Title: Cleaning device movable on wall surface
Inventor: OGASAWARA MASAHIRO
IPC: A47L3/02
Filed: 1992-08-24
Abstract: PURPOSE:To provide flexibility to automatically respond to changes in the contour of the surface of a wall being cleaned and maintain the sucking force of a suction cup invariably at the optimum level by a method wherein a moving means is provided, a suction cup adapted to be held by suction on the wall by negative pressure is further provided and the sucking force of the suction cup is automatically varied according to wall surface flatness signals from a detecting means. CONSTITUTION:When a solenoid valve 22 is activated by a signal from a detecting means 20 to switch its output to a low pressure adjusting valve 23, the compressed air under low pressure is fed to the primary side of an ejector 12 to maintain the inside of a suction cup 4 at a relatively low level of negative pressure. In this condition, a cleaning device movable on wall is supported on the surface of a wall being cleaned by the optimum supporting force caused by the sucking force of the suction cup 4. When the cleaning device 1 is moved in a predetermined direction, the wall surface is cleaned by the wiping action of the suction cup 4 itself or other cleaning means. When the cleaning device reaches a part of the material different from that of the wall surface at a starting point of cleaning, e.g. glass, the detecting means 20 produces the off signal which activates a control circuit to switch the output of the solenoid valve 22 to a high pressure adjusting valve 24, whereby the negative pressure producing force of an ejector 12 is increased to augment the sucking force.

Abstract: PURPOSE: To isolate a high molecular weight double stranded DNA from a cell containing a deoxyribonuclease of high endogenic level, by breaking open the cell, releasing the double stranded DNA, etc., bringing the DNA into contact with a specific aqueous solution.  
     CONSTITUTION: A cell containing a deoxyribonuclease of high endogenic level is broken open to release a double stranded DNA and the deoxyribonuclease. The double stranded DNA and the deoxyribonuclease are brought into contact with an aqueous solution containing (1) a protein denaturing agent capable of denaturing the deoxyribonuclease without denaturing the double stranded DNA and suppressing the activity of the deoxyribonuclease and (2) an agent for suppressing the restoration of the denatured deoxyribonuclease by dissolving a disulfide bond. Then the high molecular weight double stranded DNA is isolated from the aqueous solution.

Title: Premix-type gas turbine combustor
Inventor: YOKOTA OSAMU
IPC: F23R3/12
Filed: 1990-09-19
Abstract: PURPOSE:To make uniform the flow velocity of a premix and the distribution of fuel concentration at a swirler outlet in a premix combustion part, by forming swirler vanes disposed in a swirler of the premix combustion part in the shape of fins, in a multi-nozzle type two-stage combustor. CONSTITUTION:In diffusion combustion 1 in a multi-nozzle type two-stage combustor, a primary fuel ejected from a primary fuel nozzle 3 and primary air 4 are mixed with each other by diffusion, and a flame is formed in a region where the fuel concentration is within a combustible concentration range from a low to a high concentration. In a premix combustion 2, a secondary fuel ejected from a secondary fuel nozzle 5 and secondary air 6 are premixed with each other in a swirler 7, to form a flame at an outlet of the swirler 7. Fin- shaped swirler vanes 8 provided in the swirler 7 in a premix combustion part cause the secondary fuel and the secondary air 6 flowing on the fins to generate swirls at upstream and downstream ends of the fins, thereby accelerating the mixing. It is thereby possible to make uniform the flow velocity of the premix and the distribution of fuel concentration at the swirler outlet, within a short distance and without causing any pressure loss in the premix blowing through the swirler.
