Title: Method for measuring quarity of annular communication line
Inventor: KIKUCHI KENJI
IPC: H04L1/00
Filed: 1982-09-29
Abstract: PURPOSE:To calculate a bit error ratio highly accurately by using a synchronous protection circuit to measure the error of a frame bit. CONSTITUTION:When a state is transferred from S5 to S6, a comparator 13 discriminates A>B because synchronous information S6 is larger than S5, so that the input terminal IN of a counter 14 is activated and the counter 14 counts up ''1''. If the frame bit becomes an error under said condition, the state is moved to S7 and the counter 14 adds ''1'' to count up ''2'' in the same manner. If the frame bit becomes an error under said status thereafter, the state is moved to S8 and the counter 14 counts up ''3''. When the frame bit becomes an error moreover, the state is returned to S0. Thus, the frame bit errors after setting up the synchronous status can be counted, so that the error ratio on the transmission line can be calculated from the counted value within a fixed period.

Title: Treatment of exhaust gas by addition of ozone/ammonia
Inventor: NANBA HIDEKI
IPC: B01D53/34
Filed: 1984-08-16
Abstract: PURPOSE:To simultaneously remove NOx and SOx by a dry process, in a method for treating exhaust gas, by adding O3 and NH3 to exhaust gas containing NOx and SOx to convert NOx and SOx to solid products. CONSTITUTION:Exhaust gas containing NOx and SOx is introduced into an O3-reaction tank while O3 is added to said exhaust gas and NOx is oxidized to HNO3 or HNO2 by O3 and water. The amount to be added of O3 is determined and regulated by the optimum condition of the whole of a process. In the next stage, NH3 is added to respectively convert HNO3 and HNO2 to NH4NO3 and NH4NO2 and SOx receives oxidation reaction to form (NH4)2SO4. NH4NO2 in the front stage of an NH3-reaction tank is further oxidized to NH4NO3 and the formed salt is collected bya collector while treated gas is exhausted from a chimney through a blower.

Title: Geometric correction processing device
Inventor: SHIMIZU SHINICHI
IPC: G06K9/36
Filed: 1979-12-29
Abstract: PURPOSE:To convert the inclined figure pattern to a no-inclined figure pattern by a simple circuit, by performing a specific coordinate axis rotation processing. CONSTITUTION:The reciprocals of inclination of the inclined figure pattern to coordinate axes (x) and (y) are calculated by the circuit consisting of subtracting  circuits 6 and 7, reciprocal circuit 8, and multiplying circuit 9, and its integer N is  obtained. Next, the figure pattern is moved in the (x) axis direction by N addresses and is moved in the (y) axis direction by one address according to integer N by N-notation set counter 17 and counters 15 and 16. The circuit consisting of N-notation set counter 17 and counters 15 and 16 moves the figure pattern in the (x) axis direction by one address when the figure pattern advances in the (y) axis direction by N addresses. Thus, data corrected in respect to (x) and (y) axes are read successively along coordinate axes X and Y and are written into the storage part having addresses corresponding to coordinate axes (x) and (y). As a result, the inclined pattern is converted to a no-inclined pattern simply.

Title: Detector for boundary of optical image
Inventor: IGARASHI MATSUHISA
IPC: G01B11/00
Filed: 1983-09-16
Abstract: PURPOSE:To obtain a detector which has a simple and small-sized structure and has no detection directional characteristics and measures boundary positions between brightness and darkness with one scanning, by obtaining an S-shaped curve as subtraction signals between amplified signal of four photoelectric transducers arranged in positions corresponding to vertexes, and the amplified signal of a photoelectric transducer arranged in a position corresponding to the center and defining zero-crossing points as boundary detection positions. CONSTITUTION:When all of photoelectric transducers 1c-1e enter in a bright area in a position P5, levels of respective output signals are fixed. When a boundary (l) between brightness and darkness is put on a photoelectric transducer 1b in a position P6, the level of an output signal b2 of an amplifier 2b starts increasing as shown in a figure (b). When the photoelectric transducer 1b enters in the bright area completely in a position P7, the level of the output signal b2 is fixed. Consequently, the output signal of an adding circuit 3 is changed as shown in a figure (f). Therefore, the output signal of a subtracting circuit 4 is the S-shaped curve where the zero-crossing point is a center position P4 of the photoelectric transducer 1e as shown in a figure (g). Since the indication is different before and after the center position P4 on an analog indicating meter 5 driven by this S-shaped curve, the center position P4 is easy to read.

Title: Production of spherical pullulan particle
Inventor: MOTOZATO YOSHIAKI
IPC: B01D39/04
Filed: 1985-08-02
Abstract: PURPOSE:To obtain spherical pullulan particles which are excellent in pressure resistance and whose exclusion limit MW can be varied widely, by suspending an ester of pullulan in an aqueous medium to form a suspension of spherical particles of pullulan, saponifying these particles and reacting them with a crosslinking agent in an organic medium. CONSTITUTION:An ester of pullulan is dissolved in a solvent which has a b.p. lower than that of an aqueous medium and does not dissolve in an aqueous medium at all or dissolves only slightly. This solution is suspended in an aqueous medium to form a suspension of liquid drops and, at the same time or after this, the solvent is evaporated from the liquid drops to obtain spherical particles of the pullulan ester. These spherical particles are saponified and then reacted with a crosslinking agent in an organic medium. Acetic acid is the most suitable as the acid used for the esterification because of easiness in handling. Desirable solvents include chlorinated hydrocarbons such as dichloromethane and 1,1,1-trichloroethane.

A disk is punched out of the resulting sheet to provide a PTC element. Since the plasma-processed conductive sheet is used, the conductive sheet is uniformly roughened and satisfactory adhesiveness is exhibited between the electrode and the conductive sheet.

Abstract: PURPOSE:To access a tape only by a reel motor by obtaining the timing of the acceleration stop and speed reduction through the arithmetic of the prescribed speed value and current and goal addresses. CONSTITUTION:A magnetic tape 1 is traveled along a tape guide drum 2. A reel motor 56 is controlled so that a speed up and down of the magnetic tape 1 is made possible at the prescribed speed-up control by a periodical speed modification. When a goal address where a tape position is accessed is given by a key device 25, a system control circuit 5 obtains the timing of a speed-up stop and speed-down start by the arithmetic of the prescribed speed-up value and goal and current addresses, and a system control circuit is controlled according to said timing. Namely, the reel motor 56 is controlled up to the timing of the speed-up stop, whereby the magnetic tape 1 is sped up at the prescribed acceleration. On the other hand, after the timing of the speed-down start passes, the reel motor 56 is controlled, and the magnetic tape 1 is sped down at the prescribed speed, whereby the tape position is accessed at the goal address.
