  • Publication number: 20240089344
    Abstract: A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).

  • Publication number: 20100270771
    Abstract: Walking auxiliary equipment 10 includes a walking unit 12 and a bogie 14. The walking unit 12 has a lumber frame 16 put onto the lumber region of a user, a below-knee frame 34 put onto the leg of a user, an above-knee frame 26 for coupling the lumber frame 16 to the below-knee frame 34, through a first joint K1 and a second joint K2, and an assistance force imparting device 102. The assistance force imparting device 102 includes a first actuator 104 for generating assistance force to flex the first joint K1, a second actuator 106 for generating assistance force to flex the second joint K2, a third actuator 108 for generating assistance force to extend the second joint K2, and a fourth actuator 110 for generating assistance force to extend the first joint K1.

  • Publication number: 20090300843
    Abstract: A postural change device used to allow imaging a plurality of postures while changing the posture of a portion to be examined of an object by means of a medical image diagnostic apparatus. The postural change device comprises a head-use balloon and a trunk-use balloon dispersedly arranged in a bag-form mat, and a compressor and a valve body carrying out parallel actions on the two balloons, that is, maximum expansion?medium expansion?complete contraction on the head-use balloon, and complete contraction?medium expansion?maximum expansion on the trunk-use balloon, whereby it is possible to sequentially change the cervical spine of the object from an anteversion posture to a neutral posture to a retroflexed posture.

  • Patent number: 7607380
    Abstract: A fluid pressure actuator includes: an actuator body which expands and contracts through supply/discharge of a fluid to generate a driving force; a sensor for detecting a condition of the actuator body; and a control part for controlling a fluid regulator for adjusting a pressure of the fluid supplied to and discharged from the actuator body based on a detection signal from the sensor. The sensor is mounted in the actuator body.

  • Publication number: 20090044696
    Abstract: In order to improve its durability, a fluid pressure type actuator is comprises an expansible/contractible body having opposite ends sealed by plug members and expands/contracts when fluid is supplied to and discharged from the body; a wrapping body for wrapping the outer peripheral surface of the expansible/contractible body and having its opposite ends fastened and fixed to the plug members; an inlet/outlet for fluid formed in the plug members; and an auxiliary member for preventing or suppressing local deformation in which the wrapping body expands outward when the fluid is supplied to the expansible/contractible body.

  • Patent number: 7413554
    Abstract: Provided is a wearable joint driving device in which a plurality of frame members are attached to a wearing body so as to be in contact with the outer surface of the wearing body. Between the frame members, there is mounted a fluid pressure type actuator. The fluid pressure type actuator has an expansion/contraction member and a net-like covering member covering the outer periphery of the expansion/contraction member. The fluid pressure type actuator undergoes a reduction in length through expansion of the expansion/contraction member to thereby generate a driving force. The frame members have a predetermined level of rigidity.
