Title: Lead-acid battery
Inventor: YABUKI SHUICHI
IPC: H01M2/16
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To lengthen the life by placing a fiber mat and a synthetic resin separator between a positive plate formed by filling a pasty positive active material in a grid substrate made of the specified alloy and a negative plate so that the fiber mat is faced to the positive plate. SOLUTION: A glass fiber mat 3 is closely placed on both sides of a positive plate 1, a polyethylene separator 4 is stacked on the outside of the mat 3, and a negative plate 2 is stacked on the outside of the separator 4 between the positive plate 1 and the negative plate 2 to constitute an electrode plate group A. The positive plate 1 is manufactured by filling a pasty positive active material in a grid substrate cast with an alloy comprising 0.03-0.09wt.% Ca, 1.05-1.50wt.% Sn, and the balance lead. Since the lead grid substrate is easily cast from the specified Pb-Ca-Sn alloy, corrosion resistance is enhanced, a lead-acid battery having a long cycle life at high temperature can be obtained, and the life of the battery such as a car battery used under environment exposed to high temperature is lengthened.

Title: Method of treating thiosulfate-contained liquid
Inventor: FURUTA ISAO
IPC: C01D5/00
Filed: 1977-10-12
Abstract: PURPOSE: To accomplish efficient decomposition to separate thiosulfate contained in the liquid without pollution through conversion of sulfurous acid gas produced in acid decomposition of the thiosulfate-contained liquid into sulfur following a circulating absorption thereof by a thiosulfuric acid contained liquid.  
     CONSTITUTION: A thiosulface contained liquid to be treated involving sulfate and sulfur withdrawn from a thermal decomposition tank 2 is fed to a acid decomposition tank 3 with a pump 6 where thiosulfate is decomposed by sulfuric acid 11 with the liquid controlled to 40 to 95°C and 3 or less in pH. SO 2  yielded as by-product is inducted to a absorption column 1 from a line 10 and absorbed by the thiosulfate- contained liquid through a countercurrent contact therewith. On the other hand, a slurry liquid from an acid decomposition tank 3 is fed to a neutralization tank 4 to be neutralized by alkali and then, proceeded as shown by 7 to solid/liquid separator where it is separated into sulfur 13 in element form and a sulfate-contained liquid 14 to be recovered respectively. With such an arrangement, effluence of SO 2  from the system can be checked reducing the basic unit of sulfuric acid used while accomplishing complete decomposition of thiosulfate

Title: Ternary signal sampling circuit
Inventor: LOSCHER JUERGEN
IPC: H04L25/40
Filed: 1986-05-30
Abstract: In a circuit arrangement for sampling a ternary signal, this ternary signal is divided by amplitude decision circuits into two binary signals and the binary sub-signals are sampled at m-times the rate of the symbol clock. The binary samples of each sub-signal are shifted through a shift register having at least m stages and intermediately stored in a buffer store for one period of the symbol clock. With the aid of a logic circuit it is then determined in which regions of the buffer store accumulations of identical binary values occur. Regions in which the accumulations always re-occur-the number of occurrences is checked by means of counters-are considered to be eyes of the ternary signal. In each clock period of the synbol clock, a sample falling within the eye of the ternary signal is transferred from each buffer store at an output of the circuit with the aid of a gate circuit.

IPC: B41F31/02
Filed: 1985-06-10
Abstract: PURPOSE:To accurately judge the time to supply an ink and obtain stable printed results, by providing a detecting member making contact with a printing cylinder through an ink layer and moved by a fixed amount according to a frictional pulling force generated by rotation of the cylinder, and detecting the displacement of the detecting member. CONSTITUTION:The detecting member 2 formed of a rubber material and substantially L-shaped in cross section makes contact with a substantially central part of the printing cylinder 1, and is supported by a shaft 3. When the detecting member 2 is moved by friction generated by rotation of the cylinder 1, the shaft 3 is oscillated according to the movement. While the ink is sufficiently present, the friction is small, and the member 2 is maintained at the position by a tensile spring 4. When the quantity of the ink is reduced, the frictional pulling force is increased, and the member 2 is moved to a position at which the force is balanced by the force of the spring 4. When the quantity of the ink is reduced below a required quantity, an end part of the shaft 3 presses a lever 6 of a microswitch 5, thereby closing the switch.
