Title: Target tracking device
Inventor: TOGANO KAZUTOSHI
IPC: G01V8/10
Filed: 1990-07-16
Abstract: PURPOSE:To easily attain the operation in a short time with a target tracking device by varying automatically a gate size, setting automatically a threshold level and the polarity, and limiting the manual operations to only the catch of a target at the center of a screen, the start of variation of the gate, and the fixing of the gate. CONSTITUTION:A gate size varying means 31 varies and displays automatically and repetitively the size G of a gate that prescribes an image processing range. An operating means 32 catches a target T at the center of a screen 30 with a manual operation before starting the tracking of the target T and at the same time starts the variation of the size G via the means 31 to fix an optional size G. A threshold level/polarity setting means 33 sets automatically a threshold level and the polarity at binarization for extraction of the target T after the size G is fixed by the means 32. Thus such preparatory operations can be attained easily and in a short time before tracking the target T as the catch of this T, the setting of the gate size, the setting of the threshold level for binarization, etc.

Title: Grinding wheel
Inventor: NAGANAMI NORITAKA
IPC: B24D3/22
Filed: 1983-10-06
Abstract: PURPOSE:To prevent a grinding burn and a grinding crack from being caused even if dry grinding is performed, by holding abrasive grains with lubricating materials by a polyurethane rubber bond, in the case of a grinding wheel suitable for grinding a grind-difficult material. CONSTITUTION:A cup-shaped metallic bed 1 provides on its upper surface 1a a circular annular groove 1b in which an abrasive grain layer 5 in a predetermined thickness is formed. This abrasive grain layer 5, after dispersing diamond abrasive grains 2 with lubricating materials 3 in the groove 1b and injecting a liquid state polyurethane rubber bond 4 to be hardened, is protrusively formed by scraping off the upper surface 1a of the bed 1 to the predetermined height from the bottom surface of the groove 1b. In such way, the grinding wheel, never causing a grinding burn and a grinding crack due to grinding heat even if a grind-difficult material such as titanium nitride system cermet is dry ground, reduces the resistance applied to the abrasive grain layer, enabling the continuous grinding even without performing dressing work further improving grinding ratio.

Title: Magnetic bearing device
Inventor: KAMIYAMA HIROTOMO
IPC: F16C32/04
Filed: 1994-08-09
Abstract: PURPOSE:To obtain a magnetic bearing device which enables higher speed rotation by arranging a radial displacement sensor and an axial displacement sensor in a superposing manner in at least their one portions in an axial direction of a rotary shaft, and thereby enlarging a load capacity of the bearing. CONSTITUTION:An axial displacement sensor 5b an a radial displacement sensor 4b are arranged superposingly in an axial direction of a shaft 2, so that an arrangement spase for the sensors is saved in an axial direction. The axial measurement of the shaft 2 can be reduced. As a result, characteristic frequency of the shaft 2 is increased, and higher speed rotation is enabled. The axial displacement sensor 5b can be arranged in the vicinity of a radial magnetic bearing device 6 compared to a conventional case, so that detection error of the axial displacement sensor 5b due to the influence of inclination of the shaft 2 is minimized. It is thus possible to perform axial control with higher accuracy. Margin of an axial measurement is utilized for a suctioning area of the magnetic bearing, so that a load capacity of the bearing is increased.

Title: Optical recording medium
Inventor: NISHIMURA YUKIO
IPC: G11B7/24035
Filed: 1985-08-27
Abstract: PURPOSE:To provide a high-density high-sensitivity recording medium, by cyclically building up monomolecular films of a diacetylene derivative compound and monomolecular films of an azulenium salt compound. CONSTITUTION:When the optical recording medium 20 comprising a hetero built-up film 16 is uniformly irradiated with UV rays, the diacetylene derivative compound 13 is polyerized to be a polydiacetylene derivative compound, so that the color of each recording layer consisting of the monomolecular film of the compound 13 is changed to blue, which corresponds to a maximum absorption wavelength of 620-660nm. This change is irreversible. Then, with a predetermined part of the recording medium (hetero built-up film) 16 irradiated with a semiconductor laser beam (wavelength: 800-850nm), the irradiated parts of each radiation-absorbing layer are heated due to absorption of the laser beam 19. The corresponding parts 20 of the recording layer 17 making contact with or adjacent to the heated parts of the radiation-absorbing layers are also heated to or above 50 deg.C through conduction of heat, accompanied by a color change to red, which corresponds to a maximum absorption wavelength of 540nm. This change is also irreversible. Accordingly, recording can be performed by utilizing the color change at predetermined parts of the recording layer according to input information.
