Title: Movable barrel driving device
Inventor: SHIRAI HITOSHI
IPC: G03B3/10
Filed: 1983-10-27
Abstract: PURPOSE:To move a movable barrel holding a photographic lens smoothly along a guide member which holds the movable barrel, by applying a driving force for the movable barrel onto the axial line of the guide member or near it. CONSTITUTION:When a cam driving gear 24 is turned by rotation of a motor, a cam driving pin 24c is brought into contact with a right face 61c of a plate cam 61 to turn this plae cam 61 counterclockwise around a cam shaft 62, and therefore, a driving pin 9 is moved left, and a movable barrel part is fed out left. When the motor is rotated in the reverse direction, the cam driving gear 24 is turned in the reverse direction, and therefore, the driving pin 24c is brought into contact with a left face 61d to move the driving pin 9 right. Since a press spring 65 presses and charges the pin 9 at this movement time, the movable barrel part is stably moved freely forward and backward. A fine adjustment screw 68 may be set to a camera body to adjust finely deformation of the plate cam 61 itself and the gap between the plate cam 61 and the cam shaft 62.

Title: Inspection method through foaming by infrared ray
Inventor: MURAKAMI KIMIHIDE
IPC: G01M3/02
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To accurately detect a small leakage part by allowing the temperature of foamed liquid applied to a to-be-inspected object where the inside is pressurized to differ from the temperature of a pressurized gas and extracting a part with a temperature difference from the infrared image on the surface of the inspection object. SOLUTION: For example, the leakage of an inspection object surface 2 on the meld line of a cylindrical container 1 which is pressurized by pressurized air is inspected by applying a foaming liquid at a temperature higher than the temperature of the pressurized air, for example, by approximately 3 deg.C for example by a spray 3. An image picked up by an infrared camera 4 is processed by an image-processing device 5, a part with a low temperature is extracted, and foaming position is displayed on the screen of a monitor 6 or output is made to an alarm lamp 7. Even in the case of a small hole where the diameter of a leakage part is approximately several tens of μm, a foam with a diameter of approximately several mm is generated due to a leaked gas and is identified by a temperature difference.  The temperature difference between the foaming liquid and the pressurized air is preferably about 10 deg.C and a foaming liquid of a lower temperature than the temperature of the pressurized air may be used.
