Title: Thin-film magnetic head
Inventor: KOMAKI KENJI
IPC: G11B5/31
Filed: 1994-08-22
Abstract: PURPOSE: To attain high-density magnetic recording by preventing the generation of the sub-peaks of a negative polarity in reproducing waveforms without entailing a stage for molding a magnetic pole part to a specific shape. CONSTITUTION: A magnetic recording medium-facing surface 9 is provided with a thin magnetic layer 10, by which an effect of substantially extending the magnetic pole length is generated and the sub-peaks of the negative polarity are eliminated without deterioration of output value. The high-density magnetic recording is thus attained. The magnetic pole part is merely provided with the thin magnetic layer 10 without entailing the stage for working and molding this part to the specific shape. Such magnetic pole is advantageous in that the production thereof is easy.

Title: Orientation flat aligning system for wafer
Inventor: KASHIWAGI NOBUO
IPC: B23Q16/02
Filed: 1983-11-24
Abstract: PURPOSE:To perform orientation flat alignment of wafer under transportation through simple system by attracting a pair of wafers on caryying belt to the table then rotating and lifting thereafter detecting the orientation flat position through a sensor and aligning the same. CONSTITUTION:Upon feeding of a wafer in a cassete 1 through carrying belts 2, 3 to the stoppers 14, 14, it is detected by a sensor 25 to stop motor 4 with such timing as making reliable contact with the stoppers 14, 14. Then, the positioning pins 20, 20 are projected to advance a pushing member 18 thus to move the stoppers 14, 14 while to rotate the motor 4 reversely and to push the wafer W against the pins 20, 20. Since the wafer W is housed in such direction as the orientation flat will not touch the pins 20, 20, the circular outercircumference will touch the pin thus to position coaxially with the table 6. Thereafter, the table 6 is rotated and lifted to make contact with the lower face of wafer W and attract it, then it is lifted from the belt 3 and rotated and upon the orientation flat reaching predetermined position, the sensor 24 will stop the motor to complete positioning.

Title: Character reader
Inventor: MUKAI SHINJI
IPC: G06K9/66
Filed: 1985-10-04
Abstract: PURPOSE:To improve the accuracy of recognition by using an inputted image information as a reference pattern, setting up the storing size of a dictionary pattern on the basis of the reference pattern and recognizing the image information on the basis of the formed dictionary pattern. CONSTITUTION:To form dictionary patterns, various dictionary patterns are formed on the basis of characters or codes image picked up by a camera 16, the dictionary pattern storing size of a dictionary memory part 22 is set up on the basis of the size of the characters or codes and the dictionary patterns are transferred and stored to/in the dictionary memory 22. Thereby, the dictionary patterns can be formed without using a specific device for the formation of dictionary patterns. Since the dictionary pattern storing size to the dictionary memory part 22 is set up on the basis of the characters or codes image picked up by the camera 16 at the recognition of the characters, it is unnecessary to normalize the binary image information inputted to a character pattern memory part 21, so that the accuracy of recognition can be improved.

Title: Heat exchanger
Inventor: AZEYANAGI ISAO
IPC: F25B39/04
Filed: 1992-08-20
Abstract: PURPOSE:To reduce the displaced current of a fluid and hereby improve a heat exchange efficiency by forming a swirling fluid flow flowing in a circular fluid passage of a heat exchanger with use of a spiral inner fin. CONSTITUTION:A refrigerant flowing through each refrigerant passage 2a in a tube 2 flows along a spiral inner fin 6 inserted into the refrigerant passage 2a to form a swirling flow. Such formation of the swirling flow of the refrigerant flowing in the refrigerant passage 2a causes centrifugal force following the swirling flow to act on the refrigerant. For this, rather a fluid refrigerant having a greater specific gravity than a gas refrigerant flows along an inner wall surface of the refrigerant passage 2a, and the gas refrigerant forms an annular flow, most of which flows through a central portion of the refrigerant passage 2a. Thus, heat exchange is effected on a cross section of the refrigerant passage 2a, i.e., over the entire peripheral wall surface of the refrigerant passage 2a to promote heat transfer.

Title: Winding method of thin belt of amorphous magnetic alloy
Inventor: AWA MIKIO
IPC: H01F41/02
Filed: 1984-10-24
Abstract: PURPOSE:To enable high-speed winding without causing a damage, by passing a thin belt of an amorphous magnetic alloy on barrel-shaped tension rollers bulging out in the middle in the axial direction, so that the belt can be wound in superposition. CONSTITUTION:A thin belt 1 of an amorphous magnetic alloy is passed on barrel-shaped tension rollers 6-9 so that it can be wound in superposition. For instance, the thin belt 1 of an amorphous magnetic alloy is passed on a parallel roll 4, and further it is passed on pairs of barrel-shaped tension rollers 6 and 7, and 8 and 9, so that it moves in the shape of S on the respective pairs of rollers, and then fixed on a winding bobbin 11 fitted to a roll shaft 10. Thereafter the thin belt 1 is wound in superposition on the winding bobbin 11 by rotating the roll shaft 10. When the tension rollers 6-9 bulging out in the middle in the axial direction rotate at high speed, a centripetal force act on the thin belt 1 of the amorphous magnetic alloy so that it draws the thin belt 1 toward the central part in the axial direction and thus controls the meandering movement of the belt. By this method, high-speed winding of the thin belt of the amorphous magnetic alloy can be performed without causing the damage thereof.
