Title: Abnormality detecting device of elevator
Inventor: YAMAKI MASAMITSU
IPC: B66B5/02
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To reduce cost, to improve maintainability, and to surely and correctly detect presence/absence of an abnormality accompanied by the oscillation of a governor rope. SOLUTION: The transverse oscillation generated in a car side governor rope 2a is detected by a vertical acceleration detecting means 6. After the detected signal of the perpendicular acceleration is amplified by a detected signal amplifying means 7, the transverse oscillation index value is calculated by a transverse oscillation index value calculating means 8. The transverse oscillation index value is calculated by applying the correlation between the vertical vibration of an urging weight 4 and a tension pulley which is obtained by experiments, etc., in advance, and the transverse oscillation of the governor rope 2a.  Finally, a transverse oscillation judging means 9 judges whether or not the risk of the traveling obstacle is present based on the transverse oscillation index value, and the signal to express the result of judgment is transmitted by a judged result transmitting means 10 to external or non-indicated control equipment.

Title: Sealing device between thermally-extensible segments
Inventor: KAWAIKE KAZUHIKO
IPC: F16J15/06
Filed: 1983-06-17
Abstract: PURPOSE:To prevent the lowering of sealing capacity caused by thermal change in sealing of nozzle segments in a gas turbine by shaping two rails longitudinally in parallel on one side of a seal plate for making in touch with the end faces of segments elastically. CONSTITUTION:Two rails 6b and 6c are provided to be longitudinally in parallel on one side of a seal plate 6. In this construction, since gap flow passages between a seal plate main body 6a and grooves are bent due to the contraction of end walls 2' of segments in a cold state, a leak resistance is large to obtain a sealing effect for the time being. Meanwhile, in a hot state, the interval between segments are contracted, and their end faces 3' are brought in touch with rails 6b and 6c. Since rails 6b and 6c are circumferentially pushed to be elastically deformed, segments are free from a large thermal stress.

Abstract: PURPOSE:To perform a smooth vertical movement of a wick, by a method wherein the lower end of a wick-mounting plate is adapted to bend outward when the wick is lowered into a wick guide cylinder. CONSTITUTION:A wick 1 is attached, and parts 5 and 6, bent outward, are attached to the upper end and the lower end of a wick-mounting plate 4 whereto the wick 1 is vertically movable mounted.

Besides, the wick 1 is firmly adhered to the wick guiding outer cylinder 2 during combustion, and thereby the kerosene gasified in a fuel 14 is prevented from flowing in the combustion tube 13, resulting in ability to perform a perfect combustion in the set air-fuel ratio.

Title: Compression recording system for picture
Inventor: KOGA TOSHIO
IPC: H04N19/50
Filed: 1987-04-30
Abstract: PURPOSE:To realize not only normal rotation reproduction but also reverse rotation reproduction by allowing a picture signal between a head picture signal and an end picture signal to execute forcasting encoding which utilizes correlation between the picture units and allowing the head picture signal and the end picture signal to execute forcasting encoding which utilizes correlation within one picture unit. CONSTITUTION:When compressed picture data recorded on a CD-ROM 6 is read in the reverse order of recording, as the encoding within a frame G[E(n)'] is executed without a negative sign for a read (n)th frame at first, the same picture data V(n)' as a local encoding output obtained in the process of the encoding is reproduced. On the other hand, from forcasting error data E(n) successively sent after the forcasting data E(n)', the negative sign is added to the output of a reverse quantization circuit 13 and simultaneously to that, the encoding which utilizes the correlation between the frames is executed. Therefore the picture data V(n)'-E(n), that means V(N-1) is reproduced. Besides, the picture is reproduced in the reverse way when it is recorded such as V(n-2) is reproduced with V(n-1)-E(n-1) successively to the reproduced picture V(n-1) of a (n-1)th frame and finally all the picture data from V(n) to V(1) are reproduced.

When the corrosive state of the pipe 2 is to be monitored, sampling pipes 3, 4 are connected to the inlet and outlet of the pipe 2 and the increment of the concentration of Mn<2+> ions in a flowing fluid 1 is measured. The quantity (m) of corrosion in the whole pipe 2 and the corrosion speed (dm/dt) are found out from equations ( I ), (II) on the basis of said measured value. In these equations, V is the flow rate of the fluid in the pipe, DELTAx is the increment of the concentration of Mn<2+> ions, t is the stay time of the fluid in the pipe, s is the contacting area of the pipe with the fluid, and rho is the concentration (Wt%) of Mn in the pipe material. The concentration of Mn<2+> ions is obtained by measuring the fluid collected by the sampling pipes 3, 4 on the basis of direct absorptiometry.
