Title: Charging method for lead-acid battery
Inventor: AOYANAGI TOSHISUE
IPC: H01M10/44
Filed: 1986-08-13
Abstract: PURPOSE:To retard the consumption of water caused by electrolysis to increase charge efficiency by charging a battery at voltage obtained by adding lower voltage than hydrogen overvoltage to equilibrium potential of the battery, and supplying a gas in an electrolyte in the final stage of the charge from the lower part inside the battery to generate bubbles in the electrolyte. CONSTITUTION:Charging voltage obtained by adding lower voltage than hydrogen overvoltage of electrode to equilibrium potential of a battery is applied across terminals 8 from a charger 2 to charge a lead-acid battery. In the final stage of charge, a compressor 3 is drived and the air is supplied into an electrolyte 5 from the tip of a pipe 9 arranged in the bottom inside a battery 1 to generate bubbles in the electrolyte 5. By supplying the gas to the electrolyte 5, the battery 1 is charged at low voltage, and the electrolysis of the electrolyte 5 is retarded to decrease the consumption of water. By the rise of bubbles generated by supplying the gas in the electrolyte, the electrolyte near a plate group 6 is mixed with that of the other part, and the whole electrolyte is made uniform, and charging efficiency is increased.

Title: Semiconductor led
Inventor: UJI TOSHIO
IPC: H01L33/30
Filed: 1981-11-25
Abstract: PURPOSE:To contrive the improvement of the linearity of the current-photo- output characteristic withot largely deteriorating the fiber coupling power, by suitably choosing the band gap energy of each semiconductor layer in an LED constituted of III-V group compound semiconductors. CONSTITUTION:On an N type InP substrate 21, an N type InP layer 22 with band gap energy Eg=Eg1, a P type InGaAsP layer 23 (Eg=Eg2<Eg1), a P type InGaAsP layer 24 (Eg=Eg3>Eg2), a P type InGaAsP layer 25 (Eg=Eg4<Eg2) and a P type InP layer 26 (Eg=Eg5>Eg4) are successively formed. When the current is passed through this LED in a forward direction, the electron-hole recombination occurs. When this current is further increased, the electron leak current exceeding the hetero barrier between the layer 24 increases. The remnant recombined in the layer 24 of electrons exceeding this barrier reaches the  layer 25, recombines with holes there and emits the light of energy Eg4. Since the current injected into this layer 25 is the electron leak current, the linearity  of the current-photo-output characteristic is largely improved.
