Title: Image processor
Inventor: FUKUSHIMA SHIGENOBU
IPC: G03G15/04
Filed: 1991-06-10
Abstract: PURPOSE:To reduce erroneous discrimination of edge intensifying components by intensifying edge only if there are a less number of picture elements in the periphery of restore processing object picture elements when restoring multivalued image from a pseudo halftone binary image data. CONSTITUTION:Pseudo halftone binary image data that is stored in matrix memory circuit 100 is restored to multivalued image data by a halftone data restoring section 101. Then, based on the concentration difference between a relevant picture element and its peripheral picture elements, an edge intensifying component calculating section 111 detects a corresponding amount of edge. Further, an edge discriminating section 113 discriminates a small number of picture elements in the binary image data contained in the first predetermined area including a relevant picture element, and also discriminates whether or not a small number of picture element are contained in the second predetermined area nested in the first predetermined area. Furthermore, when the above discrimination is denied, the edge quantity detected by the calculating section 111 is invalidated, and edge intensification is not executed. This constitution can reduce erroneous discrimination of edge intensification components.

Title: Signal processing method of focus detector
Inventor: MATSUMURA SUSUMU
IPC: G02B7/28
Filed: 1983-07-28
Abstract: PURPOSE:To improve the responsiveness of focus detection by performing calculation processing prior to the calculation of the extent of a shift in the relative position of an object image only when image contrast in one object image is larger than a specific value. CONSTITUTION:Luminous flux from the iris of a photographic lens 7 passes through a visual field aperture 9 for distance measurement, an image of the aperture 9 is formed again on a sensor surface 14 through a secondary image- forming lens 11 and then formed on sensor arrays 15 and 16 as two images by the luminous flux deflecting operation of an iris splitting means 12; and their outputs are supplied to a processor 21 for signal processing to detect the focus. When it is judged that the contrast is low, subsequent correlation calculation which requires a long time is omitted and the photographic lens 7 is moved to enter another image-formation state. Therefore, a low-contrast object is detected in the initial stage of signal processing, and the correlation calculation is started only when the contrast is sufficient to improve the responsiveness of the device, performing high-performance focus detection.

Title: Aural switch circuit
Inventor: ISHIZAKA TETSUO
IPC: H04B1/46
Filed: 1980-10-04
Abstract: PURPOSE:To prevent not only the malfunction due to the noise but the lowering of the talking quality due to the switching for an aural switch circuit that inserts and eliminates the loss, by having the comparison among the sending speed aural signal level, the receiving speed signal level and the noise level respectively. CONSTITUTION:The aural signal level of the sending speed input signal is compered with the noise level through the 1st comparator 8. Then the 1st inspecting  circuit 11 delivers continuously the netative voltage although the noise level is  temporarily higher than the aural level. Thus the under-talking state can be maintained. Furthermore at the receiver side, the receiving speech input signal is received  and compared with the sending speech input signal level. Then the sending speech  state is indicated in case when the negative potential is consecutively secured. The  negative potential is delivered for a certain period of time from the moment when  the result of comparison is changed to the intermediate potential from the negative potential. As a result, the state of transmission can be maintained for a certain period of time although the sending speed input signal is broken in a short time. The receiving speed state is quickly obtained when the result of comparison is set at the positive voltage.

IPC: D21C11/00
Filed: 1993-06-10
Abstract: PURPOSE: To provide a method for producing hydrogen peroxide for bleaching a cellulose pulp without direct electrolysis at a pulp plant. CONSTITUTION: A black liquor produced at a pulp plant is fed to a reactor 11 and heat-treated to separate sulfur in the form of an organosulfur compound- containing gas. The gas is fed to a hydro converter 14 and reacted with hydrogen to give a gas mixture containing methane, hydrogen sulfide and hydrogen, which is introduced into a white liquor scrubber 16 to separate hydrogen sulfide. The obtained sulfur-free methane gas is converted into hydrogen by a steam reforming converter 18 and the converted hydrogen is separated by a pressure shaking absorption purification apparatus 20. Hydrogen discharged from the apparatus 20 is divided into two flows, one flow is fed to a hydrogen peroxide production apparatus 23 to produce hydrogen peroxide and the other is supplied to the hydroconverter 14 and used for reducing the organosulfur compound. The produced hydrogen peroxide is fed to a stage P for bleaching a cellulose pulp in a pulp plant. Thus hydrogen peroxide is produced by an efficient method effective in terms of cost at a pulp plant and used for bleaching a cellulose pulp.
