    摘要： The objective of the present invention is to provide a titanium alloy vacuum container and vacuum parts that can easily achieve an ultra-high vacuum in a short time through vacuum evacuation.The titanium alloy of the titanium alloy vacuum container and vacuum parts has a compact structure composed of fine grains, each having a size of approximately not more than 10 μm, with a surface that is exposed to at least vacuum being set to have a surface roughness of not more than 50 nm; and in this structure, preferably, the surface roughness thereof may be set to not more than 10 nm, the titanium alloy may have a hardness in a range of not less than 230 Hv to not more than 310 Hv, and the titanium alloy may have a passivity surface film made by a thin titanium oxide layer or nitride layer that is formed on the surface thereof. The titanium alloy, which is desirably used in such titanium alloy vacuum container and vacuum parts, contains 0.3 wt. % to 0.5 wt. % of iron and 0.3 wt. % to 0.5 wt. % of oxygen, and the remainder thereof is made from Ti obligatory impurities.

    摘要： The inverter device includes an inverse conversion circuit which converts a supplied direct-current electricity into a alternating-current electricity having a predetermined frequency, and is designed to drive a motor for a rotary machine, at various speeds, in which the switching control of the inverse conversion circuit is performed by a digital processor. In this inverter device, a timer interrupt process having an independent constant processing cycle which is not directly related to the processing cycle of the system control in the digital processor is assigned. In the timer interrupt process, whether or not switching of the inverse conversion circuit is required is determined, and the switching control is carried out on the basis of the determination.

    摘要： The present invention provides a high strength titanium alloy useful as a material for products such as ornaments, products such as ornaments made of the titanium alloy, and a method for producing the products using the titanium alloy as a material. The high strength titanium alloy is capable of attaining high machinability, and the product made of the titanium alloy is excellent in beauty and decorativeness while being hard to made flawed or concaved. According to the present invention, the titanium alloy includes iron of 0.20 to 0.8 mass percent and oxygen of 0.20 to 0.6 mass percent, or iron of 0.2 to 1.0 mass percent, oxygen of 0.15 to 0.6 mass percent and silicon of 0.20 to 1.0 mass percent, with the balance of titanium and inevitable impurities. A method for producing a product using the titanium alloy as a material includes a steps of hot forging the titanium alloy at a temperature of (.beta.-transformation temperature -200.degree. C.) or higher, and then cooling it, thereby giving a high strength to the product.
