Title: Japanese data compressing system
Inventor: FURUKAWA MASATO
IPC: G06F5/00
Filed: 1991-03-12
Abstract: PURPOSE:To reduce a storage area to be used for a Japanese data compressing system. CONSTITUTION:A data dividing part 3-2 divides Japanese data which are data 3-1 to be compressed into plural fixed length parts. A data array conversion part 3-3 sends the divided Japanese data to the storage area 8 and rearranges the Japanese data so that upper bytes and lower bytes are respectively continued. When the continued byte data are the same in a data string newly formed by rearrangement, a data compression part 3-4 converts the continued byte data into two byte data and their repeating frequency to form compressed data 3-5.

Title: Packaging electronic component
Inventor: WATANABE SATORU
IPC: H01L23/28
Filed: 1993-03-29
Abstract: PURPOSE:To reduce the size of an electronic component itself without reducing the number of leads protruded from an insulating substrate by forming the planar shape of the insulating substrate so that the substrate can become longer than the external line of an assumed planar shape of the substrate and can include the external lines of the substrate inside the assumed shape by assuming a minimum square or rectangle containing the external lines of the substrate. CONSTITUTION:The planar shape of a resin 4 sealing the joining sections of leads 9a and 9b with pattern groups 7a and 7b, an insulating substrate 5, and LSI chip 3 as an insulating base material is formed in a cross so that the length of the cross can become the same as the external line of a square virtual diagram G containing the first end faces 4a of the resin and the second end faces 4b of the resin on the inside of the end faces 4a can be included in the diagram G. Therefore, the size of an electronic parts mounting device 1 can be reduced without reducing the number of leads, since the area of the resin 4 can be reduced without reducing the pitch and number of leads from the conventional example. In addition, since the size of the device 1 is reduced, the occupying area of the device 1 on a printed wiring board is reduced and the degrees of freedom in the design of conductor patterns and arrangement of parts can be increased.

Title: Bearing
Inventor: CHIKU KAZUYOSHI
IPC: F16C17/02
Filed: 1983-04-25
Abstract: PURPOSE:To prevent each part from its wearing and damage, by both communicating a fine gap to a separately provided enclosed air chamber and filling over a part of the fine gas and the enclosed air chamber with bearing fluid. CONSTITUTION:A fine gap 3 is communicated to a separately provided enclosed air chamber 8 through a fine hole 6 and a pipe 7, while the fine gap 3, fine hole 6, pipe 7 and the enclosed air chamber 8 are filled with bearing fluid 9. In this way, when a shaft 1 is stopped or rotated at a low speed, the bearing fluid 9, existing in the fine gas 3, serves to perform the lubricating and cushioning action, while as a speed of the shaft 1 increases the fine gap 3 removes the bearing fluid 9, acting as an air dynamic pressure bearing. Accordingly, the shaft 1, while it is rotated, is never suspicious to come into direct contact with a supporting member 4, thus each part can be prevented from its wearing and damage.
