Inventor: TAKAHASHI SEIICHI
IPC: H01L21/3065
Filed: 1990-07-27
Abstract: PURPOSE:To obtain a high relative accuracy and an absolute accuracy in case a polycrystalline semiconductor layer is used for the formation of a resistance element by a method wherein parts, which are situated on the side surfaces of step parts on a semiconductor substrate, of the polycrystalline semiconductor layer are previously removed. CONSTITUTION:An anisotropic dry etching is performed to remove an oxide film on the surface of a polycrystalline silicon layer. At this time, the oxide film 109 on the side surfaces of parts, which cover gate electrodes, of the polycrystalline silicon layer is left. Subsequently, a thin film layer 110 consisting of transition metal element, such as tungsten, molybdenum or the like, or the like or a substance having a selection ratio with respect to etching with silicon oxide and polycrystalline silicon, such as tungsten, is selectively grown on the polycrystalline silicon layer. Then, after the film 109 is removed with a hydrofluoric acid, parts, which are situated on the side surfaces of the gate electrodes, of the polycrystalline silicon layer are removed using the mixed aqueous solution of a hydrofluoric acid, a nitric acid and an iodine-containing glacial acetic acid. Subsequently, after the tungsten thin film layer 109 is removed using the mixed solution of ammonia water and hydrogen peroxide water, a photoresist 111 is formed into a desired form by a photolithography technique and an anisotropic dry etching is performed using this photoresist 111 as a masking material to form a resistance element 112.

IPC: H03K3/023
Filed: 1987-08-12
Abstract: PURPOSE:To facilitate the high circuit integration by mounting externally for a resistor and a capacitor for charging purpose to an IC chip so as to attain a time shift time adjustment. CONSTITUTION:The resistor 12 and the capacitor 11 for charging are connected in series between a power supply 1 and ground and mounted (4) externally to an IC (integrated circuit).

Title: Image edit device
Inventor: ANZAI TOYOHIKO
IPC: H04N1/387
Filed: 1994-08-25
Abstract: PURPOSE: To relieve the burden of the operator and to improve the productivity by selecting automatically an optimum edit pattern. CONSTITUTION: When the operator uses a touch switch 10 to command a routine edit mode, at first an image input terminal 1 reads a slip (image) in an original and an image processing system 2 adjusts the density and magnification or the like. The image data are stored in an image memory 3. A CPU 11 detects the external frame of a slip in the original with respect to image data stored in the image memory 3 to secure the position of an area to be edited. Then only an area of a column is fed to an image output terminal 5, in which the data are printed out according to a description form of the slip and its column commanded by the operator. Since the position of the slip is decided by detecting the external frame of the slip in the original, when the original is placed on a platen glass, it is not required to set the original to an accurate position or a preset position.

Abstract: PURPOSE:To prevent a parison from being partially oriented in a spot in the proximity of a pinch part and to obtain a blow-molded product with no un-uniform thickness, by a method wherein a prepinched parison is positively fed into a mold, and a mold is closed so that a rubber balloon is crushed at the inside of the mold. CONSTITUTION:A rod 20 is protruded through feed of compressed air to a piston, a block 11 is maintained in a horizontal manner, and through feed of compressed air to a cylinder 12 as well, a rod, whereto pinch bars 17 are attached, is projected to a stroke end by a piston 14. When molds 2 and 3 approach, the pinch bars 17 move backward in a condition to nip a parison 5 between the bars 17, and a given amount of air is contained at the inside of the parison 5. When the molds 2 and 3 further approach, a forward end of a collar 2 makes contact with a forward end of a cam plate 22 which, in turn, runs over the collar 21, and a lock 11 is turned downward centering around an axle 10. This causes tilting downward of the pinch bars 17, feeding of the parison into the mold, allows free installation, at the inside of the mold, of the parison so that a balloon is crushed with the advance of a mold-closing operation, which results in obtaining a blow-molded product with the minimum of an uneven thickness.
