Title: Thermocouple protective tube
Inventor: KIMURA ETSUJI
IPC: C04B38/00
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To obtain a protective tube whose thermal shock resistance is excellent by a method wherein the grain boundary of magnesium oxide particles is provided with a texture in which magnesium titanate generated by a reaction with titanium oxide is interposed and a true porosity is set at a specific value. SOLUTION: A raw material powder which contains 90 to 80wt.% of magnesium oxide and 10 to 20wt.% of titanium oxide is fired, and magnesium orthotitanate generated by a reaction with the totanium oxide is interposed in the grain boundary of magnesium oxide particles. Thereby, when a protective tube comes into contact with a high-temperature basic molten body, it is possible to effectively prevent the molten body from being permeated into the grain boundary, and its excellent corrosion resistance is displayed with reference to the basic molten body which contains especially iron. In addition, its ture porosity is set at about 5 to 15%, its thermal shock resistance is held, and its permeability is suppressed.  In order to obtain the true porosity, a raw material powder in a particle size of about 1 to 500μm is compressed under a press pressure of about 1200 to 2000kgf/cm<2> , and it is fired at a temperature of about 1450 to 1550 deg.C. In this manner, it is possible to obtain the protective tube whose thermal shock resistance is excellent and whose corrosion resistance and permeability resistance are good.

Abstract: PURPOSE:To evade the generation of a pseudo synchronization even against a special signal string by varying a delay time of a variable length delaying circuit and executing an error detection by a bit collation, selecting the minimum delay time by a bit error quantity and executing the bit collation. CONSTITUTION:An input signal 9 is inputted to a decoding circuit 3 through an encoding circuit 1 and a transmission line 2, and a signal 10 is outputted, and also, inputted to an input/output signal supervisor circuit 12 through a decoding circuit 4. The circuit 12 compares output signals of the circuit 3 and the output 4 at every bit and executes error supervision. That is, the output signal of the circuit 4 is inputted to a bit comparing circuit 5 through a variable length delaying circuit 6, and compared with the output signal 10 of the circuit 3 at every bit. Also, the bit comparison is executed by changing a delay time of the circuit 6, and this delay time and a result of comparison of the circuit 5 are stored in a storage circuit 7 together with its relation. Subsequently, an optimum delay time deciding circuit 8 selects the case when a bit error quantity is minimum in the storage contents of the circuit 7, sets a delay time of this time to the circuit 6 and executes a bit collation, therefore, the generation of a pseudo synchronization can be evaded.

Title: Control method for batch type incinerator and batch type incinerator
Inventor: WAKAZONO KOSHI
IPC: F23G5/50
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of smoke, in a batch type incinerator. SOLUTION: A computer 250 inputs a fuzzy inference input at S910 and operation amounts of air amount regulating valves V1-V5 are calculated through fuzzy inference and outputted as a command value at S920. The command value is the increase and decrease value of the opening of the air amount regulation valve V3 when, for example, three air amount regulation valves V1, V2, and V3 are an object to be controlled. When the opening of the air amount regulation valve V3 is increased, the opening of the air amount regulation valve V1 is decreased. Since a blast height at which the change in a furnace temperature T is reduced corresponds to the height of an upper combustion surface, by effecting blast to the height, complete combustion is continued at the upper combustion surface and the generation of smoke is prevented from occurring.
