Patent JP-H03297531-A (JP)
Title: Forging method
Inventor: ISOGAWA YUKIHIRO
IPC: B21J3/00
Filed: 1990-04-13
Abstract: PURPOSE:To forge hard-to-work material and to prolong the life of a die, etc., by sticking lubricant melted by heating on a cut surface to be forged in a forging device before it is forged. CONSTITUTION:In the device 1, film formation and lubrication are executed to a sectional surface to be forged before it is forged. In that case, hot-melt lubricant 20 is stuck by coating, spraying, dipping or pressing, etc., to form films 20a, 20c. When the steel material 3 itself is not heated at all, these films remain to be melted. Since the lubricant itself is melted by heating, the steel 3 itself need not always be heated at a specified temperature. Consequently, the side of the steel material 3 is desired to be heated in accordance with the working temperature and graphite lubricant refrains necessary heat dissipation as a result, it need not be held at a high preliminary heating.

Title: Semiconductor laser module
Inventor: MORIMOTO YUKIHIRO
IPC: H01S5/00
Filed: 1982-06-08
Abstract: PURPOSE:To prevent a noise originating from a high frequency component by coupling a semiconductor laser with a multimode fiber through a mode mixing part. CONSTITUTION:Projected light from the semiconductor laser having divergence is collimated by a distributed index lens 5 to below the numerical aperture of the multimode fiber 4 and then guided to a multimode fiber 4 through a multimode fiber 6 with bending structure. In this case, numbers of modes are energized by the multimode fiber 6. Consequently, mode intensity with a coefficient etam of mode coupling is dispersed to a mode with a small coefficient etam of mode coupling, so a coefficient -eta of coupling is made less than that of a conventional semiconductor laser module. Thus, the noise originating from the high frequency component is prevented.

Title: Device for passing fuel fluid in magnetic field
Inventor: OHARA SHIZUKI
IPC: F23K5/08
Filed: 1990-04-13
Abstract: PURPOSE:To improve fluidity of fuel oil and at the same time elongate a time during which a physical-chemical action is applied to the fuel oil by a method wherein annular magnets are spaced apart so as to cause their same poles to be faced to each other, outer walls and inner walls of non-magnetic material are disposed at a centrifugal side and an inner side of the spacings so as to form annular passages for the fuel fluid. CONSTITUTION:Fuel fluid F fed from a main feeding port 19 at first reaches a feeding part C at a lower part of an inner cylinder 8, is dispersed from a through-pass hole 18 formed at the inner cylinder 8 in a circumferential direction, discharged and then the fuel fluid reaches an outer circumferential flow passage A. Then, the fuel fluid passes through a filter 13, passes through a feeding port 16 of an outer cylinder 9 and enters each of annular passages 10. After passing around by about 3/4 in the passages 10 in a clockwise direction, the fuel fluid passes through a discharging port 17 of the inner cylinder 8 and reaches each of inner circumferential flow passages B, where the flows are merged and then the fluid is discharged out of a main discharging port 20. Since the fuel fluid circulates around the passages 10 in a magnetic field spacing where the same magnetic poles are opposed to each other, the fuel fluid F is exposed in the magnetic field spacing for a long period of time. A flow passage configuration except the annular passages 10 is made simple, resulting in a relative low passage resistance.

Abstract: PROBLEM TO BE SOLVED: To detect landslide without being affected by installation condition of an optical fiber or temperature change by calculation for correcting the distortion value of a temperature change component for the distortion value of a distortion-detecting optical fiber, thus calculating a true distortion value. SOLUTION: A distortion-detecting optical fiber 10 and a temperature-detecting optical fiber 11 are installed on a slope 1 and a slope upper part 2 where the landslide may occur. An optical switch 3 switches between the distortion-detecting optical fiber 10 and the temperature-detecting optical fiber 11, alternately, according to the control signal outputted from a signal processor 5. A distortion distribution measuring device 4 measures distortion-distribution of the corresponding optical fiber 10 or 11, and transmits a measuring result to the signal processor 5.  At a correcting/calculating part 52, the distortion value indicated by a distortion-distribution measuring result 50 is offset by the distortion value which changes under the effect of the temperature indicated by a distortion-distribution measuring result 51 to calculate a direct distortion value at the distortion-detecting optical fiber 10, which is outputted to a comparison circuit 53 and a data recording part 57. The comparison circuit 53 ignores presence of distortion, and when a distortion which exceeds a specified value is detected, an alert 56 is outputted from an alarm 55.

Title: Storage device
Inventor: TAKANASHI SHUICHI
IPC: G06F12/16
Filed: 1989-04-20
Abstract: PURPOSE:To prevent an error correcting function from being lost even if a fault occurs in one side of error bit pointing out means by providing two first and second sets consisting of respectively of the error bit pointing out means and an error detecting means constituted of a storage element, and inputting the outputs of the first and the second error bit pointing out means to each other. CONSTITUTION:When an error occurs in the first error bit pointing out means 5, and the first error detecting means 7 detects the error, a selecting means 3 selects the contents of the second error bit pointing out means 6, and outputs them to a correcting means 4. The correcting means 4 corrects read out data from a storing means 1 in conformity to an error bit position obtained from the output of the selecting means 3, and sends corrected data (c). On the other hand, since the output from the second error bit pointing out means 6 is being inputted to the first error bit pointing out means 5, the output of the second error bit pointing out means 6 is written in the first error bit pointing out means 5 at the timing of a write pulse (a) by the output of the first error detecting means 7. Thus, even if the fault occurs in one side of the error bit pointing out means, the error correcting function is never lost.

Abstract: PURPOSE:To improve electrostatically charged developer carrying performance and carrier selectivity for particles electrostatically charged to be in a specified polarity and to stably form a vivid image for a long time by using a developer carrying member having the laminated structure of an electret dielectric layer and a protective dielectric layer on the electret layer. CONSTITUTION:The developer carrying member 1 has the laminated structure of a sleeve base body 2, the electret dielectric layer 3 on the base body 2, and the protective dielectric layer 4 on the layer 3. The layer 3 is electrostatically charged to have the charge of a certain polarity, for instance, to be positive body polarization, and the one-component non-magnetic developer 9 is electrostatically charged to have the charge of the reverse polarity to the surface charge of the electret, that is, to be negative in such a case. An electrostatic latent image supporting body 7 has an electrostatic latent image D electrostatically charged to be in the reverse polarity(positive) to the developer particles and a non-latent image part L on its surface. By providing the protective dielectric layer 4 on the electret layer 3, the lowering of the surface potential Edelta of the non-latent image part is restrained to negligible order, and the occurrence of surface fogging is prevented for a long time. Thus, the carrying performance for the electrostatically charged powder developer and the selectivity of the electrostatic charging polarity are stabilized, thereby maintaining the device at an excellent level.
