Abstract: An electrical terminal for use with a resin-made connector housing containing a locking lance, consists of a terminal body having a collar projecting circumferentially therearound, and a locking member separate from the terminal body. The locking member has engagement means engageable with the collar to retain the locking member longitudinally in place on the terminal body. The locking member engages with the locking lance to lock the terminal in the connector housing. The locking member is made of resin so that during moving the terminal into and out of the connector housing, resin is prevented from being shaved off from the connector housing including the locking lance.

Abstract: In the contact probe 1 having an array of leads 3 densely attached to a surface of an insulative film 2, pressure contact ends are formed by one end of the leads 3 being arranged in an array along one end edge portion of the insulative film 3. Slots are formed in the one end edge portion of the insulative film 2 such that the slots 9 are open between adjacent contact ends. When the lead ends arranged in the array on the surface of the insulative film are contacted under pressure with a given electronic part, a sufficient degree of freedom of flexure of the contact ends is obtained, so that the contact ends are contacted under pressure with the external terminals of the electronic part.

Abstract: A ceramic porous body has a layered structure including a plurality of foam-like ceramic layers. The foam-like ceramic layers are formed by firing foam-like ceramic shaped layers each having a thickness of not more than 5 mm. The adjacent shaped layers are joined directly, or bonded via a thin foam-like ceramic layer or dense ceramic layer.

Abstract: A ceramic porous body is constituted of ceramic particles which have a substantially continuous, monotonic size distribution in the thickness direction of the porous body.

Abstract: One of a pair of mating electrical connectors A, B has a cam groove 2 and a coupling lever C pivotally attached to the one connector. The coupling lever C has an operation portion 3 provided with a locking engagement portion 4 and a pair of lock-guiding portions 11 positioned at opposite sides of the locking engagement portion 4. The other one of the connectors has a driving pin 5 for advancing into the cam groove 2 and a lock portion 7. When the pair of connectors A, B engage with each other by operating the coupling lever C, the locking engagement portion 4 slidably engages the lock portion 7 so that the center line of the locking engagement portion 4 is urged toward the center line of the lock portion 7.

Abstract: A connector-coupling lever is mounted to the corresponding connector housing according to the following steps. The windings of a spring engage with a supporting shaft extending from a side wall of a connector housing, and one end of the spring is fixed to a locking portion of the side wall. The other end of the spring engages with a provisional locking channel by way of an insertion channel, wherein both the insertion channel elongated along the side wall of the connector housing and the provisional locking channel extending in the direction away from the side wall are provided in a provisional locking portion attached to the connector housing. A bearing hole formed in a side arm of the connector-coupling lever engages with the supporting shaft.

Abstract: A lever-type connector in which the need for a resilient member is obviated, thereby saving cost, and including engagement portions are less liable to damage or to deterioration due to aging when a large impact force is accidentally applied, this impact force can be effectively relieved, thereby preventing damage to the engagement portions. The lever-type connector includes a pair of female and male connectors. Engagement shafts are formed on the male connector, and a retaining lever, having fitting grooves, is mounted on the female connector for pivotal movement about support shafts. When the retaining lever is pivotally moved, the engagement shafts are forcibly moved through the fitting grooves, thereby fitting the male connector into the female connector.

Rail portions are arranged on a front surface of the lever, each rail portion having a predetermined surface of curvature. When the male connector is inserted into the female connector, shaft portions of the fixing shafts are abutted against the rail portions and bias the rail portions, so that the surfaces of curvature produce resisting forces, each having a component for pivoting they lever.

Abstract: A metal cord for reinforcing a rubber article is made by twisting three or more metal filaments. At least one or at most the total number minus two of the metal filaments have a larger shaping ratio in the diametrical direction of the cord than the other metal filaments. At least one of the metal filaments having a larger shaping ratio is kept out of contact at portions in the longitudinal direction with a metal filament or filaments arranged in juxtaposition at one side or both sides thereof. At least two adjacent ones of the metal filaments having a smaller shaping ratio are in contact with each other.

A ceramic membrane having a smaller pore size and serving as a filter membrane is formed on the exposed surface of the bone-like member and the surfaces of the struts of the network member by a ceramic-slurry foaming technique.

Abstract: A metal cord is formed by twisting two spirally preshaped metal filaments together with a twisting pitch P. The metal filament has not only the spiral shape formed by twisting, but retains so much of its spiral preshape as to have a pitch p equal to 0.20-0.50 times the twisting pitch and a diametric height h of 0.05-0.25 mm. The retained spiral shape is in the same rotary direction as the direction in which the filaments are twisted together.

Abstract: A steel cord for reinforcing rubber. It is made of three steel filaments all having different diameters from one another. The small-diameter and medium-diameter ones of the three filaments have internal stresses adapted to be released when the cord is cut at both ends thereof. Owing to these stresses, the diameter of the cord is adapted to increase after it is cut at both ends. At the same time, the medium-diameter and small-diameter filaments retract inwardly from the ends of the large-diameter and medium-diameter ones, respectively.
