Patent JP-H04111379-A (JP)
Title: Visible-ray semiconductor laser
Inventor: SHONO MASAYUKI
IPC: H01S5/323
Filed: 1990-08-30
Abstract: PURPOSE:To enhance the doping efficiency of an n-type dopant and to raise a maximum oscillation temperature by a method wherein the inclination direction of a substrate provided with a crystal growth plane tilted from a (100) plane is set to a direction which is dislocated by a specific angle from the <011> direction to the <011> direction. CONSTITUTION:A GaAs substrate is manufactured in such a way that the crystal growth plane of the substrate is set to a plane tilted by 7 deg. from a (100) plane and that its inclination direction is changed variously within a range from the <011> direction to the <011> direction. A GaInP layer is grown on the crystal growth plane of the substrate. A change in the band gap of this growth layer is measured. The larger an angle alpha is, the smaller a band gap becomes. However, it is found that its change amount is small within a range of 0<alpha<=30 deg. and that the band gap is hardly changed when alpha=0, i.e., the inclination direction is set to the <011> direction. Such a characteristic is obtained in the same manner when the inclination direction of the substrate is dislocated to a crystallographically equivalent direction, i.e., from the <011> direction to the <011> direction.

Title: Controller of industrial robot
Inventor: TAJIMA HITOSHI
IPC: B25J9/22
Filed: 1984-10-31
Abstract: PURPOSE:To omit a manual complementary job by actuating a detection means when an industrial robot has a working error and executing again the corresponding working instruction. CONSTITUTION:A reading means 32 reads a series of working instructions out of a memory means 31, and an industrial robot 8 is driven and controlled by these instructions. A detection means 30 works in case the robot 8 does not perform accurately a job. Then a writing means 33 writes the working instructions to the means 31 according to the working results of the robot 8. If a working error is produced, the store address of the final data is increased to copy the data set under execution to said increased address. At the same time, the remaining execution frequency is increased by one. Thus the work having an error is executed finally and therefore a working instruction corresponding to the error can be executed again with no intervention of a manual operation.

Title: Reproducing device of digital signal
Inventor: MORIYAMA MASARU
IPC: G11B5/09
Filed: 1982-12-24
Abstract: PURPOSE:To attain stable and accurate reproduction of a digital signal by absorbing variation in a reproducing signal at each track to ensure the interchangeability of tracks and setting a threshold value at an amplitude region where AC reproduced digital signal component is zero. CONSTITUTION:A fixed magnetic head has plural gaps for the reduction of transmission bit rate, a digital signal is recorded decentralizedly on plural tracks in parallel with the running direction of a medium, and in applying the head for a multi-track recording and reproduction, the interchangeability among different recording and reproducing devices is attained by absorbing the variation in reproducing signals. Further, since a timing component is extracted after a peak value or an average value of the reproducing signal is controlled to a constant value, the level adjustment of the reproducing signal is not required to attain stable comparison. Since the threshold value of the digital signal at the zero crossing region is set and the digital signal is discriminated positively as digital data of logical zero, the digital signal is reproduced stably and accurately.

Title: Method and apparatus for treating nitrogen oxide
Inventor: NAKAHIRA TAKATOSHI
IPC: B01D53/94
Filed: 1992-08-31
Abstract: PURPOSE:To remove and purify an exhaust gas with a simple and small constitution by using a compd. wherein gallium is a main ingredient as a catalyst and a hydrocarbon as a reduction gas and performing reduction reaction of nitrogen oxide at a specified temp. CONSTITUTION:Reduction reaction of nitrogen oxide is performed at 400-900 deg.C by using a compd. wherein gallium oxide (Ga2O3) is a main ingredient as a catalyst and a hydrocarbon as a reduction gas. In this case, nitrogen oxide is changed into nitrogen, carbon dioxide and water by reacting with the hydrocarbon based on a catalytic action. This reaction proceeds even when such a hydrocarbon with small number of carbon as methane is used as the reduction gas. As methane being an ingredient of city gas can be used when methane is used as the reduction gas, in a combustor using this as a fuel, it is possible to obtain an NOx-free clean gas by e.g. feeding methane in the exhaust gas in the combustor by making a combustor as a by-pass from the same city gas feeding source and introducing a gas in a mixed condition to a catalytic part.

Abstract: PURPOSE: To measure the quantity of a fluid in a container, presence of a contaminant, and temperature of the fluid with high accuracy by providing a fluid quantity measuring sensor, a sensor for measuring a capacitance which varies depending upon the characteristics of the fluid, and a fluid temperature measuring sensor. CONSTITUTION: A reference and fluid quantity sensor 31 measures both the dielectric constant and quantity of a fuel in a tank and incorporates a reference cell 311 and product measuring cell 312. Both cells 311 and 312 are effectively arranged so that the cells can form a cylindrical capacitor together with the fuel which works as a dielectric substance and the capacitance related to both cells is determined and used to indicate the quantity of the fuel in the tank. An existing contaminant detecting sensor 32 judges the existence of a contaminant, especially, water by detecting the change of the dielectric constant of the interposed fluid by measuring the capacitance. A temperature sensor 33 is connected to a circuit board 41 through a wired conductor group 34. The temperature data fetched from the sensor 33 are transmitted to a circuit on the circuit board 41.  The board 41 not only interfaces the data from the sensors 31 and 32 with a common controller, but also the data from the sensor 33.
