Title: Controlling method for generation of virtual index for magnetic disc device
Inventor: KAWAMOTO MASAKAZU
IPC: G11B20/18
Filed: 1981-05-29
Abstract: PURPOSE:To easily check all the areas for a specific track, by providing an index switching circuit so that the track capacity is managed with a virtual index in case of simulation and all the areas of the track can be used as required. CONSTITUTION:Normally a reset signal is given from a decoder circuit 9 and a signal of ''1'' is given to an AND circuit 13. Thus, a virtual index is given to a controller 10. When a specific track is desired to be checked, a specific signal is produced from a program of the device 10, the decoder 9 gives a set signal to an FF11 to transmit ''1'' to an AND circuit 12 and ''0'' to an AND circuit 13. Thus, the transmission of the virtual index signal is suppressed and the index produced from a servo pulse circuit 4 can be transmitted to the controller 10. In performing write/read to a track to be checked, since no index is generated, all the areas of track can be checked.

IPC: H01L21/02
Filed: 1993-04-08
Abstract: PURPOSE:To provide a manufacturing method of a semiconductor element wherein SOI structure having excellent crystallinity can be obtained by a simple process. CONSTITUTION:An SiO2 film 2 of about 1mum in thickness is formed on a single- crystal Si substrate 1 by a thermal oxidation method. Further by a CVD method, an amorphous Si film 3 as non-crystalline Si is formed. The a-Si film 3 on the surface side of the single-crystal Si substrate 1 is brought into contact with an Si substratum 11, and heat treatment is performed for 2 hours at 1100 deg.C in a nitrogen atmosphere. Thereby the a-Si film 3 is turned into a single-crystal film by solid phase growth wherein the surface of the Si substratum 11 acts as seeds, and complete adhesion is obtained. After that, the single-crystal Si substrate 1 is turned into a thin film by a polishing method, and a desired thin film is obtained.
