Title: Atheletic tool for hitting
Inventor: NAKANISHI MOTOYASU
IPC: A63B102/32
Filed: 1987-08-19
Abstract: PURPOSE: To reduce the ball striking vibration ill-influencing the hand palm to a great extent by installing a buffer layer of gel-form substance in a grip part in such a way as consolidated with a base layer made of a foamable synthetic resin, and allowing the buffer layer and base layer to dispersively absorb the impact at the time of striking a ball. CONSTITUTION: A grip part 30 is composed of a base layer 31 of a foamable synthetic resin formed in layers on the periphery of a long shank part 20, i.e., a buffer layer 32 of gel-form substance installed inside the base layer 31 in such a way as separated from the long shank part 20, and a sheath layer 33 covering the outside surface of the base layer 31. When a ball is struck, the impact of ball which is received to the ball striking part 10 is transmitted to the palm as impact vibration, and because it passes through the grip part 30, the palm receives the vibration transmitted to the buffer layer 32 in the form of impact waves.  The gel-form substance to form the buffer layer 32 assumes a non-elastic deformation and does not generate any repulsive resilience, and propagates to a wide area quickly, so that the vibration is absorbed dampedly over the whole area of the gel-form substance, and the remaining portion nevertheless transmitted to the palm is of a very low level and can be converged in a short time.

Title: Dc arc welding machine
Inventor: HAGIWARA SEIGO
IPC: B23K9/073
Filed: 1982-11-25
Abstract: PURPOSE:To decrease the generation of spatter in a DC arc welding machine by increasing an output frequency upon lapse of a specified time after arc generation and increasing gradually the increasing speed of the output frequency in the stage of short circuiting. CONSTITUTION:When a wire is short-circuited to a base material, a switching frequency is gradually increased and the elongation in short-circuiting current is gradually decreased. Since the current at the point of the time when the arc is regenerated is small, pinching force is small and less spatter is formed. The arc current is increased to maintain the period of melting the base material by decreasing the switching frequency for the specified time after the arc regeneration. The frequency is increased to drop sharply the arc current after a specified time. The short-circuiting and the arcing are repeated in the above-mentioned way.
