Disclosed is a beverage extraction filter that can extract in a plurality of extraction machine types. The beverage extraction filter comprises a filter unit (40) where coffee powder is housed and a planar lid unit (41) mounted to the top section of the filter unit (40). The lid unit (41) is formed in a layer structure created by a non-permeable first sheet member (42) positioned on the filter unit side (40) and a permeable second sheet member (43) layered on top of the first sheet member (42), and a hole section (42a) through which hot water is made to pass is formed in the center of the first sheet member (42).

Provided in the present invention is a catalyst for an ATR (autothermal reforming) process of hydrogen production, as well as the methods to prepare and use it. The catalyst comprises a precious metal of the platinum family (e.g., Pt, Pd, Ru, Rh, Ir) and combinations and mixtures thereof as the active component, an alkali metal oxide and/or alkaline metal oxide as the first additive, and a CeO2-based composite oxide as the second additive. The catalyst can be used in pellet form, or may be formed into a monolithic form with all the catalytic active components and additives loaded on a support with a regular structure, such as a ceramic honeycomb, a metal honeycomb, or a metal foam.

A current sensor that can reduce a measurement error due to isotropic elongation or strain owing to temperature and the like. A first half bridge circuit is placed in a first region divided by a center line of a mounting substrate, and a second half bridge circuit is placed in a second region, and the half bridge circuits are equally formed and placed point symmetrically about the central point of the mounting substrate. Even if elongation or strain occurs isotropically in the mounting substrate of magnetoresistive elements owing to temperature, the half bridge circuits undergo the influence of the elongation or strain equally as the bridge circuit. Thus, it can cancel the effect and reduce the measurement error due to the isotropic elongation or strain owing to temperature.

An electrical connector comprises a connector housing having a retainer receiving opening and a terminal insertion opening. A retainer is receivable in the retainer receiving opening and has a terminal receiving aperture that substantially aligns with the terminal insertion opening to form a terminal receiving path. The retainer is moveable between a first position and a second position. An elastic lance extends from a lower edge of and substantially beneath the terminal receiving aperture. A shoulder is formed on an upper surface of the terminal receiving aperture opposite from the elastic lance. An engaging claw extending from the elastic lance extends into the terminal receiving path in the first position for temporarily engaging a terminal, and the shoulder extends into the terminal engaging path in the second position for permanently engaging the terminal. The engaging claw is removed from the terminal receiving path in the second position.

An optical communication equipment comprises shared optical sources 88a–88d to be shared by communication nodes 100a–100d, the wavelengths of optical signals 76a–76d are converted into desired wavelengths λa–λd according to the addressed information of the corresponding optical label signals 77a–77d by using the shared optical sources 88a–88d, and routed to the addressed communication nodes without being converted into electrical signals by using the wavelength routing function of the cyclic-wavelength arrayed-waveguide grating (AWG) 120. The load of each communication node can be reduced by incorporating the multi-wavelength optical sources, which can be shared among individual communication nodes, into the router 80. Further, each communication node is provided with an optical gate or the like for returning the optical signal to the communication node from which the optical signal has been transmitted through the router 80 in order to adjust the transmission time lag between the optical signal and the corresponding optical label signal by the controllers 110a–110d.
