Title: Electrostatic recorder
Inventor: SUZUKI KOUJI
IPC: G03G15/02
Filed: 1978-08-24
Abstract: PURPOSE: To prevent the formation of unstable recording images by announcing the degradation of a recording medium by the surface potential detection output on the recording medium.  
     CONSTITUTION: When a sensor motor driving signal inputs to terminal 1, a control circuit CT1 operates to run a copper 83 by means of a sensor motor 82, whereby the AC voltage of the amplitude prportional to the absolute value of the surface potentials of a recording medium 47 is obtained. This voltage goes through an amplifier circuit CT2 and a synchronous clamping circuit CT4 and is made to a DC voltage in a smoothing circuit CT5. This voltage then inputs the respective holding circuits CTs 7,8,9 of the standard bright part surface potential vL, bright part surface potential VL and dard part surface potential VD. The output of the CT7 outputs to terminal 2 and the outputs of the CTs 8,9 input to a display circuit CT10, where they are compared with the output of the CT2. When the surface potential contrast voltage (VD-VL) is below the specified value, the LEDs 7,8 are lighted to announce that the stable images are unobtainable. Hence, the formation of unstable images is prevented.

Title: Thermal printer
Inventor: ISHIMA KAZUMI
IPC: B41J29/377
Filed: 1987-04-28
Abstract: PURPOSE:To reduce the thermal effects of a rise in the temperature of heat generating elements to be affected upon adjacent dots, by providing a substrate of a thermal head with a cooling-liquid passage in proximity to a plurality of heat generating elements, and causing a magnetic fluid to flow through the circulating passage as the cooling liquid, thereby forming a magnetic field across the thermal head. CONSTITUTION:When printing is started, the temperature of heat generating element 7 is rapidly raised, and heat is transferred to an ink sheet 5 and also through a head substrate 12 to a magnetic fluid at a point P. The magnetic exceeded, upon which the fluid at the point P is moved in the direction of an arrow B by being pushed by a force generated by a magnetic force of the fluid at a part not yet heated. Since the fluid at a low temperature is supplied through a circulating passage 10 to the point P, the heat generating element 7 is rapidly cooled. Thus, a heat-dissipating effect is poor during printing because a cooling liquid does not flow, but the effect is rapidly increased when printing is finished, so that high-speed printing with high thermal efficiency can be performed.
