Title: Image formation system of image fiber transmission line
Inventor: NISHIKAWA MITSURU
IPC: G02B6/06
Filed: 1982-03-30
Abstract: PURPOSE:To obtain an image fiber composite transmission line which facilitates the reduction and enlargement of a composite picture by providing one control lens behind the transmission-side element lens of the image fiber composite transmission line. CONSTITUTION:A bundle of image fibers 1 in use is provided successively from an image pickup side A to an image reception side B. At both ends of each image fiber 1, an image pickup side element lens 2 and a transmission side element lens 3 are arranged and when an object 4 to be photographed 4 is placed at the image pickup side A, luminous flux from the lens 3 converges to one point P (a, b) in an original picture 5'. For this purpose, when one control lens[focal length (f)]6 is placed behind the lenses 3, diffracted pieces of luminous flux are shown by equations 1 and 2 and converge to a new picture point S5 on a straight line OP. Further, the ratio of the distance from an origin is shown by an equation 3 and not influenced by the Y coordinate (b) of the point P. Therefore, a successive reduced or enlarged new picture 5 is obtained as a set of ponts S5.

Title: Scanner allowing scanning of various kinds of documents
Inventor: DOMINIKU BERUTORAN
IPC: H04N1/04
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To scan various kinds of documents, so as to adjust the inserting angle of documents to be scanned, while guaranteeing the parallelism of inserted documents without rubbing or damaging a surface in contact with that document. SOLUTION: While using a sensor line 12 provided with a light-emitting element, condenser element and light-receiving element, this scanner scans a document inserted along with a guide member 75 without contact. The inserted document is abutted to an abutting part 67 at a 1st mechanism 65 of a counter moving device 66 and made parallel with a scanning axis. When a sensor detects its parallelism to be normal, a relay 70 makes this scanner active, the abutting part 67 is pulled in, the document is contacted to a roller with pressure by a leaf spring 69 at a 2nd mechanism 68, and the document is sent by starting a motor for driving a roller 43. When scanning is finished, the relay 74 cancels the active state. Since the sensor line 12 is arranged coaxially with the roller 43 and can be oscillated around it, the document inserting angle can be adjusted.

Filed: 1998-02-15
Abstract: PROBLEM TO BE SOLVED: To effectively treat components in a plating waste soln. to recover nickel or phosphoric acid by treating the plating waste soln. with a chelating resin and subsequently oxidizing and decomposing hypophosphorous acid, phosphorous acid and an org. acid. SOLUTION: A packed column V is packed with a chelating resin and a plating waste soln. is injected into the column under pressure by a pump P-1 to be passed from below to above to be brought into contact with the chelating resin. Subsequently, silver plating is applied to the inner peripheral wall of an oxidizing treatment tank T-4 and surface roughening treatment is applied to the surface of the silver layer. By this method, the surface of the silver layer becomes silver peroxide by ozone used for oxidizing treatment and oxidation is further accelerated by the catalytic action of the silver peroxide. By this constitution, an org. acid is decomposed into water and carbon dioxide in the presence of the oxidizing agent by the irradiation with ultraviolet rays within the oxidizing treatment tank T-4 housing the waste soln. after the adsorptive removal of nickel while hypophosphorous acid and phosphorous acid become phosphoric acid by oxidation. The waste soln. after treatment is supplied to a reaction tank T-5 having a stirrer M to be reacted with a precipitant such as calcium hydroxide or the like under stirring and mixing.

Filed: 1990-03-01
Abstract: PURPOSE:To quickly find a fault to prevent disappearance of charging information by monitoring the number of speech charging information sent from an exchange to monitor the fault in speech charging information generating and transmitting parts. CONSTITUTION:When speech is started between users of a telephone network 1, speech charging information is generated in a PBX and is sent to a communication control part 5 of a charging system 4. The communication control part 5 writes information in a speech charging information storage file 6 and counts up a counter 13 of a corresponding PBX name 12 by one. All charging information are stored in the file 6 and are charged and calculated later with each user as the unit. The counter 13 of a speech frequency accumulation table 7 is cleared at 0 o'clock every day and is contend up. If speech charging information does not occur in PBXs 2a to 2n for a long time, the occurrence of trouble in PBX is forecasted, and a speech frequency monitor part 8 refers to the accumulation table 7; and when the increase of the frequency in a preliminarily set time is 0, a warning is displayed on a display device 9 and a buzzer 10 is sounded. By this constitution, disappearance of charging information due to delay of fault discovery is prevented.

IPC: H04B10/11
Filed: 1995-03-10
Abstract: PURPOSE: To miniaturize an optical communication device and to realize speedy and highly precise directional control by controlling the orientation of an optical antenna based on a directional error. CONSTITUTION: When coherent light is transmitted from a light transmission source, light is transmitted through a space and it arrives as transmission light. Light is received by the first to fourth antenna elements 10a-10d of the optical antenna 10 and it is guided to first to fourth phase converters 12a-12d. The phase converters 12a-12d phase-convert light signals inputted based on a phase control signal from a phase control part 14 and output them to a signal processing part 13. The signal processing part 13 generates a directional error signal based on first and second phase error signals and outputs them to a directional control part 11. The directional control part 11 direction-controls the optical antenna 10 to the light transmission source based on the directional error signal.  Thus, highly precise directional control can be realized without providing a sensor for error detection for detecting the directional error of the optical antenna 10.
