Title: Optical waveguide expanded in mode field diameter and its production
Inventor: YAMADA KIMIMICHI
IPC: G02B6/126
Filed: 1994-03-15
Abstract: PURPOSE:To provide an optical waveguide expanded in a mode field diameter, good in optical coupling characteristic and low in loss and the same production. CONSTITUTION:A glass film for cores is formed on a quartz glass substrate 1. The film is patterned by photolithography and dry etching to the cores 2 of a prescribed size (stage 1). Next, the middle parts of the cores 2 on the substrate 1 are locally heated and melted by a CO2 laser beam 5 and are thereby deformed flat (stage 2). In the succession, the soot which constitutes a clad layer 6 is deposited on the quartz glass substrate 1 and is then vitrified by sintering (stage 3). The clad layer 6 is formed on the surface of the cores after the cores 2 are deformed by heating and, therefore, the mode field diameter of the optical waveguides is expanded without thermally deforming the clad layer 6. A slit 8 for cutting the cores 2 of the parts 4 irradiated with the laser is formed at the optical waveguide 7 with the clad (stage 4) and an optical element is inserted into the slit 8, by which the low-loss flush type optical parts are obtd.

Abstract: PURPOSE:To enable obtaining a film of excellent workability, processability and electrical characteristics, and high strength by causing the film to contain bridged high polymer fine grains having a specific mean grain size and grain size ratio, and a specific structure unit in a molecule. CONSTITUTION:The biaxial oriented polyester film in the title contains 0.01 to 4wt.% of bridged high polymer grains having an ethylene glycol unit of 0.05 to 3.0mum mean grain size ratio and 1.2 to 5.0 mean grain size ratio. Also, the sum of lengthwise and widthwise F-5 values of the film is 22kg/mm<2> or more. Namely, ethylene glycol is contained in a molecule, and bridged high polymer grains suitably deformable due to orientation are contained in the film. In the case of bridged high polymer grains relatively compatible with polyester and having follow-up characteristics for orientation, a gap is hardly generated and high dielectric strength can be ensured. According to the aforesaid construction, it is possible to obtain a capacitor film having excellent mechanical properties, deposition processability, element winding characteristics and electrical characteristics.

Title: Sample transfer device and method for electron microscope
Inventor: MUTO MASAO
IPC: H01J37/20
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To operate a motor by the most suitable driving pulse for a position where a sample is transferred. SOLUTION: A drive command pulse is sent to a pulse generating circuit 26 from a controller 25. The pulse generating circuit 26 generates a driving pulse with the maximum pulse width based on the drive command pulse, and supply it to a motor driving circuit 27. When a torque for a position where a sample is transferred is big, the motor is not immediately operated by the driving pulse, and it starts operating after a considerable delay. An encoder 24 generates an encoder signal after a considerable delay from a rise of the driving pulse. The encoder signal is fed back to the pulse generating circuit 26, and a part of the driving pulse generated after a rise of the encoder signal is cancelled. The pulse generating circuit 26 is narrower than the driving pulse, however it generates a driving pulse with a big width capable of coping with transfer to a position requiring a big torque.
