摘要:
An apparatus for mounting a wire component on a substrate has a feed device for feeding a wire a predetermined length intermittently, and an insert device for cutting the wire fed out by the feed device, bending the cut wire to form a wire component, rotating and positioning the wire component, and then inserting the wire component in a hole defined in the substrate. In particular, irrespective of a position of the insert device, the feed device feeds out the wire in a direction where no interference would occur between the feed device and the insert device.

This invention relates to an electronic component mounting apparatus. In the apparatus, a rotary body for changing the direction of a component mounting section is fixed to a hollow rotary shaft with a flange. The hollow rotary shaft is provided in a hollow motor and rotated integrally with the rotary body by driving of the hollow motor. A wire extending from an electric component, which is provided in the rotary body for changing the direction of the component mounting section, is arranged in the hollow rotary shaft of the hollow motor. An end of the wire is fixed to the rotary body, and the wire is arranged with looseness or into a spiral in the hollow rotary shaft. Further a lateral surface of inside the hollow rotary shaft and a surface of a coupling shaft are coated with protective materials.

A guide belt is stretched over a drive pulley that rotates integrally with a head and a driven pulley situated at one side of the drive pulley. One end of the cable is fixedly attached to a part of the guide belt that is always in contact with the drive pulley when the head rotates, while the cable is extended along the guide belt. The cable is bent back in U shape at its midpoint and the cable on the other end side therefrom is extended along a guide member placed substantially in parallel with the guide belt between the drive pulley and the driven pulley. The other end of the cable is fixedly attached to the guide member.

The present invention provides an apparatus and a method for operating reflow soldering in a mounting field whereby an abnormality in transfer of circuit boards can be detected with high reliability. Whether or not a circuit board is transferred by a transfer conveyor is judged. A discharge conveyor is started when a control device judges occurrence of transfer abnormality. After the discharge conveyor starts, the transfer abnormality is determined to be a drop of the circuit board if a discharge completion detector detects that a dropped circuit board is discharged. And then the control device continues the reflow soldering. The transfer abnormality in the reflow soldering apparatus can be detected with high reliability because it can be detected whether the transfer abnormality is either the drop or a clog of the circuit board.

Disclosed is a carbon dioxide gas processing apparatus including an oxidization vessel for producing a magnesium oxide by oxidizing magnesium-containing powder in an atmosphere of a gas such as a carbon dioxide gas that contains oxygen as a constituent element thereof, a carbonate production tank that reserves water or a water solution therein and that introduces the magnesium containing oxygen as a constituent element produced in the oxidization vessel, and a carbon dioxide gas supplying means for supplying carbon dioxide gas to the carbonate production tank.
摘要:
A piezoelectric element is mounted to a clinch lever for detecting stress-strain generated therein when cutting and clinching leads of an electronic component that has been inserted in corresponding holes formed in a circuit board substrate. A detected voltage d is compared to a threshold voltage s selected from a plurality of threshold voltages preset in the device. When the detected voltage d exceeds the threshold voltage s, the insertion detecting section outputs a signal indicating that the insertion of the leads in the holes has been performed normally.

A photoconductive phthalocyanine composition is disclosed, comprising (A) a photoconductive phthalocyanine composition comprising 100 parts by weight of an unsubstituted phthalocyanine derivative and from 0.001 to 5 parts by weight of a nitro- or halogen-substituted phthalocyanine derivative and (B) from 0.01 to 10 parts by weight, per 100 parts by weight of the photoconductive phthalocyanine composition (A), of a phthalocyanine derivative having at least 4 electron attracting groups. A photosensitive layer formed of the photoconductive phthalocyanine composition produces digital signals whether input light is digital or not. It is useful as not only a photoreceptor for digital recording system of electrophotography but a photoreceptor for analogue light input in conventional PPC to provide a high quality image with sharp edges.
