Abstract: PURPOSE:To eliminate the necessity of correction of positions, to decrease defective assembling, and to improve the quality of a semiconductor, by using an intermediate jig in setting jigs for positioning a shaping solder or a semiconductor element. CONSTITUTION:For mounting of a semiconductor element 4 and an inside electrode frame 5, or the semiconductor element 4 and a conductive plate 3, the inside electrode frame 5 connecting the semiconductor 4 and each terminal of a case equipped with three terminals is put in a jig with stone 10. Then, an intermediate jig for positioning 9 is set to the jig with stone 10. Following this, each shaping solder 8 as a junction member and each semiconductor element 4 are put in the electrode frame one after another by hand. When these procedures are completed, the intermediate jig is taken out, and it is mounted on the part between the semiconductor element 4 and a base plate 1. In addition, a conductive plate 3 to be connected is set and assembled by had. Therefore, a defect of excess soldering due to off-position, or an assembling defect of short circuit of a gate T1 electrode in the semiconductor element 4 is reduced. In addition, characteristic inferiority is also reduced. As a result, the quality of the semiconductor can be improved.

Title: Testing method for deterioration acceleration of concrete
Inventor: KIDA DAIZO
IPC: G01N33/38
Filed: 1990-05-14
Abstract: PURPOSE:To obtain a sufficient acceleration extent by dipping the concrete to be tested in an electrolyte, installing a couple of electrode on both sides of the concrete, and applying a DC voltage between those electrodes and dissolving calcium ions out of the concrete in the electrolyte. CONSTITUTION:The couple of electrode plates B and D are provided opposite the exposed surfaces of the body X to be tested; and one electrode plate B is connected to the positive electrode side of a DC power source E, and the other electrode D is connected to the negative electrode side of the DC power source E. When the DC voltage is applied between the electrodes B and D, an electric field is produced in the electrolyte where the concrete is dipped and calcium ions in the concrete are charged electrostatically to the positive polarity, so they are attracted to the negative electrode side and dissolved out in the electrolyte. The current dissolving-out extent is almost proportional to the DC voltage between the electrodes, so the extent of the dissolution of the calcium ions, i.e. the acceleration of the test can easily be varied by adjusting the level of the DC voltage between the electrodes.

IPC: G01B11/06
Filed: 1981-08-04
Abstract: PURPOSE:To reduce a measurement error caused by a variation of a distance between an optical system and an object to be measured, by scanning an image by a rotary mirror provided to a focus of a lens provided to an optical path,  and deriving an arithmetical mean of a time differnce of impulsive signals generated by reflected images of both front and rear side. CONSTITUTION:For instance, spot light from an He-Ne laser light source 2 becomes sharp slit light on a curved surface transparent body for measuring thickness, for instance, a TV panel 1, by a cylindrical lens 7. In this way, since incident light is converted to a slit shape, unstabilization of a measured value due to a fine uneven inside surface of the panel 1 is solved. Length and width of this slit light are selected in accordance with an area to which it is desired to  average a measurement, the slit-like incident light is separated into 2 directions by a beam splitter 8, and is reflected by half-mirrors 9, 9' so as to be irradiated from symmetrical directions against a thickness measuring part of the TV panel 1.
