Publication number: 20080099000Abstract: A PCV valve include a housing which internally has a valve chamber including an entrance at one end and an exit at the other end in an axial direction of the valve chamber. In the valve chamber, a valve element which is axially movable and a spring which urges the valve element toward the entrance are provided. An electric heater is provided in the housing. The valve element includes an end which is movable close to the entrance. The electric heater is arranged in such a manner as to surround the valve chamber from the exit to the end of the valve element closer to the entrance. The electric heater includes a cylindrical bobbin made of a high heat-conductive material and a coil wound on the outer periphery of the bobbin. The bobbin has an inner peripheral surface forming a large part of an inner peripheral surface of the valve chamber.Type: ApplicationFiled: October 10, 2007Publication date: May 1, 2008Applicant: AISAN KOGYO KABUSHIKI KAISHAInventors: Koichi Suzuki, Mamoru Tateishi, Katsumi Ishida, Hiroshi Asanuma, Hirokazu Konohara, Hideto Ide

Patent number: 6057515Abstract: Disclosed is the powder feeder in which the duty ratio X.sub.T corresponding to the target feed amount Q.sub.T is calculated on the basis of the calibration curve obtained by the feeder calibration which is conducted before the start of powder feed, and the powder P starts to be fed according to the duty ratio X.sub.T, therefore, the actual feed amount can reach to the target feed amount Q.sub.T in a short time (within the time T.sub.1) from the start of powder feed, and the powder P can be fed while controlling the actual feed amount with high accuracy, and further the powder P can be precisely fed even in case of the short time feed for several seconds.Type: GrantFiled: May 10, 1999Date of Patent: May 2, 2000Assignee: Aisan Kogyo Kabushiki KaishaInventors: Katsumi Murai, Mamoru Tateishi, Masaki Ikeya

Patent number: 5938075Abstract: This invention provides a method for driving intermittently a vibrator having a resonance frequency with the resonance frequency in which the vibration of the resonance frequency is attenuated promptly after the ending of driving with the resonance frequency and the vibration of the resonance frequency increases promptly after the starting of driving with the resonance frequency. Further, this invention provides a method for driving powder feeders using ultrasonic motors which are easy to control powder feed rates and further provides powder feeders. A powder feed pipe is attached to an ultrasonic motor the end of which is elliptically vibrated with the resonance frequency, and powder P is fed from the hopper body when AC voltages of the resonance frequency and non-resonance frequency are applied alternately to the piezoelectric element 1 of the ultrasonic motor.Type: GrantFiled: May 13, 1997Date of Patent: August 17, 1999Assignee: Aisan Kogyo Kabushiki KaishaInventors: Katsumi Murai, Mamoru Tateishi, Masaki Ikeya

Patent number: 4884052Abstract: A sliding contact includes a sliding contact piece having a contact segment and fixed to a snap member extending perpendicularly to the contact segment. The snap member has at least two snap portions formed in alignment perpendicular to the contact segments including one adjacent the contact segments which is adapted to be concentrically fitted onto a mounting projection of a slider and another apart from the contact segments which is adapted to keep the angle of the contact segments to the slider. Also, there is a connecting contact with at least two holding arms for nipping therebetween a substrate on both sides thereof, at least one of the holding arms having a projection to be inserted in a hole or recess preliminarily formed in the substrate. After the projection is received in the hole or recess, it is fixed by a conductive anchoring material such as solder, so that the connecting contact may be fixedly attached to the substrate.Type: GrantFiled: May 26, 1988Date of Patent: November 28, 1989Assignee: Aisan Kogyo KabushikiInventors: Kenji Eitoku, Mamoru Tateishi, Kenji Hayashi
