Title: Method and device for cutting inside surface of hollow shaft, and servo machanism for said method
Inventor: ONO HIROYUKI
IPC: B23B41/06
Filed: 1978-07-10
Abstract: PURPOSE: To cut the inside surface of a hollow shaft to a desired form, by swinging a tool by a slope of a wedge member to control the feed of the tool.  
     CONSTITUTION: A pipe 6 is inserted into a premachined hole 5 of the hollow shaft 4 so that the nose 11c of the tool 11 is located in the cuitting start position 5P of the premachined hole. The hollow shaft 4 is rotatably supported on roll rests and chucked so that the shaft 4 is rotated centering the hole 5. At the same time, the pipe 6 is moved toward its butt 6B by a servo mechanism to cause relative spiral motion between the nose 11C and the hole 5. The inside surface of the shaft is thus cut. The wedge member 14 is moved back and forth along the pipe 6 by the servo mechanism to feed the nose 11C by quantity for the desired form S to the provided on the inside surface.

Title: Lens barrel
Inventor: SUGANO HIDEO
IPC: G02B7/04
Filed: 1995-04-10
Abstract: PURPOSE: To attain smooth meshing and to reduce noise etc., at the time of driving by providing a decelerating mechanism with an external-tooth small gear to which the rotation of a driving force transmission shaft is transmitted and an internal-tooth large gear meshing with the small gear. CONSTITUTION: When a coupling shaft on a camera body side is rotated, a coupling shaft 7 transmitting the rotation to an interchangeable lens for single lens reflex camera 100 is rotated, whereby the small-diameter gear 7a set at the front part of the coupling shaft 7 is rotated. Since the gear 7a is meshed with the internal-tooth large-diameter gear 5b set at the rear part of a reducing gear 5, the gear 5 is also rotated. The gear 7a is equivalent to an external-tooth driving gear. The gear 5b is equivalent to an internal-tooth input gear. When the gear 5 is rotated, a focusing ring 2 is rotated centering around an optical axis A because the small-diameter gear 5a at the front part of the gear 5 is meshed with a segment gear 2c set on an inner periphery side of the tail part of the focusing ring 2.

IPC: G21B1/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To shorten the time necessary for decontaminating and simplify the device constitution. SOLUTION: Heavy water (containing tritium water) adhered on the inner surface of pipe 1 contaminated with tritium is evaporated and removed by dry air heated with a heater 3 which is supplied from a pipe 10 into a pipe 1.

After finishing drying work of the pipe 1, air containing steam of light water is taken from a pipe 13 and supplied to the pipe 1. The tritium contained in heavy water adsorbed on the pipe 1 inner surface is exchanged by isotope of hydrogen and removed from the pipe 1 inner surface. The steam of light water and tritium water is cooled by the condenser 4 and removed as water. As the dried air and air containing steam of light water are below 200 deg.C, the tritium solid-solved in the pipe 1 is enclosed in the pipe 1.
