Title: Apparatus for applying resist
Inventor: SUGAWARA ICHIRO
IPC: H01L21/027
Filed: 1987-01-22
Abstract: PURPOSE:To prevent the resist from splashing back by providing another opening concentrically with the center opening in the upper part of the exhaust cup. CONSTITUTION:An exhaust cup 4 has another opening concentrically with the opening in the center of the upper part of the cup 4 to prevent the turbulence of the air stream in the cup 4 at the exhaust time, and also has a guide 3 for intake of external air in order to prevent the fly-out of mist from this part from going to the central opening side. A wafer 5 attracted to a spin chuck 2 shakes off the excessive resist by a high-speed rotation after the coating of resist. At this time, the shaken resist impinges on the inner wall of the cup 4 due to a centrifugal force and flies away in a mist, but if a forced exhaust is performed from the lower part of the cup 4, the external air is taken in also from the outside opening in the upper part of the cup 4, so that the mist is exhausted in an air stream condition of less turbulence. With this, the splashing back of the resist to the wafer surface can be prevented.

Title: Picture processor
Inventor: KAWAMURA NAOTO
IPC: G06T3/00
Filed: 1987-01-26
Abstract: PURPOSE:To reduce the capacity of a mask memory by transforming a mask pattern into codes. CONSTITUTION:The mask codes obtained by a coding means are stored in a mask memory. Then the picture information stored in a picture memory is segmented by a selection means based on a mask pattern decoded by a decoding means and outputted to a prescribed output device via an output means. For instance, a mask pattern consisting of a (4X4)-matrix is coded and compressed. When the mask pattern is stored in a mask memory 42, the codes converted into 7 bits by a look-up table are stored. While the binary signals converted into a (4X4)-pattern by the look-up table are outputted when the mask pattern is outputted to a synthesizer 34. Thus it is possible to reduce the capacity of a memory which stores the mask information on segmentation of pictures.

Abstract: PURPOSE:To obtain a new anisotropic magnet, by aligning the [001] axes of the individual tau phase fine crystals in an Mn-Al-C polycrystalline magnet to a given  direction parallel with a specific plane of the magnet preferentially in comparison  with the vertical direction to the said plane. CONSTITUTION:An Mn-Al-C alloy with a composition of, say, 68-73wt% of Mn, (1/10Mn-6.6)-(1/3Mn-22.2)wt% of C and balance of Al, is extruded to form a homogeneous fine [001] fiber structure of a single axis, and this is subjected  to a heat compression work along the axis direction thereof. In other words, after a  positive plastic strain is macroscopically given, a negative plastic strain is given.  Then a magnet is formed symmetrically to the axis thereof, which is magnetized on  its outer circuit. Then in a plane vertical to the symmetrical axis Z the magnetic  paths are formed, which bend to the direction of the radius around the poles and  bend to the direction of the outer circuit in the intermediary position. Thus a new anisotropic magnet having a great magnetism to all directions within plane can be  obtained.

Abstract: PURPOSE:To recognize the three-dimensional positions of driver's eyes in a cabin, by providing a light emitting means, two two-dimensional image sensor parts, which detect reflected light as pictures, and a means, which recognize the positions of the driver's eyes. CONSTITUTION:Infrared rays are projected on an area including the upper half part of a driver by using an infrared-ray stroboscope 5. The reflected light is detected by two two-dimensional solid-state image sensor elements (two-dimensional CCD) 9a and 9b. Then the picture processing is performed by an electronic operation circuit 20, e.g., the most closed white part, i.e., the special point of the center of the surface of the face is processed, and the part corresponding to the surface of the face is obtained from the picture of the driver. The central point of the area of the most closed white part is obtained as the special point. By using the average distance from the central point of the area to the position of the driver, the three-dimensional positions of the driver's eyes (the central position of both eyes) are recognized. Therefore the actual three-dimensional positions of the driver's eyes can be found without the effects of the noise and the like, and the angles of rearview mirrors can be automatically adjusted.

Title: Method and device for manufacturing extrusion-molded plate having uneven pattern
Inventor: KIDA MAKIO
IPC: B28B3/20
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent a raw plate from deforming after the forming of an uneven pattern, and form a lateral joint pattern of a high precision. SOLUTION: An endless embossing belt 41, on the surface of which a pattern is formed by an unevenness, is pressed to the surface of a raw plate 39 which is extruded from a mouthpiece 37, and thus, the uneven pattern of the endless embossing belt 41 is transferred to the surface of the raw plate 39 for the manufacture of an extrusion-molded plate having an uneven pattern. For such a manufacturing method, the raw plate 39 which is extruded from the mouthpiece 37, is fed while being pinched by the endless embossing belt 41 and a first endless carrying belt 47 which is driven while synchronizing with the endless embossing belt 41.  After cutting the raw plate 39 by a specified length in the extruding direction, on the first endless carrying belt 47, the raw plate 39 is transferred to a second endless carrying belt 55 which is driven while synchronizing with the first endless carrying belt 47. After the completion of the transfer, the second endless carrying belt 55 is driven at a driving speed which is faster than that of the first endless carrying belt 47, and the raw plate 39 is carried.

Title: Magnetic head working apparatus
Inventor: TAKESHITA KOUJI
IPC: B24B19/26
Filed: 1978-02-14
Abstract: PURPOSE:To enhance working accuracy and operating efficiency and achieve cost reduction by providing a means of machining the widths of tracks and cores and a means of measuring sizes without removing the sample and an image processing means of removing the adverse influences of vibrations. CONSTITUTION:When an expected working quantity is beforehand set and a table 2 is moved on the way of working at the machining with a grindstone, the widths of tracks and cores are positioned and the sample 3 is projected as an image 10 on a TV monitor 9 by way of a metal microscope 4, TV camera 6, camera controller 7 and TV controller 8. Hence, if the magnification on the monitor 9 is suitably changed over and the machining and size measurement are repeated, the widths of tracks and cores of high accuracy may be obtained without removing the sample from the table 2. If the magnification on the monitor becomes 2000 times or over or other, the vibrations from the working apparatus and the outside give adverse influences and therefore the still image 10 is obtained on the monitor 9 by a still image unit 11. Thereby, the working accuracy and operating efficiency may be enhanced and the cost reduced.

Abstract: PURPOSE:To divide a semiconductor wafer into each chip accurately and reliably at all times by setting a plurality of diamond-tipped diamond-cutters in an arrayed state in the direction of the movement. CONSTITUTION:The tip angle theta3 of a first diamond-cutter 11 and the tip angle theta4 of a second diamond-cutter 12 are first set to theta3>theta4, and a first scribing line 6a is made on a metal film 5a formed on a semiconductor wafer 4 by the first diamond-cutter 11. Then, a scribing line 6b is made by the second diamond-cutter 12 in the same position as the first scribing line 6a. In this instance, since the tip angle of the first diamond-cutter 11 and that of the second diamond-cutter 12 are set to theta3>theta4, and because the thickness of the metal film 5a has already become thin owing to the first scribing line 6a, strain 7 can be put into the semiconductor wafer 4 by making the second scribing line 6b.

IPC: G03F7/38
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a substrate heat-treating device which has an internal atmosphere having high temperature uniformity. SOLUTION: In first and second standby process, outside air flows in an enclosure, but does not reach the position of a substrate, because a shutter is closed while a cover is opened and, in a substrate delivery process, the outside air seldom flows in the enclosure and reaches the position of the substrate even when the substrate is received, because the exhaust is stopped while the cover and shutter are opened. Therefore, the temperature uniformity in the internal atmosphere of a substrate heat-treating device can be improved.
