IPC: B22C15/02
Filed: 1990-06-07
Abstract: PURPOSE: To facilitate the production of a core of an intricate shape having high hardness by putting green sand into a pressure die and precompressing the green sand in the pressure die by using a liquid pressure press, then subjecting the green sand to finish compressing. CONSTITUTION: An upper die tool 8 of a liquid pressure press 1 has an intricate die cavity 9 and a groove hole 11 communicating with the die cavity 9.

Title: Print head
Inventor: HARADA MINEO
IPC: B41J2/28
Filed: 1982-08-27
Abstract: PURPOSE:To ensure a stable print quality by varying the distance between the pressing point of a spring member and the rotary fulcrum of a magnetic member by a means of pressing in the direction roughly opposite to the impact force in a wirematrix printer. CONSTITUTION:As a printing current flows through a coil 15, an attraction member 9 protruding from a print wire 4 is turned by a charged spring force of a spring member 10 set by a screw 19 with the angle 9B thereof as rotary fulcrum and a printing is done. Since this spring member 10 varies in the spring constant as the range of the thickness and soldered fillet 21 changes, the pressing point with a spherical section 20 at the tip of a screw 19 is moved by DELTAL depending on a deflection value theta at the end of the spring member 10 so that the distance L to the pressing point from the rotary fulcrum 9B is varied by DELTAL with the pressing force to compensate for the variation in the spring constant. Thus,the print quality can be stabilized while the contact between a hole 11 of the spring member and a screw spherical section changes thereby minimizing the advance in wear and ultimately reducing the aging.
