Title: Arc spot welding method
Inventor: TABUCHI TSUGIO
IPC: B23K9/007
Filed: 1978-12-13
Abstract: PURPOSE: To achieve the captioned welding of plates stably in a short time, by firing an arc in the atmosphere of active gas or mixture gas containing it in a gap between the electrode and the work, and feeding inert gas in the gap a specified time afterwards.  
     CONSTITUTION: An electrode 2 enveloped in a nozzle 3 is placed on works 1a, 1b laminated together. An arc is fired in the atmosphere of active gas or mixture gas containing it. In this case, active gas, such as nitrogen, oxygen and carbon dioxide, may be replaced by the atmosphere, without requiring particular supply. When a welding voltage is applied between the electrode 2 and the work 1a, an arc 5 is fired. Then, time T 3  later, a shield gas 4 consisting of inert gas is supplied. Since the arc 5 in the active gas is reduced, the penetration may be made deep, and the time T 3  is about 0.01W0.2 seconds, and the inside diameter of nozzle 3 is as small as about 12mm. Hence, the gap between the electrode and the work is stationary, so that a steady shielding gas atmosphere may be achieved.

Inventor: NAKATANI TATSUO
IPC: F24H7/00
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To reduce the deformation of heat-storing material when a load is applied by constituting a latent heat heat-storing body in a heat-storing unit by a bag body where at least the specific number of independent latent heat heat-storing agents is sealed. SOLUTION: A latent heat heat-storing body 3 is constituted by adjoining and arranging latent heat heat-storing body blocks 3A, 3B, and 3C that are bag bodies where three latent heat heat-storing agents are sealed. Then, a thermostat 7 is arranged between SUS plates 8 at the upper part of the latent heat heat-storing body block 3B being arranged at a center part. The latent heat heat-storing body 3 is divided into three, thus allowing the heat-storing agents in the latent heat heat-storing body 3B block being placed at the center part where a load is applied the most to be moved only in the bag body of the latent heat heat-storing body 3B block.  Therefore, the reduction in the thickness of the center part in the latent heat heat-storing 3B block becomes extremely smaller as compared with a case where the latent heat heat-storing body blocks 3A, 3B, and 3C are formed in one piece and heat-storing material can be moved.

Title: Pressure liquid feeding apparatus
Inventor: OOE TAKESHI
IPC: F04B49/00
Filed: 1980-10-31
Abstract: PURPOSE: To reduce the consumption power by selectively feeding the pressure liquid from a plurality of pumps by using a flowing passage switching valve which operates according to the magnitude of the load of a hydraulic equipment and using the flow rate control valve equipped with a droping mechanism.
