Inventor: MIKAMI HISAFUMI
IPC: B21B1/26
Filed: 1992-09-10
Abstract: PURPOSE:To increase the production capability of a hot rolling mill and reduce the scale biting flaw of a stainless steel sheet by using graphite crystallization rolls and high-speed steel rolls for work rolls in the prestage and poststage of a finishing mill and optimizing the load distribution to each stand of a rolling mill in a hot rolling line. CONSTITUTION:Rolling is executed by using high chromium cast iron rolls for F1-F3, high alloy grain rolls for F4-F6 and making the load distribution to the finishing mill and the steel sheet temp. on the outlet side of the roughing mill the same conditions. Further, rolling is executed by using the graphite crystallization rolls for F2 and F3, the same work rolls as a conventional method for other mills and making the load distribution to the finishing mill and the steel sheet temp. on the outlet side of the roughing mill the same conditions. Consequently, the scale biting flaw of the ferritic stainless steel sheet is reduced without decreasing the production capability of hot rolling. This method contributes to the reduction/preventation or repeat of the pickling treatment of the hot rolled sheet of the ferritic stainless steel sheet and the reduction of the cost of pickling.

Title: Method and apparatus for treating water containing boron
Inventor: AKEGA HARUKI
IPC: C02F1/42
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To enable a process in which boron is removed efficiently even in large scale water treatment with an adequate removal percentage maintained. SOLUTION: Water containing boron is introduced into a pH adjusting tank 10 to be mixed with an alkaline agent to adjust pH at 8.5 or more. In this way, most of boron in water is dissociated in the form of B(OH)4 . In a reverse osmosis(RO) membrane apparatus 12, the dissociated boron is removed. Moreover, water which passed through a reverse osmosis membrane is introduced into a boron selective ion exchange resin column 14, where residual boron is absorbed to be removed. Alkaline waste liquid generated in the regeneration of the boron selective ion exchange resin is reused for an alkaline agent which is added in the pH adjusting tank 10.

Title: Electric reduction gear for driving shield cutter and electric reduction gear
Inventor: YOICHI SHIYOUJI
IPC: E21D9/087
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of torque transmitted to a cutter face by forming the relation of a slide speed and a friction coefficient between clutch plates in such a way that the slide speed is above a fixed slide speed and the friction coefficient is constant or rises slightly. SOLUTION: An electric reduction gear for driving shield cutter X decelerates an output of an electric motor 1 by a planetary reduction gear mechanism 2 to rotate and drive a cutter face 52 from an output shaft 4. The planetary reduction gear mechanism 2 decelerates at three steps by sun gears 13, 18, 23 and a plurality of planetary gears at outer periphery thereof 14, 19, 24. The electric reduction gear X itself is made compact by assembling a wet hydraulic clutch plate 3 in the planetary reduction gear mechanism 2 integrally and arranging it in a case main body 9. A friction plate 31 is made of a material having a high friction coefficient or static friction coefficient close to it.  When slide occurs while a steel plate 30 and the friction plate 31 are in pressure-contact, it is possible to drive the cutter face 52 without reducing transmission torque even if a clutch plate 32 begins to slide.

Title: Temperature correction circuit for ultrasonic length measuring system
Inventor: NOUMI YUUZOU
IPC: G01S7/52
Filed: 1984-11-17
Abstract: PURPOSE:To achieve accurate temperature correction, by connecting a temperature measuring resistor to one input of a differential amplification circuit while a cable length correction circuit is connected to the other input thereof to correct errors due to the resistance of a cable used in the connection of the temperature measuring resistor. CONSTITUTION:The speed of sound in air changes with the temperature and will differ in the measured value even in the measurement at the same length, unavoidably causing errors. To solve this, a temperature measuring resistor Rpt is selected in such a manner that the resistance temperature variation rate will be equal in the ratio to the temperature variation rate in the speed of sound in air to automatically cancel changes in the speed of sound due to the temperature. Moreover, a cable length correction circuit EV is provided and hence, the reference voltage EX2 can be set variably to match the cable length thereby enabling correct temperature correction along with flexible adaption to any cable length.

Title: Combustor for gas turbine
Inventor: BANDAI SHIGEMI
IPC: F02C7/18
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To decrease an NOx exhaust amount and to suppress fuel vibration, by providing air holes at a peripheral wall of a combustion chamber to an upstream, and constituting to supply the air from the holes to the vicinity of the wall. SOLUTION: A peripheral wall (steam cooling wall 2) of the combustor 7 is upgraded. That is, a plurality of air holes are opened along a circumferential direction at the wall of the combustor 7, i.e., an upstream side site of the wall 2 or a site of a main nozzle 3 to an outside. Since the air is supplied from a plurality of the air holes opened at the wall 2 in a low velocity region, this dilute air forms a film flow in the region, and rise in fuel concentration of such a site is suppressed by the flow. Thus, propagation of a flame 5 developed from a center of a combustion chamber 10 to the upstream side is prevented. Then, rise of combustion temperature due to the propagation of the flame 5 is suppressed. NOx exhaust amount is reduced, and, generation of combustion vibration due to abrupt rises in combustion pressure and temperature is avoided.

Title: Pressurized fluidized bed boiler
Inventor: MIZUMOTO MAMORU
IPC: F23C10/16
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To increase a velocity of desulfurization reaction by a method wherein a fuel nozzle is arranged upward in relation to the horizontal direction. SOLUTION: The height of a fuel outlet is positioned just in the middle between an air dispersion plate 12 and the lowest stage of a heat transfer pipe 15. Particles in a furnace are made to have a sufficiently upward speed and dispersion of fuel is smoothed. The injection direction of a fuel nozzle 51 is arranged upward, for example, by 10 deg. with a horizontal plane. As a result, height at which mixture with combustion air fed from a furnace bottom is effected is situated in a position higher than that of the tip of a nozzle 51. A region of a low CO2 partial pressure is spread upward by an amount equivalent to height higher than that of the tip of the nozzle and a residence time in which a limestone resides in a region of a low CO2 partial pressure is increased.  This constitution advances decarboxylation reaction of the limestone, forms fine holes after CO2 goes out, and increases the surface area of the limestone. The partially decarboxylated limestone is moved to a region wherein coal starts combustion reaction and react with SO2 generated by combustion to advance desulfurization reaction.

When the steel bar 1 stops travelling, with the ascending of a braking plate 28, transfer of take-in traverser 22 shifts the steel bar 1 onto a straightening floor 32.

Abstract: PURPOSE:To control temperature in a cavity locally in a short period of time and prevent a molded form from generating deformation, crack or the like, by a method wherein a magnetic body, constituting the cavity of a mold, is equipped with a temperature detector and a temperature control mechanism. CONSTITUTION:Molds are opened and a mold temperature regulator 17 is operated by a sequencer 24 to start the rising of the surface temperature of the cavity of a mold 10. Eddy current is generated in the magnetic bodies 11a-11d of the cavity by electromagnetic induction whereby Joule's heat is generated and only the magnetic bodies 11a-11d are heated. When the surface temperature of the cavity has arrived at a set temperature Test, the molds are closed and injection process is started. During this period, the surface temperature of the cavity is held at a set value by a control mechanism. After finishing the injection process, the conduction of high frequency wave is stopped by the command of the sequencer 24 and cooling water is introduced into the mold 10 by a mold cooling water supply on-off valve 25. Heating and cooling can be controlled quickly in only a part of the cavity whereby a molding time may be shortened and the deformation or the like of a molded form due to faulty cooling may be prevented.
