Title: Production system for control transfer function to master load module
Inventor: MATSUDA RYUICHI
IPC: G06F9/45
Filed: 1989-02-16
Abstract: PURPOSE:To easily call a master load module by using a shared data table production means, an execution mode shared data table production means, and an overlapping means. CONSTITUTION:A shared data table production means 31 produces a shared data table to define an inlet variable in a master load module 5 and a subload module 6 respectively. An execution mode shared data table production means 71 allocates (produces) an execution mode shared data table based on the shared data table contained in the module 5 to define the inlet variable to a memory at execution. An overlapping means 81 puts the shared data table of the module 6 on the execution mode shared data table when the module 6 is dynamically linked to the module 5. Thus an execution mode memory 9 is obtained. As a result, the control is transferred to the module 5 from the module 6 with no succession required for an inlet point.

Title: Impact head
Inventor: YAMAMOTO KAZUHIKO
IPC: B41J2/235
Filed: 1989-02-17
Abstract: PURPOSE:To obtain an impact head which realizes stable operation of an armature in a wide range of temperatures by allowing said armature to collide against a high molecular elastic material having superior impact energy absorbability at high temperatures after a high molecular elastic material having superior impact energy absorbability at low temperatures is slightly deformed. CONSTITUTION:A dumper 20 is constituted of a high molecular elastic material 20a which is superior in absorbing impact energy at low temperatures and a high molecular elastic material 20b which is superior in absorbing impact energy at high temperatures. The elastic material 20a protrudes slightly more toward an armature 6 than the material 20b. This protruding amount of the elastic material 20a is approximately equal to the amount of deformation thereof caused when the armature 6 collides against the material 20a at low temperatures. After printing, a printing wire 2 is returned by the spring force of a return spring 10, and collides against the dumper 20. At high temperatures, the elastic material 20a becomes soft because of the characteristic of the high molecular elastic material, so that the deforming amount becomes large, whereby the elastic material 20b receives the collision of the armature 6.
