An indwelling catheter comprises a tube, a female connector and an elastically deformable hemostasis valve which can be pressed by a male connector. An opening taper portion tapered forwardly is formed in a longitudinal intermediate portion of an inner circumferential surface of the female connector. The elastically deformable hemostasis valve is provided longitudinally slidably in the opening taper portion of the female connector and an inside portion extending rearwardly from the opening taper portion. The hemostasis valve includes; a body having a hollow form opened at its front and rear ends or a tubular portion fitted over the connecting portion from a rearward direction; and an openable / closable portion being opened by elastic deformation of the body or the tubular portion.

A composite resistive to high-temperature corrosion and abnormal oxidization, maintains original excellent high-temperature characteristics of Ni alloys over a long period of time, and suitable for applications in a high-temperature such as gas turbines, jet engines, and elements for exhaust-gas systems. A heat-resistant Ni-alloy composite has excellent high-temperature oxidation resistance, including a Ni-alloy substrate that has been subjected to an Al-diffusing treatment. The surface coat has a multi-layer structure including an inner layer composed of an α-Cr phase and an outer layer composed of a β phase (Ni—Al—Cr) and a γ′ phase (Ni3Al(Cr)) on the substrate surface. The Al content in the outer layer is at least 20 atomic percent. The α-Cr phase functions as a diffusion-barrier layer. The outer layer retains and secures a high Al content required for self-regeneration of a defective portion of the Al2O3 layer damaged in an operating condition.

There is disclosed a hydraulic actuating device for actuating a shift rod in particular of a gearbox for motor vehicles, which comprises a cylinder chamber provided in or on a gear housing for accommodating a shift piston which is actively connected to the shift rod and which divides the cylinder chamber into two working chambers which can selectively be acted upon by a pressure medium from a reservoir for the latter, said working chambers being separated from one another by means of a sealing arrangement arranged on the shift piston. The sealing arrangement is designed in a valve-like manner so that, when at least one working chamber is acted upon by pressure medium, it connects said working chamber to an auxiliary chamber which is delimited by the sealing arrangement and which in turn can be connected to the reservoir for the pressure medium. As a result, a cost-effective hydraulic actuating device is provided which is vented in a simple and efficient manner during operation from the working chambers via the auxiliary chamber to the reservoir.

Disclosed is a therapy device for edema and neuropathy. Colored light within a visible light wavelength range, which is known to be useful for treating edema and neuropathy, is irradiated to a treatment area such as acupuncture points on a foot or a hand, or the surface of the skin, thereby relaxing the smooth muscle tissue of tissue cells with edema or neuropathy, facilitating peripheral vascular circulation and lymphatic circulation, and inducing the secretion of a material for treating edema and neuropathy.

An apparatus and method for identifying the flexor retinaculum of the carpal tunnel, injecting an effective amount of an agent into at least a portion of flexor retinaculum or tissue adjacent thereto, wherein the agent is configured to weaken the flexor retinaculum. The system may further include means for increasing the tensile stress in the flexor retinaculum post-injection using hand exercises, thereby weakening its structural integrity and decreasing the pressure within the carpal tunnel that impairs median nerve function.

A switching semiconductor device is provided, in which a negative gate voltage can be applied to the semiconductor device in an OFF state so as to increase a breakdown voltage of the gate junction without impairing a normally-off function of the semiconductor device and the ON-resistance. The switching semiconductor device is fabricated by using a semiconductor substrate with a band gap of 2.0 eV or more. In a JFET structure where a p+ type gate region and an n type source region are in contact so that a negative gate voltage can be applied, the p+ type gate region and an n+ type source region with a high impurity concentration are disposed with interposing an n type source region with an impurity concentration lower than that of the p+ type gate region and higher than that of a drift region of the JFET therebetween.
