Title: Molecular beam epitaxial growth method
Inventor: OGASAWARA KAZUTO
IPC: H01L21/203
Filed: 1985-12-17
Abstract: PURPOSE:To make both mixed crystal with its rate changed and mixed crystal at a fixed rate of constitution grow with superior reproducibility, by using a plurality of molecular beam source cells which are different in their volume to accommodate molecular beam materials consisting of aluminum. CONSTITUTION:Molecular beam source cells 3a, 3b, and 3c are made to be cells of 16cc in crucible volume, molecular beam source cell 3s being a small- sized cell of 5cc or so in crucible volume, with heating capacity of a heater being the same or so. Al molecular beam sources are stored in the large-sized molecular beam source cell 3 and the small-sized molecular beam source cell 3s by the use of such a growth device, and heating fusion are performed. In case that crystal of fixed constitution is made to grow, Al is made to evaporate from the large-sized molecular beam source cell 3c. In case that crystal with is mixed crystal rate being changed is made to grow, Al is made to evaporate from the small-sized molecular beam source cell 3s to control the heating amount of the heater in the molecular beam source cell 3s. Thus, superior following property to a constitutional change improves reproducibility in growth of a mixed crystal layer.

Title: Magnetic recording medium
Inventor: FUJII SHIGEO
IPC: G11B5/66
Filed: 1989-10-30
Abstract: PURPOSE:To obtain a medium having little warpage and suitable for high-density recording by providing head layers of <=12mum thickness on both sides of a substrate base in a manner that thickness of two layers differs by <=0.5mum. CONSTITUTION:A hard layer of <=12mum thickness is provided on the front and back sides of a substrate based in a manner that difference of thickness between the hard layer on the front side and the hard layer on the back side is <=0.5mum. Deformation of a substrate on heating at high temp. is caused by thermal stress due to difference in thermal expansion between nonmagnetic hard layers and the substrate base. In order to reduce warpage of the substrate due to such deformation, it is effective to reduce the difference in film thickness for both nonmagnetic hard layers provided on the substrate base. The hard layers are made <=12mum thick, considering the production efficiency. If the hard layers are made >=12mum thick, influence of the difference in film thickness becomes little. Thereby, deformation of the substrate can be avoided even when the substrate is heated in the process of film forming. The obtd. medium can be used for a low floating-type magnetic head.

Abstract: PURPOSE:To remove the occurrence of no-load injection by a structure wherein a controlling unit, which controls so as to bring a material feeding device to the stop state, when the remainder of the number of moldable products from the specified number of products to mold reaches the predetermined value. CONSTITUTION:Firstly, molding is done by using molding material 4 in a hopper 10 under the state that both suction blowers 5 and 9 are put into actuation. A main controlling device 18 calculates how many more products can be molded by the material 4, which is supplied to the cylinder part 14 of an injection molder and, in addition, left in a hopper 10 and in a drying device 7, on the basis of data, which are fetched from the memory of the main controlling device 18, such as the number of a hopper in use, the specific gravity of material, the standard weight of product, the volume of the cylinder of the injection molder and the like and sends the calculated result to a controller 15. The controller 15 compares the present yield sent from a product counting device 17 with the number of products to mold sent from the main controlling device 18 so as to stop the actuations of the blowers 5 and 9 when the remainder of the present yield from the number of products to mold reaches the predetermined value. The molding after the stop of the blowers 5 and 9 is done only by the molding material 4 left. When the target number of production is reached, the controller 15 puts the suction blowers 6 and 9 into actuation so as to charge molding material 3 from a material bag 1 into the cylinder part 14. Accordingly, the occurrence of no-load injection can be removed.

Title: Device and method for processing picture
Inventor: MURAKAMI TATSUYA
IPC: H04N1/40
Filed: 1990-10-24
Abstract: PURPOSE:To prevent the deterioration of the picture quality of the output picture of a picture processor by folding up plural filters of different bands and dither pictures and selecting the filters from the pattern feature of the dither picture in a reference window, and then, selecting one out of plural intermediate tone outputs calculated by using the plural filters on the basis of the selected result of the filter. CONSTITUTION:Multi-level picture data are calculated at every picture element by calculating sum of products of filters in accordance with a nearby dither picture and visual characteristic of human beings. When the frequency of occurrence of black-and-white picture elements is extremely biased, granular noise generating points can be suppressed by switching the coefficient of a filter in accordance with the distributed state of black and white. The switching of the coefficient can be performed effectively with a simple constitution by using the number of white picture elements in a window referred to at the time of reproducing an intermediated tone picture. Therefore, highquality output pictures are obtained irrespective of the dither system performed at the time of binarization.
