Title: Semiconductor device and its manufacturing method
Inventor: MUKAI TAKETERU
IPC: H01L29/66
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To form a plurality of quantum boxes having a different magnitude on the same substrate by a method, wherein a fine crystal having an unequal magnitude in a direction within a face on a face of a semiconductor substrate is disposed in a scattered point form. SOLUTION: A fine crystal body 5 having a large In composition is formed in a region having a small In composition, so as to be distributed on a scattered point. Since an enegy level obtained by electrons and holes in this fine crystal body 5 having many In compositions is lower than that of a peripheral region having a small In composition, upper and lower GaAs cap layers 4 and a GaAs buffer layer 2, the fine crystal body 5 works as a three-dimensional potential well for carriers. As described above, a quantum box 5 for confining a quantum in a three-dimensional direction for electrons and holes is formed. Strain energy in a quantum box layer 3 is changed by a magnitude of lattice mismatching with a underlayer face, and a magnitude of the lattice mismatching is changed, whereby a magnitude of the quantum box 5 can be changed.  Accordingly, the plurality of quantum boxes having a different magnitude can be formed.

Title: Electromagnetic wave shield plate
Inventor: HASEGAWA HIROTERU
IPC: B29K105/20
Filed: 1985-03-29
Abstract: PURPOSE:To obtain excellent various resistant properties and transparency and to prevent deformation, by embedding metal plated synthetic fiber cloth in a synthetic resin molded body based on diethylene glycol bisaryl carbonate. CONSTITUTION:A shield plate 1 is integrally molded from a diethylene glycol bisaryl polycarbonate resin 2 and metal plated synthetic fiber cloth 5 is embedded between one surface 3 and the other surface 4. Two resins divided by the metal plated synthetic fiber cloth 5 are connected through the apertures of the cloth 5 to be integrated. Because the synthetic fiber cloth 5 coming to a conductive net has flexibility and easy deformability even when a molded body having a relatively large dimension is formed, the deformation at the time of molding, the generation of internal stress and strain and the generation of cracks are prevented by this structure and, because a synthetic fiber is used and the strand itself of the conductive net can be made fine, the transparent shield plate giving no sense of incongruity in a case used in OA machinery or a CRT filter is obtained.

Title: Equipment for pumping water up by solar heat drive
Inventor: NISHIZAKI MICHIYOSHI
IPC: F03G6/04
Filed: 1983-04-11
Abstract: PURPOSE:To dispense with electric wiring and make it possible to avoid using onerous energy, by driving an equipment under the supply of solar heat to pump water up. CONSTITUTION:When an arm 6 is inclined so that a sealed reaction vessel 1a and a pumping-up vessel 7a are submerged in a water passage or reservoir, another sealed reaction vessle 1b is heated in the air by solar heat so that the pressure in the vessel 1b is increased and transmitted to a variable-volume vessel 3b to push a coupling bar 4 into another variable-volume vessel 3a. As a result, a pin 5b turns a rod 10 to tilt a weight 11 toward another pumping-up vessel 7 to change the moment about a fulcrum 8 to incline the arm 6 in the opposite direction. Consequently, the pumping-up vessel 7b and the sealed reaction vessel 1a are pulled up to pump up water from the water passage or reservoir. When the other sealed reaction vessel 1b is submerged in the passage or reservoir, the temperature of the vessel is reduced to drop the pressure therein but the temperature of the reaction vessel 1a pulled up in the air is increased. As a result, an action opposite to that mentioned above is performed. A seesaw motion is thus caused without using electric power, as long as the sealed reaction vessels 1a, 1b are heated and cooled.

Title: Mos transistor
IPC: H01L29/49
Filed: 1992-03-23
Abstract: PURPOSE:To reduce the drop in signal voltage when an operating voltage is lowered, by constituting the vicinity of the interface of a gate insulating film in a gate electrode by using semiconductor in which the concentration by conducting impurities is low. CONSTITUTION:P-type poly silicon 105 of low impurity concentration, and a gate electrode of N-type poly silicon of high impurity concentration are formed. P-type low concentration regions 102, 103 are a drain and a source, respectively. When the band of a silicon substrate 101 is flat, positive fixed charges in a gate oxide film 104 are neutralized, so that electrons are stored on the surface of a silicon substrate 101, the gate electrode surface is turned into a depletion layer, and negative accepter ions are formed. When negative charges are applied to the gate and the silicon substrate 101 surface is inverted, electrons are concentrated on the sate electrode surface. As the result, the effective thickness of the gate oxide film at the time of cut-off differs from the thickness at the time of conduction, and this difference exerts influence on a threshold voltage. That is, a high threshold voltage is obtained at the time of cut-off, and a low threshold voltage is obtained at the time of conduction.
