摘要:
An apparatus for tracing and recording image lines includes a coordinate reader which detects coordinate values of an image to be traced; an image sensor which is movable in a plane relative to a table; a memory in which image signals detected by means of the sensor are written; and a central processing unit which controls the above elements of the apparatus. Trace data are obtained by means of the coordinate reader which detects coordinate values of the image lines. Then, the image is positioned on the table, where record data are obtained based on the trace data by means of the image sensor which generates image signals corresponding exactly to the image.
摘要:
A method for tracing an object such as an outline of a picture or a line image, wherein the object is sensed by a set of sensing elements arranged in an optical head moving along the object, to detect a position and a direction of the object, wherein the optical head is controlled to trace the object depending on the detected position and the direction of the object, and wherein the object is reproduced by reproduction means which is moved in synchronization with the optical head. Present invention improves this method by moving the optical head along portions of the object, which the sensing elements can discriminate hardly or not at all nor follow the object, according to line segment data which is predetermined and represent a plurality of points of coordinates.

A method for producing a halftone plate from an original picture having a continuous tone. A record film is exposed at least one exposure light beam of a smaller size than a halftone dot area by independently controlling it to turn on or off according to a picture signal. The luminous energy of the exposure light beam is controlled depending on a reference value corresponding to the picture signal and a position signal value varied depending on an exposing position in the halftone dot area to be exposed by the exposure light beam. The control of the luminous energy is performed by the sum, the difference, the product or the quotient of the two signal values. A plurality of reference values or position signal values may be used.

A method and machine for positioning films on base sheets are disclosed. A first film on a base sheet is laid out into a desired position on a base plate, and positions of edges of a picture pattern on the first film are detected by photoelectric detectors including photoelectric elements which detect the edges and output signals whose strengths are varied depending on the positions of the elements with respect to the edges. Then, a second film on a base sheet is put on the first film so that edges of a picture pattern of the same shape as in the first film, on the second film may approximately overlap to those of the first film, and the edges in the second film are completely coincided with those in the first film by moving the second film by means of a drive means according to the output signals from the elements, thereby positioning the second film into the desired position.

A method and machine for positioning films on base sheets is disclosed. A first film on a base sheet is laid out into a desired position on a base plate, and positions of register marks attached on the first film are detected by photoelectric detectors including photoelectric elements which detect the register marks and output signals whose strengths are varied depending on the positions of the elements with respect to the register marks. Then, a second film on a base sheet is put on the first film so that the register marks on the second film, which are marked in the same positions as those of the first film, may approximately overlap those register marks of the first film, and the register marks of the second film become coincident with those of the first film by moving the second film by means of a drive means according to the output signals from the photoelectric elements, thereby positioning the second film into the desired position.

A wavelength swept light source includes a sawtooth waveform as a main waveform and an exponential component of the sawtooth waveform to the controlled voltage of the electro-optic deflector. The controlled voltage is controlled so that, as an oscillation wavelength to be swept is swept towards a longer wavelength side, a change rate of the oscillation wavelength is increased.

An image forming apparatus includes an image carrier that carries an electrostatic latent image; a developer supplying unit that supplies developer by being driven at a predetermined speed; a developing unit that develops the electrostatic latent image, while a transporting member transports the developer, a transport speed of the transporting member being switched to a plurality of speeds; a determining unit that determines whether or not an operation where a supply capacity of the developer supplying unit is greater than a transport capacity of the developing unit exceeds a predetermined threshold value and is continued; and a controller that performs control so that, when the determining unit determines that the operation exceeds the predetermined threshold value and is continued, an operation that was being executed immediately prior to the determination is stopped to forcefully drive the transporting member of the developing unit for a predetermined driving time.
摘要:
Provided is a method for rapidly and easily detecting a mutated nucleic acid, which is contained in a small amount in a nucleic acid sample together with wild-type nucleic acids, with high specificity and high sensitivity. In the method of the present invention, amplification of a detection region comprising a target site by a nucleic acid amplification method is inhibited, by the steps of allowing a nucleic acid having a target site to coexist with a clamp probe comprising a photo-crosslinking nucleic acid and having a sequence complementary to the target site, and photo-crosslinking the nucleic acid having the target site with the clamp probe by photo-irradiation.
摘要:
A developer container is provided with a container body. An opening is formed through the container body. An opening/closing lid closes the opening. A lid holding frame holds the opening/closing lid in such a manner that the opening/closing lid can move between an open position and a closed position. A stopper stops the opening/closing lid and thereby preventing it from moving toward the open position in a state that the opening/closing lid is located at the closed position. A contact portion comes into contact with a hook portion provided in a container receiving portion when the developer container is inserted into the container receiving portion. A deformable portion deforms the stopper to such an extent that the stopping of the opening/closing lid by the stopper is canceled when the developer container is inserted into the container receiving portion and the contact portion comes into contact with the hook portion.

A member for agitating and conveying a developer, includes: a rotation shaft that rotates in a given direction; a spiral-shaped conveying member that is disposed on an outer circumferential surface of the rotation shaft; and conveys a developer in a shaft direction of the rotation shaft; a protruded agitation section that protrudes, with a gap from the rotation shaft, from the spiral-shaped conveying member toward an upstream side in a developer conveying direction; and agitates the developer; and a diameter directional conveying section that is disposed between adjacent spires of the spiral-shaped conveying member; is disposed in a downstream side in the developer conveying direction with respect to the protruded agitation section; and gives a diameter directional conveying force to the developer.
