Title: Method and device for loop delay control
Inventor: KURANO TAKANORI
IPC: H04L12/42
Filed: 1989-06-29
Abstract: PURPOSE:To give a minimum loop delay without disregarding the time sequence of a reception data with respect to a packet exchange cell by reading a packet exchange cell with the closest transmission frame from a storage means sequentially after a specific number of packet exchange cells are stored in the storage means. CONSTITUTION:A line exchange cell C and a packet exchange cell P are written in separate memory areas and the line exchange cells G are read in the order of being written from the head cell of a transmission frame 12. while the packet exchange cell P are read from a cell written precedingly by a prescribed number to the cell written just before the readout. The prescribed number is a number depending on a phase difference between a reception frame 11 and a transmission frame 12 in a master node and the arrangement of the line exchange cells and the packet exchange cells. Thus, even when the line exchange cells and the packet exchange cells are arranged in the frame irregularly, the loop delay to the packet exchange cells P is minimized without causing discrepancy in the continuity of the reception data.

Then the processing liquid which flows in the electrophoresis chamber 70 once repeatedly is applied with a DC electric field generated between electrodes 110 and 111. Then the target body is separated partially with the DC electric field and moved to separation receiving liquid through a separation film 30.

Title: Magnetic recording and reproducing device
Inventor: YAMASHITA NORIYUKI
IPC: G11B5/027
Filed: 1981-10-19
Abstract: PURPOSE:To obtain nearly uniform picture quality or hues by making tape running speed of cue operation and review operation higher than a tape speed of normal reproduction by specific magnification. CONSTITUTION:In a magnetic recording and reproducing device which performs recording to a magnetic tape so that substantially adjacent recording tracks shifts in horizontal synchronizing signal recording position from each other during signal reproduction, the running tape speed of the tape 6 during high- speed reproduction wherein the tape running direction of normal reproduction and the turning direction of a drum are coincident is (4n-1)-fold as high as that during normal reproduction, and that in high-speed reverse reproduction is (4m-3)-fold as high as that in normal reproduction.

Title: Information recording medium, and reproducing method and reproducer therefor
Inventor: MIYAGAWA AKIKO
IPC: G11B11/10
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording medium, a reproducing method and a reproducer making information recorded on a medium not erroneously erased even when the medium temp. and ambient temp. change. SOLUTION: A controller 3 reads out the allowable maximum intensity value of a reproducing light preliminarily recorded on an information recording medium 1 by demodulating the signal of a photodetector 26. When the calculated intensity of an optimum reproducing light is smaller than the maximum intensity value, the controller 3 controls a laser driving circuit 4 so that the intensity of the reproducing light becomes the intensity of the optimum reproducing light. Moreover, when the intensity of the optimum reproducing light is larger than the maximum intensity value, the controller 3 sets the intensity of the reproducing light to the maximum intensity value. As a result, since the intensity of the reproduicing light is always suppressed not to be larger than the maximum intensity, even when the medium temp. and the ambient temp. are raised. the temp. of the medium 1 in a reproducing spot is never excessively raised and it is eliminated that the information recorded on the medium 1 are erroneously erased.

Abstract: PURPOSE:To enable two kinds of paper feeding operations to be arbitrarily selected according to a use mode and enhance utility of the device, by a system wherein it is selected by a switch whether paper feeding is to be conducted individually for each of a plurality of paper-feeding commands, which are continuously fed, or to be conducted collectively for the commands. CONSTITUTION:When paper-feeding commands are received by a controlling circuit 1 through an external interface circuit 2, the status of a switch 6 is read through an IO port 3. When the switch 6 is set to the side of a terminal (a), the circuit 1 outputs a paper-feeding command for feeding the paper by a predetermined amount to a paper-feeding motor driving circuit 5 each time it receives one paper-feeding command.

Filed: 1985-07-26
Abstract: PURPOSE:To improve resistance to corrosion and oxidation without using a protective film by forming a thin magnetic metallic film into which the oxide of a rate earth metal is incorporated at 0.1-10wt% on a substrate. CONSTITUTION:A magnetic recording medium 40 is constituted by forming the thin magnetic metallic film 20 into which the oxide of the rate earth metal is incorporated at 0.1-10wt% on the substrate 1 in tight contact therewith. A nonmagnetic material which excels in heat resistance and dimensional stability and has high tensile strength is preferable for the substrate 1; for example, polyester, ceramics, etc. are usable for said substrate. A ferromagnetic metal such as, for example, Co-Ni or Co-Cr alloy can be adopted for the magnetic material to constitute the thin magnetic metallic film 20. The amt. of the magnetic metal in the thin magnetic metallic film 20 is relatively decreased and the coercive force of the film 20 is more deteriorated when the content ratio of the oxide of the rare earth metal exceeds 10wt%. On the other hand, the effect of improving the resistance to corrosion and oxidation is substantially lost at <0.1wt%.

Title: Smelting furnace and raw-material supplying method thereto
Inventor: SAKAI AKIRA
IPC: G21F9/16
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of damage in a raw-material supplying pipe by connecting a raw-material supplying means to a molten metal tack and arranging separately from a molten metal tank side. SOLUTION: A raw-material supplying means 10 is arranged in connection with a molten metal phase M formed in a molten metal tank 2 and provided in isolated state from the metal tank 2 side. With the supplying means 10, shaped solid material such as metal debris is thrown in a throat part 14 from a raw-material supply inlet 12 of a material supply system 11 via a material supplying pipe 3. At the moment, if the smelting furnace is in operation, a metal phase M is formed in the metal tank 2 and part of the flows in the throat part 14 owing to siphon phenomenon. Thus, the shaped solid material is directly supplied in the metal phase M to be molten state and merges in the metal phase M in the metal tank 2 with the increase of the molten metal amount.  A molten metal extraction tank 31 accumulates this and the iron component in the molten metal is reduced by the supply 24 of gas so as to raise the extraction of other metal component and the components are unified. By this, the supplying pipe 3 is not needed to dip on the metal phase M and so the occurrence of damage can be reduced.
