Title: Mold for injection molding
Inventor: NISHIDA SHOZO
IPC: B29C45/38
Filed: 1990-03-13
Abstract: PURPOSE:To enable gate cutting motion and to eliminate the need for an exclusive hydraulic system and to enhance production efficiency by moving both molds for a gate cutting member in a state wherein both molds are closed before mold opening motion. CONSTITUTION:After cooling is completed, operation is shifted to a mold opening stage and a movable-side mold 4 starts to be retreated in the left direction. In accordance therewith, a fixed-side mold 2 is moved to the limited position in the left part by a die lock mechanism 6 while the mold 2 is joined to the movable-side mold 4. In the meantime, a gate cutting member 12 is pressed in the right part by a spring 14 and allowed to stand together with a fixed mold fitting plate 30 and a sprue bush 8. A gate part 50 is sheared by the edgelike tip part of the gate cutting member 12 by this relative movement. A molded form 24 is cut off from a sprue part 52. When the movable-side mold 4 is furthermore retreated, both molds 2, 4 are separated from the joined state due to the die lock mechanism 6. Only the movable-side mold 4 is retreated and mold opening is performed.

Title: Information recording and reproducing apparatus
Inventor: TANAKA YOICHIRO
IPC: G11B5/02
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent information from being lost due to thermal fluctuation while realizing a high recording density by detecting reference information which indicates change over a lapse of time in information recorded on a recording medium and, when the reference information is determined to indicate a predetermined value, rerecording information corresponding to the reference information on the recording medium. SOLUTION: When recording and accumulation of information starts, a reference signal is recorded on a reference signal region 25 by a magnetic head 1. At the same time, a recording time at which the reference signal is recorded is stored on a non-volatile memory 5 via a host interface 10 based on external time information. A reference signal monitoring section 26 stores a change in quality of the reference signal over a lapse of time on the non-volatile memory 5, and informs a hard disk controller HDC 6 of a recorded information at the time when the signal quality is determined to deteriorate by a reference signal quality determination section 27. The HDC 6 reproduces information in a corresponding recording regino on a recording medium 3 by the magnetic head 1 to perform re-recording, thereby preventing deterioration of signals.
