Title: Purification of alkoxide
Inventor: MATSUMURA TERUICHIRO
IPC: C07C29/68
Filed: 1988-07-22
Abstract: PURPOSE:To obtain a high-purity alkoxide simply and surely by reacting an alkoxide with a carbon dioxide gas in a solvent to convert the alkoxide into an organic carbonate, separating the organic carbonate from the reaction product and subjecting the organic carbonate to removal treatment of carbon dioxide gas to reconvert the organic carbonate to the alkoxide. CONSTITUTION:(a) An alkoxide is suspended in a liquid substantially not to dissolve the compound or (b) the alkoxide is dissolved in a solvent, the suspension or the solution is reacted with a carbon dioxide gas and converted into a solvent-soluble organic carbonate in the case of (a) or a solvent-insoluble organic carbonate in the case of (b). Then the solvent-soluble or solvent-insoluble organic carbonate is separated from the reaction product. The organic carbonate is dispersed in a liquid in the case of (b), the solvent-soluble or the solvent- insoluble organic carbonate is subjected to removal treatment of carbon dioxide gas so that the organic carbonate is decomposed and reconverted into the alkoxide to advantageously give high-purity alkoxide useful as a superconducting raw material.

Title: Light beam scanning optical device
Inventor: ONO OSAMU
IPC: G02B26/10
Filed: 1994-08-04
Abstract: PURPOSE:To prevent the accuracy of a scanning lens from being deteriorated and to make the angle of the polarizing area of a light beam small so as to restrain the increase of jitter by providing a rib whose incident side and outgoing side are flat adjacently to the image scanning area of the scanning lens and receiving the light beam transmitted through the rib by means of a photosensor. CONSTITUTION:The image scanning area of the scanning lens 11 is from an image printing start position to an image printing finish position, and the area is a lens part 12. Both surfaces of the rib 14 are finished to be flat. The light beam at the leading edge part in a main scanning direction out of the light beams deflected by a polygon mirror 5 is transmitted through the rib 14 and emitted. A condensing (cylindrical) lens 16 and the photosensor 17 are set on the optical axis of the light beam. A horizontal periodic signal is generated based on a light beam detection signal by the photosensor 17, and the image printing start position for every scanning line on a photoreceptor drum 20 is decided. Namely, the dividing accuracy error of respective reflecting surfaces of the polygon mirror 5 is corrected.

Title: Picture coder and picture decoder
Inventor: WATANABE HIROMI
IPC: H04N19/61
Filed: 1990-07-13
Abstract: PURPOSE:To improve a coding efficiency and one-frame processing speed by adding a function comparing a current frame with a 2-preceding frame to the coder and decoder and sending only a code representing invalidity for a part discriminated when the both are equal. CONSTITUTION:A discriminator 5 discriminates a picture data from a frame memory and outputs a result representing whether the data is valid or invalid. A coder 10 applies orthogonal transformation to a block discriminated to be valid in a picture and applies quantization thereto and sends the result while allocating a code. Moreover, the coder 10 applies only code allocation of an invalid block to the block discriminated to be invalid and sends the result. Since a discrimination device 5 discriminates a valid/invalid part through the comparison with a representative value of a preceding frame, even a changing picture in an actual picture may be discriminated to be an invalid part. Then a valid frame per several frames is produced without fail in each frame of a picture data in a frame memory so that mis-discrimination is not caused for several consecutive frames.
