  • Publication number: 20140285052
    Abstract: A coil includes: a coil main body in which one coil end in an axial direction is bent to an inner peripheral side of a stator core including a tooth having an protrusion preventing portion configured to prevent the coil from protruding to the inner peripheral side of the stator core; and a relief portion provided for a portion of the coil main body that is bent to the inner peripheral side of the stator core. The relief portion is configured to release the protrusion preventing portion of the tooth when the coil main body is inserted into a slot of the stator core in the axial direction from one coil end in the axial direction that is bent to the inner peripheral side of the stator core.

  • Patent number: 5587260
    Abstract: There is provided a method of forming a micro-patterned functional film with a high precision on a substrate comprising:(a) a step of forming a positive or negative-type photoresist film on the entire surface of a substrate having a conductive layer thereon;(b) an exposure step of irradiating light to the surface of the already formed positive or negative-type photoresist film through overlapped photo-masks having patterns that makes the film cover the substrate except for the predetermined part for forming a functional film in the next developing step;(c) a developing step of removing the photoresist film of the predetermined part for forming a functional film;(d) a step of forming a functional film on the substrate in the part where said photoresist film is removed, by electrodeposition with said conductive layer as one electrode; and(e) a step of removing the positive or negative-type photoresist film remaining after the step (c).

  • Patent number: 4812387
    Abstract: The present invention is for a method of forming a coating film used for filling the space between the color stripes for a color filter which is used for colorization of a liquid crystal display. In particular, the light-shielding electrodeposition coating is first formed in a transparent electric conductive circuit pattern so as to suppress the reaction of a photo-setting material against light which is to be applied to the electrodeposition coating.

  • Patent number: 4208261
    Abstract: An improvement in a method for coating an electrically conductive article by electrodeposition, wherein the article, as the cathode, is immersed in an aqueous bath containing a basic resin, at least partially neutralized with an acid compound, and a particulate synthetic resin, is provided. The improvement is the conducting of the electrodeposition continuously while adding a replenishing supply liquid to the aqueous bath to maintain a constant bath composition. The composition of the replenishing supply liquid is such that (a) the proportion of water is smaller than in the initial aqueous bath, (b) the proportion of the basic resin to the acid compound is larger than employed in the initial partial neutralization, and (c) the particulate synthetic resin is also present.

  • Patent number: 4201644
    Abstract: The present invention relates to a method for replenishing an electrodeposition coating bath by subjecting to an ultrafiltration, an electro-deposition bath liquid which has been decomposed with time under a pressure of 0.2-3.0 kg/cm.sup.2 changing the direction of the bath liquid during the ultrafiltration step so as to cause the liquid to flow in opposite directions in the ultrafiltering apparatus; recycling the concentrate obtained from the ultrafiltration to the electrodeposition coating bath for the purpose of adjusting the liquid characteristics of the bath and using the thus-obtained filtrate, obtained from the ultrafiltration, the diluent for preparing a replenishing supply liquid.
