Title: Palette for use in storing drum cans
Inventor: TOYAMA NORIHIDE
IPC: G21F9/00
Filed: 1987-12-04
Abstract: PURPOSE:To efficiently save a storing space of drum cans, by vertically stacking a plurality of drum cans and connecting the same with each other by means of palettes intervening therebetween. CONSTITUTION:A palette P is provided with four circular recesses on both upper and lower surfaces thereof, respectively. Each recess is formed in such a size that the peripheral rim portion of drum cans is appropriately received therein. In each recess, there are disposed a central pushbutton 4 and four connecting plates 2 which serves as connecting means between the palette and can and extend radially from the central pushbutton. The palette is also provided with four bores 3 at its corner edges, through which anchor bolts are inserted and threaded into the floor. When the end of the drum can is placed in the recess, the pushbutton is depressed due to the tare of the can. As a result, while a roller 8 of the connecting plate 2 rides over the sloped side wall of the pushbutton, the connecting plates are displaced inwardly to the pushbutton because they are biased toward the center of the recess by means of the spring 7. At this time, a hook 9 formed at the opposite end of the connecting plate is engaged with the rim portion of the drum can to thereby establish a secure connection between the palette P and the drum can D. Since the lowermost palette is anchored to the floor by bolts 10 inserted through the bores 3, a plurality of the drum cans stacked by intervention of palettes are, as a whole, securely fixed on the floor.

Title: Apparatus for controlling gyroscopic sensor
Inventor: MIZUNO SUEYOSHI
IPC: G01C19/00
Filed: 1988-12-05
Abstract: PURPOSE:To prevent the erroneous conversion of angle data by providing a low-pass filter with respect to the noise of a power supply system superposed on the signal from a sensor and providing a digital filter with respect to the noise at the time of the conversion to a digital signal. CONSTITUTION:When high frequency noise is superposed on the angular velocity data fomega from a gas rate gyroscopic sensor 11, said noise is removed by a low- pass filter 12. The data fomega is amplified to data kfomega through an amplifier 13 and the data kfomega is converted to digital data by an A/D converter 14 while the digital data is further integrated at every unit time by an integration circuit 15 to be outputted as angle data theta. The removal of the noise or unexpected noise superposed on the original signal is executed at the time of A/D conversion by an index smoothing/moving averaging processing part 16. Index smoothing processing applies differential approximation to the superposed noise component using differential operation to remove said noise component. Moving averaging processing applies averaging operation to the unexpected noise to remove the same. By this method, even minute angular velocity data is accurately outputted as angle data.

Title: Substrate washing method and washing device
Inventor: NATSUME NORIYUKI
IPC: G03F1/82
Filed: 1992-10-22
Abstract: PURPOSE:To enable the repeated use of a clean washing liquid, to reduce the washing cost and to enable the effective washing by condensating the steam generated by heating the washing liquid through a reflux pipe and washing the substrate by dropping this condensate on the substrate. CONSTITUTION:The washing liquid in a liquid-stagnated part 8 of a washing chamber 4 is warmed up with a heater 9 to become the steam 7, which is then cooled and condensated with the reflux pipe 2 to become the washing liquid again. The washing liquid thus condensated is dropped on the entire surface of a photomask 5 held by chucks 6 for supporting the photomask. At this point of time, the washing liquid condensated with a spacer 3 is uniformly dropped on the entire surface of the photomask 5. Further, when washing is carried out while providing the photomask 5 on a spinner, foreign matters and the washing liquid are easy to remove, thus washing is quickened. Moreover, it is preferable that a dehydrating part incorporating silica gel or the like is placed on the upper part of the reflux pipe to prevent moisture mixing from the upper part. By dropping the circulated washing liquid directly on the substrate in the above-mentioned manner, the continually new washing liquid is repeatedly used.
