Title: Measuring method for water level
Inventor: MORIKAWA KIMIO
IPC: G01S13/34
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To enable precise water-level calculation by finding the distance from an antenna to a water surface by a specified formula, from the frequency of a beat signal extracted by a discrete Fourier transformation processing, using the principal frequency component of the beat signal. SOLUTION: A frequency-modulated transmitted wave 10 from a transmitting unit 1 is radiated to the water surface 9 of a well 8 through a circulator 2 and an antenna 3, and its reflected wave 11 is inputted into a receiving unit 4 through the circulator 2. Besides, the receiving unit 4 receives a part of the transmitted wave 10 through the circulator 2, and detects a beat signal generated by mixture of a part of the transmitted wave 10 and the reflected wave 11. The distance R from the antenna to the water surface is found, by substituting into a formula the frequency fn value of the beat signal obtained by giving an optimum beat frequency value found beforehand from a water level data by inverse operation to the adaptive filter of a signal processing unit 5, removing noise, and performing discrete Fourier transformation processing.  In the formula, c represents the velocity of propagation of the radio, Δf the frequency deviation of frequency modulation, and fm the cycle frequency of frequency modulation, respectively.

Title: Continuous casting method
Inventor: SUZUKI MIKIO
IPC: B22D11/115
Filed: 1987-09-03
Abstract: PURPOSE:To prevent the development of surface defect and surface layer inclusion in a cast slab by arranging first and second DC magnetic field generators at center part and near upper side of end part in outer face of long side for a mold, respectively and impressing DC magnetic field to molten metal. CONSTITUTION:In near the outer face of the long side of the continuous casting mold 1, the first DC magnetic field generator 13 is arranged at the facing part to opening hole of a submerged nozzle 2 and the second DC magnetic field generator 14 is arranged at end part of the short side. At the time of pouring the molten metal into the mold 1 from the tundish submerged nozzle 2, the first magnetic field generator 13 gives the molten metal flow just after discharging from discharging holes 3 the magnetic field to reduce the flow speed. The second magnetic field generator 14 gives waving of the molten metal surface the magnetic field, to limit the waving height in the fixed range. As the waving height on the molten metal surface is limited, entrainment of mold powder into the cast slab is eliminated. By this method, the development of the surface defect and the surface layer inclusion in the cast slab are improved.

Title: Grating lens optical system
Inventor: KATO MASAYUKI
IPC: G02B5/18
Filed: 1986-09-20
Abstract: PURPOSE:To realize the wide practical use of a grating lens by providing two in-line type grating lenses with a specific frequency distribution, making two light beams which are symmetrical about on optical axis cross each other in the space between both lenses, and converging them each on one point. CONSTITUTION:A 1st in-line type grating lens 11 diffracts light with wavelength lambdaat a larger angle than light with wavelength lambda0 (lambda0<eta), and those diffracted light beams both cross the optical axis and then reach a 2nd in-line type grating lens 12. The arrival points of those light beams are on the same radius having its center on the optical axis and the distance of the light with the wavelength lambdafrom the optical axis is larger than that of the light with the wavelength lambda0. Then those light beams are diffracted by the 2nd in-line type grating lens 12, but the light with the wavelength lambda is diffracted by the larger angle than the light with the wavelength lambda0, so the interval between those light beams narrows down gradually and they cross each other at one point Q eventually. Consequently, the stable focus position which never deviates from a specific point is obtained and the practical use in various fields becomes possible.

Title: Power source for driving hysteresis motor
Inventor: ICHIKAWA KOSAKU
IPC: H02P5/74
Filed: 1986-09-22
Abstract: PURPOSE:To easily back up a hysteresis motor even when a counterelectromotive force is erased due to the defect of an inverter by exciting the motor once by a backup inverter to again generate the counterelectromotive force. CONSTITUTION:When a normal rotation inverter 20 is stopped due to a DC short-circuit defect, the terminal voltage of a hysteresis motor 10 becomes zero. Since a backup inverter 30 does not detect, even if receiving a backup command A, a rotating speed, a rotating speed detection signal D is not output. Thus, the inverter 30 is operated for a predetermined time by a one-shot timer 306 to apply a voltage to the motor 10 to excite it. Then, the inverter 30 is temporarily stopped, the rotating frequency of the motor 10 is detected by the counterelectromotive force to backup-operate it.
