摘要： PURPOSE:To provide an apparatus having a vessel for holding a fresh flower, an evacuation apparatus for evacuating the vessel and a means for heating the inner wall surface and the inner atmosphere of the vessel, and effective in removing water from a fresh flower within a short time and giving a dust- free dry flower resistant to color fading. CONSTITUTION:A fresh flower 2 is disposed in a vessel 1, the vessel is evacuated with a vacuum pump 20 to =50 deg.C by heating a ceramic plate 10 with a heater 9. The water evaporated from the fresh flower 2 is trapped in a cold trap 13 to prevent the condensation of moisture on the inner wall surface and prevent the rise of the dew point in the vessel. The humidity, temperature and pressure in the vessel are controlled by a sensor 16 in the vessel. Since the above process is performed without using an absorbing material, a clean and dust-free dry flower can be prepared. The dry flower can be used as a food because it is sterilized with heat by the above treatment.

摘要： PURPOSE:To provide an object which has an effect to keep an appreciator amused by changing its shape by temperature and thereby fascinating him. CONSTITUTION:A shape memory alloy 2 changes its form due to an ambient temperature and for example, petals 1 made of the alloy close, if temperature is low, and open if temperature is high. In this case, the alloy is suitable to the preparation of an artificial flower which does not break, if the form changes because the change of the petals is significant. Furthermore, the petals open as the shape memory alloy 20 is warmed by the rising sun, if the artificial flower is deposited at a place where the beam comes in. If the solar heat is insignificant, the artificial flower is placed in a vessel to provide a green room effect. Another way is to heat the flower using a heater which is energized if a photosensor detects light.

摘要： PURPOSE:To eliminate contamination by carrying out primary culture to multiply mycelia in a liquid and doing fructification in a mushroom bed or by culture in log for SHIITAKE (Lentinus edodes). CONSTITUTION:First, a proper amount of seed fungi are extracted from a laboratory dish 1 and the seed fungi 2 are subjected to shaking culture in a liquid medium 4 by using a tube 3. Then shaking culture is carried out in another liquid medium 6 by using a SAKAGUCHI flask 5 and further automatic control culture is done in an another liquid medium 8 by using an automatic control culture tank 7. The control items are pH about 5-6, about 23 deg.C temperature and about 1mmol/l dissolved oxygen concentration in liquid. After suspension of liquid culture, fungi are collected by a centrifugal separator 9, the mycelia are mixed with a medium for culture in a mushroom bed and culture in mushroom bed is carried out to form fruit body.

摘要： PURPOSE:To dry a plant with keeping a natural shape without burying in absorbing material, etc., in case of drying, by making many vent holes in epidermis of plant and drying. CONSTITUTION:Many fine vent holes 2 as small as arising no hindrance on outward appearance of looking in a leaf 1 of plant desired to dry are made by pressing a needle-like material and a plant such as a natural flower 3 is put in a container 4, an electric power is supplied to a heater 5 provided on outer periphery of the container 4 from a heater power source 7 and the container 4 is heated, and simultaneously, a vacuum pump 9 connected to the container 4 through a valve 8 is operated and inside of the container 4 is vacuumized, then water in the plant is uniformly evaporated and a natural shape is kept without any local deformation. Temperature, pressure and humidity in said container 4 are observed by a temperature sensor 10, a pressure sensor 11 and a humidity sensor 12 and observed values are input to a control device 13 thus the heater power source 7 and the valve 8 are controlled by the control device.

摘要： PURPOSE: To obtain a decoration holder for supporting a dry plant rigidly in a holder in which the dry plant can be set/removed easily and repeatedly without decreasing the holding force by embedding a permanent magnet in the holder and securing an attracting body of magnetic body or permanent magnet to a part of a dry plant decoration so that the attracting body is attracted magnetically to the holder. CONSTITUTION: A permanent magnet 1 is covered with a decoration to produce a holder 2 which is then fixed with a string 3 to provide a necklace or fixed with a hook to provide a year ring. A dry plant, i.e., a dry flower 4, subjected to waterproofing by transparent vinyl chloride is applied, to the rear surface thereof, with an attraction body, e.g. an iron piece 4a, for attracting the dry flower 4 to the holder 2. 4b is a click facilitating removal of the iron piece 4a from the holder 2 without damaging the dry flower 4. The attraction body may be a permanent magnet. According to the arrangement, the dry flower 4 can be secured and removed easily.
