This invention provides an image processing device capable of appropriately generating a synthetic image with an enlarged dynamic range even when a measuring article is moving. A work to be a reference (reference work) is imaged a plurality of times under an exposure condition same as that for generating a synthesized image, and specified regions are registered as reference images from a plurality of input images acquired in the respective imaging processes. In an operation mode, a plurality of input images is acquired by imaging a work a plurality of times under a plurality of exposure conditions, and search processes based on the reference images are executed on the respective input images. A partial image having a predetermined size is extracted from each of the plurality of input images based on each specified position, and an image synthesizing process is executed on the plurality of extracted partial images to generate a synthesized image.

A nanocarbon generation equipment designed such that organic processed materials can be quickly thermally decomposed therein and the decomposed materials are then quenched and liquefied to obtain liquefied materials is disclosed. This equipment comprises thermal reactor for quickly thermally decomposing the organic processed materials, apparatus for recovering the liquefied materials which are liquefied through quenching of thermally decomposed organic processed materials, a rotary furnace to be filled with a reducing atmosphere and loaded with hydrocarbons to be obtained through vaporization of liquefied materials after impurities contained in the liquefied materials are removed, and metal balls made of a metal selected from stainless steel, iron, nickel, chromium and an optional combination thereof, wherein the hydrocarbon introduced into the rotary furnace is decomposed into carbon and hydrogen, thus enabling nanocarbon to be produced through vapor-phase growth.
摘要:
An apparatus is provided with a component feeding member for feeding electronic components having lead wires in a tape-bonded state, an insertion head for separating the electronic components fed from the feeding member from the tapes and inserting to holes of a board, and a fixing head facing the insertion head via the board for cutting and folding the lead wires of the inserted electronic component in the board thereby fixing the electronic component to the board. AC servo motors operating independently of each other are individually set in the insertion head and the fixing head, which are controlled by a device so as to be synchronous with each other.
摘要:
A CPU provides a fluorescent light detecting head with an irradiation instruction, in response to which the fluorescent light detecting head irradiates an ultraviolet ray for detection on an ultraviolet curing resin material to be examined. The CPU then acquires from the fluorescent light detecting head an intensity of a fluorescent light emitted from a photo polymerization initiator included in the ultraviolet curing resin material when receiving the ultraviolet ray for detection. The CPU retrieves a predetermined number of past data of the intensity of the fluorescent light from a storage unit and performs a (moving) average calculation processing to calculate the intensity of the fluorescent light at the current time. The CPU performs an estimation processing of a state of the ultraviolet curing resin material based on the calculated intensity of the fluorescent light.

Two mirrors (15) and (16) making an angle of 90 degrees are formed on a front face of a mirror member (17). An optical fiber for input (12) and an optical fiber for output (13) are held in a fiber array (14) with a predetermined interval, and an emission lens (23) and an injection lens (24) are provided on a front face of the fiber array (14) in a way that they are opposed to end faces of the optical fiber for input (12) and the optical fiber for output (13) respectively. According to the variable optical attenuator, when the mirror member (17) is straightly moved by an actuator (18), light attenuation can be varied thereby.
摘要:
An optical reflection sensor emits light and its reflection from a target object is received. A signal processor carries out a measurement on the received reflected light such as the distance to the target object each time the reflected light is received. Repeatability of measured values is calculated and displayed on a display device incorporated into the housing of the sensor. The display device may have two display areas such that the calculated repeatability and the measured value can be displayed simultaneously. The calculated repeatability may be compared with a specified threshold value, with the result of the comparison displayed. The housing may also incorporate an input device through which a required level of accuracy may be set.
