Title: Automatic line fault recovery system
Inventor: ENOKIDA MIKIYA
IPC: H04L69/40
Filed: 1988-04-05
Abstract: PURPOSE:To enable a data transmission with high reliability without allowing a terminal or host to be conscious of a line fault by providing a function to automatically recover the line fault between relay systems. CONSTITUTION:When the line fault is generated while a relay system K2 receiving the transmission request of data from a processing program 2-1 of a terminal 1 through a communication line beta1 transmits the data through a communication line gamma1 to a relay system K1, the relay system K2 issues a session establishing request for establishing the communication line gamma1 to the relay system K1, and the establishment of the session is executed. The relay system K2 re-sends the data to be held without being released to the relay system K1. Thus, without allowing a terminal 2 or a host 3 to be conscious of the line fault the recovery is automatically executed by the relay system 1, and the data transmission having the high reliability can be executed.

Title: Method and device for driving magnetic head
Inventor: FUKAYA NOBURO
IPC: H02P29/00
Filed: 1988-04-07
Abstract: PURPOSE:To attain control to follow a speed setting value by calculating a speed ratio between the speed setting value of a speed setting table in a magnetic head and an equivalent real speed and executing feed-back control for a product between the speed setting value and speed ratio as a speed command. CONSTITUTION:A position signal S is outputted by the rotation of an access motor M and in each moving of one track, a pulse signal D is outputted to a timer TM. The timer TM counts the period of the pulse signal D in a suitable number and the period is outputted to a speed ratio calculating circuit RAT. The circuit RAT calculates the equivalent real speed from a track pitch and the average value of the period and the speed ratio is obtained between the speed setting value, which is sent from a storing part ROM, and the equivalent speed. Next, by a multiplying circuit MUL, the product between the speed ratio of a register RGV and the speed setting value of a register RGR is given to an adding circuit ADD as the speed command and the feed-back control is executed to a motor driving circuit MDR. Thus, a speed error, which is caused by the gain error of a speed detecting circuit and the inclination error of the position signal, is erased and the control can be executed with following the speed setting value.

Inventor: KIKUCHI YUKIO
IPC: C30B29/40
Filed: 1988-04-06
Abstract: PURPOSE:To obtain the title hardly warped wafer having a high mixing ratio of Al and a large thickness by successively growing a GaAlAs epitaxial layer having a specified mixing ratio of Al or above and a GaAlAs epitaxial layer having a specified mixing ratio of Al or below on a GaAs substrate. CONSTITUTION:A Ga1-xAlxAs epitaxial layer 1a having >=0.4 mixing ratio (x) of Al and >=100mum thickness is grown on a GaAs substrate 2a by liq. phase epitaxial growth from a soln. A Ga1-xAlxAs epitaxial layer 1b having <=0.1 mixing ratio (x) of Al is then grown on the layer 1a from the same soln. to obtain a Ga1-xAlxAs epitaxial wafer. Since the mixing ratio of Al is controlled in two steps, the warpage of the epitaxial wafer can be inhibited.

Title: Magnetic recording medium and production thereof
Inventor: NOTOHARA YASUHIRO
IPC: G11B5/738
Filed: 1989-04-03
Abstract: PURPOSE:To improve workability and productivity by mounting a spindle part to a substrate part and irradiating the surface of a magnetic film with a high- energy beam while rotating the medium around the spindle part to oxidize the magnetic film and to form the irradiated part as a nonmagnetic part, then using the part between the nonmagnetic part as a recording region. CONSTITUTION:The spindle 9 is mounted to a magnetic disk 10 and the disk is rotated around the spindle 9 by a driving means, such as motor. The laser from a light source 11 for which a semiconductor laser is used is condensed by a lens 12 onto the surface of the magnetic disk 10. The laser is projected in the atm. at this time. The magnetic film 18 irradiated with the laser is heated to a high temp. and is oxidized in a short period of time in such a manner, by which the magnetism is lost and the nonmagnetic part is formed. On the other hand, the magnetism of the part not irradiated with the laser is held as it is without being lost. The recording and reproducing of data are executed by using a part of the magnetic film 18 which is not irradiated with the laser as a track part. The track part is formed without corroding the magnetic film in such a manner and the need for mounting the spindle while registering the magnetic recording medium is eliminated. The workability is thus improved.

Title: Data reading device
Inventor: SUKIMOTO YASUYUKI
IPC: G05B9/02
Filed: 1984-04-25
Abstract: PURPOSE:To read process data after deleting the superposed noises out of the data by reading the input data having its changing width set within an allowable range of a sampling cycle after deciding it as the correct data. CONSTITUTION:A changing allowance range K is read into a RAM8 from an allowance range setting part. The process value of a control subject 1 is converted into electric signals by a sensor 2. The output of the electric signal is applied to a CPU6 of a control part 5 via an amplifier 3 and an A/D converter 4. The converter 4 is started by the signals sent from the CPU6 every time the data processing is over. The data read into the CPU6 is compared with the range K stored in the RAM8 after its changing width of a sampling cycle is calculated by the CPU6. When said changing width is within the range K, the corresponding data is read into the RAM8. Then the control amount is decided and the subject 1 is controlled via an output operation part 9. Thus it is possible to read the process data after deleting the superposed noises.

Title: Clock extracting circuit
Inventor: YASUDA HIROSHI
IPC: H03L7/10
Filed: 1987-04-07
Abstract: PURPOSE:To stably eliminate a need of adjustment by adding a frequency comparator which generates the output in accordance with the frequency difference between the reference signal and a clock. CONSTITUTION:An input digital signal passes a gate 1 and has the phase compared with that of the clock by a phase comparator 2 unless it is not dropped out, and the clock has the frequency compared with that of the reference signal by a frequency comparator 7. Respective outputs are inputted to a loop filter after being added by an adder 3, and the output is inputted as the control voltage to a VCO 5, and the oscillation output has the frequency divided by 1/2 in a frequency divider 6 to generate the clock synchronized with the digital signal. If the digital signal is dropped out, the digital signal is stopped by the gate 1 and the output of the phase comparator 2 disappears, and therefore, the clock frequency is approximately equalized to the reference frequency by the frequency control of the frequency comparator 7. Thus, adjustment is unnecessary and the capture range is stable even in case of the variation of temperature, and slip of the clock for drop-out is reduced.
