Title: Manufacture of semiconductor quantity dot
Inventor: KAWAMOTO SHIGERU
IPC: H01L21/20
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To uniformly form a quantum dot at the position of a fine thin hole over a wide range. SOLUTION: A fine thin hole 12 is formed on the surface of a semiconductor layer 11 in advance using such nano probe as electron means and STM(scanning- type tunnel microscope), and then a material for terminating the surface of the semiconductor layer 11 is applied for forming a termination film 13 on the surface, and then a quantum dot 14 is formed only on the fine thin hole 12 by the crystal growth method. In this case, when the fine thin hole is to be formed, a surface is generally activated (dangling bond is exposed to the surface). Also, the degree of activation accompanies local nonuniformity, so that a quantum dot may not be formed at a fine thin hole to be formed due to the nonuniform surface diffusion of a growing atom when the crystal growth is made as it is.  The present invention has an advantage where the quantum dot 14 is formed uniformly over a wide range at the position of the fine thin hole 12 by terminating the surface with the termination film 13 before the above crystal growth.

Abstract: PURPOSE: To vibrate a semiconductor laser pickup efficiently in a focus direction, tracking direction and tangential direction, by arranging driving mechanism parts around the pickup.  
     CONSTITUTION: Semiconductor laser pickup 1 is fitted in center hole 4b of support 4 at equal intervals from driving mechanism parts 2A, 2B, 2C, and 2D, and driven by driving coils 12 on the reverse surface of arm part 4a.

Filed: 1988-06-28
Abstract: PURPOSE:To improve the spraying efficiency of chemical liquid significantly by installing a bifurcated atomization nozzle for spraying chemical liquid, which is positioned obliquely downward from an atomization orifice, on a chemical liquid supply pipe and setting the atomization orifice so that the mist of the chemical liquid is ejected forward and backward in the movement direction of the chemical liquid supply pipe. CONSTITUTION:A chemical liquid atomization device 1 is positioned above a plant 9, and the chemical liquid is sprayed from the atomization orifice 7 of an atomization nozzle 4 in a bifurcated state, that is, C obliquely downward in the forward direction and D obliquely downward in the backward direction. During the above action, a chemical liquid supply pipe 3 is horizontally moved above fruits or trees from a position E to a position E. The chemical liquid sprayed from the atomization orifice to an obliquely downward point C in the forward direction falls over the right half section R of the plant from the bottom to the top sequentially. Next, if the atomization nozzle 4 passes right above the plant 9, the chemical liquid sprayed from the atomization orifice 7 to an obliquely backward point D in the backward direction falls over the left half section L of the plant 9 from the top to the bottom following the movement of the chemical liquid supply pipe 3. Thus the chemical liquid is uniformly sprayed over the plant 9.

Title: Conduit tube apparatus for floor slabs
Inventor: KINOSHITA HIROMI
IPC: H02G3/38
Filed: 1988-06-27
Abstract: PURPOSE:To lower the thermal conductivity of an apparatus and to prevent the temperature on the floor surface side of a floor slab from rising due to a fire starting below said floor slab by providing upper and lower conduit tubes with thin-wall parts. CONSTITUTION:To form the conduit tube apparatus for a floor slab 1, the lower part of an upper conduit tube 6 is provided with a plurality of thin-wall parts 20. Said thin-walled parts 20 are formed by annular grooves. The thermal conductivity of an apparatus falls at said thin-wall parts 20, because the cross- sectional area of said upper conduit tube 6 becomes smaller. Therefore, it is possible to decrease the rise of a temperature on the floor surface side of said flow slab 1 due to a fire, etc., below the floor slab 1.

Abstract: PURPOSE:To efficiently absorb the torsional vibration over the whole high and low ranges by arranging a weak torsional spring mechanism between a plurality of covers and one hub and arranging a strong torsional spring mechanism between a plurality of covers connected to the hub and the other hub. CONSTITUTION:The torque transmitted to each cover 2, 3 is transmitted to a hub 7 through the first torsional spring mechanism 44, and after transmitted to a hub 13 through the second torsional spring mechanism 45 from each cover 4, 5, the torque is transmitted to an output shaft. Each spring 8, 15, 16, 35 is compressed by the force corresponding to the transmission torque, and each cover 2, 3 is twisted with respect to the hub 7 and each cover 4, 5 is twisted with respect to the hub 13 by the angle corresponding to the compression amount. During the time when the transmission torque is small, the torque vibration is absorbed by the first torsional spring mechanism 44. When the transmission torque increases, the compression of the first torsional spring mechanism 44 is suppressed by the stopper mechanisms 22 and 23, and the torque vibration is absorbed by the second torsional spring mechanism 45.

Filed: 1994-07-15
Abstract: PURPOSE:To enhance the preservability of a recorded image, to prevent the skin fog due to external pressure at the time of handling and to improve the sealability by incorporating water absorbing urethane polymer having film forming capacity in a protective layer of a thermal recording medium. CONSTITUTION:Water absorbing urethane polymer having a film forming capacity to become a binder is incorporated in a protective layer provided on a thermal color developing layer containing a color developing component for color developing due to reaction at the time of heating. The polymer is contained by 1 to 30wt.% with respect to the entire binder in the protective layer. If it is less than 1wt.%, the effect of sealability is not exhibited, while if it is 30wt.% or more, the sealability is improved, but the performance of the protective layer is not only lowered, but also sticking, piling easily occur. Accordingly, since the polymer is used as the part of the binder used in the protective layer, the decrease in the protective performance is suppressed to the minimum limit and vermilion ink, stamp ink, etc., is received and absorbed, excellent sealability is obtained.
