摘要:
On each of upper and lower surfaces of a flat-plate-like support substrate having a longitudinal direction and having fuel gas flow channels formed therein, a plurality of power-generating elements A connected electrically in series are disposed at predetermined intervals along the longitudinal direction. On each of the upper and lower surfaces of the support substrate, a plurality of recesses are formed at predetermined intervals along the longitudinal direction. Each of the recesses is a rectangular-parallelepiped-like depression defined by four side walls arranged in a circumferentially closed manner and a bottom wall. That is, in the support substrate, frames are formed to surround the respective recesses. Fuel electrodes of the power-generating elements A are embedded in the respective recesses, and inter connectors are embedded in respective recesses formed on the outer surfaces of the fuel electrodes.

A second mold is placed on a planar surface of a first mold to form a first mold cavity, which is filled with a first material slurry containing a first material powder and the molded slurry is caused to set, thereby forming a first molded part on the planar surface of the first mold. A third mold is placed on the planar surface of the first mold from which the second mold is removed and on which the first molded part is formed, thereby forming a second mold cavity. The second mold cavity is filled with a second material slurry which contains a second material powder different from the first material powder so as to mold the slurry in contact with the first molded part. The molded slurry is caused to set, thereby forming a second molded part on the planar surface of the first mold.

There is realized a piezoelectric/electrostrictive device of a laminated type from which a large displacement is obtained and which is highly reliable over a long period. A laminated piezoelectric/electrostrictive device 1 has: a laminated columnar article 10 constituted by alternately laminating a plurality of piezoelectric/electrostrictive layers 14 and inner electrode layers 18, 19; and a pair of outer electrodes 28, 29 disposed on a peripheral surface of the laminated columnar article 10 to connect layers having the same polarity to each other among the inner electrode layers 18, 19. This laminated piezoelectric/electrostrictive device 1 is characterized in that interfaces 2a, 2b having a relatively low interface strength as compared with the other interfaces are disposed at a specific interval among the interfaces between layers of the laminated columnar article 10.

A fluid observation apparatus 20 can perform a method for observing a fluid by PIV. The method for observing a fluid includes capturing an image of inorganic particles in a fluid for flow observation 30 by irradiating the fluid for flow observation 30 passing through a flow channel with light, the fluid for flow observation 30 containing inorganic particles to be observed each having a planar surface, a dispersion medium to be observed, and a viscosity modifier. The fluid for flow observation 30 is high-viscosity non-Newtonian slurry containing inorganic particles. The fluid for flow observation 30 may be a simulated fluid for a fluid for flow analysis. The simulated fluid closely resembles the particle size of inorganic particles to be analyzed and the viscosity of the fluid for flow analysis. The fluid for flow analysis contains the inorganic particles to be analyzed and a dispersion medium to be analyzed.

A passage detection apparatus is configured to detect the change in the properties (propagation state of sound wave, dielectric constant, etc.) of a specific space, which changes according to the passage of an object in the specific space and the size of the object. The passage detection apparatus includes a pair of detection units and configured to transmit and receive signals to and from an external device. The specific space is formed by the space between the detection unit and the detection unit. The detection unit is supported by a first substrate. The detection unit is supported by a second substrate that is parallel to the first substrate, and arranged at the position corresponding to the detection unit supported by the first substrate.
摘要:
A lower electrode 4 and an auxiliary electrode 8, a piezoelectric/electrostrictive film 5, and an upper electrode 6 are sequentially arranged in layers on a substrate 1. The lower electrode 4 is continuously formed in a region ranging from a first portion of the thick-walled portion 2 to a thin-walled diaphragm portion 3. The auxiliary electrode 8 is continuously formed in a region ranging from a second portion of the thick-walled portion 2 opposite the first portion to a position on the thin-walled diaphragm portion 3, the position being separated from the lower electrode 4. The upper electrode 6 is formed in such a manner as to overlie the piezoelectric/electrostrictive film 5 and the auxiliary electrode 8. Furthermore, a connection electrode 20 is provided for electrically connecting the upper electrode 6 and the auxiliary electrode 8. Thus, a plurality of paths are provided for electrically connecting the upper electrode 6 and the auxiliary electrode 8. Therefore, even when connection through a certain path is cut off due to fracture of a portion of the upper electrode 6 caused by deterioration in insulating performance of the piezoelectric/electrostrictive film 5, electrical connection between the upper electrode 6 and the auxiliary electrode 8 can be maintained through the remaining path(s).
摘要:
A gripping jig for assembling applies a force to a molded body in a direction perpendicular to an assembling direction. When an assembling load is applied to the molded body, the force is adjustable with an adjustment screw such that the molded body is guided to move in the assembling direction. Since the force is applied from a direction different from the assembling direction, the molded body can move in the assembling direction, and as the force is adjustable, application of the assembling load to the molded body and the movement of the molded body can be adjusted. Since a plurality of the molded bodies are fixed and assembled respectively, when there are variations in size of the molded bodies, if an excessive assembling load is applied, each molded body is guided to move, so that more uniform assembling load is applied to the plurality of molded bodies.

摘要:
In the assembly-completed state, the Lower Mold, the Outer Mold, the Upper Mold, and the “inner mold (the integral body of the Pin-holder and the Pin)” are stacked and fixed in this order from the bottom, and the Pin is coaxially inserted into the First Hole of the Outer Mold and the Second Hole of the Upper Mold. In the assembly-completed state, the molding space for molding the ceramic molded body is formed between the surface of the Pin and the First Hole, and the annular minute gap is formed between the surface of the Pin and the Second Hole. The ceramic slurry poured into the Slurry Reservoir Pres formed on the upper surface of the Upper Mold falls and flows into the molding space through the annular minute gap by virtue of the action of gravity or the like.
摘要:
The present invention provides a ceramic green sheet with a thin flat plate shape obtained by molding and solidifying a ceramic slurry, which contains a ceramic powder, dispersion medium, and gelling agent, into a thin flat plate. The ceramic green sheet partially includes a body that is obtained by molding and solidifying a conductor paste, which becomes a conductor later, and the body is exposed on a part of each of the both surfaces of the sheet. Plural ceramic green sheets described above are produced. The plural ceramic green sheets are successively stacked and press-bonded in the thickness direction in such a manner that the bodies included in the respective sheets are connected to each other for all combinations of the adjacent two sheets. As a result, a ceramic green sheet laminate is formed, which includes one body that is obtained by connecting the bodies included in the respective sheets.
