Title: Fuel feed controller of gas turbine
Inventor: OZONO JIROU
IPC: F02C9/40
Filed: 1983-05-27
Abstract: PURPOSE:To enable fuel of gas turbine to be switched in a short time, by a method wherein a switch valve is controlled by means of a control valve opening instruction having a different value according to properties of two types of gas fuel, and the secondary pressure of a fuel control valve is balanced with a pressure in a burner. CONSTITUTION:Since the heating value of LNG is different form that of LPG, a minimum fuel instruction signal 16 is sent to gain converters 40 and 41, and thereafter, it is sent to each of fuel valve position control circuits 18-1 and 18-2 . The constant of the gain converter 42 takes the form of the characteristic ratio of each fuel, and during switching, the sum of input signals is equal to the out put signal of a low value preference circuit l7. The secondary side of a fuel control valve 15-2 is brought to a negative pressure as against a pressure in a burner 4 thanks to a spray effect. Thus, a differential pressure detector 45 detects a differential pressure between a secondary pressure and a discharge pressure, and generates bias until the difference enables feed of the fuel to a burner. This permits the one fuel system to be switched to the other in a short time.

Title: Sic roller for roller hearth furnace
Inventor: SATO AKIHIKO
IPC: F27B9/24
Filed: 1995-03-16
Abstract: PURPOSE: To obtain a SiC roller for a roller hearth furnace capable of being used at a considerably high temperature and having a less-sticky surface by making the SiC roller of reaction sintered SiC having a specified porosity, a specified bulk specific gravity and a specified free Si amount. CONSTITUTION: A SiC roller for a roller hearth furnace is made of reaction sintered SiC having a porosity of 5% or less, a bulk specific gravity of 2.95 or higher and a flee Si content of 3% or less. In order to reduce the free Si content without lowering the bulk specific gravity and the porosity, sufficient formation of secondary SiC is necessary. A graphite powder having sizes of about 10μm is used as C for a starting material. A compounding ratio of SiC to C is approximately 3 to 1. If the density of a compact is too high, injection of Si becomes difficult, and if the density of the compact is too low, the bulk specific gravity finally becomes small. Si injection and silicification are carried out as quickly as possible. Raw materials are sufficiently kneaded and the compact is produced by exercising care to these points.

Title: Current limiting reactor
Inventor: ARINOBU HIROYUKI
IPC: H01F7/16
Filed: 1982-05-31
Abstract: PURPOSE:To easily make a reactor adaptable to various rated currents such that the impedance is reduced during feeding of the rated current and increased at the time of occurrence of an excessive current, by a construction wherein a plunger is disposed in front of a coil bobbin and held by a latch, and the plunger is attracted to be released from the latch by the magnetic force of a coil when the excessive current occurs. CONSTITUTION:A current limiting reactor is connected in series to wiring lines (not shown) through a terminal unit 19, and a coil 8 serves as an electric line element. The illustrated state represents the normal state where the rated current is fed. At the time, since the resilient force of a latch spring 22 overcomes the total sum of the attraction force of the coil 8 for attracting a plunger 22 and the resilient force of a coil spring 28, the plunger 22 is held out of the coil 8. Thus, the current limiting reactor has an impedance value based on the hollow coil. This makes it possible to set the impedance relatively small for feeding of the rated current.
