IPC: H01L21/56
Filed: 1993-08-17
Abstract: PURPOSE:To enable mounting of a semiconductor device and substrate, which was not possible according to the conventional structure of the semiconductor device, by a method wherein the interval between tip parts connected to an external board is made wider than the interval between root parts of outer lead parts. CONSTITUTION:An IC chip and inner leads are connected by conductive fine wires, and the inner leads are extended and used as outer leads 2. In addition, a sealing resin 1 covers parts up to the inner leads, and the outer leads are extended toward the outside from the sealing resin 1. At this time, the interval D in parts mounted on a board of the outer leads 2 is made wider than the interval C between parts of the outer leads 2 extracted to the outside from the sealing resin part 1, and the relationship between the intervals C and D is set as C<D. Thereby, the trouble with alignment which has been a problem in the mounting of a semiconductor device in which the interval between mounting positions of the outer leads 2 is a narrow pitch in a product by conventional techniques is relaxed, and a solder bridge is hardly produced.

Title: Image controller
Inventor: NAKAYAMA TOICHI
IPC: G03G21/00
Filed: 1985-09-17
Abstract: PURPOSE:To make a complicated image processing even in the electro photographic method by controlling the form feeding speed in a transfer part independently of the rotative speed of a photosensitive body. CONSTITUTION:The picture on an original 11 is exposed 4 times continuously and a form 4 is fed out in the same speed as a photosensitive body 3 only for a part of the picture and is stopped for the other part. That is, the photosensitive body 3 is raced in about one cycle for each of 3 blank parts 12. The light is preliminarily projected to these parts by an erase lamp 5 to erase unnecessary images so that an unnecessary toner is not stuck to the surface of the photosensitive body 3 when the form 4 is stopped or fed fast. Though the blank 12 of the form 4 requires a certain width and cannot be very narrow because a transfer part where a transfer charger 9 exists has a certain width in the form carrying direction, this controller endures general practical use if blank parts have a width set in a copying machine at present.
