Title: Arc welding method
Inventor: ENDOU KIJIYUU
IPC: B23K9/12
Filed: 1984-04-20
Abstract: PURPOSE:To generate substantially no spatters in a wide welding current region from low to large current by superposing respectively optimum pulse currents in the stage of a short circuit and in the stage of an arc on the base current substantially smaller than said currents by detection signals for the short circuit and arc so that the short circuit is forcibly executed. CONSTITUTION:The voltage transformed 3 to a prescribed voltage range and rectified 4 to DC is applied to an electrode 7c to generate an arc 7d between the electrode 7c and a base metal 7a when said voltage is outputted. The electrode 7c is fed at a constant speed by feed rollers 7a in this stage. The voltage is set at a prescribed voltage by a reference signal generating circuit 11 when the arc is transferred to the short circuit. The set voltage and the detected 9 voltage are compared 10 and the short-circuit is discriminated. The pulse current for the short circuit is passed in the stage of about <=0.5ms instantaneous short circuit at which the molten metal at the tip of the electrode contacts merely the molten pool and does not cause transfer to prevent generation of the spatters. The pulse current for the short circuit flows at the same instant after thorough short-circuiting and therefore the spatter to be generated when the arc is transferred to the short circuit is prevented.

SOLUTION: This agent comprises a polymer having such a functional conjugated enone structure of formula I, II, III or IV (wherein P<1> to P<4> , and Q<1> to Q<4> are each an organic group containing an aromatic ring; and R<1> to R<8> are each H or alkyl) that it is optically excited by radiation and then releases energy to return to a stable state in the principal chain or on the side chain. The polymer used preferably comprises a polyimide because of excellent heat resistance, although there is no limitation. A desired polyimide is obtained by using a tetracarboxylic acid dianhydride component having a structure of the formula or a diamine component.  The liquid crystal alignment agent is produced by dissolving the polymer in an organic solvent, and adding thereto if necessary, e.g. a thermosetting crosslinking agent for strengthening the coating film, and a silane compound for improving the adherence.

Title: Drop sensor for ink jet printer
Inventor: TAMAI MASAYOSHI
IPC: B41J2/125
Filed: 1983-05-06
Abstract: PURPOSE:To perform detection of a two-dimensional position of an ink drop at higher detection response velocity and to prevent contamination of the detecting member, by, in the two-dimensional position sensor of ink drop, focusing an image of an ink drop on an optical detecting member by means of lenses is performed. CONSTITUTION:When an ink drop 1 passes through a space between a light source 3 and lens-alley 2, its image is focused in any of diode-alleys 4 to reduce light-receiving quantity of the photo-diode and by comparison of output group of the alley, the position through which the ink drop 1 passes can be decided. Further, when the ink drop 1 drifts in the vertical directions, as the focal length l2 of the lens-alley 2 becomes deviated from the position of an object to be photographed, if a contrast magnitude of the center of image with respect to the neighboring diodes is measured by the diode-alley within the accuracy of 1%, the drift distance can be obtained by the contrast magnitude. Thus, detection at high response velocity becomes available and contamination with ink can be limited to a minimum by enlarging the distance between light emitting and receiving points.
