Abstract: PROBLEM TO BE SOLVED: To automatically character-compose so as to produce a good balance for the entire character columns, by gradually moving and arranging the following character adjacent to the preceding character. SOLUTION: A Japanese character 'book' is arranged at a starting point X1 on a reference line L. Then, a following Japanese character 'is' is moved to the negative side of the line L for a beforehand determined size T0 (a trial movement amount) from the position where one side end of a square frame 'b' is approximately coincided with an end point X2 of the preceding character 'book' as shown in the broken lines. Note that the first trial movement amount T0 is set to 1/2 of the lateral size of a square frame 'a' of the character 'book', for example. Then, a discrimination is made to check whether an overlapping portion exists or not between the character 'book' and the character 'is' under the stated condition.  If there exists an overlapping portion indicated by a black paint, the character 'is' is temporarily moved to the positive side of the line L for a size T and is put back to the original position. Then, the character is moved to the negative side of the line L for a size T1 which is equivalent to 1/2.To so that judgment is again made to check whether an overlapping portion exists or not between the preceding and following characters.

Abstract: PURPOSE:To make it possible to keep a density of a print type constant even if temperature changes by providing at a nozzle a form memory material for indicating a reversible form memory effect so as to store previously transformation temperature and deformation quantity of the form memory material in conformity with changes of temperature of an ink being used. CONSTITUTION:A TiNi memory alloy 1, which is attached to the back face of a nozzle 2 i.e. to the inside of a head, is treated with reversible form memory. Generally, viscosity of ink is high at low temperature and low at high temperature. Accordingly, in order to make a diameter of a nozzle large at low temperature and small at high temperature, respective forms are stored in the memory alloy 1 based on data of the viscosity of the ink. Accordingly, a form memory material attached to the inside of the head contacts with the ink all the time and changes its form in accordance with changes of the temperature of the ink. Thus, the form memory alloy serves as a second nozzle by keeping quantity of ink drips ejected from the nozzle constant, so that the density of a print type can be kept constant.

Title: Magnetic recording disk medium
Inventor: IHARA MASASHI
IPC: G11B5/66
Filed: 1992-07-14
Abstract: PURPOSE:To improve durability and secure a stable quality by achieving a diamond thin film by the plasma CVD method for the structure of a magnetic disk medium. CONSTITUTION:A diamond thin film is grown on a non-magnetic film of a substrate for 3.5'' magnetic disk medium by the plasma CVD method. The film thickness is approximately 50-200Angstrom  and the film hardness is 3000-5000Hv. A high-performance magnetic film is formed within vacuum on the diamond thin film. Since the diamond thin film is extremely stable (against temperature and humidity) within vacuum, a ground layer (Ni-P electroless plating) which is a non-magnetic material is not affected by temperature/humidity within vacuum due to influence of the diamond thin film, thus forming a high-performance magnetic layer stably. A friction coefficient can be maintained to be a proper state after repeated tests for CSS(Constant Start Stop) among items for durability.
