摘要： PROBLEM TO BE SOLVED: To provide a sludge scraper in which it can be prevented surely that algae adhere to a main chain and other metal-made constituent members, bacteria are generated on the algae and the main chain and the other metal-made constituent members are corroded.
SOLUTION: This sludge scraper is constituted so that the surface, in whole or in part, of each of the metal-made constituent members such as the main chain which are immersed in sewage is coated with a photocatalyst. As a result, since algae can be prevented from adhering to the metal-made constituent members, it can be prevented that the metal-made constituent members are corroded, the service life of each of them is shortened and they are made to look extremely unattractive by the generation of anaerobic bacteria.

摘要： PROBLEM TO BE SOLVED: To provide a control method for building structure which controls a passive type vibration control device with a nonlinear attenuation coefficient only by a mechanical mechanism.
SOLUTION: Hydraulic oil in a first oil chamber 9 is compressed and a reaction force is applied to a piston 5 while a force in the direction of D (opposite direction of direction A) is applied to the piston 5 of a hydraulic damper 1. Strain energy is stored in the hydraulic damper 1 during that time, and when the direction of vibration is reversed and a force in the direction of A is applied to the piston 5, an opening/closing valve 25 is opened and the pressure of the compressed hydraulic oil in the first hydraulic chamber 9 is released at a time to absorb the strain energy stored in the hydraulic damper 1.

摘要： PROBLEM TO BE SOLVED: To provide a tool holding member, wherein aging change due to using environments is rarely caused, and its manufacturing costs is significantly reduced. SOLUTION: This tool holding member 50 is provided with a tool holding hole 58 detachably supported by a movable supporting member 4 in a machine tool and exchangeably holding a tool 8 used at the time of an operation of the machine tool, to form a thermosetting resin material by injection molding. Since the thermosetting resin is used, the tool holding member is difficult to cause aging change due to its using environments. Compared to the tool holding member manufactured by a compression molding method using the thermosetting resin, a manufacturing time is shortened, so as to significantly reduce manufacturing costs of the tool holding member.
