IPC: C23C16/50
Filed: 1993-06-08
Abstract: PURPOSE:To easily manufacture a homogeneous supperlattice structure composed of the periodic structure of amorphous semiconductors having a large band gap difference between them. CONSTITUTION:In the plasma CVD method which is used for manufacturing an amorphous thin film on a substrate 109 by decomposing a gaseous starting material by impressing an electric field across an electrode 103 and the substrate 109 from a power source 101, a homogeneous supperlattice structure is formed on the substrate 109 by alternately introducing mixed gases prepared by mixing a rare gas and the gaseous starting gas at different mixing ratios into a vacuum vessel 102. For example, an i-type a-Si:H (B) layer is formed to a thickness of 20-100Angstrom  by introducing SiH4. diluted with He to a concentration of 0.5-10vol.% into the vessel 102 and impressing high-frequency power upon the electrode 103 after an i-type a-Si:H (A) layer having a thickness of 20-100Angstrom  is formed as a barrier layer by introducing SiH4 diluted with He to a concentration of 100-500ppm into the vessel 102 and impressing high-frequency power upon the electrode 103. A laminated body of the layers is obtained by repeating the abovementioned operations.

Filed: 1988-06-03
Abstract: PURPOSE:To quickly heat iron scrap to high temp. at high heat efficiency by making injection gas velocity from top blowing lance higher than high temp. gas velocity ascending from a tuyere at furnace bottom of a converter charging the iron scrap. CONSTITUTION:Kerosene from outer tube in the double tube tuyere 2 arranged at furnace bottom of the converter 1 charging the iron scrap 3 and combustion improving gas from the inner tube, are injected to burn the kerosene and generate the high temp. gas. Then, the oxygen blowing is always controlled so that the blowing oxygen velocity V2 shown in the equation II from the top blowing lance 5 is higher than the ascending velocity V1 shown in the equation I for developed high temp. gas (V2>V1). Wherein, in the equation I, F0: bottom blowing oxygen gas flow rate (Nm<3>/hr), F1: gas flow rate except oxygen from bottom blowing (Nm<3>/hr), D: inner diameter of lining brick in the converter (m), in the equation II, F: top blowing total oxygen rate (Nm<3>/hr), N: number of nozzle in the top blowing lance, L: oxygen blowing height (m) (distance from top surface of scrap to the lance tip), theta: inclining angle ( deg.) of the lance hole. By this method, heat transfer time to the iron scrap is secured and exchange of heat is facilitated.

Title: Magnetic disk
Inventor: MURAKAMI YOICHI
IPC: G11B5/02
Filed: 1990-05-28
Abstract: PURPOSE:To easily record data with a high density by using a high-density magnetic recording medium thick coated with a single layer and forming what is called a buffer layer between a data recording layer and a saturation recording layer of a servo signal at the time of forming these layers under and on this single layer respectively. CONSTITUTION:A magnetic head 3 has such gap length GL1 that the surface of a high-density magnetic recording medium 1 having a thickness D0 can be magnetized up to a depth D1. This magnetic head 3 is used to erase magnetization in the area from the surface to the depth D1 of the high-density magnetic recording medium 1 subjected to saturation recording. As the result, the area of D0-D1 in the lower side is left as the saturation recording layer of the servo signal. This depth D1 satisfies relations D0>>D1>>D2 where D2 is the depth (effective magnetization depth) up to which a data signal is recorded and reproduced on the surface at the time of actual use. The buffer area of D1-D2 is provided in this manner. Thus, the servo signal and the data signal are easily separated from each other, and data can be recorded with a high density by the magnetic head having a short gap length because the gap length is properly selected.

IPC: G06F9/44
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To execute dynamic downcast processing or cross cast processing in execution within an object-oriented programming language such as a C++ language. SOLUTION: A compiler generates data structure (200) during compiling and a routine within a language supporting library accesses to generated data structure (200) at the time of execution to execute a dynamic cast.

An offset 218 within an object description 204 is calculated for each sub-object 206 included in the object. An identifier 248 concerning each sub-object is stored in data structure 200 with its offset 250. Each virtual table 214 additionally stores the offset 218 of the corresponding sub-object 206. Cast processing is executed at the time of execution by using RTTI data structure 216.

Title: Excavation angle control device
Inventor: MIYAUCHI KENICHI
IPC: E02F3/43
Filed: 1991-05-14
Abstract: PURPOSE:To automatically adjust the angle of an excavating body such as a bucket and simplify its operation. CONSTITUTION:An arm 4 is connected to a boom 3, a bucket 5 is fitted to the arm 4, and their angles are changed by hydraulic cylinders 6, 7, 8. An angle sensor 20 is fitted to the bucket 5. The angle sensor 20 detects the angle of the bucket 5 against the earth gravitational force and outputs it to a control means. The control means can set the angle to be held by the bucket 5 and automatically adjusts the set angle of the bucket 5 based on the detected angle from the angle sensor 20. The angle of the bucket 5 is surely adjusted even if the angles of the boom 3 and the arm 4 are fluctuated because of the angle adjustment with the earth gravitational force used as a reference.

Title: Sensor mounting structure for piston behavior analysis
Inventor: AKEMOTO KISHIYU
IPC: G01B7/00
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of heat in a sensor which detects behavior of a piston. SOLUTION: A pair of upper sensors 8a and lower sensors 8b are arranged and installed on the right and the left by interposing a piston 4c between them. The sensors 8a, 8b are installed so as to cross water jackets 10 which are formed so as to externally surround cylinder liners 3c which demarcate a cylinder chamber which receives and houses the piston 4c. Thereby, since the housing case of a sensor crosses the water jackets, the sensor can be cooled via the housing case, the influence of heat from a combustion chamber with reference to the sensor can be reduced, and the detection accuracy of the sensor can be increased.
