Title: Epitaxial wafer
Inventor: WATANABE MASAHARU
IPC: H01L21/322
Filed: 1986-10-21
Abstract: PURPOSE:To reduce a transfer density in an epitaxial layer thereby to increase the lifetime of an epitaxial layer by adhering the epitaxial layer to an N-type silicon single crystal waver of 1.2X10<18>-2.0X10<18> atoms/cm<3> of oxygen concentration having 0.1OMEGAcm or less of resistivity. CONSTITUTION:An epitaxial layer is adhered to an N-type silicon single crystal wafer of 1.2X10<18>-2.0X10<18> atoms/cm<3> of oxygen concentration having 0.1OMEGAcm of resistivity. Since a transfer then occurs in a substrate, heavy metal (Fe, Ni, Cr, etc.,) in the layer tends to be gettered. Thus, since the transfer concentration in the layer tends to decrease, the lifetime of the layer increases.

Title: Disk device
Inventor: OKAJIMA TADASHI
IPC: G11B7/007
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To enable a disk device to execute stable seek. SOLUTION: The disk device 10 includes a DSP(digital signal processor) core 36, and when a music-jumpting instruction is given to the device during playing a MO(magneto-optical) disk 42, the DSP core 36 sets a count value corresponding to the total number of lines of tracks to be jumped in a counter 34. Then, the core 36 moves an optical pickup 12 in the radial direction of the disk 42 by turning a tracking servo off. The core 36 counts down the counter 34 by detecting the rising edge and falling edge of a TZC (zero cross to be changed over to a high level/a low level with the zero cross of a tracking error signal) signal. When the count value becomes 1, the core 36 judges whether or not an offset value is fluctuated by judging the level of the TZC signal. When the offset value is fluctuated, edges are erroneously counted, and hence the core 36 increments the count value.  As a result, the optical pickup can jump to a desired land or groove. In short, the pickup can make a reliable access to the target position.

Abstract: PROBLEM TO BE SOLVED: To allow the use of an existing demodulation IC incorporated with a bit once-over circuit similarly to the recording data specification for the bank provided with null data, even in the case the data not provided with null data like the recording data specification for the post office are read out. SOLUTION: The mechanical noise is generated when a magnetic head 2 is run onto a magnetic tape 1-1. This mechanical noise is superimposed on the top of a signal to be demodulated. The position where the mechanical noise becomes the ungenerated state, is defined to the stable position P1, then the signal to be demodulated on or after the stable position P1 is given to the demodulation IC 3 through a data adding circuit 4. The bit onceover circuit 3-1 for giving once-over the top several bits (two bits in this instance) is incorporated in the demodulation IC 3, and in the case of the recording data specification for the post office not provided with the null data, the once-over is given for a part of tie recorded data when the signal to be demodulated on or after the stable position P1 is given as it is.  In the data adding circuit 4, therefore, the pseudo data in the amount of the number of bits which the once-over is given by the bit once-over circuit 3-1, are added to the top of the signal to be demodulated on or after the stable position P1 to the bit once- over circuit 3-1.
