Abstract: In a production apparatus (1), after rear holders (7a, 7b) and a housing body (8) are molded by molding die cavities, slides (11a, 11b) are moved apart from the housing body (8). Then, cylinders (16a, 16b) are driven to move the rear holders (7a, 7b), holders (13a, 13b) and the slides (11a, 11b) together with slide plates (14a, 14b), so that the rear holders (7a, 7b) are located in opposed relation to the housing body (8). Then, cylinders (19a, 19b) are driven to move the rear holders (7a, 7b) toward the housing body (8), thereby provisionally retaining the rear holders (7a, 7b) on the housing body (8). Therefore, the amount of movement of the slides (11a, 11b) is small, and it is not necessary to provide any space for holding the slides (11a, 11b), moved into their respective stand-by positions, and therefore the small-size design of the production apparatus can be achieved, and also the production efficiency can be enhanced.

Abstract: Stranded cable conductors, especially their connecting joints with electrical components, are damaged during use in aggressive surroundings, for example in fuels. Protective measures, such as shrinkable tubes or protective coatings, do not ensure adequate protection however. With the novel process, stranded cable conductors and their connecting joints with electrical components are to be protected against the attack of aggressive media. With the process according to the invention, stranded cable conductors are encapsulated in a fuel-resistant plastic, the encapsulation not covering the entire length of the stranded cable conductor but the region which is exposed to aggressive media. The process does not require any pretreatment of the stranded cable conductors.

Uninterrupted ring ridges below the collar assure a positive seal.

Abstract: This invention relates to a method of manufacturing an ultrasonic transducer. First, a plurality of printed boards in each of which a plurality of leads are formed in a line are stacked. The end portions of the leads protrude from each printed board. These lead end portions are inserted into a plurality of lead holes of an alignment jig. The plurality of printed boards are buried in the back surface of this alignment jig, and a backing layer is formed by resin molding. After that, the alignment jig is removed from the surface of the backing layer, and the surface of the backing layer is flattened. Since the end portions of the leads are exposed to this flattened surface of the backing layer, discrete electrodes formed on the back surfaces of transducer elements are electrically connected to these lead end portions. The accuracy of lead arrangement is thus improved by the use of the alignment jig. This reduces alignment errors of leads with respect to the discrete electrodes of the transducer elements.

Abstract: A group of upper side male terminal fittings 2A and lower side male terminal fittings 2B are secured to the upper and lower surfaces of a mount plate 8 formed as a separate piece by pressing projections 12 into mount holes 16, thereby forming a core member 7. A housing 1 is formed by insert molding using this core member 7 as a core material. Since insert molding can be performed with the outer surfaces of the male terminal fittings 2A, 2B opposite from those secured to the mount plate 8 exposed, only the thickness of the housing 1 is added at the outer surfaces of the male terminal fittings 2A, 2B. Thus, there can be obtained a connector having a small thickness T around the male terminal fittings 2A, 2B.
