Abstract: PURPOSE:To form a good deep dead, by setting relative speed of irradiating point and an object to be welded to zero and rapid advancing speed alternately. CONSTITUTION:A laser beam 7 irradiated from a laser beam generator 1 is irradiated onto the weld line 8 of an object 4 to be welded. At the same time, jet gas is blown from an inert gas jetting device 3. Relative speed of the irradiation point 9 and the object 4 is set to zero and rapid advance speed alternately by a welding speed setting device 2. In the process of keyhole making in which the relative speed is set to zero, a keyhole 10 is made on the object 4 by a laser beam 7 at irradiation point 9, and a plasma generating point is introduced into the keyhole 10 temporarily. In the process of irradiation moving in which the relative speed is set to rapid advance speed, the irradiation point 9 is moved rapidly from a point where the keyhole 10 is made to another point on the weld line 8. A bead 11 is formed by repeating these two stages.

Title: Humidifier
Inventor: OKAWACHI YUKIKUNI
IPC: F24F6/04
Filed: 1987-02-10
Abstract: PURPOSE:To reduce the amount of water drained wastefully to a minimum and prevent the reduction in humidification performance by a method wherein the lower part of a drain pipe in a rising gradient is connected to a hollow porous member and at the top part of the pipe a nozzle with a minute drain hole is attached. CONSTITUTION:Water is supplied to a hollow porous member 40 from a water tank 7 and when hot air, etc., are sent from the arrow a direction to the b direction, the water in the member vaporizes to carry out humidification. There by, the water level in the tank 7 is lowered and then a float switch 9 is operated to open a solenoid valve 8 to supply water. As the humidification progresses, the impurity concentration of the water in the member 40 becomes thicker and then the water in the member is gradually drained out into a drain pan in the minimum amount of water through a drain pipe 6 installed in a rising gradient and through the minute discharge hole 11b of the nozzle 11. Thus, the amount of water drained wastefully is reduced to a minimum and the obstruction of drainage function caused by the stagnation of bubbles in the inside does not occur and the impurity contained in supplied water, etc., is discharged and the reduction in humidification performance can be prevented.

Abstract: PURPOSE:To constitute the device so that food can be pulverized to a uniform granular size in a low noise state by providing a V-shaped guide groove provided along the advance direction of a blade-like rotary edge, a cut groove which is provided on its groove bottom and through which the rotary edge passes through a small clearance, and a sieve plate provided on a discharge port. CONSTITUTION:When a motor 5 is driven, a rotary edge 6 rotates, and pulverization of coffee beans which go into a pulverizing chamber 3 is started. In the beginning of pulverization, since a granular size of coffee beans, that is, mass is large, even if the rotary edge 6 rotates at a low speed, the pulverization advances in a space in the pulverizing chamber 3. In such a way, as the granular size becomes fine successively, the coffee beans flow through the surface of an inner wall of the pulverizing chamber 3 by centrifugal force of the rotary edge 6, and are collected in a divided part of a bottom groove of a V-shaped guide group 7 along the V-shaped guide groove 7, cut more finely by edge parts 8a, 8a of the divided part 8 and the rotary edge 6, and when they become a prescribed granular size, discharged to an extracting chamber 12 through a small hole 9 of a sieve plate 10. In such a way, when the pulverization is all completed, the pulverizing operation is switched to a coffee extracting operation.
