Title: Packaging for semiconductor chip
Inventor: UJIIE MASATO
IPC: H01L23/13
Filed: 1997-08-01
Abstract: The packaging (30) has a lower part with an upper side fastened to a chip (31). The packaging also has an upper part which makes a transition into a circumferential region of the upper side and which has several edge surfaces. These edges, together with a central region of the upper side, define a cavity (30f) to receive the chip. The edge surfaces form four corners which respectively correspond to the four corners of the chip. Several electrical conductors (30ea-30ed) are formed on an upper surface of the upper part around the cavity. These are connected to contact pads on an upper side of the chip by electrically conducting wires (30f). A number of pins (30g) are connected with several electrical conductors. At least one notch (30j) is formed in the upper part to cooperate with the four corners of the cavity so that one of the four corners of the chip can extend into the notch.

Filed: 1998-09-12
Abstract: The stirrer consists of a frame holding a motor whose shaft (5) runs between two stiffening strips (8) that carry a bearing (9) at their ends. Two flat blades (7) form the stirrer paddles. In operation the blades are passed through the floor slit until the wheels (11) touch the floor so that the stirrer can then be swiveled about them. The stirrer is slung by a strap (23) over a hook (30) at the end of the arm of a support frame.  Preferred Features: Depending on the stirrer used the fixings of strap (23) can be placed in a number of positions (22) on the motor frame so that the equipment is well balanced. The stirrer can be lowered manually or by a hydraulic cylinder (36) that swivels the support arm. In another version of the support frame, made as an inverted U from channels whose opening face each other, guide wheels are fitted outside wheels (11) of the stirrer to run inside the channels. This steadies the stirrer, especially when wire ropes are used to lower it.
