Title: Method for inspecting weld-bonded part of plastic tube
Inventor: MIHARA KEIJI
IPC: G01N29/04
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To inspect a plastic tube with sufficient accuracy by subjecting a plastic tube not bonded or a standard sample of the same size to an ultrasonic flow detection, obtaining an A scope whereby echoes at an end face of the tube can be distinguished, and inspecting a bonded part of the plastic tube under the same condition. SOLUTION: An ultrasonic flow detection element is arranged at a predetermined position of an end part of a plastic tube not bonded or a standard sample piece of the same size to carry out a flaw detection. An A scope S is displayed. An angle of refraction and a pulse frequency of propagating ultrasonic waves are changed variously at the detection time, so that an angle of refraction θand a pulse frequency (f) enabling echoes to rise sharply at an end face of the tube are obtained beforehand. An A scope S' represents this state. A welded bonded part of a plastic tube to be inspected is placed in the same positional relation, and inspected by the ultrasonic flaw detection element having the angle of refraction θ and pulse frequency (f). The A scope S' is displayed.  The presence/absence of an internal defect is judged from the presence/absence of echoes in a time t0 , and moreover seriousness of the defect can be detected from a sharpens of the rise of echoes.

Title: Lighting fixture device
Inventor: HORII YASUAKI
IPC: F21S2/00
Filed: 1995-03-08
Abstract: PURPOSE:To form cut lines of light distribution clearly. CONSTITUTION:A lighting fixture device is composed as a front lamp for a vehicle. Light from a light source is transmitted by an optical fiber 30. The light goes through a shade 60 to be formed in a specified form to get from the optical fiber 30 into a light guide lens 20. The light guide lens 20 converges the light from an incidental end surface 22 at an outgoing end surface 21 to radiate it. Light distribution is thus formed in accordance with the form of the shade 60 and optical characteristics of the light guide lens 20. An end part of the shade 60 decides a cut line at an upper part of the light distribution, especially in an opposed traffic lane direction. This shade 60 is positioned on an optical axis X' of the outgoing end surface 21 of the light guide lens 20. The upper cut line of the light distribution in the opposed traffic line is thus formed clearly, thereby a wide radiation range reaching an opposed traffic line can be realized without giving glaringness to a driver in the opposed traffic lane.
