Title: Seek operation control circuit
Inventor: KOUNO KEIICHI
IPC: G11B21/10
Filed: 1983-11-30
Abstract: PURPOSE:To form a seek operation control circuit capable of stable seek operation, by generating plural reference speeds corresponding to variance of a difference quantity and making always the speed constant for rushing into a position drive area. CONSTITUTION:Discriminating circuits 3-5 are not operated if the difference information quantity is large, and the discriminating circuit 3 is operated if the difference information quantity is middle or less, and discriminating circuits 3 and 4 are operated if the difference information quantity is small (larger) or less, and discriminating circuits 3-5 are operated if the difference input is small (smaller) or less. Since control of an actual speed based on reference speeds corresponding to variance of the difference information quantity is possible by plural generated reference speeds (s), the circuit can control the speed so that the actual speed for rushing into a position drive area (a) is always certain speed.

Title: Magnetic migration display panel
Inventor: TAZAKI HIROSHI
IPC: G09F9/37
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a stabilized, sharp display of writing lines at all times by using dispersion liquid in which a dispersion medium is an organic solvent and a densifying agent is fatty acid bisamide having hydroxyl with the melting point of specified value and providing the yield value in the dispersion liquid. SOLUTION: The structure of a network formed in dispersion liquid by a densifying agent is accelerated by heating, and when the temperature is close to the melting point, particles in the densifying agent are swollen and bulkly to control the movement of magnetic particles more than required and generate a dangerous state in which recording and erasing cannot be carried out. On the other hand, the densifying agent is swollen and dispersed in a solvent to form a colloid gel structure and the effect is demonstrated, and the state in which the melting point is too high is not preferable from the viewpoints of safety and processability. Therefore, fatty acid bisamide having a hydroxyl and also having the melting point of approximately 120 deg.C-160 deg.C is used as the densifying agent.  As the dispersion medium, a nonpolar solvent such as oils or aliphatic hydrocarbon and a polar solvent such as glycols or alcohols are used.

Filed: 1990-08-27
Abstract: PURPOSE:To reduce plastic waste in volume so as to facilitate its storage and transportation by providing a waste receiving container, a waste heating means and a means for applying pressure to the waste under the influence of gravity while heating the same. CONSTITUTION:The plastic waste 7a such as the packaging material for perishable foods and the bottle for refreshing beverage is placed into a container 1. A weight 4a is placed on this waste so that its projections 6 contact the waste and a lid 2 is then placed thereon. A heater 3 is energized to raise the temp. of the waste 7a in the container 1. When the inner temp. of the container reaches about 150 deg.C, most of the plastic waste such as polyethylene, polypropylene and polystyrene is molten and reduced in volume. At this time, since the weight 4a bears on the waste, the waste 7a is gradually deformed under its weight, the weight 4a is finally moved down to a position 4b, the waste 7a is formed into a condition 7b and its volume is reduced to about 1/10 of its original one.

Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To enhance temperature detection performance and improve temperature control performance by using a temperature detection element bonding- processed for a lead part to come into intimate contact with upward side of a table top. SOLUTION: A cooking container 1 is crossed in a high-frequency magnetic field that a heating coil 3 generates, whereby the container 1 is induction-heated and charged, cooking of cooks is advanced.

Filed: 1989-08-31
Abstract: PURPOSE:To enhance the accuracy of diagnosis by extracting the contour line image at every threshold value of an RI distribution image and judging the deviation of an RI integrated state from the moving quantity of the center of gravity of a contour line. CONSTITUTION:A CPU 4 collects an RI distribution image by the detection from a gamma camera 1 to write the same in a collected image memory 5. This image is subjected to smoothing processing to be written in a smoothed image memory 6. The max. density value calculated by comparing the density values of respective pixels is divided at every preset percentage to set a threshold value. A binary image at every threshold value is extracted with respect to the image of the memory 6 and a contour line at every threshold value is calculated by performing the tracking of the boundary line of the binary image to be stored in a contour line image memory 7. Center-of gravity coordinates data at every figure surrounded by the contour lines is calculated from the contour lines according to a predetermined formula and the relation between the data and the threshold value is stored in an RAM 9. From this data, the moving quantity and direction of the center of gravity between figures are calculated and the deviation of an RI integrated state is known therefrom.

Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce a message communication amount between both entities by reporting only the change amount of a result to a high-order entity by an execution entity at the time of executing carrier sensing in a base station system. SOLUTION: The high-order entity 1 reports all carrier numbers for performing carrier sensing and carrier sensing start to a low-order entity 2. The low-order entity 2 stores the carrier sensed results of all channels (the respective carriers of respective slots) in an internal memory and reports them to the high-order entity 1 at the point of time when the carrier sensing of all the channels is ended. The high-order entity 1 stores reported results as resource management data. The low-order entity 2 continues the carrier sensing thereafter as well and reports only the changed carrier sensing level (new result) of the channel to the high-order entity 1 only when change exceeding a threshold value set beforehand is generated in the result of carrier sensing. The high-order entity 1 updates the resource management data only for the new result.
