A seatbelt retractor and method of incorporating a spindle into a retractor frame. The seatbelt retractor includes a spindle having a recessed portion in a cylindrical surface for retracting a webbing, and a retractor frame including two flat plate-shaped side walls that are provided in parallel via an interval (A) in order to support the spindle, each of the two side walls being provided with a circular through hole having a diameter (C). An element on a first end of the spindle is contained within a range of a distance (D) from a deepest portion of the recessed portion, and an element on a second end of the spindle is contained within a range of a distance (B) from the deepest portion of the recessed portion. The distance (D) is smaller than the height (C), and the distance (B) is smaller than the interval (A).

An X-ray tube is provided with a target that radiates primarily the characteristic X-ray of molybdenum. The target has an electron focal area of molybdenum base alloy containing molybdenum as a major component, and at least one of titanium and a combination of potassium oxide and silicon dioxide.

X-ray tube

The invention provides a rotary anode which has a graphite body having a plurality of radial slits and a target layer adhered to the upper surface of the graphite body. The target layer is a single layer of tungsten or a tungsten alloy, or a composite layer consisting of the single layer and a molybdenum layer. In the manufacturing process and in use of the rotary anode, a thermal stress which occurs in the graphite body is decreased, thus preventing cracking of the graphite body. The invention also provides a method for manufacturing the rotary anode.

Rotary anode for X-ray tube

The present invention provides a rotary anode for an X-ray tube which comprises an anode body formed of graphite, a preformed sheet formed of rhenium and bonded to the top surface of the anode body, and a target layer formed of tungsten or an alloy thereof and bonded to the top surface of the preformed sheet. This rotary anode may further comprise a preformed plate formed of molybdenum and interposed between and bonded to the preformed sheet and the target layer. Also disclosed is a method for manufacturing the rotary anode.
