Title: Etching device and etching
Inventor: MORIMOTO MASAHIRO
IPC: H01L21/306
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To make the flatness of the surface of a wafer enhance by an etching of the wafer, to increase the surface quality of the wafer and also to prevent the generation of the deterioration of an etching liquid. SOLUTION: A silicon wafer is held on a rack 12 to rotate the wafer at a prescribed speed in an etching liquid and the wafer is etched. At this time, a gas feed pipe 13 is brought close to a position, where is apart by a prescribed distance from the rack 12. Inert gas is jetted through jet holes 13A at a constant speed. The etching liquid in the vicinity of the surface of the wafer is greatly stirred and a surface trace, such as a ring mark, is eliminated. After an elapse of a prescribed time, the pipe 13 is kept away by a prescribed distance from the above position in a state that the jet of the gas is continued (A gas pressure is constant.). As this result, the flatness of the surface of the wafer is improved and the deterioration of the etching liquid is also prevented from being generated.  Moreover, gas feed pipes are installed at two places in a liquid tank and the gas is sprayed on the wafer through the pipe directly under the wafer for a constant time and after that, the gas may be sprayed on the wafer through the pipe installed at the corner of the interior of the liquid tank. The pressure of the gas through the one feed pipe may be changed within an etching time.

Title: Double-sided linear motor
Inventor: TAKIGAWA TOSHIAKI
IPC: H02K9/04
Filed: 1988-10-03
Abstract: PURPOSE:To cool a primary side stator and a secondary conductor efficiently by sending a cooling air from the outside of coil ends on both sides through a ventilating gap to the traveling gap side by cooling fans provided in the manner of facing each other with the coil ends on both sides between. CONSTITUTION:Blade pieces 28a of respective cooling fans 28 are arranged to face each other with coil ends 25 on both sides in between. By rotation of the cooling fans 28, the outside air is absorbed into a fan cover 32 as shown by the arrow A and sent almost horizontally toward the coil end 25 as shown by the arrow B. A part of the cooling air hits the coil end 25 and flows along the coil end 25 as shown by the arrow C, but the cooling air mostly passes through the ventilating gap between respective coil ends 25 and flows to the traveling gap 22 side. Then, two flows of the cooling air hit each other from both sides of a secondary conductor 23 and the cooling air flows along both faces of the secondary conductor 23 and into the traveling gap 22.

Title: Disk incorporating cartridge
Inventor: MASUDA YUTAKA
IPC: G11B23/03
Filed: 1994-10-14
Abstract: PURPOSE: To prevent the generation of abnormal sound accompanying a defective chucking by dispersing a depressing force by extending contact area while bringing a flange part of a hub into contact with an upper half, and further reducing the coefficient of friction by roughening contact part. CONSTITUTION: When a spindle 20 of a driving device is inserted into the hub 5 of the disk cartridge, the thickness of the flange and the height of a rib 11 are set so that the hub 5 is depressed by a tip part of the spindle and the flange part 10 of the hub 5 is brought into contact with the inner surface of the upper half 7. Since the surface of the flange part 10 of hub 5 brought into contact with the inner surface of cartridge or the surface of the cartridge brought into contact with the flange part is roughened, the flange 10 of hub 5 and the cartridge 6 are slid without tight adhesion, therefore, the centering of the disk 1 is smoothly performed.

Title: Variable relief mechanism for four-wheel steering
Inventor: HARAYOSHI MITSUHIKO
IPC: B62D7/14
Filed: 1992-09-18
Abstract: PURPOSE:To enable steering at low speed large steering angles and prevent rear wheels from being steered to large steering angles in the vicinity of the neutral position by controlling a relief valve by a piston, providing the dead zone mechanism of the piston between piston driving crank mechanism and a piston pin, and providing an internal contact cam for pulling the piston back at the return time of a steering wheel. CONSTITUTION:When a steering wheel is in the neutral position, a poppet valve 35 is brought into pressure contact with a valve seat 32 by a spring 36, and the cam face 39a of an internal contact cam 39 comes in contact with a piston pin 42. When the steering wheel is steered, a connecting rod 40 moves through shafts 43, 37, and a piston 34 is placed in the inoperative state until the piston pin 42 comes in contact with the left end from the right end of an elongated hole 40 provided at the tip of the connecting rod 40. Thereafter, the spring force of the spring 36 becomes strong as the piston 34 moves to the right. When the steering wheel angle is reduced from the maximum angle, the piston 34 is pulled back to the left by the piston pin 42, that is, the internal contact cam 39 returns the piston 34 forcibly.
