Title: Focusing attachment lens
Inventor: KANEKO MASANOBU
IPC: G02B23/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To enable continuous focusing operation over a wide range while suppressing the moving amount of a focusing lens group to be small by performing focusing operation from an object at infinity to an object at the closest distance by moving a first lens group having a negative refractive power to the object side. SOLUTION: A light ray from an object P becomes a light ray parallel to the optical axis through a focusing attachment lens 1 composed of a first lens group L1 of a negative refractive power and a second lens group L2 of a positive refractive power and is made incident on a telescopic optical system 2 in the focusing state to an object at infinity. By moving the focusing lens group L1 to the object side by δ1 the telescopic optical system 2 on which the focusing attachment lens 1 is mounted is focused from an object at infinity to an object at the closest distance. By moving an objective lens 3 to the object side by δ2 or an eyepiece lens 5 to the side of an observing eye, the telescopic optical system 2 on which the focusing attachment lens 1 is not mounted is focused from an object at infinity to an object at the closest distance.

Title: Capping method and capping apparatus
Inventor: KITAMOTO HIROAKI
IPC: B67B3/20
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To accurately judge a seating point regardless of solid difference between a cap and a container or whether the container is wet or dry. SOLUTION: A rotary encoder 6 is attached to a torque motor 3 to input one pulse to a control device 8 at each time when the torque motor 3 is rotated. The output torque at a time when the torque motor 3 is rotated is detected by a torque detector 7 to be inputted to the control device 8. When a control part 8A drives the torque motor 3, an operation part 8B calculates the change quantity of the output torque per a unit angle of rotation and a comparing part 8C compares this change quantity with a predetermined reference value. At a point of time when the change quantity exceeds the reference value, the control device 8 judges that the upper end of the mouth part 1a of the container becomes the seating point brought into contact with the packing 9 in a cap 5 and seams the cap 5 by a predetermined angle of rotation from this point of time to stop the operation of the torque motor 3.

Title: Magnetic laminated body, its manufacture, and manufacture of magneto-resistance effect element
Inventor: ARAKI SATORU
IPC: H01F10/26
Filed: 1991-09-06
Abstract: PURPOSE:To obtain a magnetic laminated body which shows a large magneto- resistance change and can change the intensity of its operating magnetic field showing a big magneto-resistance change by piling up magnetic thin films containing one or more kinds among Fe, Co, and Ni and Ag thin films on a single-crystal-like buffer layer containing one or more kinds among Ag, Au, and Cu, and so on. CONSTITUTION:This magnetic laminated body is composed of a multilayered film 2 formed by piling up magnetic thin films containing at least one or more kinds among Fe, Co, and Ni and Ag thin films on a single-crystal-like buffer layer 1 containing at least one or more kinds among Ag, Au, and Cu. For example, after an Ag buffer layer 1 having a thickness of 739Angstrom  is formed on a MgO (100) single-crystal substrate 3, the surface of which is polished to a mirror surface, by an MBE method, the crystal structure of the layer 1 is improved to a single-crystal state by annealing the layer 1 in a superhigh vacuum tank. Then, the multilayered film 2 is formed by alternately forming by magnetic Co thin films having a film thickness of 6Angstrom  and Ag thin films having a film thickness of 21Angstrom  30 times by vapor-deposition by using the MBE method.

Title: Method for preventing corrosion of low-level waste liquid treating system
Inventor: TAKAHASHI MASANORI
IPC: G21F9/08
Filed: 1988-10-12
Abstract: PURPOSE:To safely and efficiently suppress the corrosion of equipment by providing a sealed ray source around or in the equipment. CONSTITUTION:A waste nitric acid soln. receives radiation decomposition to form NO2 and HNO2 by the radiations generated from the sealed ray source 8 provided in or around the equipment. The highly oxidative fission products (FP) such as ruthenium tetraoxide formed by the oxidizing power of high-temp. and high-concn. nitric acid are reduced by the reaction effected with the HNO2 formed by the radiation decomposition of the aq. nitric acid soln. thereof at a high rate, by which the corrosion accelerating effect thereof is lost. NOx in general turns to NO2 in a gaseous phase and the NO2 decomposes in an aq. soln. to form nitrous acid. Conversely, the nitrous acid in a liquid phase migrates into the gaseous phase, thus forming the gaseous NOx. The irradiation of the waste nitric acid with radiations, therefore, generates the effect similar to the effect obtd. by adding the NOx from the outside. The stationary formation of the nitrous acid in the waste liquid is enabled by providing the ray source 8 to the inside or outside of the equipment in this way, by which the formation of the highly oxidative FP is suppressed.
