Abstract: PURPOSE:To incorporate a snubber circuit having a Zener diode controllable in Zener voltage in the same semiconductor element as a transistor by utilizing a small area by a method wherein the emitter-base junction of the transistor formed in the same isolation region to block the forward current of the Zener diode. CONSTITUTION:The transistor 6 is constructed of a p<+> diffused layer 17a, an n- epitaxial layer 15, and a p-type substrate 11, as a parasitic transistor. When the transistor 1 turns off, a current flows via p-n junction between the emitter region 11 or 13 and the base region 15 of the transistor 6 and via Zener diode 3 by an L load connected to a terminal 23. However, this current flows to the base of the transistor 6, i.e. the Zener diode 3 only by a reverse multiple of the factor of current amplification (alpha) of the transistor 6, and the rest flows to the earth via collector terminal 25. Thereby, the current capacitance of the Zener diode 3 is small, the area can be reduced, and further the control of the Zener voltage is enabled only by adjustment of the impurity concentration of the surface of a p<+> region 17b.

Title: Ribbon winding control device of printing device
Inventor: NAKAMURA SHIGEO
IPC: B41J33/34
Filed: 1990-06-12
Abstract: PURPOSE:To detect the joint of an endless ribbon easily without the installation of a special sensor by detecting load variations of a motor when the joint of the endless ribbon passes through a ribbon cassette outlet part as input current variations of said motor. CONSTITUTION:A tensioner 7A is installed near an outlet for a ribbon cassette 7 to adjust the tension of a ribbon 5 properly. When a joint 5A of the ribbon 5 passes through the tensioner 7A, the passage increases a resistance due to the larger thickness of the joint 5A, and this results in an increased load on a DC motor 14. Subsequently, an input current running to the DC motor 14 increases at the moment when the joint 5A of the ribbon 5 passes through the tensioner 7A. An A/D converter 23 is connected to the DC motor 14 and detects a voltage signal corresponding to an input current running to the DC motor. Then the converter 23 converts the voltage signal to a digital signal and outputs the digital signal to a microcomputer 22. As a result, a printing wire is prevented from sticking out at the joint of an endless ribbon.
