Title: Flame detector for combustor
Inventor: TSUKAGOSHI KEIZO
IPC: F02C9/00
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctioning caused by the accumulation of ash in a flame detector which is used for a combustor for starting of a pressure fluidized bed compound power generation system. SOLUTION: A fuel nozzle 33 of a combustor for starting is mounted toward an inner cylinder 32 and a pipe 38 in a mounting pipe 36 is mounted communicating with the inside of the inner cylinder 32. A valve body 1 having a valve body path 1a communicating with the pipe 38 is connected to one end of the mounting pipe and a valve body 3 having a hollow 3a is connected to a shaft 2 within the valve body path 1a so as to be moved into or out of it. At the starting of the combustor, the shaft 2 is rotatably engaged with a shaft mounting part 3a of the valve body 3 while being screwed down on a thread part 6 of the valve body 1 to be moved to the right with the rotation of a handle 4 so that the valve body 3 is moved to open the path 1a. By the contrary, at the stopping of the combustor, the path 1a is closed by the valve body 3.  In the normal operation, ash is accumulated in the hollow 3a of the valve body 3 and there is no accumulation of the ash on a glass plate 37 at a lower part. Thus, the ash will not block function.

Title: Burner and incinerator for waste gas incineration
Inventor: UEMATSU KENGO
IPC: F23G7/06
Filed: 1981-08-20
Abstract: PURPOSE:To prevent the production of unburnt component, reduce the amount of NOx generated, and simplify the structure of an incinerator by such a construction that a second nozzle for supplying air is inserted coaxially inside a first nozzle for supplying waste gas. CONSTITUTION:A second nozzle 11 for supplying air is inserted coaxially inside a first nozzle 10 for supplying waste gas. With this construction, air enters the central part of a flame 12, and therefore, a combustion surface 13 spreads outwardly and expandedly. Thus, the flame 12 is shaped in a thick and short barrel form, which is expanded in the middle. Accordingly, the flame density and flame temperature are decreased uniformly over the flame, thereby decreasing the generation of unburnt component and NOx extremely. When this type of burner 22 is installed on the side wall 21 of the incinerator, it is preferable to arrange a waste gas supply passage 23 inside an air supply passage 24. This is because this structure can eliminate the need of provision of a number of additional pipes and thus simplify the structure of the incinerator.

Filed: 1986-06-05
Abstract: PURPOSE:To easily delete an unnecessary registered character string by recording the using frequency of the registered character string in a memory device and referring this using frequency to delete to an arbitrary character string. CONSTITUTION:At first, the threshold of the using frequency is inputted to the position of THRESHOLD. Then, the table of the registered character string in which the using frequency is below the threshold is outputted to a picture together with the using frequency. Then, a mark of R is added only to the character train which is not desired to be deleted. When the command of DELETE-ALL is inputted, all of the registered character string in which the using frequency is below the threshold except one having the mark R added are deleted. When the mark of D is applied only to the registered character train desired to be deleted and the command of the DELETE-EACH is inputted, only the character string is deleted from the registration. Further, after the DELETE, a reading is directly designated and the arbitrary character string can be deleted from the registration.

Filed: 1995-05-30
Abstract: PURPOSE: To provide a PLL circuit suitable for high speed transfer without increasing a circuit scale and power consumption. CONSTITUTION: Amplitude hold circuits 110-112 hold an amplitude value for comparing phases in a clock component incorporated in a regenerative signal in the vicinity of an identification non-signal, an identification signal 1, 0 by a sampling signal from an identification signal separation circuit 109. Amplitude distribution measurement circuits 113-118 measure the fluctuation amount of the amplitude value held at the timing of the leading phase or the logging phase for a sampling position. An identification distribution comparison circuit 123 judges whether the phase of an output clock of a voltage control oscillation circuit 125 is equal to a leading or lagging phase compared with the phase incorporated in the regenerative signal from the size of the fluctuation range of the amplitude obtained at every difference of the phase of the sampling signal by adder circuits 120-122.  A change pump circuit 124 is controlled based on the judgement, and the frequency of the output clock of the voltage control oscillation circuit 125 is controlled so that both phases matches each other.

Abstract: PURPOSE:To attain a desirably color-converted printing state by providing a means detecting black having minimum brightness and white having maximum brightness and a means converting black and white into a predetermined color by a CPU and color-converting only black having minimum brightness and white having maximum brightness on printing. CONSTITUTION:When a data read from a memory in a color hard copier represents black having minimum brightness, a black detecting signal 9 having minimum brightness is transmitted to a selector 2 from an ABK detecting block 3. When the selector receives the detecting signal, it transmits a substitution data 11 to black having minimum brightness previously sent from a CPU 5 to a printing block at a post-stage. When a data read from the memory represents white having maximum brightness, a white detecting signal 10 having maximum brightness is transmitted to the selector 2 from an AWH detecting block 4, and the selector similarly sends a substitution data 12 to white having maximum brightness previously transmitted from the CPU 5 to the printing block at the post-stage. Dots printed onto paper, etc. is printed in white in dots represented by black having minimum brightness on a host device, and dots represented by white having maximum brightness is printed in black.

A gasket closes the upper opening of the cylinder member 31 and the smoke candle is sealed in the cylinder member 31 having its upper end opening closed with the gasket. When operation is done, smoking chemicals in respective smoke candles 50 are electrically ignited and the seal 52 is broken, so that smoke spouts out of the lower ends of the smoke candles 50. No raindrop falls directly on the smoke candles 50. Consequently, secure smoking is always obtained irrelevantly to weather.

Title: Grinding wheel for on-line roll grinding
Inventor: HENMI YOSHINORI
IPC: B24D7/00
Filed: 1988-05-28
Abstract: PURPOSE:To prevent any damage such as chipping and cracking from occurring in an angular part of a peripheral edge of a grinding wheel tip face by forming at least either side of both inner and outer circumferential surfaces of the grinding wheel into a tapered surface being tilted to a cylindrical surface in parallel with a shaft center so as to cause radial wall thickness to become smaller in proportion as going toward the grinding wheel tip face. CONSTITUTION:In such a state that a tip end face 18 of a cylindrical grinding wheel is pressed to an outer circumferential surface of a roll, sliding friction is produced in an interval between this roll outer circumferential surface and the grinding wheel, and the roll outer circumferential surface is ground with on-line. At this time, an outer circumferential surface 16 of a stone body 12 is formed into a tapered surface being tilted at an angle alpha (25-40 deg.) to a cylindrical surface in parallel with a shaft center so as to cause radial wall thickness of the stone body 12 to become smaller in proportion as going toward the tip end face 18 being pressed to the roll. In addition, this tip end face 18 is formed into a tapered surface being tilted at an angle theta (0.5-1 deg.) from a plane at a right angle with the shaft center in proportion as going toward the outer circumferential side. In consequence, impact resistance in an angular part 28 of the peripheral edge of this tip end face 18 is well enhanced.
