Title: Modified ethylene/alpha-olefin copolymer
Inventor: MORIGUCHI KISOO
IPC: C08J3/24
Filed: 1987-02-19
Abstract: PURPOSE:To make it possible to improve the transparency, melt tension, melt elasticity, etc., of a specified crystalline ethylele/alpha-olefin copolymer without detriment to its excellent characteristics, by moderately crosslinking it. CONSTITUTION:This modified ethylele/alpha-olefin copolymer is one obtained by moderately crosslinking (referred to as modifying hereafter) an ethylele/alpha-olefin copolymer having an ethylene component content of 75-97.4wt% an alpha-olefin component content of 2.6-25wt%, a density of 0.90g/cm<3> and a melt index <=3g/10mm. This modification is performed so that when the degree of modification is represented by (MI)2/(MI), wherein (MI)1 is the melt index before modification and (MI)2 is the melt index after modification, its value may fall within the range of 0.05-0.9. Said modification can be achieved, for example, by uniformly melt-kneading said ethylele/alpha-olefin copolymer with a radical generator such as an organic peroxide in an extruder.

Abstract: PURPOSE:To prevent a magnetic gap from being produced by a method wherein a rare-earth permanent-magnet powder is pressurized and molded in a direction perpendicular to an outside magnetic-field direction passing a cavity part inside a metal mold, a sheetlike molded body is formed and its shortest side and its weight are specified after its sintering operation. CONSTITUTION:A permanent magnet powder containing a rare-earth element is pressurized and molded in a direction perpendicular to an outside magnetic- field direction passing a cavity part inside a metal mold in order to give an anisotropic property; a one-body sheetlike molded body as a rectangular parallelepiped or whose at least one side is provided with a taper is formed. After its sintering operation, its shortest side is set to 5mm or higher and its weight is set to 500g or higher. Accordingly, a one-body rare-earth magnet of 500g or higher can be obtained without using an adhesive agent. Thereby, it is possible to obtain a large-sized and large-weight permanent magnet whose magnetic property is uniform as a whole.

Title: Picture processor
Inventor: OOTA IKUYOSHI
IPC: G06T7/00
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To more accurately judge a matching rate of shapes between optional picture areas. SOLUTION: The centroid of a picture area is calculated by a centroid calculating circuit 104 and the contour of the picture area detected by a contour detecting circuit 105 is converted into polar coordinate data around the centroid. A subtraction circuit 113 subtracts a value obtained by multiplying the mean value r1 ' of a contour function r1 (θi ) by a proportional constant (k) from the function r1 (θi ) to find out a differential function. On the other hand, a subtraction circuit 114 subtracts a value obtained by multiplying the mean value r2 ' of the other contour function r2 (θi ) to be compared by a proportional constant (k) from the function r2 (θi ) to find out a differential function.  A cosine calculating circuit 115 calculates a cosine cosz of an angle (z) formed by two differential functions and a threshold circuit 116 compares the cosine cosz with a threshold. When the cosine cosz is smaller than the threshold, a phase is shifted and similar matching rate judgement is repeated.

Abstract: PURPOSE:To improve corrosion resistance and heat resistance by covering a metallic plate with crystalline thermoplastic resin, heating and drawing it at a temperature higher than a specific temperature and redrawing it at temperature higher than a specific temperature and at a speed higher than a specific working speed. CONSTITUTION:The metallic plate is covered with crystalline thermoplastic resin, heated and drawn at a temperature higher than the grass transition point of resin and reheated at a temperature higher than the glass transition point and redrawn at a bending and pulling speed larger than 1m/min. Resin film obtains workability following the metallic material by being heated to a temperature higher than the glass transition point and is not damaged by tools, etc. Since organic film is made of crystalline thermoplastic resin and put in molecular orientation, corrosion resistance and heat resistance are improved. When bending and stretching are performed at a high speed, heat is generated by the internal friction of resin itself, molecular orientation at a high temperature is performed, corrosion resistance and heat resistance can be improved.

IPC: F04B49/06
Filed: 1981-03-13
Abstract: PURPOSE:To reduce the unnecessary consumption of energy when an unloaded state is continued for a long time by stopping the surplus compressors by means of a device for controlling the number of compressors in operation on the basis of a capacity control cmmand from each compressor. CONSTITUTION:There is provided a system by which information as to whether the compressors 1a-1d are performing the capacity control is fed to the device for controlling the nmber of operating compressors 7. As the input signals for said controlling device, the capacity control commands 8a-8d from the compressors 1a-1d are used. For example, when the discharge pressure has come into the preset range of pressure levels, if a compressor performing the capacity control is in an unloaded state, the discharge pressure is checked again after the lapse of a prescribed waiting time as shown in the accompanying figure. The compressor is stopped only when the unloaded state has conitnued for a prescribed period of time while the discharge pressure remaining within the range of preset pressures, thus preventing the wasteful consumption of energy.

Abstract: PURPOSE:To prevent the interference by a desired wave with an image frequency from occurring by setting the load of a gate grounding type amplifier at a tuning type load by a variable band-pass filter and a capacitor, and applying it as the selective load of a desired RF input frequency. CONSTITUTION:The load on the drain of a transistor 11 is formed in the tuning type load by the variable band-pass filter 80 and the capacitor 14.

Also. the load of the gate grounding type amplifier can be tuned selectively with the desired RF input frequency. Therefore, no amplifying operation is performed on the image frequency by the gate grounding type am plifier, and the interference by the desired wave with the image frequency can be prevented.
