Patent number: 7445539Abstract: Described is a toy vehicle with a launcher for connecting with and launching the toy vehicle. The toy vehicle includes a vehicle housing having a wheel opening in the housing for placement of a detachably attachable wheel and a vehicle strip opening for placement of a strip. A gear system is attached with the housing. The gear system includes gear teeth for engaging at least a part of the gear system with the strip. A rotating end is connected with the gear system for placement of a detachably attachable wheel. When the wheel is affixed with the rotating end, and when the strip is inserted into the vehicle strip opening and engaged with the gear teeth, a user may pull the strip and thereby cause the gear system to rotate the wheel so that the wheel spins and forces the vehicle to speed away from the launcher.Type: GrantFiled: January 26, 2006Date of Patent: November 4, 2008Assignee: JAKKS Pacific, IncorporatedInventors: Dominic Laurienzo, Brendon Vetuskey, Terence J Yukio Higuchi

Patent number: 7378050Abstract: A ceramic material powder for a translucent ceramic is molded with a binder, and the resulting green compact is embedded in a ceramic powder having the same composition with the ceramic material powder. After removing the binder, the green compact embedded in the ceramic powder is fired in an atmosphere having an oxygen concentration higher than that in the removal procedure of the binder and thereby yields a translucent ceramic represented by Formula I: Ba{(SnuZr1-u)xMgyTaz}vOw, Formula II: Ba(ZrxMgyTaz)vOw or Formula III: Ba{(SnuZr1-u)x(ZntMg1-t)yNbz}vOw. The translucent ceramic has a refractive index of 1.9 or more and is paraelectric.Type: GrantFiled: October 21, 2004Date of Patent: May 27, 2008Assignee: Murata Manufacturing Co., Ltd.Inventors: Nobuhiko Tanaka, Yukio Higuchi, Masayoshi Katsube, Mitsuru Sube

Patent number: 6018878Abstract: Detection of angles associated with wheel alignment of a vehicle can be carried out properly at all times according to the present wheel alignment examining apparatus irrespective of the size of a wheel to be examined. The present apparatus includes a sensor member (105, 106) pressed against a side surface of a wheel (11) to be examined and thus the sensor member rotates together with the wheel to be examined. Various inclination angles, such as toe, camber, caster and king pin angles, are detected from a displacement of the sensor member during its rotation. Use may be made of either a Cardan suspension mechanism or link mechanism for supporting the sensor member. When use is made of a link mechanism, toe and camber angles can be detected by the same encoder.Type: GrantFiled: November 21, 1997Date of Patent: February 1, 2000Assignee: Anzen Motor Car Co., Ltd.Inventors: Yutaka Fukuda, Yukio Higuchi, Ryoichi Abe
