Filed: 1990-11-26
Abstract: PURPOSE:To make it possible to detect fluctuations in the amount of float of a magnetic head with high accuracy and float said head in a highly stabilizing manner by using changes in an oscillating status of a semiconductor laser induced by the change in the span between a magnetic record medium and said semiconductor laser. CONSTITUTION:When an optical emitting end face is adapted to face a record medium 8 nearby and laser light reflected on the record medium is arranged to return to a semiconductor laser chip 6, the reflected light enters the laser where the oscillating condition of the laser is changed by a combined oscillating action between the semiconductor laser chip and the record medium. Therefore, the combined oscillating action between the semiconductor laser chip and the record medium is used so as to detect the changes in the span between both the laser chip and the record medium and it is also used to control the amount of float of a magnetic head 3. This construction makes it possible to float the magnetic head 3 in a highly stabilizing manner since the reflected light from the magnetic record medium is used.

Title: Mold for molding resin
Inventor: MIYAZAKI HISASHI
IPC: B29C33/44
Filed: 1993-12-17
Abstract: PURPOSE:To provide a mold for molding a resin having a slide core structure capable of performing molding without generating the damage of a protruding part becoming an undercut or the deformation of a product. CONSTITUTION:The piercing member 7 provided so as to pierce through a slide core 4 is fixed to the floating core 9 provided in the slide core 4. At the time of the start of mold opening, the slide core 4 does not immediately begin to move by the play space between an angular pin 5 and the oblique hole 15 of the slide core 4 even when a cavity 3 begins to move. However, since the floating core 9 is released from the pressing due to locking block 6, the core 9 begins to move by the energizing of a spring 10 to pull out the piercing member 7 from the hollow part of a boss 12. Since the piercing member is pulled out during a period when the slide core 4 is in contact with the side surface of a product 11 and the periphery of the boss 12, the piercing member 7 is pulled out even in a state embraced from the circumference by shrinkage without generating damage or deformation.
