Abstract: IN A METHOD OF MANUFACTURING A GLASS GOB, A DOWN-FLOWING MOLTEN GLASS (G) IS RECEIVED ON A MOLDING DIE (102). THE MOLDING DIE (102) IS MOVED DOWN AT A SPEED HIGHER THAN A DOWN-FLOWING SPEED OF THE MOLTEN GLASS (G) SO AS TO CUT THE MOLTEN GLASS. THE MOLTEN GLASS IS REMAINED WITH A PREDETERMINED WEIGHT ON THE MOLDING DIE (102). THE MOLTEN GLASS (G) IS SPRAYED WITH GAS IN ORDER TO FORM THE GLASS GOB UNDER SUCH A CONDITION THAT THE MOLTEN GLASS IS FLOATED OR SLIGHTLY FLOATED. THE RECEIVING STEP IS CARRIED OUT BY SPRAYING THE MOLTEN GLASS (G) WITH GAS HAVING A FLOW RATE LOWER THAN THE GAS USED IN THE SPRAYING STEP, OR THE RECEIVING STEP IS CARRIED OUT WITHOUT PERFORMING THE GAS SPRAYING.(FIG 6A,6B,6C,6D,6E)

Abstract: PROBLEM TO BE SOLVED: To manufacture glass gob having high quality and high precision in weight with high productivity. SOLUTION: A driving signal 1 for starting the drive of a conveying means 108 is sent and hereby a molding die is conveyed to a casting position. When a signal showing that the drive of the conveying means is completed is received, a driving signal 2 for starting the drive of a molding die raising/lowering means is sent and hereby the molding die is raised to receive the tip of molten glass in the molding die and then the molding die is lowered to receive molten glass of fixed weight in the molding die. When a predetermined time passes after the driving signal 1 is sent, the driving signal 1 is sent again and hereby the glass gob-received molding die is conveyed and an empty molding die is conveyed to the casting position.

Abstract: PROBLEM TO BE SOLVED: To prevent the floating of cut pieces at the time of pressurizing and cutting in a method for cutting a planar glass preform previously scribed with a plurality of grooves on one main surface. SOLUTION: When a presser 191 cuts the material 20 to be cut, the cut pieces of the material 20 to be cut tend to float up. However, buffer members 193a, 193b are mounted at the circumference of the presser 191 and, therefore, these buffer members 193a, 193b properly press down the cut pieces to prevent the floating up thereof. The colliding of the adjacent cut pieces against each other and the chipping of their corner parts may, therefore, be prevented. The press blank of a uniform weight may, thereby, be formed.

Abstract: PROBLEM TO BE SOLVED: To obtain a high quality glass ingot by reducing the contact of the glass ingot with the molding surface at the horizontal transferring of the mold. SOLUTION: This method for forming a glass ingot uses a mold 102 having a concave molding surface 102a which receives a described weight of molten glass at the casting position and forms this into a glass ingot, where the mold 102 has a plurality of gas jetting nozzles 132 at positions along the periphery g and inside of the glass ingot put on the molding surface at the molding surface 102a, which eject a gas to float or nearly float the glass ingot. The gas ejected from nozzles disposed at positions along the periphery of the glass ingot not only functions to float or nearly float the glass ingot but also acts as a resistant force to the movement in the horizontal direction generated in the glass ingot caused by horizontal transferring of the mold.

Abstract: PROBLEM TO BE SOLVED: To produce glass gobs of high quality and high weight accuracy with high productivity. SOLUTION: A drive signal 1 to start driving of a transfer means 108 is delivered, by which a formed die is moved to a casting position. A signal indicating that the driving is completed is received and, when this signal is received, the drive signal 1 to start the driving of a lifting means for the formed die is delivered, by which the forming die is risen to receive the front end of molten glass and thereafter the forming die is lowered to receive the molten glass of a specified weight. The drive signal 1 is delivered at the time when a predetermined time elapses after the receipt of the signal indicating the delivery of the driving signal or the completion of the drive signal, by which the forming die receiving the glass gob is transferred and the empty formed die is transferred to the casting position.

Abstract: PROBLEM TO BE SOLVED: To obtain a gas treatment apparatus and gas treatment filter which are capable of efficiently developing a photocatalytic reaction and are small in size and high in treatment capacity. SOLUTION: The gas treatment unit 1 has a multiplicity of photocatalytic fibers 3 held between metallic filters 2 as air permeable members in a bundled state. Photocatalytic fiber 3 is formed by depositing a photocatelyst having the refractive index higher than the refractive index of a fiber-like guide body having projections on the surface of the light guide body. The gas to be treated flows through the gaps of the many photocatalyst fibers 3 bundled between the metallic filters 2. On the other hand, the UV rays from a UV light 6 are cast to the end faces of the photocatalystic fibers 3 and leaks out to the photocatalyst on the surface of the light guide bodies while propagating in the photocatalytic fibers 3. At this time, the malodorous components, etc., included in the gas are brought into contact with the photocatalyst excited by the UV rays and are decomposed by the photocatalytic reaction.

Abstract: PROBLEM TO BE SOLVED: To make it possible to exactly form a member to be cut in a process for producing a grooved planar glass preform having a groove which may be cut by impression of a local stress. SOLUTION: The optimum blade edge angle θ of a wheel cutter 161 is determined by θ=a-bβ1+cβ2. The coeffts. a, b, c respectively attain values 100 to 200, 1 to 2, 0.5 to 0.6, more preferably 141.01 to 142, 99, 1, 3 to 1.48, 0.51 to 0.55. In addition, β1 is a parameter indicating the thickness of the planar glass preform and β2 is a parameter indicating the material quality of the planar glass preform. As a result, an adequate crack may be formed at the time of scribing the planar glass preform. The good-quality press blank may be formed after cutting.

Abstract: PROBLEM TO BE SOLVED: To provide a method of producing a glass gob which makes it possible to produce a glass gob low in weight dispersion and having high quality. SOLUTION: The method of producing the glass gob comprises a first process wherein a molten glass flow is received in a molding die; a second process wherein the molten glass flow is divided by lowering the molding die at a speed faster than down flow velocity of the molten glass, and the molten glass with a predetermined weight is left in the molding die; a third process wherein the glass gob is formed in a state in which the molten glass left in the molding die is floated or almost floated by being sprayed with gas. The first process is carried out by spraying the gas having a rate of flow lower than that in the third process on the molten glass flow or alternately without spraying it.
