IPC: H01G13/00
Filed: 1987-01-14
Abstract: PURPOSE:To make it possible to uniformly line up the tip parts of the lead led out from the main body of parts at fixed pitch intervals by maintaining the tip parts in the state as they are by a method wherein the base end part of the lead is pressed in the desired direction in the state wherein the tip part of the lead of an electronic part is fixedly retained and the bending operation of the lead is performed. CONSTITUTION:A bending metal mold consists of the upper and the lower metal molds with which the main body of an electronic part 1 is retained, and the lower jig 11b retains not only the part main body 2 but also the base end part of a lead 3 from the lower part. The tip part of the lead 3 is clamped by pinching it from the upper and the lower sides with the upper and the lower jigs 10a and 10b of a fixed jig 10, and from the above-mentioned state, the lead 3 is bent by rotating a bending metal mold 11 at 90 deg. with the bending point 0 of the lead 3 as the center point while the part main body 2 and the base end part of the lead 3 are being pressed by the lower metal mold 11b. As a result, no irregularity in pitch interval of the lead tip part after the lead has been bent is generated, and no poor insertion and fixing of the lead can take place.

Filed: 1986-01-14
Abstract: PURPOSE:To enable comparison between a theoretical value and a measured data, by measuring sensitivity after a rise in the temperature of a detector itself caused by heat due to a bias current is offset. CONSTITUTION:In the evaluation of sensitivity of a photoconductive type infrared detector with a large heat generation by a bias current, a means for adjusting the temperature of a detector holder is provided and the maximum of an output is read from a data obtained with the output of the detector at a several bias current values as function of temperature of a detector holder and are plotted as functions of bias currents to correct the effect of the heat generation. In other words, in order to correct the effect of the heat generation, it is necessary to offset a rise in the temperature of the detector itself by setting the temperature of the detector holder at a low temperature. The responsivity as obtained when the temperature of the detector holder is lowered step by step reaches the maximum at a certain temperature. This measurement is conducted for several bias currents and the maximums of the response are plotted with respect to the bias currents to obtain a data for the dependence of response on bias current with a corrected effect of the heat generation.

The shadow forms an image through an image forming lens 4 provided after the object 3 and the size of the image can be measured by photoelectric photometry. In addition, the outside diameter of the object 3 can be calculated from the measured results.  Therefore, the measurement error caused by the nonlinear refraction of incident light in the periphery of the object 3 can be reduced.
