A chip separation and alignment apparatus capable of accurately and readily accomplishing separation and alignment of chips with a simple construction. The apparatus includes a chip separation and alignment section and a chip separation section. The chip separation and alignment section includes a chip cassette formed into a flat rectangular box-like shape, in which are formed a chip storage chamber, a chip alignment hole provided with an upper end opening through which the chip alignment hole is communicated with a lower portion of the chip storage chamber and a lower end opening, and at least one air ejection port arranged near the upper end opening to intermittenly eject air therethrough. The chip separation section is arranged at the lower end opening of the chip alignment hole to separate chips one by one and to successively supply the separated chips to a subsequent step.

In this method for manufacturing an aluminum alloy, a porous preform is manufactured from a mixture of a finely divided oxide of a metallic element which has a weaker tendency to form oxide than does aluminum, and an additional substance substantially more finely divided than that metallic oxide. Then an aluminum alloy containing a substantial quantity of silicon is permeated in the molten state through the porous preform. This causes the metallic oxide to be reduced by a thermite reaction, to leave the metal which it included as alloyed with the aluminum alloy. At this time, the silicon in the aluminum alloy does not tend to crystallize out upon the particles of the metallic oxide, which would interfere with such a reduction reaction by forming crystalline silicon shells around such metallic oxide particles and would lead to a poor final product, because instead the silicon tends to crystallize out upon the particles of the additional substance. This alloying method is effective even if the average particle diameter of the finely divided metallic oxide, on the assumption that it is in the form of globular particles, is less than about 10 microns. The melting point of the additional substance should desirably be substantially higher than the melting point of the aluminum alloy. The silicon content of the aluminum alloy may freely be greater than about 1.65% by weight. Desirably, the preform may further contain reinforcing fibrous material. And, particularly, the additional substance may be Al.sub.2 O.sub.3.

Method and apparatus are provided for press-fitting caps on electric parts and the like. The apparatus has a device for feeding component rods of electric parts to a rod-conveying wheel provided on its circumference with lateral equally spaced grooves for receiving the rods fed from the rod-feeding device one by one, and a cap-feeding device for feeding caps to a pair of cap-conveying wheels each provided on its circumference with lateral equally-spaced grooves for receiving the caps fed from the cap-feeding device, the cap-conveying wheels being arranged symmetrically and obliquely with respect to the rod-conveying wheel so that the lower ends thereof come in contact with the lower end of the rod-conveying wheel thereby to press-fit the caps on the rods successively, and the rod-conveying and cap-conveying wheels being rotated in synchronization with one another. The method performed using the above apparatus comprises: feeding the rods onto the lateral grooves of the rod-conveying wheel one by one, feeding the caps onto the lateral grooves of the cap-conveying wheels one by one, and press-fitting the caps on both ends of the respective rods in succession.

Provided is a mounting structure capable of maintaining highly accurate connection reliability even when the temperature of the environment in which the mounting structure is used is high. Mounting structure (10) includes electronic component (11), metal (12), wiring substrate (13), and a preventing structure. Electronic component (11) includes first electrode (14). The melting point of metal (12) is 130° C. or less. Wiring substrate (13) includes second electrode (15) electrically connected to first electrode (14) via metal (12). The preventing structure prevents flowing-out of metal (12) in a melted state from a region where first electrode (14) and second electrode (15) are formed. Further, preventing structure (14) is formed in at least one member selected from electronic component (11) and wiring substrate (12).
摘要:
An imaging mode is automatically switched based on the kind of a subject. The spatial frequency of an endoscopic image obtained by imaging the subject is detected. Further, judgment is made, based on the distribution of the spatial frequency, as to whether the endoscopic image was obtained by performing close-up imaging on the subject. The condition of imaging is switched based on the result of judgment as to whether the image was obtained by close-up imaging or distant-view imaging.
摘要:
The method and the apparatus for correcting images extract one or more features including information about face region for each of photographed images, classify the photographed images into groups of particular photographed images having at least one common feature in accordance with at least one of the extracted one or more features, calculate, for the particular photographed images that have been classified in one group, a common correction amount for adjusting the face region to have an appropriate color density in accordance with the extracted one or more features and a type of the one group and correct the particular photographed images belonging to the one group by the calculated common correction amount.
摘要:
A person image correcting apparatus and a person image correcting method that reproduce face colors of persons in an image group consisting of a plurality of images shot under identical shooting conditions, with an appropriate color and/or density, prevent variations in the background colors, and effectively perform correcting process, even if the image group contains an image of a person having a significantly different face color from other persons, are proposed. Two or more display images that are different in face color are selected from the plurality of person images, based on a feature amount in a face region, and displayed. When a modification value of color or density is inputted, all of the display images are corrected using the inputted modification value, and the corrected images are redisplayed. When an instruction for confirming the modification value is inputted, all of the plurality of person images are corrected and outputted.
摘要:
When a wavelength set for a spectral estimation image is set through an input means, ON/OFF of light emitting devices is controlled based on the set wavelength set. Further, an endoscopic image of a subject illuminated with light of a predetermined wavelength band or bands is obtained by a scope. Matrix operation is performed on the endoscopic image to generate the spectral estimation image.
