Patent number: 6388843Abstract: A suspension for disc drive having a load beam and a flexure is provided with a limiter mechanism for regulating the movement of the flexure. The flexure includes a tongue portion provided with a magnetic head slider and a pair of outrigger portions situated individually on the opposite sides of the tongue portion. The limiter mechanism is provided with a nipping portion that is formed by bending part of the load beam. The nipping portion includes a first checking portion facing one surface of the flexure across a gap, a connecting portion situated ahead of the flexure, and a second checking portion extending rearward from the connecting portion and facing the other surface of the flexure across a gap.Type: GrantFiled: September 24, 1999Date of Patent: May 14, 2002Assignee: NHK Spring Co., Ltd.Inventors: Yasuji Takagi, Koji Uozumi, Akihiro Takei, Jyun Soga, Kenichi Takigawa

Patent number: 4798488Abstract: A dot matrix print head in which the mass of the armature is reduced by providing a groove in the armature in the portion where the magnetic flux density is relatively low. The armature may be advantageously attached to a sheet spring by laser welding applied from the bottom surface of the groove without creating craters in the external face of the sheet spring. Reduction in the mass of the armature allows a substantial increase in the print speed of the print head. Use of laser welding reduces the manufacturing cost of the print head and the absence of any craters in the external face of the sheet spring is favorable for the performance of the magnetic circuit of the print head.Type: GrantFiled: May 7, 1987Date of Patent: January 17, 1989Assignee: NHK Spring Co., Ltd.Inventor: Koji Uozumi

Patent number: 4749290Abstract: In a print head comprising a plurality of magnetic circuits each of which comprises an armature supported by a spring, a permanent magnet for biasing the armature in one direction, and an electromagnet which can be energized so as to cancel the biasing force of the permanent magnet, so that a print wire fixed to the armature may be driven by energizing the electromagnet and thereby driving the armature with the restoring force of the spring. The cross-sectional areas of the paths of magnetic flux between neighboring electromagnet circuits are made uneven. This can be achieved by providing base portions which are common to two electromagnet core portions. Thereby, the print pressure of all the print wires is made uniform and an increase in printing speed and improved print quality can be achieved at the same time.Type: GrantFiled: August 7, 1986Date of Patent: June 7, 1988Assignee: NHK Spring Co., Ltd.Inventor: Koji Uozumi
