Title: Image reader
Inventor: KOBAYASHI TOSHIYUKI
IPC: H04N1/409
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an image reader without causing 'fogged focus' or 'black pixels resulting from deformed pixels', even if there is lifted part such as the binding margin of a thick book in the original reader adopting a contact image scanner(CIS) system. SOLUTION: When a spread book original placed on an original platen is read, when a white background read output value within a prescribed range is decreasing during scanning of the original side, it is discriminated that a file margin of the original has been scanned, then a read storage time is extended, a mobile speed of a running body is decreased, and an edge enhancement processing (MTF) correction coefficient is reinforced. Furthermore, when the output of a white background read output within a prescribed range is increasing, it is discriminated that the outside of the file margin of the original is scanned, the read storage time and the mobile speed of the running body are restored, and the MTF correction coefficient is restored to the original weak coefficient by means of a control means 12a.

Title: Detecting method of chromaticity of lumber surface
Inventor: IKARI MOTOO
IPC: G01J4/00
Filed: 1979-02-13
Abstract: PURPOSE:To eliminate an error due to surface reflected light and raise the reliability of examination of chromaticity of lumber surface, by placing polarizers for a light projector and a light receiver and inclining the polarization of the polarizers rectangularly to each other centering the proceeding directions of light. CONSTITUTION:Sliced veneer 6, whose chromaticity is to be examined, is moved in the direction of an arrow by a conveyor 7. Laser light is irradiated from a laser beam projector 8 upon the veneer through a polarizing filter 9 and a rotary mirror 10 to scan the surface of the veneer 6. The light reflected from the veneer is transmitted to a light receiver 11 through another polarizing filter 12. At that time, the polarization planes of the polarizing filters 9, 12 are inclined rectangularly to each other centering the proceeding directions of the light. As a result, the light regularly reflected on the surface of the lumber does not pass through the polarizing filters because the light is hardly polarized. Only scattered light polarized by the surface of the lumber passes through polarizing filter on the side of the light receiver. This results in providing a lumber surface chromaticity examination unit which is not affected by luster.

Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To suppress the decrease in viscosity for a long period of time at room temperature or under heat by adding acetic acid and thiourea to a water- soluble polymer composition. SOLUTION: To a water-soluble polymer composition, desirably an aqueous solution of an acrylamide-based water-soluble polymer, are added desirably 0.1-1 pt.wt., 0.1-0.3 pt.wt. in particular, based on 100 pts.wt. of the water soluble polymer, of acetic acid and desirably 0.05-5 pts.wt., 0.2-1 pt.wt. in particular, based on 100 pts.wt. of the water soluble polymer, of thiourea. Thus, the water- soluble polymer is prevented from decomposition with time and the aqueous solution thereof does not suffer from decrease in viscosity for a long period of time to be kept stable. Therefore, it is used suitably, for example, for the preparation of black matrices of a cathode ray tube. The water-soluble polymer is desirably dissolved in a concentration of 3-15 wt.% in an aqueous solution.  As the water-soluble polymers are exemplified an acrylamide-diacetone acrylamide copolymer, a polyacrylamide and the like.

Title: Cooling system for marine engine
Inventor: MIZUSHIMA KATSUMI
IPC: F01P3/20
Filed: 1979-02-14
Abstract: PURPOSE: To prevent the accumulation of air in an outflow chamber at a heat exchanger, and to improve cooling performance, by a mechanism wherein a communicating passage is mounted which mutually communicates the outflow chamber and an upper portion of an inflow chamber.  
     CONSTITUTION: Cooling water for an engine flows into an inflow chamber 7 from an inflow port 10, bubbles are separated here, the bubbles separated open a valve body when the pressure becomes not less than fixed pressure and are exhausted, the cooling water, from which the bubbles are separated, passes through a heat exchanging element 12, is cooled and is forwarded to an outflow chamber 8, the bubbles remaining in the cooling water are perfectly separated here, the cooling water is transmitted to an engine from an outflow port 11. Since the inflow chamber 7 and the outflow chamber 8 are communicated by a communicating hole 30 at an upper portion at that time, air in the outflow chamber 8 is exhausted through the inflow chamber 7. Thus, air does not accumulate in the outflow chamber 8 in a large quantity, the cooling action of the cooling water is not obstructed, and cooling performance is improved.

Abstract: PURPOSE:To prevent damage on circuit elements with avoidance of overcurrent flowing into a capacitor upon power recovery from an instantaneous interruption of an AC power source by setting a bypass means of a charging current limiting resistor set to the operation mode forcedly to the nonoperation mode. CONSTITUTION:When a power source switch 18 is turned on, a capacitor 22 starts to be charged, and a capacitor 13 starts to be charged via a resistor 12. When the capacitor 22 is charged up to a predetermined voltage, a light emitting element of a photocoupler emits light to turn its photoreceptor 27 into a continuity.

Filed: 1985-01-30
Abstract: PURPOSE:To reduce to half the conventional number of memory chips of a small-scale microprocessor system by allocating two different logical memory spaces formed at the highest-order and lowest-order parts of a logical memory into the same physical space. CONSTITUTION:A microprocessor exclusive area 20 formed at the lowest part of a logical memory and a user program area 21 are allocated as they are to a physical memory as areas 20A and 21A respectively. Here a microprocessor exclusive area 22A at the highest part of the logical memory is allocated at an area equal to a hitherto unused area 23. Thus both the highest and lowest areas 22A and 20A are allocated to a single ROM. In such a way, the conventional number of conventional memory chips of a small-scale microprocessor can be reduced to half by allocating the highest and lowest logical memory spaces to the same physical memory.

Abstract: PURPOSE:To hold time transparency by taking a difference between a packet (n) and a packet n+k+1 so as to insert a pseudo packet by k+1 packets with respect to packets n+1-n+k aborted in the network. CONSTITUTION:Let a sequence number added to a packet be a series taking 256 as modulus, then N=5 is set. When a sequence number of a packet 30 reaching a receiver 601 is in the range of (X+N+1)-X with respect to the sequence number X of the packet being reproduced by a packet decomposing device 609, a delay detector 602 aborts the arrived packet and when a sequence number of a packet 30 reaching the receiver 601 is in the range of (X+1)-(X+N), the delay detector 602 sends the packet to an inter-sequence difference calculator 603. Then the inter-sequence difference calculator 603 calculates the difference of the sequence number of the packet arrived in the receiver 601 and the sequence number processed just before. A comparator 604 releases a gate F 605 when the difference is 2 or over and a pseudo packet generator 606 sends the generated pseudo packet to a packet buffer 607.

IPC: H04B10/60
Filed: 1991-01-14
Abstract: PURPOSE:To provide the optical exclusive OR circuit which can make an exclusive OR operation between two light input signals. CONSTITUTION:Two light beams propagating in space or in waveguides or in optical fibers are formed as 1st to 4th light beams and are guided to a 1st optical inverter element 101a and a 2nd optical inverter element 101b. The 1st and 2nd inverter elements are inputted with these 1st to 4th light beams and output these beams by lowering the light transmittance or light reflectivity thereof. The output light beams are multiplexed by an optical output section 112 and are outputted. Consequently, the exclusive OR operation of the two light signals is eventually executed by effectively utilizing the wide band characteristics of the optical elements and since the circuits are constituted of only the elements having the inverter functions, the computation of the exclusive OR by one stage of operation is executed and the need for obtaining synchronization between the elements is eliminated. In addition, the circuitry is simplified and the integration of the circuits is facilitated.
