Title: Method and device for cleaning with solvent
Inventor: ANDOU KEIJI
IPC: B08B3/08
Filed: 1982-03-03
Abstract: PURPOSE:To reduce energy for heating chlorine base org. solvents and the consumption of the solvents with simple constitution, by changing the capacity of heaters for heating a vapor degreasing and cleaning tank using said solvents between the idling stage and the stage under substantial working. CONSTITUTION:A chlorine base org. solvent 11 such as 1.1.1-trichloroethane is kept heated at all times with a heater 6 during idling in the stage of heating the solvent 11 with electric heaters 5, 6, and subjecting materials 10 to be cleaned such as metallic parts conveyed into the solvent with an elevator 7 for upward and downward movement within th vapor layer 9 formed by said heating. In the stage of carrying the objects 10 into the cleaning tank with conveying rolls 3, the objects contact with a limit switch 1 which turns the power source of the heater 5 on, thereby increasing the rate of generating the vapor of the solvent 11. In the stage of removing the objects 10 and discharging the same with conveying rolls 4, the objects contact with a limit switch 2 which turns the power source of the heater 5 off. The above-mentioned purpose is achieved even if the heaters 5 are turned on and off at specified time intervals with a programed controller.

Title: Flame burner for processing glass, glass lathe and glass processing
Inventor: SHIMIZU YOSHIMASA
IPC: C03B23/043
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To improve heat resistance and oxidizing resistance and prevent deterioration of mechanical strength or the like under high temperature, by forming a nozzle of a flame burner with a specific material. SOLUTION: A glass processing flame burner 20 has a nozzle 23 of conical trapezoid at the head of a cylindrical body. When the nozzle 23 is seen from the direction of its tip, auxiliary combustion gas is discharged from dozens of pipe-like slender nozzles 25 and combustible gas is discharged from a gap 26 between an outer case 24 of the nozzle 23 and the nozzles 25. Ni or SUS310S having an excellent heat resistance and oxidizing resistance is used for a material of the nozzle from which oxygen is discharged. The nozzle 25 made of Ni or 310S consists of about 60 pipes with their base being brazed to a brass stand. Even if the tip of the nozzle is exposed in a high temperature oxyhydrogen flame for a long time, a metal oxide is formed, followed by parting of a thin film thereof, thereby preventing attachment and mixing to an object to be processed.  In this way, operation can be stabilized through the processing period and the quality can be improved.

Title: Fault generation condition recorder
Inventor: TOMITA YUJI
IPC: G01M99/00
Filed: 1989-02-14
Abstract: PURPOSE:To prevent the quantity of information, which are stored when a fault is generated, from exceeding the storage capacity of a storage device by detecting the generation of the fault, encoding this fault, storing the fault and storing the new information instead of old stored information when the quantity of the stored information exceeds the storage capacity. CONSTITUTION:When the information of the fault generation are outputted from a CPU 51 by the operation of anyone of sensors S1-S14, a CPU 54 inputs a time from a clock 55 at such a time. A code corresponding to the kind of the generated fault is taken out from information stored in a ROM 52 and the time of the generation and the code of the fault are stored to an E<2>PRPM 56 or to an external memory 57. When the quantity of the stored information concerning the fault exceeds the capacity of the E<2>PRPM 56 or of the external memory 57, instead of these old stored information, the newest information are updated and stored. Thus, even when the information exceeding the storage capacity of the storing means are inputted, the input is not interrupted and the newest information can be stored.

Abstract: PURPOSE: To prevent a discharge accident and abnormal heating while facilitating cleaning by a mechanism wherein the mutual surfaces of contact portions among a grill and a placing base for a body to be heated in metal are faced each other through a thin insulation layer.  
     CONSTITUTION: A grill 9, the noses of legs thereof have discoid spacers 10 in metal, is provided on a round placing base 6 in metal, surface thereof is enamel coated. A diameter l of the spacer 10 in metal is selected in dimensions which l is 0.5/amm or more when the thickness of an enamel film coated on the surface of the round placing base 6 in metal is a mm and is 1/2 or less of the wave length of high frequency used. Consequently, high frequency does not enter between the spacer 10 and the placing base 6, and an electric field existing between both is uniformly dispersed, thus generating no partial heating and discharge phenomen. Since the mounting portions of the grill 9 and the spacer 10 are formed in simple shapes, cleaning is also facilitated.
