Title: Current sensor
Inventor: SASAKI MASAYUKI
IPC: G01R15/20
Filed: 1992-03-06
Abstract: PURPOSE:To reduce measurement error due to eddy current which is generated in a metal chassis when measuring current in a noncontact type current sensor where a core, etc., which is made of a magnetic material is housed in the metal chassis. CONSTITUTION:Accessories such as a core 3 which is made of a magnetic material and a sensor 4 which detects a magnetic field are provided within metal chasses 1 and 2. When current to be measured flows through a cable which is mounted to a through hole which is provided at the center of the metal chasses. an output corresponding to the current to be measured is generated by the sensor 4. When current to be measured flows, an eddy current is generated in the metal chasses 1 and 2. However, since an insulation member 6 is provided at the metal chasses 1 and 2, a closed circuit where the eddy current flows is cut off, thus reducing measurement error due to the eddy current.

Title: Optical fiber bundle for image transmission
Inventor: GOTOU JIYUNJIROU
IPC: G02B6/04
Filed: 1980-04-15
Abstract: PURPOSE:To eliminate the occurrence of optical defects such as distortion, blur and the like of optical fibers in the peripheral part of the end face of an optical fiber bundle for image transmission by forming the peripheral part of said fiber bundle of light absorptive fibers. CONSTITUTION:Strip-shaped fiber aggregate 22 is formed by using optical fibers 12 such as multicore optical fibers. This aggregate 22 is put in dies, by which it is pressurized, compressed and secured, to make an integral optical fiber bundle. At this time, the optical fibers 31 in the area of the peripheral part of the optical fiber bundle is formed of the light absorptive fibers formed by adding a small amount of ferric oxide or the like. Since this area of the light absorptive fibers is not used for image transmission, the problem of the degradation in the quality of image transmission on account of the deformation, disordered configuration, etc. of the optical fibers in the image transmission area is eliminated. Undesired light is absorbed in the light absorptive fiber area, and therefore the sharp light image free from distortions is transmitted and is taken out.

Title: Production of metal powder
Inventor: HAYASHI AKINARI
IPC: B22F9/30
Filed: 1979-04-23
Abstract: PURPOSE: To produce the metal powder which does not cause sintering and is nevertheless good in reaction efficiency and has less danger of ignition by dispersing metal compound powder such as of iron oxalate into silicone oil, blowing H 2  and reduction-treating the same under heating.  
     CONSTITUTION: Metal oxide composed primarily of Fe (oxyhydroxide) and metal compound powder such as of oxalate of Fe, Ni or Co is dispersed into silicone oil. Thence, this dispersion is heated and reduction-treated under H 2  blowing. This yields the ferromagnetic metal powder used for magnetic recording media such as magnetic tapes. This method inhibits the sintering of the particles because the silicone oil interposes among the particles and further it improves the contact between H 2  and particle surfaces because the reduced by-products of the particle surfaces are discharged to outside the system from the liquid phase owing to stirring of the silicone oil, thus the H 2  consumption can be small.

Title: Paper supply device
Inventor: KOMADA SATOSHI
IPC: B65H3/52
Filed: 1984-03-14
Abstract: PURPOSE:To make it possible to surely prevent two overlapping sheets from being fed, by providing such an arrangement that a normally rotating roller is rotated in the paper feed direction under operation of a one-way clutch even upon a drive source for the roller being rested. CONSTITUTION:When the leading end of a paper 3 reaches a feed roller 8, a sensor 14 detects this leading end so that a step motor 9 for driving a normlly rotating roller 1 is rested in association with the output of the sensor 14. The paper 3 is continuously fed by the feed roller 8, and at this time, since a one way-clutch is applied with torque in its sliding direction, the normally rotating roller 1 may be rotated in association with the advance of the paper 3 even if the step motor 9 is rested. When the paper 3 has completely passed through the pressing section between the normally rotating roller 1 and a reverse roller 2, the normally rotating roller stops its rotation, thereby papers subsequent to the second one may be sustained in a stand-by condition.

Abstract: PURPOSE:To provide an excellent small-loss characteristic and to perform optical switching independent upon wavelength by forming a waveguide layer as a low carrier layer interposed between a semiconductor substrate having a high carrier concentration and a clad layer and surrounding the waveguide layer with the upper clad layer on both sides. CONSTITUTION:A waveguide layer 6 is vertically interposed between a lower clad layer 4 of first conductive type and an upper clad layer 8 of second conductive type, which have an inhibition zone larger than that of the layer 6, to have a double hetero structure. A low-refractive index area is generated in a part of the waveguide layer 6 by the plasma effect, and incident light is totally reflected on the boundary independently of the wavelength. The waveguide layer 6 is the low carrier layer interposed between upper and lower clad layers 8 and 4 and is surrounded with the upper clad layer on both sides, and the carrier injection area is limited by a low resistance area 14 and an electric current block area 4a to reduce the loss, thereby performing the optical switching of high extinction ratio. Thus, a semiconductor optical switch is obtained which has the small-loss characteristic improved and is independent of the wavelength.

Abstract: PURPOSE:To prevent the bend and breakage of an external blade in a boundary by supporting the boundary between the main area and a side peripheral area by means of the internal side surfaces of an external blade fitting plate and an external blade base. CONSTITUTION:Between the main area 17a of an external blade 17, in which numerous holes of a size for whiskers to pass, and side peripheral areas 17b to be thin located at both sides of the main area 17a, a boundary A in a stage condition to be weak from the viewpoint of a strength is formed. At such a time, a fitting plate 18 for fitting the external blade 17 to an external blade base 16 is made to overlap the boundary A, the plate 18 is mounted to both side peripheral parts of the external blade 17, simultaneously, the boundary A is made to overlap the internal side surface of the external blade base 16, and the external blade 17 is fitted to the external blade base 16. As a result, the boundary A is supported by the internal side surfaces of the fitting plate 18 and external blade base 16. Thus, even when the external blade 17 receives an external force from a side surface side at the time of shaving, the boundary A of the external blade 17 cannot be pressed against an opening periphery 16b of the external blade base 16. For such a reason, the bend and breakage of the external blade 17 in the boundary A can be prevented.
