20150194651 | SQUARE SECONDARY BATTERY - A square secondary battery suppresses welding failure from occurring by temporarily retaining and securing a sealing cover and enabling detection by a leakage test even when welding failure occurs. The square secondary battery has a case surface portion with an injection opening for injecting an electrolyte, a sealing cover disposed at a position opposite to the case surface portion and sealing the injection opening and having an outer edge welded to the case surface portion to seal the injection opening, and a pressure sensitive adhesive member interposed between the sealing cover and the case surface portion for securing the sealing cover to the case surface portion. A gas passage is provided between the case surface portion and the sealing cover for communicating a gap formed at a position outer to the pressure sensitive adhesive member with respect to a battery case and the injection opening in a ventilation manner. | 07-09-2015 |

20140096517 | PRIMARY PISTON COMPONENT FOR A MASTER CYLINDER OF A HYDRAULIC BRAKE SYSTEM AND METHOD OF OPERATING A HYDRAULIC BRAKE SYSTEM - A primary piston component for a master cylinder of a hydraulic brake system includes a primary piston housing and an additional piston component, which is configured to be at least partially movable into a cavity of the primary piston housing. An inner piston body extends through the cavity along a central line of the primary piston component. A braking force applied on a brake actuating element is transferable at least partially on the inner piston body, and further on the primary piston housing. The additional piston component is at least partially movable into the cavity between the inner piston body and the primary piston housing, and a brake booster force is transferable at least partially on the additional piston component, and via the inner piston body on the primary piston housing. A method of operating a hydraulic brake system is also described. | 04-10-2014 |

20140054062 | INSULATING VARNISH AND INSULATED ELECTRICAL WIRE USING SAME - An insulating varnish forms an insulating coating film having a shape that corresponds to the shape of an opening of a die, having a uniform thickness. The insulating varnish is applied onto a surface of a conductor, subsequently passes through a die to remove the excess applied insulating varnish, and is then dried or baked to form an insulating coating film on the surface of the conductor. The insulating varnish has a viscosity of 10 Pa·s or more measured by a B-type viscometer at 30° C. The insulating varnish preferably contains no filler, and is preferably a polyimide precursor solution. Since the insulating varnish has a high viscosity, baking and solidification can be performed while maintaining a shape formed when the insulating varnish passes through a die. | 02-27-2014 |
