Title: Liquid eraser
Inventor: KATO AKIMITSU
IPC: C09D10/00
Filed: 1991-02-27
Abstract: PURPOSE:To obtain a liquid eraser which can give an area to be corrected to which one can give a writing with a water base ink without causing the shrinkage, a reduction in the density, etc., of the writing by mixing a hiding material with an organic solvent and a specified elastomer. CONSTITUTION:A liquid eraser is produced by mixing a hiding material (e.g. titanium oxide) with an organic solvent (e.g. toluene) and a styrene/isoprene/ styrene block copolymer elastomer as essential components. This elastomer is used in order to form a coating film which can prevent a writing from undergoing a reduction in the density and is added in an amount of desirably 5-20wt.% based on the total amount of the eraser. In order to improve the hardness of the coating film, the dispersion stability of the hiding material, etc., it is also possible to use also another resin such as an acrylic resin or a polyester resin. By using magnesium oxide or the like together, the effect of preventing color settlement can be further improved.

Title: Substrate drying-equipment and operation method therefor
Inventor: KAWASAKI KIYOHIRO
IPC: H01L21/304
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To completely dry a thin large area substrate, without breaking it. SOLUTION: A substrate 40 is transferred into a drying vessel 41 which can be sealed aritightly, the substrate is left being tilted or placed almost vertically, and the drying vessel 41 is purged by an inert gas. The drying vessel 41 is filled with quick-drying solvent vapor to bedew the substrate 40, the water droplets on the substrate 40 are removed by replacement, the solvent vapor is ejected after being evaporated under a depressurized condition in the drying vessel 41, and the substrate 40 is dried. In this way, since the substrate 40 is not spin-dried at a high speed, unnecessary force is not applied so that the substrate 40 is not broken. As the combustible solvent and its vapor are used in the drying vessel 41 which can be airtightly sealed, ignition is prevented.

Title: Temperature control device for direct electrical heating type salt bath furnace
Inventor: OOHASHI KAZUHIRO
IPC: C21D1/46
Filed: 1984-03-28
Abstract: PURPOSE:To provide a titled temp. control device which measures and controls furnace temp. by a method having reliability and durability by combining the output signal of a meter relay type ammeter, a repeated conduction signal for limiting time, a power source switch and the latching contacts of the power source switch. CONSTITUTION:A power source switch 4 operates to pass heating current to a salt furnace 1 when said furnace is set in the heating up state for ordinary use of the salt bath furnace and when the conducting contacts T.a for limiting time of a timer 9 are conducted by said timer. If the current is smaller then the set current value of a meter relay type ammeter 7, the control output contacts C, L are conducting and therefore the heating current continues to flow as it is to the furnace 1. The pointer of the ammeter 7 exceeds the set current value if the heating current increases upon increasing of the temp. in the furnace 1. The switch 4 is interrupted when the contacts C, L of the ammeter 7 open at the same instant as said increase, then no more heating current flows. The current of the furnace 1 is thereafter automatically maintained within a specified range (during operation of M.S) by the control to trigger the signal of the timer 9 in the above-mentioned way.

Title: Manufacture of semiconductor integrated circuit device
Inventor: OWADA NOBUO
IPC: H01L21/3205
Filed: 1987-03-16
Abstract: PURPOSE:To obtain the flat surface of an insulating film by a method wherein a surface flattening to be formed by etching back is effectively performed utilizing a fact that when a sputter etching is performed on the stepped surface of a base, the inclined part is preferentially etched at speed about several times faster or more compared to the flat part. CONSTITUTION:Wirings 31 and 32 are formed on an insulating film 2 formed on the surface of a semiconductor substrate 1 and thereafter, an insulating film 4 is formed on the whole surface by a plasma CVD method and a normal pressure CVD method, for example. In case the aspect ratio (the depth of a groove/the width of the groove) of a groove 5 between the wirings 31 and 32 is large, an overhang part 4a is formed in the film 4. The overhang part 4a having a steep inclination is preferentially etched to the flat part. The film 4 is formed into the same good form as that in case the aspect ratio of this groove 5 is small even in the interior of the groove 5. After an insulating film 6 is formed on the whole surface, a coat film 7 is formed on the whole surface. The film 7 and the films 4 and 6 are etched back until the surfaces of the wirings 31 and 32, for example, are exposed by reactive ion etching (RIE), for example, on such conditions that the etching rates of the film 7 and the films 4 and 7 become equal.

IPC: G01S13/60
Filed: 1993-03-18
Abstract: PURPOSE:To provide an on-vehicle radar which can detect presence of a vehicle positively even when a narrow obstacle is present in the front. CONSTITUTION:Continuous wave transmitted from a continuous wave transmitter 11 and radiated from an antenna 12 is reflected on a forward obstacle and received by the antenna. The reflected wave is subjected to frequency conversion by a mixer 13 using a reference wave transmitted from a reference wave transmitter 14 and then analyzed by a frequency analyzing means 15 thus extracting information relevant to the distance between vehicles, the relative speed, the moving direction of obstacle, etc. The information is presented on a display means 16. A control means 17 controls a driving means 18 for scanning the antenna in the direction to the right and left as well as the frequency analyzing means. Since the antenna is scanned in the direction the right and left, even an obstacle present at the dead angle of antenna can be detected positively.

Abstract: PROBLEM TO BE SOLVED: To facilitate the adjustment of the mount position of a CCD by using image data which are obtained by correcting image data of paper read by the CCD by the amount of deviation in CCD light receiving line for the output of a reader. SOLUTION: For the setting of a read data correction value, a paper read section 1 reads the test chart of image data, the data are stored in a data storage section 2, then coordinates of four corners of the test chart are calculated to decide whether or not there is any meandering feed, when no oblique feed is in existence, whether or not a CCD light receiving line is normal is decided, when normal, a correction setting section 3 sets the setting value to zero, and the result is stored in a correction value storage section 4, and when not normal, a correction value calculated by a correction setting section 3 is stored in the correction value storage section 4. On the other hand, for the correction of read data, the read section 1 reads the image of paper, and the data are stored in the data storage section 2.  Then a data correction section 5 corrects all the read data stored in the memory based on the correction value in an opposite direction to the subscanning direction. Then the corrected read data are outputted from the section 5.

Title: Molding of synthetic resin product with thin wall part
Inventor: YASUI MASAAKI
IPC: B29C45/56
Filed: 1985-03-22
Abstract: PURPOSE:To enable to smoothly fill resin to thin wall part molding portions by a method wherein thin wall parts are formed by shifting a movable mold after molten resin is fed and filled in a mold. CONSTITUTION:Molten resin is fed under pressure in a mold, which is put under the state that a sliding core 7 forming some part of the molding surface of a space molding portion 1 is retreated through a piston shaft 9 by means of a hydraulic cylinder 8 so as to widen thin wall part molding portions 1a. The molten resin smoothly fills square wave form space part 1a, which is a wide flow passage. After that, at proper timing, the sliding core 7 is advanced so as to form the thin wall parts of the predetermined hinged parts. In addition, because the sliding core is advanced under pressure, the surfaces contacting with the molding surface become smoother, resulting in obtaining a product with excellent quality.
