Title: Tube for reinforcing coated optical fiber
Inventor: SUZUKI ATSUSHI
IPC: G02B6/44
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To reduce shrinkage due to a temperature change of the environment and to prevent the deterioration of transmission characteristics at low temperature by using a polyester elastomer containing polybutylene naphthalate as a hard segment as a tube material and specifying the average coefficient of expansion in the longitudinal direction. SOLUTION: The tube 1 for reinforcing a coated optical fiber is formed from a polyester elastomer containing polybutylene naphthalate as a hard segment. Since the average coefficient of linear expansion in the longitudinal direction in the range of -40 to +20 deg.C is reduced to <=0.7×10-4(1/ deg.C) by regulating the soft segment contained in the polyester elastomer, shrinkage at low temperature is suppressed and the increase of loss at low temperature is reduced.

Title: Chemical reduction process
Inventor: MORI TOSHIKATSU
IPC: C01D5/14
Filed: 1979-03-12
Abstract: PURPOSE: To promote reduction reaction rapidly even under a moderate condition by subjecting substances and reductive gas in aqueous solution to a catalytic reaction over a water-repellent solid catalyst.  
     CONSTITUTION: A reducible ion or molecule present in aqueous solution is directly brought into contact with a reductive gas, e.g., carbon monoxide, hydrogen, etc., introduced into the aqueous solution in the presence of a water-repellent solid catalyst, prepared by treating a hydrophilic catalyst by a water repelling treatment or by using a water-repellent supporter. Whereupon, reduction reaction is rapidly promoted without covering all surface of the catalyst with the aqueous solution because the reductive gas is adsorbed in the surface of the catalyst and easily comes into contact with the reducible substance.

Title: Method for rolling titanium alloy
Inventor: NAGAI ISAO
IPC: B21B3/00
Filed: 1989-02-08
Abstract: PURPOSE:To suppress defects, such as surface cracks and rough surfaces, by specifying the rolling reduction per pass and subjecting the stock sheet of a titanium alloy to light draft rolling at specific passes or above to form finer surface layer parts, then rolling the sheet to a target sheet thickness at the time of rolling the above-mentioned stock sheet in a two- phase region of (alpha+beta). CONSTITUTION:The surface layer parts which are exposed to a high temp. when the titanium alloy is heated to a high temp. have the crystal structure coarser than in the central part of the sheet thickness of the stock. The degree of deformation varies at the grain boundaries and in the grains with respect to the same rolling force if the titanium alloy of this state is rolled under the large rolling force. Malleability is inferior at the grain boundaries where impurities condense and, therefore, if the rolling force exceeds a certain value, cracks are liable to arise at the grain boundaries and the surface cracks, rough surfaces, etc., are generated. The titanium alloy heated to a high temp. is subjected to the light draft rolling at <=5mm rolling reduction per pass and >=3 passes in the two-phase region of (alpha+beta). The deformations are concentrated to the surface layer parts in this way, by which the coarse crystal grains of the surface layers and made into the finer grains and the condensed impurities are dispersed to the grain boundaries. The surface layers act as buffer films and the generation of the defects, such as surface cracks and rough surfaces, is thus prevented.

Title: Phase decision apparatus
Inventor: SUZUKI TERUO
IPC: G01R25/00
Filed: 1984-02-21
Abstract: PURPOSE:To enable accurate decision on the phase whether it is single or three phase by judging the phase based on a line voltage signal and a phase current signal. CONSTITUTION:Line voltages P12 and P32 are converted into line voltage signals V12 and V32 of a square waveform with comparators 1 and 2 and fed to single/three phase discriminator section 10, which sends a discrimination signal G of H level to a switching section 20b when judging it as single phase while that of L level, as three phase. When single phase is found, the switching section 20b sends a signal V12 to an input terminal D of an FF30 while when three phase is found, it sends a line voltage signal Vs delayed in the phase by 90 deg. with a delay section 20a to a terminal D of the FF30. Depending on the lag or advance of the phase between the voltages V12 and Vs and the phase current signal I obtained by the conversion of a phase current I1, an H-level signal is outputted from an input terminal Q of the FF30 when the phase is in lag while an L-level signal is outputted when it is in advance. Thus, whether the power source is single or three phase, it can be automatically judged by lag or advance in the phase. As the phase current I1 is amplified to a specified level with an amplifying section 40, the magnitude of the phase current I1 will not affect the decision on the phase however it may be limited.
