Patent number: 6391083Abstract: A mixture for a powder metallurgy product, including iron powder, graphite powder and copper (Cu) of about 3.0 to about 5.0 weight percent. Iron powder includes iron grains which contain MnS therein. The mixture contains the MnS of about 0.65 to about 1.40 weight percent. The graphite powder is contained in the mixture such that an amount of carbon (C) in the powder metallurgy product is about 0.3 to about 0.7 weight percent. An amount (wt % C) of the carbon and an amount (wt % Cu) of the copper is determined to obtain a target fatigue strength FS (MPa) and a target hardness HR (HRB) based on a relation FS=66.63×(wt % C)+22.61×(wt % Cu)+280.84 HR=22.96×(wt % C)+2.99×(wt % Cu)+78.91.Type: GrantFiled: November 9, 2000Date of Patent: May 21, 2002Assignees: Kobeico Metal Powder of America, Inc., Kobe Steel, Ltd., Honda Giken Kogyo Kabushiki KaishaInventors: Nobuaki Akagi, Shinya Kawai, Masaaki Satoh, Yoshikazu Seki, Masaki Amano, Hideaki Ushio, Russell T.

Patent number: 6264718Abstract: A powder metallurgy product which is made from constituent including iron powder. The iron powder includes iron grains which contain machinability improving element in the iron grains. The machinability improving element is configured to improve machinability of the powder metallurgy product and has a pinning effect. An amount (Q) of the machinability improving element is adjusted such that an absolute value of a differential coefficient (dS/dQ) is at least a predetermined value, where (S) is a grain size of iron in the powder metallurgy product.Type: GrantFiled: May 26, 2000Date of Patent: July 24, 2001Assignees: Kobelco Metal Powder of America, Inc., Kobe Steel, Ltd.Inventors: Nobuaki Akagi, Shinya Kawai, Michael E. Lutheran, Masaaki Satoh, Hironori Suzuki

Patent number: 6038205Abstract: A spindle motor comprises a fixed journal, a hub for loading disks, a ball bearing for rotatably supporting the hub and an annular member fixed on one of the fixed journal and the hub. The fixed annular member is configured to create to create a small space with the hub or fixed journal which is opposite the one on which the annular member is fixed. When L1 is the dimension of a space between a top surface of a top disk and a surface of a member facing said top surface of said top disk, and L2 is the dimension of a space between a bottom surface of a bottom disk and a surface of a member facing the bottom surface of the bottom disk, the annular member has grooves for generating air flow directed toward the space of longer dimension, one of said dimensions L1 and L2.Type: GrantFiled: February 6, 1997Date of Patent: March 14, 2000Assignee: Sankyo Seiki Mfg. Co., Ltd.Inventors: Koichi Katakura, Masaaki Satoh

Patent number: 5438520Abstract: A method of creating data for an applique which has its lower and upper applique patches embroidered to lower and upper cloths, respectively, such that the lower cloth and applique patch and the upper cloth and applique patch can overlap and separate each other with a predetermined overlap margin. The applique data creating method includes the steps of: inputting synthetic contour data of the two applique patches when the lower and upper applique patches overlap each other with the predetermined overlap margin; inputting the individual overlap edge data of the lower and upper applique patches; creating the individual contour data of the lower and upper applique patches from the synthetic contour data and the individual overlap edge data; and creating the individual embroidering data of the lower and upper applique patches on the basis of the individual contour data of the lower and upper applique patches.Type: GrantFiled: April 1, 1994Date of Patent: August 1, 1995Assignees: Kabushiki Kaisha Barudan, Ippon Denpa Co., Ltd.Inventors: Masaaki Satoh, Akinori Kuroda, Masashi Asai

Patent number: 4777059Abstract: A product obtained by subjecting an isolated soybean protein and corn starch used as the raw materials to pressing and heating treatments in a twin-screw extruder exhibits its fibrous properties when it is immersed in warm water to dissolve out a part of the corn starch and a little amount of the soybean protein. This product is relatively tough. The corn starch is dissolved out in only a small amount upon the immersion in warm water and, therefore, the yield is high.Type: GrantFiled: December 5, 1986Date of Patent: October 11, 1988Assignee: The Nisshin Oil Mills, Ltd.Inventors: Shigeru Tanaka, Masaaki Satoh, Gyota Taguchi

Patent number: 4107478Abstract: An angle modulated wave demodulation system demodulates an input angle modulated wave by means of a phase locked loop system which comprises a phase comparator, which is operated responsive to an input angle modulated wave. A voltage controlled oscillator is supplied with a part of the output of the phase comparator which controls its oscillation frequency. The oscillator supplies its oscillation frequency to the phase comparator. The phase locked loop system has a lock frequency range which decreases its width when the level of the input angle modulated wave is below a predetermined level. The portion of this lock range in which the width of the lock range decreases is positively utilized. The voltage controlled oscillator oscillates at a frequency equal to the center frequency of the carrier of the input angle modulated wave, when the phase locked loop becomes unlocked.Type: GrantFiled: June 21, 1976Date of Patent: August 15, 1978Assignee: Victor Company of Japan, LimitedInventors: Nobuaki Takahashi, Kazunori Nishikawa, Yoshiki Iwasaki, Masaaki Satoh, Katsuhiro Ohba, Shinji Nakamura, Tatsuo Sawada, Nobuhide Ohsaki, Yasuo Itoh, Nobuaki Suda, Yasuhisa Okabe, Hideaki Ozaki
