Inventor: INUI MASAHIRO
IPC: B23K9/16
Filed: 1991-09-25
Abstract: PURPOSE:To omit a backing strip in a U-shaped groove. CONSTITUTION:In a butt-welding for steel pipe, a root surface of the groove is abutted and by using gas having four elements composed of 40-70% Ar, 3-10% CO2, 0.1-1% O2 and the balance He as the shield gas in the inner surface welding, a consumable electrode type arc welding is executed. The four-element gas having the above component ratio has higher potential gradient, generates more intense plasma gas stream and makes the energy density larger and can form the wider bead having deep depth of fusion in the comparison with single gas of Ar and CO2 or Ar-CO2 mixed gas usually used as a shield gas. Therefore, even if the core of a torch is shifted a little to the groove faced surfaces from the inner surface of the pipe, the welding metal from the inner surface of the pipe and the welding metal from the outer surface are surely joined and the reliability of the welded part can be improved. Further, the depth of the fusion can be obtd. at about 10mm, and the depth of the is made shallow by the above depth and the welding time from the outside can be shortened.

Title: Image forming device
Inventor: ITO NORIYUKI
IPC: G03G15/14
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To dispense with a sensor for detecting the presence of an image carrier to reduce the cost by detecting the transfer current of a transfer charged roller by a detecting circuit, and reading its output voltage to judge the presence of the image carrier. SOLUTION: When a cartridge is installed into a device body, or a photoreceptor drum (image carrier) 114 is in contact with a transfer charged roller 115, the input voltage to an operation amplifier 304 corresponds to a voltage obtained by subtracting a voltage drop caused in a detecting resistor 303 by the current value (transfer current) carried to the photosensitive drum 114 through the transfer charged roller 115 from a current voltage VCC supplied by a power source device. When no cartridge is installed, the input voltage to the operation amplifier 304 corresponds to the DC voltage VCC from the power source device. Thus, a CPU 305 can precisely judge the presence of the photosensitive drum 114 to the device body by reading the output voltage of the operation amplifier 304.

IPC: H01R13/64
Filed: 1991-08-30
Abstract: PURPOSE:To provide a connector for a coaxial cable which can detect imperfect fitting of a plug in a jack. CONSTITUTION:The length L of a probe 25 is set such that the tip of the probe 23 comes into contact with the flange 8b of a plug 7 when the plug 7 is normally fitted in a jack 1. A flange 8b is made to contact with the probe 23 by fitting the plug 7 in the jack 1 to push the plug 7 until it reaches a normal coupling position, and the jack 1 is electrically connected to the probe 23 through the plug 7. If a wire 25 and a wire 26 are conducting, therefore, it is possible to detect that the jack 1 and the plug 7 are perfectly coupled. Unless the plug 7 is pushed in until it reaches the normal coupling position, the flange 8b of the plug 7 does not come into contact with the probe 23 and the Jack 1 is not electrically connected to the probe 23. Resultantly, if the wire 25 and the wire 26 are not conducting, it is possible to detect that the coupling of jack 1 with the plug 7 is imperfect.
