Title: Waste water treatment method for removal of nitrogen and device therefor
Inventor: HASEGAWA JUN
IPC: C02F3/08
Filed: 1993-12-28
Abstract: PURPOSE:To efficiently remove BOD components and nitrogen-component in waste water by partitioning the inside of the same vessel to an aerobic region and anaerobic region, packing dispersion type carriers as catalysts to immobilize microorganisms into this aerobic region, executing aeration and passing the waste water through both regions. CONSTITUTION:The underwater floatable dispersion type porous carriers are packed into the treating vessel 1 and are immersed into the waste water so as to be constituted as a contact maternal layer 2. The inside of this treating vessel l is partitioned by partition plates 3 to a BOD treating region, nitrifying region, denitrifying region and reaerating region. A diffusion pipe 4 for aeration is installed in the bottom of the vessel to effect aeration in the regions exclusive of the denitrifying region. The denitrifying region is provided with a cap 5 and is maintained in an anaerobic atm. The waste water first flows into the BOD treating region in the treating vessel l and flows down in the nitrifying region, the denitrifying region and the reaerating region in the treating vessel in this order and is subjected to biological treatments in the respective regions. The waste water is thereafter circulated partly to the BOD treating region and the other part is discharged from a waste water outflow port so as to be admitted into a settling chamber 6.

Title: Two-dimensional code reader and storage medium
Inventor: YOU KIYOKUKA
IPC: G06K7/10
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To properly set a range wherein the kind of a cell is read even if distortion is present in a detected two-dimensional image by adjusting the extent of a range for reading the contents of the cell according to the distance to a standard pattern and reading the contents of the cell out of the range adjusted by groups at each cell position. SOLUTION: An image memory 8 and an address storage memory 22 are accessed to determine an accurate center position on an image of a positioning symbol according to their storage contents. According to cell shapes found from the image of the positioning symbol, the shape of pixels read out of the image is determined. Consequently, even if the shape of a two-dimensional code 52 detected by a CCD 4 is distorted and then the shape of a cell image is different with the position, the image is read out within a proper range corresponding to the difference of the shape and the kind of the cell is determined by majority decision making. Therefore, the contents of the code that the positioning symbol represents can accurately be read.

Title: Semiconductor laser and its manufacture
Inventor: HINO ISAO
IPC: H01S5/00
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a semiconductor laser having a low oscillation threshold and excellent characteristics by a method wherein a double-hetero structure is provided and the energy gap of an active layer is changed along a layer thickness direction without changing the composition of the active layer. CONSTITUTION:An n-type (Al0.4Ga0.6)0.5In0.5P cladding layer 2 and an undoped Ga0.5In0.5 active layer 3 are built up on an n-type GaAs substrate 1. Successively, a p-type (Al0.4Ga0.6)0.5In0.5P cladding layer 4 and an n-type GaAs current blocking layer 5 are built up and the surface is selectively masked to remove the part of the n-type GaAs current blocking layer 5 corresponding to a current injection stripe part 7. Finally, a p-type GaAs cap layer 6 is built up and a p-type side electrode 8 and an n-type side electrode 9 are formed. Then the laminated unit is cleft into individual semiconductor lasers. Thus, by applying a non- reflective coating to the end surface of an element, creating an oscillation by an external resonator and providing a wavelength dispersing element in the resonator to make a wavelength variable, the variable wavelength range can be widened. With this constitution, a semiconductor laser having a wide variable wavelength range and a low threshold can be obtained.

Title: Combustion controller
Inventor: KOJIMA MASAKUNI
IPC: F23N3/08
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a combustion controller in which the time being elapsed before ignition can be shortened by shortening the time required for reaching a specified rotational speed. SOLUTION: Every time when the rotational speed of a fan reaches a target rotational speed, the voltage level being applied to a motor is stored, as an actual voltage level in an RAM. At the time of controlling the rotational speed of the fan again to that target rotational speed, a control voltage level is set by subtracting a specified value from the actual voltage level stored in the RAM when the fan is accelerated whereas a specified value is added to the actual voltage level when the fan is decelerated. The voltage level being applied to the motor is altered to the control voltage level and then subjected to feedback control thus shortening the time required for the fan to reach the target rotational speed, thereby shortening the time being elapsed before ignition.

IPC: G10H1/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide an automatic accompaniment device in which no sense of hearing incompatibility and musical unnaturalness are generated even though a reproducing tempo is increased while conducting an automatic accompaniment. SOLUTION: As a reproducing tempo TEMP is increased, a sound generating time is reduced and corrected for the musical sound having tone color in which sense of hearing incompatibility and musical unnaturalness do not appear even though the sound generating time is reduced and the shortage in the number of simultaneous sound generating tracks is eliminated. On the other hand, no reduction and correction are made in the sound generating time for the musical sound having a tone color in which sense of hearing incompatibility and musical unnaturalness appear as the sound generating time is reduced. Thus, even though the reproducing tempo is increased, no sense of hearing incompatibility and musical unnaturalness are generated while conducting an automatic accompaniment.
