Patent number: 6705819Abstract: A feeder for chip components is provided wherein the chip components can be supplied with high stability even in high-speed operation by operating a conveying member at a lower speed than that of a chip mounter and operating the conveying member even when the chip mounter is stopped. The chip components on a belt are supplied in one direction by lowering a feed lever according to the input load from a chip mounter so as to drive the belt connected to the feed lever via a transmission mechanism intermittently in one direction. urging means is provided for urging the feed lever in the returning direction by storing the input load of the chip mounter as energy while an eddy current damper is provided for delaying the returning operation of the feed lever relative to the returning operation of the chip mounter. When the chip mounter operates downwardly, the feed lever is moved downwardly by linking to the chip mounter while the conveyor belt is maintained in a stationary state.Type: GrantFiled: October 4, 2000Date of Patent: March 16, 2004Assignee: Murata Manufacturing Co., Ltd.Inventors: Akira Nemoto, Shigeki Takahashi, Nihei Kaishita, Mitsuhiro Namura

Patent number: 6685052Abstract: A feed lever is lowered, correspondingly to the load input of a chip mounter. A rotary drum is intermittently moved through a conversion mechanism, intermittently in one direction. Chip components placed in a component accommodation chamber are aligned and discharged. When a rotation resistance larger than a predetermined value acts, a belt is slid, and breaking of a chip component is prevented.Type: GrantFiled: October 11, 2000Date of Patent: February 3, 2004Assignee: Murata Manufacturing Co., Ltd.Inventors: Akira Nemoto, Shigeki Takahashi, Nihei Kaishita, Mitsuhiro Namura

Patent number: 6666423Abstract: A ratchet-type lever mechanism for seat lifter, which comprises a brake unit whose shaft is connected with a mechanism of the seat lifter, two ratchet gear wheels provided about the shaft of brake unit, a shaft rotatable in a spaced-apart relation with the brake unit shaft, an operating lever connected with the shaft, and a sector ratchet gear element provided between the operating lever and two ratchet gear wheels. The sector ratchet gear element is so arranged in the lever mechanism to enable a user to rotate the operating lever in usual way without confusion about direction of rotation of the lever to cause upward and downward motions of the seat lifter. The sector ratchet gear element may be of an outwardly-toothed type having two outwardly toothed arcuate gear teeth and two sector gear portions, or may be of an inwardly-toothed type having two inwardly toothed arcuate gear teeth.Type: GrantFiled: May 31, 2002Date of Patent: December 23, 2003Assignee: Tachi-S Co., Ltd.Inventor: Akira Nemoto

Publication number: 20030222492Abstract: A locking/unlocking mechanism for headrest, which is provided in a headrest holder in which a headrest stay is slidably inserted, comprising: an elastic lock element secured in the headrest holder; and an unlocking hole so formed in the headrest holder as to lead to the elastic lock element. The elastic lock element can be engaged in an ordinary stopper notch formed in the headrest stay to prevent removal of the headrest from a seat back of seat, but can be disengaged therefrom by inserting a tool into the unlocking hole so as to resiliently bend the elastic lock element away from the stopper notch, thereby allowing removal of the headrest from the seat back. Preferably, the elastic lock element is formed in a generally “U” shape.Type: ApplicationFiled: May 31, 2002Publication date: December 4, 2003Applicant: Tachi-S Co., LtdInventors: Akira Nemoto, Hiroaki Ichikawa

Patent number: 6637584Abstract: A component carrying device has a simple constitution, and is capable of lining up components and carrying them in one direction with high reliability. The device comprises a guide groove for lining up components into one line and guiding them; a carrying member, provided on the bottom face of the guide groove, which can move forward and backward along the direction of the groove; and driving means, for driving the carrying member forward and backward at a higher speed when moving backward than when moving forward. The speed of the carrying member when moving forward is a speed at which a predetermined sustained frictional force acts between the carrying member and the components, which are mounted on the top face of the carrying member; and the speed of the carrying member when moving backward is a speed at which the frictional force between the carrying member and the components mounted on its top face, substantially breaks, so that the components are carried forward by the difference in frictional force.Type: GrantFiled: September 28, 2001Date of Patent: October 28, 2003Assignee: Murata Manufacturing Co., Ltd.Inventors: Shigeki Takahashi, Nihei Kaishita, Akira Nemoto

Publication number: 20030183472Abstract: A ratchet-type lever mechanism including two ratchet gear wheels and a bifurcated ratchet pawl member for selective meshed engagement with one of the two ratchet gear wheels. The bifurcated ratchet pawl member is simply bent from a plate material into such an offset configuration having a first toothed pawl portion and a second toothed pawl portion bent from that first one in an offset manner so that the two pawl portions are in correspondence with the respective two ratchet gear wheels. This ratchet-type lever mechanism has a simplified connection structure allowing both of the bifurcated ratchet member and an operating lever to be securely connected on an input shaft, whereby the input shaft is made short in length, thereby making thin a whole size of the lever mechanism. A restriction element for rotation of the bifurcated ratchet pawl member may also be mounted on that input shaft for that purpose.Type: ApplicationFiled: November 8, 2002Publication date: October 2, 2003Applicant: Tachi-S Co., Ltd.Inventor: Akira Nemoto

Patent number: 6484995Abstract: A seat lifter for height adjustment of vehicle seat, which has a lifter linkage for vertical movement of the seat and a drive mechanism therefor. The lifter linkage includes a pair of links, a bell crank portion formed in one of the two links, and a rotation transmission link element including a sector gear which is operatively connected with the bell crank portion. The drive mechanism comprises a ratchet-type lever mechanism operatively connected via a brake unit with the lifter linkage, the arrangement of which ratchet-type lever mechanism is such that only one-stroke operation of a lever causes a bifurcated ratchet pawl to rotate so as to bring a selected one of its two pawl portions to engagement with a ratchet gear wheel, thereby allowing for automatically selecting a desired operative direction without any switch-over operation and then continuously transmitting a certain amount of rotation force to the lifter linkage, so that the vehicle seat can easily be raised or lowered to a certain level.Type: GrantFiled: July 20, 2000Date of Patent: November 26, 2002Assignee: Tachi-S Co., Ltd.Inventor: Akira Nemoto

Patent number: 6257394Abstract: A part-conveying apparatus allows parts to align and slide down a sloped chute without stacking therein. The part-conveying apparatus has a chute sloped to align and slide down parts, and a first mobile blade for slidably supporting the parts in a bottom section of the chute in the direction of the chute 9. The lower end section of the chute is connected to a horizontal guide path, and a second conveying blade movable forward and backward is provided in a bottom section of the guide path. The second conveying blade reciprocates in a manner so as to move backward faster than to move forward, thereby conveying forward the parts placed thereon. A projection in the lower end of the first mobile blade engages with a groove of the second mobile blade so as to cause fine movements of the first conveying blade in the direction of the chute in synchronous with back and forth movements of the second conveying blade 26. This allows the parts to side down.Type: GrantFiled: June 30, 1999Date of Patent: July 10, 2001Assignee: Murata Manufacturing Co., Ltd.Inventors: Shigeki Takahashi, Nihei Kaishita, Akira Nemoto
