Title: Volute casing
Inventor: TANAKA TEIJI
IPC: F04D29/44
Filed: 1990-01-17
Abstract: PURPOSE:To reduce radial thrust and friction loss of a flow passage by arranging tongues and partition walls constituting a volute at equal intervals on the circumference, positioning the end of a partition wall up to the beginning of a succeeding tongue, and specifying the area ratio of an inside flow passage to an outside flow passage partitioned with the terminal end of a partition wall. CONSTITUTION:A volute casing 201 is provided with (n) over three pieces of tongues 202 equally arranged on the circumference, and respective tongues become partition walls 203 while enlarging the radial positions in the circumferential direction. The partition wall 203 is ended on the position in the circumferential direction from which the succeeding tongue 202 is begun, and the area ratio the inside flow passage 205 to the outside flow passage 206 is instituted nearly as 1:n-1, which are formed on the overlapped part 204 between the terminal end of the partition wall begun fro the (n-1)th tongue and the (n)th tongue 202. By action of the tongue and the partition wall symmetrically positioned, static pressure distribution is made symmetrical against the rotating shaft and hence radial thrust can be reduced. Further, friction loss can be reduced, because the outside flow passage 206 for guiding the fluid flowing along the tongue to a discharge pipe 207 is widened on the lower stream side.

Title: Wavelength split type optical channel
Inventor: WATANABE ATSUSHI
IPC: H04B10/27
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability against a failure by adopting a redundancy configuration where no switch back from a standby system to an active system is required when a fault is recovered and to allow the channel to have provision for increase/decrease in input output transmission channels flexibly by using a confluent switch for the switching. SOLUTION: (N+H) sets of optical distributers 21, (N+H) sets of confluent switches 31 that distribute signal lights into N directions depending on the wavelength bands and (N+H) sets of optical combiners 41 are connected to N input optical transmission lines 11 via an optical spatial switch 61 providing outputs of (N+H) so as to provide H-sets of standby systems. When any of the confluent switches 31 is faulty, the setting of the optical spatial switch 61 is changed to select any of the H sets of the standby system to avoid the failure and no switch back after restoration is conducted to avoid interruption of communication.  Since the confluent switches 31 are dependent on the circuit scale and number of optical transmission lines, the required minimum configuration is enough to cope with the increase/decrease in the input output optical transmission line number N, and the extension performance with respect to the increase in traffic is enhanced.

Title: Accumulator that utilizes compressibility of fluid
Inventor: SUGIMURA NOBUYUKI
IPC: F16L55/04
Filed: 1990-01-16
Abstract: PURPOSE:To expand the range of working pressure of an accumulator to infinity and prevent the damage of a separating member by partitioning the inside of a main body to a fluid chamber and a sealed fluid chamber with the separating member, and sealing fluid in the sealed fluid chamber. CONSTITUTION:When the pressure of fluid A of a fluid pressure circuit varies, the fluid A pushes a bladder 2 while making its entrance and exit through a communicating pore 5. Since sealed fluid 10 is compressed then, the bladder 2 is deformed as well as the pulsation suction of the fluid pressure circuit, etc., is performed. At this time, the deformation of the bladder 2 is small against high compression fluctuation as the sealed fluid 10 has smaller compressibility compared with gas, and the temperature of the inside of a sealed fluid chamber does not become high too. Therefore, damage of the bladder due to carbonization damage and flexure fatigue, etc., does not occur.

Filed: 1985-01-18
Abstract: PURPOSE:To eliminate warp of a wafer by attaching such material as less thermal expansion coefficient than the wafer in the form of film with sputtering method on a face polished previously and polishing the other side of the wafer thereafter. CONSTITUTION:One side of a wafer is polished and material having less thermal expansion coefficient than that of the wafer is attached in the form of film to the polished face 15 with a vacuum evaporation method or sputtering method. This time, temperature of a substrate becomes a hundred and some tens degrees. Then, the substrate fit by thin film 20 thereon at this temperature is to generate stress due to the difference in expansion coefficient between the film 20 and the substrate when changing to normal temperature. By using the stress, warp deltaof the wafer is absorbed. After such a processing, the other side 14 of the wafer is polished, then parallelism of the surface to back face can be kept, and efficient parallel polishing can be made.
