Abstract: A vehicle circuit panel is provided that includes a base member formed of an electrically insulating plastic material and a conducting plastic circuit path formed of an electrically conducting plastic material. The conducting plastic circuit path is formed unitarily with the base member, and is at least partially embedded in the base member, thereby forming a one-piece molded plastic member. Thus, the conducting plastic circuit path is formed into a desired circuit configuration within the base member. With the above construction, the conducting plastic circuit path can be formed into any circuit configuration, thereby increasing the degree of freedom of design of the arrangement of the circuit path.

Abstract: A clamp is provided and is commonly usable for brackets having different thicknesses. The clamp 10 includes a base plate 11 to be fixed to an automotive wiring harness by taping and a box portion 12 integrally formed with the base plate 11, and an arm 13 having a lock claw 13a at its leading end projects from a rear part of the lower inner surface of the box portion 12 into a hollow portion 14 of the box portion 12. A bracket 4 projecting from a vehicle body is inserted into the hollow portion 14 of the box portion 12 and the lock claw 13a is inserted into a hole 4c formed in the bracket 4 to lock the bracket 4 and the clamp 10. Thinned and elastically deformed thickness take-up portions 15 are formed at the opposite side walls of the box portion 12. In the case that the bracket 4 being inserted into the hollow portion 14 of the box portion 12 is thick, the thickness take-up portions 15 extend to enable the insertion of the lock claw 13a into the hole 4c of the bracket 4.

Abstract: A boot 23a for insulating the bare end of an insulated electrical wire includes a neck 25 to hold a wire or wires 21a centrally in the boot. The boot is filled with a solidifiable liquid substance 24, such as epoxy resin, to encapsulate the wire or wires after insertion. The boot may be transparent and include depth markings 26, 27 to determine the minimum insertion depth of the wire or wires 21a and the minimum level of substance.

Abstract: An admixture for cement compositions containing tetrahydroborate, and cement composition containing a tetrahydroborate admixture made of salt borohydride, cement, aggregate and water. Since tetrahydroborate has the expansion effect hardly influenced by temperature, expansion amount is easily controlled. Since cells generated by foaming are fine, a hardened body with the excellent resistance to freezing and thawing can be obtained.

Abstract: An oxygen absorbing sheet is disclosed, which is obtained by molding a resin composition comprising from 15 to 70% by weight of a thermoplastic resin and from 30 to 85% by weight of an oxygen absorbent into a sheet having a thickness of from 10 .mu.m to 5 mm and stretching the sheet at least uniaxially at a stretch ratio of from 1.5 to 8.0. The oxygen absorbing sheet is easy to handle, and its oxygen absorption capacity is arbitrarily controllable.

Abstract: The invention relates to a hydraulic cement composition comprising, as a carbonation inhibitor of the cement composition, at least one compound of the formula (I):A--(Y.sub.n --H).sub.lwherein A is a polyamine residue containing 2-10 carbon atoms,Y is --C.sub.3 H.sub.6 --O--,l is a number equal to 1-8,n is a number equal to 1-4,the product of n.times.l is equal to 13-20,the active hydrogen(s) involved in the amino groups in the polyamine residue being partly or wholly substituted with the residue(s) of propylene oxide.

Abstract: An actuator used shape memory alloy and a display conversion device of signs characterized in that, in the actuator equipped with a shape memory alloy allowing a movable body to work in one direction by the restoration force to the memorized shape at the time of temperature rising, a control base standing opposite to at least part of said movable body is provided, concave portions are provided to one of said movable body and control base and, at the same time, a control element is provided to the other thereof to guide said control element to said concave portion and to press said concave portion and control element against one another by a fixed resilience.

Abstract: In a metal material having a surface adapted to slide on a surface having a nickel-silicon carbide composite electroplated layer and subjected to a treatment for causing silicon carbide particles to project outward beyond the surface, the surface of the metal material is provided with porous hard chrome plating, whereby a lubricant may be deposited and retained in the porous plated layer.
