Title: Quantum well structure semiconductor laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/00
Filed: 1985-01-16
Abstract: PURPOSE:To obtain a quantum well structure semiconductor laser capable of making a laser beam oscillate in a short wavelength and at a low thrshole value even in case the quantum well layer is made very thinner by a method wherein graded layers are provided on both sides of the quantum well layer. CONSTITUTION:This quantum well structure semiconductor laser having at least one quantum well layer 4 or more in its main luminous region is constituted into a structure, wherein a first graded layer 3 and a second graded layer 5 are provided on both sides of the quantum well layer 4, the forbidden band width thereof becomes smaller gradually as the graded layers 3 and 5 get nearer the quantum well layer 4 in the film thickness direction of the graded layers and the thicknesses of the graded layers are formed into about 5 Angstrom  or more to 300Angstrom  or less. As there exist the first graded layer 3 and the second graded layer 5 on both sides of the quantum well layer 4, the thickness of the equivalent quantum well layer is formed thicker. As a result, even though carriers to pass through the quantum well layer are generated, the carriers are captured by these graded layers and are immediately pulled back by the internal electric field in the graded layers. Accordingly, even when the thickness of the quantum well layer is made very thinner, the injection efficiency does not worsen because the carriers are captured by these graded layers.

Title: Measuring apparatus for plant weight
Inventor: TSURUOKA HISASHI
IPC: G01G17/00
Filed: 1982-01-20
Abstract: PURPOSE:To enable the measurement of the weight of a plant for a continuous time by arranging a lever, a strain gauge provided at one end thereof and a supporting body for supporting the plant to be measured provided at the other end thereof. CONSTITUTION:The weight of a plant 6 working on a supporting body 1 is transmitted to an elastic body 4 through a lever 2 and a connector 3, on which a strain gauge is applied. A bridge is built up with four of such elastic bodies 2 covering the surface and the back. This permits the weight M of the plant 6 to vary the resistance value of the gauge. When the volume of a submerged part of the plant 6 in a nutriment liquid is expressed by V and the density of the liquid alpha, the weight M' of the plant 6 working on the supporting body 1=M-alphaV. The weight Mg of the root=betaM, where its root is immersed in the chemical. When the density of the root is expressed by gamma, the relationship as shown by the equation on the right holds. Therefore, the weight working on the supporting body 1 is proportional to the whole weight the root 6. The proportion coefficient K is determined from the density alpha of the nutriment liquid, the weight coefficient beta with respect to the whole weight of the plant 6 and the density gamma of the root, and it is possible to obtain each of them separately.

IPC: C25F3/24
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To maintain the polishing speed in a stainless steel as high as possible and to uniformly finish the whole face of the sheet into objective glossiness with high reproducibility by using the stainless steel sheet to be polished as the positive electrode and executing intermittent electrolysis before the amt. to be electrolyzed reaches the prescribed one. SOLUTION: In an electrolytic bath of phosphoric acid series, the stainless steel sheet to be polished is arranged as the positive electrode and a metallic sheet as the counter electrode, and direct current is applied to subject the stainless steel sheet to electrolytic polishing. At this time, intermittent electrolysis in which the electric current is regulated to zero for >=1sec is executed for at least one time before the amt. to be electrolyzed reaches the prescribed one. Thus, the fixation of the pass of the electric current at the generating point of electrolyzing gas is prevented, by which the stainless steel sheet is subjected to high speed electrolytic polishing without generating deterioration in luster and nonuniformity.
