Inventor: KOGURE TAKESHI
IPC: C07F17/00
Filed: 2000-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for synthesizing a metallocene compound on an industrial scale in high purity and high yield by solving problems that when a metallocene compound, which is scarcely soluble in an organic solvent, is synthesized, a large amount of organic solvent is used for extracting the complex, and the yield is lowered due to decomposition caused by washing with an alcohol.

IPC: G06Q30/06
Filed: 2000-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a server for controlling the stepped performance of simple evaluation for performing evaluation without performing any complicate work and detailed evaluation for performing scrupulous evaluation. SOLUTION: Performance data for viewing from a control server are viewed at a terminal side so that a composition can be evaluated, and the evaluated contents are transmitted to the control server, and this series of operations are performed. The viewing at the terminal side is performed by reproducing the performance data for viewing received from the control server by using a terminal sound source circuit or a sound system. Two step methods are used for performing the evaluation, and the first method is to perform viewing (first viewing) only in a short time, and to perform simple evaluation (first evaluation) by a selecting means. When the performance of the next scrupulous evaluation is desired by a user, detailed evaluation (second evaluation) capable of scrupulously evaluating the music melody, lyrics, singing skills, and performance skills is performed. As for the scrupulous evaluation, the viewing (second viewing) in a longer time than that of simple evaluation can be performed. When the detailed evaluation is not desired, the evaluation of the next composition is performed.

Title: Abnormality detection method for gas meter and gas supply
Inventor: NUKUI KAZUMITSU
IPC: G01F1/00
Filed: 2000-09-21
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality detection method for a gas meter and gas supply enabling enhancement of reliability in decisions related to warning operation. SOLUTION: CPU 12 checks that the absolute value of a difference in a flow rate ΔQS is equivalent to or more than that of reference flow rate QSK (|ΔQS|>=QSK) and then sequentially detects 'first decision shift state' where decision for gas G consumption state shifts from 'no flow rate change' to 'flow rate changed', and next 'second decision shift state' where it shifts from 'flow rate changed' to 'no flow rate change'. At this time, CPU 12 determines that a gas utensil 1 has operated when the difference in flow rate ΔQS varied within forward area during 'first decision shift state'-'flow rate changes'. Thus any operation of gas utensils can precisely be recognized at any time, so reliability in decision regarding warning action performance will be enhanced.

Title: Vibroscope
Inventor: HIROTA KAZUO
IPC: G01H17/00
Filed: 2000-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a vibroscope that reduces random noise. SOLUTION: The vibroscope main body 1 is brought into close contact with the inside of a cooling hole 3 of a neutron reflector 2 by a spring 4. The spring 4 is fixed to a sleeve 6 tapered in the main body 1 with a fixing metal 5. The sleeve 6 is tapered to get larger in its diameter from the upstream side toward the downstream side with respect to the flow 7 of cooling water. The shape of the main body 1 is made to have a narrow flow passage in its downstream compared with that in its upstream, by this constitution. Force reverse- directional to vibration in a vibration accelerometer is thereby applied by inertia of a fluid when a vibroscope is vibrated even at a small extent of vibration. The vibration is damped thereby, and a random vibration level caused by turbulence of the flow is reduced to reduce a noise on measurement as an effect thereof.
