Title: Optical amplifier
Inventor: KAWAMOTO KIMIO
IPC: H01S3/06
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To improve the amplification factor and efficiency of an optical amplifier and to reduce the size of the amplifier. SOLUTION: In an enclosure 10, an optical fiber 40 is laid along the x-axis direction which is the propagating direction of a signal light laser. The core of the optical fiber 40 laid in the enclosure 10 is doped with erbium at a high concentration. In front of many light emitting diodes 20, a collimator lens 30 is positioned. On the internal upper surface of the enclosure 10, a semicircular reflecting member 50 is positioned. In addition, on the internal bottom face of the enclosure 10, another reflecting member 51 is formed by vapor-depositing aluminum. Excitation light rays radiated from the light emitting diodes 20 are condensed to the core of the optical fiber 40 through the collimator lens 30. In other words, since the diodes 20 are arranged along the x-axis direction, the excitation light rays are linearly condensed along the x-axis direction. Consequently, the inverted population of electrons is formed uniformly in the x-axis direction.

Title: Inclination sensor
Inventor: TAKATSUKA TOSHINORI
IPC: G01C9/10
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a tilt sensor which has a reduced number of components, an improved assembling workability, and possibility for miniaturization. SOLUTION: Two sets of magnetic sensors 11 are disposed symmetrically along axes X, Y. A spherical magnetic block 13 adjoins a nearly central portion of a magnet 12 where its flux density is maximum by only an attractive force due to the magnetic force of the magnet 12. Owing to the attractive force, the magnetic block 13 normally locates below the center of the magnet 12. When an object tilts, the magnetic block 13 easily moves to change the surrounding magnetic field, causing the magnetic sensors 11 to change their outputs. This allows the number of components such as case, etc., needed for the conventional tilt sensor to be reduced and eliminates the case bonding (connecting) step in the manufacturing process, resulting in an improved assembling workability. Thus, a tilt sensor capable of being miniaturized can be built up.

Title: Casting simulation unit, casting simulation method, casting simulation program, and computer readable recording medium with stored casting simulation program
Inventor: SAKAI KAZUHIKO
IPC: G06F19/00
Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To accurately simulate a shifting position in a minute closed range when molten metal flowing in a casting is simulated. SOLUTION: In the case that the detected closed region is not larger than a prescribed volume or not higher than a prescribed pressure, by simulating (S1-S3) the molten metal flowing and detecting (S4) the closed region formed by the molten metal flowing, the closed region is replaced with a virtual grain having zero of the volume and zero of the mass (S5) and thereafter, the virtual grain is shifted along the molten metal flowing (S6).  In this way, even in the case of becoming impossible to stably succeed a flowing body calculation using a back pressure calculated result in the conventional simulation because the volume in the closed region becomes too small or the pressure in the closed region becomes too high, the molten metal flowing can accurately be simulated to the last by making use of the virtual grain of this closed region, even in the case of applying to the actual casting having complicated shape.
