Patent number: 9139219Abstract: Construction is achieved that more completely protects the driver of a vehicle during a secondary collision by gradually increasing the impact load that is absorbed by an energy absorbing member 22b the more the steering wheel displaces in the forward direction. The energy absorbing member 22b comprises a base section 27a that is provided in the center section, and a pair of impact absorbing sections 28b that extend in the forward direction from both ends of the base section 27a and have U-shaped bent back curved sections 29b in the middle section. Of these impact absorbing sections 28b , at least the portions that are nearer the tip end side than the bent back curved sections 29b are pressed so that the height of the energy absorbing member 22b with respect to a stroking section 32 gradually increases going in a direction from the bent back curved sections 29b toward the tip end side of the energy absorbing sections 28b.Type: GrantFiled: August 8, 2012Date of Patent: September 22, 2015Assignee: NSK LTD.Inventors: Seiichi Moriyama, Hiroshi Shibazaki, Kenji Fujikawa, Masajirou Watanabe, Toru Takahashi

Patent number: 4463384Abstract: A television camera having a photo-taking lens, an image pick-up device to take an image of a photographic object formed on its image pick-up surface by the photo-taking lens, a synchronous signal generator to control operations of the pick-up device, and an electronic view finder which displays the photographic object image based on an image pick-up signal obtained by the pick-up device. In this type of camera, there are further provided a detecting device to detect a focussed state of the photographic object image formed on the above-mentioned image pick-up surface, and a pattern generator to generate a pattern signal corresponding to the detected state. On the basis of the synchronous signal from the above-mentioned synchronous signal generator, an output from the pattern generator can be displayed at a predetermined position on the image surface of the above-mentioned electronic view finder.Type: GrantFiled: February 18, 1983Date of Patent: July 31, 1984Assignee: Canon Kabushiki KaishaInventors: Kenji Fujikawa, Ryusho Hirose
