Title: Welding method of pipe member and flange member
Inventor: NISHIMOTO TOKUAKI
IPC: B23K11/00
Filed: 1983-08-24
Abstract: PURPOSE:To perform expanding at the open end of a pipe member simultaneously with welding in the stage of welding the pipe member and the flange member by tapering the tip of a movable electrode at a specific angle. CONSTITUTION:A pipe member 2 is inserted into a flange member formed with a hole 1a having a tapered part 1b on one side and the open end of the member 2 is expanded and is resistance-welded to the member 1. A tapered part 4a is formed to a movable electrode 4 of a stationary type resistance welding machine 3 and is set at the angle steeper than the angle of the tapered part 1b. The member 2 is then clamped between stationary electrodes 6a and 6b and the member 2 and the hole 1a with the tapered part 1b fitted upward are placed on the electrodes 6. The electrode 4 is lowered and is actuated initially under small pressing force to expand the open end of the member 2. Small current is passed during such expanding to preheat the member and to accelerate expanding. The member 2 expanded in this stage makes linear contact with the tapered part 1b. The pressing force and current are thereafter changed over to large power and large current and the annular contact parts of the members 1, 2 are resistance- welded.

Abstract: PURPOSE:To suppress over-correction or under-correction respectively by means of feedback so as to prevent hunting, etc., by lowering converging speed of feedback for controlling an air-fuel ratio when a detection value of the air-fuel ratio is out of a specified range being capable of maintaining a specified control model. CONSTITUTION:Fuel is supplied to air which is supplied to an internal combustion engine M1 by a means M2 so as to generate air-fuel mixture supplied to the internal combustion engine M1. On the other hand, an air-fuel ratio of the air-fuel mixture is detected by a means M3 based on exhaust gas of the internal combustion engine M1. An air-fuel ratio corrective coefficient for each case is calculated by a means M4 while executing feedback for controlling the detected air-fuel ratio to a target air-fuel ratio. Further more, a supplied fuel quantity is controlled by a means M5 according to the air-fuel ratio corrective coefficient. By this constitution, it is judged by a means M6 whether a detection value of the air-fuel ratio is in a specified range in which maintainauce of the specified control model is practicable. The feedback is gradually converged when the detection value is out of the specified range.

Title: Centrifugal pump
Inventor: TANAKA TEIJI
IPC: F04D29/22
Filed: 1989-06-21
Abstract: PURPOSE:To prevent increase of leak even if size of clearance in a seal section is changed by providing an opening in the axial direction on the inlet side of a cylindrical section of an impeller side plate at the circumferential position and a wearing ring on the inner diameter side of the cylindrical section of the impeller side plate. CONSTITUTION:Since pressure loss occurs at the inlet of a seal section when ordinary clearance is provided in the seal section, pressure on the inner diameter side of cylindrical sections 2a, 2b of an impeller side plate becomes lower than that on the outer diameter side, and a flow which passes through openings 5a, 5b flows toward inside. This flow becomes resistance against a leak flow 8 which passes through the seal section, thereby decreasing leak flow rate. On the other hand, when clearance in the seal section is expanded due to wear, reduction of pressure from the outer diameter of the cylindrical sections 2a, 2b of the impeller side plate to the inner diameter decreases. Consequently, centrifugal force which acts on fluid in the openings becomes predominant due to the rotation of an impeller 2, and the flow which passes through the openings 5a, 5b flows toward outside. That is, a portion of the leak flow 8 becomes a bypass flow 9, thereby reducing the amount which flows toward the suction side of the impeller.
