Title: Combustion furnace nozzle device
Inventor: HORII KIYOYUKI
IPC: F04F5/46
Filed: 1986-05-06
Abstract: PURPOSE:To reduce a pressure loss in supplying fuel and improve an efficiency of a combustion furnace by a method wherein a Coanda spiral flow generating part including means for supplying pressurized fluid to a fine clearance arraged at a cylindrical pipe and means for supplying fuel fluid to an inlet port for fuel fluid is arranged. CONSTITUTION:Air and water acting as pressurizing fluid are fed at high speed from a fine clearance 3 into a cylindrical pipe 2. Fluid at an outlet of the fine clearance 3 may form a flow line alpha from the cylindrical pipe to a line passage 1 under a Coanda effect, resulting in that a negative pressure area is generated at an opposite side. Fuel fluid flows from an external part to the negative pressure area (arrow beta). A motion vector of the fluid from the fine clearance 3 and another motion vector of fuel fluid from external side are combined to each other to form fluid flow advancing in the cylindrical pipe toward the line passage 1. The fluid flow is gradually reduced in its diameter and during this process its radial vector is applied. This vector is converted into a circulating vector to generate a spiral motion together with a straight forwarding vector. In this way, as the fuel fluid is transferred to an outlet of nozzle through the Coanda spiral flow, a nozzle part 10 may discharge the fuel fluid into a combustion furnace.

Filed: 1982-06-16
Abstract: PURPOSE:To change leverage with loading condition by providing two reaction transmitting memebers making reaction act on a reaction lever on an output member to make these action points different from each other. CONSTITUTION:Reaction from a master cylinder is normally transmitted to a reaction lever 19 through a reaction plate 20 of an output member 18 and a first reaction transmitting member. An action point is then G. However, when loaded weight is relatively large, a leverage change-over switch is changed over to supply current to and rotate a motor 22 for a predetermined time. Then a worm wheel 24 and an output member 18 rotate. Then a reaction plate 27 of a second reaction transmitting member threaded into the output member 18 moves in the direction of arrow and contacts the reaction lever 19 at a point K, while the reaction plate 20 is separated from said lever 19. Thus, the reaction acting point is changed over from G to K so that the leverage is enlarged.

Title: Chrominance carrier signal control circuit of encoder
Inventor: FUNO SHINJI
IPC: H04N9/74
Filed: 1984-05-21
Abstract: PURPOSE:To always keep the relative ratio of each chrominance carrier signal of both constant by detecting a burst signal in a fluctuated video signal from a circuit without any ACC circuit and controlling the level of a carrier signal being an encoder output through the control voltage generated based on the signal as a reference. CONSTITUTION:An output of a burst detecting circuit 2a, that is, a burst signal is amplified and fed to a DC control voltage generating circuit 5. First, the signal is conductive at a burst positive half cycle at a diode 5a, charged in a capacitor 5b and becomes a control voltage. Then the signal is amplified by a DC amplifier 5c and fed to an amplifier 6 with control terminal. Thus, the chrominance carrier signal level of the encoder output is increased/decreased so as to keep the relative ratio of the chrominance carrier signal level of the video signal constant. When the input signal is a video signal only at an encoder output, the said control voltage is increased to +B power voltage forcibly by the control stop circuit 7 by using a positive video signal (not shown) from the input terminal 8 and stops the control circuit 6.

Title: Production of welded pipe having high flatness of inner surface
Inventor: SHUDO TSUTOMU
IPC: B21C37/08
Filed: 1994-04-18
Abstract: PURPOSE: To substantially eliminate a remaining toe line and improve the flatness of an inner surface by butt-welding both end parts in the width direction of a sheet material formed in cylindrical shape with high frequency induction heating, cutting it so as to give a specific projecting height of the back bead projecting in the pipe and then subjecting to drawing. CONSTITUTION: The welded part formed by the high frequency welding has beads projected from the outer surface and the inner surface of a base material 2. In order to form the excellentt flatness in the following drawing process, the projecting height of the back bead 3 is set in the range of -0.2-+0.3mm. At the time of setting the cutting size in this range, the cutting work is facilitated without giving the excess load to a cutting tool. In the successive drawing it is necessary to set the thickness reduction rate to >=10% in order to improve the flatness on the inner surface of the pipe particularly at the boundary between the welding part 1 and the base material 2. Such a working extent is effective to harden the inner surface of the pipe and to improve the wear resistance.

Abstract: PURPOSE:To reduce the development cost by dividing a pattern into n-set of blocks in the horizontal direction, separating a video signal of each block and applying time expansion to apply parallel processing to the n-set of video signals, applying time compression to the n-set of video signals and synthesizing them. CONSTITUTION:A time expansion circuit 2 applies separation and time expansion to a video signal of a left picture, a time expansion circuit 3 applies separation and time expansion to a video signal of a right picture and video signals of the left and right pictures are processed in parallel. The data of the video signals of the left and right pictures are written in a memory based on a high speed clock sampling a broad band video signal W and read from the memory at a low speed clock being the frequency division of the high speed clock and the video signals of the left and right pictures are subject to separation and time expansion to obtain parallel video signals R, L. Since the video signals R, L are subject to time expansion, the speed required for the video signal processing circuits 5, 4 is halved and the circuits and an LSI used for the image pickup device of the standard television system are used in common. Thus, the development cost is reduced.
