摘要:
An endoscopic suturing device includes an endoscope, a curved needle detachably arranged at the distal end portion of or integrally embedded in the endoscope for suturing a tissue of the living body, a suture for suturing said tissue with the curved needle, and a drive arranged on the endoscope and operating the curved needle.
摘要:
A surgical manipulator system comprising an operation device, a slave manipulator, a medical device, and a controller. The operation device is located in a region to be operated by a surgeon. The slave manipulator can have access into a surgery region. The medical device is held by the slave manipulator and can be moved a body cavity. The controller can operate in a first mode to move the slave manipulator or the medical device, or both, such that the axis of the medical device passes a fulcrum fixed in a space even before the medical device is inserted into the body cavity.
摘要:
A photochromic composition comprising (a) 100 parts by weight of a di(meth)acrylate compound represented by the formula (I): ##STR1## wherein R.sup.1 s each independently represent hydrogen or methyl, R.sup.2 s and R.sup.3 s each independently represent alkylene having 1 to 4 carbon atoms, X represents halogen other than fluorine, Y represents oxygen or sulfur, and m is an integer of 0 to 4, and (b) 0.01 to 5 parts by weight of a photochromic compound. The photochromic composition is excellent in heat resistance, mechanical strength, adhesion to a hard coat layer and moldability, and the photochromic properties thereof is highly resistant to light. By the use of the photochromic composition, a thin and light-weight photochromic lens or the like can be obtained.

A wrist driving mechanism for an industrial robot has a first base wrist unit (13) supported on the free end of a robot arm (11) and capable of rotating about a first axis (.gamma.). The first base wrist unit (13) is mounted with a second base wrist unit (14) capable of rotating about a second axis (.beta.). The second base wrist unit (14) is mounted with a fore wrist unit (15) capable of rotating about a third axis (.alpha.). The robot arm (11) is provided along the longitudinal direction thereof with a first power transmitting unit (16) for transmitting a rotative power to the first base wrist unit (13). A second power transmitting unit (19) for transmitting a rotative power to the second base wrist unit (14) is formed along the robot arm (11) and the first base wrist unit (13). A motor (25) for driving the fore wrist unit (15) for rotation is mounted on the first base wrist unit (13). The driving shaft of the motor (25) is coupled with a first transmission shaft (26) extended along the second axis (.beta.). The first transmission shaft (26) is connected through a gear train (27) to the second transmission shaft (28) extended along the third axis (.alpha.) and the second transmission shaft (28) is connected to the fore wrist unit (15). The second transmission shaft (28) is associated with a reduction gear mechanism (31).

摘要:
A molten metal supplying container, comprising a container capable of storing a molten metal and loading the molten metal to the inside thereof or supplying the molten metal to the outside thereof by controlling a difference in pressure between inside and outside of the container, a passage allowing the inside and outside of the container to communicate with each other to have the molten metal flow therethrough, a lid disposed to cover the first opening having a second opening with a diameter smaller than the first opening and a hatch provided at the second opening capable of being opened and closed, having a passage communicating inside and outside the container. The passage is used, for example, to control inner pressure of the container and to insert the electrode for detecting the surface level of the molten metal.
摘要:
A treatment method includes heating a treatment target object under reduced pressure in a hermetic zone to vaporize a component of the treatment target object, and opening a hermetic door and inserting a tube from a side of a treatment system for the vaporized component adjoining the hermetic zone with the hermetic door therebetween such that the tube shields the hermetic door from the hermetic zone to introduce the component vaporized from the treatment target object to the treatment system side.
