Title: Gas turbine burner
Inventor: ISHIBASHI YOJI
IPC: F23R3/34
Filed: 1987-06-05
Abstract: PURPOSE:To provide low NOx in a gas turbine combustion unit realizing a high speed stability and a wide range of operation by a method wherein an outlet of an annular air passage is abruptly expanded. CONSTITUTION:Inner circumferential passage wall side of a flame holding plate 7 at an outlet port of an annular passage is made in a short tapered form and an auxiliary inner cylinder passage wall 8 of which diameter is reduced is attached to the inner peripheral passage wall downstream of the tapered part. With this arrangement, a part of flow of pre-mixture gas along an inner cylinder passage wall 5 is peeled off owing to an abrupt expansion of the passage and thus a recirculation flow is generated. In case of this recirculation flow, the staying time of the pre-mixture gas is extended, resulting in that a sufficient chemical reaction time can be attained and a combustion reaction can be promoted. Therefore, even if the surrounding shows a high speed flow, a flame can be kept and a stable flame can be attained, resulting in decreasing NOx.

Title: Air-fuel ratio control system for internal-combustion engine
Inventor: KISHIMOTO YUUJI
IPC: F02D41/18
Filed: 1981-09-03
Abstract: PURPOSE:To effect fuel amount control upon deceleration with a good response by a method wherein a suction air volume detecting means, excellent in the response thereof and outputting a frequency, is employed to enable to estimate the decrease of the suction air volume upon deceleration of the engine. CONSTITUTION:An output pulse, being outputted from a k am n's vortex type airflow meter 2 and having the frequency proportional to the suction air volume, is inputted into a counter 302 receiving the pulse input of a constant frequency outputted from a clock generating means 301 and the frequency thereof is measured. On the other hand, a register 303 latches the measured value of the frequency of the counter 302 at every input of the output pulse of the flow meter 2. A comparing means 304 outputs the largest value among these frequencies into a fuel amount operating unit 305. According to such operations, the period of the output pulse of the flow meter 2 becomes larger as compared with the prior measurement upon deceleration, therefore, coming of the pulse may be estimated when the value of the counter 302 has exceeded the period of the prior measurement, and the fuel amount may be reduced.

Title: Semiconductor laser array device
Inventor: ITO KUNIO
IPC: H01S5/00
Filed: 1986-06-17
Abstract: PURPOSE:To lower the optical density of laser beams on the end surfaces of a laser crystal while reducing the generation of heat on the end surfaces by making the film thickness of an active layer at both resonator end surface sections of the laser crystal thinner than the inside of the crystal and preventing the flowing of currents through the end surface sections. CONSTITUTION:A mesa 9 is formed onto a p-type GaAs substrate 1 through etching, the mesa 9 is buried completely through a liquid phase epitaxial growth method, an n-type GaAs layer 2 is grown so that the surface is flattened, and ridges 11 and three grooves 10 are shaped through etching. The grooves 10 are made to reach the mesa 9 at a section where there is the mesa 9, the width of the ridges 11 is narrowed at sections where there is no mesa, and second liquid phase epitaxial growth is conducted onto the substrate, thus growing multilayered structure. Since a growth rate on the ridges 11 is decreased with the narrowing of the width of the ridges 11 at that time, an active layer is thinned at end surface sections where the width of the ridges is made narrower than the inside of a crystal. When the active layer is thinned, the confinement of beams is deteriorated, and the beam diameter of laser beams is increased in the vicinity of the end surfaces, thus reducing optical density.

Title: Fixation base plate for spherical mosaic
Inventor: MORITO YUKO
IPC: B44C3/12
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To seal spherical mosaic pieces such as small glass-balls uniformly without rolling, and fix them surely firmly in the case of being arranged and fixed in accordance with a motive. SOLUTION: A sealing agent 4 for sealing a base plate main body 3 and spherical mosaic pieces 2 on the surface of the base plate main body 3 is applied in dotted relation in accordance with arrangement positions of the spherical mosaic pieces 2. The sealing agent 4 exhibits adhesiveness by an organic adhesive before heating because it consists of mainly an organic adhesive and low softening point glass, and when heated, the low softening point glass is softened in a manner causing the spherical mosaic pieces 2 and base plate main body 3 to be sealed. Also, since the sealing agent 4 is applied in dotted relation, unevenness never occurs in thickness as in overall surface application; moreover, the film thickness can be made thick compared with overall application, as a result, it leads to a reduced amount of use of the adhesive agent 4 even in this thick application. In addition, it has no glimpse of residual parts of the lower softening point glass through interstices thereof after sealing.

Abstract: PROBLEM TO BE SOLVED: To eliminate a phenomenon such as offset or strike-through while maintaining the uniformity of solid print by a simple and low cost process, in a method and a device for making up a heat-sensitive stencil base paper. SOLUTION: A thermal head 5 comprises one set 50 of heating elements 50a, 50b per one pixel, on a heat-sensitive stencil base paper to be made up by the thermal head 5, i.e., of a printed image and individual electrodes 53 commonly connected to the heating elements 50a, 50b for supplying power to each of the heating elements 50a, 50b equivalent to one pixel. Perforations equivalent to one pixel are opened by the one set 50 of the heating elements 50a, 50b and the heat-sensitive stencil base paper thus made up is used to perform the printing. Thus it is possible to perforate the stencil paper for printing an image with high resolution and thereby eliminate an offset phenomenon. The resolution of the individual electrodes 53 suffices to ensure the resolution of a scanner or the like. Consequently, the offset or strike-through phenomenon can be eliminated at a low cost.

Filed: 1977-11-24
Abstract: PURPOSE: To prevent the formation of local high temperature part in a flame center to control generation of NO x  by giving strong gyrating force to combustion air eddy so that its mixture with fuel injection be promoted, and by thus forming a short- lived fast burning flame.  
     CONSTITUTION: Air guide vane 18 is constructed at a combustion air supply passage to generate air having strong gyrating movement. A narrow straight raw tile 17 of a straight cylinder type with a combustion nozzle 14 inserted inside at good length is set to produce high speed air flow. The narrow formation of a  straight cylinder type in a burner tile 17 produces no main reaction area of combustion inside the tile 17, thereby preventing the overheat of inside walls and keeping the flame temperature low. Furthermore, the generation of fast burning flame makes possible low air ratio combustion and the recycle flow in flame center increases the stability of flame.
