Abstract: PURPOSE:To form the joint of a semiconductor chip and a wiring board into a flexible structure to prevent the generation of a thermal stress and to improve the reliability of a semiconductor device by a method wherein the connection of the chip with the board is conducted through foillike conductors provided on an organic film.

Abstract: PROBLEM TO BE SOLVED: To drastically reduce required read time and analysis time by dividing the read range of a line sensor into plural blocks in the direction of horizontal scanning while carrying a medium in the vertical scanning direction of the line sensor and reading a bar code in a block order. SOLUTION: When a position sensor detects a medium to which a bar code attached, a CPU notifies a line sensor controller of a read start instruction and the line sensor 5 starts to read the bar code 16. That is, when the A position of the code 16 comes just under the sensor 5, the reading of the sensor 5 is performed in an I block. When the medium undergoes one step carrying and the B position of the code 16 comes just under the sensor 5, a J block is read. After that, a K block is read at a C position, an L block is read at a D position, ...a P block is read at an H position. Thus, as many as one block is substantially read.

Abstract: PURPOSE:To enable high-speed sensing stable and with a reduction in power consumption by dividing a bit line into two groups, one for a Vcc precharging and the other for a Vss precharging. CONSTITUTION:A bit line couple divided into two groups is precharged at an earth potential Vss in a first group and at a power source potential Vcc in the second group.
