Abstract: Two magnetic heads having different azimuth angles are mounted on a cylindrical rotary drum at a spac­ing. The data is recorded in a magnetic tape by means of the magnetic heads mounted on the rotary drum. On the magnetic tape, one track formed by one of the magnetic heads and other track formed by the other magnetic head compose one frame. The data is recorded in the unit of one frame. When reproducing, the data recorded in one track is read out by one magnetic head, and the data recorded in the other track is read out by the other mag­netic head. 
     When reproducing in the normal direction, the data in one frame is first read out on one track, and then on the other track. When reproducing in the reverse direc­tion, first the data of the other track is read out, and the data is fed into a delay circuit composed of memory and others. The delay circuit, after the data of one track is read out and output, outputs the data of the other track. Therefore, also in reproduction in the reverse direction, the data composing one frame is output in the same sequence as in reproduction in the normal direction.

Abstract: One of the greatest feature of the spinning method of the present invention is, in a spinning method employing the so-called melt-blowing method, notches are formed in the tip portions of capillaries of a melt-blowing die. This allows, during spinning, a high-speed gas blowing from orifices of the die to flow through the notches whereby the flow of a molten resin being extruded through each capillary is divided into two parts or more. Also disclosed is a melt-­blowing die having capillaries formed with these notches. According to the present invention, it is possible to prevent fibers from becoming entangled or ball-shaped.

Abstract: An X-ray exposure system, for exposing a semiconductor wafer to a mask with X-rays contained in synchrotron radiation, is disclosed. In this system, the mask (1) and the wafer (46) are held on a main frame (4) so that their surfaces extend substantially in parallel to a vertical axis. The main frame suspends from a supporting frame (10) through a plurality of air mounts (7) each being displaceable vertically. The supporting frame is placed on the same reference surface as of a SOR ring (17) that produces synchrotron radiation (20). By using these air mounts, any tilt of the mask and the wafer relative to the irradiation region of the synchrotron radiation as well as the position of the mask and the wafer in the vertical direction, with respect to the irradiation region, can be controlled and maintained constant. Thus, accurate pattern printing is ensured.

Abstract: A digital image display apparatus for converting a pixel value of medical digital image data such as MRI image data or CT image data into brightness in accor­dance with a display window including a window level and a window width of a display unit, determines the optimum window level and width for each image as follows. The apparatus obtains a histogram of pixel values from the digital image data and calculates brightness data of a pixel value having a highest frequency, brightness data of a pixel value at a boundary between a background and an image, area data of a portion having middle bright­ness within a display brightness range, area data of a portion having maximum brightness, and data indicating a ratio between an area of a portion having higher bright­ness than the middle brightness and an area of a portion having lower brightness than that obtained, when the digital image is to be displayed by a given display win­dow on the basis of the histogram. The apparatus obtains image quality indicating clarity of the image displayed by the given window on the basis of the above data by using arithmetic operations or by using a neural network, thereby determining the optimum display window which provides a maximum image quality.

Abstract: A flying head slider for supporting a magnetic transducer includes a pair of coplanar side rails (22, 23) to define a recessed section (24) therebetween. The recessed section (24) is open both at leading and trailing ends of the slider (21) . Each of the side rails (22, 23) has a tapered section (22a, 23a) at the leading end for receiving an air flow caused by a moving recording medium (5) to introduce the air flow under the corresponding side rail (22, 23). The side rails (22, 23) have such shapes as to provide a longer path (L1) for the air flow under one (22) of the side rails than an air flow path (L2) under the other (23) of the side rails when a direction of the air flow makes a skew angle ϑs relative to a center line (C) of the slider (21 ). The longer path (L1) extends from the corresponding tapered section (22a) at its upstream end to the recessed section (24) at its downstream end, while the air flow path (L2) under the other (23) of the side rails extends from the corresponding tapered section (23a) at its upstream end to outside of the slider (21) at its downstream end. The flying head slider (21) provides balanced positive pressures under the side rails (22, 23) to effectively prevent the rolling or inclination of the slider (21).
