Title: Light-emitting diode and its manufacture
Inventor: OGAWA HARUKI
IPC: H01L33/14
Filed: 1992-05-28
Abstract: PURPOSE:To obtain a light-emitting diode which has high luminance and excellent reliability by reducing the resistance of a window layer and suppressing the diffusion of a p-type impurity into an active layer in which crystals are being grown. CONSTITUTION:The hole concentration in a window layer 6a is set at p=1X10<18>cm<-3> in an 1-mum part near an active layer and at p=3X1018cm<-3> in the remaining 6-mum part. In other words, by lowering the Zn concentration in the part of the window layer 6a near the active layer, the diffusion of Zn into the active layer is suppressed and the generation of non-radiative recombination centers in the active layer can be prevented. When the Zn concentration in the part of the layer 6a far from the active layer is increased, the resistance in the layer 6a can be lowered.

Title: Cheese dyed cellulose filament
Inventor: NAKAGAWA MASANORI
IPC: D06B5/12
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain cheese dyed cellulose filament which is sufficient in dry tenacity and dry elongation to withstand practical use, free of color dullness otherwise encountered in the cheese dyeing and the like, excellent in uniform dyeing, and useful in knitting and embroidering as the color difference in dyeing is maintained within a prescribed range. SOLUTION: The color difference of this cellulose filament is <=1 NBS. To determine the color difference, the cheese dyed yarn is coat-divided into the innermost layer, middle layer and outermost layer, and each layer is respectively knitted by a knitting machine with one feeder. Using the cheese middle layer as the standard, the color difference is judged and calculated in accordance with the Adams-Nickerson's formula of color difference. The positive figure is regarded as the deep color dyeing and the negative figure pale color dyeing. The value 1 NBS means that the color difference between the innermost and the outermost layers is <=1. If the difference is >=1, color shading becomes conspicuous in such products as those weft knitted, and it unfavorably decreases the quality level of the product.

Abstract: PURPOSE:To execute a trouble forecasting model program which is provided beforehand and make it possible to judge whether or not a trouble has occurred by providing an electric current sensor which is installed in the electric power source circuit of an air conditioner, terminal unit for high-speed sampling, and central processing unit. CONSTITUTION:When an air conditioner 1 gets into stationary operation, a terminal unit 3 samples at a high speed the electric current values from an electric current sensor 2 and sends the electric current values to a central processing unit 4 at a fixed period. In this case, as for an air conditioner, etc., the value of the electric current passing through the electric power source circuit exhibits an abnormal change. By this change the electric current values which were sampled at a high speed contain information sufficient to reveal whether or not an abnormality exists in the air conditioner. In the central processing unit 4 a forecast model for diagnosing troubles is executed on the signals sent from the terminal unit 3, and when it is judged faulty, the maintenance personnel is informed of the content of the trouble and measures to be taken through an output device 5.

Title: Differential pressure transmitting device
Inventor: MURAI MASAHITO
IPC: G01L13/00
Filed: 1981-09-01
Abstract: PURPOSE:To prevent the effect of an air flow which causes measurement errors, by attaching an air flow shielding filter at the opening part of a pressure introducing pipe which is opened to atmosphere. CONSTITUTION:The air flow shielding filter 5 is formed in a spherical shape by sintered porous metal. The pressure introducing pipe 4 is attached to said filter 5 so that the pipe is opened at the central part of the filter 5. The air flow shielding filter 5 comprising the sintered porous metal is attached to the pressure introducing pipe 4 with the opening part 4a as the center. Therefore, even though the air flow blows suddenly, said flow is weakened before it reaches the opening part 4a of the pressure introducing pipe 4 and does not affect a reference pressure in the main body 1 of the differential pressure transmitting device.

Abstract: PURPOSE:To prevent molten metal from drooping from a groove by allowing magnetic force having specified directivity to act on welding current at the time of horizontal position welding and allowing upward force to act on molten metal in the molten pool by electromagnetic induction between the two. CONSTITUTION:Welding current is led flow between a base metal 1 having a groove in horizontal position and energizing tip 11 to generate an arc 18 between the tip of a welding wire 12 and the base metal 1, and a molten pool is formed by melting of the welding wire 12.

Abstract: PURPOSE:To improve the quality of material to be formed and to reduce the cost of a product by forming a coating layer of diamond having a specified range of thickness on the forming surface of a tool and performing cold working. CONSTITUTION:In working a hollow pipe 1 of Al, etc., with a punch 3 and a die 2 for the ironing purpose, a coating layer 2a of diamond with a range of thickness 0.1-10mum is formed on a forming surface of the die 2 of super hard alloy, etc. Since the coating layer 2a is interposed, the frictional force between the forming surface and the working surface of material to be formed is reduced, generation of the tearing and seizing of the surface to be formed can be prevented securely. As a result, the quality of the working surface of the material 1 to be worked is improved. Further, since the frictional force is reduced, the wall thickness and weight of the material 1 to be formed can be reduced and the cost of the product can be cut down.

Abstract: PURPOSE:To prevent a detachment of an electronic component at the time of bonding and to prevent an impossibility of pick-up of the device at the time of detachment by using such adhesive agent for an adhesive tape that has a sufficient adhesive force till it hardens and then weakens its adhesive force when it is hardened by an irradiation with ultraviolet rays, and detaching the electronic component from the adhesive tape by irradiating the adhesive agent which is bonding the electronic component by the use of ultraviolet rays. CONSTITUTION:A semiconductor element 5 is bonded and fixed to an adhesive tape 3 at regular intervals while being pressed by a pusher 6 one by one and at the same time, the adhesive tape 3 is wound up around a reel. For detaching the semiconductor element 5 in an automatic supplier, an adhesive agent bonding the semiconductor element 5 is hardened by irradiation with ultraviolet rays from an ultraviolet ray projection device 8 and the adhesive force is thus weakened, after which a vacuum chuck 7 sucks the semiconductor element 5 and picks it up. Also, the adhesive agent of the adhesive tape 3 keeps a sufficient adhesive force without hardening before the irradiation with ultraviolet rays. Accordingly, a detachment during a transportation by the automatic supplier and an impossibility of pick-up detachment do not occur.
