Title: Lens barrel
Inventor: KONO TAKAHIRO
IPC: G02B7/04
Filed: 1991-09-11
Abstract: PURPOSE:To decrease noise caused by vibration noise by plurally providing a belt-like recessed part or a projecting part in a direction orthogonally crossing with an optical axis on the peripheral surface of a relay holder by which a lens barrel main body is connected with a mount. CONSTITUTION:When a driving mode 6 for focusing and a driving motor 7 for zooming are driven, the vibration A occurs on the front part of a fixed barrel 8 and the relay holder 1 by the driving. The belt-like recessed groove 1a is provided on the outer periphery of the relay holder 1 by which the lens barrel main body including moving optical systems L3 and L4 is connected with a mount 5 on the lens barrel side attached to a camera main body. And the belt-like recessed groove 1b is provided on the inner periphery of the relay holder 1 in a state where its position is shifted from the recessed groove 1a toward an optical axis. Thus, a vibration transmitting path 1-1 is rugged, so that the strength of the vibration A is naturally weakened when it is transmitted. As a result, the transmission of the vibration noise to the camera main body is decreased, so that the occurrence of the noise on the camera main body is decreased.

Title: Optical fiber probe
Inventor: TATEISHI FUMIKAZU
IPC: G02B6/10
Filed: 1988-10-14
Abstract: PURPOSE:To suppress heat generation and to prevent the burn of an optical fiber by forming an antireflection film coating on the inner side of a diamond window. CONSTITUTION:The diamond window 5 which is disposed behind the exist end of the infrared ray optical fiber and allows the transmission of CO2 laser light emitted from the infrared ray optical fiber 4 is provided with the antireflection film coating consisting of lead fluoride on the inner side alone. A cylindrical member 6 made into a cylindrical shape holds the window 5 and the exit end 4a of the infrared ray fiber 4 in place. The infrared ray laser light emitted from the fiber 4 is emitted to the outside through the diamond window 5 disposed behind the exit end 4a of the optical fiber. Since the antireflection film coating 7 is applied to the inner side of the window 5 as mentioned above, the reflection of the laser light by the window 5 is decreased and the resultant generation of the heat is suppressed. The burn of the optical fiber is thus prevented.
