摘要:
An artificial blood vessel has a trunk portion which forms a part of the blood vessel and also has branch portions which are branched from the trunk portion. The branch portions are provided with access ports into which a needle, for discharging liquid out of a human body or introducing the liquid into the human body, is inserted. Tubular reinforcement members integrated with the blood vessel wall of the trunk portion are disposed at positions of the trunk portion, the positions being those from which the branch portions are branched, and at portions adjacent to the positions of the trunk portion. A lateral force at the time of needle insertion is borne by the reinforcement member, and this prevents the trunk portion from deforming. Thus, the configuration prevents the artificial blood vessel from deforming due to a force applied when a needle for discharging liquid from a human body or introducing the liquid into the human body is inserted into an access port of the artificial blood vessel.

An artificial blood has a trunk portion with both ends connected to blood vessels, and access branch portions and a shunt branch portion branched from the trunk portion. The access branch portions are disposed with a solid column-shaped access port that plugs these branch portions. The access port has a solid center portion and a tube-shaped peripheral portion disposed to surround the center portion. The peripheral portion is harder than the center portion and prevents the needle from deviating from the inside of the center portion. This enables a puncture to be easily made in a therapy in which a puncture is highly frequently made in a blood vessel.

In a closed housing of a magnetic disk memory device are accommodated a spindle motor for rotatably holding a magnetic disk medium for storage of information, a magnetic head for recording and reproducing information into and from the magnetic disk medium, a head positioning mechanism for moving the magnetic head to any position on the magnetic disk medium, and so forth. A printed board having thereon control circuit parts for controlling the spindle motor and the head positioning mechanism and recording/reproducing circuit parts for effecting the recording/reproduction by the magnetic head is arranged outside of the housing. An opening corresponding to a component of the magnetic disk memory device is formed in a certain region of the housing opposing the printed board. A shielding member for preventing a dust from entering into the housing is provided for the opening. The shielding member has a sheet-like or cup-like form and the device is constructed corresponding to the unevenness or uneven arrangement of components, thereby making it possible to reduce the thickness of the device. The commonization of the shielding member for disk devices is possible and a distance between a printed board and the housing can be reduced for the whole of the device.

A hook device having a hook body, a stopper for preventing the hook body from slipping off a member to be connected, an elastic member for biasing the stopper toward a slipping-off preventing position, and a connecting pin for connecting these components together. The stopper is formed with a slot having the connecting pin inserted therethrough. The slot has a stopper guide portion for permitting the stopper to move between the slipping-off preventing position and a slipping-off permitting position, and a stopper lock portion allowing the connecting pin to fit in when the stopper is further moved from the slipping-off permitting position. The hook device further has a stopper returning mechanism for moving a stopper unlocking knob portion toward the slipping-off preventing position.

A magnetic disk apparatus wherein a magnetic member mounted on a bobbin made of a non-magnetic material is disposed at a specific position effective for the full range of movement of a transducer head such that the magnetic member and thus the head is attracted by the leakage flux in a VCM, and the attracting force thus derived has a component that produces a rotation moment in only one direction around the pivot axis of the head to bias the head toward a non-data portion of a data storage disk.

A method for manufacturing a hydrocarbon oil, comprising: a first step wherein a feedstock oil containing an oxygen-containing organic compound and a water-insoluble chlorine-containing compound is brought into contact with a hydrogenation catalyst comprising a support containing a porous inorganic oxide and one or more metals selected from Group VIA and Group VIII of the periodic table supported on the support in the presence of hydrogen to generate a hydrocarbon oil and water in a vapor state by the hydrodeoxygenation of an oxygen-containing organic compound and convert the water-insoluble chlorine-containing compound into a water-soluble chlorine-containing compound; a second step wherein the water in the reaction product of the first step is maintained in a vapor state and the reaction product of the first step is brought into contact with a nitrogen-containing Brønsted base compound which has a boiling point at normal pressure of 100° C. or less and is water-soluble to obtain a product to be treated; and a third step wherein the product to be treated is cooled to a temperature not higher than the temperature at which water in a vapor state is liquefied to form an aqueous phase containing a water-soluble chlorine-containing compound and a nitrogen-containing Brønsted base compound and then separate the aqueous phase from an oil to be treated to obtain a product oil containing a hydrocarbon oil.

There is provided an apparatus which reduces a bleeding amount upon an operation.A bloodless treating apparatus used upon a surgical treatment of an objet comprises: (A) a fluid replacement supply unit which quantitatively supplies a fluid replacement into a blood vessel leading to the object (24); and (B) a fluid replacement withdrawing unit which quantitatively withdraws the fluid replacement having passed through the object (24) from a blood vessel coming from the object.
摘要:
An electric circuit for controlling a magnetic head is mounted on a flexible printed circuit (hereinafter referred to as "FPC"), and the FPC is arranged in a folded state within an enclosure. The FPC has an electronic circuit disposed on one side surface thereof, the one side surface being formed when the FPC is extended in a plane. Connectors are arranged on one end portion of the FPC for connecting to the magnetic head and external equipment. A support member is bonded to the surface of the FPC opposite to the surface mounting the electronic circuit, and by this supporting member the FPC is secured in a state folded in at least two within the housing of the magnetic disk apparatus.
