Patent JP-S60221706-A (JP)
Title: Optical fiber
Inventor: TANAKA KATSUKI
IPC: G02B6/036
Filed: 1985-03-29
Abstract: PURPOSE:To decrease a coefficient of mode coupling and to prevent electric power from being diffused by providing an annular multimode core part to the outer peripheral part of a single-mode core as a center part. CONSTITUTION:The single mode transmission line consists of the single-mode core part 1 and an intermediate clad part 5 and a multimode transmission line consists of an annular multimode clad part 5 and an external clad part 3. This structure makes the electromagnetic field distribution of light of the single-mode transmission line greatly different from that of the annular multimode transmission line, so mode switching between the both is hard to occur and the diffusion of photoelectric power from a single mode area to a multimode area is suppressed low.

Title: Preparation of carrier for microbe
IPC: B01D53/81
Filed: 1992-03-19
Abstract: PURPOSE:To prepare a carrier to support microbe which is suitable for microbe to inhabit and has high sewage or malodor treatment efficiency by using an economical material prepared by hardening a raw material which contains fluidized bed boiler ashes discharged out of a fluidized bed boiler as a main component by adding water to it. CONSTITUTION:A carrier to support microbe is used for waste water treatment or an malodor treatment apparatus using the work of microbe. In this case the carrier to support microbe is prepared by hardening a raw material which contains fluidized bed boiler ashes discharged out of a fluidized bed boiler as a main component by adding water to it. As the fluidized bed boiler ashes, ashes containing 10-50wt.% of calcium soluble in water as unslaked lime are used. Also, the fluidized bed boiler ashes are hardened after being finely pulverized. Further the unslaked lime is hardened after being slaked to convert into slaked lime. Meanwhile, after the raw material containing the fluidized bed boiler ashes as a main component is hardened, aging by steam is carried out. In this way, using an economical material, a carrier to support microve which is suitable for microbe to inhabit is obtained.

Title: Vacuum pump
Inventor: NAKAMORI KAZUAKI
IPC: F04D29/10
Filed: 1989-03-17
Abstract: PURPOSE:To prevent reaction product in sucked gas from being stack to flow passage sections by providing shaft-seal gas feed holes in a space between a pump casting and a stator, providing shaft-seal gas passages inside the wall of the stator, and giving heat from a pump mechanism section to the sucked gas. CONSTITUTION:A shaft-seal gas feed port 19 is provided on a pump casing 1, and feed gas is supplied to a space 20 formed between the pump casing 1 and the stator 6 of a pump mechanism section 5. Gas feed holes 21 and 22 and gas passages 23 and 24 are provided in the stator 6, and the shaft-seal gas in the space 20 is forced to flow into a shaft-seal section 8 through the inside of the wall of the stator 6. Accordingly, the shaft-seal gas fed to the space 20 is heated by exchanging heat with the outer wall surface of the stator 6, and heated further in the gas passages 23 and 24. Thus, the atmosphere air sucked from a suction port 2 receives heat near delivery ports 3 and 4 and, even if it contains reaction product, the product does not transform into a solid so as to prevent the reaction product from being stuck to the wall surfaces of the flow passage sections.

Title: Device and method for storing data
Inventor: TAKAGI SHIRO
IPC: G06F3/06
Filed: 1995-03-23
Abstract: PURPOSE: To reduce the number of times of access by reading compressed data corresponding to a designated physical block number while extending those data when storage in a memory is judged but reading data for the block unit of a logical block number when storage in a physical block is judged. CONSTITUTION: It is discriminated while using a logical block managing table whether the block data of the logical block number designated by a host processor are stored in a compressed data storage part or in a physical block storage part. When those data are recorded in the compressed data storage part, the read data are extended but when those data are stored in the physical block storage part, those data are read out as they are. Thus, the number of times of access to the physical block storage part is decreased and the access to the data storage device can be accelerated. Further, since the compressed data storage part stores data in a small compression size, storage capacity can be reduced.

Title: Gas sealing method for electric resistance weld steel pipe weld zone
Inventor: NOGUCHI TAKAO
IPC: B23K13/06
Filed: 1989-03-16
Abstract: PURPOSE:To eliminate the need for a gas sealing cover by injecting inert gas by an injection nozzle arranged to the inside of a electric resistance weld steel pipe, specifying the ratio of flow velocity of an inner cylinder to that of an outer cylinder to inject the inert gas by a double cylindrical nozzle arranged to the outside of the electric resistance weld steel pipe. CONSTITUTION:Butt parts 3 and 3 of a blank pipe 2 are subjected to induction heating at electrode contact points 4 and 4 by high-frequency electrodes and pressed by side rolls 5 to form the electric resistance weld steel pipe 1. Piping 7 of nitrogen gas is inserted into the inside of the blank pipe 2 in the direction of the side rolls from the front of the side rolls 5 to inject the nitrogen gas. In addition, the nitrogen gas is injected toward the electrode contact points from the coaxial double cylindrical nozzle 10 of the tip of piping 9 above the blank pipe 2. The flow velocity of the inert gas flowing through the inside 12 of the inner cylinder 11 is made faster than that of gas flowing through space 14. Further, a straightening vane 15 is provided to the inside 12 of the inner cylinder 11 to prevent the turbulent flow of the inert gas. The flow velocity distribution where the flow velocity is delayed toward the outside from the center is formed on the nozzle 10. By this method, contamination of oxide inclusion on a weld zone is prevented without using the sealing cover.

Filed: 1987-03-19
Abstract: PURPOSE:To inform the occurrence of a prescribed error when a pseudo key is pushed by actuating an error occurrence informing means to inform the occurrence of an error when a key is not normally detected. CONSTITUTION:When a key A is turned on at a time point t6, a code generating means 6 produces a code to the key A. When a key C is turned on at a time point t7, the output of an AND circuit 14 varies to prevent the occurrence of a new code. Then, a released key checking means 5 checks a released key by the output of a voltage deciding circuit 4 when the key C is turned off at a time point t8. In this case, the means 5 drives an error occurrence informing means 7 to produce an error signal owing to a fact that the key releasing order is reversed after knowing that the key C that produced no code yet is turned off.
