Title: Selective formation of polyimide film
Inventor: YOSHIDA MASAHIRO
IPC: H01L23/31
Filed: 1993-12-25
Abstract: PURPOSE:To shorten processing time while making opening width uniform and to eliminate a possibility of generating crack in a resin for sealing by a photosensitive agent in polyimide films without increasing a curing temp. CONSTITUTION:After the photosensitive positive polyimide film 7 is formed, a nonphotosensitive polyimide film 8 is formed on its surface, by which the polyimide films of a two-layered structure are formed. A photoresist film 9 of a positive type is formed on the surface of the nonphotosensitive polyimide film 8. This photoresist film 9 of the positive type, the nonphotosensitive polyimide film 8 and the positive polyimide film 7 are patterned by exposing and developing to the photoresist film 9 of the positive type.

Title: Dynamic learning of adjacent radio cell
Inventor: CHAVEZ DAVID L JR
IPC: H04W36/08
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To easily specify a cell site seemed to be suitable for hand-off to each cell site by deciding a subset of an adjacent cell site to which activity transfer is attempted. SOLUTION: When a radio transmitter/receiver 117 starts moving from the cell 101, a system controller 118 selects cells 102 to 109 of the subset, examines signal intensity of the radio transmitter/receiver 117 and decides to which cell the transmitter/receiver is handed off. Furthermore, the system controller 118 extracts two other cells from the remaining cells at random and also examines transmission signal intensity of the radio transmitter/receiver 117. Since the transmission signal intensity is examined, the system controller 118 is capable of deciding whether or not the other cells are to be regarded as target cells from the cell 101. The system controller 118 is capable of deciding whether or not a new cell which is presently regarded as the target cell from the cell 101 actually exists by using the cell selected at random.
