Title: Method for refining bismuth
Inventor: BABA KOZO
IPC: C22B30/06
Filed: 1987-04-24
Abstract: PURPOSE:To improve the recovery rate of a bismuth product, by separating metal of high bismuth content from a bismuth-containing sediment in a furnace, by refining the above metal in a refining furnace, and by circulating the residue between a liquation furnace and the refining furnace. CONSTITUTION:A bismuth-containing sediment produced in a copper- or lead- refining stage is separated into metal containing large amounts of bismuth and white metal in a furnace. The metal is refined in a refining furnace into a bismuth product, and dross is fed into a liquation furnace. The white metal previously separated in the furnace and reduced in bismuth content is fed into the liquation furnace and heated together with the dross at 400-600 deg.C for 3-8hr. Then, eluted liquated metal containing high-concentration bismuth is returned again to the refining furnace to undergo refining.

Title: Dc/dc converter
Inventor: SAGANE TOMIYASU
IPC: H02M3/28
Filed: 1991-05-07
Abstract: PURPOSE:To control the increase of a current at turn-off and the increase of voltage at turn-off by connecting a current control circuit, which controls the current at turn-off of a switching element, and a vibration control circuit, which controls the vibration at turn-off, between the switching element and a transformer. CONSTITUTION:The increase of a turn-off current at the time of a transistor becoming on is controlled with the coil L2 of a current control circuit 11, and is further controlled with the parallel circuit of a diode D3 and a resistor R2. Especially, the diode D3 has a function of hindering the surge current at switching of the transistor TR from going through to the side of a coil L2 from the transistor TR. Next, the vibration control circuit 12 by a diode 4 and a resistor R1 hinders the ringing at the time of the transistor TR being turned off. This way, the increase of the current at turn-off or the increase of voltage at turn-off can be controlled.

IPC: B66C23/94
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the bad influence caused by the delay of the response of an electromagnetic proportional pressure reducing valve. SOLUTION: Slow return valves 14A and 14B are arranged in the pipe passage between pilot valves 4A and 4B driven by an operation lever 5 and a direction control valve 1 for swinging, and two pipelines 6A and 6B connecting a hydraulic motor 2 and the direction control valve 1 for swinging are also connected through a electromagnetic proportional valve 9 to control the valve opening degree of the electromagnetic proportional valve 9 by the control signal from a controller 12.  Since this constitution causes a delay in the switching operation of the direction control valve 1 to a neutral position, the delay in the response of the electromagnetic proportional valve 9 to the switching speed of the direction control valve 1 is canceled out, as a result, a desirable neutral free state can be obtained without suddenly increasing the pressure of the outlet side pipe passage of a hydraulic motor 2.
