Title: Mask for exposure and its production
Inventor: ITO SHINICHI
IPC: G03F1/68
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To overcome the difference in the image intensity arising between a Lebenson phase shift region and non-Lebenson phase shift region by adjusting the recessed amt. of the non-Lebenson phase shift region. SOLUTION: This mask for exposure has the phase shift openings forming by making a recessed part in a part of a light-transmissible substrate 1 among the opening patterns of a light shieldable film 2 formed on this substrate 1. The phase shift openings are the openings of the min. opening size L having the periodicity constituted by alternately arranging the first opening pattern groups and second opening pattern groups where the optical path length differences to the exposing light transmitted through the non-recessed regions of the substrate 1 attain λ/2 and λ in one direction.  The image intensity for working both patterns at the desired sizes is made match with each other by making the recessed part on the substrate 1 when the image intensity of the non-phase shift parts is higher than that of the phase shift parts and by imparting the optical path differences of λ and λ/2 to the light transmitted through the non-recessed parts of the substrate 1 if the image intensity of the phase shift parts in higher than that of the non-phase shift parts.

Title: Rotation control system for cooling fun
Inventor: HIRATSUKA YOSHIAKI
IPC: F25D1/00
Filed: 1989-09-18
Abstract: PURPOSE:To reduce the noise level by providing a thermistor having the temperature-resistance characteristic of a large resistance change between a fan and a power supply and also a switch circuit between the thermistor and the fan to hold a fixed rotational frequency of the fan at a low temperature. CONSTITUTION:The number of revolutions N3 of a fan 1 is kept at a fixed level by a switch circuit 4 at a fixed temperature T3 or less within a resistance change area of a thermistor 3. Then the fixed level of the number of revolutions N3 is never lowered and therefore the noise level is reduced during the operation of the fan 1. At the same time, the number of revolutions N3 is increased as conventional with reduction of the resistance value OMEGA3 of the thermistor 3 at high speed rotation of the fan 1. As a result, the fluctuation width of the number of revolutions N3 can be increased and therefore kept at a low level even at a low temperature. Then the noise level is reduced.

Title: Magnetic recording medium and its production
Inventor: OGAWA YOICHI
IPC: G11B5/84
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To enable superior C/N characteristics by forming a metallic magnetic thin film comprising crystal grains of a specified grain diameter formed on a substrate so that the grain diameter of the crystal grains is increased as it goes from the substrate side of the thin film toward the outer surface side. SOLUTION: A metallic magnetic thin film 10 is formed from crystal grains of <=20 nm average grain diameter so that the grain diameters of the Co crystal grains 11 and Co-O crystal grains 12 are stepwise increased as they go from the substrate side of the thin film 10 toward the outer surface side. The grain diameter is controlled and formed by adjusting the temperature of a can while optionally combining the intrusion of an inert gas as well. By increasing the grain diameter of the crystal grains near the outer surface of the thin film 10, the crystal magnetic anisotropy of the grains is enhanced and output is increased. Because of the small crystal grains on the substrate side, magnetic domains are made small, noise is reduced and a C-N ratio is increased.  The tilt direction of the columnar crystal grains of a lower metallic magnetic layer 10a and an upper metallic magnetic thin film 10b may be changed.
