Patent JP-H0383085-A (JP)
Title: Recorder
Inventor: KOBAYASHI KAZUO
IPC: G03G15/16
Filed: 1989-08-28
Abstract: PURPOSE:To eliminate base fogging by applying a signal obtained by converting an electrical signal into a heat signal to a toner carrier containing a heat- friction altering substance on its surface and selectively raising a friction coefficient so that toner attaches to the surface. CONSTITUTION:When a toner roller 1 is rotated and driven counterclockwise, an electric signal is applied to a thermal head 1. Then, a heating part 7 selectively emits heat, and the temperature of the external layer 4 of the facing toner roller 1 rises to raise the friction coefficient for toner T. Namely, the heat signal obtained by converting the electrical signal is applied to the external layer 4 composed of the heat-friction coefficient altering substance to selectively raise the friction coefficient of the surface according to the electric signal. Then, the toner carrying force of this part is improved to attach the toner T in a toner hopper 5. The toner is carried out of the hopper 5 after passing through the top of the thermal head 6. Consequently, only a desirable toner image TI is formed on the toner roller 1 and transferred onto a transfer material 9. Thus, base fogging never occurs.

Title: Thermal fuse
Inventor: TAKATSU TAKAO
IPC: H01H37/76
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a thermal fuse which is surely OFF at a set temperature to cut off a current by deforming a contact plate made of shape memory alloy into a form to cut off at a temperature of vaporizing a thermal pellet or a temperature around it. SOLUTION: A thermal pellet 1 and an on-spring 6 press a contact plate 2 in ON state to connect the plate 2 to an electrode 3. Since the temperature of a thermal fuse is raised in OFF state, the pellet 1 is vaporized. The force for pressing the plate 2 of the spring 6 is weakened, and the plate 2 is pressed by an off-spring 7, and separated from the electrode 3. Thus, a current is interrupted and disconnected to protect a circuit. When the current is not disconnected even when the pellet 1 is lost, the temperature becomes high by overcurrent to fuse the plate 2 to the electrode 3 so that it can not be separated by the pressing force of the spring 7, the plate 2 remains to be connected to the electrode 3.  However, the contact plate 2 made of shape memory alloy is deformed by the temperature rise, and the periphery of the plate 2 is separated from a case 4, and the electric connection is interrupted.
