Patent number: 6513235Abstract: In a mold for pressing an electric-wire clamping portion of a terminal, a lower side-wall mold part and an upper side-wall mold part are provided for pressing side walls connected to the electric-wire clamping portion. A pressure face substantially continuously connected to a pressure face of an upper conductor mold part is provided on one end side of the upper side-wall mold part. A taper face is provided on the other end side of the upper side-wall mold part so as to be enlarged toward the other end. Accordingly, side walls pressed between the lower side-wall mold part and the upper side-wall mold part are deformed so that the quantity of deformation at one end is near the quantity of compressive deformation of the electric-wire clamping portion and so that the quantity of deformation is reduced gradually toward the other end side. Thus, local stress concentration is not caused in the side walls so that cracks are prevented from occurring in the side walls.Type: GrantFiled: January 31, 2000Date of Patent: February 4, 2003Assignee: Yazaki CorporationInventors: Hideki Ohsumi, Yoshimi Wada

Patent number: 6513239Abstract: An alloy film is fabricated, on the face of a heat exchanger for an integrated circuit, by a process that dispenses various liquids onto the heat exchanger's face. To prevent those liquids from falling off of the heat exchanger's face onto other components which hold the heat exchanger on a frame, the process begins by combining the heat exchanger into an assembly that includes a retainer and a compliant member. The retainer catches any liquids that fall off the heat exchanger's face, and the compliant member forms a seal between the heat exchanger and the retainer which prevents the liquids from leaking onto the other components.Type: GrantFiled: July 24, 2001Date of Patent: February 4, 2003Assignee: Unisys CorporationInventor: Blanquita Ortega Morange

Patent number: 6513242Abstract: A method is disclosed for manufacturing a vehicle body and frame assembly including a pair of side rails, each of which is formed from a single closed channel structural member that extends the entire length of the vehicle body and frame assembly and is deformed into a desired shape by hydroforming. The first step in the process is to provide a length of stock material, preferably a tubular metallic workpiece, having a predetermined length. The tubular workpiece is then typically pre-bent by a conventional tube bending apparatus to have some or all of the bends in the side rails to be formed. The bends initially formed in the workpiece during this pre-bending step usually do not have the exact angles and shapes which result in the final product. Rather, this initial pre-bending operation is performed to facilitate the insertion of the workpiece within a die cavity defined by cooperating die sections of a hydroforming die.Type: GrantFiled: August 15, 1997Date of Patent: February 4, 2003Assignee: Dana CorporationInventors: Paul A.

Patent number: 6513269Abstract: A steam sprayer is used in ironing textile products, including clothes. The steam sprayer is user-friendly and offers highly effective ironing. A vaporizing chamber generates steam by vaporizing water stored in a tank. A water-supplying unit supplies the vaporizing chamber with the water. A steam-ejecting section spouts the steam outside. The steams-ejecting section includes a ironing surface with high frictional resistance characteristics. When touching the ironing surface to clothes or other fabrics for ironing, a pulling force is caused by the frictional resistance, which is a preferable wrinkles-off effect. Thus, the steam sprayer offers a synergistic effect brought by spouting the steam and applying the pulling force to clothes, thereby neatly fixing the form of clothes.Type: GrantFiled: July 26, 2001Date of Patent: February 4, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shinichiro Kobayashi, Toshihide Nakamura, Mamoru Ikeshima, Masao Shimizu

Patent number: 6513279Abstract: A chum dispenser that houses chum for fishing applications. The instant invention is suspended by a rope and is submerged under water to a predetermined depth. It comprises a housing with first and second ends. The housing stores chum and has through holes to allow chum to seep out. The first end has a removable weighted end-cap and the second end has a flap assembly. The rope suspends the instant invention by the flap assembly. Flaps cover the second end of the housing when the instant invention is weighted down by the weighted end-cap. The flap assembly has springs attached to the housing that keep it partially open, exposing the second end of the housing and allowing the chum to exit therefrom when the rope is jerked by the user to overcome the weight of the weighted end-cap.Type: GrantFiled: February 15, 2002Date of Patent: February 4, 2003Inventor: Carlos Hernandez
