Title: Clock generating circuit
Inventor: SAKAI YASUHIKO
IPC: H03K3/017
Filed: 1988-07-12
Abstract: PURPOSE:To obtain a clock generating circuit of high precision by using a constant current circuit to charge a capacitor. CONSTITUTION:When a low potential (L) is inputted to a gate input terminal 2 of an N-type MOS transistor TR, a capacitor 7 is charged by a power source 8, but the charging speed of the capacitor 7 is fixed because it is charged through a P-type J-FET 5 and 6 of a constant current element 6. When reference voltages of comparators 26-33 are increased in a certain proportion, outputs of comparators 26-33 are successively changed from L to H (high potential) at intervals of a certain time. When control input terminals 34-41 are set to H at this time, input terminals 52-59 of an odd/even discriminating circuit are changed from L to H at, intervals of a certain time. Thus, a clock is obtained where the pulse width has the duty ratio changed in one period.

Title: Driver circuit for thermosensitive recording head
Inventor: SUGI AKIHIKO
IPC: B41J2/35
Filed: 1979-12-29
Abstract: PURPOSE:To control the dispersion of the color formation of thermosensitive paper and to improve the quality of a printing picture by constantly holding voltage applied to a plurality of resistors of a thermosensitive recording head. CONSTITUTION:A compensation circuit RS is mounted which compensates a change of saturated voltage VCES(QC) between a collector and an emitter of a transistor QC for controlling common signals and constantly keeps applied voltage  V(R1-Rn) to resistors R1-Rn, and the impedance of the compensation circuit RS  is controlled by means of a comparator CP. The comparator CP detects the number  of picture signal controlling signals put out from a picture signal controlling section  C1, and generates signals decreasing the impedance of the compensation circuit RS  when the picture signal controlling signals are many and signals increasing the  impedance of the compensation circuit RS when they are, on the contrary, few.  Thus, the dispersion of the calorific power of the resistors R1-Rn diminishes, and  the quality of a printing picture is improved.
