Title: Recording medium
Inventor: YAMADA HIDEAKI
IPC: G11B7/08
Filed: 1997-10-17
Granted: 2002-05-11
Abstract: A photodetector PD81 is positioned at the predetermined position of the optical table in the recording medium of the present invention, rotation of an original resist disc 110 is stopped and a laser 73 for focusing is driven to position the recording lens with a head slider control circuit 101. The original disc 110 is rotated to actuate a focus servo circuit 103 and PD 81 is fine adjusted in the horizontal direction corresponding to the estimated proper focusing position data with a focus fine adjusting circuit 99. With the vibration due to the rotation of the original disc 110 and fine movement thereof, a differential element of the voltage signals from two output terminals of PD 81 is varied, and a differential amplifier 103a moves the recording lens 77a in several μm in the vertical direction so that an error signal becomes zero. At this time, the numerical information of the digital indicator 93 is compared with the focus position data, when both data are matched, the focusing position data is used for the initial setting of the adequate focusing position, and when both data are not matched, the numerical information is used as the proper focusing position data through rewriting. Thus, the initialization work using the numerical conversion of proper focusing position data corresponding to the kind of the original disk can be easily executed.

Title: Heat sink
Inventor: WU MING-CHANG
IPC: G06F1/20
Filed: 1998-04-03
Granted: 1999-07-01
Abstract: A kind of forming method for heat sink used for the central processing unit. The method is to extrude the material through a fan-shaped mold to get an arc-like base with fins vertical to the base. The heat sink base is then deformed from arc to straight, with the fins on the base also moving inwardly, to form the final product. By doing this, the number of fins per unit area on the heat sink increases such that a better heat dissipation can be obtained. Moreover, the mold wall between fin cavities can be thicker than that in traditional mold, therefore the mold is less prone to damage under impact.

These gases are activated as plasma at a pressure of, e.g., 0.1 Torr, to deposit a CF film on a semiconductor wafer at a process temperature of 400 DEG C using active species thereof. The decomposition products of C5F8 gas may be C5F8, C4F6, C3F4 and so forth which have double bonds, and the recombined materials thereof have a steric structure and strong bonds, which are difficult to be cut even at a high temperature, so that the degassing quantity is small. Alternatively, C6F6 gas having an annular structure is used as a thin film deposition gas, and activated as plasma at a pressure of, e.g., 0.06 Pa, to deposit a CF film on a semiconductor wafer at a process temperature of 400 DEG C using active species thereof. The decomposition products of C6F6 gas may be C6F6, C5F3, C3F3 and so forth which have double bonds, and the recombined materials thereof have a steric structure and strong bonds, which are difficult to be cut even at a high temperature, so that the degassing quantity is small.
