Title: Sputtering method
Inventor: MIYAZAKI MASAHIRO
IPC: B01J19/08
Filed: 1982-05-21
Abstract: PURPOSE:To enhance the sputtering rate of an opposed target system, by a method wherein inclination is provided to the surfaces of two opposed targets and plasma discharge is generated between said targets. CONSTITUTION:The opposed surfaces of targets 11 attached to holders 5, 15 so as to be mutually opposed in parallel relation to each other are formed into a serrated shape. The length of the surface 11a thereof opposed to the sputtering surface 12a of a base plate 12 arranged at right angles with respect to the long axis of the target is made longer than that of the surface 11b thereof not opposed to said sputtering surface 12a. Plasma discharge is generated between these targets 11 to carry out sputtering. In another case, the cross sectional area of each target is formed into an equilateral triangle. By this method, the sputtering rate of sputtering due to an opposed target system can be enhanced.

Title: Sewage purifying apparatus based on fine gas bubble
Inventor: KUNO TAKEO
IPC: C02F1/465
Filed: 1994-03-18
Abstract: PURPOSE:To purify water with a simple system by jetting fine gas bubbles, whose buoyant force is slight in water against the surface tension of water, to the water and floating sewage in scum-like state in the water surface and separating sewage. CONSTITUTION:Two types of electrodes; an anode (a side part anode plate 4) and cathodes (a side part cathode plate 5 and a bottom part cathode plate 6) are put in water and d.c. electricity is supplied between the electrodes, so that fine gases are produced out of the cathodes and anode. Fierce convection is generated in the water by the produced gases and sewage in the water floats like the scum based on the rising function of the fine gases. Sewage purification in a water tank 1 is carried out by filtering the sewage by a filtering apparatus, a filter medium, etc., installed near the water surface. In the case this water purifier is used as a water purifier for general domestic use, chlorine in tap water can be removed by the fine gas bubbles. Also, the water purifier can be used to purify effectively the sewage such as filthy water of aquarium fishes, which floats and does not precipitate.

Title: Producer of magnetic recording medium
Inventor: MATSUZAKI SOUICHI
IPC: G11B5/84
Filed: 1983-05-16
Abstract: PURPOSE:To increase the attachment intensity of a ferromagnetic metal by providing a vacuum pump near an area where said metal is attached to a substrate at a high incident angle. CONSTITUTION:An electron beam 13 is irradiated to an evaporation source 6 from an electron beam source 8 to evaporate a ferromagnetic metal 7. The evaporatd metal 7 is attached obliquely and at a high incident angle to a substrate 3 which is traveling on the circumferential side surface of a back roll 5. A higher degree of vacuum is obtained at a place near the area where the metal 7 is attached to the substrate 3 at a high incident angle than the area where the attachment of the metal 7 is done at a low incident angle. Therefore the floating matters which prevents evaporation of the metal 7 are reduced at the area of a high incident angle. This producer increases the attachment intensity of the metal 7 to the substrate 3.

Title: Color image display device
Inventor: IHARA FUJIO
IPC: G09G5/36
Filed: 1995-04-11
Abstract: PURPOSE: To display an image with less deterioration in picture quality even when respective images are decided equally and displayed with the number of limited colors as a whole by newly forming a color table of an image based on the color table used for the display of the image at present and color impor tance of whole use colors of the image displayed newly. CONSTITUTION: Colors of all pixels of an original color image 1a are summed up by a color frequency totalize means 2 as all color frequencies to be stored in a color frequency table 3 in order of frequency. An importance conversion means 4 calculates relative frequencies of respective colors by dividing e.g. the color frequencies of the color frequency table 3 by the number of all pixels to store them in a color importance table 5. A display color re-construction means 6 adds the values of the color importance table 5 to the importance of a display color table (old) 9, and rearranges the results in order of high importance to store them in a display color table (new) 10. At the same time, a new-old color number correspondence table 7 is formed.  A color correction means 8 forms a really displayed color image 11 from the original color image 1a and the new-old color number correspondence table 7.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of vibration and rotary dispersion without generating deflection at the time of high speed rotation by forming a propeller shaft wherein universal joints are attached to both side end parts of a steel pipe formed out of a plurality of bellows shapes at prescribed intervals. SOLUTION: A steel pipe 21 is formed out of a plurality of bellows shapes 22 at prescribed intervals P. The prescribed intervals are taken as 30 to 70 mm, and the number of the bellows shapes 22 are selected within 6 to 12 pieces. A shaft is constituted by attaching yokes 13, 14 of universal joints 11, 12 on both end parts of the steel pipe 21. A propeller shaft 1 is attached between a transmission directly connected to a vehicular engine and a final decelerator in which a differential device is assembled, an rotary output of the engine is received through the transmission at the time of normal vehicle operation, and is transmitted to wheels through the final decelerator and the differential device.

Title: Method of thawing and device therefor
Inventor: SETO SEIICHIROU
IPC: A23L3/36
Filed: 1978-07-12
Abstract: PURPOSE: The latent heat of fusion is added to the thawing tank under pressure, thus thawing the frozen products at low temperatures in a short time.  
     CONSTITUTION: Cover 4 is turned and the opening of thawing tank 1 is completely opened. The frozen products are charged into the tank and clean water for thawing is poured to the prescribed level. Then, the cover is shut and switching valve 17 is switched so that the pressurized fluid flows into the pipe for pressurizing, then the valve 30 is closed. Consequently, the liquid from pump 14 pushes piston 33, resisting the force of spring 35, and compresses the piston room 34. Thus, pressurized air is pushed from the bottom into the tank 1 to raise the pressure in the tank. After the pressure reaches the prescribed value, the valve 17 is turned to neutral and the pressure is kept for a given hour, such as 40 min. In the meantime, the thawing is completed, then the operation valve 30 is opened by switch 37 and the pressure in the tank 1 is gradually reduced. When the pressure comes to zero, the thawing process is finished and the thawed products are taken out of tank 1.

Abstract: PURPOSE:To make the rigidity of a pivot section higher and, at the same time, to make the floating quantity of a head slider uniform, by setting the main axis line of the transducer of the head slider to a desired position and the position of the pivot section of a carriage to a prescribed location. CONSTITUTION:The main axis line (l) of the transducer of a head slider 1 supported by an arm 3 united with a carriage 4 which is swung by a voice coil with a pivot 5 at the center by means of a suspension 2 is extended in the direction which is almost equal to the tangential line of the tracks at the inner side from the central part of the recording track area of a recording medium 8. Depending upon the position setting of the line (l), the yawing angle becomes less at the innermost recording track and more at the outermost recording track and the floating quantity of the slider 1 become almost uniform at the inner and outer peripheries of the recording track area. On the other hand, a high-rigidity one can be used for the pivot 5 since the pivot 5 is positioned to the outside of the line (l) against a medium 8 and does not approach the medium 8. Moreover, high-speed seeking can be performed since the arm 3 can be made shorter.
