Title: Formation of image
Inventor: YOSHINO YOSHIE
IPC: B41M5/398
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming an image by which the image is formed on an image-supporting body by a simple and inexpensive method by using a heat-sensitive adhesive. SOLUTION: The surface, on which an image is formed, of an image- supporting body 1 is heated selectively in accordance with the image to be formed at the temperature not lower than the temperature at which a heat- sensitive adhesive 2 shows stickiness by e.g. a thermal head or the like. A sticky latent image 3 having stickiness corresponding to a formed image is formed on the surface on which the image is formed. Then, a developer 4 such as toner is applied to the surface on which the image is formed. The sticky latent image 3 is developed by the developer A. Thereafter, the image depending on the developer 4a is obtained on the image-supporting body 1 by removing the image part, in other words, the developer excepting the developer 4a stuck to the part of the sticky latent image 3 on the image-supporting body 1.

Title: Anisotropic etchant of silicon and anisotropic etching of silicon
Inventor: SEKIMURA MASAYUKI
IPC: H01L21/308
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To enable highly accurate pattern formation without generation of any angled portion and use of etching mask having a compensation pattern by preparing for an anisotropic etchant of silicon by adding an interfacial active agent to alkali aqueous solution. SOLUTION: An anisotropic etchant of silicon is prepared by adding an surfactant to alkali aqueous solution. An etching rate at the (110) surface of single crystal silicon substrate formed by the anisotropic etchant including the interfacial active agent is reduced by one digit or more than that of the anisotropic etchant not adding the interfacial active agent. Therefore, progress of etching to the side surface (110) exposed in the anisotropic etching process of the (100) surface of the silicon substrate is remarkably controlled. Namely, backward progress toward the inside from the ridge of the side surface of the pattern exposed with progress of etching can be controlled. Thereby, missing of a part at the angled portion of the mask can be prevented and highly accurate pattern may be formed depending on the mask.

Title: Flow rate control valve
Inventor: SHIYOUJI MASANAO
IPC: F16K1/52
Filed: 1994-03-28
Abstract: PURPOSE:To control a flow rate accurately and finely with normal displacement of a valve shaft by forming one of abutting surfaces of a nozzle end surface and a sealing elastic body to be inclined surface. CONSTITUTION:When a valve shaft 4 is moved to a nozzle 1, a sealing packing 2 is in contact with first a portion 1a nearest an inclined end surface 1' of the nozzle 1, then with all of the end surface 1', for fully closing a flow passage 8 and interrupting the flow passage. When the valve shaft 4 is moved oppositely to the nozzle 1, a part on the end surface 1' of the flow passage 8 is opened and fluid passes therethrough. As the motion of the valve shaft 4, the packing 2 is gradually separated from a lowest portion 1b of the inclined end surface 1' of the nozzle 1. The opening of the flow passage 8 is gradually increased in respect to displacement of the valve shaft 4, so that a flow rate of the fluid is minutely varied corresponding to the displacement of the valve shaft 4. Accurate control of the flow rate is thus enabled.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To safely and inexpensively obtain the subject compound having characteristics excellent as an electron transporting agent by oxidizing a hydroquinone derivative with a carbonate of an alkali metal. SOLUTION: A hydroquinone derivative of formula I (R<1> is an alkyl or an aryl; R<2> is an alkyl, an alkoxy, an aryl or an aryloxy) is subjected to oxidation reaction in a solvent such as THF at 0-80 deg.C for 1-10hr by using a carbonate of an alkali metal, e.g. potassium carbonate to provide the objective naphthoquinone of formula II. The antioxidant is used in an amount which is equimolar to that of the compound of formula I or in slightly excess amount than the equimolar amount. Since the compound of formula I is hardly dissolved in water, the compound of formula I is preferably mixed and reacted with an aqueous solution of carbonate of an alkali metal in the presence of a water- soluble organic solvent. The carbonate of the alkali metal is inexpensive, compared with chloranil which has been used hitherto and can improve stability of reaction.

Title: Method and device for detecting damaged part of paint film of buried steel pipe
Inventor: FUJIMOTO KOJI
IPC: G01N27/24
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To detect the damaged position of a paint film in an underground buried pipe accurately and positively with a high sensitivity. SOLUTION: A signal generated by an M-series signal generator 10 is amplified by a power amplifier 3 and is applied between a buried steel pipe 1 and an installed electrode. A investigating machine 6 is run on a ground surface along the longer direction of the buried steel pipe 1 to detect a potential difference between wheel electrodes 6a and 6b. A reference signal with the same pattern as that of the signal from the M-series signal generator 10 is outputted from an M-series reference signal generator 11. The cross correlation between a potential difference between the wheel electrodes 6a and 6b and a reference signal is calculated by a correlation processing part, its peak value is adopted as the representative value of the potential difference, and an operation processing is made using the representative value, thus improving an S/N ratio drastically.
