摘要： PURPOSE:To improve the jitter margin. CONSTITUTION:In such a format that pits in an outer circumferential part of a disk become smaller in size against a rotary angle, e.g. a CAD format, etc., even when the pulse width indicating the existence of pit data of a pit data detecting signal to be outputted from an optical sensor in the outer circumferential part of the disk is narrowed, the pulse width indicating the existence of pit data of a binary signal obtained by binarizing the above signal should not be narrowed. The subject circuit is provided with a binary deciding value generating circuit 20 for making the size of a deciding value signal S4 indicating the existence of pit data smaller when the optical sensor 2 in a track position is in the outer circumferential part of the disk 1 than when it is in an inner circumferential part of the disk 1. Then, the binary signal S5 is obtained from a pit data detecting signal S2 by a binarization circuit 11 using this deciding value signal S4.

摘要： PURPOSE:To detect the abnormality of lift-off by obtaining the difference between the transmission time for preliminarily determined proper lift-of and that for measurement and the difference between the transmitted wave peak value for said lift-off and that for measurement in a molten metal solidified state detector using a transverse ultrasonic wave. CONSTITUTION:An ultrasonic transmitter 20 is arranged in one side of an ingot 16, and a receiver 22 is arranged in the other side. A current is supplied to the transmitter 20 from a magnetic field exciting circuit 24, and a pulse current is supplied from a transmission pulse generator 26. Next, the ultrasonic wave is received by the receiver 22 and is inputted to a signal processing circuit 30. The transmitted wave peak and the transmission time due to a timing control unit 28 or the like are calculated by the circuit 30. A transmitted wave peak height corresponding to the transmission time for proper lift-off (the distance between the transmitter 20 or the receiver 22 and the ingot) is preliminarily determined by the circuit 30, and the difference between this height and the transmitted wave peak height for measurement is obtained to detect whether lift-off is too long or short. Consequently, lift-off is set to a proper value to accurately detect the solidified state of the molten metal.

摘要： PURPOSE:To improve the determination accuracy of fluorescence X-ray analysis by fetching a shield coefficient and finding the function system of four X-ray intensity, element content, sticking amount, and thickness logically. CONSTITUTION:Detectors 32 and 36 detect the intensity of a secondary X ray generated by a Cu film 14 and a Zn film 16 on, for example, an Fe base material 12 to obtain integral intensity values Ic and Iz. Then specific data, said Ic and Iz, and Cu content Pc' selected temporarily are used and the 1st calculated value sigma1' of the shield coefficient of Cu and the sticking amount Mcz' are calculated from a logical expression. Then, the Mcz', Pc', etc., are used to calculate film thickness delta1' and further the 2nd calculated value sigma2' of the shield coefficient of Cu is calculated from, for example, a regressive expression. Then the Pc' is selected repeatedly until the difference between the sigma1' and sigma2' is coincident within desired accuracy and the Pc', Mcz', and delta' when the both coincide with each other are found respectively and determined as the element content, sticking amount, and thickness at the same time.

摘要： PURPOSE:To uniformize thickness of a strip and to improve the surface characteristic by measuring molten metal quantity in a tundish by on-line and PID- controlling position of the stopper rod based on deviation of measured value to the aimed value. CONSTITUTION:At the time of casting the strip 28 by supplying the molten metal 10 from molten metal holding device 16 through the tundish 12, the molten metal quantity in the tundish is measured by the on-line. The position of the stopper rod 14 is PID-controlled based on the deviation of the measured value to the aimed value. By this method, the thickness of the strip is uniformized and the surface characteristic is improved.

摘要： PURPOSE:To provide an external storage which quickly reflects an access state from a host and improves the access performance by updating an access frequency table in order of earlier sequences of an access sequence table and reflecting this updating result on the frequency data. CONSTITUTION:The addresses recorded on an access sequence table 16 are checked and a data cache device is processed based on the address check results. Then the access frequency is checked for all data. As a set type optical disk device 20 usually has an extremely large quantity of data, a host 50 has an access to just several percents of all data in many access. Therefore the access frequency check is preferentially given to the part that received an access from the host 50. Thus the access state can be quickly reflected on the rationalization of access frequency. As a result, the mean access time including the exchange of optical disks can be shortened and also the access state can be quickly reflected on the cache state from the host 50.

摘要： PURPOSE:To attain fault processing of an optical disk without applying any load to a host by sending the abnormal optical disk to an optical disk access device and transferring the data sent to a data cache device to a reserved optical disk device. CONSTITUTION:When it is decided that an optical disk is abnormal, a request is given to a sending mechanism 36 to send the abnormal disk to an optical disk access device 18. Then the data stored in the abnormal disk are sent to a data cache device 16 from the device 18. At the same time, the data under transfer are registered in an address table 30. When all data of the abnormal disk are sent to the device 16, a controller 12 gives a request to the mechanism 36 to return the abnormal disk to a storing shelf 34. Then the position of the abnormal disk is exchanged with the position of the shelf 34 of a reserved optical disk.

摘要： PURPOSE:To prevent the deposit of a stopper rod by measuring the molten metal amt. or its varying speed by on-line, controlling the position or moving speed of the stopper rod based on the deviation in this measuring value and target value and regulating the position of the stopper rod under specified conditions. CONSTITUTION:The stopper rod 14 controlling the feeding amt. of a molten metal 10 to a tundish 12 is provided on a melting furnace 16 and a stopper rod driving device 18 like a DC servomotor is fitted thereto. The molten metal weight is measured by fitting a load cell 12 to the tundish 12 and in case of casting the position of the stopper rod 14 is subjected to PID controlling by a control device 24 so as to attain to the weight corresponding to the tundish inner molten metal level. In case of the opening of the stopper rod 14 being reduced there is a possibility of deposition the stopper rod 14 and a stopper seat 16A, so the deposition of the stopper rod is evaded by providing the lower limit value dmin by the conditions of the equation dmin>=50/(rho.C.DELTAT.h) on the stopper opening. In the equation, the rho is the density of molten metal (g/cm ), C is the specific heat of the molten metal (cal/g), DELTAT is the difference in the molten metal temp. and its m.p. ( deg.C) (10

摘要： PURPOSE:To improve production yield of a cast slab by controlling casting velocity based on perfectly solidified assuming position found from ultrasonic propagation delay time with ultrasonic transceivers arranging at position, where the aimed perfectly solidified position in the cast slab is sandwiched, and also at the downstream side thereof. CONSTITUTION:The ultrasonic transceivers 1-3 are respectively arranged at the position, where the aimed perfectly solidified position in the cast slab 4 is sandwiched, and also at the downstream side thereof. The perfectly solidified position is found from the ultrasonic propagation delay times with these ultrasonic transceivers 1-3 and by this, casting velocity is controlled, and the perfectly solidified position is controlled so as to coincide with the aimed position. By this method, the production yield is improved.
