Title: Compacting method of powdered material and device
Inventor: KINOSHITA TOSHIHARU
IPC: B28B3/00
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To realize a high density and homogeneous compaction by filling up powdered materials in a compacting rubber mold in uniform density under the condition that the crosslinking of the powdered materials is avoided from developing by a method wherein the flexible compacting mold is made to pulse by passing a pressure medium therethrough at filling the powdered materials in the compacting mold. SOLUTION: During the filling of powdered materials from a powdered material feeding box 16 in a compacting rubber mold 4, a pressure medium in a pressure vessel 1 is vibrated periodically. Thus, the compacting rubber mold 4 is made to periodically pulse from its side surface through a pressurizing rubber mold 6 arranged on the outer periphery of the compacting rubber mold 4. As a result, the crosslinked portion among the powdered materials in the compacting rubber mold 4 is broken, resulting in annulling the uneven density due to crosslinking and, at the same time, the powdered materials are supplied from the powdered material feeding box 16, resulting in uniformly filling the compacting rubber mold 4. Thus, the powdered materials can be highly densely and homogeneously compacted.

Title: Apparatus for applying back tension to ink sheet
Inventor: ISHIMA KAZUMI
IPC: B41J33/52
Filed: 1989-05-08
Abstract: PURPOSE:To stably apply a back tension to an ink sheet for a long term by a construction wherein the torque of a drive member is controlled so that an elastic body connecting a back tension roller to a rotating shaft can be kept constant in displacement amount. CONSTITUTION:An ink sheet 1 is moved in a direction of an arrow A, and a maximum output voltage is obtained with a magnet 5 abutted on a Hall element 9. The voltage set in a gain adjuster is outputted from an amplifier, thereby being amplified in electric power to be applied to a motor so as to produce a force to rotate a roller shaft 3 in a direction of an arrow B. This force is transmitted to a pin 18 through a spring member 4, whereby the ink sheet 1 is tensed in a direction reverse to the travel direction A and applied with a back tension. At this time, the spring member 4 is bent leftward by the reaction force of the pin 18, which results in an extended distance between the magnet 5 and the Hall element 9, a lowered output voltage, and a reduced torque by the motor. The motor is actuated so that a predetermined distance can be established between the ink sheet 1 and the Hall element 9. In this manner, a constant tension is invariably applied to the ink sheet 1.
