Title: Surface inspection equipment employing reverse reflection screen
Inventor: MORI YOSHIICHI
IPC: G01N21/88
Filed: 1992-11-05
Abstract: PURPOSE:To eliminate erroneous recognition in surface inspection by employing an imaging lens of camera having narrow focus depth and excluding a pseudo-image or a defective image from the range within the focus depth thereby discriminating between the defective image and the pseudo-image having different focal distance. CONSTITUTION:Light from a light source 4 is reflected on the surface of an object 5 to be inspected and enters into a reverse reflection screen 2 where the light is reflected in substantially the same direction as the incident optical axis and then reflected again on the surface of the object 5 to be captured by a camera 3. Since a pseudo-image produced as the virtual image of the defective image has focal distance (b) as compared with the focal distance (a) of the defective image, diaphragm 6a of an imaging lens 6 is fully opened and a narrow focal depth is set so that the pseudo- image is excluded from the range within the focal depth thus preventing the pseudo- image from being detected. Since the object 5 is illuminated with sufficient quantity of light, it is not susceptible to disturbance light and the excess quantity of incident light to the camera 3 due to fully opened diaphragm 6a is attenuated through a filter 7 loaded onto the front of the lens 6 thus sustaining an appropriate quantity of light.

Title: Digital information receiver and bit synchronization correction method
Inventor: ISHIDA IKUO
IPC: H04L7/10
Filed: 1992-11-06
Abstract: PURPOSE:To establish bit synchronization by correcting reception speed without affected by noises by measuring the deviation value between received information and a clock and correcting the clock based on the constant value when the value is constant. CONSTITUTION:When a counter measurement means 14 counts the constant value, it measures the value of a counter 12 which supplies clocks to a reception buffer 11 many times when an edge detection means 13 of reception information detects edges. When the measured count value is matched or within the range, a correction means 15 calculates the correction value of the counter, correcting the count value of the counter 12. Thus, the timing of the clock to be supplied to the reception buffer 11 is changed to be a middle point and the bit synchronization is corrected. In short, the clock is corrected based on the constant deviation only when the deviation value is constant and the bit synchronization is performed, resulting in elimination of noise influence.

Title: Virtual path connection system and method thereof
Inventor: FUJIMORI NARIHIKO
IPC: H04L12/721
Filed: 1994-11-30
Abstract: PURPOSE: To facilitate the maintenance of the up and down virtual paths(VP) by storing the information on the highways where one of both paths passes in the passing order and setting the other VP based on the information that is read out in the order that is adverse to the storing order. CONSTITUTION: A management object(MO) 2 connected to a virtual path(VP) sets an up VP transmission path based on the VP connection setting instruction of a connection MO 1 and informs of a VP connection numbers N. The MO 1 successively collects and stores the numbers N of the up VP transmission path. When the setting of the up VP transmission path is finished, the numbers N are read out in the adverse order and the MO 2 sets a down VP transmission path based on these read numbers. Then the MO 2 informs the MO 1 of a new number N and automatically sets a down transmission path to the same highway to complete its operation. Thus the VP connection is attained without increasing the load to a network system and the maintenance is facilitated for the highway-based switching operations, etc.
