Title: Electrostatic chuck device and preparation of the same
Inventor: OKANO HARUO
IPC: H01L21/265
Filed: 1982-04-28
Abstract: PURPOSE:To increase a chucking force and form a thin chuck structure preventing lowering of a chucking force due to the generation of bubble by forming a metal insulated layer through insulating process such as oxidation of stage surface. CONSTITUTION:Au is vacuum-deposited on the first metal insulated layer 42 formed by changing a part of Al stage 41 into Al2O3 by the anode oxidation method and electrode layers 43a, 43b are formed. After the Al film 50 is vacuum-deposited at the entire part, the Al film 50 is changed to the Al2O3 by the anode oxidation method and the second metal insulated layer 44 is formed. Thereby, an electrostatic chuck apparatus can be formed. In the apparatus thus obtained, since the metal insulated layer 42 corresponding to a sapphire substrate 2 is embedded in the stage 41 itself, disadvantage caused by adhering the sapphire substrate 2 to the stage 1 is no longer eliminated and a distance (d) between a permanent magnet 46 and the surface of sample 45 can be extremely shortened. Accordingly, a high speed etching can be realized without lowering the intensity of magnetic field on the surface of the sample.

Inventor: HASHIMOTO MASAHIRO
IPC: B24B37/00
Filed: 1989-03-24
Abstract: PURPOSE:To produce wires for lapping having required tapered part by bending the end sides of wires extending out of a holder along the outside surface of the holder so that mutual wires are kept in non-contact with each other and then immersing the above wires into an etchant at a fixed speed. CONSTITUTION:Respective ends of a single or plural wires 2 are extended out through one end of a holder 10 consisting of a corrosion resisting member divided in two in an axial direction by the length sufficient to form tapered part, and these wires 1 are held in the holder 10 by allowing the sections 11a, 11b of the holder 10 to abut each other. Respective end sides of the wires 1 extending out of the holder 10 are bending along the outside surface of the holder 10 so that mutual wires 1 mentioned above are kept in non-contact with each other. Then, the holder 10 is attached to a constant speed elevator 13 and is allowed to descend at a fixed speed to immerse the wires 1 from the bent part 15 side into an etchant 16, by which each wire 1 can be etched into a tapered state where the diameter on the bent part 15 side is reduced. By this method, the wires for wire lapping having the same stable quality minimal in variance can be obtained.

IPC: G02F3/00
Filed: 1995-03-30
Abstract: PURPOSE: To perform high-speed full light signal processing with high output, with a high S/N ratio, or at a high ON/OFF ratio by having a deflecting element and a nonlinear optical element having tertiary or over optical nonlinearity, within a laser resonator, and emitting the result of light signal processing by the control light introduced from outside the resonator, as a laser oscillation light. CONSTITUTION: A nonlinear optical element 14, which has tertiary or over nonlinear optical effect, is arranged for deflectors 15 and 16 arranged in cross nichols arrangement within a resonator. Here, if control light 12 deflected by 45 deg. from each azimuth of a deflector enters the nonlinear optical element 14 having tertiary or over nonlinear optical effect, the deflection of the laser oscillation light becomes elliptic, and it transmits the deflector 15. When the amount of transmissivity gets over the threshold of laser oscillation, laser oscillation occurs, and a signal light 111 is emitted. That is, the laser beam switched by the control light is outputted as a signal light.

Inventor: CHIBA TOMIO
IPC: H03H19/00
Filed: 1984-04-13
Abstract: PURPOSE:To attain setting of a coefficient by 1% step by using in common a capacitor for setting a coefficient of 1% step and 10% step and using further a capacitor ratio and a switched capacitor type voltage divider together. CONSTITUTION:A circuit I is the switched capacitor circuit (equivalent resistance) corresponding to a feedback resistor to connect the circuits in parallel thereby preventing an opeational amplifier circuit from being in an open loop. Moreover, a circuit A is a voltage divider decreasing an output voltage of a circuit IV setting the coefficient by 1% step to 1/10. In selecting the capacitor ratio of capacitors C21, C22 and coefficient setting capacitors C11-C110 in the circuit I as 10:1, the output voltage V0 becomes V0=(total capacitance of capacitors selected in the C11-C110/C21 or C22) (1/10 of VIN+VIN) and since the C21 and C22 have a capacitance value being 10 times the C11-C110, the coefficient setting by 1% step is attained.

Abstract: PURPOSE:To prevent breakdown in a gap between a photosentitive drum and a developing roller by not only increasing a DC voltage impressed on a supply roller but also adjusting the ratio of the linear velocities of the supply roller and the developing roller in the case of making the density of a copied substance high. CONSTITUTION:By rotating the developer supply roller 4, magnetic brush is formed on the surface of the roller 4. When the DC voltage is impressed on the roller 4, only non-magnetic toner in the magnetic brush is attracted to the surface of the developing roller 3 and then a toner layer is formed. By impressing the specified DC voltage on the roller 3, the non-magnetic toner in the toner layer flies and adheres to an electrostatic latent image on the photosensitive drum 1, so that development is performed. The adjustment of the density of the copied substance at this time is executed by controlling either or both of the DC voltage impressed on the roller 4 and the ratio of the linear velocity of the rotation of the rollers 4 and 3. Thus, the excellent copied substance is obtained without causing the breakdown in the gap between the photosensitive drum 1 and the developing roller 3.

Abstract: PURPOSE:To enable the non-orientation of even ferromagnetic particles and to suppress the generation of output fluctuations by disposing a rotatable magnet at the angle of the rotating face specified with respect to a coated base to one or both sides of the base before the coating compd. of the base dries and treating the base by this magnet. CONSTITUTION:The nonmagnetic base 1 which travels in one direction is treated by at least one rotatable magnet 3 disposed in such a manner that the rotating face thereof has 5-30 deg. angle of inclination with the base 1 to one or both sides of the base before the magnetic base 2 dries right after said compd. 2 is coated on the base 1. The magnetic lines of force of the magnetic field applied on the base are not effective any more because of the roughening of the coated surface if the angle of inclination is below 5 deg.. On the other hand, the magnetic lines of force are no longer able to act sufficiently on the base and are not effective any more if the angle is mover 30 deg.. The non-orientation of even the ferromagnetic particles is thereby enabled and the generation of the output fluctuations is decreased.
