Title: Seat belt retractor
Inventor: FUJIMURA KOICHI
IPC: B60R22/40
Filed: 1991-03-11
Abstract: PURPOSE:To provide a light and low-cost seat belt retractor. CONSTITUTION:When deceleration exceeding a given value is exerted on a vehicle, reel shaft 4 is rotated, as shown by a two-cot chain line, around the end of a first protrusion shaft 4b, loosely engaged with an output shaft 20, by means of the pull-out force of a seat belt. This rotation causes rotation of a ratchet 13 to a tooth 9a of a circular hole 9 and engagement of a tooth 13b of a ratchet 13 with the tooth 9a of the circular hole 9. As a result, rotation in the seat belt pull-out direction of the reel shaft 4 is blocked, and pull-out of the seat belt 3 created as a result of a driver being about to move forward owing to inertia is reliably blocked. As a result, the driver is reliably constrained for protection. Further, a stress generated at the tooth 9a at a current time is relaxed and not increased to so high value because of width T of the tooth 9a being increased by a burring work.

IPC: B23K9/073
Filed: 1979-04-16
Abstract: PURPOSE: To prevent occurrence of arc between electrodes and realize stable welding, in multiple electrode welding, by setting one electrode in reverse polarity and the other one in positive polarity, and controlling the direction of currents flowing into each electrode within the same time always in the same direction.  
     CONSTITUTION: Transistor element groups 2, 2' are connected parallel to welding power sources 1, 1', and the welding currents flowing into the transistor element groups 2, 2' are determined by current control circuits 5, 5'. The currents flowing into the transistors are controlled to welding current waveform D by means of polarity changing elements 4, 4' composed of thyristors 3, 3', and an arc is fired between nonconsumable electrodes 6, 6' and base metal 7. When the polarity of each electrode is different, conventionally, arcs were fired between the electrodes, so that welding was previously impossible. In this method, on the other hand, the directions of current flowing into electrodes within the same time are constant, and arc is not fired between electrodes 6, 6', so that stable arc firing between the electrodes 6, 6' and base metal 7 may be enabled.
