Title: Axle detector
Inventor: UEDA CHUICHI
IPC: G01C3/06
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of axle detection by constituting the axle detector so that the moving distance (the interval of a reflecting position) of an irradiation point in each pulse period of pulse light is sufficiently smaller than the cross-sectional height of a tire. SOLUTION: The width of a road is set up as L and it is supposed that a vehicle 24 of body width W passes a position most separated from an axle detector 21 arranged on the roadside 23 of the road at a vehicle speed V[m/sec]. When it is defined that a distance from the light projection part of the axle detector 21 up to a tire 48 is D[m] (D>-w) and the light emitting interval angle of pulse light projected from the detector 21 is Δθ [rad], the interval Δh[m] of the reflecting position of pulse light projected from the detector 21 on the tire 48 can be approximately expressed by Δh=D.Δθ.  Thereby the interval Δh of the reflecting position of the pulse light is made sufficiently smaller than the cross-sectional height (a value obtained by subtracting the radius of an inner periphery from the radius of an outer periphery) of the tire 48 in order to improve the detection accuracy of the tire 48.

Title: Signal detection circuit
Inventor: ICHIKAWA HIROSHI
IPC: H03D1/00
Filed: 1991-07-29
Abstract: PURPOSE:To allow the circuit to trace a fluctuation of a desired signal frequency by realizing an equivalent band pass filter depending on a cut-off frequency of a differential output low pass filter. CONSTITUTION:An n-phase signal generating means 2 receiving an output of a clock generating means 1 outputs an n-phase signal having the same frequency as that of a detected signal, and a high signal component is attenuated by a differential output low pass filter group 4. Thus, a DC signal proportional to an amplitude of a desired signal component in the detected signal is obtained at the output. Since the output of each differential output low pass filter is deviated in response to the phase of the output of the n-phase signal generating means 2, a maximum value of each set in the n-set of output is obtained by a maximum circuit group 5, the total sum of the outputs is obtained at an adder 6 and a prescribed number of multiple of the output is outputted to an attenuator 7. Then a maximum value detection means 8 obtains the maximum value in the output from the attenuator 7 and in the output of the maximum value circuit group 5. Thus, fluctuation of the level due to a phase of a desired signal is suppressed.

Filed: 1987-07-30
Abstract: PURPOSE:To realize the work shift control at a high speed and with high accuracy with use of a small memory capacity by controlling both position and speed gains of a control system in response to the attitude and the speed of a robot for smooth changes of both gains. CONSTITUTION:In a position feedback control system including a speed control loop serving as a minor loop, not only the speed gain Gv but the position gain Gp is handled as the variables. These variables are defined as the prescribed functions of the positions of actuators M1-M6 respectively. Thus both gains Gv and Gp are set in consideration of the change of the moment of inertia of each joint. These gains Gv and Gp are stored in memories N1-N6 in the form of simple functions. Then these gains are smoothly changed in response to the attitude and the speed of a robot. Thus the satisfactory servo response characteristics are secured over an entire working area of the robot. As a result, a smooth working action of the robot is attained at a high speed and with high accuracy with use of a small memory capacity.

Title: Grinding device for surface of magnetic disk
Inventor: NISHIGUCHI TAKASHI
IPC: G11B5/84
Filed: 1982-10-29
Abstract: PURPOSE:To remove fine protubelances on the surface of a disk for a disk memory thereby to attain the maintenance of a good magnetic characteristic of the disk to cope with the required higher recording density, by providing a cutting tool for a vanish slider with a diamond edge and making the cutting tool edge in a sharp form. CONSTITUTION:Grinding is carried out with a disk 7 rotating at a slow speed and a block 9 of a vanishing slider 10 applied to the disk very slightly afloat thereon. Since, here, the rotating speed of the disk 7 is low, if a minor protuberance B< the radius of curvature R of the cutting tool edge 11, the cutting tool edge 11 ascends the protuberance 8b to go over the same, and several repetitions are required to reduce the same. If B>R, on the contrary, the protuberance 8b is cut away by the cutting tool edge 11. In the experiments, protuberances higher than 0.03mum were all removed by 3 times of seeking and protuberances lower than that also were cut down according to the seeking times. By removing minor protuberances on the surface as described above, a spattered disk is made capable of coping with the required higher recording density and a magnetic disk without any deficiency in the magnetic characteristic can thus be provided.

In this way, reduction of a wide range of vibration can be achieved without remarkably increasing the driving force of a inertia mass and the stroke thereof. And hence, the apparatus can be made compact.
