Title: Manufacture of flexible printed wiring board
Inventor: SUGANO MASAO
IPC: H05K3/46
Filed: 1990-01-29
Abstract: PURPOSE:To obtain a highly flexible printed wiring board at low cost by making through holes corresponding to a through hole section, laminating both faces of a flexible base material, plating only the through hole section, and peeling plating resist. CONSTITUTION:Double-layer films 6 which consist of cover lays 4 and plating resist 5 laminated thereon and have through holes made beforehand in the predetermined sections corresponding to a through hole section 3 are laminated on both faces of a base material 1 and then the laminated base material 1 is immersed in high-speed electroless copper plating liquid for the predetermined time to form a plating layer 7 only on the through hole section 3. Only the plating resist 5 composing the double-layer films 6 laminated on both faces of the base material 1 is peeled to obtain a double-sided flexible printed wiring board. Because the plating layer is thus formed only on the through hole section 3, the cost of plating liquid is reduced and a flexible printed wiring board of a high bending characteristic is obtained.

Title: Character string predicting method and device therefor
Inventor: TAMURA TOSHIYA
IPC: G06F17/22
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To preferentially display the prediction candidate of a high conviction degree and to realize an input operation of good efficiency through the use of input prediction. SOLUTION: A character inputted from an input part 101 is recognized in a character recognition part 103. In a dictionary retrieval part 107, a prediction character string is retrieved based on the combined character string of a recognized candidate character group and candidates are displayed by a prediction character string display part 111. A prediction character string learning part 112 registers the prediction character string which a user selects in a prediction character string learning dictionary 114. When the prediction character string which has been learnt exists in the candidates of the prediction character strings, which are obtained in subsequent inputs, the output order of the candidates is adjusted so that the pertinent prediction character strings are outputted with high priority by an output order adjusting part 108.  Thus, the prediction candidate of a high conviction degree can be obtained previous to the other candidates and efficient input can be executed.
