Title: Heat-sensitive recorder
Inventor: ISHIKAWA YUUJI
IPC: B41J2/36
Filed: 1982-08-05
Abstract: PURPOSE:To enable to prevent a thermal head from being overheated, by changing the width of a recording pulse for the subsequent copy in accordance with the temperature of a thermal head each time the recording of a sheet of copy is started or finished, in a facsimile or the like. CONSTITUTION:When starting recording of the first copy, the initial temperature of the thermal head H is detected by a sensor TS. According as the initial temperature detected is higher or lower than a preset temperature, an image signal controlling part C feeds a recording pulse having a short or long width to image signal controlling transistors Q1-Qn, whereby heating elements R1-Rn are supplied with an electric current in accordance with the pulse width, resulting in printing. When it is necessary to continuously record the subsequent copy, the temperature of the thermal head H is detected again, and the pulse width for the subsequent copy is determined in accordance with the temperature detected. Accordingly, overheating of the thermal head can be sufficiently prevented by a simple circuit construction and a simple control, and it is enabled to eliminate a sharp density change in recording a sheet of copy.

Filed: 1978-11-07
Abstract: PURPOSE: To prevent the damage of a rotor conductor casued by thermal stress at the time of starting by inserting a slit into the portion outside the iron core of the rotor conductor.  
     CONSTITUTION: After driving in the rotor conductor 12 to the slot of a rotor iron core 11, the slit 15 which divides the height of the conductor 12 into, for instance, three equal parts is provided in the portion 12 outside the iron core 11. At one end of the conductor 12 a short-circuiting ring 13 is uniformly welded thereon. On doing this, due to the difference in temperature produced between the upper and lower sides of the conductor 12 as the result of the skin effect at the time of starting, even if the portion of the conductor 12 outside the iron core 11 is affected by heat stress, the conductor can freely be transformed, and the damage such as a crack can be prevented because the stiffness of the conductor 12 divided by the slit 15 is low. As excessive force is not added to the portion where the short-circuiting ring 13 has been welded, the welded portion is also prevented from being damaged.
