Title: Shaping of plate glass
Inventor: KITAI ZENTARO
IPC: G02F1/1333
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for shaping a plate glass by slit-down shaping process so as to enable waviness development thereon to be suppressed. SOLUTION: A heating element 15 is mounted on the lower part of a lip section 11'; when a glass ribbon 12 run out through a slit 11 is heated by the heating element 15, the surface temperature of the ribbon 12 can be brought to a level nearly equal to or higher than its inner temperature without quenching the surface of the ribbon 12, thus enabling the temperature-falling rates both on the surface of and inside the glass ribbon 12 to be nearly equal to each other.

Title: Agent and method for damping vibration at road joint
Inventor: AMANO TOKIMOTO
IPC: E01C11/02
Filed: 1995-12-29
Abstract: PROBLEM TO BE SOLVED: To damp vibration at a road joint and to thereby prolong the maintenance cycle of the joint by pouring an aqueous solution containing a polyvalent metal salt of (meth)acrylic acid and a polymerization catalyst into the joint and curing the poured solution. SOLUTION: The aqueous solution contains 8wt.% at least one polyvalent metal salt (e.g. Mg salt, Sr salt or Al salt) of (meth)acrylic acid. The polymerization catalyst is desirably a water-soluble redox catalyst being a combination of an oxidizing agent with a reducing agent or an azoic catalyst. The combination of an oxidizing agent with a reducing agent and its amount of use are determined in consideration of the kind, concentration and pH of the polyvalent metal salt of (meth)acrylic acid used, and the formation time, strength, etc., of the hydrogel to be formed. It is usually used in an amount of 0.1-10wt.%. The oxidizing agent is exemplified by ammonium persulfate, and the reducing agent is exemplified by sodium thiosulfate.  Although the amount of the vibration damping agent poured is at least the total voids of the joint or its area, it is desirably applied in a thickness of 5mm or above.

Abstract: PURPOSE:To heighten electrolyte holding power, and prevent a layer forming phenomenon by filling granular SiO2 having constant shape pores between a positive electrode plate and a negative electrode plate and around a plate group, and holding electrolyte reliably by this in a sealed type lead-acid battery formed by absorbing oxygen gas generated from the positive electrode plate in the negative electrode plate. CONSTITUTION:After a positive electrode plate and a negative electrode plate are assembled by using a grid body of Pb-Ca-Sn alloy and this is inserted in a battery jar, spherical SiO2 having a particle diameter of 150-500mum is filled between the positive electrode and the negative electrode and around a plate group. Here, pores having an average diameter of 450Angstrom  are provided in the spherical SiO2, and these pare capacity is set in 1.2cc/g. In this way, fluidity of the SiO2 is heightened, and filling in a battery is carried out in a short time. Thereby, porosity of not less than 80% is created in the SiO2 in a filling condition, so that electrolyte necessary for charge and discharge can be held sufficiently.
