Title: Combustion device and combustion method
Inventor: ITO MEIJI
IPC: F23C99/00
Filed: 1993-03-17
Abstract: PURPOSE:To improve a noncatalytic denitrification performance by a method wherein even if discharged gas of unstable gas composition is produced by combustion, a concentration of nitrogen oxide is prevented from being increased through adding of reducing agent for denitrification. CONSTITUTION:Water is supplied to a gasification device 7 through a water supplying line 24 and ammonia water is supplied to the gasification device 7 through an ammonia water supplying line 25, respectively. The ammonia water and the water are heated by the gasification device 7 to produce mixture vapor in which gasified ammonia is mixed with water vapor and then the mixed vapor is supplied to a combustion gas region through an ammonia adding line 27 where combustion gas within a combustion furnace 1 and ammonia are reacted to each other. In reference to a sensing temperature signal got by a temperature sensor 12 and a detected NOx density signal by a NOx densitometer 13, a control device 8 outputs a water flow rate control signal to a control valve 11 when the detected temperature and the detected NOx density are higher than each of their reference values, and sends the water from the water supplying line 26 to the gasification device 7 so as to increase an amount of water vapor contained in the mixture vapor.

Title: High humidity and low temperature case
Inventor: HARUNA HIDETADA
IPC: F25D23/00
Filed: 1989-03-08
Abstract: PURPOSE:To provide a large amount of returned humidity, enable a storing chamber to be kept at a high humidity and enable both effects of cooling and humidifying to be attained by a method wherein an air stream from an air blower fan is passed through an evaporator and along both front and rear surfaces of a moisture evaporating plate and the dew dripped from the evaporator down to the moisture evaporating plate is forcedly evaporated by the air stream. CONSTITUTION:During a defrosting operation, dew is dripped from an evaporator onto moisture evaporating plates 21 and 22. As an amount of dew at the moisture evaporating plate becomes a predetermined amount, a substantial entire area of the surface becomes wet. In addition, dew dripped from the hole 23 downwardly is dispersed to the rear surface of the moisture evaporating plate by a forced circulating air stream from an air blower fan 30, the rear surface as well as the front surface is wet and the dews at both front and rear surfaces of the moisture evaporating plate are forcedly evaporated by the forced circulating air stream. The moisture evaporating plate is arranged with a proper spacing being left against the evaporator 20, resulting in that even if a refrigerant evaporating temperature is a minus temperature less than 0 deg.C by several degrees, the dew at the moisture evaporating plate is not freezed and the dew left even if the cooling operation is continued is evaporated with the forced circulating air stream and then the dew is returned back to a storing chamber. With such an arrangement, effects of cooling and humidifying can be attained.

Title: Curved shape forming machine for metallic long sized roofing sheet
Inventor: ITOU YOSHIO
IPC: B21D13/04
Filed: 1980-04-28
Abstract: PURPOSE: To continuously manufacture a curved part of a roofing sheet provided with several  trapezoidal uneven grooves in the longitudinal direction for the purpose of simply improving the  mechanical strength, by forming a roofing sheet into a prescribed curvature, while forming a  wavy draw bead in the bottom and both sides of the roofing sheet by automatically feeding into  upper and lower forming rollers.  
     CONSTITUTION: A metallic long sized roofing sheet, being fed in the arrowed direction from the  right side, is bitten by upper and lower rollers (a), (b) and is formed into a prescribed curvature  of an edge of eves or an edge of the roof, and is carried away in the arrowed direction to the left  side. Since this curve forming work is applied to a part of the roofing sheet, a piston rod 3 is withdrawn upward after detecting the curved length, and a awing arm 4 is turned around the shaft 5  in order to release the drawing work. After the formed roofing sheet is completely carried away,  the piston rod 3 is again brought down, and the arm 4 is turned around until a stopper bolt 6 is  stopped by a step metal 7, and the upper roller (a) is set at a prescribed setting condition. The  bolt 6 is engaged with a setting seat 9 welded to a cover plate 8 provided with the left and right  arms 4 in one body; by adjusting this bolt 6, the biting depth of the rollers (a), (b) is changed,  and the curvature of the worked part is adjusted.

Title: Multimode saw filter
Inventor: TANAKA MASAKI
IPC: H03H9/25
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To attenuate the spurious at a point near the center frequency and to decrease the number of cascaded stages for reduction of the cost and size of a multimode SAW filter by shifting the position of at least one of laterally coupled multimode filters in the transmitting direction of a surface wave. SOLUTION: The positions of IDT 2 and 4 are shifted from the positions of IDT 6 and 8 of a laterally coupled multimode filter in the transmitting direction of a surface wave with a space D set as D=(λ/8+nλ/4) between them (n = 1, 2, 3...). When the IDT of a filter A is shifted from the IDT of a filter B by λ/8 in the transmitting direction of the surface wave, the phase difference is equal to λ/4 between the surface waves which are leaked out of both filters A and B and reflected at both ends of a substrate. Thereby, no standing wave is generated by a spurious component to the filter B to suppress the spurious since the filter B has a phase difference between the reflected and traveling waves that is shifted from the phase difference of the filter A by λ/4 when the filter A has the spurious.

Title: Decoder and device in common use for coding and decoding
Inventor: HAMAMICHI AKIHIRO
IPC: H04N1/419
Filed: 1993-03-18
Abstract: PURPOSE:To test the decoding processing in a state close to the real operation by using a counter to be sharing at the time of decoding and at the time of test and performing an output of a comparator synchronously with a run length detection timing in the case of a rest request. CONSTITUTION:A color fed from a decoding section 2 is latched in a latch 3a, a run length is latched in a counter 4 and a shift register 5 receiving an output of the latch 3a is shifted by a value set to the counter 4. Thus, the content of the register 5 is outputted to an output section 6 for each shift. Upon a test request, the counter 4 is cleared to input coded picture information to an input section 1. Then the counter 4 does not latch the run length and counts up an output of the run length from the decoding section 2 once per twice and the value is coincident with an output run length from the decoding section 2. Thus, an error in a table and decoding processing is tested by providing an output of the comparator 7 for each run length output of the decoding section 2.

Abstract: PURPOSE:To average the time of completion of a reference clock write and to shorten the average time of write completion, by detecting a rotation period of the highest frequency of generation to select a reference clock frequency. CONSTITUTION:A read/write part 2 writes a rotation period measuring pulse signal on the circle of a disc medium 1 and reads out this pulse signal to output it to a sampling circuit 3.

The read/write part 2 outputs the clock signal, which is read out from the disc medium 1, to a verifying part 6, and the part 6 discriminates whether the clock signal satisfies the frequency constancy and the phase matching condition or not and outputs the discrimination result to the processor part 4. The processor part 4 controls the clock part 5 to write the clock signal repeatedly; and the write is terminated when the clock signal satisfies the frequency constancy and the phase matching condition.
