Title: Voltage comparator circuit
Inventor: YAMAMOTO YUJI
IPC: H03K5/08
Filed: 1987-10-23
Abstract: PURPOSE:To reduce power consumption of a voltage comparator without increasing the number of element by controlling the connection between a differential stage and a load circuit by means of a switch controlled by a control signal. CONSTITUTION:NMOS transistors; M4-M7 change over M2 and M3 of a differential input stage and M8 and M9 being its load circuit. Just after a switching control signal CLK 1 goes to a high logic level, voltages V10, V11 and V8, V9 change rapidly to change a voltage at input terminals 4, 5 through the stray capacitance between the gate and drain electrodes of the M2, M3. Thus, the timing when the input starts changing comes after a prescribed time elapses after the CLK 1 goes to a high logic level. Since the current flowing to a load TR is made zero, useless power consumption is suppressed.

Title: Thermal transfer recorder
Inventor: UEDA HIROO
IPC: B41J2/32
Filed: 1985-11-27
Abstract: PURPOSE:To enable a sharp transfer recording to be always conducted with an adequate density, by a method wherein a thermal head is mounted on a bimetal and a pressing force of the thermal head against a platen is made to vary depending on an ambient temperature. CONSTITUTION:A thermal head 4 having a plurality of heating portions is pressed up against a recording paper 2 set along a platen 1 through a hot melt ink ribbon 3, and installed on a head holder 5 through a bimetal 11. Therefore, at an ordinary ambient temperature, the thermal head 4 is free from displacement, but if a temperature goes higher than the ordinary, in proportion to the temperature the bimetal 11 displaces in a direction P to slightly decrease the pressing force against the recording paper 2, which enables a sharp printing fuel from bleeding and being rubbed off to be transfer-recorded. On the other hand, if an ambient temperature decreases, in proportion to the temperature the bimetal 11 displaces in a direction Q to slightly increase the pressing force, which improves the conventional low and unclear printing density to have an adequate density. In this manner, a sharp printing can be transfer-recorded.

Title: Synchronization protection test circuit
Inventor: MUROI KIYOSHI
IPC: H04L7/08
Filed: 1985-11-28
Abstract: PURPOSE:To make the titled circuit suitable for a high speed operation with a simple circuit constitution by providing a gate circuit gating a transmission line signal input inputted to a circuit to be tested by synchronizing step-out signal output outputted from the circuit to be tested. CONSTITUTION:When the synchronizing step-out signal 8 goes to logic '0', the output of a NOR gate 6 goes to logic '1', the output of a gate 7 inputting a transmission line signal input 1 is inhibited by a wired OR 9 and the input signal 3 of a synchronizing circuit 4 goes to logic '1'. Since the synchronizing circuit 4 cannot take synchronization, the synchronizing step-out signal 8 goes to logic '1' after a forward protection time T1 elapses (time t2). The output of the NOR gate 6 goes to '0' and the transmission line signal input 1 becomes the input signal 3 of the synchronizing circuit 4 as it is through the gate 7 and the wired OR 9. Since the synchronizing circuit 4 takes synchronization immediately at the frame synchronization pattern position (time t3), the synchronizing step-out signal 8 goes to logic '0' after a backward protection time T2 elapses (time t4).
