Title: Ultrasonic wave proximity switch device
Inventor: SHINOURA SHINGO
IPC: G01S7/527
Filed: 1986-02-07
Abstract: PURPOSE:To prevent a proximity switch device from malfunctioning by repeating the transmission and reception of an ultrasonic wave within a specific time at a specific period. CONSTITUTION:A received signal and a received timing signal from a receiving circuit 10 are inputted to a NAND 16 and a flip-flop FF 17 is set to output a positive potential (a) and a zero potential (b); and a zero-potential signal is inputted to the U/D terminal of an up/down counter 18 and a pulse output from the terminal Q2 of a frequency divider 2 and the output of an FF 21 are passed through a NAND 20 and an inverter 22 to obtain positive-polarity pulses, which are applied to a terminal CK through a NAND 23 to perform adding operation. At this time, the device does not reacts unless the received wave continues by more than specific pulses, so even if a short-time external noise is received, the device does not malfunction. If there is a long-time external noise, the noise signal and a positive pulse Q5 are inputted to a NAND 29 to obtain a negative pulse, which sets the FF 21 to cut off the NAND 20, so that a counter 18 stops counting.

Filed: 1995-01-23
Abstract: PURPOSE: To provide a position coordinate calculating method which is similar to others by adjusting the width of the loop coil at a part corresponding to a position where the magnetic field produced by a position indicater varies. CONSTITUTION: An area is divided into an area where the intensity of the magnetic field produced by the position indicator is represented as e0, an area where it is represented as e1, and an area where it is represented as e2, and loop coils are arranged corresponding to the respective areas. Namely, the width of the loop coil corresponding to the area of e0 is w0, the width of the loop coil corresponding to the area of e1 is w1, and the width of the loop coil corresponding to the area of e2 is w2. They are related so that w1≈w2.e2/e1 and w0≈w1.e1/e0. Consequently, the tilt components of the straight areas of the output signals of the respective loop coils can be made nearly equal and the position calculating method which is similar to conventional examples can be utilized.

Title: Magnetic bearing controller
Inventor: NAKAJIMA MASAKAZU
IPC: G05D3/12
Filed: 1990-02-07
Abstract: PURPOSE:To improve the positioning accuracy of an axis by performing the switch between the output of a pseudo error signal generator and a position error signal consisting of the difference between a position command signal and the signal of a position sensor in accordance with the position of the axis. CONSTITUTION:A window comparator 8 outputs a signal to decide whether the output V of a position densor 4a is kept in a range of Vn<V<Vf or not. A pseudo error signal generator 10 receives the outputs A of the sensor 4a and the output B of the comparator 8 to produce two types of signals and outputs one of these two signals. If an axis 15 of a magnetic bearing is positioned out of a range of measurement to the position sensors 21 and 22, a changeover switch 9 conducts in a b-c section and is turned on at the side of the generator 10. A pseudo signal is produced when the position of the axis 15 is larger than a target position. Then the axis 15 moves in the direction where X is reduced. Meanwhile a position error signal consisting of the difference between a position error signal and a position command signal is outputted when the position of the axis 15 is smaller than the target position. Then the axis 15 moves in the direction where X is increased.

Abstract: PURPOSE:To perform the optimum traveling control of a vehicle in order to make the vehicle follow a target route by obtaining the target control value with which the vehicle can follow the target route and setting the vehicle to be controlled at the steering angle of the vehicle with the target control value defined as the steering angle correction value respectively. CONSTITUTION:The input image sent from an image pickup part 1 which photographs the surface of the frontward road of a vehicle is differentiated by an image processing part 2 to undergo the detection of its edge. Then the optimum threshold value is automatically set by an automatic threshold value setting circuit of the part 2 and according to the gradation of the input image. Then the edge image is binarized. Based on this processed image, the X-Y coordinates are converted into the rho-theta coordinates. Thus the continuous segment information on the road edge are obtained. A travel enable area recognizing part 3 applies the projection conversion processing to the relevant image and recognizes the area between the continuous road edges as a travel enable area of the vehicle. A target route setting part 4 sets a target route on the recognized road as an optimum traveling route. A control part 5 sets the target control value and obtains the steering angle correction value for traveling of the vehicle on the target road to define that correction value as the target control value for traveling control of the vehicle.

Patent JP-S50130476-A (JP)
IPC: G04B19/00
Filed: 1975-03-11
Abstract: As time-indicating members the clock comprises a lower fixed disc (418) having twelve successive, sector-shaped surface regions and above this a rotating disc having a window (422), it being possible to make out the sector-shaped surface regions through the window. The fixed disc projects radially beyond the rotating disc and in its projecting ring region bears an interpolation scale. By simultaneously perceiving the angular position of the window and the colour, the allocation of certain colours to certain times can be learnt. The interpolation scale allows the intervening times between successive full hours to be established. In order to implement the principle of colour time even more logically and to further facilitate the learning of the allocation of certain colours to certain times, the interpolation scale is formed by radially outer edge regions of the sector-shaped surface regions (424a to m) of different colours projecting radially over the edge of the driven disc (420). <IMAGE>
