Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To reduce the number of culturing days by repeating, under a specific conditions, the process of impregnating seedlings in a nutrient solution for a fixed period and then simultaneously discharging the nutrient solution from a seedling raising bed so as to quicken the growing of the seedlings. SOLUTION: First of all the seedlings of culturing objects such as moth orchids are supplied with a nutrient solution W being fertilizer so that the nutrient solution is accumulated from the lower side of the seedling raising bed B mounting many seeldings. After impregnating the seedlings in the nutrient solution of the fixed time, the nutrient solution is simultaneously discharged to flow oxygen from the upper side of the bed B into culture soil. Continually, after the lapse of a period corresponding to an accumulated sunshine hours, the cycle starting from the supply of the nutrient solution is repeated to grow the seedlings. It is desirable for additionally contributing to the quickening of culture to very the contents of the nutrient solution according to the growing steps of the seedlings such as a seedling stage, an intermediate seedling state.  It is desirable to provide a dewatering means such as a corrugated sheet 11 at the seedling mounting part of the bed B to cut off contact with the nutrient solution dropped from the seedlings.

Title: Platinum film forming method
Inventor: ZE HYON ZU
IPC: H01L21/44
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To improve the electric characteristics of an element by forming a Pt film on a semiconductor substrate and forming a uniform granular irregularity surface to suppress the hillocks. SOLUTION: On a semiconductor substrate 21, a first Pt layer 22 for a lower electrode of a capacitor is formed. To suppress the hillocks from growing on the surface of the first layer 22, electrons are applied to strike this layer deposited at room temp. to cause a stress therein, thus artificially forming hillocks having approximately a fixed granularly arranged irregularity shape. This prevents eventually growing hillocks, thereby improving the electric characteristics of a high-dielectric const. film.

Title: Dummy load circuit
Inventor: NISHIYAMA MASAHIRO
IPC: H03F1/52
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To reduce the power loss and to improve the power efficiency for a dummy load circuit by switching over the resistance using a dummy resistance having large resistance value to supply the current when the current flowing to the output is increased and then using a resistance having small resistance value to supply the current when the current flowing to the output is reduced, respectively. SOLUTION: When a large current flows to the output, a transistor TR 5 is turned on by the potential difference of a resistance 7 constructing a part of a switch means. Then a current flows through the TR 5 via a diode 1 and a resistance 2. When the current flowing to the output is reduced, the TR 5 is turned off by the potential difference of the resistance 7. Then the current passing through the diode 1 and the resistance 2 turns on a TR 6 via a diode 4. Thus a current flows to the TR 6 via the diode 1 and a resistance 3. Thereby, the current is supplied to the resistances 2 and 3 when the output current is increased and reduced, respectively.

Title: Stacker for paper discharge mechanism
Inventor: UENO IKUO
IPC: B65H31/02
Filed: 1986-11-29
Abstract: PURPOSE:To eliminate the occurrence of a trouble in the discharge of thin paper regardless of an increase in the storage capacity of a stacker by mounting a support plate comprising a thin elastic sheet to the rear plate of the stacker erected aslant in a direction toward a paper discharge roller. CONSTITUTION:A paper sheet 5 when first fed to a stacker 2 is liable to be buckled, but supported with a support plate 15 at the intermediate part thereof, if the sheet 5 is thin, and there is no occurrence of buckling, thereby ensuring the smooth discharge of the paper sheet 5 to the stacker 2. When the stack amount of sheets 6 in the stacker 2 has increased, the support plate 15 is bent downward due to the weight of the sheets 6. As the upper surface of the sheets 6 guiding the sheet 5 comes near a paper discharge roller 1, however, the sheet 5 is free from buckling. And as the stack amount of the sheets 6 increases, the support plate 15 bends in a direction along the rear plate 3 of the stacker 2. Therefore, a sheet storage space at the bottom 4 of the stacker 2 can be secured.
