A recycling method comprises classifying products to be recycled on the basis of classifier unit information, decomposing and fractionating some of the products on the basis of fractionator unit information. Applying a physical action to the fractionated products on the basis of physical action information. Producing a recycled material on the basis of recycled material producer unit information. Producing a recycled component from the recycled materials on the basis of recycled component produc...

A memory cell in a so-called MRAM by utilizing a tunnel magnetic resistance in the prior art has raised problems that a magnetic field to be applied to a TMR element is essentially weak since a word line for write is disposed apart from the TMR element, that a large current is required at the time of a writing operation, and that electric power consumption is large. In order to solve the above-described problems experienced in the prior art, the present invention provides an MRAM memory cell str...

A system for the detection of a pressure drop in a tire comprising a tire air pressure sensor, a tire temperature sensor and an evaluating unit. The evaluating unit converts the measured air pressure values and temperature values into temperature compensated air pressure values and produces an alarm signal when the temporal fluctuation exceeds an air pressure fluctuation threshold value. The evaluating unit decreases the air pressure threshold value with increasing deviation from the measured te...

An image-taking apparatus capable of mounting an accessory, which is small-sized yet capable of securing a sufficient inner volume is disclosed. The image-taking apparatus includes a first member having a female screw hole portion into which a male screw portion provided in the accessory is inserted, a main chassis to which the first member is fixed and a second member which covers an opening of the female screw hole portion opposite to the insertion side of the male screw portion. The female sc...

A paint roller assembly has a lower frame and an upper frame. A spring connection assembly connects the upper frame to the lower frame to permit the upper frame structure to pivot or flex with respect to the lower frame. The upper frame and the lower frame are each constructed and arranged to receive a cylindrical paint roller support for holding paint rollers. A handle member on the lower frame is used by the workperson to operate the paint roller assembly.

A road test simulator having four rollers, each provided with an uneven surface coating, and four asynchronous motors, each of which drives one of the rollers.

A wheel holder assembly includes a mounting frame fixedly fastened to the footplate of a skateboard, a screw bolt mounted in the mounting frame, a hook plate mounted on the screw bolt and hooked on a barrel at the mounting frame, a swivel wheel holder frame mounted on the screw bolt to hold a pair of wheels, a first corrugated washer and a second corrugated washer mounted on said screw bolt and matched with each other between the hook plate and the wheel holder frame, the first corrugated washer...

Disclosed is an optical-fiber preform having barrier layers to hydroxyl radicals, the optical-fiber preform comprising: a quartz tube in the form of a cylinder shape serving as a substrate for forming the optical-fiber preform; a first barrier layer for preventing hydroxyl radicals from permeating the optical-fiber preform and deposited onto the inner surface of the quartz tube; a second barrier layer having a permeation coefficient higher than the first barrier layer and deposited onto the firs...

The invention relates to a method for producing high purity 1,2-dichloroethane using a liquid reaction medium that is circulated and that is essentially composed of 1,2-dichloroethane and a catalyst. At least ethylene and chlorine are added to the reaction medium and a mainly chlorine-containing gas flow is dissolved in a part of the reaction medium which is essentially devoid of dissolved ethylene. The gaseous components not dissolved in this solution are removed from the solution by means of a...

An apparatus for securing the internal rotational components of a disk drive utilizes an annular clamp retention device. The clamp retention device has a rigid, metallic, main ring body from which protrudes a plurality of compliant tabs having a generally L-shaped cross-section. The compliant tabs extend radially inward from the body to form an inner circular array of the tabs. In addition, a plurality of rigid planar flanges, which are larger than the compliant tabs, extend radially outward fro...
