摘要:
A method of manufacture an ink jet head in which an ink is jetted from a nozzle hole by applying an electric voltage to an electrode so as to deform ink chambers divided by a partition wall. The method includes the steps of providing plural piezoelectric base plates having polarization side by side on a first non-piezoelectric plate, forming plural grooves for the ink chambers on the piezoelectric base plates and at connecting portions where each edge of the plural piezoelectric base plates provided side by side comes to face other edge; and mounting a second non-piezoelectric base plate on the plural piezoelectric base plates as so to cover the plural grooves so that the ink chambers divided by the partition wall are formed.
摘要:
A supporting device to support a magnetic head in close proximity to a photographic film passage so that the track section of the magnetic head is brought in contact with a magnetic layer on the film, includes a supporting member, a fixing member on which the magnetic head is fixed, two supporting resilient arms one ends of which are fixed to the fixing member and the other ends are fixed to the supporting member. The two supporting arms are fixed in such manner that the two supporting arms are inclined relative to a surface of the fixing member and imaginary lines which are colinear with and extend from the two first supporting arms cross each other at an imaginary line which is colinear with and extends from a magnetic gap of the track section of the magnetic head.
摘要:
There is disclosed an analytical element which comprises a support and a reagent layer comprising a peroxidative substance, a diffusion-resistant phenol compound, and an aromatic primary amine compound or its salt which brings about a coupling reaction with said diffusion-resistant phenol compound when oxidized, to thereby produce a dyestuff.
摘要:
There is disclosed an analytical element comprising a light-transmissive and liquid-impermeable support and at least one developing layer of a fibrous structure containing at least one kind of interactive composition reactive with a component in a liquid sample, characterized in that the fiber constituting the developing layer of a fibrous structure and the interactive composition are bonded to each other by a compound having a reactive group. A quantitative analysis of a specific component in a liquid sample can effectively be carried out by using the analytical element according to this invention.
