Title: Throttle controller
Inventor: TERASAWA TEI
IPC: F02D9/02
Filed: 1991-02-21
Abstract: PURPOSE:To control electrification of an electromagnetic coil in response to a detected result by detecting a relative displacement between a member which interlocks to an acceleration operation mechanism and a member which interlocks to a throttle valve by means of a detection means easily adjustable due to its simple construction. CONSTITUTION:An operation plate 60 makes turning motion around an acceleration shaft 632 in response to operation of an acceleration pedal 7. A displacement is generated between a limit switch 80 and a cam 54 in response to differential movement between the operation plate 60 and a plate holder 50. When the rotational displacement of the plate holder 50 in relation to the acceleration plate 60 grows up to a prescribed rotational angle or more the limit switch 80 is operated by the cam 54, and electrification of an electromagnetic coil 20 is stopped. Consequently, a connection condition between a clutch plate 40 and a rotor 30 is released.

Filed: 1994-03-18
Abstract: PURPOSE:To manage lots of rings as a network by receiving information of a SONET bus via a ring and providing a path protection switch selecting a receiving end based on fault information to all nodes in the ring. CONSTITUTION:In the network provided with plural nodes in a ring 12 making optical communication, all nodes in the ring 12 are provided with a path protection switch 13 receiving information of a SONET bus via the ring 12 and selecting a receiving end upon the receipt of fault information.

IPC: B21J15/28
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To easily and correctly judge the quality of the caulked part of a rivet and a shaft by non-destruction. SOLUTION: Plate stocks 20 are joined with a rivet 7 (shaft 18, caulked part 19). A probe 8 is brought into close contact with the surface 21 of the plate stock 20 and a probe 10 is brought into close contact with the surface 19a of the caulked part 19. The pulse transmitted from the probe 8 is received with the probe 10 and the transmitting pulse is measured. Measuring is executed at plural positions around the shaft 18 (eight places every forty five degree or the like). When the pulse PA of a course A is received in the time TA and thereafter the pulse PB of a course B is received in the time TB, the joined part is judged to be normal (a). When only the pulse PB of the course B is measured, the joined part is judged to be the defective product having the floatation in the caulked part 19 or the inclined shaft 18 (b, c).  When neither pulse of the courses A and B is measured, the joined part is judged to be the defective product having loosening in the shaft 18 (d). When the pulse in a specified position (angle) is abnormal, the shaft 18 is judged to be diagonal in that direction.
