Further, the emboss pattern that a recessed square spindle pattern having the slope angle of beta = 45 deg. is repeated at the pitch of p = 0.1 - 1.5mm, on the whole of an inclined surface. Therefore, the light made incident on the transparent light leading plate from a light incident surface is scattered on a part having the emboss pattern, its advancing direction is changed, and it is transmitted toward a liquid crystal display panel. Further, the thickness of the transparent light leading plate is gradually reduced as it is far from the light incident surface, so that the ratio that incident light reaches the light diffusing member is increased, and the use efficiency of the incident light is increased.

IPC: B23K31/00
Filed: 1989-10-06
Abstract: PURPOSE:To easily estimate the depth of penetration of the welded zone to which an ultrasonic measuring method is hardly applied without destruction by placing the welded zone in a magnetic field established by a coil and measuring the inductance of the coil which is generated with magnetic flux passing between base materials of the welded zone. CONSTITUTION:A welded metallic pipe 1 (fixed core) as a component of a solenoid valve for a hydraulic pressure circuit is in sandwich structure which has a part 1B of stainless steel as a substantially nonmagnetic body sandwiched between parts 1A of carbon steel as a ferromagnetic body. Then the welded zone 2 of the metallic pipe 1 to be inspected is placed in a measuring coil 3 and while the pipe 1 is fixed, the inductance of the coil 3 which is generated with the magnetic flux passing between the base materials 1A and 1B of the welded zone 2 is measured. Thus, even when a different kind of material is welded, the weld part 2 where the base materials are fused mutually is less in magnetic resistance than an unfused groove part 10 and the larger the depth of penetration, the larger the quantity of passing magnetic flux, so the measured impedance is used to estimate the depth of penetration by using a specific expression.
