Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To reduce a bit error by suppressing phase noise from a local oscillator. SOLUTION: Mixers 2, 3 are in use and mix an input signal with an orthogonal 480MHz signal from a local oscillator 4 in two paths. Base band signals from I and Q paths are fed to an A/D converter 8 via the mixers 2, 3 and amplifiers 6, 7. A processor 9 modulates received data and checks errors and produces a frequency reference signal controlled by a costas loop 10 in response to the I and Q signals. The costas loop 10 applies multiple processing to the I and Q signals and an error output of the multiplier is used to make synchronization with the reference signal frequency to reduce the error. A phase error is corrected and the reference frequency signal is fed back and the frequency of the local oscillator 4 is controlled by a 2nd phase locked loop 11.

Inventor: UEDA TETSUJI
IPC: G02B6/24
Filed: 1992-07-17
Abstract: PURPOSE:To process an end surface by one process of ferrule cutting by a blade as to a connector for optical communication. CONSTITUTION:A brittle material is used for a ferrule 1, which is cut with the blade 7 in consideration of the width alpha of the blade for ferrule cutting and the width beta of a cutoff part in addition to the length of the beveled part 2 of the ferrule tip end part to make the ferrule 1 have the length gamma of a necessary beveled part 2a left. Consequently, when the optical connector is assembled, an optical fiber 5 at the ferrule front end surface part need not be protected by applying an adhesive to the ferrule end surface part and adhesion removal by grinding is not performed, so the process is completed in a certain time irrelevantly to the amount of the adhesive on the end surface. Further, the length of the ferrule 1 can be controlled with the setting position of the blade, so the length of the ferrule 1 can easily be controlled.

Inventor: KATO YOSHIAKI
IPC: B21C3/14
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce refuse attached to a wire, which has been generated at the time of the wire drawing, and to make a surface defect on the wire hard to generate. SOLUTION: At least on the one side on the wire inlet or the wire outlet of the die box 1 in which a wire drawing die 3 has been arranged, a jetting nozzle 5 injecting detergent oils 4 toward the inlet part 11 and the outlet part 12 of the die, is provided, and a drain port 6 draining the detergent oils 4, is provided. Consequently, the refuse generated at the time of the wire drawing, which is accumulated in the inlet part 11 and the outlet part 12 of the die 3, is removed by the detergent oils. Therefore, the generation of the surface defect caused by the attachment of the refuse generated at the time of the wire drawing, is suppressed, and it can cope sufficiently with making an enamel film thin.  Also, when using the detergent oils 4 while circulating it by cleaning with a small tank 8 for the detergent oils, it is advantageous to the improvement of the quality of the wire 10 because in the small tank 8, a filter 7 can be easily changed. Further, the refuse generated at the time of the wire drawing, which exists in oil for the wire drawing, is decreased, the frequency of the change of the filter in a large tank for the oil for the wire drawing, is decreased as well, and a productivity is improved.

Title: Manufacture of thin film capacitor
Inventor: OTSUKA TAKASHI
IPC: H01L27/04
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To form a conductor film without causing abnormal grain deposition or sharp ruggedness, suppress the current leakage and avoid reduction of a dielectric film at forming of this film, by oxidizing the surface of electrode layers under the condition that an oxidation and disproportionation reactions occur at the same time. SOLUTION: At an Si substrate 1 heated at a low pressure in a closed vessel, an Rh oxide conductor layer 5 is formed on the surface of an electrode film 4 such that a part of the conductor layer 5 being formed on the film 4 evaporates from this film 4 by a disproportionation reaction as RuO4 in a gaseous form, and hence the internal stress of the conductor layer 5 is relaxed in the compressing direction to form a flat surface of the layer 5 without causing large grain precipitates thereon, thus suppressing the current leak and avoiding reduction of a dielectric film 6 at forming thereof.
