Title: Printed board
Inventor: SAKAMI SEIJI
IPC: H05K3/34
Filed: 1992-05-26
Abstract: PURPOSE:To uniform the heights of solder precoated parts formed on electrodes by forming dummy electrodes outside the electrodes at the ends of a plurality of electrodes formed on a board. CONSTITUTION:A plurality of electrodes 3 of a circuit pattern of conductive metal are formed on a surface of a board 2, and dummy electrodes 6 are formed outside the electrodes 3 at both ends. When the board 2 is dipped in plating solution 11, metallic ions in the solution 11 are attracted to the surfaces of the electrodes, and precipitated to form a solder precoated part 4. In this case, since the volume W2 where the ions to be attracted to the electrodes 6 exist is wider than the volume W1 where the metallic ions to be attracted to the electrodes 3 exist, a large amount of the ions are precipitated on the electrodes 6, and the heights of the precoated parts 4a become higher than those of precoated parts 4b on the electrodes 3. However, since no leads of an electronic component are connected to the electrodes 6, the heights of the precoated parts can be made uniform.

Title: Cooling mold for pulling-up continuous casting
Inventor: FURUTA MASAO
IPC: B22D11/043
Filed: 1992-05-26
Abstract: PURPOSE:To provide the uniform cooling capacity for the sleeve in the inner circumference and to prevent the uneven wall thickness of cast tubes by reducing the sectional area of the passage downstream of the inner circumferential annular passage of a cooling jacket. CONSTITUTION:In an inner circumferential annular passage 24 of a cooling jacket 2 of a cooling mold, the inner edge of an annular covering plate 8 is extended to the inner side in the vicinity of a discharge port 4, and the sectional area of the passage at the downstream end of the inner circumferential annular passage 24 is reduced. This cooling mold is dipped in the molten metal. The molten metal invaded into the sleeve 1 from the lower opening of the mold is brought into contact with the sleeve 1, cooled and solidified. The solidified layer is intermittently pulled up to form a tube body. Since the passage is reduced at the downstream end of the inner circumferential passage 24, the turbulence of the cooling water is not affected in the inner circumferential annular passage 24 even when the flow of the cooling water is disturbed in the passage ranging from the downstream end of the inner circumferential annular passage 24 to the discharge port 4. The cooling water in the inner circumferential annular passage 24 flows as the axially symmetric rotational flow at an approximately uniform speed, resulting in the uniform cooling capacity for the sleeve 1 in the circumferential direction.

Title: Temperature difference battery
Inventor: IKESHOJI TAMIO
IPC: H01M10/39
Filed: 1985-06-19
Abstract: PURPOSE:To suppress increase in internal resistance by placing one or more electrodes inside an electrolyte between two electrochemical electrodes in parallel to the electrodes. CONSTITUTION:Electrolytes are partitioned to four layers 12, 13, 14, and 15 by electrodes 9, 10, and 11 placed in parallel to electrochemical electrodes 7, 8 having different temperature. If the heat resistance and electric resistance of electrodes 9-11 are negligible, and when the total thickness of electrolytes 12-15 is equal to the thickness of an electrolyte 1 of the conventional temperature difference battery, the internal resistance is generally the same. In this temperature difference battery, concentration gradient in the inside of electrolytes 12-15 is widened. By partitioning electrolytes by the electrodes, limiting current density is increased and nonlinear increase in internal resistance is suppressed.
