ends adjacent to the cylindrical hollow bodies with protrusions each extending outwardly in the widthwise direction of the sleeve member at a radius of curvature corresponding to 0.1.about.0.4 times the thickness of the sleeve member, whereby the durability of the coupling is further improved.
摘要:
An apparatus for producing seedlings, wherein rootstocks and scions are nursed on multi-staged seedling culture shelves installed in a closed-type structure surrounded by light-interceptive walls, and wherein the rootstocks and scions are joined to each other to produce grafted seedlings. The grafted seedlings are placed on shelf boards of the seedling culture shelves and covered with a light-transmitting shield including vent holes, and light is projected onto the grafted seedlings through the light-transmitting shield to weld the seedlings. The relative humidity in the light-transmitting shield immediately after the grafting is raised by the evaporation of moisture from the rootstocks and the scions. When photosynthesis is stimulated, gas exchange between the carbon dioxide gas-containing atmosphere within the closed type structure and the atmosphere within the light-transmitting shield are accomplished to replenish an inner space of the light-transmitting shield with carbon dioxide gas.

摘要:
It is intended to provide an apparatus for producing seedlings and a method therefor whereby, in producing grafted seedlings of fruit vegetables, a process from the culture of their stocks (rootstocks and scions) to welding after the grafting can be accomplished in a consistent process at low cost. Rootstocks and scions are nursed on multi-staged seedling culture shelves 3 installed in a closed-type structure surrounded by light-interceptive thermally insulating walls, and then these rootstocks and scions are joined to each other to produce grafted seedlings 8. Then, these grafted seedlings 8 are placed on shelf boards 3a of the seedling culture shelves and covered with a light-transmitting shield 9 provided with vent holes 15, and light of a predetermined luminous intensity is projected onto these grafted seedlings from fluorescent lamps 5 through the light-transmitting shield to weld the grafted seedlings 8. The relative humidity in the light-transmitting shield immediately after the grafting is raised by the evaporation of moisture from the rootstocks and the scions, and the rooting of the rootstocks and the scions is thereby facilitated. When the photosynthesis is stimulated, gas exchange between the carbon dioxide gas-containing atmosphere within the closed type structure and the atmosphere within the light-transmitting shield are accomplished to replenish the inner space of the light-transmitting shield with carbon dioxide gas.
