Title: Control device for dc motor
Inventor: TANAKA KEIKICHI
IPC: H02P5/68
Filed: 1981-02-28
Abstract: PURPOSE:To perform stable control at the all-speed regions of DC motors by a method wherein the balance control of load currents or the amplification factor of a ratio control amplifier is inversely proportional to the speed of the DC motors and the closed loop amplification factor of a control system may not be varied. CONSTITUTION:A voltage is applied to DC motors 2A, 2B by a command control power supply 1 to flow load currents IA, IB to the DC motors 2A, 2B for balance or ratio operation. If the load current IA increases and the balance or ratio is disturbed due to some reason, a current detection signal IA' detected by a current detecting device 7A increases and the balance control for the load currents or the control output signal EA of a ratio control amplifier 8 intensifies the field current of the DC motor 2A by the signal to control the load current IA toward the decreased direction. Meanwhile, a control output EB decreases the field current of the DC motor 2B to control the load current IB toward the increased direction and for arriving at predetermined balance or ratio.

IPC: G11B7/09
Filed: 1987-02-10
Abstract: PURPOSE:To suppress resonance in the longitudinal direction and to minimize sharpness at a low resonance frequency level by providing a supporting member with flexible parts to be optionally flexed in both the longitudinal and vertical directions. CONSTITUTION:One end 41 of the supporting member 7 is fixed to a movable body, the other end 41 is fixed to a fixed body and both the end parts 41 are connected by a coupling member 43. The flexible parts 42 are formed in the vicinity of respective end parts 41 of the coupling part 43. The flexible parts 42 are formed so as to be flexed in the longitudinal direction of the coupling part 43 and at least one direction approximately vertical to the longitudinal direction. Even if the supporting member 7 is moved any one of three directions, i.e. longitudinal, right and left directions, the flexible parts 42 are correspondingly displaced. Since damping bodies 27 are fitted to the flexible parts 42, vibration in any direction can be also suppressed. Thus, resonance in the longitudinal direction can be suppressed and sharpness at a low resonance frequency level can be reduced.

Abstract: PURPOSE:To make steering torque in magnitude commensurate to surface load generable by installing a surface load detecting means which detects magnitude of the surface load, and controlling a steering ratio changing means so as to change a steering ratio at the time of rest swing according to the detected surface load. CONSTITUTION:In a steering gear provided with a steering ratio changing means A, changing the ratio of a steering angle of a steering wheel to an actual steering angle of a steering control wheel, there is provided with a surface load detecting means B which detects magnitude of surface load being added to the steering control wheel in corresponding to steering control at the time of rest swing of the steering control wheel.

In brief, while the surface load is not so large enough, the steering ratio is made smaller, and such an action as building up steering torque in the steering wheel is made smaller as well, and when the surface load becomes larger, the steering ratio is made larger and thereby this action for building up the steering torque is controlled so as to make it larger as well.

Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a recording and reproducing device using the EPRML system with higher accuracy in using the technology of the PRML system as it is by performing a specific decoding processing on a filter output obtained by precoding processing as exactly the same as the PRML system. SOLUTION: In this EPRML (EPR 4: expanding partial response class 4 and viterbi decoding system), the precoding processing 13 that is exactly the same as the PRML (partial response class 4 and viterbi decoding system) is performed from an encoder 11 to a filter 20. Now, output of the filter 20 is (1+D)-processed 21 to obtain output signal of the EPR 4. Then, viterbi decoding processing of 1/(1+D) is performed in a viterbi 22 and a decoder 12 to output a reproducing data. Thus, by using encoding and decoding technology, gain control technology and timing control technology in the PRML system as they are using the EPRML system higher than the PRML system in performance, the recording and reproducing device with higher accuracy is inexpensively provided.

Title: Matrix display device
Inventor: KOFUJITA HIROSHI
IPC: B21D28/00
Filed: 1978-03-14
Abstract: PURPOSE: To enable the progress and results of judgement by two kinds of information to be accurately displayed by dividing the matrix form plate surface composed  of photo display element groups to the 1st to 4th AND condition regions.  
     CONSTITUTION: First, the display element 2 of (0, 0) of a matrix display plate 1 makes photo display. When the integrated value of the vibration waveform of a press blanking out, e.g., a steel plate, exceeds the specified value 1 at the time t 1 , the t 2 , the photo display shifts to (0,1). When the integrated value again exceeds I  and at the same time the peak value of the waveform exceeds the threshold level P  at the time photo display shifts to (1, 2). In the similar manner, the photo display  subsequently shifts and at the time t 7  it displays (4, 6). Now, if the photo display is  in the first condition region A of the position within boundary lines 3, 4, it indicates that the blanking operation of the press is in a normal or allowable range and if it is in the second condition region B by exceeding the line 4, it is within the allowable range in terms of the peak value but is anomalous in terms of the integrated value. When the time T passes by, the plate 1 is reset and the similar displaying is accomplished during the next time T.

Title: Optical particle analyzer provided with two kinds of light sources
Inventor: FUKUDA MASAKAZU
IPC: G01N33/49
Filed: 1990-02-08
Abstract: PURPOSE:To reduce the size and cost of the analyzer by using a scattered light signal as the timing signal when a fluorescent signal is processed. CONSTITUTION:A laser beam is condensed by an irradiation optical system 12, the wavelength of the lamp light is selected, and the light is condenses by an irradiation optical system 28 to irradiate the sample trickle region of a flow cell 22. A fluorescence-dyed blood corpuscle is passed through the crossed irradiation region, and scattered light and fluorescence are emitted. Accordingly, the scattered light and fluorescence of one particle are detected at the same place and timing. Since the laser beam is thinly converged and has a single peak, the scattered light is also used as a peak signal. As the value for the fluorescence signal is detected by using the scattered light as the timing signal, a fluorescence signal correlated with the fluorescence amt. emitted from the particle is detected even if the intensity distribution of the lamp light is not uniform.

Abstract: PURPOSE:To obtain a low noise vacuum cleaner without damaging cleaning ability by making the rotating speed of a fan motor maximum when a signal is outputted from a floor nozzle operation detecting means and lowering the rotating speed of the fan motor when the signal is not outputted. CONSTITUTION:When a fan motor 5 and a brush motor 8 are operated and a floor nozzle 7 is pressed on a cleaning surface and moved back and forth, a ball 9b in a floor nozzle operation detecting means 9 is moved back and forth along a guide part 9a and the optical path of a light emission part 9d and a photo-detection part 9c is interrupted. When the ball 9b interrupts the optical path, the output of the detection part 9a is the pulse output of an H level and in the other case, the output is the pulse output of an L level. When cleaning is stopped, the floor nozzle 7 is stopped and the ball 9b is stopped on the optical path of the light emission part 9d and photo- detection part 9c or in an area excepting for the optical path. Then, the output of a detection part 9e is the fixed output of the H or L level. when the output of the floor nozzle operation detecting means 9 is the pulse output, a control circuit 3 judges that the cleaning is just executed. Then, the rotating speed of the brush motor 8 and fan motor 5 is made maximum and when the output is the fixed output, it is judged that the cleaning is just stopped. Then, the rotating speed of the brush motor 8 and fan motor 5 is made half.
