摘要： In a method and an apparatus of orientation treatment of an orientation film according to the present invention, the surface of a orientation film formed on a substrate for orientating liquid-crystal molecules is rubbed in a predetermined direction. Thereafter ion beams are radiated onto the orientation film in a vacuum in a direction different from the rubbing direction, that is, in the direction obliquely above the orientation film surface. In the method, these steps can be reversed.

摘要： PROBLEM TO BE SOLVED: To make it possible to lessen the generation of particles and to simplify treating stages by irradiating the unbaked oriented film formed on a substrate with an ion beam simultaneously with or after the impression of a magnetic field and executing the orientation treatment and curing of the oriented film by the irradiation. SOLUTION: A vacuum vessel 24 is internally equipped with a holder 8 for holding a substrate 2 with the oriented film to be subjected to the orientation treatment. The vessel is provided with a solenoid-like coil 16 which is disposed to enclose the holder 8 and impresses the magnetic field 18 from a prescribed direction on the oriented film 6 of the substrate 2 with the oriented film on the holder 8. The vessel is also provided with an ion source 20 for irradiating the oriented film 6 of the substrate 2 with the oriented film on the holder 8 with the ion beam 22. An exciting current is supplied to the coil 16 from a DC power source. The ion source 20 is arranged on nearly the central axis of the coil 16 to make the magnetic field by the coil 16 and the ion beam 22 from the ion source 20 incident on the oriented film 6 of the substrate 2 with the oriented film on the holder 8 nearly parallel with each other.

摘要： PROBLEM TO BE SOLVED: To simplify a stage for an orientation treatment and to prevent the generation of particles at the time of the orientation treatment by simultaneously executing the baking and orientation treatment of the unbaked and oriented film by irradiation with an ion beam. SOLUTION: A vacuum vessel 20 which is evacuated to a prescribed vacuum degree, a holder 8 which is disposed in the vacuum chamber 20 and holds a substrate 2 with the oriented film to be subjected to the treatment and an ion source 12 which is mounted at the vacuum chamber 20 and irradiates the oriented film 6 of the substrate 2 with the oriented film on the holder 8 with the ion beam 14 are disposed. The holder 8 is constituted rotatable like an arrow A round a central shaft 10 in such a manner that the irradiation angle θof the ion beam 14 with the surface of the oriented film 6 may be changed. The oriented film 6 which is unbaked and is disposed on the substrate 4 is irradiated with the ion beam 14 in the vacuum atmosphere, by which the baking and orientation treatment of the oriented film 6 are simultaneously executed.

摘要： PURPOSE: To obtain high orientability even for an oriented film which is hardly subjected to a rubbing treatment by irradiating this oriented film with ion beams. CONSTITUTION: A substrate 2 with the oriented film is formed by applying the oriented film 6 consisting of a high-polymer org. material, such as polyimide, on the surface of, for example, a glass substrate 4. The surface of the oriented film 6 is irradiated with the ion beams 14 by sharpening an irradiation angle θfrom diagonal above at the time of the orientation treatment. The orientation order angle of liquid crystals increases as the irradiation angle 6 is set smaller and, therefore, the setting of this angle at the smaller value is more preferable. The direction of the irradiation on the oriented film 6 with the ion beams and the rubbing direction to the oriented film 6 are set at nearly the same directions even if whichever treatment is execute first. Both treatment directions to the same oriented films 6 are eventually unified and the respective orientation treatments make up each other if both are set in nearly the same directions and, therefore, the same rubbing directions are more preferable for obtaining the higher orientability.

摘要： PURPOSE:To suppress the generation of particles and static electricity and to improve the yield of a liquid crystal display by irradiating an oriented film with excimer laser light through a mask which has many mutually parallel slit holes. CONSTITUTION:A lens 26 and the mask 22 are provided above a holder 13 and a laser light guide-in window 20 for guiding in the excimer laser light 18 outputted by an external excimer laser light source 16 is provided further above them. Then the oriented film 8 is irradiated with the excimer laser light 18 through the mask 22 which has the mutually parallel slit holes 24 and then the light energy is converted into machining energy by physical abrasion to form many infinitesimal grooves on the surface of the oriented film 8. Consequently, liquid crystal molecules are oriented along the grooves. Thus the orienting processing of the oriented film 8 can be performed by non-contact by the method which converts the light energy of the excimer laser light 18 into the machining energy.

摘要： PROBLEM TO BE SOLVED: To obtain the cured body of colored cement which fades less in color in spite of long-term exposure to natural environment by kneading pigments subjected to a low-temp. plasma treatment, the raw material for the cured body of hydraulic cement and water and curing the mixture. SOLUTION: An electrode 8 in common use as a vessel housing the powder pigments 12 and a high-frequency electrode 10 are arranged to face each other in a vacuum vessel 2. Next, the inside of this vacuum vessel 2 is evacuated to vacuum and thereafter, gaseous oxygen, inorg. gas, such as CO2 , N2 or He or steam (6) is introduced from a gas introducing port 4 into the vacuum vessel. The pressure in the vacuum vessel 2 is maintained at 10 to 10 Torr. High-frequency electric power is then impressed between the electrode 8 in common use as the vessel and the high-frequency electrode 10 via a matching device 16 from a high-frequency power source 18 to generate low temp. plasma 20. The surfaces of the pigments 12 are made hydrophilic by subjecting the pigments 12 to the low-temp. plasma treatment while the pigments are vibrated by an excitation device 14. Such pigments 12 and the raw materials for the cured body of the hydraulic cement, such as cement, silica and aggregate and water are kneaded. The mixture is then molded and the molding is cured.

摘要： PURPOSE:To suppress the generation of particles and static electricity at the time of an orientation treatment and to improve the yield of a liquid crystal display by irradiating the orienting film with an electron beam within a vacuum through a mask which has many mutually parallel slit holes. CONSTITUTION:On a holder 13 provided in a vacuum container 12, a substrate 2 with the oriented film to perform the orientation treatment is mounted. Further, an electron beam source 14 which orients to the holder 13 is provided in an upper direction of the mask 22 provided above the holder 13. When the oriented film 8 is irradiated with the electron beam 16 through the mask 22 having many mutually parallel slit holes 24, the surface of the oriented film 8 is fused and vaporized by means of thermal energy and many infinitesimal grooves are formed on the surface of the orienting film 8. When many grooves are formed, liquid crystal molecules are oriented along the grooves. Consequently, the orienting processing on oriented film can be performed by means of non-contact.
