Title: Camera for optical extensometer
Inventor: YAMADA YOICHI
IPC: G01B11/16
Filed: 1990-01-31
Abstract: PURPOSE:To measure continuously the extension of a test piece by providing a slit plate for regulating the light from an illuminating optical system so that the illuminating area on the test piece is generally agreed with the view field of a photoelectric converting device on the test piece. CONSTITUTION:A belt-shaped light 11 dispersed in the form of a belt by a cylindrical lens 3 assumes the coaxial elliptical luminance distribution since a semiconductor laser 2 is used as a light source. When the belt-shaped light 11 is irradiated to an index mark MK as it is, an image edge on a photoelectric converting device 8 is turned not to be sharp, and therefore such a slit 12 that allows only a part of the belt-shaped light 11 having the generally uniform luminance distribution to pass through is used. In order to adjust the optical axis of this camera 1 for optical extensometer, the waveform of a low level of the device 8 indicating the mark MK is arranged to be at the center of the device 8 while the output waveform is monitored by an oscilloscope. According to the camera 1, it is possible to easily set the illuminating area at the center on the mark MK of a test piece TP and it is positively prevented that the viewfield goes beyond the mark MK as the test piece TP becomes thin during the test.

Abstract: PURPOSE:To make possible an effective air escape at the time of resin sealing and to contrive the realization of a favorable resin sealing by providing air vent grooves at positions to oppose to die pad parts on the surface of at least one way of the surface and the back surface of an outer frame. CONSTITUTION:A lead frame 1 is interposed between top and bottom forces 10a and 10b of a metal mold 10 for resin sealing and air escape grooves are respectively formed of these top and bottom forces 10a and 10b and air vent grooves 9a and 9b provided in an outer frame 6 of the lead frame 1. In this state, when a fused thermosetting resin is pressed into a cavity formed in the matching surface of the top and bottom forces 10a and 10b of the metal mold 10, the air in the cavity is exhausted from the air vent grooves 9a and 9b. After that, the interior of the cavity is filled with the resin and part of the resin intrudes into the air vent grooves 9a and 9b. At this time, as a positioning hole 7 is closely readysealed with its peripheral part 8 and the top and bottom forces 10a and 10b, the positioning hole is prevented the resin from intruding. Thereby, even when the resin intrudes into the air vent grooves 9a and 9b, to adhere on the metal mold is eliminated.
