Title: Stator core manufacturing machine
Inventor: MIYAJI MOTOHIRO
IPC: H02K1/12
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To manufacture a stator core with high dimensional accuracy without making any slit in a band steep plate such that a protrusion, or the like, can be formed thereon. SOLUTION: The stator core manufacturing machine comprises a large number of blocks 21 each having a work bending pin 25 to be fitted in the slot forming recess 14a of a band steel plate 14, and means for arranging the large number of blocks 21 on a ring having at least an arcuate part and moving the large number of blocks along the annular arrangement.

Title: Optical pickup device and disk recording and reproducing device utilizing the same
Inventor: KATO SEIZO
IPC: G11B7/135
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To enable a device to reproduce either of a DVD(digital versatile disk) or an ASMO(advanced storage magnetooptical disk). SOLUTION: When a disk 28 is an ASMO, a control voltage of 0 V is applied on a liquid crystal shutter 16. Therefore, the polarizing plane of a laser beam is rotated by 90 deg. by means of the liquid crystal shutter 16 and thereafter, the beam is diffracted by a polarization selective hologram 20. Consequently, three laser beams are obtained. Then, an RF signal is generated based on the three laser beams reflected by the disk 28 and tracking and focusing are controlled. When a disk 28 is a DVD, a control voltage of 5 V is applied on the liquid crystal shutter 16. Therefore, the polarizing plane of the laser beam is not rotated and the polarization selective hologram 20 does not diffract the laser beam. Consequently, only one laser beam is reflected by the disk 28, the RF signal is generated based on the laser beam and tracking and focusing are controlled.
