Title: Steam turbine for quick start
Inventor: SHIMAKITA MASATOSHI
IPC: F01D25/20
Filed: 1985-10-29
Abstract: PURPOSE:To keep a turbine rotor at a high temperature and shorten the starting time in the DSS (Daily Start & Stop) operation, even when a steam turbine is at rest, by supplying pyrogenetic lubricating oil to a turbine rotor bearing and introducing the pyrogenetic steam into a shaft sealing part. CONSTITUTION:A steam introducing hole 11, which is connected to a connecting hole 13 that is provided in a labyrinth seal 14, is made in a dummy seal 2, and moreover the steam introducing hole 11 is connected to a steam pipe 12 which is led to a high temperature steam supplying equipment. On the other hand, the drain oil from a bearing 7 supporting a rotor 1 is sucked from a suction pipe 21 by means of an oil pump 22 and is supplied to an oil filler port 25 of the bearing 7 via a heater 23. With this contrivance, when the turbine is at rest, the pyrogenetic steam is blown into a casing from the dummy seal 2, while the lubricating oil, which is heated by the heater 23 having a circulating heating-medium, is supplied to the bearing 7. Accordingly, the turbine rotor 1 can be kept at a high temperature even when it is at rest, and at the same time the starting time in the DSS operation can be shortened.

Filed: 1987-09-29
Abstract: PURPOSE:To simplify the manufacture of bi-layer glass by lapping together a glass plate and a polyurethane film, putting it into an air-tight flexible bag, discharging the air from the bag and heating it. CONSTITUTION:Ordinary plate glass, floating glass, heat rays absorbing glass or the like can be used as a glass plate, and for the polyurethane film it is preferable that the exposed surface of the said film has a self-restorativeness and also stainproof, mar-proof, wear-resistant, chemical-resistant surface properties. As the said bag, an air-tight flexible bag is used, such as rubber bag, polyethylene film bag, nylon film bag and the like, the glass plate and the polyurethane film are lapped together, and this lapped object is put into the bag and the bag is degassed. In this case, it is possible to degas effectively by keeping this object at a temperature below 10 deg.C. In the state that the bag is degassed, the lapped object is heated in the range of 15-50 deg.C. As a result, the work for manufacturing can be remarkably simplified.

Title: Image forming device
Inventor: NAGASE HISAYOSHI
IPC: G03G15/00
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent both-surface image extending over a long term by excellently eliminating toner left on an intermediate transfer body as an image forming device constituted so that a toner image formed on an image forming body is formed at both surfaces of a transfer material through the intermediate transfer body.

Title: Code information reader
Inventor: KUBOTA KAZUHIRO
IPC: G06K7/10
Filed: 1991-09-24
Abstract: PURPOSE:To prevent the frequent occurrence of a read defect by providing a read range control means which freely variably controls at least one of the intensity of light of scanning light made incident on a light reception part and the light reception sensitivity of the light reception part. CONSTITUTION:In a bar code scanner 9, an optical filter 10 is rotated to change light transmission parts 11 to 14 placed on the optical path, and thereby, the intensity of light made incident on an optical sensor is varied to control the read range of the bar code. For example, if even bar codes of commodities piled up in a basket or bar codes of commodities on adjacent sacker bases are read and scanned because of the excessive read range, the optical filter 10 is rotated to put light transmission parts 12 to 14 having a low transmittance on the optical path. If a read defect of the bar code of the commodity on a light-transmissive window 7 frequently occurs because of too small read range, the optical filter 10 is rotated to put light transmission part 11 to 13 having a high transmittance on the optical path. Thus, the bar code read range is satrsfactorily controlled in accordance with various conditions.

Filed: 1990-09-13
Abstract: PURPOSE:To achieve improvement of thermal responsiveness by a method wherein a compound to be expressed by a specific formula is contained in a thermal recording material containing a dye precursor and an electron acceptive compound. CONSTITUTION:A thermal recording material which is excellent in thermal responsiveness and high in coloring density can be obtained by containing a compound to be expressed by the formula (I) in the thermal recording material containing a colorless or light colored dye precursor and an electron acceptive compound (developer) which colors said dye precursor by reaction in heating. In the formula, however, X, Y represent an oxygen or a sulfur atom and it is allowed that both may be same or different with each other. Further, Z represents a 2 or more C alkylene radical which may have a side chain of an alkyl radical, and R represents a lower alkyl radical. For this compound, a cyclic acetal or a cyclic dithioacetal can be obtained by reacting, for example, ethanedithiol by using a normal acid catalyst. In that case, reaction with diol is generally performed while water is being removed.

Title: Optical fiber cable
Inventor: SAITO SHIN
IPC: G02B6/44
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To make optical fiber tape conductors into cables, to thin and lighten the optical cable and to reduce cost by making structure that the optical fiber tape conductors are adjusted at the periphery of a center material. SOLUTION: The optical fiber tape conductors 3 are twisted at the periphery of the center member 6 constituted by a tension member 1 and a coated layer 2, and a protection layer 4 and a seath 5 are sequentially formed on the outer periphery. Since the tape conductors have simple structure and they are made into the cables, the light optical cable whose diameter is thin can be obtained and installation becomes easy. Furthermore, manufacture is easy and therefore manufacturing cost is low. Since an expensive member is not used, material cost can be reduced.  When it is assumed that the layer center radius of the optical fiber cable is (a), a cable radius is A and the upper limit of the permission range of distortion occurred in the optical fiber when the optical fiber cable is bent by a winding radius (r) is σ, it is preferable to design the layer center (a) to be smaller than a value satisfying σ=a/(r+A).
