Title: Superconductive coil
Inventor: FUJIOKA TSUTOMU
IPC: G21B1/11
Filed: 1985-05-20
Abstract: PURPOSE:To reduce the cost by spirally winding as SUS reinforcing tape having a distribution of the thickness calculated in response to an electromagnetic force distribution in the radial direction of a coil together with a bundle conductor, thereby compactly forming the coil. CONSTITUTION:An SUS reinforcing tape 1 having a distribution of the thickness in a radial direction is wound together with a bundle conductor 2. The thickness distribution is decided as below by calculating in advance the electromagnetic distribution of the radial direction of a coil. A hoop electromagnetic force component of the electromagnetic component of the coil is generally dominant, and the component may be mainly considered in designing the stress of the coil. It is normal that the radial distribution of the component reduces inversely proportionally substantially to the square of the diameter from the inner periphery to the outer peripheral side as shown in the drawings. Accordingly, the thickness distribution t1, t2, t3... of the minimum necessary limit capable of sufficiently supporting the electromagnetic force is determined by the reinforcing effect of the tape 1 on the basis of the distribution.

Title: Optical amplifier and optical amplification method
Inventor: OISHI YASUTAKE
IPC: H01S3/08
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To realize low noise and high gain and obtain flat gain, by constituting an amplifier of optical amplification medium selected out of a group composed of fluoride glass and the like, and exciting erbium by specified at least one wavelength. SOLUTION: In order to obtain gain by exciting<4> I/11/2 level, amplification characteristics are measured by forward excitation using a pumping light having a wavelength of 970 nm between 960 nm and 980 nm. The result is as follows; when the incident signal intensity is -30 dBm and the pumping light intensity is 132 mW, the gain at 1.53 μm is 30 dB, and the NF(noise figure) is 4.5 dB. At 1.55 μm, the NF is 3.5 dB. When the above fiber is excited by a pumping light of 1.48 μm, the NF is higher than or equal to 5 dB at 1.55 μm. Hence the improvement of NF is at least 1.5 dB. When the wavelength of a pumping light is set as an arbitrary wavelength between 960 nm and 978 nm, it can be confirmed that the NF is improved (decreased) as compared with the pumping at 1.48 μm.

Filed: 1988-04-28
Abstract: PURPOSE:To contrive the improvement of mass production efficiency of an oxygen sensor by changing the control characteristic of feedback control being based on a difference between response times of the oxygen sensor under its different temperature measured during the actual air-fuel ratio control of an engine. CONSTITUTION:A feedback control means, being based on a signal from an oxygen sensor measuring concentration of O2 in exhaust gas from an engine, performs a feedback control of air-fuel ratio of a mixture so as to obtain the target air-fuel ratio. This sensor forms a protecting film of small porosity, but an individual difference is provided between the porosity, while because the characteristic changes generating blocking by aged deterioration, the response time required for a change from the lean to the rich of the output is measured by a measuring means in two different temperatures, and in accordance with a difference between these response times, the control characteristic of a feedback control means is changed by a control characteristic changing means. Thus enabling the control characteristic to be set optimum for porosity of the protecting film in the present of time, the oxygen sensor enhances its mass production efficiency while being able to correspond even to the aged deterioration.

Title: Hair tension measuring mechanism in hair diagnostic instrument
Inventor: FUJIWARA MICHINOBU
IPC: G01N3/00
Filed: 1987-04-30
Abstract: PURPOSE:To accurately measure the strength and the elongation of a hair including a cuticle by sandwich-wise holding a hair at both ends first and second slide blocks to stretch the hair and fixing the first slide block and a frame to each other by a spring member. CONSTITUTION:A hair H is sandwich-wise held by the sandwich-wise holding unit 24a of a first slide block (first SB) 24 and the sandwich-wise holding unit 27a of a second slide block (second SB) 27. The first SB 24 and a frame 20a are fixed to each other by a spring member 25. A rotating shaft 23 is rotated to move the second SB 27 to the right. At this time, the first SB 24 is pulled by the tension of the hair H to move with the second SB 27 and the spring member 25 is elongated. The breaking strength of the cuticle (epidermis) of the hair is measured by the movement of the first SB 24. Since the hair is suddenly elongated after the breakage of the cuticle, the first SB 24 does not move to the right and only the second SB 27 moves. A strength and an elongation at which the whole hair is broken are obtained. Accordingly, the strengths and the elongations of the cuticle of the hair and the whole hair can be accurately measured.
