In order to provide a rotary electric machine with a reduced size and improved weldability, the stator of a rotary electric machine has a segment coil formed by bending rectangular conductors, and a stator core having slots in which the segment coil is inserted. As for the weld parts formed at the tips of the lead parts of the segment coil which protrude from the end face of the stator core and are twisted together, at least one of the weld beads aligned in the radial direction of the stator is an oblong body that is long in the radial direction of the stator core, and the angle formed by the longitudinal direction of the oblong body and the axial direction of the stator core is less than 90 degrees in a core cross section that includes the central axis of the stator core.

Provided are a Li-ion battery (nonaqueous-electrolyte battery) 100 that includes a positive-electrode active-material layer 12, a negative-electrode active-material layer 22, and a sulfide-solid-electrolyte layer 40 disposed between the active-material layers 12 and 22. The sulfide-solid-electrolyte layer 40 includes a sulfur-added layer 43 in an intermediate portion in the thickness direction of the sulfide-solid-electrolyte layer 40. The sulfur-added layer 43 has a higher content of elemental sulfur than any other portion of the sulfide-solid-electrolyte layer 40. The sulfur-added layer 43 substantially does not have any pin holes. The sulfur-added layer 43 is formed by laminating a positive-electrode body 1 and a negative-electrode body 2 that are individually prepared and subjecting the electrode bodies 1 and 2 to a heat treatment so that a positive-electrode-side sulfur-added layer 14 of the positive-electrode body 1 and a negative-electrode-side sulfur-added layer 24 of the negative-electrode body 2 are softened and integrated.

A light pipe assembly includes a lamp assembly and a light pipe. The lamp assembly has a housing that holds a light source configured to emit light. The light pipe is elongated between an attachment end and an opposing distal end. The attachment end is received in the housing of the lamp assembly. The light pipe receives light emitted by the light source. Additionally, the light pipe includes surface elements that are configured to permit the light to emanate from the light pipe between the attachment and distal ends. The surface elements are arranged in a pattern that provides a predetermined distribution of light emanating from the light pipe.

In a light source apparatus, an alternating current is supplied to a high pressure discharge lamp from a power supply apparatus to light the lamp. The arrangement state of the lamp is detected by a detection circuit. When the lamp is horizontally arranged, electric energy, whose flow direction is from one electrode of the lamp to the other electrode, is set to be approximately the same as electric energy, whose flow direction is from the other electrode to the one electrode. When the lamp is vertically arranged, while a cycle, which is the same as a polarity change cycle in the horizontal arrangement, is maintained, electric energy, which flows from an upper electrode to a lower electrode, is set to be smaller than electric energy, which flows from the lower electrode to the upper electrode.

A high pressure discharge lamp has an electric discharge container with sealing portions formed at both ends of a light emission section, and electrodes made of tungsten. The electrode has a base end which is buried in the sealing portion. Tips of the electrodes face each other in the light emission section. Purity of the tungsten is 99.99% or more. The electrode has a large diameter portion formed at the tip of the electrode and an axis portion whose diameter is smaller than that of the large diameter portion. A part of a surface of the large diameter portion has a concavo-convex structure where a portion having grooves in a circumference direction and a portion having no groove are asymmetrically formed with respect to an axis of the electrode.
摘要:
A light pipe is configured to provide a wide effective angle of illumination while simultaneously providing a substantially uniform distribution of light along a length of the light pipe. One or more reflective surfaces not aligned with an inner surface are disposed such that when at least one reflective surface is illuminated, light is emitted from the light pipe at one or more specified angles of light emission. A plurality of reflection points are formed on the inner surface to cause the specified angles when at least one of the reflective surfaces is illuminated. A light pipe is also provided having one or more exterior protrusions configured to function as a secondary light source. A second portion of an outer surface of the light pipe has a radius of curvature which differs from the radius of curvature of the first portion of the outer surface.
