Patent number: 9044697Abstract: An oil strainer includes a body having first and a second tubular member. One end of an outlet side tubular member has an inner diameter larger than the outer diameter of one end of an inlet side tubular member. The inner periphery of the one end of the outlet side tubular member includes a fusion bonding part, a shoulder closer to the one end of the outlet side tubular member than the fusion bonding part and another shoulder closer to the other end of the outlet side tubular member than the fusion bonding part. The outer periphery of the one end of the inlet side tubular member includes a fusion bonding part, a shoulder closer to the one end of the inlet side tubular member than the fusion bonding part and another shoulder closer to the other end of the inlet side tubular member than the fusion bonding part.Type: GrantFiled: September 27, 2007Date of Patent: June 2, 2015Assignee: DaikyoNishikawa CorporationInventors: Satoshi Enokida, Atsushi Yuki, Toshiya Kaneyasu

Patent number: 8635983Abstract: An oil pan 1 includes: an oil pan body 2 having a reservoir 21 for storing oil circulated in an engine E and returned to the reservoir 21; and a separator 3 having a vertically extending sidewall unit 4 partitioning the reservoir 21 into a first reservoir 21a for storing high-temperature oil and a second reservoir 21b for storing low-temperature oil. The first reservoir 21a has a suction-member-placement region 22 in which a member for sucking oil is provided. The separator 3 has an inclined portion 61 extending, to the suction-member-placement region 22, from a portion below a downstream end of a return pipe Rt for allowing oil to return to the first reservoir 21a.Type: GrantFiled: February 9, 2010Date of Patent: January 28, 2014Assignee: DaikyoNishikawa CorporationInventor: Satoshi Enokida

Patent number: 7799155Abstract: A reliable and superior joining strength in entire joining parts of resin molded bodies including tilting portions is obtained by devising a shape and a size of each protrusion for welding provided in the joining parts of the resin molded bodies. The joining parts of upper and lower half bodies 10 and 20 have vertical portions 11 and 13 and vertical portions 21 and 23 respectively vertical to a pressurizing direction and tilting portions 12 and 22 tilting relative to the pressurizing direction, and protrusions for welding 11E to 13E or 21E to 23E are provided in at least the joining part of one of the half bodies. Further, referring to a butting area of the protrusions in a butted state, the butting area in the vertical portions is set to be less than the butting area in the tilting portions.Type: GrantFiled: March 12, 2008Date of Patent: September 21, 2010Assignee: Daikyonishikawa CorporationInventors: Satoshi Enokida, Koichi Fujikawa

Patent number: 7581522Abstract: Upper and lower split components include upper and lower concave parts, respectively, forming the inner periphery of an intake pipe. An internal pipe is placed between the upper and lower concave parts. The upper concave part is formed a distance away from the outer periphery of the internal pipe. The outer periphery of the internal pipe is provided with a fitting part fitted into the lower concave part and a sealing part accommodated in an accommodation recess formed in the upper concave part. The inner face of the accommodation recess and the sealing part are formed along the direction of vibration of vibration welding and are in contact with each other.Type: GrantFiled: December 20, 2007Date of Patent: September 1, 2009Assignee: DaikyoNishikawa CorporationInventor: Satoshi Enokida

Publication number: 20080156412Abstract: A reliable and superior joining strength in entire joining parts of resin molded bodies including tilting portions is obtained by devising a shape and a size of each protrusion for welding provided in the joining parts of the resin molded bodies. In a structure of joining resin molded bodies according to the present invention, upper and lower half bodies 10 and 20 are joined with each other by means of a vibration welding method while the upper and lower half bodies 10 and 20 are being pressurized in a state in which joining parts thereof are butted into each other in a substantially entire area of the joining parts. The joining parts of the respective half bodies have vertical portions 11 and 13 and vertical portions 21 and 23 respectively vertical to a pressurizing direction and tilting portions 12 and 22 tilting relative to the pressurizing direction, and protrusions for welding 11E to 13E or 21E to 23E are provided in at least the joining part of one of the half bodies.Type: ApplicationFiled: March 12, 2008Publication date: July 3, 2008Applicant: DAIKYONISHIKAWA CORPORATIONInventors: Satoshi Enokida, Koichi Fujikawa
