Title: Flow velocity measuring method
Inventor: HAKUSOO CHAN
IPC: G01F1/66
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To stably measure flow velocity even in the case of the distance between opposed transducers being large by measuring flow velocity from the difference between upstream and downstream propagation times of amplitude- modulated ultrasonic wave, and the like. SOLUTION: In a propagation time difference method, flow velocity is measured from the difference between upstream and downstream propagation times of amplitude-modulated ultrasonic wave. In a phase difference method, phase difference between transmitted wave and a signal received after propagated obliquely upstream, and phase difference between transmitted wave and a signal received after propagated obliquely downstream, are measured to compute flow velocity by the difference between the reciprocals of these phase differences regardless of the sound velocity. For instance, transducers 1, 2 are opposedly arranged on both sides of a river, with a distance L at an angle α to a flow velocity direction V. The transducers 1, 2 are alternately switched to the transmit side and receive side by a switching circuit 3.  An amplitude modulator 17 and a carrier wave oscillator 13 are connected to an output amplifier 18, and a modulation signal oscillator 14 and the carrier wave oscillator 13 generate sine waves.

IPC: B23K9/16
Filed: 1984-06-18
Abstract: PURPOSE:To prevent the generation of a defect such as lack of fusion in a weld zone by feeding an inert gas to the inside of a hollow tungsten electrode and controlling the spread of an arc. CONSTITUTION:The inert gas 13 is supplied to the hollow part 12 of the cylindrical hollow electrode 11 and arc welding is executed while the gas is ejected from the arc generating end of the electrode 11.

Abstract: PURPOSE:To provide a method for bending a tube with irregular shaped section, by which the tube with irregular shaped section can be normally bent without being deformed to a flat, and to provide the tube with irregular shaped section, which can be suitably used for this bending method. CONSTITUTION:In a method for bending a tube with irregular shaped section, an outer core 4 is formed by repeating deformed part 2 and nondeformed part 3 alternately in the peripheral direction. It is the method for bending a tube 1 with irregular shaped section, which is made possible to contract a diameter by deforming the deformed part 2 in a direction to which adjacent nondeformed parts 3 approach each other by contracting the diameter. Bending is performed at a state in which a reinforcing material 5 for preventing a deformation is allowed to exist, which blocks that the tube becomes smaller than a specific tube diameter, inside a prearranged position where the tube 1 is bent. Also, in the tube with irregular shaped section, a rib 5 blocking that the tube becomes smaller than a specific tube diameter by abutting each other in the minimum diameter contraction state, is provided projectingly as one body on the inside surface of each nondeformed part 3 of the outer core 4 toward the center of the outer core 4.

IPC: G03B17/04
Filed: 1978-10-13
Abstract: PURPOSE: To make the camera body compact by providing a mechanism which lets the mirror evacuate to outside the photographing optical path in cooperation to the collapsing operation of the photographing lens.  
     CONSTITUTION: When a photographing lens 2 is pushed backward in the optical axis direction by hand after photographing so as to collapse into the camera body 1, a slide member 41 slides and shifts backward by overcoming the force of a spring 43 mounted to an auxiliary plate 42. Along with the shifting of this slide member 41, a mirror up lever 30 turns counterclockwise and the mirror 20 slides upward in the clockwise direction on a slide surface 31 by overcoming the force of a spring 23. The sliding of this guide rod 22 on the lever causes the lever 30 to raise the mirror 20 to outsid the photographing optical path. At the same time, a switch 44 goes OFF and the lock of a release button 47 is released. In this way, the photographing lens 2 may be collapsed in the camera body and therefore the camera body may be made compact.
