Title: Current limiting control method for speed control device used in dc motor and speed control device for dc motor fitted with current limiting circuit
Inventor: NABATAME TERUAKI
IPC: H02H3/44
Filed: 1978-11-27
Abstract: PURPOSE: To prevent the flow of an excessively large current in the DC motor, by detecting the rise of the power supply voltage by utilizing the existence of phase difference between interline voltage and phase voltage and controlling so as to limit in advance the conduction angle of the phase control circuit.  
     CONSTITUTION: When the power supply voltage rises sharply, interline voltages e 1 , e 3 , e 5  having 30° phase lead rise, and e 5  becomes higher than output e 7  of peak maintaining circuit 11, which maintains peak value e 7  of e 6 , which is the resultant of the attenuation and rectification of phase voltage e 2  before the voltage rise. By this, the difference e 5 -e 7  is outputted from voltage comparator 15. As a result, phase angle clamping circuit 16 operates, and thereby the conduction angle of the switching element of power converter 5 is checked in advance.

IPC: G01N21/956
Filed: 1988-06-13
Abstract: PURPOSE:To make a pitch at the level of a signal by a colored periodic pattern short and to prevent the occurrence of moire by performing inspection based on image data obtained by picking up an image after the levels of the video signals of respective colors constituting the colored periodic pattern become equal. CONSTITUTION:Light sources 1a-1c for R, G and B are constituted so that they can respectively and independently adjust the intensity of light and an optical fiber bundle 3 obtained by bundling optical fibers 2a-2c which receive the light from the respective light sources is bundled so that the fibers of the respective colors are uniformly mixed at an outgoing port 4. By illuminating a sample 46 placed on an XY stage 50 with said fiber as a light source, the image is picked up with a television camera 41. While observing the video signals, the light quantities of R, G and B are adjusted so that the levels of the signals become equal in the respective colors and the spectrum of illuminating light is set. Thus, the colored periodic pattern can be inspected based on the image data obtained by irradiating the sample 46 having the colored periodic pattern with the light and picking up the image.

Title: Error detecting device for feeder on printed board work device
Inventor: ASAI KOUICHI
IPC: H05K3/00
Filed: 1991-05-22
Abstract: PURPOSE:To automatically detect the feeding errors of a feeder provided on a work device for applying work, adhesive application, etc., on a printed board. CONSTITUTION:A reference board provided with many reference marks is fixed to a Y-axial table in the same way as a printed board. A camera successively images the reference marks through each movement of the reference board and the camera moving in the X-axial direction. Thus, deviation amounts, DELTAxi, j, and deltaYi, j from the center of each image are measured (S2). Fixed errors, ex, ey, theta, to the Y-axial table of the reference board are calculated from these measured values, the moving command values of the camera, and the reference board, and the distance between the adjoining reference marks (S3, S4). Based on these errors and the above measured values, etc., the feeding errors, DELTAXi, j, DELTAyi, j of each feeder in the X-axial direction and the Y-axial direction are calculated by corresponding to the normal positions of the reference marks. The images of the reference marks and the calculation of the feeding errors are done eight times. Average values at each time are regarded as the feeding errors (S8).

Title: Endoscope device
Inventor: SEKIGUCHI TADASHI
IPC: A61B1/06
Filed: 1988-06-16
Abstract: PURPOSE:To compare a functional information image with a white light image readily by rotating and driving both filters in such a way that the transmitting monochromatic light of a first filter passes through a second filter whereas white light which has passed through the first filter goes through the white color attenuation area of the second filter, at the time of photographing the functional information image. CONSTITUTION:The first filter 1 has a transmitting area but also plural filter areas through which various monochromatic light are passed; the second filter 2 has the white light attenuation area and a transmitting area; and the filter 1 and 2 are rotated and driven by means of step motors 3 and 4, respectively. At the time of photographing the functional information image, the light intensity of a light source is increased by means of a light source controller 6, compared with the light intensity having at the time of photographing the white light image; the rotations of the motors 3 and 4 are synchronized so that the monochromatic light, which has passed through the filter areas of the first filter 1, goes through the transmitting area of the second filter 2 whereas the white light, which has passed through the transmitting area of the first filter 1, goes through the white light attenuation area of the second filter 2. Therefore, in the light coming into a light guide after passing through the second filter 2, there is not great difference in light intensity between the monochromatic light and white light.

Title: Reception synchronizing circuit
Inventor: TAKEMURA WATARU
IPC: H04L7/08
Filed: 1987-06-15
Abstract: PURPOSE:To establish the synchronization for a frame reception time of a prescribed sequence number of times at all times by providing a means computing a reception clock and restoring the counter to the initial state after the count is finished when a bit error in a received synchronizing bit string is detected. CONSTITUTION:If a bit error takes place in a synchronizing bit string after the synchronization is established, a control circuit 9 outputs a control signal (k), and an adder 7 computes the bit number being the subtraction of the bit number from the head of the synchronizing bit string till the bit with a synchronizing fault detected therefrom from the sub of the bit number of the synchronizing bit string and the bit number of the data bit string. Moreover, an error bit counter 8 receives the control signal (k) to allow the adder 7 to start count- down. Then when a control signal (m) reaches a low level, a control circuit 9 outputs a control signal (i) to prevent the bit number of the predetermined synchronizing bit string to the synchronizing bit counter 2 to start the count. Thus, only the synchronizing bit string is compared with the normal bit string and the synchronization is established for a frame reception time of a prescribed sequence number of times.
