Patent number: 6700673Abstract: An image-reading apparatus is provided with a plurality of buffer units between an image-reading unit 6c for reading an image on paper P fed one after another consecutively and an interface 8 for outputting an image data to a host computer 9. The image-reading apparatus suspends feeding of the paper P and reading of the image, and stops operation of its own after all of the image data is output from the buffer unit wherein the image data is written, when operation of a scanner is stopped or temporarily suspended. The invention can thus provide the highly reliable image-reading apparatus that is capable of outputting the entire image data it reads from the original paper without losing it, even if the operation is terminated in the midst of a continuous reading.Type: GrantFiled: December 16, 1999Date of Patent: March 2, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takeyasu Saito, Hironori Tomooka

Patent number: 6674633Abstract: A method for the fabrication of a cap layer on a top electrode layer of a ferroelectric capacitor includes the steps of depositing an amorphous layer, usually made of Sr(x)Ru(y)O3, on the top electrode and then annealing the amorphous layer in two stages in order convert the amorphous layer into the cap layer. The first anneal is performed at 500° C. to 700° C. in a non-oxidizing atmosphere, such as nitrogen, and converts the amorphous layer into a crystallized layer of Sr(x)Ru(y)O3. The second anneal is performed at 300° C. to 500° C. in an oxidizing atmosphere, such as oxygen, and converts the crystallized layer into the cap layer. The method is applied to the formation of a ferroelectric capacitor element of an integrated semiconductor device.Type: GrantFiled: February 28, 2001Date of Patent: January 6, 2004Assignee: Fujitsu LimitedInventors: Shan Sun, George Hickert, Katsuyoshi Matsuura, Takeyasu Saito, Soichiro Ozawa, Naoyuki Satoh, Mitsushi Fujiki, Satoru Mihara, Jeffrey S.
