IPC: H04B1/62
Filed: 1981-03-10
Abstract: PURPOSE:To inprove a noise modulation phenomenon effectively by weighting the high frequency side and low frequency side of control voltages for a compressor and an expander corresponding to their emphasis characterisitcs, and synthesizing the results by addition. CONSTITUTION:In a compressor D, an input signal is passed through a preemphasizing circuit 22 and a variable gain control circuit 23 to send a level-compressed signal to a recording medium E. The output signal of the circuit 23 is separated through an LPF24 and an HPF25 into a low-frequency and a high-frequency component, which are weighted corresponding to pre-emphasis characteristics by control gain setting circuits 30 and 31 after passing through rectifying circuits and integral time constant circuits, thereby outputting low-frequency and high-frequency control voltages ECL and ECH. Then, the circuit 23 is controlled by a control signal E0 obtained by adding said voltages at a part 32. In an expander F, a signal from the medium E is received by a variable gain control circuit 35, an LPF37, and an HPF38. The outputs of the LPF and HPF are passed through rectifying circuits, integral time constant circuits, and control gain setting circuits 30 and 31 to output control voltages ECL and ECH, and the circuit 35 is controlled by a signal E0 obtained by adding said voltages at a part 45 to expand the level, thereby de-emphasizing and outputting the output of the circuit 35 through a part 36.

Title: Azimuthal polarimeter
Inventor: MINAMI TAKAAKI
IPC: G01J4/04
Filed: 1993-01-30
Abstract: PURPOSE:To obtain a large optical rotation angle signal so as to improve the S/N of the detector by providing reflecting surfaces perpendicular to each other on the polarized light transmitting side of a sample cell so that polarized light can again pass through the sample cell. CONSTITUTION:The light emitted from a light source 1 is linearly polarized through a polarizer 3 and the polarized light reaches a reflecting body 15 after passing through a Farady cell 5 and sample cell 14. The polarized light is reflected by the reflecting body 15 by 180 deg. and reaches a detector 8 after passing through the cell 14 and an analyzer 7. In other words, the light from the light source 1 passes through the cell 14 twice. While the light is turned by a plane of polarization theta whenever the light passes through the sample, the polarize light is reflected by plane mirrors 16 and 17 which are arranged perpendicularly to each other and constitute the reflecting body 15 and the rotational angle of the polarized light is added twice, and then, only the light the plane of polarization of which is turned by 2 is made incident to the detector 8. The optical rotation angle of the sample becomes theta which is obtained by dividing 26 by the number of passing times which is 2. In this case, the length of the optical path of the cell 14 is multiplied by the number of passing times. When such a constitution is used, the S/N can be improved, because the optical rotation angle can be increased as a signal.

Title: Supervisory system of digital repeater
Inventor: SAKAMOTO HIROSHI
IPC: H04B17/40
Filed: 1984-02-28
Abstract: PURPOSE:To discriminate a repeater performing abnormal operation from the result of arithmetic operation by adding a multiplier having a specific function to each repeater. CONSTITUTION:The multiplier having specific functions g1(x)-gn(x) is added to the repeaters 1-n between a transmission section 10 and a reception section 20. Each repeater multiplies a code of the signal transmitted from the transmission section 10 by the specific function. On the other hand, the reception section 20 divides sequentially the received code by using the specific functions respectively. When the repeaters 1-n are operated normally, no remainder term is caused, and if any repeater is faulty, the remainder term is produced. Thus, a repeater causing a fault is identified by detecting the remainder term. Thus, the repeater of faulty operation is discriminated from the result of arithmetic operation.

IPC: G01N21/892
Filed: 1984-02-28
Abstract: PURPOSE:To improve the detection precision by resolving effectively bad influences due to oxide scal in case of detection of surface defects in an optical active method. CONSTITUTION:Though a material to be examined which is descaled by a device 1 is sent to a succeeding flaw detection stage, oxide scale is immediately generated on the material to be examined because of a high temperature. An LPF is used to reduce noise components for the purpose of eliminating influences of ruggedness which is generated by shot blasting. Consequently, it is necessary that a part to be detected is observed immediately after descaling, and therefore, a flaw detecting camera 2 is installed as close to the descaling device 1 as possible.

Title: Weft detecting apparatus for weaving machine
Inventor: YAMADA SHIGEO
IPC: D03D51/34
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To shorten the length of trimmed selvedge of weft without making the detection of weft unstable. SOLUTION: This reflection type weft detecting apparatus 10 in a weaving machine comprises a light projector 16 for emitting light heading toward a flying route of weft and light sensors 18 and 20 which are laid side by side with the light projector 16 in the weft inserting direction and are equipped with light receiving lenses 42 and 52 for receiving reflected light among light rays. The light receiving lenses 42 and 52 have a dimension of a light incident part in the weft inserting direction smaller than a dimension at a part opposite to the light incident part in which at least a part of the difference in dimension is made by the light projector 16 of the light receiving lenses 42 and 52 and by an end part at the opposite side of the light projector.  Consequently, even if a distance between the light sensors 18 and 20 and an adjoining yarn is shortened, the yarn adjoining the light sensors 18 and 20 is out of a detecting zone of the light sensors 18 and 20, reflected light from the yarn adjoining to the light sensors 18 and 20 will not be injected to the light sensors 18 and 20. Consequently, the light sensors 18 and 20 have no fear of causing reduction in light receiving level.
