Abstract: The invention provides a production method for an insulated semiconductor device which eliminates displacement between positions of upper and lower metallic mold cavities (between upper and lower caps) when a resin is filled to achieve improvement in quality and productivity. A lead shaping apparatus for shaping inner lead portions of a flat hoop frame supplied thereto from a frame supply apparatus is located between the frame supply apparatus and a die bonding apparatus so that, before die bonding of semiconductor pellets is performed, shaping of the inner lead portions is performed. Thereafter, die bonding and wire bonding are performed for the flat hoop frame, and then, resin is filled only into a lower metallic mold cavity by a resin filling apparatus to embed the inner lead portions in the resin.

Abstract: A wide-angle objective lens is comprised, from the object side, of a first lens component which is a negative meniscus lens having its convex surface facing the object side, a second lens component which is a meniscus lens having its convex surface facing the object side and having positive refractive power, a third lens component which is a cemented meniscus lens comprising a positive lens and a negative lens cemented together and having its convex surface facing the object side and having positive refractive power, a fourth lens component which is a positive meniscus lens having its concave surface facing the object side, and a fifth lens component which is a negative meniscus lens having its concave surface facing the object side. The wide-angle objective lens has a stop disposed between the second lens component and third lens component, and satisfies predetermined conditions.
