Title: Method for recording and reproducing magneto-optical information
Inventor: TOYOSHIMA TAKASHI
IPC: G11B11/10
Filed: 1990-05-09
Abstract: PURPOSE:To prevent undesired forgery, erasure or reproduction of a data by recording information relating to data protection onto a medium, allowing the drive itself to recognize the information to apply recording/erasure and reproduction. CONSTITUTION:A system ID4 is recorded to an access management table area 3 and a management data is recorded corresponding to each logic sector, and revision of the management data corresponding to each logic sector in the access management table area 3 is inhibited by a command other than an access enable/inhibit command from a host computer of a prescribed system having the system ID4. Thus, when a magneto-optical disk 1 is used by a system other than the prescribed system, the recording/erasure and reproduction is controlled by the management data corresponding to each logic sector of the access man agement table area 3. Thus, the undesired forgery, erasure or reproduction of the data is prevented.

Title: Flange for cooling element
Inventor: NAKANO RIKIZO
IPC: H01L23/04
Filed: 1987-05-14
Abstract: PURPOSE:To prevent cracks due to stress caused by a difference in thermal expansion, by securing the rear face of a substrate to supporting plates arranged in a holder so that the mounting surface of the holder is abutted against the mounting surface of a sealing plate. CONSTITUTION:The principal surface of a substrate 1 on which LSi's 2 are packaged is joined closely to the sealing surface 13-3 of a sealing plate 13 by means of silver solder. The substrate 1 is fitted loosely in a rectangular hole 14-1 of a holder 14 and the rear face of the substrate 1 is fixed to supporting plates 14-3 of the holder 14 also by means of silver solder. Thereby, the mounting surface 14-2 of the holder 14 is abutted against the mounting surface 13-2 of the sealing plate 13. The mounting surface 13-2 is abutted against the end face of a cooling vessel 5 through an O-ring 6 and the mounting surface 14-2 is clampled to the vessel 5 by means of screws. The LSi's 2 will generate heat to cause thermal expansion of the substrate 1, the sealing plate 13 and the fitting 14, and stress is generated by a difference between the substrate 1 and the sealing plate 13 or the holder 14 but such stress is absorbed by a stress absorbing section 3-2 and the holding plates 14-3. Accordingly, the substrate can be prevented from being cracked by stress due to a difference in thermal expansion.
