Patent number: 4574262Abstract: A lamination of a resilient and elongate magnetic sheet and a conductor strip is rolled up around a magnetic winding core to form a roll, and then the roll is sintered to produce an intermediate product. The conductor strip has both ends at both sides of the magnetic sheet so that both ends of the conductor strip are respectively exposed at both sides of the roll. Terminal electrodes are respectively attached to the both sides of the intermediate product to complete the chip coil. Another magnetic sheet may be provided to make the thickness of the lamination substantially uniform throughout the entire area. A second conductor strip may be provided in the lamination so that a coil having a tap can be actualized. The shrinkages of the winding core and the magnetic sheet are selected so that a desirable sintered product will result without suffering from delamination or cracks.Type: GrantFiled: December 8, 1981Date of Patent: March 4, 1986Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshikazu Hamazawa, Tatsuro Hirai, Tunenobu Horikoshi, Tomio Ishida

Patent number: 4157317Abstract: A resin-bonded graphite body having controlled crystalline orientation and a density of at least 2.05 g/cm.sup.3, the body comprising 3 to 12 weight % of a thermosetting resin and 88 to 97 weight % of a carbonaceous powder, is provided which includes at least 50 weight % of natural crystalline graphite powder. The body has a high transverse strength and a very low electrical resistance in the direction parallel to the direction of the crystalline orientation, and is thus suitable for a dry battery electrode.Type: GrantFiled: January 6, 1978Date of Patent: June 5, 1979Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiro Nagasawa, Tomio Ishida, Yoshitaka Yoshikawa

Patent number: 3974105Abstract: An overtemperature and overcurrent resistor fuse has a resistor body with finely divided conducting powder and silica powder dispersed in an organic flux and resin. The conducting powder has a melting temperature in the range from 60.degree.C to 350.degree. C. This overtemperature and overcurrent resistor fuse has a relatively low electrical resistance below a selected melting temperature and has an irreversible abrupt increase of electrical resistance above the selected melting temperature range caused by serious overload or overheating conditions.Type: GrantFiled: May 29, 1974Date of Patent: August 10, 1976Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kunio Sato, Tomio Ishida, Kanji Sugihara

Patent number: 3968674Abstract: An elongated continuous steel round bar is cut to a specified length, and the cut piece is pressed by forging machine to form a workpiece including an annular portion and a smaller annular portion concentrically integrally projecting therefrom. An outer ring and an inner ring are simultaneously produced from the workpiece by an apparatus comprising an inner ring die and an outer ring die mounted on a stationary base, and an inner ring punch and outer ring punch opposing the dies and mounted on a movable ram. The inner and outer ring punches simultaneously punch out the inner and outer rings from the workpiece fitted to the inner and outer dies. In relation to this operation, a cam operates to depress a rolling member disposed in the rear of hollow portion of the inner ring die, whereby the foremost of like finished inner rings each pushed into the hollow portion of the inner ring die at every stroke of the ram is allowed to drop through the die assembly and is thereby automatically withdrawn.Type: GrantFiled: August 5, 1975Date of Patent: July 13, 1976Assignee: Sakamura Machine Co., Ltd.Inventor: Tomio Ishida
