Title: Optical integrated circuit
Inventor: HORI YOSHIKAZU
IPC: G02B6/122
Filed: 1986-12-26
Abstract: PURPOSE:To obtain an optical integrated circuit having good reproducibility and high performance by integrating an optical element containing a grating coupler formed on a two-dimensional waveguide, onto a substrate, and leading a laser light beam into the two-dimensional optical waveguide through a three-dimensional optical waveguide. CONSTITUTION:An SiO2 loading layer 5 is provided on an optical coupling part to a semiconductor laser 4, and in this area, the loading layer 5 becomes a clad, and as for the loading layer 5, its refractive index is higher than that of air of the peripheral part, therefore, the confinement of light in the horizontal direction is executed, and a three-dimensional waveguide of a single mode is formed. Accordingly, a light beam emitted from the semiconductor laser is propagated through this three- dimensional waveguide, and the light beam which has reached a terminal is propagated to a two-dimensional waveguide, while diverging as a columnar wave. In such a way, since the three-dimensional waveguide is formed as one body with a substrate 1, a distance between a grating coupler 6 and the three-dimensional waveguide can be formed exactly and with high accuracy, an emitted light from the semiconductor laser has good reproducibility and a condensing spot being near a diffraction limit can be obtained.

Title: Method for removing dust in sintered ore cooler
Inventor: KOYANAGI YASUAKI
IPC: F27D17/00
Filed: 1993-12-13
Abstract: PURPOSE:To perform an efficient dust-removing at a less-expensive facility expenditure by a method wherein two-layer fluid of water and air is atomized to discharging gas containing dusts passed through a sintered ore layer within a sintered ore cooler pan and ascending through it, fine powder ores contained in the discharged gas are settled and adhered within a sintered ore product and discharged from the ore discharging part of the cooler pan together with the sintered ore product. CONSTITUTION:A plurality of atomizing nozzles 14 are arranged above a fixed hood 7 installed at an upper part of a cooler pan 6 along an advancing direction of the sintered ore and they are installed in such a manner that the number of nozzles is increased as they approach a discharging cylinder 10. As atomized water droplets atomized from the atomization nozzles 14, two-layer fluid of water and air is applied, the atomizing positions may well be adapted in an area showing a slow gas flow rate in such a way that the settling of the fine powder ores is promoted and their proper positions are spaced apart by about 500 to 1000mm from the surface of the sintered ore layer 15 within the cools pan 6. The fine powder ores in the contained gas 13 strike against the atomized water droplets and the ores are struck down, resulting in that the ores are settled and adhered into the sintered ore product and then discharged out of the ore discharging part 8 of the cooler pan 6 together with the sintered ore product. With such an arrangement as above, it is possible to remove dusts with a less- expensive facility cost.

Title: Control method and device of serial printer
Inventor: NAKAYAMA ICHIRO
IPC: B41J19/18
Filed: 1992-11-20
Abstract: PURPOSE:To reduce a specified enumerated value and speed up printing by a method wherein character selection of first digit to be printed serially in a previous line is performed by counting a specified enumerated value of timing pulses which start to generate during carriage return. CONSTITUTION:When printing for one line is completed by repeating a loop at a step P1a, the number of return wait timing pulses corresponding to the number of digits printed at a step P1b is set. As for setting method, there are two methods: a method to select from two kinds of waiting times with boundary at certain number of digits of printing, and a method to employ a different value every time the number of digits of printing changes by one digit. At a loop of a step P1c, timing pulses are counted. After a waiting for the number of return wait timing pulses set at the step P1b, printing for one line is completed. Further, it is confirmed whether printing of next line exists or not at a step P1d. When it exists, the routine returns to the step P1a and the above operation is repeated. If it does not exist, the whole printing operation is completed.

Title: Timer monitor system
Inventor: SATO NOBUYOSHI
IPC: G06F11/30
Filed: 1990-11-19
Abstract: PURPOSE:To surely monitor timer operation by detecting the time interval between a timer interruption and a successively initiated interruption by an interruption interval monitor means, and judging timer abnormality and generating an alarm when the interval is larger than a specific value. CONSTITUTION:A timer 1 is set to, for example, 60 seconds and a threshold value 11 is set to 60 equal to the value of the timer. The interruption interval monitor part 10 has two areas A and B internally. When an interruption is initiated, it is decided whether the interruption is caused owing to hardware trouble or mechanically and then it is decided whether the interruption is the timer interruption; when so, the monitor part 10 records the time of the interruption in the area A. If an I/O interruption is caused by an input/output device, the monitor part 10 reads TOD15 in the area B, compares the difference (B-A) with the value 60 of the threshold value 11, and judges that the interruption is abnormal when (B-A) is larger to set the timer interruption in an interruption register 4 at the same time with the code of timer abnormality, thereby initiating the interruption.
