摘要:
A process for producing a medical instrument, such as a stent and a guide wire, which has an excellent fatigue life; and a medical instrument, such as a stent and a guide wire, which has an excellent fatigue life. The process for producing a medical instrument includes: a preparation step of preparing a medical instrument including a NiTi-based alloy as a base material; and an ion irradiation step of irradiating the medical instrument prepared in the preparation step with Xe ions. The medical instrument is produced by irradiating a medical instrument including a NiTi-based alloy as a base material with Xe ions.
摘要:
An input device for providing signals for controlling a knitting machine. The device includes a mechanical information storage means and a switch means responsive to the contents of the storage means to provide a signal corresponding to the stored information. The storage means is disposed for operation either manually by a machine operator or electromechanically in response to instructions provided by other components of the machine. The device is incorporated in a program reading apparatus to specify feeding direction of the program carrier on the knitting machine.
摘要:
A method and apparatus for providing patterning instructions in a knitting machine by reading a program carrier and converting the readings to digital signals to be stored in a memory means. A manually operable member cooperating with the reading means allows the instructions to be recalled from memory to be selectively determined for controlling for the knitting operation.
摘要:
A die includes abase body and a modified surface layer. The base body includes tungsten carbide particles bonded by a bonding phase. The modified surface layer includes tungsten carbide particles and a filling material filled among the tungsten carbide particles to bond the tungsten carbide particles to each other. The filling material comprises copper. The modified surface layer is formed on at least a part of a surface of the base body.
摘要:
In a vacuum chamber, the edge of each blade group is subjected to an ion beam treatment under predetermined conditions using a plasma ion gun and argon as a medium, and is subjected to a plasma ion implantation of nitrogen plasma under predetermined conditions using a plasma ion implantation gun. As a result, it is possible to provide a blade member having an edge of a cutting quality enhanced by increasing the sharpness, a blade member having an edge of a rigidity enhanced by increasing the hardness, and a working apparatus capable of working those edges efficiently.
摘要:
Method for surface treating a die made of metal in which a low energy, pulsed electron beam, which does not scatter, performs a treatment over a wide area due to presence of anode plasma in a chamber in which the electron beam is formed to smooth and gloss a surface of the die and increase a surface hardness and corrosion resistance of the die. The irradiation may be performed with an energy density not less than 1 J/cm2 per pulse, at least 5 pulse irradiations and a pulse duration of at least 1 μs. A die subjected to the surface treatment method exhibits improved surface smoothness and glossiness, as well as high corrosion resistance.

摘要:
Wear-resistant and low-friction hard amorphous, diamond-like carbon coating (DLC) is formed directly on an eternal surface of a magnetic recording media sensor (MRMS). The coating demonstrates a high degree of hardness, low friction coefficient and moderate electric resistivity, providing abrasion-proof, low-clogging, static electricity-deterrent properties.
