Title: Method for preventing drain-generation in dust catcher of vacuum degassing vessel and drain-generation preventing dust catcher
Inventor: TANIISHI HIKOFUMI
IPC: F27D17/00
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To prevent the slurry state dust from fixing in the inside of a dust catcher caused by generating the drain in the preheated exhaust gas and changing the dust in the dust catcher into the slurry state by making inert gas flow into the dust catcher in the case of preheating a vacuum degassing vessel. SOLUTION: The preheating work of a vacuum degassing vessel 1 is executed by closing a cutoff valve 8 disposed at the downstream side of a dust catcher 3. Thereafter, the inert gas is filled in the dust catcher 3 from the inert gas supplying piping 12 and the inert gas filled therein is exhausted to the vacuum degassing vessel 1 side. As a result, the inner part of the dust catcher 3 is replaced into the inert gas atmosphere, and since the exhaust gas at the preheating time, is not made to flow into the dust catcher 3 and the combustion reaction of fuel gas is not developed, H2O is not generated. Therefore, since a gas cooler 4 does not come into contact with the H2O, the drain-generation in the dust catcher 3 can be prevented.

Title: Laser device
Inventor: TAKAGI SHIGERU
IPC: H01S3/097
Filed: 1979-03-27
Abstract: PURPOSE:To readily start glow discharge of a laser device by a gas laser excitation by so connecting a rectifier thereto as to apply the sum of a discharge retaining voltage between an interval and a voltage for starting the discharge to the interval before the discharge is started at the interval. CONSTITUTION:A DC power supply 9 is set at 2-3kV, the voltage of a DC power supply 4 is raised. When the sum of both the voltages become approx. 6.2kV, a discharge is started to flow a current among anode 1-cathode 2-resistor 10-resistor 6. When the voltage of the power supply 4 is further raised, a current is flowed in a circuit of anode 1-cathode 2-resistor 10-resistor 5-diode 8, but no current is flowed from the trigger power supply 9. Since the cathode is commonly used for the trigger electrode, even if the discharge current flowing through the cathode is increased, the glow discharge is not transformed to the arc discharge and the discharge can be readily started.

Filed: 1991-03-01
Abstract: PURPOSE:To compatibly obtain both of a high output characteristic and flawing property by specifying the average surface roughness on the magnetic layer side of metallic foil and the ratio between the average surface roughness of the surface not coated with the magnetic layer and the max. height to respectively specific ranges. CONSTITUTION:The magnetic recording medium is constituted by providing the magnetic layer on one surface of the metallic foil. The average surface roughness Ra on the magnetic layer side of this metallic foil is required to be 2 to 100nm and the ratio Rt/Ra between Ra of the surface not coated with the magnetic layer and the max. height Rt to be <=15. The Ra larger than the above-mentioned range leads to the defective output characteristic and is, therefore, undesirable. The Ra smaller than this range leads to the generation of flaws by contact with rolls, etc., in the stages before the application of the magnetic layer and is, therefore, undesirable. The Rt/Ra larger than the above- mentioned values causes the flawing of guide pins in the case of tape traveling and is, therefore, undesirable.

Title: Image forming device
Inventor: SUGA AKIRA
IPC: G03G15/00
Filed: 1992-02-24
Abstract: PURPOSE:To obtain a small sized low cost image forming device with a read sensor without staining the surface of a copy by a method wherein the read surface of the read sensor is so arranged as to face the surface opposed to the printing surface by an image forming part of paper. CONSTITUTION:When image information of a copy is read, the copy of a cassette paper feeder 1 passes through a paper feed path 3, and is read with a read sensor 16 while it is being transferred through a transfer path 4 by taking timing with a pair of timing rollers 17. Then, the copy which has passed through the sensor 16 and finished to be read, passes through a photosensitive material 6 and a fixing device 6 in the same way as of the recording paper in printing and is discharged to a delivery part 13. Herein, the read surface of the paper when the copy is read becomes the rear surface opposite to the printing surface of the paper when an image is formed on the recording paper. Therefore, though the copy is intended to be contained as the paper in the paper feed part 1 to perform read operation, printing operation happens to be erroneously performed. Though toner sticks to the paper with the photosensitive material 6, since the toner adhering surface is the rear surface not the copy surface, the copy surface is avoided from being stained.
