Title: Design method of semiconductor optical integrated element
Inventor: YAMAZAKI HIROYUKI
IPC: H01S5/026
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To improve oscillation characteristic of an active layer, design a semiconductor optical integrated element which reduces combination loss of a tapered waveguide layer and enable accurate manufacture by designing a growth element film pattern used for a selective MOVPE growth method by using a specified one dimensional extended equation. SOLUTION: A semiconductor optical integrated element is prepared by a selected MOVPE method for forming a desired layer in an optical part by using a pair of opposed growth blocking films 10 in a y-direction with a strip- like opening which extends in an x-direction on the x-y coordinate plane. Growth rates Rx (x) and Ry (y) in x-direction and y-direction of a growth layer in an opening part can be obtained by using equation 1 and equation 2 wherein R∞ is the growth rate at a point sufficiently far from the growth blocking film 10, Ro is the local growth rate, Lxdiff and Lydiff are diffusion length in the x- direction and the y-direction, respectively and τ (x, y) is the raw material life. Therefore, control of fine tapered waveguide shape is possible and an SSC-LD with good oscillation characteristic can be obtained.

Filed: 1987-07-29
Abstract: PURPOSE:To facilitate the conversion between the documents of different formats by providing a table where the continuance relation is described among rectangular areas which controls the inside of the document and changing the format with no change given to the number of characters in one page by reference to said table when the format is changed. CONSTITUTION:The inside of a document is controlled for each rectangular area and the character areas A-C and a graphic area X are provided. A table is provided to control an area ID, a position, a size, an attribute, continuous area ID for character areas, etc., for each rectangular area. The column composition is changed by referring to the table for each area. Then the number of characters equal to that set before change is copied to anew rectangular area. Thus the column composition can be changed without changing the number of characters within one page.

Title: Multicolor rotary press
Inventor: HAYASHI NORIKI
IPC: B41F23/02
Filed: 1990-07-16
Abstract: PURPOSE:To prevent a fan out from occurring so as to stabilize the quality of an image in multicolor printing by providing spray members for spraying water on both faces of a traveling paper before entering a printing unit at the lowest step. CONSTITUTION:Spray members 1 are provided on both face sides of a traveling paper P in such a manner that water can be sprayed on the both faces of the traveling paper P before entering a printing unit 11 at the lowest step. The traveling paper P receives water spray on its both faces from a nozzle 3 of the spray members 1 before the paper enters the printing unit 11 at the lowest step and extends in the cross direction due to the attachment of the water. The extended paper enters the printing unit 11 at the lowest step. At this time, since the traveling paper P is already extended fully in the cross direction, the paper will not extend much even if the paper receives damping water at the unit 11 and retains at 0.2mm which is an allowable range of a fan out in the multicolor printing. Accordingly, large fan out will not occur.

Filed: 1990-07-18
Abstract: PURPOSE:To make the device small and to reduce the cost by selecting a reference period corresponding to each signal to be measured to detect the propriety of plural kids of signals to be measured at a single detection device section. CONSTITUTION:A reset signal supply section 1010 outputs a signal synchronously with a pulse 1001 in the FG pulse detection mode and a signal synchronously with a laser beam detection signal 665 in the detection mode of the laser beam detection signal 665 to a time measurement section 1006. The measurement section 1006 measures an interval time of the signal 1011 in each detection mode and measures a period of a periodic laser beam detection signal of the FG pulse respectively. A time setting section 1005 selects a reference time in response to a control command from a CPU. Then a comparison section 1007 compares a period of a signal to be measured with the reference period and sends an error detection signal 1004 when the signal to be measured represents a defect. Thus, the propriety of the plural signals to be measured is detected by a single detection device section and the device is made small and the cost is reduced.

Patent JP-S6170246-A (JP)
Title: V-belt
Inventor: HIRANO HIROYUKI
IPC: F16G5/16
Filed: 1984-09-11
Abstract: PURPOSE:To prevent the breakage of metal bands by decreasing the width- direction size of the metal bands constituting a layer-like band toward the outer-periphery side and preventing the contact between the metal bands and the pulley face. CONSTITUTION:A metal band 10e on the outer periphery side has a possibility to be displaced relatively largely in the width direction when a distortional force is applied to a V-belt, and the size of a metal band 10e in the width direction is made smallest. Accordingly, the metal band toward the outer- periphery side has a larger gap from the pulley face than the one on the inner- periphery side, thus metal bands 10a-10e constituting a metal band 10 are never brought into contact with the pulley face while the rotating force is transmitted. Therefore, a trouble that the metal bands 10a-10e are broken never occurs.
