Patent number: 5718114Abstract: The one-way clutch mechanism of a torque converter which has a short axial dimension, and which neither produces a shock noise (an abnormal sound) nor suffers a power loss in the idle mode thereof. An outer race (30 in FIG. 1 ) is united with a stator (18), and supports the stator (18) so as to be axially movable and rotatable with respect to a stationary shaft (16). The outer race (30) includes a first side face (32) which is formed with first teeth. An inner race (40) is united with the stationary shaft (16), and includes a second side face (42) opposite to the first side face (32). The second side face (42) is formed with second teeth which can prohibit the rotation of the outer race (30) in one direction, by meshing with the first teeth. The stator (18) and the outer race (30) receive the axial component force of a fluid stream which changes depending upon a speed ratio.Type: GrantFiled: July 10, 1996Date of Patent: February 17, 1998Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kiyohito Murata, Shogo Matsumoto, Hiroyuki Shioiri

Patent number: 5701983Abstract: A clutch device with a cam mechanism is provided, which is free from drag loss when the phase is switched from a state wherein the cam mechanism is operative to a state wherein it is inoperative. A cam groove 1c and a recess 1d are formed on the inner surface 1a of a piston, and a cam groove 3c and a projection 3d to be inserted into the recess 1d are formed on the inner surface 3a of a pressure plate 3. Between the cam grooves 1c and the 3c is interposed a cam roller 2 loosely retained by a roller cage 4. When the hydraulic pressure is applied to the back surface 1b of the piston 1 while a C.sub.3 clutch disk 5 rotates faster than the piston 1, the cam mechanism is operative to carry out the engagement operation. On the contrary, when the application of the hydraulic pressure is interrupted while the C.sub.3 clutch disk 5 rotates slower than the piston 1, the engagement is released. Meanwhile, the riding of the cam roller 2 over the cam elements is avoidable by the recess 1d and the projection 3d.Type: GrantFiled: February 12, 1996Date of Patent: December 30, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shogo Matsumoto, Kiyohito Murata

Patent number: 5695032Abstract: A flywheel (FW) includes a front cover as a first mass member (102), an inner plate as a second mass member (104), and a coiled spring as a damper member (106) which is interposed between the first and second mass members. A clutch or a clutch body (108) is disposed so as to be connectible with and disconnectible from the inner plate (104) by hydraulic pressures (P0, P1). The front cover (102) and the inner plate (104) are united through a friction plate as coupling means (110) by the hydraulic pressures (P0, P1) for connecting and disconnecting the clutch (108). Thus, the first and second mass members (102, 104) can be united by the simple construction of low cost. Furthermore the uniting operation, inclusive of its synchronization with the control of the clutch body (108), can be precisely controlled.Type: GrantFiled: July 31, 1996Date of Patent: December 9, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kiyohito Murata, Hiroyuki Shioiri, Shogo Matsumoto

Patent number: 5638933Abstract: This clutch device has a first cam mechanism and a second cam mechanism disposed on a relatively rotatable a pair of members. When the first cam mechanism is pushed by a piston to one of the pair of members rotating in a direction, the first cam mechanism generates a thrust force corresponding to an input torque and thereby the relatively rotating members are engaged. When the second cam mechanism is pushed by a piston to one of the pair of members rotating in a reverse direction, the second cam mechanism generates a thrust force corresponding to the pushing force of the piston, and thereby the relatively rotating members are engaged. A return spring giving a biasing force to separate the second cam member from the one of relatively rotating member is designed not to reduce the thrust force generated by the first cam member during the action of the first cam mechanism.Type: GrantFiled: March 20, 1996Date of Patent: June 17, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shogo Matsumoto, Kiyohito Murata

Patent number: 5456343Abstract: A wet type clutch which has its piston moved by the difference of the pressure in two oil chambers at the two sides of the piston while shutting the communication between the two oil chambers with a friction member adhered to either of the piston or a front cover to be engaged by the piston. An annular groove for communicating with such one of the two oil chambers as will take a lower pressure when the clutch is applied is formed in the surface, to which the friction member is adhered, and/or the adhered surface of the friction member itself, to reduce the pressure acting to return the piston. A seal or high porosity material may also be used to reduce the oil pressure acting on the piston.Type: GrantFiled: March 31, 1994Date of Patent: October 10, 1995Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kiyohito Murata, Shogo Matsumoto

Patent number: 5162838Abstract: A facsimile apparatus has a transparent plate on which a document may be located. The document is then scanned by a scanner which includes electronic solid state light generation means e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector. An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternately, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the storage. The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner fixed.Type: GrantFiled: July 24, 1991Date of Patent: November 10, 1992Assignee: Hitachi, Ltd.Inventors: Tatsuki Inuzuka, Keisuke Nakashima, Toru Takei, Yasuyuki Kojima, Kyoichi Nomura, Shinichi Shinoda, Katsubumi Ouchi, Hideki Muroya, Eizou Ebisui, Norikazu Takahashi, Tomoe Sasayama, Hideo Nakazawa, Naoki Kinoshita, Yasunori Iwafuji, Takeshi Kobayashi, Hisashi Matsumoto, Hiroshi Kawamura, Tadashi Tamaoki, Shogo Matsumoto, Kenji Yokoi, Atuhiko Urusihara
