Title: Detector for falling-off of grate bar in sintering machine and equipment therefor
Inventor: SATO HIDEAKI
IPC: F27B21/14
Filed: 1994-03-28
Abstract: PURPOSE:To keep the operation from disturbance, etc., by a method wherein when a grate bar provided on a pallet of a sintering machine falls off, the falling-off is detected through displacement of a striker and according to the result of the detection the operation is controlled until the spot of the falling-off reaches a place for replacing the grate bar. CONSTITUTION:A pallet 23 of a sintering machine has many grate bars for loading of material for sintering and sucking in of air for combustion. When a grate bar falls off, a contact ring 4 of a falling-off detector falls in at the spot of the falling-off and a striker 1 turns in the direction opposite to that of the traveling pallet 23 under springy force of a spring 6. As a result, the end 1a of the striker 1, positioned opposite to the contact ring 4, touches a limit switch 5 so that a signal denoting the falling-off is transmitted. On the basis of the falling-off signal a calculator 7 calculates the time required before the spot of the falling-off reaches a place for replacing the grate bar. Then a stop command is transmitted from a pallet-movement controller 8 to a pallet- driving gear 9 according to the calculation signal.

Abstract: PROBLEM TO BE SOLVED: To simply increase a search speed by making a thread voltage at the time of driving only a thread feed means different from a thread voltage at the time of simultaneously driving the thread feed means and a lens kick means. SOLUTION: When a lens kick search is required in accordance with the decision result, data for setting a thread voltage V1 is transferred to a control unit 7 from, for example, a system controller, and a search command is issued to search a target track by lens kick control. By this issue, a kick pulse is impressed upon a pickup unit by the control unit 7, and a thread motor 8 is driven by the voltage V1 while a lens system 5 is controlled. On the other hand, when the lens kick search is not required but the thread search, the command of a target recording track search is issued by thread feed control. The thread voltage is impressed upon the motor 8 by the control unit 7 to move the unit 4 at high speed.

Title: Energy multiplying device for liquid by means of flow pipe
Inventor: SATOU YOSHIO
IPC: F03B17/00
Filed: 1982-04-08
Abstract: PURPOSE:To multiply a pressure energy by a method wherein the area of the flow path of the flow pipe for the liquid is expanded gradually along the direction of the flow thereof and a pipe to flow the liquid into reverse direction is provided at a position whereat the area of the flow path is expanded sufficiently. CONSTITUTION:In case the flow path is widened gradually from the flow path 1, the pressure energy of the flowing liquid is gradually increased by Bernoulli's principle and the velocity energy thereof is decreased, therefore, the liquid is passed through the flow path 5 and arrives at the flow path 6. When the pressure in the flow path 4 is impressed to the part of the flow path 6, the liquid pressure at the flow path 6 becomes same as the pressure at the flow path 4. Accordingly, the flow path 5 delivers the pressure only and the liquid therein will never flow substantially. As a result, the pressure energy is increased in the flow path 6, therefore, the pressure energy of the liquid is increased further when the liquid flows through the flow pipe 2 and, consequently, the pressure energy is increased further in the flow path 4.
