Abstract: A controller for a 3D observation apparatus performing 3D observation based on parallax using a plurality of optical systems includes the following sections. A start time acquisition section obtains a start time when energization of the 3D observation apparatus is started. An interrupted time acquisition section obtains an interrupted time when previous energization of the 3D observation apparatus is interrupted. A non-active time calculation section calculates a non-active time which is a period of time between the interrupted time and the start time. A determination section determines whether or not misalignment correction to correct misalignment of optical axes of the optical systems is necessary based on the non-active time.

Abstract: A buffer circuit includes a storage unit having a first storage capacity that stores data based on a write request inputted from an outside and outputs the data in an order in which the data was written, based on a read request inputted from the outside. And a second storage capacity in the first storage capacity which is used to store the data is adjusted based on an amount of valid data which has been written into the storage unit but has not been read from the storage unit.

Abstract: Method for manufacturing a plate boehmite and a plate alumina having high catalytic activity. The plate boehmite is prepared by subjecting at least one kind of an alkaline earth metal compound, which is selected from calcium, strontium and barium, and aluminum hydroxide to pressurization and heating at 150 to 300° C. in the presence of water. The resulting reaction product is treated with an acid to remove the residual alkaline earth metal compound contained in the product, followed by rinsing with water. The resulting plate boehmite is subjected to calcination at 450 to 1500° C. Thus, a plate alumina comprising a mixture of &thgr;-alumina and &dgr;-alumina as a major component is prepared.
