Title: Aluminum extruding parts and its manufacture
Inventor: HATTORI KAZUNORI
IPC: B21C26/00
Filed: 1995-01-24
Abstract: PURPOSE: To execute efficiently extrusion by forming a film superior in aluminum resistant adhesion on the surface of aluminum extruding parts by means of electric discharge coating and thereby preventing adhesion of aluminum to the aluminum extruding parts. CONSTITUTION: An aluminum billet 1 is inserted in a container 2 with a pressure applied between a stem 3 and a die 4, and an aluminum product with a specific cross-section is extruded from a die hole provided in the die 4. A dummy block 5 is attached to the tip end of the stem 3 for extruding the aluminum billet 1. This serves a purpose such that, when a damage such as deformation occurs due to a high stress produced at the time of extrusion, only the dummy block needs to be changed without changing the whole stem. Accordingly, extrusion of aluminum alloy is performed using the dummy block 5 which is coated with a cermet material by electric discharge coating, reducing the number of times for applying a release agent on the end face of the aluminum alloy billet to approximately one tenth.

Title: Inking mechanism for printer
Inventor: OBARA JUNJI
IPC: B41J27/10
Filed: 1990-02-08
Abstract: PURPOSE:To apply ink appropriately and uniformly onto a type and to eliminate ink blot or missing of character by providing a transfer roll with pores. CONSTITUTION:In order to apply ink onto a type 8a, a step motor 6 is actuated at first in the direction of an arrow A so that a type drum 7 is driven in the direction of the arrow A together with the motor 6. At the time, a transfer roll 4 is rotated in the direction of an arrow B by a driving force transmitted from a type drum gear 7b to a transfer roll gear 12. At the same time, an ink roll 2 is rotated in the direction of an arrow C by frictional force between the ink roll 2 and the roll 4 and thereby the ink impregnated in the roll 2 is transferred through the roll 4 onto the type 8a. At this time, even if the type drum 7 rotates more than single revolution to repeat application of ink onto the type 8a, pores 22 in the roll 4 absorbs the ink and holds it in place thus preventing excessive ink supply.
