Title: Nozzle for continuous casting
IPC: B22D41/50
Filed: 1992-03-19
Abstract: PURPOSE:To prevent the development and the growth of solidified steel by arranging slits extended in the mold width direction on the side surfaces of a nozzle tap part at an immersion part into molten steel at the time of stationarily pouring molten metal with respect to the immersion nozzle opening a molten steel discharging hole in long length in the mold width direction at the bottom surface. CONSTITUTION:On the side surface at the tip part of the nozzle 1 immersed into molten steel near the mold surface at the time of immersion-casting, the slits 2 extended in the mold width direction are arranged over the almost whole width. During the immersion-casting, by flowing out the molten steel from the slits, the flow without stagnation on the molten steel surface is developed. By making the width of the slit 2 extended in the mold width direction set at the tip part of the nozzle 1 suitably, the flow-out of the molten steel from the slits 2 is restrained in the opening casting period from the casting start to the immersion-casting. By this method, the development and the growth of the deckle at the stagnated part in the local molten steel flow on the molten steel surface part can be prevented by the development of uniform flow. Further, direct collision of the molten steel flow to the mold is prevented, and the heat deformation and the erosion of the mold is prevented.

Title: Mode synchronized fiber ring laser
Inventor: ARATAIRA SHIN
IPC: H01S3/083
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To sharpen a pulse by a mode locker by setting the length of a ring resonator to be one which is determined by a pulse repetition frequency and central wavelength of a generated pulse strain and a mean value of the group velocity distribution of the ring resonator. SOLUTION: Optical components such as an optical fiber coupler 10, a mode locker 12, an optical isolator 14, an erbium-doped optical fiber 16, a WDM coupler 18 are connected in the shape of a ring by means of an optical fiber 20. The length of this ring resonator is set to a value which is integral number of times as long as a distance Zperi determined by a formula Zperi = 2c/(λ<2> |D|f<2> ), where 'c' is the speed of light in vacuum, λ is the central wavelength, |D| is the absolute value of the mean value of the group velocity distribution, 'f' is a pulse repetition frequency. When the length of the ring resonator is an integral number of times as long as the distance Zperi, the shift of a phase in each mode due to the group velocity distribution becomes equivalently zero.  As a result, a light pulse output from a mode locker 12 returns to the original waveform after circulating in the ring resonator and then is input into the mode locker again and thereby the pulse can be effectively sharpened by the mode locker.

Abstract: PURPOSE:To remarkably improve operatability in selecting the field of vision on a sample image display unit, by making the relation between the sample moving operation and visual movement in a sample image display device keepable constant at all times even if the direction of sample scanning by a radiated beam is rotated to some extent, in case of a charged corpuscular-ray device. CONSTITUTION:A deflecting coil 7X7Y of a cathode-ray tube 7 to be used for a scanning image display device is supplied with a scanning signal from a scanning signal circuit 3, and further given a detection signal out of a sample as a brightness modulation signal of a CRT picture so that a sample scanning image is displayed on the CRT picture. A rotation circuit 4 is supplied with a signal out of a ratation signal generating device 8 and, with this rotation signal generating device 8 operated, a sample scanning direction on top of the sample is rotated whereby the field of vision inside the CRT picture can be optionally rotated. On the other hand, in order to shift the field of vision on the CRT picture, a moving signal generating device 9, which generates the sample moving signal in both H and V directions, is operated and thereby an output signal from the moving signal generating device 9 is fed to driving circuits 11H and 11V via a central control circuit 10.

Title: Optical noise suppression method, device therefor and optical noise suppression system
Inventor: OKAZAKI HIDEYA
IPC: H04B10/294
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide the method and device stable against fluctuation of the level of an optical signal input and capable of suppressing noise amplified through amplification by converting an output level of an optical signal to a same level, and compressing only a low level component of an output optical signal so as to suppress optical noise. SOLUTION: When a signal optical pulse is given to an optical amplifier 2 through an optical fiber 3a, since the optical amplifier 2 is controlled so that its output power is made constant, the input signal optical pulse is given to a saturable absorption type optical element 1 via an optical fiber 3b. The saturable absorption type optical element 1 has a nonlinear transparent characteristic depending on the intensity of input light, which transmits a data pulse with a high light intensity in excess of the absorbing capability of the optical element and transmits a pulse with a small light intensity with attenuation because of strong absorption. Thus, the signal light received from the optical fiber 3a becomes a signal light whose optical noise is suppressed and whose S/N is enhanced and then outputted to an optical fiber 3c.

Title: Fluid pressure joint
Inventor: NAKAMURA MASAKUNI
IPC: F16D1/06
Filed: 1994-03-31
Abstract: PURPOSE:To provide the fluid pressure joint which has stress concentration at a R section reduced with the radius of an enlarging section made thicker than the thickness t of a swelling wall, can extend the life of fatigue, and can sufficiently withstand repeated pressurizing. CONSTITUTION:In this fluid joint, the radius R of an enlarging section 6 is made larger as compared with the former one, if a dimension from the end section of the enlarging section 6 to the end section of a joint main body is h, relation shall be h>R<t. By this constitution, the stress concentration coefficient of the enlarging section 6 is made low, its welding section is well finished, and a notch factor is also made low. When fluid(oil) is filled in a fluid chamber 5 with pressure, a swelling wall 4 is subjected to the bending stress, and the outer wall surface of the enlarging section 6 is subjected to the tension stress, the stress incurring areas of these two kinds are used to have been close together so far, and which thereby gives rise to high stresses because of their relative actions. The enlargement of the R of the enlarging section 6 permits the stress incurring areas of these two kinds to be parted, and also can prevent stresses from being high.
