IPC: B23K1/00
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To easily measure the influence of the activity deteriorating every moment of a flux by supplying a solder and the flux onto a substrate followed by soldering, and successively moving the fused solder and flux to a non-soldered land. SOLUTION: A temperature controller 33 is connected to a power source and set to soldering temperature. When a block-like solder lever 30 reaches a prescribed temperature, the horizontal moving speed of a substrate slider 6 is set by a horizontal moving speed controller 34, and a start button 34' is pressed. Then, the solder lever 30 makes contact with a solder paste 40 to fuse the solder and successively moves the fused solder and a flux on a comb- shaped copper land 7'. Therefore, the comb-shaped copper land 7' is successively wetted by the solder. When the flux activity is lost by thermal deterioration, the following copper land is never wetted. Accordingly, the wetted range is visually measured, whereby the activity duration of the flux can be easily measured.

Title: Negative electrode for battery
Inventor: OMOTE KAZUYUKI
IPC: H01M4/74
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To provide an electrode having a high discharge characteristic and a low electric resistance by constituting an electrode substrate of a copper mesh material or a copper mesh material applied with nickel plating. SOLUTION: By replacing a nickel mesh material with a copper mesh material in a negative electrode plate 16 integrated with a sintered hydrogen storage alloy 11, the electric resistance reduces from 0.64 mΩ.cm to 0.16 mΩ.cm. The soft mesh material is depressed at the time of welding the plate 16 to a tab 12, thereby the welding area to the tab 12 is made large, resulting in making the electric resistance of this part low. No elusion of copper into an electrolyte occurs when the potential of copper is not more than -0.4 V even if charge and discharge are repeated when applied to a battery. With the application of nickel plating of 1-2 μm thickness of the plate 16, copper of the copper mesh material does not elude in the electrolyte. Since the surface layers of the tab 12 and the copper mesh material are of same kind nickel, the welding is made stable, and the nickel layer at the welding portion is fused partially by the heat of welding, thereby enlarging the welding area for making the electric resistance low.

Abstract: PURPOSE:To exactly transmit a message in one's absence by automatically reproducing a preliminarily recorded message by calling a telephone set at the time of a reproduction start time. CONSTITUTION:At the time of reproducing the message recorded in a tape recorder 7, a time counted by a timer 8 reaches the reproduction start time, and then a time signal is transmitted to a control part 2 and a calling part 9. The calling part 9 calls a telephone set 1, and rings a calling sound. When an off-hook detecting part 5 detects that the telephone set 1 is picked up, and an off-hook is obtained, an off-hook detection signal is transmitted to the control part 2. When the time signal of the reproduction start and the off-hook detecting signal are successively transmitted to the control part 2, the control part 2 judges it to be the reproduction start, and transmits a reproduction signal to the tape recorder 7 after a fixed time since receiving the off-hook detection signal. Then, the tape recorder 7 receives the reproduction signal, starts the reproduction of the message, and transmits the message from the telephone set 1.
