Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To enable data to be retrieved at a high speed by dividing the data into time units, recording them as block data in a data area of a recording medium in the order of time and channel, and searching a block with reference to a directory consisting of time information and channel information of the block data. SOLUTION: Data stored in a recording memory 3 are grouped into blocks, each in a unit of 10 sec, by a microcomputer 4, and after time base compression processing, the blocks are recorded as the block data in the order of time and channel on a DAT tape 20 via a buffer memory 5. After completion of recording, a directory consisting of inputted time of the block data and flags showing the presence/absence of data in individual channels is recorded in a time unit of 1 sec in a directory area ahead of the DAT tape 20. At the reproducing time, a search is made by calculating a block member of data in existence to coincide with specified time and channel in reference to the directory read out of the directory area of the DAT tape 20 by the microcomputer 4.

Title: Production of partially dispersion strengthened type alloy
Inventor: WADA HIKARI
IPC: B22D15/00
Filed: 1985-09-27
Abstract: PURPOSE:To prevent a metallic oxide from floating on the surface or settling into a molten metal by liberating from a base metal by incorporating the particles of the metallic oxide into the molten metal and installing a chiller into the cavity of a casting mold. CONSTITUTION:An inert gas is passed in a passage 9a and a vibrator 9c operates just before a molten metal A is poured from a ladle 8 into a sprue 7. Then, a prescribed amt. of metallic powder M is added into the molten metal and is fed together with the molten metal into the sprue 7 to fill the inside of the cavity 2. Part of the molten metal is quickly cooled by the chiller 3 in this stage and is thereby quickly solidified; on the other hand, the molten metal is replenished from risers 4, 5 into the cavity 2 in the same manner as heretofore to prevent the generation of a shrinkage cavity and therefore, the metallic oxide incorporated into the base material is retained in the base metal without being liberated therefrom.

Title: Magnetic head
Inventor: HASEGAWA SABURO
IPC: G11B5/60
Filed: 1990-08-13
Abstract: PURPOSE:To eliminate the influence of temp. and humidity by holding a flat plate slider part formed by integral molding with a magnetic head core on the contact surface side with a magnetic disk to hold a gap side in such a manner that this slider part faces the recording surface of the disk. CONSTITUTION:The slider part 7 is formed by adding glass fibers and carbon graphite to an epoxy resin and molding the mixture integrally with the magnetic head core 1. After the slider part 7 is coupled to the top surface 11 of a metallic case 10, the contact surface 8 is formed by lapping. Since this part is coupled by grooves 6 on both side faces of the core 1, the core 1 and the slider part 7 are expanded and contracted by a change in temp. and humidity near the contact surface 8 but the difference therebetween is extremely small and is <=0.1mum. This difference is thus reduced to the extent of not affecting the recording and reproducing characteristics. The influence of moisture absorption, etc., is uniformly lessened by forming the slider part 7 to a thin flat plate shape.

Title: Variable dot printer
Inventor: NISHIKAWA MASAHARU
IPC: B41J2/415
Filed: 1990-08-15
Abstract: PURPOSE:To obtain printing results of different printing dot densities without an image distortion and density irregularities using a single ion flow printing head having ion emitting openings arranged at a predetermined pitch by a method wherein openings arranged at 1/2 P are used as adjusting means for changing a printing dot density. CONSTITUTION:An opening pitch in a main scanning line direction is substantially set to a constant pitch P. However, openings h1, h2, h5, and h6 arranged at approximately 1/2 P opening pitch are contained in the openings. By actuating this printing head as high-dot density printing dots, each dot position is corrected by a repulsive force of a preceding printing dot to ensure a good operation. On the other hand, at the time of a low-density recording, the same printing head is used, but a voltage too low to emit an ion is applied to openings 2, 6, which are accessed later out of openings 1, 2 and 5, 6. In addition, printing image data is distributed so as not to be assigned to the openings 2, 6. In this manner, a repulsive force between printing dots is reduced, and printing dots are obtained at a uniformly large dot pitch.
