Title: Plating method for inside wall of heat transmission pipe
Inventor: INATANI MASATOSHI
IPC: F28D15/02
Filed: 1985-05-24
Abstract: PURPOSE:To form a metallic plating layer having adequate dendrite ruggedness on the inside wall of a heat transmission pipe by using the wall surface of said pipe as a cathode side and pouring a plating liquid prepd. by adding an oxyethylene surface active agent and a low concn. of chloride as an additive to said liquid into the heat transmission pipe thereby plating the inside wall thereof. CONSTITUTION:The heat transmission pipe 10 and fins 3 are tentatively fitted to each other in a prescribed position. The pipe 10 and the fins 3 are press welded and fixed by expanding the pipe 10. The pipe 10, a connecting pipe 11 and a circulating pump 12 are then combined and the acidic copper sulfate plating liquid 9 added with the oxyethylene surface active agent and a low concn. of chloride in a plating cell 7 is circulated toward the side A in the pipe 10. Negative electric charge is thereupon applied to a counter electrode 15 of an iron bar from a DC power source and said electrode is used as the cathode side. Positive electric charge is applied to a connecting terminal 16 as the anode side. Since the terminal 16 and the pipe 10 conduct to each other, the pipe 10 has the positive charge and the inside wall of the pipe 10 is plated.

Filed: 1977-09-19
Abstract: PURPOSE: A syntactic foam having a low specific gravity, improved mechanical property, and uniformity, prepared by dispensing hollow spheres homogeneously in a thermosetting resin containing a thermoplastic resin.  
     CONSTITUTION: A syntactic foam is obtained from (A) a resin blend of a thermosetting resin and a thermoplastic resin, and (B) hollow spheres having a particle size of preferably 5W500μ by the vacuum impregnation or mixing method. The addition of the thermoplastic resin by the mixing method permits the foam having almost the same specific gravity as that obtained from thermosetting resin alone by the vacuum impregnation method. The vacuum impregnation of the resin blend gives a foam having a specific gravity about 0.1W0.2 lower than the thermosetting resin alone. If a long time is required for molding, e.g. vacuum impregnation, a combination of (a) a prepolymer having ester linkages and double bonds in the molecule and (b) a thermosetting resin consisting of a radically polymerizable monomer compatible with the prepolymer, and (c) a (co) polymer of styrene, an alkyl (meth) acrylate, etc. is preferred.

Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a distribution board shutting off the power supply, when the vector sum of the current flowing in two voltage lines of a single-phase three-wire system distribution line exceeds the contracted current. SOLUTION: A master switch 3 forcibly opens a contact 8, when one of the currents flowing in voltage lines L0, L1 of a single-phase three-line system distribution line goes beyond the first threshold (the rated current). In a vector sum detector 6, a current detecting part 15 detects the currents respectively flowing in the voltage lines L0, L1 according to the output from a current transformer 14. A CPU 11 calculates the vector sum of the currents flowing in the two voltage lines L0, L1 according to the result detected by the current detecting part 15. When the vector sum exceeds a second threshold (the contract current), the CPU 11 outputs an output signal, and an output circuit 19 drives a relay 20 based on the output signal from the CPU 11 to output a trip signal to the master switch 3. Thus, the master switch 3 forcibly opens the contact 8 according to the trip signal.
