Abstract: PROBLEM TO BE SOLVED: To ensure the long-period reliability of the strength of a solder by a method wherein means for making a substrate slide in a direction vertical to the board thickness according to the expansion and contraction of the substrate due to a thermal variation in the periphery of the substrate in a state that the substrate is held in the direction of the board thickness are provided in the part of the substrate which is positioned on the opposite side to a connector. SOLUTION: Screws 2, which are respectively inserted in holes 4 positioned in the side of a coaxial connector 6 and are used as fixing means, and screws 2, which are respectively inserted in holes 4 positioned on the opposite side to the connector 6 via washers 11, are respectively made to engage with threaded holes 9 to fix a substrate 1 in an enclosure 3.  In this state, when the substrate 1 and the enclosure 3 are thermally expanded and contracted by a temperature change, a stress due to a fifference between the amounts of expansion and contraction of the substrate 1 and the enclosure 3 due to the linear expansion coefficients of the substrate 1 and the enclosure 3 makes the substrate 1 slide horizontally between the enclosure 3 and the washers 11, that is, makes the substrate 1 slide perpendicularly to the board thickness of the substrate to contrive to make the difference between the amounts of expansion and contraction relax. Thereby, the stress does not act on the soldered parts of lands 5 to lead terminals 7, the deterioration of the strength of a solder can be prevented and the long-period reliability of the strength of the solder can be ensured.

Filed: 1978-03-23
Abstract: PURPOSE: To accomplish the dynamic scatter mode display and the color display thereby to make it possible to improve the dispalying function by adding both a dichroic dye having a guest-host effect and a conductivity applying agent to a nematic liquid crystal which has a negative dielectric anisotropy.  
     CONSTITUTION: There are added to a nematic liquid crystal 1-(p-nonyloxyphenil amino)4-hydroxyanthraquinone as a dichroic dye and a TCNQ as a conductivity applying agent. A curve A indicates the relationship between a dielectric constant- voltage when an AC voltage of 60 Hz is applied. A curve B indicates a similar relationship when an AC voltage of 1 KHz is applied. As shown, the dielectric constant is stepwise varied by the guest-host effect with the application of 9 volts thereby to display a color. If the voltage is raised to 18 volts, the secondary stepwise change in the transmissivity takes place so that the display is accomplished by the DSM phenomena. By varying the voltage applied for the same liquid crystal layer, the color display and the DSM display resorting to the guest-host effect are accomplished so that the display effects of the liquid crystal display device can be improved.

Abstract: PURPOSE:To securely embed an engaging protrusion of a handle at the utmost part of a recess making it hard to be drawn out and further making the handle easy to grasp from slantly upward by a method wherein the handle is made into an approximate U-shape and the handle is engaged with a bottle wall at the deep part of a vertical face as well as a vertical cross-sectional shape is made in an approximate L-shape. CONSTITUTION:At the utmost part of a vertical face of a recess 2 formed on an upper side wall of a bottle 1, engaging protrusions 42, 43 of a handle 3 are embedded into a bottle wall part. Since the utmost part is thick and easy to mold, it permits the engaging protrusions 42, 43 to be securely embedded. At this time by making a cross-section of the recess 2 in an approximate L- shape, drawing factor on the upper surface of the recess 2 is decreased. Accordingly the degree that the bottle wall part with the engaging member 42 embedded is extended from its periphery by drawing at the time of blow-molding is decreased, thereby permitting the engaging protrusion to be securely embedded as a result. Then since the vertical cross section of the recess 2 is in an approximate L-shape, the handle can be grasped from slantly upward.
