Patent number: 11691324Abstract: An injection molding device includes an injection machine, a molding die, and a high frequency oscillation device. The injection machine injects a resin material containing a dielectric heat generating material while keeping fluidity by temperature control. The molding die includes a cavity being a channel of flow of the resin material, and a pair of electrodes, each of which faces the cavity, the pair of electrodes being disposed to sandwich the resin material therebetween in a direction crossing a direction of the flow. The high frequency oscillation device applies a high frequency alternate-current voltage to the pair of electrodes.Type: GrantFiled: March 30, 2018Date of Patent: July 4, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Hidekazu Kato, Michihisa Iwamoto, Yasuhiro Tominaga, Takahiro Tanaka, Teruyuki Hamada

Publication number: 20200139483Abstract: A resistance welding machine includes a first electrode and a second electrode which are configured so that the first and second electrodes can hold a workpiece therebetween and apply a current to the workpiece. The first electrode includes a first inner electrode and a first outer electrode disposed outside the first inner electrode at a predetermined interval. The second electrode includes a second inner electrode and a second outer electrode disposed outside the second inner electrode at a predetermined interval. The resistance welding machine further includes a control unit that can control a pressing state of the workpiece with the first and second electrodes according to predetermined welding conditions and selects a pair of electrodes that apply a current to the workpiece from the first inner electrode, the first outer electrode, the second inner electrode, and the second outer electrode.Type: ApplicationFiled: October 22, 2019Publication date: May 7, 2020Applicant: MAZDA MOTOR CORPORATIONInventors: Kojiro YAMAGUCHI, Katsunori TAKAHASHI, Motonori MORIWAKI, Masanori NAKAI, Koichiro ICHIHARA, Yasuhiro TOMINAGA, Naoki UJIHIRA

Publication number: 20200101698Abstract: A joining apparatus is an apparatus for performing joining of a joining target object including multiple members stacked on each other and a thermosetting adhesive arranged on joining target portions of the multiple members. The joining apparatus includes a first electrode; a second electrode; a pressurization mechanism configured to cause the first and second electrodes to pressure-contact the surface of the joining target object in the vicinity of the joining target portions; a power source configured to distribute power to between the first electrode and the second electrode; and a control unit configured to distribute the power to between both electrodes by the power source in a state in which the first electrode and the second electrode pressure-contact the surface by the pressurization mechanism, thereby performing joining of the joining target object by curing of the thermosetting adhesive by resistance heating generated at the joining target object.Type: ApplicationFiled: September 26, 2019Publication date: April 2, 2020Applicant: MAZDA MOTOR CORPORATIONInventors: Kojiro YAMAGUCHI, Katsunori TAKAHASHI, Motonori MORIWAKI, Masanori NAKAI, Koichiro ICHIHARA, Yasuhiro TOMINAGA, Naoki UJIHIRA

Patent number: 4521016Abstract: An apparatus for practicing tennis or other ball games including a pair of upstanding posts, an elastic cord extending between the posts and a ball connected to the elastic cord. A vertical net is arranged forwardly of the post and in the path of movement of the ball. When the ball is struck, the elastic cord stretches until the ball contacts the net which causes dissipation of at least some of the stored energy in the ball, thus reducing the rate of return of the ball towards the posts.Type: GrantFiled: February 23, 1982Date of Patent: June 4, 1985Inventor: Yasuhiro Tominaga
