  • Patent number: 6661641
    Abstract: In a terminal member, a protuberance is formed so as to protrude toward an external electrode, and thereby, a bonding portion where the terminal member is bonded to the external electrode, the bonding portion being formed with solder, is extended substantially linearly across a part of the external electrode. Preferably, the direction in which the bonding portion is elongated linearly is in parallel to that in which internal electrodes are extended. Further, it is preferable that the bonding portion is as wide as possible, and the center of the bonding portion in the width direction is as near to the center of the end-face of the capacitor body as possible.

  • Patent number: 6518632
    Abstract: A ceramic electronic part wherein widths of portions of external terminals that are joined to end surfaces of a ceramic electronic part element are made equal to or less than widths of internal electrodes disposed in the ceramic electronic part element. The joining portions of the external terminals are joined to the end surfaces of the ceramic electronic part element so as to be positioned within areas of the end surfaces of the ceramic electronic part element where the internal electrodes are exposed when viewed in a plane. The ceramic electronic part with the external terminal is a highly reliable one and makes it possible to prevent cracking of a ceramic part element even when the ceramic electronic part is large.

  • Patent number: 6285836
    Abstract: The low-cost, space-saving process cartridge identification mechanism identifies many types of process cartridge without requiring a new electrical logic circuit. Even if a pressing piece goes into a detection portion, switches are not turned on and hence a mounted process cartridge is not detected as long as the pressing piece does not push down a manipulation lever. Identification pieces are provided in an identification unit separately from the pressing piece. In this manner, a mechanism for mechanically identifying a process cartridge based on whether the identification pieces are interfered with by the interference pieces irrespective of turning-on/off of the switches. As a result, by combining combinations of the pressing piece and the manipulation lever and combinations of the identification piece and the interference piece, many combinations of an image forming apparatus and a process cartridge can be obtained at a low cost with space saving without requiring a new electrical logic circuit.
