Title: Preparation of molten glass
Inventor: AKASHI HISATOMO
IPC: C03C1/00
Filed: 1980-01-19
Abstract: PURPOSE: To extinguish foams occurring on the surface layer of molten glass and to increase solubility per hour without reducing the quality of a product, by adding solid sulfur to the surface of molten glass in a tank furnace at a place after a feed opening for a raw material.  
     CONSTITUTION: The foam layer 10 is always formed on the surface layer of molten glass near the glass raw material heap 9 fed from the feed opening 4 equipped at one end of the dissolving bath 2 of the tank furnace 1. Since the foam layer has good heat insulating properties, the increase or its area with the expansion of feed of raw material reduces the heat transfer from the atomosphere in the tank furnace to the molten glass 6, dissolution and purification actions decrease, and the formation region of the foam layer 10 widens further, bringing about the cause of bad product. The addition of solid sulfur near the rear part of the dissolving both 2 or the front part of the adjusting bath 3 extinguishes foams by its jumping and pufifies molten glass. Though an amount of the solid sulfur to be added differs depending upon the structure of a furnace, an amount of the raw material to be added per hour, etc. and is not decided readily, about 0.01W1kg solid sulfur based on 1 ton molten glass is preferable.

Filed: 1980-01-19
Abstract: PURPOSE:To enable not only conventional dielectric paper but plain paper to be used as a recording sheet by forming electrostatic latent images directly on the  recording sheet by making use of the characteristic of a photoconductor that when it receives light its electrostatic capacity increases. CONSTITUTION:A recording head 11 consists of a photoconductor 15 which is joined with a transparent electrode 13 in the upper part and a multistylus electrode array 14 in the lower part electrically respectively, and a supporting body 16 which holds and insulates the respective multistylus electrodes of the multistylus electrode array 14 independently respectively, and holds the entire part. Now, when light enters the transparent electrode 13 from above, the photoconductor 15 conducts and decreases its resistance; at the same time, its electrostatic capacity CP increases. Here, if CS is defined as the electrostatic capacity of a dielectric recording sheet 20, VS as its potential and QS as its charge, the relation QS=VS/[(1/CP)+(1/CS)] holds, and the charge patterns corresponding to the brightness and darkness of the light are formed on the recording sheet.

Title: Liquid-sealed bush
Inventor: MIYAMOTO YASUO
IPC: F16F15/02
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To provide a liquid-sealed bush capable of reducing a high frequency road noise to be transmitted from a road surface via a suspension arm. SOLUTION: Frequency where a dynamic spring constant K* of this liquid- sealed bush becomes minimized, or another frequency, where a loss factor tan δbecomes maximized, should be set in and around the rigid resonance frequency f0 of a suspension arm (for example, 600 Hz). Consequently, transfer force N (transfer force N = resonant multiplying factor γ × dynamic spring constant K*) of vibration in and around the said rigid resonance frequency to be transmitted from a road surface via the suspension arm is reduced, whereby a road noise is reducible.
