Title: Method and apparatus for testing optical fiber by introduction of bending at multiple simulated peeling positions
Inventor: BINSENTO ERU JIYOONZU
IPC: G01M11/08
Filed: 1991-03-28
Abstract: PURPOSE: To provide a test method wherein a curvature state is simulated for test of curvature loss of an optical fiber and output of a test signal is enlarged. CONSTITUTION: A wound optical fiber 28 is wound around a curvature mandrel 10, a plurality of simulated peeling point curvature positions are formed at each winding corner, and light is transmitted from a light source through the optical fiber to detect it with a detector 34. It is compared with original intensity by a comparator 38, and attenuation of a small attenuation quantity and difficult to be measured at one point is detected as the total of a plurality of peeling point curvatures by measuring its attenuation. A few peeling point curvatures can be obtained by one winding, furthermore if the number of winding is increased, a large attenuation quantity can be obtained for increasing the number of the curvatures.

Abstract: PURPOSE:To form a recess into a resonance damping chamber as well as to improve an abating effect of forced air noise by forming the recess in a substrate of an inside-outside air transfer damper, and installing the cover formed with a hole which interconnects the inside and outside of the recess so as to cover this recess. CONSTITUTION:Each of inside-outside air inlet ports 1a and 1a opened to an inside-outside transfer box 1 is selectively opened or closed by an inside-outside transfer damper 3 supported by a shaft 3 free of rotation. In this case, a substrate 4 is installed in this damper after being clamped to the shaft 3, while a recess 5 is formed in this substrate 4 so as to be projected toward an outside air inlet port 1b. In addition, in this substrate 4, a cover 6 is fixed to a surface to be opposed to the inside air inlet port 1a so as to block up an opening of the recess 5, while a noise absorbing member 7 is attached to an outer surface of the cover 6. Furthermore, a circular hole 8, interconnecting the inside and outside of the recess 5, is opened to the cover 6 and the noise absorbing member 7 each. With this constitution, the recess 5 is formed into a resonance damping chamber, thus forced air noise is abated.

Title: Projector
Inventor: KASHIWAGI KAZUO
IPC: G03B27/34
Filed: 1983-05-23
Abstract: PURPOSE:To obtain an image with a proper illuminance distribution on a projection surface by controling a member which measures the distribution of the quantity of light passed through a projection lens and varies the illuminance distribution on the projection surface on the basis of the measured value. CONSTITUTION:A filter 100 consists of a circular density filter which has the smallest light transmissivity at the center part and increases in light transmissivity gradually from the center part to the circumferential part. When a motor 218 is rotated through a motor driving circuit with a start signal, the filter 100 starts rotating as shown by an arrow M. A detection signal is outputted when difference in output between the 1st photoelectric converting element 200 and the 2nd photoelectric converting element 201 arranged behind a half-mirror 108 is minimized, and the motor 218 is stopped through the motor driving circuit with the signal. Consequently, the unevenness of the illuminance distribution on the projection surface is corrected to adjust a light system correctly.

Title: Portable radio unit antenna
Inventor: MURAKAMI OSAMU
IPC: H01Q1/24
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a portable radio unit antenna which can reduce its size and weight and has high performance to stand its drop impact by using a composite material consisting of a high polymer material and an inorganic filler to an antenna core and an antenna coating material and at least to the antenna core. SOLUTION: An antenna core 2 and an antenna coating material 4 use a composite material consisting of a high polymer material and an inorganic filler. The composite material has a high relevant dielectric constant and a low dielectric loss in comparison with a high polymer material itself to reduce the size and weight of an antenna. The same effect is secured even when the composite material is used to only the core 2. When a soft composite material is used as the material 4, the anti-impact strength of the antenna is improved even when it is dropped while a portable radio unit is used. Furthermore, the core 2 is unified with its support part 5 so that the total size of the antenna can be reduced.

Title: Method and device for elimination of inter-code interference by decision feedback
Inventor: KANEMASA AKIRA
IPC: H04L25/03
Filed: 1986-04-18
Abstract: PURPOSE:To eliminate the interference caused within a symbol waveform by using a one-tap adaptive filter. CONSTITUTION:It is possible to extract only the residual inter-code interference component with a certain positive probability excluding zero by obtaining the sum of or difference between the present sample value and that preceding by MT seconds (M: an integer, T:a data period) in terms of a differential signal ( received signal containing the residual inter-code interference component). Therefore said sum or difference is used as an error signal to up date the coefficient only when said interference component is correctly extracted. Thus the adaptive working of an adaptive filter 25 is secured. While the artificial inter-code interference signal, i.e., the output of an adaptive filter 20 is supplied to an adder 22 and added with the output of the filter 25 to be fed to a subtractor 2. Then the inter-code interference produced at the zero-cross point of the same symbol waveform end is eliminated by the waveform in a symbol.
