Title: Magnetically coupled rotation transmitting device
Inventor: SAIJIYOU MASARU
IPC: F16D27/00
Filed: 1979-07-03
Abstract: PURPOSE: To relase the attraction force between magnets as well as reduce the sliding wear of a thrust bearing for the magnet to be driven by letting a static pressure difference generate between both sides of the driven magnet and applying the force due to this pressure difference directly to the driven magnet.  
     CONSTITUTION: Revolutions of a drive magnet 12 operated through a motor shaft 13 rotates a driven magnet 6 by magnetic coupling and further a rotor 14 composing a pump, and thus a pumping operation is performed. At this time, the driven magnet 6 has freedom in the axial direction and is drawn by the drive magnet 12, but can hold a constant position as the end bearing 10 contacts a seal plate 11, where the following relation is maintained: Width of the coupled side gap A>width of the uncoupled side gap B. Accordingly the relative speed is generated between the fluids in the gaps A and B when the driven magnet 6 rotates, setting the static pressure at A side higher than the one at B side. Thus the leftward pushing force is applied to the driven magnet 6.

Title: Semiconductor laser
Inventor: OGATA SHIGEYOSHI
IPC: H01S5/22
Filed: 1981-06-01
Abstract: PURPOSE:To reduce the threshold values making the laser beam narrower by a method wherein the forbidded band width of the semiconductor wave guide layer is a bit wider than that of the semiconductor active layer while the forbidden band width of the semiconductor wave guide layer and the semiconductor active layer is made a bit narrower than that of the semiconductor layer.

Title: Nonvolatile semiconductor storage device and its manufacture
Inventor: OTA YUTAKA
IPC: H01L29/788
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To increase the number of times of writing and erasing for a split gate type flash EEPROM (nonvolatile semiconductor device electrically capable of programming and erasing) and reduce the writing disturbances. SOLUTION: This storage device has a structure in which a floating gate 7 and a control gate 4 are exchanged in a conventional split gate type flash EEPROM. A large number of semispherical grains 3a are formed on the control gate 4. From the tips of sharp protruding parts 7a of the floating gate 7 facing the grains, Fowler-Nordnheim(FN) tunnel current is made to flow. Since there are many protrusions, even if a tunnel insulating film 5 covering one protruding part 7a is deteriorated, the tunnel current flows from the other protrusions, so that the life of an EEPROM cell is prolonged.

Title: Data transmission system
Inventor: YABUSHITA MASAHARU
Filed: 1985-04-24
Abstract: PURPOSE:To attain data transmission control according to a processing speed by performing the relaying transmission through each transmission controller based on the information recorded to the reception data and independently of the data receiving order when the transmission controller receives data from another transmission controller. CONSTITUTION:Plural pieces of FIFO are provided within a transmission controller and the connected FIFO are switches according to the information recorded to the reception data. Furthermore how to extract data out of the FIFO is controlled to perform the relaying transmission independently of the receiving order. The extracting rate and frequency of data out of plural FIFO are changed according to each FIFO to vary the relaying transmission rate of the data of each FIFO. When the priority is selected as the information to be recorded to the reception data, the relaying transmission is impossible with the reception data having low priority as long as the data having higher priority is contained in the FIFO. Thus the reception data of low priority are transmitted with relaying during the processing of the data having higher priority.
