In a fuel vapor processing system, a float valve and a check valve are provided in upper parts of a fuel tank to conduct fuel vapor to a canister via a fuel vapor passage. The check valve includes a low set-pressure valve and high set-pressure valve, and operates in two stages so that the internal pressure of the fuel tank can be favorably controlled by the opening of the low set-pressure valve when the fuel tank is being filled to full so that the sensor associated with the fill nozzle can successfully detect a tank full state, and any excessive rise in the internal pressure of the fuel tank typically caused by a high temperature of the surrounding environment can be avoided by the opening of the high set-pressure valve.

An adjustable kettlebell or exercise device includes a handle device formed on a receptacle, and one or more weight members selectively engageable into the receptacle, and a control device includes a shaft engaged through the receptacle and engageable through the weight members for selectively anchoring either of the weight members to the receptacle with the shaft. The weight members each include a bore for engaging with the shaft, and an opening communicating with the bore of the weight members, and the shaft includes one or more pins engageable through the openings of the weight members for selectively engaging with the weight members.

Improvements in the compactness and performance of integrated circuit devices are gained through the fabrication of vertical transistors for which channel sizes are determined by the accuracy of etch techniques rather than the resolution of photolithographic techniques. A method of fabricating an integrated circuit includes forming a plurality of doped layers in a series of depths in a substrate wafer, and etching a trench in the substrate wafer. The trench extends through the doped layers at a plurality of depths and is bounded by vertical sidewalls and a planar horizontal floor. The method further includes forming a conductive sidewall spacer adjacent to the vertical sidewalls of the trench.

A processing apparatus is used for processing a workpiece such as a semiconductor wafer. The processing apparatus comprises a cover for covering a portion of a surface, to be processed, of a workpiece, a process chamber formed by the cover and the surface, to be processed, of the workpiece, and a sealing portion provided between the cover and the surface of the workpiece for sealing the process chamber.

An adjustable barbell or dumbbell or exercise device includes a handle device having a handle bar engageable into grooves of a number of weight members, a number of plates disposed on the handle bar and each having an engaging element for engaging with tongues of the weight members when the plates and the hand grip are rotated relative to the handle bar, and for anchoring a selected number of weight members to the handle bar with the plates, and a detecting device includes a displayer electrically connected to a central processing unit for displaying an information, and a switching device includes one or more weight detecting switch elements electrically connected to the central processing unit for sending signals to the central processing unit.

The invention discloses a high temperature-resistant methanation catalyst preparation method. The preparation method comprises preparing a catalyst semi-finished product with composite functions from nickel as an active component, a rare earth metal as a cocatalyst, and alkaline earth metal and alkali metal as anti-carbon formation components by a precipitation method, adding kaliophilite, graphite and pure calcium aluminate cement into the catalyst semi-finished product, carrying out mixing to obtain a uniform mixture, carrying out granulation and tabletting molding, and carrying out steam curing to obtain the catalyst finished product. The high temperature-resistant methanation catalyst retains good methanation activity in a use temperature range of 300-700 DEG C and has good thermostability and anti-carbon formation performances.

Product cabinet having an illumination element, wherein the illumination element is fastened to the product cabinet and further comprises:

a light-conducting luminous body which has a planar front side from which light emerges and which has a side surface into which light is fed, wherein the luminous body is configured so that the light entering laterally is deflected within the luminous body to the front side, so that it emerges there; and at least one light source, which emits light onto the side surface.

For optically measuring black carbon in the atmosphere an aerosol particle collection area of a filter tape is continually illuminated by an illumination source with light of one or more wavelengths. Transmitted and reflected light fractions are measured at several precisely defined angles or angle ranges, such as of 0°, 12° to 140° and 165 to 180° by means of photodetectors arranged correspondingly relative to the illumination source, achieving maximum symmetry for the angles to be measured. The loading of the filter tape collection area with light absorbing aerosol material is continually determined from the change in the optical properties of the collection area with the aid of known algorithms from transmissivities and reflectivities as detected.

In an intake system for an engine incorporated with a resonance chamber (32), a variable communication unit (50) for controlling the communication between an intake passage with the resonance chamber comprises an outer tube (51) having an open axial end (51a) and an opening (51b) defined in a circumferential wall thereof for communication with the resonance chamber and an inner tube (52) rotatably and coaxially received in the outer tube, the inner tube being provided with a communication inlet port (52a) at an axial end on a same side as the axial end of the outer tube and an opening (52b) in a circumferential wall thereof for defining a communication outlet port (50a) jointly with the opening in the outer circumferential wall of the outer tube. The openings of the inner tube and outer tube are configured such that at least one of a distance (L) between the inlet and outlet ports of the communication passage and an opening area (S) of the communication outlet port changes in relation with a relative rotational angle between the inner tube and outer tube. Thereby, the intake system can be formed as a highly compact unit and requires little power to operate.
