Abstract: PURPOSE:To obtain a weighted product sum by providing an adder which uses the output of a multiplier and the output of a barrel shifter which can optionally control the shift bit number as the inputs and a register which holds the output of the adder and has the output used as the input of the barrel shifter. CONSTITUTION:The first multiplicand a0 and multiplier b0 are inputted to a multiplier 1, and the product a0b0 is outputted from the multiplier 1 and added with the contents 0 of a register 3.

Thus the register 3 has the new contents 2<m1>a0b0+a1b1. Then the multiplicand a2 and the multiplier b2 are inputted with the next product sum with the shift value of the shifter 4 set at m2 bits. Thus the contents of the register 3 are set at 2<m2>(2<m1>a0b0+a1b1)+a2b2. Hereafter the contents of the register 3 are doubled in the same way with the i-th product sum and added repetitively with the product a1b1. In such a way, the weighted product sum is obtained.

Title: Target error spot positioning method for automatic mdf device
Inventor: WADA SHIGETO
IPC: H04Q1/14
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of the holding and inserting mistakes of a connection pin and to improve the quality of an automatic MDF device by detecting the center coordinates of a reference mark, using the collected data for calculation of the correction value, dividing a target error spot, using the data closer to the target error slot to correct the position of the target error spot, and positioning the target error spot. SOLUTION: A target error spot is divided into tow parts in a single direction, and the center coordinates of the reference marks 1 to 4 which are set in coordinates are detected. Then two base axes separate from each other (X direction: Xa and Xb, Y direction; Ya and Yb) are applied for correction in each direction. The correction value is calculated based on a reference axis closer to the target error spot, and the target error spot is positioned. In other words, two data are measured in each direction and the correction value is calculated from the data closer to the target error spot. Based on the calculated correction value, a connection pin is inserted and pulled out. Thus, it's possible to position the target error spot with high accuracy, to significantly decrease the holding and inserting mistakes of the connection pin and also to eliminate the problem of quality.
