Title: Bag body for air bag
Inventor: SHIGETA SEISABURO
IPC: B60R21/16
Filed: 1990-10-09
Abstract: PURPOSE:To produce an inexpensive air bag imparted with stable and reliable air non-permeability by causing an unwoven fabric to be closely contacted and integrated, by melting, with an inward portion of a bag body prepared by using a synthetic fiber textile as a base member. CONSTITUTION:An air bag body 1 is produced using a laminated cloth sheet which is prepared by laminating a synthetic fiber textile 2a, a polyolefin-based resin film 3, and an unwoven fabric 4 so that they may be located on an outward passenger side of the bag body 1, on an immediately inward side therefrom and on a further inward side therefrom in this order when mounted to a vehicle body. On the other hand, at a vehicle body side, i.e., a side facing a handle, a synthetic fiber textile 2b is used. The resulting lamination at an inner peripheral end portion 6 thereof is unified for bondage by being sewn in plural sewing-strand rows. Further, an inflator mount opening 5 is formed at a central portion of the driver-side textile 2b. According to this structure, the air permeation of the textile is prevented by the polyolefin-based resin film 3. On the other hand, the presence of the unwoven fabric 4 prevents the high-pressure gas during the air-bag system operation from directly impinging upon the polyolefin-based resin film 3 which is therefore prevented from being damaged by a high-temperature gas.

Title: Fish eye inspector
Inventor: KIMURA HIROAKI
IPC: G01N21/89
Filed: 1988-10-27
Abstract: PURPOSE:To achieve accurate detection in the perimeter of a fish eye of a film by specifying a setting angle of a linear transmission lighting with respect to a direction of moving the film to receive a transmission light with a one- dimensional CCD camera. CONSTITUTION:A moving film 2 is lighted with a linear light source 3 and a transmission image is received with a one-dimensional CCD camera 1. Then, a signal of the camera 1 is binary coded and converted to a run length to detect the presence of a fish eye 6. A setting angle of a line of the light source 3 is set below 60 deg. with respect to the direction of moving the film to detect an optical distortion in the perimeter of the fish eye extending parallel with the direction of moving the film. When the setting angle exceeds 60 deg., a density in the perimeter lower so much as to make detection impossible to perform. This enables accurate detection in the perimeter of the fish eye extending parallel with the direction of feeding the film.
