Title: Method and device for displaying target
Inventor: YAMAGUCHI YASUKO
IPC: G01S13/66
Filed: 1989-02-10
Abstract: PURPOSE:To display the coast state of target signal on a display screen by deciding whether a tracked target is in a coast state or not and blinking a target marker when so. CONSTITUTION:A target information display device 5 which displays a target marker corresponding to a video signal on a video display device 10 by illumination. A clock 12 sends a clock signal 15 with a period T. Assuming that a cost stage is indicated when a coast signal is 1, the clock signal 15 is validated by a NAND circuit 13 when the tracked target is in the coast state and the clock signal is invalidated when the tracked target is not in the coast state. When the tracked target is in the coast state, an AND circuit 14 turns on the target marker by a target marker illumination device 11 if a blink display signal 16 is 1, but turns off the target marker if 0; and this operation is repeated, so the target marker blinks at a T-second period. When the tracked target is not in the coast state, the target marker still illuminates.

IPC: H02P23/18
Filed: 1984-02-22
Abstract: PURPOSE:To improve the stability of a system by unifying the feedback loop of a motor current of an AC motor to an analog signal. CONSTITUTION:An R-phase detecting current IR is fed back to between a sample- holding circuit 3 and an amplifier 5, and a T-phase detecting current IT is fed back to between a sample-holding circuit 4 and an amplifier 7.

Title: Operating method of sinter machine
Inventor: KOKUBU HARUO
IPC: C22B1/20
Filed: 1982-03-01
Abstract: PURPOSE:To stabilize the quality of sintered ores adequately in a sinter machine belonging to Dwight-Lloyd type, by controlling the operation thereof in accordance with the min. wind velocity position of the distributions of the suction wind velocities in the longitudinal direction and pallet speeds. CONSTITUTION:Powdery ores are packed continuously at desired density on pallets which are transferred continuously in the longitudinal direction with a conveyor. The pallets are conducted into an ignition furnace and during the passage therein, the ores are fired. Suction wind is passed through the fired powdery ores from above to below and while the ores are transferred, the front line of combustin is advanced from the upper to lower layers so that the ores are sintered successively. The velocity of suction wind in this case changes in the state of the sintered layers and has the characteristic that the velocity exhibits a min. value in the position of a distance L from the firing point O as shown in the figure. The distance L is determined and the value L/PS is determined by dividing the same by a pallet speed PS. This value and a strength index SI of the sintered ores have the positive correlation as shown in the figure; therefore, if the operation is so controlled as to maintain the L/PS within a desired range, the quality of the sintered ores is stabilized.

Abstract: PURPOSE:To easily obtain the above compound having high purity in colorless state while preventing the contamination caused by the corrosion of apparatus, by reacting phenol with acetone in the presence of an acid catalyst, removing the acid catalyst from the reaction product and treating the product with a specific ion exchange resin. CONSTITUTION:Phenol and acetone are subjected to condensation reaction at a molar ratio of 4-12 in the presence of an acid catalyst such as hydrochloric acid or strongly acidic cation exchange resin at 40-100 deg.C. When the acid catalyst is hydrochloric acid, the reaction product is distilled under reduced pressure (preferably 20-200mmHg) at 90-120 deg.C to remove the acid catalyst. The obtained liquid mixture having an acid concentration of 0-2 equivalent/ TON is treated with a weakly basic ion exchange resin having pyridyl group as exchange group (e.g., KEX-212, product of Koei Chem. Ind.) preferably at 70-150 deg.C for 5-60min to prevent the decomposition in high-temperature distillation process. The objective compound useful as a raw material for polycarbonate resin, epoxy resin and engineering plastics, etc., can be easily produced by this process.

IPC: G11C11/14
Filed: 1983-03-02
Abstract: PURPOSE:To perform high-precision position detection through relatively simple constitution by providing a detection part which detects magnetic bubbles propagated through a shift part and a bubble generating means which generates at least one magnetic bubble at a desired position on the shift part. CONSTITUTION:The bubble shift part 1 is constituted by laminating two layers, i.e. conductor films 12 and 13 on a bubble material layer 11 of garnet, etc., and arraying plural holes 14 and 15 in the conductor films 12 and 13 along the propagation path of magnetic bubbles.
