IPC: B41J2/36
Filed: 1980-03-10
Abstract: PURPOSE:To simply and inexpensively keep a printing density of a thermal printer constant, by a method wherein a dummy resistance is mounted at a thermal head in a printing density control circuit. CONSTITUTION:If, for example, a printing signal PT is inputted, an expotential function waveform as shown in a signal Pa is obtained at a point (a) by means of a dummy resistance R0, a resistance r0, and a capacitor (c). If the signal Pa reaches a switching voltage V0 of a transistor TR1, the transistor TR1 closes and a signal having a signal width t0 as shown in a signal Pb is obtained at point (b). Furthermore, through the aid of a transistor TR2, a voltage value Vp as shown in a signal Pd and a thermal driving signal having the pulse width t0 are obtained. If each resistance value of the thermal head is higher than a standard, or a resistance value of the dummy resistance R0 is high, the waveform of the signal Pa inclines slowly, and the pulse width t0 is lengthened. A printing density is proportioned to the product of an applied power and a pulse width, and thereby a constant printing density can be obtained.

Title: Semiconductor integrated circuit device
Inventor: HONMA TAKESHI
IPC: H01L23/52
Filed: 1990-02-08
Abstract: PURPOSE:To reduce a crosstalk noise and to reduce the increase amount of a chip area by a method wherein a conductive guard line at a ground voltage level is arranged in such a way that at least one part is sandwiched between signal interconnections and one or more patterns of such an arrangement are formed. CONSTITUTION:A guard line 2 is provided with a ground voltage level and is situated between a signal interconnection 1 and a signal interconnection 3. When the line width W2 of an intermediate line is changed in such a three- line shape, a crosstalk noise between lines at both ends can be reduced even when the width of the intermediate line is narrower than the width of the lines at both ends. Consequently, when a signal is changed on the signal interconnection 1, it is possible to reduce a crosstalk noise generated on the signal interconnection 3 even when the line width of the guard line 2 at the ground voltage level is smaller than the line width of the signal interconnections 1, 3. Thereby, it is possible to obtain a semiconductor integrated circuit device which can reduce the crosstalk noise and which can reduce an increase in an area by arranging the guard line.
