Abstract: PURPOSE:To prevent oxide and the like from attaching a semiconductor substrate surface on which a PN junction is formed, by a method wherein a gas containing impurity is introduced in a reaction furnace, the above PN junction is formed by diffusing the impurity on the semiconductor surface, and then an epitaxial layer is formed on the semiconductor substrate in the reaction furnace. CONSTITUTION:A substrate 22 is heated by a heating equipment, and hydrogen phosphide is supplied together with H2 gas from a material gas supplying equipment 12. Phosphorus in the hydrogen phosphide is N-type dopant to turn the Si semiconductor into N-type. By diffusing the phosphorus from the surface of the substrate 22, the surface layer of the substrate 22 is turned into N<+> Si semiconductor, and a PN junction is formed between the above N<+> Si semiconductor and the original P-Si semiconductor. The substrate 22 on which this PN junction is formed operates as a first solar cell. Next, on the substrate 22, GaP, distorted superlattice, and a buffer layer 32 composed of distorted superlattice are formed by epitaxial growth method. Thereon a PN junction is formed by semiconductor layers 34, 36, and a second solar cell is constituted.

Title: Mri apparatus table positioning method and mri apparatus
Inventor: ODA YOSHIHIRO
IPC: G01R33/30
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To ensure table positioning for aligning the part of interest of a subject with a magnet center. SOLUTION: Three-plane real-time scans are performed whereby an axial image Sa, a sagittal image Ss, and a coronal image Sc are obtained in real time, and each image is displayed as a table positioning image. An operator views each image and controls the movement of a table so that the position of a part of interest three-dimensionally coincides with a magnet center. In this case, a scan parameter and the transfer characteristic of an RF/NMR signal can be varied as necessary. Thus, the table is moved as the operator views the actual position of the part of interest in the real-time images on three orthogonal planes, ensuring that the position of the part of interest three- dimensionally coincides with the magnet center.

Abstract: PROBLEM TO BE SOLVED: To stabilize tracking servo after rough seeking by changing the time after the completion of the start of a reproducing means before follow-up control is applied in order to read out the recorded information of a recording medium in the case the reproducing means is moved to a prescribed position. SOLUTION: The time after timing up of the prescribed time value until the read out data is thereafter judged to be corrected by applying tracking is measured after the end of the movement of a pickup 1.
