Title: Electric power steering with learning function
Inventor: NAGAI MICHIYUKI
IPC: B62D113/00
Filed: 1993-11-08
Abstract: PURPOSE:To suppress the error of the neutral position of a steering angle sensor and narrow the control dead zone by averaging the output values of the steering angle sensor, and correcting the average value as the neutral output value of the steering angle sensor on condition that a vehicle is straightly advanced. CONSTITUTION:This electric power steering is provided with a torque sensor 5 detecting the steering force of a steering shaft 11, a steering angle sensor 6 detecting the steering angle of the steering shaft 11, and a motor 1 connected to a steering rack 10 via a reduction gear 3. A controller 8 judges that a vehicle is straightly advanced in response to the detected steering force and steering angle. The controller 8 averages the output values from the steering angle sensor 5 for a fixed period and calculates this average value as the neutral output value of the steering sensor 5 on condition that the vehicle is straightly advanced. The control dead zone is corrected to be narrowed to the utmost possible centering on the neutral output value thus obtained by learning. The returning performance of a steering wheel is improved, and good steering feeling is obtained.

Title: Safety device of high strength bolt joint portion
Inventor: TAKAHASHI YASUHIKO
IPC: F16B5/02
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent a breakage of a high strength bolt even by a vibration of not less than an acceptable relative moving quantity by forming a through-hole of a high strength bolt into a long hole to from a joining portion having a friction damper function and providing a low strength zone broken by the high strength bolt on both ends of the long hole. SOLUTION: A building structure is distorted by an earthquake and a longitudinal force of a long hole 14a is applied to a joining portion and when the force exceeds a stationary friction force of a friction damper, outer plates 10, 12 and an intermediate plate 14 slides and relatively moves on a friction plate 22 interposed therebetween. A high strength bolt 16 also relatively moves in a long hole 14a and a vibration energy is damped by a friction force. When a vibration is large and becomes larger than an acceptable moving quantity of the bolt 16, the bolt 16 is abutted to an end of the long hole 14a and a shearing force is applied to the bolt 16. However, since the vicinity of the end of the long hole 14a is a fragile low strength zone 26 in a hole 14b, this zone 26 is destroyed prior to a breakage of the bolt 16.  Thereby, the vibration is damped and the bolt 16 is abutted to the hole portion 16b to be locked. Thereby, a separation of the joining portion of the building frame can be prevented and the vibration of the building can be also inhibited.

Title: Boring device for printed wiring board
Inventor: INAGAWA HIDEHO
IPC: B23K26/382
Filed: 1989-10-27
Abstract: PURPOSE:To execute good boring efficiently from both surfaces by having means for guiding the laser beams projected from two laser light sources from both surfaces with respect to the processing position of a printed wiring board. CONSTITUTION:The laser beam of the laser 2 is reflected by a mirror 12 and is condensed by a condenser lens 8 so as to form a spot on the front surface side of the printed wiring board 16. The laser beam from the laser 4 is reflected by a mirror 14 and is condensed by a lens 10 so as to form a spot on the rear surface side of the printed wiring board 16. The angles of deflection of the laser beams by the mirrors are both 90 deg. and the reflected light rays thereof progress in the directions opposite from each other in the same direction. The adjustment to align the optical axes of the two reflected light rays is executed by moving the laser 4 and a sensor 18 in an arrow direction with respect to a base plate 24 while the printed wiring board 16 is not mounted and detecting the laser beam projected from a reference light source 6 by the sensor 18. The good boring is executed efficiently from both surfaces in this way.

Title: Pressure control valve
Inventor: TAKEUCHI YUKIHIKO
IPC: F02M25/08
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of noises caused by repetitive opening and closing of a valve body of a pressure control valve. SOLUTION: A valve chamber 33 housing a valve body 4 which closes a valve chamber side opening 32a of a canister port chamber 32 is divided into a first chamber 331 containing a valve surface 4a of the valve body 4 as a chamber wall surface, and a second chamber 332 containing a back surface 4b as a chamber wall surface. The chambers 331, 332 are respectively communicated with a fuel tank port chamber 31. Especially, the second chamber 332 is communicated with the fuel tank port chamber 31 through a throttle flow passage 4023. When negative pressure inside the fuel tank port chamber 31 is increased and the valve body 4 is opened, air is flowed from the canister port chamber 32 to the fuel tank port chamber 31.  Even in the case that the negative pressure on an immediately downstream part of the valve body 4 is lowered, at this time, valve closing is retarded by decreasing the speed of negative pressure reduction at the back surface 4b of the valve body 4 due to function of the throttle flow passage 4023. Short cycle closing of the valve body 4 is thus avoided.

IPC: G03G15/16
Filed: 1989-10-27
Abstract: PURPOSE:To enable the excellent transfer of a toner image irrelevantly to humidity by isolating and separating or short-circuiting 1st and 2nd paper guides from or to an earthing part according to the humidity. CONSTITUTION:The 1st and 2nd paper guides 3 and 7 are connected in common and grounded to the earthing part 12 through a changeover switch 11. The contact point of the changeover switch 11 is switched according to the humidity and the changeover switch 11 is placed on the ON side at high humidity or in a high-humidity area to isolate and separate the paper guides 3a and 3b, and 7 from the earthing part. Therefore, corona discharge charges which operate from behind a copying machine 4 are prevented from flowing to the earthing part 12. At normal humidity or in a normal humidity area, the changeover switch 11 is connected to the OFF side and consequently a potential difference which is large enough to cause discharge between copying paper 4 or the paper guides 3a and 3b, and 7, and the earthing part 12. Consequently, the toner image transfer device which can transfer the toner image excellently without being affected by the humidity is obtained.
