Testing microreactor, testing device and testing method

A fuel cell device has a small and compact structure as a whole. The fuel cell device employs a fuel cell (e.g., direct methanol fuel cell of an MEA structure) using liquid fuel. Diluted liquid fuel is prepared by diluting the liquid fuel (methanol-contained liquid in the case of DMFC) with dilution liquid, and is supplied to the fuel cell. A first pump unit stacked on the fuel cell supplies the diluted liquid fuel to the fuel cell while diluting the liquid fuel by mixing the liquid fuel and the dilution liquid together. A second pump unit stacked on the fuel cell collects liquid (water usable as dilution liquid in DMFC) produced by an electrochemical reaction in the fuel cell.

Display panel and method of producing the same

An inkjet printing head which is capable of being assembled efficiently and easily. In the inkjet printing head, a main frame has a hollow portion for receiving a flexible cable therein, and a sub-frame has a rimmed window for receiving a flexible member. The main frame and sub-frame are combined such that the flexible cable and flexible member are sandwiched therebetween. The hollow portion of the main frame, the flexible cable and the rimmed window of the sub-frame have the same shape so that these members can be reliably positioned with respect to one another. Electrodes on the flexible cable are pressed, with a uniform pressure, to piezoelectric elements of a head assembly attached to the main frame.

An ink jet print head can be formed by an anodic bonding process. In order to bond a vibrating plate to a head base, a glass surface is bonded to a conductive surface of an electrically conductive material through anodic bonding. One of the vibrating plate or the head base can be formed of glass and the other of an electrically conductive material in order to form the bond. Alternatively, a glass layer an electrically conductive layer can be formed on each of the pieces, which can then be bonded. Thus, by using appropriate layers, the head base and vibrating plate can be formed of plastic, glass or an electrically conductive material.

An ink jet printing head which both realizes a higher density and prevents a failure in ink jetting and deterioration in the printing quality. A photosensitive glass substrate which allows anisotropic etching is provided with a multiplicity of individual ink passages each having a narrow width and a large depth formed in an array by anisotropic etching in such a manner that each extends from the rear end of the glass substrate to the forward end thereof. A diaphragm is attached to the surface of the glass plate on which the individual ink passages are formed in such a manner as to cover all the individual ink passages. A common electrode is provided on the diaphragm, and individual piezoelectric elements are fixed to the common electrode at the portions corresponding to the individual ink passages. Individual electrodes are provided on the respective individual piezoelectric elements. When a voltage is applied to the common electrode and the individual electrode, the portion of the diaphragm corresponding to the individual electrode is bent and deformed, so that the ink storing capacity of the corresponding individual ink passage is reduced and some of the ink in the individual ink passage is forced out.
