Abstract: Disclosed is a cable television system including a broadcasting center and terminal devices. When a notification data is to be transmitted to each terminal device, the broadcasting center transmits a channel data indicating a channel through which the notification data is transmitted. The terminal device, upon receipt of the channel data, stores the channel data in a memory. When the terminal device is turned OFF, the last viewed channel number is stored in the memory. When, the terminal device is turned ON, if the channel data transmitted from the broadcasting center is stored in the memory, the terminal device is tuned in the channel indicated by the channel data, while if the channel data is not stored in the memory, the terminal device is tuned in the last viewed channel.

For this objective, the wiring pattern generation unit generates a wiring pattern as the information for specifying an in-area wiring route to be wired in each row and an in-area wiring route to be connected to the next row among the solder ball connection pad area closer to the wire bond pad area, based on the design conditions of the wiring route stored in the design condition memory. Then, the wiring plan generation unit generates a wiring plan laying out the plurality of wiring routes by combining the wiring patterns generated for each row, and the wiring rule check unit selects some of the generated wiring plans suited for the wiring rules and generates the plurality of wiring candidates.

Abstract: To determine leadframe tip positions, a circular arc portion where leadframe tips are to be arranged is determined so as to be opposed to each of the four corners of a die pad by performing a search. Then, straight line portions are set so as to extend from the circular arc portion and to be opposed to the die pad sidelines. The shape of each leadframe tip on the circular arc portion is defined as a region that is sectioned by two concentric circles and two radial rays extending from the center of the concentric circles. The division between the circular arc portion and straight line portions and the setting of the center of the circular arc portion are performed automatically. The leadframe tip width and interval are determined independently of each other.

Abstract: In a lead frame, L-shaped support tapes are applied to inner leads and suspension leads. Ends of the support tapes are overlapped with each other at the suspension leads to form, together, a rectangular ring shape. Since the support tapes are L-shaped, when the overlapped portions are positioned at the suspension leads, there are only two overlapped portions of the support tapes at the suspension leads. Thus, the number of overlapped portions requiring accurate alignment is reduced. Moreover, the L-shaped support tapes can be cut from the material for the support tape with higher efficiency.
