Abstract:
For connecting a board member inserted in a board insertion direction, a board connector includes a contact with a first and a second beam portion, a housing holding the contact, and an actuator integral with the first beam portion. The first and the second beam portions include a first and a second clamping portion, respectively, for clamping therebetween the board member. The actuator includes an effort point portion formed forward with respect to the first clamping portion in the board insertion direction. When an operator inserts the board member into the board connector, the board member pushes and moves the effort point portion.

Abstract:
In a connector including first and second contacts having first and second contact points, respectively, an actuator is provided rotatable between a closed position and an open position and includes a cam portion faced to a connection object and a cutout portion adjacent to the cam portion. The first contact further has an engaging portion and a first beam portion elastically supporting the engaging portion to a housing. The engaging portion has a recess faced to the connection object and engaged with the cam portion. The second contact further has a contacting portion disposed at the cutout portion and a second beam portion elastically supporting the contacting portion to the housing. The contacting portion has a shape such that the contacting portion surrounds the cam portion in cooperation with the recess and biases the actuator towards the open position when the actuator is located near the open position.
Abstract:
A valve is included as part of a medical appliance used to transport an artificial blood vessel into a body through a catheter. The valve is formed by a membrane having a plurality of holes which are normally closed and which can be pushed to open against elasticity of the membrane to permit a plurality of devices used to transport the artificial blood vessel to be passed through the holes in parallel with each other. In a preferred embodiment, a hole is provided at the center of the membrane and three other holes are equi-spaced from the center hole; equal spaces are also provided between adjacent ones of the three holes. A relatively thick embankment or projecting portion is preferably provided extending between every pair of adjacent holes, to avoid breakage of the membrane therebetween upon parallel insertion of devices through the holes.
Abstract:
The artificial blood vessel A comprises a front end wire ring 101, a rear end wire ring 102 arranged facing to the front end wire ring 101, a tubular cover 7 which connects the end wire rings 101, 102, and a plurality of intermediate wire rings 12 arranged spaced apart from each other between the front end wire ring 101 and the rear end wire ring 102. Each of the front end wire ring 101, the rear end wire ring 102 and the intermediate wire rings 12 are given flexibly foldable elasticity. The circumference of the front end wire ring 101 is equally divided into four by dividing points 411, 421, 431, 441. Hooking means 13 are formed for a front pull string to be passed through at the dividing points 411, 431. The circumference of the intermediate wire ring 12 is fixed to the tubular cover 7 by suturing or with adhesive at the positions 513, 523, 533, 543 which correspond to the midpoint 511 between the dividing points 411, 421, the midpoint 521 between the dividing points 421, 431, the midpoint 531 between the dividing points 431, 441, and the midpoint 541 between the dividing points 441, 411.
Abstract:
A developing roller includes a magnet roller and a rotatable sleeve thereon. The sleeve is covered with a surface coating of a metal, alloy, metal nitride, metal oxide, metal carbide or metal sulfide by dry plating. The coating has a resistivity of up to 0.01 .OMEGA.cm. The sleeve is fully wear resistant at its surface. Formation of the coating by dry plating minimizes the variation of coating thickness to improve the dimensional precision of the sleeve surface. The developing roller and a developing apparatus equipped therewith can produce images of quality for a long time.
Abstract:
Disclosed is an improved balloon catheter having a three-layer balloon tube fixed to and enclosing an apertured end of an elongated flexible fine tube. The three-layer composite balloon tube is composed of inner and outer rubber tubes and an intervenient cloth bag, which is effective to hold the shape and size of the expanding balloon appropriately for the purpose and to raise and keep the inner-pressure of the expanding balloon at an elevated value without any fear for rupturing a hollow organ of a human body. A pair of rubber bands are dispersed about portions of the balloon to initially restrict expansion of said portions at a stenosis of the hollow organ.
Abstract:
A green tire building process comprises: the steps of: jointing both longitudinal ends of a belt-like tread rubber for producing an endless tread band, and applying the endless tread band on an inner periphery of an annular face: jointing both longitudinal ends of a belt-like breaker ply for producing an endless breaker band, and disposing the endless breaker band within said endless tread band with its mid-circumferential plane being aligned with that of said endless tread band; expanding the endless breaker band radially and applying the endless breaker band on the inner periphery of the endless tread band for building a tread breaker assembly; disposing a cylindrical green case within and in coaxial relation with the tread breaker assembly; deforming the cylindrical green case toroidally to be applied on the inner periphery of the endless breaker band for integrally building the cylindrical green case and the tread breaker assembly.
Abstract:
An endovascular treatment aiding device is an endovascular treatment aiding device including a flexible shaft; a filter fixed to the shaft such that an opening section is formed in the proximal side, wherein a ring having elastic restoring force is fixed to the opening section, which filter is capable of being opened and closed in an umbrella-like manner, and is in a conical shape having a bottom formed by the ring when the filter is open; and a linear supporting member fixed to the ring and a part of the shaft such that they are connected to each other, which linear supporting member enables closing the filter by application of an external force to the proximal side; wherein coils formed with a radio-opaque material is/are wound around the ring; when the filter is closed, a plurality of mountains pointing toward the distal side and a plurality of valleys pointing toward the proximal side are alternately formed in the ring to form a shape in which the mountains are positioned close to each other, and the valleys are positioned close to each other; and the coils are arranged on the ring such that the coils contain the positions fixed by the supporting member on the ring, but do/does not contain the positions of the peaks of the mountains and the peaks of the valleys.
