摘要:
The present invention relates to a technique wherein a complex structure is adopted as a joint structure between each head of plural piles (1) and a bottom of a footing (2), and the complex structure may be selected among either a complex of a roller bearing structure (Y) interposing a sliding member (12) and a pin bearing structure (X) interposing a sliding member (32), another complex of a rigid joint structure (Z) and the roller bearing structure (Y), or still another complex of the rigid joint structure (Z) and a pin bearing structure (X). This can restrain the rotation of an upper structure (A), reduce stress concentration applied to a joint portion and occurrence of a bending moment on the pile (1) in applying a great external force such as an earthquake thereto, prevent damages or destroys of the joint portion and the pile, and also enhance excellent positional restoration performance for restoring the upper structure (A) to an initial position thereof, after the earthquake happens.

The optical recording device including a reading head (11) and a reading laser (7) for encoding optical data (3) on a CD (1) as two dimensional (i.e. pit length and pit depths (13, 15)) optical data (3) along a spiral track, one of the data streams may be used to implement a hologram on the data recording surface, the preferred form of the invention uses a uniform pit depth within each pit, causing pit depth to vary only from pit to pit and not within a single pit, the second data stream relies on the primary data stream for much of the necessary error correction required in dense data transmission media.

The invention relates to an arrangement of a gas decompression turbine (1) in a gas supply line system. The invention provides for an asynchronous motor (3) or asynchronous generator to be positioned in a section (2) of a gas supply line on the incoming (high-pressure) side of a radially arranged separating wall (5) fitted with nozzles (4) for decompressing the gas. At least one bucket wheel (7) of light-weight construction and driven by the gas current is mounted on the shaft (6) on the outflow (low-pressure) side behind the nozzles (4). The invention provides for devices for absorbing the electrical energy generated by the generator of the asynchronous motor (3) and for feeding said energy into an energy supply network. It further provides for a control device (9) which sends a control signal to a safety valve (10) positioned on the incoming side in front of the asynchronous motor/generator for (partially) closing the section of gas supply line when the shaft (6) exceeds a critical number of rpms.

The present invention relates to a modified crumb rubber particle having carbon to silicon bonds created by the reaction of the unsaturation in the crumb rubber particle and silicon hydride, with or without the use of a catalyst. Bound silicon content ranges from about 0.1% to 10% by weight. The silicon-modified crumb rubber can be used as is or a reinforcing filler in formulations. Typically the silicon-modified crumb rubber is used in up to 25% by weight of the total rubber present in virgin rubber compositions.

An assembly (100, 400) for a magnetocaloric refrigeration unit includes a magnetocaloric core (102, 402). Electromagnetic coils (104, 406) may be wound around the magnetocaloric core (102, 402). The assembly (100, 400) further includes one or more cooling structures (1608) to extract the waste heat generated from the electromagnet coils (104, 406). In some embodiments, the assembly may include one or more magnetic yokes (106, 408) disposed at the longitudinal ends of the magnetocaloric core (102, 402). At least one of the top surface and the bottom surface of the magnetic yoke (106, 408) is provided with a micro-channel structure (202). In other embodiments, the assembly may include a coil housing (108, 410) disposed around the electromagnet coil (104, 406). The coil (108, 410) housing includes cooling structures (1608) such as, but not limited to, a microchannel structure, a fm structure, and a heat pipe structure.
摘要:
A test strip and a detecting device are disclosed. The test strip can be used with an electrochemical instrument to accurately detect the viscosity and concentration of an analyte of a specimen. The test strip includes a first specimen path, a first electrode set, a redox reagent, a second specimen path, a second electrode set, and a reaction reagent. The redox reagent includes at least a redox pair. When the specimen enters the first specimen path, the redox pair dissolves and generates an electrochemical redox reaction for obtaining a flow time of the specimen. When the specimen enters the second specimen path, the reaction reagent is used to obtain the analyte concentration of the specimen, and the concentration of the analyte can be corrected by the flow time.
摘要:
An electronically controlled fuel injection valve can control the time to inject fuel and the amount of fuel to be injected in response to a control signal independently from the operating condition of an engine unlike a traditional mechanical fuel injection valve. The electronically controlled fuel injection valve employs a control method for fuel injection that increases the force of lifting up a cutoff needle of an injection controller by delivering high-pressure fuel to a lower pressure chamber via a control needle, thereby rapidly controlling fuel injection, has a simple structure making it easy to assemble, replace and precisely machine parts, and has a simple flow path structure which facilitates fabrication.
