摘要： A magnetic film forming system which can always apply a magnetic field to a substrate in a constant direction. The magnetic film forming system comprises a vacuum container, a substrate pallet for holding a substrate in the vacuum container and being removable with the substrate held, from the vacuum container, and means for supporting the substrate pallet. Magnetic field generation means are fixed to the substrate pallet for applying a magnetic field to the substrate. When the substrate pallet is removed from the vacuum container, the magnetic field generation means are also taken out together with the substrate.

摘要： A magnetic film forming system which can always apply a magnetic field to a substrate in a constant direction is disclosed. The magnetic film forming system includes a vacuum container, a substrate pallet for holding a substrate in the vacuum container and being removable while still holding the substrate, from the vacuum container, and means for supporting the substrate pallet. Magnetic field generation means are fixed to the substrate pallet for applying a magnetic field to the substrate. When the substrate pallet is removed from the vacuum container, the magnetic field generation means are also taken out together with the substrate.

摘要： A laser marking apparatus comprises a pulse laser oscillator which emits a linearly polarized laser beam; a transmission type liquid crystal mask which displays a pattern to be marked on an article in one of a positive pattern display mode and a negative pattern display mode by dots arranged in a matrix form and which allows to pass the emitted laser beam but differentiates the polarization plane of the laser beam which has passed through masked portions from that through unmasked portions; a polarized beam splitter disposed downstream the transmission type liquid crystal mask for selectivity passing the laser beam to be irradiated on the article to be marked from the transmission type liquid crystal mask; a TV camera for detecting a discriminator indicating the thermal conductivity of the article to be marked; a recognition unit which determines the thermal conductivity of the article to be marked based upon the detected discriminator; and a control unit which controls the transmission type liquid crystal mask to operate in one of the positive pattern display mode and the negative pattern display mode based upon the determined thermal conductivity of the article to be marked in such a manner that when the determined thermal conductivity of the article to be marked is low, the positive pattern display mode is selected and when the determined thermal conductivity of the article to be marked is high, the negative pattern display mode is selected.

摘要： A laser marking system of the present invention is provided with an irradiation position changing device on a laser beam path for changing the irradiation positions of the laser beam corresponding to each marking area when a marking area including a plurality of irradiation marking areas is formed by irradiating the workpiece with the pulse laser beam which has passed a pattern of a mask. The plurality of irradiation marking areas are successively irradiated with the pulse laser beam from an irradiation position to form a marking area. Since the marking area larger than each irradiation marking area can be obtained, the whole laser marking system can be made smaller in size without increasing the output power of the pulse laser generator.
