Title: Thermal recoding medium
Inventor: MORONUKI KATSUMI
IPC: B41M5/337
Filed: 1988-05-12
Abstract: PURPOSE:To prevent a dust application to a thermal head to obtain an image having a superior dot reproducibility and a high sharpness, by incorporating specific polynorbornene particles in a thermal recording layer. CONSTITUTION:A thermal recording medium has a thermal recording layer containing a colorless or light-colored color forming substance and a color developer coloring the color forming substance under heat. In the thermal recording layer, polynorbornene particles shown by a formula I are incorporated. The polynorbornene particles in particle form are obtained by a method in which a norbornene is synthesized by the Diels-Alder reaction of ethylene and cyclopentadiene and this norbornene monomer is ring-opening polymerized. The remarkably porous structure and rapid hot melt substance absorptivity of the polynorbornene particles produce remarkable effects on the improvement of image sharpness, dot reproducibility, and head running properties in a thermal recording.

Title: Output circuit
Inventor: KUNIEDA MITSUYUKI
IPC: H03K17/18
Filed: 1986-05-19
Abstract: PURPOSE:To reduce the effect of noise generated in a power wire onto other circuit without slowing down the speed of an output signal by constituting the titled circuit by two power terminal pairs, two buffer circuits connected to them respectively, a common output terminal for both the buffer circuits, a signal delay means connected to an input terminal and a control means controlling the operation of the buffer circuits. CONSTITUTION:The buffer circuits 15, 16 outputting a signal IN generated in the inside of an IC are connected between power terminals 11 and 12 and between terminals 13 and 14. A control circuit 18 receives the signal IN and an output signal of an input delay circuit 20 retarding the signal IN by a prescribed periodtau, if the level of both the signals differs, only the circuit 15 is operated in response to the signal IN to set the level of the output signal OUT, and when the level of both the signals is equal, only the circuit 16 is operated in response to the input signal IN. Only when the circuit 15 is opeated and the level of the signal OUT is set, a noise is generated between the power terminals 11 and 12. Since the circuit 16 is inoperative, no noise is generated between the power terminals 13 and 14. Since the output terminal 17 is driven sufficiently by the circuit 15 with the level of the signal OUT changed, the speed of the signal OUT does not slow down.
