Filed: 1995-03-16
Abstract: PURPOSE: To eliminate the need of filling the level difference by forming an SOI layer from an epitaxial layer formed on a first silicon substrate, forming a level difference between an insulation film pattern and the first silicon substrate, and bonding the surface of an epitaxial planalization layer to the surface of an insulation film on a second silicon substrate, thereby forming a thin SOT layer uniformly. CONSTITUTION: An epitaxial layer 5 is formed on the exposed pattern 4 side of a first silicon substrate 1 and an oxide pattern 3 while covering an oxide pattern 3. A level difference is formed inevitably between the exposed pattern 4 and the oxide pattern 3 upon formation thereof and thereby a gentle level difference is also formed in the epitaxial layer 5. Subsequently, the surface of the epitaxial layer 5 is polished to planarize the gentle level difference thus forming an epitaxial planalization layer 6. Finally, the surface of the epitaxial planalization layer 6 of the first silicon substrate 1 is bonded to the surface of an oxide 8 on a previously prepared second silicon wafer 7.

Title: Permanent magnet motor
Inventor: SHIOHATA HIRONORI
IPC: H02K1/27
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To suppress the appearance of a toroidal vibration mode which resonates with higher harmonic wave components of electromagnetic excitation force and thereby reduce vibration the noise of a motor, by controlling the rigidity of a toroidal vibration generating member which causes toroidal vibration due to electromotive force based on a specified formula, and preventing the resonance between a higher harmonic wave component space made of electromotive force and the toroidal vibration mode of the structure. SOLUTION: P-poles of a motor 1 is provided with higher harmonic wave components of electromotive force of the k-th space order. The space distribution mode is given by a formula=(p/2)m. At some places in the periphery of a magnet holding plate 21 of a rotor 2 of the motor 1, reinforcing materials are firmly joined in the longitudinal direction by welding, shrink fitting or the like, so as to satisfy the formula 1≠(2/n)m (n=1, 2, 3, and so on, N and N<=m). The placement of the reinforcing materials increases the radial flexural rigidity of the magnet holding plate 21, thereby increasing the rigidity against a toroidal vibration mode. Furthermore, a reinforcing material is joined also to an end plate 22 firmly and then secured. By determining the number of the reinforcing members according to a generated toroidal vibration mode, noise can be reduced.

Title: Thin plate material soaking device
Inventor: NIIHARA KAORU
IPC: B65G49/04
Filed: 1993-03-18
Abstract: PURPOSE:To prevent a thin plate material from springing out from a thin plate material housing part by arranging a housing part moving means to move a thin plate material housing part vertically in a liquid tank and a liquid flow forming means to form a liquid flow to the inmost side from an opening of the thin plate material housing part at least in the vicinity of a liquid level in the liquid tank. CONSTITUTION:When a cassette C housing vertically a large number of wafers W is positioned and loaded on a cassette stand 32 of a submerged loader 1 by a positioning member 33, a raising and lowering frame 19 is lowered, and soaks the cassette C in a water tank. At this time, pure water supplied from a pure water supply port 15 overflows from a dam 14. As a result, a water flow running toward the inmost side from an opening 13 of the cassette C is formed in the vicinity of a liquid level of the water tank. Thereby, when the raising and lowering frame 19 is lowered, the respective wafers W receive energizing force by the water flow, so that the wafers W do not slide out from the cassette C. Even when the wafers W are supplied to the reverse cleaning device 2 side, a pure water flow running toward the inmost side from the opening is formed in the vicinity of the liquid level.

Title: Wet developing device
IPC: G03G15/10
Filed: 1992-03-16
Abstract: PURPOSE:To easily form a liquid column of wet developer for developing at a high speed, without applying a high voltage power source by providing an opening member communicated with a developer chamber and providing the opening member with an opening width control means where opening width of the opening is maintained to be variable. CONSTITUTION:As recorded signal is inputted, electric signal is inputted to a solenoid 44 prior to developing, simultaneously, a mobile part 45 is made to be an elongated state by which the opening member 32 is pressurized and the opening width of the opening 30 is narrowed. Thus, due to capillarity, more quantity of the developer 42 is sucked into the opening 30 as compared to the quantity sucked in the inactive state, hence projected meniscus is formed at a position confronted with a photosensitive drum 1. Furthermore, the opening member 32 is pressurized by the mobile part 45 at a tip of the solenoid 44 to the opening width set by a spacing holding member. Thus, as the opening 30 and the photosensitive drum 1 are closely opposed to each other with a minimal gap, the projected menicus, as a consequence of growing, is brought into contact with the surface of the photosensitive drum 1 and the liquid column of the developer 42 is formed.
