Patent JP-S551216-A (JP)
Title: Icebreaker
Inventor: KAWANO HAJIME
IPC: B63B35/12
Filed: 1978-06-16
Abstract: PURPOSE: To produce longer cracks in ice through shocks given by an icebreaker's bow and effectively break ice, by projecting a support frame in front of the bow and discharging refrigerant from its tip to the ice plate right before breaking for  generating thermal stress in the ice.  
     CONSTITUTION: A refrigerant injector 6, movable vertically and back and forth by means of a hydraulic cylinder 12, is extended from the icebreaker's bow through a support arm 7. Refrigerant 10 such as liquid nitrogen in a storage tank 9 is discharged from the injector 6 through a pump 11 and pipe 8. The ice plate 2 injected with the refrigerant 10 generates local tensile thermal stress due to cooling, which produces much longer cracks than those caused by conventional icebreaking methods when the bow of icebreaker 3 strikes against the ice, thus the icebreaking is very effective.

Title: Welding method using laser beam
Inventor: USHIMI KENJI
IPC: B23K26/21
Filed: 1980-05-31
Abstract: PURPOSE:To weld the 2nd member, to fill a spacing, to prevent residual stress and to improve productivity by holding the 2nd member at a prescribed spacing to the 1st welding member, and irradiating laser beam from the 2nd member side. CONSTITUTION:A conductive member which is the 2nd welding member 3 is opposed to above the grid electrode of an electron gun as the 1st welding member 1a. The opposing spacing is held at below the thickness of wire diameter of the member 3 by a suitable means. Thence, the joining part 3a of the 1st, 2nd members 1a, 3 is irradiated by laer beam L from above the 2nd member 3. Then, the irradiated part of the 2nd member 3 melts and produces a keyhole, through which hole the laser beam L melts the 1st member 1a, and the molten metal of the 2nd member 3 fills the spacing, thereby surely coupling the 1st, 2nd members 1a, 3 without generating any residual stress.

Title: Corona discharger
Inventor: MASUDA SENICHI
IPC: H01T19/00
Filed: 1985-04-05
Abstract: PURPOSE:To perform uniform corona discharge even when a corona discharger is heated up to >=150 deg.C by using metal which has a low sputter rate in a helium atmosphere for the surface of a discharging electrode. CONSTITUTION:At least the surface of the discharging electrode 3 is made of the metal whose sputter rate is <=0.3 in a helium atmosphere. There are W, Pt, Mo, Ta, Ir, etc. as the metal. Specially, Pt, W and Mo are preferable because a metallic coating is easily formed on the surface of the discharging electrode made of another material by electrolytic or electroless plating. Consequently, the corona discharge in a heated state is not disturbed by the scatter of the metal on the surface of the discharging electrode or the exposure of base metal, so that the corona discharge has high uniformity.

Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent entry of foam into an overflow pipe and reduce the necessary height of an absorption tower without degrading the function of the overflow pipe by providing spray nozzles near the overflow pipe and spraying a liquid onto a liquid surface near the overflow pipe, thereby removing the foam. SOLUTION: In the case an overflow pipe 7 is attached to an absorption tower 1, nozzles 10 are provided on both sides of the entrance of the overflow pipe 7, piping 11 is connected to each of them, and pressurized water is supplied from the piping 11. The nozzles 10 are arranged so that the sprayed liquid covers a liquid surface in front of the entrance of the overflow pipe 7. From the nozzles 10, the water is sprayed onto the liquid surface around the overflow pipe 7, thereby breaking foam 9 occurring on the liquid surface. This prevents the foam 9 entering the overflow pipe 7. On the other hand, because the nozzles 10 are arranged on both sides of the overflow pipe 7, outflow from the overflow pipe 7 is not hindered when the liquid surface rises.
