Title: Apparatus for measuring inclining amount of hub of tape cassette
Inventor: KOSEKI TSUTOMU
IPC: G11B23/00
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To measure the inclining amount of a hub at the rotating time in real time, by detecting a signal from an eddy current type detector arranged a predetermined distance from an end face of a metallic jig which is parallel to the hub when the hub is mounted, and calculating the inclining amount of the hub. SOLUTION: A metallic jig 6 of iron, stainless or the like is fitted via a hole 22 to a hub 21 at the take-up side of a tape cassette 2 loaded on a driving means 3. The hub 21 is rotated by driving of a driving shaft 32. An end face 61 of the metallic jig 6 is formed to be parallel to an end face of the hub 21. Three eddy current-type displacement sensors 4A, 4B, 4C are arranged via a predetermined distance from the end face 61. When a high frequency current is fed to an internal coil of each displacement sensor, the sensor forms a high frequency magnetic field and outputs a signal because of an eddy current generated if the end face 61 is present. An operating means receiving the signal calculates the inclining amount of the hub. The inclining angle of the rotating hub can thus be measured in real time.

Title: Method for removing nitrogen oxides and device therefor
Inventor: TSUBOGAMI HARUHIKO
IPC: B01D53/77
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To efficiently remove NOx in gas by sticking water to the surfaces of stainless steel fibers, bringing the NOx-contg. gas into contact with the water and absorbing the NOx in the water. SOLUTION: Stainless steel fibers are laminated in a specified thickness so as to attain a specified packing density and the resultant laminate is wound to form a cylindrical filter element as a vaporliq. contact layer 6. Tap water is sprayed on the surface of the layer 6 with a sprayer 7 to keep the layer 6 always wet. When NOx-contg. gas (g) is introduced into a reactor 4 from the introducing hole 2, it penetrates into the vapor-liq. contact layer 6 from the peripheral surface of the layer 6. During this time, the gas (g) is subjected to anodic oxidation on the fibers 18 and the NOx is absorbed in the tap water sticking to the surfaces of the fibers 18 by contact. The NOx in the gas (g) is efficiently absorbed and removed.

Moreover, while NH3 is supplied together with the carrier gas H2, temperature is then lowered again to form an n-type GaP layer 13. Finally, supply of NH3 is stopped, Zn is supplied together with the carrier gas H2 to form a p-type GaP layer 14 in view of forming a GaP light emitting structure 19. Therefore, the GaP system light emitting diode has obtained suffucuent higher luminance.

Title: Detection apparatus of effective stress of concrete
Inventor: NATSUME TADAHIKO
IPC: G01N33/38
Filed: 1993-10-28
Abstract: PURPOSE:To provide a high-precision stress detector by composing its case from a meshlike body of low elastic coefficient, and water-permeable isolating sheets which isolate concrete attached to both face of the body to isolate its inside from outside in terms of the stress of concrete. CONSTITUTION:Concrete which is filled into a case body 50 is isolated surely, in terms of a stress, from concrete, to be measured, around an apparatus by isolating sheets 52, 53. In addition, the concrete which is filled into the case body 50 can maintain the same state regarding individual points such as the material age, the water content state, the temperature and the stress state of the concrete, to be measured, around the apparatus due to the water permeability of the isolating sheets 52, 53 and of a core case 51. In addition, when the concrete is deformed, a deformation force acts on the case body 50. However, since the elastic coefficient of the core case 51 is extremely small, the existence of the core case 51 does not have a bad influence on the deformation force of the concrete, and the stress degree of only the concrete can be detected.
