Title: Constant multiplier, method and device for automatically generating constant multiplier, and storage medium stored with automatic constant multiplier generating program
Inventor: KOSUGI KAZUYUKI
IPC: G06F7/52
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To decrease the number of partial products based upon a constant, and reduce circuit area and shorten an operation delay time by decomposing a constant as a multiplicator into the least number of addition and subtraction terms, and adding and subtracting all partial products obtained by multiplying the respective terms of the addition and subtraction by a multiplicand. SOLUTION: A constant I and a signal A as an arbitrary value are multiplied by each other. Then the constant I as the multiplicator is decomposed into the least number of addition and subtraction terms and a constant multiplier 10 is generated and designed according to the decomposition results. For example, when the constant I is 59, the constant I=59 as a multiplicator is decomposed into the least number of addition and subtraction term '2<6> -2<2> -2<0> ' of power of '2', the respective terms of the addition/subtraction terms are multiplied by the signal A as the multiplicand, and all obtained partial products are added and subtracted by adders 1 and 2 and inverting circuits 3 and 4 to obtain the multiplication result of the constant 59 and signal A. Therefore, the number of addition stages of the constant multiplier 10 and the number of adders in use can be minimized.

CONSTITUTION:For eliminating the influences of the on-resistances of dual switches C1, C1'...Cn and Cn' composed of the MOS transistors, a resistance 2R is divided into resistances having two resistance values R, and a switch VDD by the MOS transistor which is always in the on-condition and, simultaneously, whose on-resistance is equal to the on-resistances of the switched C1, C1'...Cn and Cn' is connected in series to each of two among three resistances R. To the other one, the on-resistances of the MOS dual switches C1, C1'...Cn and Cn' are supplied. When the on-resistance of the switch by the MOS transistor is made into an (r), the resistance to see the right and the resistance to see the below from the connecting point An are made equally into 2R+2r, and a synthetic resistance to simultaneously see the right and below from the connecting point An is made into R+r. A feedback resistance Rf of an arithmetic amplifier 62 is made into R+r.

Filed: 1991-06-07
Abstract: PURPOSE:To prevent decreases in bondability and wettability of outer leads by making Au plating peeled off immediately under tin-lead solder alloy plating of an outer lead part so that a Cu layer can be provided on the base of the alloy plating. CONSTITUTION:Before an outer lead part 12 is coated with tin-lead solder alloy plating 16, a Cu plane as a base 10 located at the part to be coated with the tin-lead solder alloy plating 16 is exposed once; then, this place is coated with the tin-lead solder alloy plating. Therefore, even in the case of a heat treatment inevitable during the IC manufacture process, diffusion phenomenon does not develop between this Au plating 15 and the tin-lead solder plating 16. This process avoid formation of an Au-Sn alloy layer, thereby enabling outer leads 12 to be prevented from markedly decreasing in bondability and wettability.

Title: Picture recording device utilizing stepping motor
Inventor: YAMAZAKI HIROHIKO
IPC: G03G15/04
Filed: 1986-07-12
Abstract: PURPOSE:To prevent deterioration of print quality due to damping of a stepping motor by discontinuing a printing action until a feed signal is sent from a printer controller. CONSTITUTION:A horizontal synchronizing signal HS is sent to a printer controller and a timer 33 as a synchronizing signal of the print starting position respectively. A feed signal FS is outputted in response to the signal HS and the print data VD is processed as an effective form. A clock CLK which drives a stepping motor 31 is outputted with the same timing as the data VD according to the control of the timer 33. A recording medium 21 is carried by a prescribed amount in a print mode. The Q output FF is used as the gate signals of AND 28 and 29 for control of supply of a clock CLK' to the motor 31 as well as the print data VD' on an AOM 7. Thus a printing action is kept halted until the print data equivalent to a line are stored in a memory.
