摘要:
A surgical instrument for fastening together opposing portions of a body organ. The instrument comprises a first support for supporting the first opposing portion of the body organ, a second support opposing the first support, for supporting the second opposing portion of the body organ, and a displacement-preventing member connected to the first or second support for preventing the supports from displacing relative to each other. The member comprises a pin protruding from one of the supports and a hole formed in the other of the supports. The pin is made of thermoplastic resin. When heated, the pin is softened and deformed, whereby the first and second supports are secured to each other, fastening together the opposing portions of the body organ.

In the method and dissolving therapeutic apparatus for dissolving a coagulation within a living body, a medicinal liquid for dissolving the coagulation within the living body is injected into the living body, the injected medicinal liquid is left within the living body for a predetermined time and the fluid within the living body containing the coagulation dissolved by the medicinal liquid and the medicinal liquid is substantially all discharged out of the living body. A series of steps including at least respective injecting, leaving and discharging steps is repeated. Preferably, vibrating waves are radiated toward the coagulation during the leaving step.
摘要:
An ultrasonic treatment system for conducting treatment by converging ultrasonic waves which are generated outside of a body to a part to be treated in the body comprising an ultrasonic wave generator for generating the ultrasonic waves to be converged to the part to be treated; and an insertion tube connected to the ultrasonic wave generator for guiding an instrument, such as a syringe, employed to introduce and/or return a treatment material to the body.
摘要:
A soft solder of Pb alloy for semiconductor devices that contains 1 to 65 wt % of Sn or In or both, the balance being Pb and incidental impurities which include less than 50 ppb of radioisotopes and the count of radioactive alpha-particles being not more than 0.5 CPH/cm.sup.2. The solder exhibits high adhesive strength and good wettability. The properties of this material may be further improved by addition of 1 to 10 wt % of Ag.
摘要:
A laser beam machining method and a laser beam machining device capable of cutting a work without producing a fusing and a cracking out of a predetermined cutting line on the surface of the work, wherein a pulse laser beam is radiated on the predetermined cut line on the surface of the work under the conditions causing a multiple photon absorption and with a condensed point aligned to the inside of the work, and a modified area is formed inside the work along the predetermined determined cut line by moving the condensed point along the predetermined cut line, whereby the work can be cut with a rather small force by cracking the work along the predetermined cut line starting from the modified area and, because the pulse laser beam radiated is not almost absorbed onto the surface of the work, the surface is not fused even if the modified area is formed.

A substrate dividing method which can thin and divide a substrate while preventing chipping and cracking from occurring. This substrate dividing method comprises the steps of irradiating a semiconductor substrate 1 having a front face 3 formed with functional devices 19 with laser light while positioning a light-converging point within the substrate, so as to form a modified region including a molten processed region due to multiphoton absorption within the semiconductor substrate 1, and causing the modified region including the molten processed region to form a starting point region for cutting; and grinding a rear face 21 of the semiconductor substrate 1 after the step of forming the starting point region for cutting such that the semiconductor substrate 1 attains a predetermined thickness.

摘要:
When a drive wheel (3) of a vehicle is driven by a motor generator (10) that operates as a motor, electric power is supplied from a storage battery (20) to the motor generator (10). When the drive wheel (3) is braked by the motor generator (10) that operates as a generator, electric power is supplied from the motor generator (10) to the storage battery (20), and a first thermoelectric conversion element (11) is supplied with electric power from the motor generator (10) to cool the motor generator (10).
摘要:
A detection membrane (11) is joined to a first surface (10a) of an electrolyte membrane (10), and hydrogen gas is supplied to a second surface (10b) thereof. If the electrolyte membrane has a defect (10c), hydrogen gas leaks to the first surface, resulting in a change in electric resistance of the detection membrane near the defect. The defect is recognized by this change. FA hydrogen electrode (14) is joined to the second surface, and an electric circuit (17) is connected between the detection membrane and the hydrogen electrode. Hydrogen gas supplied to a space facing the hydrogen electrode is ionized at the hydrogen electrode, and hydrogen ions permeates through the electrolyte membrane and hydrogenates the detection membrane. Whether or not hydrogen ion conductivity is uniform is examined by measuring electric resistance of the detection membrane, which varies depending on the amount of hydrogen ions, for each of regions.
