Title: Hard disk emulator
Inventor: MATSUSHITA SATOSHI
IPC: G06F12/08
Filed: 1993-10-25
Abstract: PURPOSE:To quicken access just after exchanging an optical disk by previously writing access frequency data in an optical disk and allotting consecutive addresses to a cache area at the time of reloading. CONSTITUTION:When a host computer 1 accesses to a hard disk emulator 2, an emulation unit 3 obtains access frequency data and stores it in a work RAM 12. The piece of data is written in an access frequency storage area on the optical disk by back ground processing by choosing time when the host computer 1 does not access the hard disc emulator 2 at one's own direction. Then, at the time of recognizing the exchange of the optical disk, the emulation unit 3 issues a read command to the access frequency storage area of the optical disk and transfers the piece of data to work RAM 12. Furthermore, the emulation unit 3 executes the allocation of a cache area based on the piece of data.

Abstract: PURPOSE:To carry out the reaction for the production of acetic acid, acetaldehyde, etc. from synthetic gas in the presence of a Rh-based catalyst, by heating the reaction system close to the reaction temperature in the presence of an inert gas, switching the feed of the inert gas to the synthetic gas used as the raw material, and carrying out the reaction under pressure. CONSTITUTION:In the production of acetic acid, acetaldehyde and ethanol from a synthetic gas in the presence of an Rh-based catalyst, the reaction system is heated to a temperature lower than the reaction temperature by 0-100 deg.C in the presence of an inert gas, and thereafter, the reaction is carried out at 150-450 deg.C under 1-300 atm (preferably at 250-300 deg.C under 20-200 atm) after substituting the inert gas with the synthetic gas used as the raw material. The reaction can be started in an extremely short time at the prescribed reaction temperature without lowering the catalytic activity, and at the same time, the life and the selectivity of the catalyst can be improved. The reaction system is heated quickly to the prescribed reaction temperature by the generation of the heat of reaction when the feed of the inert gas is switched to the synthetic gas.

Title: Tracking controller for disk
Inventor: KUTARAGI TAKESHI
IPC: G11B21/10
Filed: 1988-10-21
Abstract: PURPOSE:To perform tracking of high precision by using two reference tracks to generate position data of an arbitrary track and oversampling position data scattered at equal angles on the track by a prescribed filter. CONSTITUTION:Reference tracks 2A and 2B where servo information is recorded are provided on the innermost periphery and the outermost periphery of a magnetic disk 1 respectively. The offset of first position data at each of points a1 to a8 and b1 to b8 of reference tracks 2A and 2B on lines extended from the center of the disk 1 at regular intervals of an angle is detected by an offset detecting means 15. With respect to the position of an arbitrary data track on the line connecting two points on the outside and the inside, second position data is obtained in DSP 11 by approximation using line interpolation. For example, eight second position data are obtained per one data track, and oversampling is performed in an FIR type digital LPF with coefficient data from a ROM 14 to obtain third position data between second data. Tracking is corrected with third position data. Consequently, position data on an arbitrary track is obtained with a high precision, and tracking of even a complicatedly deformed disk is performed with a good following-up capacity.
