Title: Adhesion method of foil for air bearing
Inventor: NAGATANI KIYOSHI
IPC: G11B15/60
Filed: 1978-07-05
Abstract: PURPOSE: To cause a foil for air bearing to adhere onto the tape wound core cylinder surface cheeply in simple method and equipment by making the tape wound core cylinder surface of an uneven face such as aventurine lacquer by the mechanical bump of macadam particles in the rotary head-system magnetic tape device.  
     CONSTITUTION: Macadam particles 11 such as native Al 2 O 3  supplied from arrow 10 are jetted into a mist from nozzle 9 in a high speed by the compressed air supplied from arrow 12 and bump mechanically cylindrical surface of the tape wound core cylinder and make surface 5 of an uneven face such as aventurine lacquer. Bumped particles 11 are not stuck and left on surface 5 but are stored in macadam particle collection box 13 to be sent to nozzle 9 circularly. Next, surface 5 is washed simply and is caused to adhere to a static pressure-type air bearing foil, which has the adhesion face subjected to the forming processing, by an epoxysystem adhesive. Thus, it is unnecessary to coat surface 5 with alien materials, and the change of the outside diameter is not generated.

Filed: 1986-04-11
Abstract: PURPOSE:To make a photographer recognize impossibility of focusing in the early stage, by providing a means which reports impossibility of focusing if focusing due to driving of a focus ring is impossible in an auto-focus mechanism. CONSTITUTION:The output signal of a CCD focus sensor 1 is supplied to an interface circuit 8 and is converted to a digital signal by an A/D converting circuit 16 in the circuit 8 and is supplied to a microcomputer 9. The microcomputer 9 detects the position of a photographic lens and operates a required extent L of driving of the focus ring. An extent 'l' is calculated by which the focus ring can be rotated from the measured position of the focus ring until coming into contact with a stopper. If the extent 'l' is smaller than the extent L as the result of comparison between them, it is judged that it is impossible that the focus ring is driven to the in-focus position. In such a case, an LED lighting circuit 14 is operated by the signal of the microcomputer 9 to light an LED 15.
