Title: Manufacture of paste type electrode plate for lead storage battery
Inventor: KONISHI HIROSUKE
IPC: H01M4/20
Filed: 1984-03-30
Abstract: PURPOSE:To uniformalize the thickness of a thin lead sulfate film by allowing an electrode plate filled with paste to vertically pass through between a pair of rollers facing horizontally to each other and having sponge treated to contain diluted sulfuric acid therein by dropping the diluted sulfuric acid onto roller surfaces covered with the acid resistant sponge of a specific thickness. CONSTITUTION:An electrode plate 4 is constructed by filling a lead lattice 2 moving on a belt conveyor 1 with paste by a paste filling machine 3. The electrode plate 4 passes between rollers 5, 5' covered with cloth, and vertically between rollers 6, 6' impregnated with diluted sulfuric acid, and moves to a drying furnace 9. The surfaces of the rollers 6, 6' are covered with acid resistant sponges 7, 7' impregnated with diluted sulfuric acid. The sponges 7, 7' are contracted as the electrode plate 4 vertically passes between the rollers 6, 6' whereby all the diluted surfuric acid oozing therefrom is absorbed in the surfaces of electrode plate 4, while eliminating the possibility of its scattering outward. The thickness of each of the sponges 7, 7' is proper to be 5mm.-10mm.. Only pouring sulfuric acid from a sulfuric inlet 8 onto the sponges while preventing the sulfuric acid from dropping down from the lower parts of the sponges 7, 7' enables uniform lead sulfate coating to be formed on the surface of electrode plate 4.

Title: Fluid sealed vibration proofing device
Inventor: YOTANI YORISHIGE
IPC: F16F13/06
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To improve a vibration proofing effect exhibited on the basis of the flowing action of fluid with a simple structure by forming a water repellent coating film on an inside surface of an office passage by surface treating an orifice member to form the orifice passage. SOLUTION: A recessed groove 46 which extends in a length a little less than one round in the circumferential direction on an outer peripheral surface and whose circumferential directional both end parts are opened toward the shaft directional respective one sides, is formed in an orifice metal fitting 34 arranged between a pressure receiving chamber 42 and a balance chamber 44. An orifice passage 50 to communicate the pressure receiving chamber 42 with the balance chamber 44 flows fluid between both chambers on the basis of a pressure difference between the pressure receiving chamber 42 and the balance chamber 44 at vibration input time, and exhibits a vibration control effect by the resonance action of the fluid.  A water repellent coating film is formed on the inner cylinder whole surface of the recessed groove 46, and since flowing resistance of the fluid in the orifice passage 50 is reduced, the vibration proofing effect on the basis of the resonance action of the fluid is remarkably improved.

Filed: 1981-04-28
Abstract: PURPOSE:To compensate tracking shift, by integrating an FM siganl level reproduced with a shaking rotating head through sampling at each specified section for each track and controlling the amount of track shift from the integrated value through detection. CONSTITUTION:A pulse generator 8 generates a sampling pulse synchronized with a rotating head and opens a gate 7. An FM reproducing output is envelope- detected at 5 and inputted to a voltage controlled oscillator VCO6. A counter 9 integrates an output of the VOC6 from the gate 7 and stores it at 11. Counting values at each field are compared at 12, an output signal is stored at 13 as a track shift signal and summed at 15 with a shaking signal from a pulse generator 8 as a shift correction tracking signal via a tracking signal generating circuit 14. The addition output controls a head moving mechanism 17 via a driving amplifier 16, and a rotating head makes reproduction at higher and lower positions than a reference in accordance with the shaking signal. Thus, the track shift can accurately be compensated.
