Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain better characteristics of a solder alloy whose main component is tin by making a zinc stick to a copper sheet, and making a tin solder alloy which coats a zinc layer stick to it. SOLUTION: A Cu substrate is submerged in Zn at suitably distance away from an appropriate anode. With the anode supplied with a current, a salt of Zn is cathode-reduced to a metal, so that a solder alloy is stuck to a circuit board. The sheet is taken out of a plating bath, and in order to minimize contamination, a plated conductive sheet is entirely washed as soon as possible. An Sn-Bi solder alloy is stuck on a Zn layer. Thereby, a sufficiently low melting point is provided for avoiding damages to a part of PCB and degrading conduction characteristics of the circuit board.

Title: Method for regulating coating weight in continuous hot dipping of steel sheet
Inventor: ISHII TOSHIO
IPC: C23C2/14
Filed: 1988-04-28
Abstract: PURPOSE:To regulate the coating weight of thin coating and also to prevent the occurrence of surface contamination due to splashes, etc., by pushing vibrating plates vibrating with ultrasonic frequency against the plated surfaces of a steel sheet, respectively. CONSTITUTION:Ultrasonic vibrators 2 are disposed on both sides of a continuously hot dipped steel sheet 1.

Title: Oil-filled electrical apparatus having oil leakage preventing device
Inventor: NAKATSUHARA NOBORU
IPC: H01F27/40
Filed: 1981-07-09
Abstract: PURPOSE:To prevent oil from leaking through packing by balancing oil pressure applied to packing of a flange bonding section with atmospheric pressure. CONSTITUTION:When oil pressure applies to packing of a flange section 2E and insulating oil in a body tank 2 is easy to leak outward, a contact for an upper control level L1 of an oil gauge 11 closes and an electromagnetic valve 19 opens to actuate a vacuum pump 21. This actuation exhausts the air in a conservator 6 outward, depressing the oil level in a control tank 10 to the reference oil level, and reducing oil pressure applied to packing of a tank 2 to balance with atmospheric pressure. With this oil level lowered, the contact for the oil level L1 opens. Next, when an oil temperature rises, the oil level in the tank 10 goes up from L0 to L1 and a balance state at the packing can be recovered by the operation of a pump 15. When an oil temperature drops, on the other hand, the oil level in the tank 10 lowers from L0 to L2. Then, the contact for the oil L0 closes and an electromagnetic valve 18 opens, thus air is inhaled from a breather 20 to the conservator 6.

Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To effectively accept the requests from plural users at a time or almost at a time by using the idle ones of plural receiving parts and then accepting a lending or returning request at every receiving part. SOLUTION: A receiving part A consists of three receiving areas A1, A2 and A3 which can accept both lending and returning requests and are located at the right and left sides and the center parts respectively of a cabinet front face. Thus, the users can use the idle receiving areas and accordingly are not kept waiting so frequently for using the part A despite the concentration of users. Furthermore, the users are not kept waiting so frequently for using the part A even when the lending or returning requests are concentrically accepted since each of areas A1 to A3 can accept a lending or returning request. As a result, the requests of users can be effectively accepted.
