Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a printed matter discriminating device for discriminating and outputting an index for optimally judging a printed matter regardless of a color printed matter and a black-and-white one. SOLUTION: An image formed on a printed matter to be judged is converted into an RGB electrical signal by a photoelectric conversion element 2 of an image-reading part 1 and is converted into a digital signal by an A/D conversion part 3. RGB image information is converted into image information (signal DATA) for each coloring agent by a color conversion part 5 of a detection part 4, thus counting the amount of coloring agent by a part 6 for counting the number of pixels. A count value for each coloring agent at the part 6 for counting the number of pixels is inputted to a discrimination part 7 for discriminating the index for judging a printed matter and outputting a discrimination result.  Since the amount of coloring agent is detected for each coloring agent and an index for judgment is discriminated, the amount of coloring agent can be detected accurately even in the case of a color image where the coloring agent is overlapped for accurate judgment.

Title: Diffraction grating pattern
Inventor: TAKAHASHI SUSUMU
IPC: G02B5/18
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To have satisfactory optical function and environmental resistance and obtain a decorative effect and a security effect by forming a portion of a diffraction grating pattern to have an asymmetrical section. SOLUTION: Two kinds of blazed gratings A, B are used and two gratings have the same shape and are different in a direction by 180 deg. and these two kinds of gratings are combined and arranged on the surface of a board to express a pattern (letter 'T'). When the diffraction grating pattern is irradiated from above and below by illuminating light, an observer can observe a negative- positive reversed different pattern (The letter 'T' is brilliant or its reverse). Thus, the diffraction grating pattern has anisotropy in the direction of emitting diffracted light according to the grating shape and direction, so that various expression can be made. Accordingly, even with the same display pattern, the patterns can be differentiated so as to contribute to giving security.

Title: Dual-conductor spiral antenna
Inventor: AKAHA NORIYUKI
IPC: H01Q9/27
Filed: 1982-01-19
Abstract: PURPOSE:To improve the axis-ratio characteristic of a circular polarized wave radiated at a low frequency in an operation frequency band by using two different-length conductors and arranging their outer circumferential terminal parts at asymmetrical positions about the center. CONSTITUTION:An electromagnetic wave radiated from an antenna has a circular polarized wave component radiated while propagating in current band area and a linear polarized wave component radiated by a current in a standing wave state. A spiral conductor 2' is shorter than a spiral conductor 1 and positioned asymmetrically about a center 7 as compared with an outer circumferential terminal part 5. Waves 10, 11, and 12 corresponding to a non-node part of the standing wave are asymmetrical with waves 10'', 11'', and 12'' about the center 7. Therefore, radiated waves by the conductors 1 and 2' have planes of polarization as shown by arrows 20 and 20'' and are linear polarized wave components different in time and space from each other. When those linear polarized wave components are put together, the standing wave on the conductors decreases in amplitude and an electromagnetic field having the same rotational direction with the circular polarized wave is produced.

Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To detect the same channel interference by providing a BPF when directly receives the phase of a Q-channel output signal of a synchronous demodulator and comparing the averaged signals passing through the BPF with the threshold. SOLUTION: A synchronous demodulator 14 connected to an IF stage of a receiver that receivers the stereo signals of an AM frequency band outputs a Q-channel single signal. Receiving this signal, a BPF filter 22 transmits the signals having the frequency of about 25Hz, for example. An integrator 24 averages the signals passing through the BPF 22. A high comparactor 28 compares the averaged signals with the high threshold 32 (higher than a desired phase modulation level by 50%). A low comparator 30 compares the averaged signals with the low threshold 34 (lower than a desired phase modulation level by 50%). An AND of outputs of both comparators 28 and 30 shows the presence of the same channel interference. Under such conditions, a stereo mode is canceled.
