Title: Manufacture of oxide single crystal
Inventor: YASHIRO SATAO
IPC: C30B15/00
Filed: 1981-09-08
Abstract: PURPOSE:To prepare a high quality oxide single crystal with high yield, by maintaining a seed crystal at a specified temp. in the outside of a pulling furnace before heat melting a starting material, and then, bringing it into contact with the melt in the furnace to seed it. CONSTITUTION:A seed crystal is held at the outside of a pulling furnace at <=100 deg.C until a step of heat melting a starting material has been completed in a noble metal crucible preparing a single crystal from the high temp. melt. After the temp. of the melt has been adjusted to a specified seeding temp., the seed crystal is gradually introduced into the pulling furnace to bring it into contact with the melt and to seed it, thus permitting the obtained oxide single crystal to be reduced in deterioration of quality and enhanced markedly in yield of production of high quality crystal by reducing attachment of impurities to the seed crystal. Said oxide single crystal is LiNbO3 single crystal and LiTaO3 single crystal.

Title: Track count circuit
Inventor: OGATA TOSHIHIRO
IPC: G11B21/08
Filed: 1990-05-30
Abstract: PURPOSE:To prevent the undetection or the erroneous detection of a track count by turning the generation timing of a track count detection gate signal to the optimum value by a velocity signal at present and an acceleration signal. CONSTITUTION:A velocity detection means 15 detecting the present velocity from a track binary signal 1, an acceleration indication means 17 indicating the present acceleration, and a wind control means 11 generating a track count detection gate pulse form the outputs of the velocity dection means 15 and the acceleration indication means 17, are provided. The arriving track binary signal 1 outputs the rise or the fall of the binary signal 1 as a track count signal 4 by a track count detection means 18 only during the track count detection signal 2 is 'active'. Namely, timing between the next track binary signal 1 and a track count detection gate signal 2 is not deviated even at the time of acceleration-deceleration. Thus, the undetection or the erroneous detection of the track count can be prevented.

Title: Magnetic recording medium
Inventor: OSABE KUNIJI
IPC: G11B5/702
Filed: 1983-08-02
Abstract: PURPOSE:To obtain a magnetic recording medium which prevents effectively seizure of a magnetic layer to a magnetic head while maintaining the physical characteristic of the magnetic layer by compounding specific unsatd. sulfide with the magnetic layer consisting of ferromagnetic metallic powder dispersed in a binder. CONSTITUTION:A magnetic coating prepd. by compounding the unsatd. disulfide expressed by the formula at 0.5-10pts.wt. to 100pts.wt. ferromagnetic powder is coated on the surface of a nonmagnetic base to form a magnetic layer. The S in the unsatd. sulfide prevents seizure of the magnetic layer to a magnetic head by forming the sulfide layer on the surface of the ferromagnetic metallic powder and acts also as a lubricant. Therefore a good result is obtd. in the case of using said sulfide in combination with a lubricant if the sum of the disulfide and the lubricant is kept at <=10pts.wt. with respect to 100pts.wt. the magnetic powder. The magnetic recording medium having an excellent still characteristic, durability, etc. is thus obtd.

Title: Ternary signal device and method therefor
Inventor: GARNETT PAUL JEFFREY
IPC: H03K19/20
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide improvement for providing many options or extended ternary encoding by performing the extended ternary decoding of a ternary input signal in response to the output signal from a window comparator output in both phases. SOLUTION: When a pin 12 has a low value L, the outputs B and A of 1st and 2nd comparators 16 and 18 have low values L, which are encoded by an encoder 24, so that an output X has a high value H and outputs Y and Z have low values L. Similarly, when the pin 12 has an intermediate value M, the outputs B and A have low and high values L and H, which are encoded by the encoder 24, so that the output Y has a high value H and the outputs X and Z have low values L. When the pin 12 has a high value H, on the other hand, the outputs B and A have high values H, which are encoded, so that the output Z has a high value H and the outputs X and Y have low values L. When the pin is open, resistances R1 and R2, and R3 to R5 for forcibly setting the pin to an intermediate value M are set equally to supply a reference voltage to the comparators 16 and 18.

Title: Magnetic recording and reproducing device
Inventor: OSUE TADASHI
IPC: H04N5/922
Filed: 1984-07-06
Abstract: PURPOSE:To prevent lowering of high band of a broad-band signal by selecting carrier frequency of an FM modulated signal larger than a value near the frequency corresponding to the peak, and at the same time, providing an emphasis circuit in the front stage of an FM modulator and providing a detector that detects rotational frequency of a magnetic disk. CONSTITUTION:FM modulated video signals reproduced by a magnetic head 9 are amplified by a regenerated amplifier 12 and supplied to an FM demodulator 14 through a change-over switch 13, and original video signals are outputted in an outut terminal 15. A detector 11 detects rotational frequency of the disk 10 acording to the position of a driving device 9A on the radius of the disk 10, and controls and varies carrier frequency of the FM modulator 6 and FM demodulator 14. When the frequency characteristic and the band of video signals supplied to an input terminal 3 is as shown by a curve 18, if an emphasis circuit 4 is set to be augmented at above frequency fc-fm, frequency spectrum of FM modulated video signals in the case where the emphasis circuit is not provided becomes flat as shown by a curve 22. Thus, the possibility of deterioration of high band of reproduced video signals obtained by FM modulating video signals, recording in a magnetic disk that rotates at a fixed linear speed, and FM demodulating can be eliminated.

Filed: 1989-06-05
Abstract: PURPOSE:To accurately determine a crack by correcting the data obtained by an NaI detector on the basis of Bi/K calculated by a Ge detector to calculate more accurate Bi/K distribution and further together using an underground radar method. CONSTITUTION:A wide range of many measuring points are measured within a short time while an NaI detector is moved and the intensities of gamma-rays corresponding to the gamma-ray energies inherent to Bi-214 and K-40 are calculated to calculate a Bi/K ratio and the positioning of a point having a high Bi/K ratio is performed. Subsequently, the absolute value of the intensity of gamma-rays at the specified high Bi/K position is measured by a Ge detector high in the resolving power of gamma-ray energy and having good linearity. Then, the energy correction of Bi or K is performed from the data of the NaI detector on the basis of the Bi/K ratio calculated by the Ge detector and more accurate Bi/K distribution is calculated. Further, the relation between the outline structure of a shallow underground stratum read from the fault image of the ground due to an underground radar method and the high Bi/K position and a geological mechanism generating radon are investigated and, by synthesizing these results, the position of a crack can be determined accurately.
