摘要： PROBLEM TO BE SOLVED: To make it possible to reduce the insertion loss and to rotate an optical fiber >=360 deg. in spite of being machined M×N type rotary optical switch. SOLUTION: A circular hole 2 is perforated on the center of a board 1, an analog type clock mechanism 6 is inserted into the hole 2 so that a needle 5 points out the outer peripheral part of the hole 2. A fiber 8 is fixed to the needle 5 and the base end part 8b of the fiber 8 is extended up to a position just above the mechanism 6 and cut off. A cut part 27 is inserted into a capsule 11 filled with a refractive index matching agent 10, the needle side base end part 8b is rotatably set up and a base end part 8c on the opposite side of the needle is fixed together with the capsule 11. Plural V-shaped grooves 4 are radially formed on the base 1 and fibers 7 are connected from the halfways of the grooves 4. When the needle 5 is rotated, the fiber 8 connected to the needle 5 is engaged with the groove 4. When the fiber 8 is engaged with the groove 4, an electromagnet 13 is turned on and a cover 3 is stuck close to the base 1 to press the fiber 8 into the groove 4. A part between tip parts 7a, 8a is filled with a refractive index matching agent 25.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a glass film using a novel plasma CVD device which can effectively restrain tensile stress of a glass film formed on a substrate. SOLUTION: A glass film G is formed on a substrate 1 while producing ion sheath or an enough amount of ion on the substrate 1, by providing a high frequency power supply 5 in a lower electrode 2 side and generating high frequency of at least 380 kHz or higher from the high frequency power supply 5. Consequently, compression stress is generated in the glass film G formed on the substrate 1 and works to offset tensile stress. Therefore, the original tensile stress of a glass film is greatly restrained, and cracks of the glass film G and warp of the substrate 1 can be effectively prevented.

摘要： PROBLEM TO BE SOLVED: To provide an inductively-coupled radio-frequency plasma CVD apparatus which can bury an interval between lines having an aspect ratio of 2 or more on a substrate, with less particles, and to provide a method for manufacturing a glass film using the apparatus. SOLUTION: One or more of ring-shaped gas flow-out pipes 112 and 120 are provided, one or more of nozzle-shaped gas flow-out pipe 119 are provided, a mixture gas of TEOS and oxygen is made to flow out from the pipes 112, 120 and 119, and oxygen is made to flow out from the pipe 112. Thus, a plasma is generated not only a space under a coil 104 but also even in a space above a lower electrode 107. For this reason, only oxygen ions or oxygen radicals can be made to flow out from the pipe 112 provided below the coil 104. As a result, formation of a thick SiO2 film in a region under the coil 104 can be avoided, and particle generation in the region under the coil 104 can be prevented.
