Inventor: SATO TAKESHI
IPC: C05G3/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To save the handling time of fertilizing work by including phosphoric fertilizer required in a farm in a culture soil. SOLUTION: Mat-shaped culture soil 5 is produced by phosphoric fertilizer particles (citric soluble phosphate concentration being 35wt.% and water soluble phosphate relative containing quantity being 5.7) and a water holding material (the mixture of a vermiculite with a peat-moss). The mat-shaped culture soil is put in the base part of a seedling box 7 and, on it, the uniform mixture of non-manure soil with seedling raising chemical fertilizer (containing nitrogen, phosphate and a potash) is filled as a bed soil layer 9. When seeds 10 are sowed on the seedling raising culture soil D, the grown-up seedling becomes a state where the phosphoric fertilizer particles are held in a root part.

Title: Picture processing unit
Inventor: KOBAYASHI KAZUTO
IPC: H04N1/40
Filed: 1990-04-06
Abstract: PURPOSE:To prevent picture quality of a character part from being deteriorated due to occurrence of moire by discriminating a character and a dot of a character picture whose dots are formed as background, applying low pass filter processing to a discrimi nated dot, bringing the dots entirely to a white level area and applying binary processing to the character part only into white and black levels. CONSTITUTION:A picture signal inputted from an input terminal 11 is inputted to a main scanning direction Fourier transformation section 12, a subscanning direction Fourier transformation section 15, a low pass filter 19 and a selector 20. A comparator 13 uses a threshold level generated from a threshold level generating section 14 to binarize an output of the main scanning direction Fourier transformation section 12. The subscanning direction Fourier transformation section 15 calculates power of a specific frequency f1 in the subscanning direction and outputs the result. A discrimi nation section 18 discriminates the picture and a selection signal S to the selector 20 based on power intensity PM at a main scanning direction frequency f1 being an output of the comparator 14 and a power intensity PS at a subscanning direction frequency f1 being an output of the comparator 16. The selector 20 selects and outputs either an input power supply or an output of the low pass filter 19 based on the selec tion signal S being the output of the discrimination section 18.

Abstract: PURPOSE:To prevent the lowering of light emitting efficiency and lessen threshold current density, by inserting a layer having a forbidden band width that is larger than that of a clad layer as a barrier layer between an active layer and the clad layer. CONSTITUTION:After forming a laminating structure consisting of: a buffer layer 2, a first clad layer 3 of one conductivity type, a first barrier layer 4 of the conductivity type, an active layer 5, second barrier layer 6 of the opposite conductive type, a second clad layer 7 of the opposite conductive type on a semiconductor substrate 1, a semiconductor light emitting device covers the upper surface of the second clad layer 7 with an insulating layer 8 and forms an electrode 9 by providing a window in the electrode part. Then, another electrode 10 is formed below the semiconductor substrate 1. A forbidden band width of the first barrier layer 4 is larger than that of the first clad layer 3 and the forbidden band width of the second barrier layer 6 is larger than that of the second clad layer 7. This configuration hinders the overflow of carriers from the active layer 5 to the first and second clad layers 3 and 7 and then, not only improves light emitting efficiency but also lessens the threshold current density.
