  • Publication number: 20010008061
    Abstract: An apparatus for measuring a component that can carry out processes such as visual inspection, characteristic measurement, screening, and taping efficiently while transporting the electronic component at high speed. In order to transport the electronic components to the index table where the processes such as characteristic measurement, screening, and taping is carried out, a component transporting device is used in which the electronic component delivered from the component delivery section 10 is transported to the component intake port 23 based on negative pressure, transported with the airflow through the transportation path 25, and discharged from the part discharging port 24. The transporting device includes a gas discharging port 33 in the vicinity of the component discharging port, which serves to decrease the transport speed of the electronic component before transporting it to the index table.

  • Patent number: 4814938
    Abstract: A high voltage capacitor used for a low-pass filter circuit or the like in a magnetron oscillator circuit of an electronic cooking range includes in combination, a capacitor unit, a ground terminal into which the unit is inserted, two perforating conductors inserted through two through-bores extending in the capacitor unit, insulating casings encircling the capacitor unit on both sides of the ground terminal, insulating resin disposed in both of the insulating casings and surrounding the capacitor unit, an electrode at the outer periphery of the capacitor unit, and electrodes at the inner periphery of each through-bore which surround and are conductively coupled to each perforating conductor. When compared to a conventional high voltage capacitor, the present invention has a reduced number of components, is simple in construction, and is not subject to a lowering of the breakdown voltage durability caused by a heat cycle or the like.
