Abstract: A chair-type massage machine includes a backrest for the back of the user to bear on, a seat for the user to sit in, and a reclining mechanism for pivotally moving the backrest and the seat. The reclining mechanism includes a single drive source to recline the seat while permitting the user to hold a related posture, the drive source being coupled to the backrest and the seat by a link assembly. The link assembly is operable to pivotally move the backrest from a raised position to a reclined position via an intermediate position by operating the drive source, the seat being tiltable to raise a front end thereof when the backrest is pivotally moved from the raised position to the intermediate position, the seat being tiltable to lower the raised front end thereof when the backrest is pivotally moved from the intermediate position to the reclined position.

Abstract: A pivotal lever has a first therapeutic member and a second therapeutic member positioned below the first member, for the members to grip and knead the shoulder of the person to be massaged as by the fingers of the acupressurist. A massage unit 20 comprises a pair of left and right pivotal levers 100 pivotally movably arranged on a chassis 21, and a first therapeutic member 200 and a second therapeutic member 300 arranged on each of the pivotal levers 100 and movable toward and away from each other. The first and second therapeutic members 200, 300 have motion conversion means 400 coupled thereto for converting the pivotal movement of the pivotal lever 100 into the movement of the first and second therapeutic members 200, 300 toward and away from each other.

Abstract: The invention provides a chair-type massage machine comprising a backrest and a seat which can be reclined by a single drive source while permitting the user to hold a relaxed posture. The chair-type massage machine comprises a backrest (20) for the back of the user to bear on, a seat (30) for the user to sit in, and a reclining mechanism (40) for pivotally moving the backrest (20) and the seat (30). The reclining mechanism (40) comprises a single drive source (42), the drive source being coupled to the backrest (20) and the seat (30) by a link assembly (50).

Abstract: A chair-type massage machine is provided which is adapted to give a twisting massage to the upper half of the body of the user. The massage machine comprises a seat 12 for the user to sit in, and a backrest 20 disposed at a rear end of the seat, the backrest being provided with a pair of opposite therapeutic air bags 30, 32 for massaging the back of the user. The pair of opposite therapeutic air bags 30 32 are arranged in a V shape and spaced apart by a large distance at an upper side of the backrest 20, the distance decreasing from portion to portion downward.

Abstract: In an external force measuring system comprising a piezoelectric element 61 or producing a charge when acted on by an external force, and a charge amplifier 7 chargeable with a variation in the charge produced by the piezoelectric element to output a voltage signal, the charge amplifier 7 comprises a feedback loop having an on-off controllable switch 8 connected in parallel therewith. The switch 8 is on-off controlled by a comparator 81 for comparing the output voltage with a reference value and is closed while no external force acts on the element.

Abstract: An apparatus for mounting electronic components on the surface of printed boards by a suction head assembly 4 coupled to a head lift mechanism comprises a force sensor 6 for measuring the pressure exerted on the component by a mounting operation, and a microcomputer 1 for preparing a control signal in accordance with the deviation of the value measured by the force sensor from a desired value of pressure on the component. The rotation of a head lifting motor 51 is controlled based on the control signal.

Abstract: A method for automatically forming wire frames which consists of the ordered steps of straightening continuously supplied wire stock, cutting the straightened wire stock into prescribed lengths, forming small ripples in portions of each section of the cut wire stock, ejecting and conveying the cut wire stock sections in a lateral direction, pooling the wire stock sections in successive order in a lateral direction, gathering together, removing and conveying a prescribed number of the pooled wire stock sections at given intervals, simultaneously bending a prescribed number of wire stock sections in the same plane as the ripples, removing and conveying the bent stock sections, pooling the conveyed wire stock sections in successive order in a lateral direction, separating the pooled wire stock sections into single sections spaced at equal intervals, intermittently feeding the separated wire stock sections into a press, pressing a three-dimensional bend into the fed wire stock sections and simultaneously ejecting
