摘要： A method for controlling the shrinkage of ceramic formed bodies is provided, including performing a preliminary test to determine an average shrinkage of ceramic formed bodies made from test lots of a ceramic powder, and determining a linear correlation between the average shrinkage and measured amounts of the ground test lots removed from a ball mill during a specific milling time interval. A batch of the ceramic powder is then ground, an amount of the ground ceramic powder removed from the ball mill during the specific time interval is measured, and the linear correlation is used to estimate the shrinkage of a ceramic body made therefrom. The difference between a target shrinkage and the estimated shrinkage is determined, and one or more of the processing conditions used to form the ceramic body are changed to offset the difference.

摘要： A fuel cell employs a stack structure in which a plurality of sheet bodies and a plurality of separators are stacked and joined together in alternating layers. Chemical reactions occur in the sheet bodies. The separators separate, from each other, two kinds of gasses (air and fuel gas) which are necessary for the chemical reactions. The plurality of separators consist of high-rigidity separator(s), and ordinary separators, which are lower in rigidity than the high-rigidity separator. This configuration reliably suppresses the occurrence of “separation of a joint region” attributable to “stress concentration caused by increase in the number of the stacked separators.

摘要： A solid oxide fuel cell has a stack structure in which sheet bodies and support members are stacked in alternating layers. A space through which a fuel gas or air flows is formed between the adjacent sheet body and support member. Partitions are provided on the support member in such a manner as to stand in the space, thereby forming a “first flow F1” of gas according to the flow control effected by the partitions. Gaps are formed at the projecting ends of the partitions, thereby forming a “second flow F2” of gas which flows over the partitions and through the gaps. The ratio “gap/space height” is set to 2% to 50% inclusive.

摘要： One image is displayed in a period as one frame, which includes one charge accumulation period and one light emission period. In the charge accumulation period, all electron emitters are scanned, and voltages depending on the luminance levels of corresponding pixels are applied to the electron emitters which correspond to pixels to be turned on (to emit light), to accumulate charges (electrons) in amounts depending on the luminance levels of corresponding pixels in the electron emitters which correspond to pixels to be turned on. In the next light emission period, a constant voltage is applied to all the electron emitters to emit electrons in amounts depending on the luminance levels of corresponding pixels from the electron emitters which correspond to pixels to be turned on, thereby emitting light from the pixels to be turned on.

摘要： A thin plate member 10 has a uniform thickness of not less than 5 μm and not more than 100 μm, includes at least a ceramic sheet, and is formed by sintering. The thin plate member 10 has plural convex portions 11 protruding from one plane P of the thin plate member 10, and plural concave portions 12 caved in from the plane P. Accordingly, the deflection amount obtained when the thin plate member 10 is supported at a predetermined support section of the thin plate member 10 and a load is applied to a load applying section, which is other than the support section, of the thin plate member 10 in a direction orthogonal to the plane P is smaller than the deflection amount of a thin plate member that is flat without having the convex portion 11 and the concave portion 12. That is, the thin plate member 10 which is difficult to be deformed can be provided.

摘要： An electron emitter includes an emitter section having a plate shape, a cathode electrode formed on a front surface of the emitter section, and an anode electrode formed on a back surface of the emitter section. A gap is formed between an outer peripheral portion of the cathode electrode and the front surface of the emitter section. The front surface of the emitter section contacts a lower surface of the outer peripheral portion to form a base end as a triple junction. The gap expands from the base end toward a tip end of the outer peripheral portion.
