Filed: 1990-05-25
Abstract: PURPOSE:To inspect a surface flaw of a sphere efficiently without repetition by receiving reflected light from the surface of the rotating sphere, which is picked up while the surface of the sphere is irradiated with light, as a two-dimensional image. CONSTITUTION:The light from a light source 5 is directed 6 downward at right angles and projected on the sphere on a conveyance rotary part 2 and its reflected light is picked up 7 at specific timing and inputted to the image processor 8 of an inspection part 4. At this time, a control signal is sent synchronously from the processor 8 to a control part 3 and an image pickup camera 7 and the rotary part 2 is controlled so that image pickup positions on the surface of the sphere 1 do not overlap with each other. The image signal which is inputted to the processor 8 is passed through an A/D conversion part 11 and an image memory 12 and after mask processing 13, a brightness correcting device 14 subtracts a brightness reference image signal and outputs a difference signal. This signal is converted into a binary signal with a constant threshold value and extracted 15 as a flaw signal in a flaw inspection area and a noise is removed 16, so that the signal is outputted as a flaw presence signal. When there is no flaw signal, a next image is inputted without any overlap between image pickup positions, and similar flaw detection is performed.

Title: Modem for fully double communication
Inventor: SHINADA SHIGEO
IPC: H04L5/14
Filed: 1981-09-03
Abstract: PURPOSE:To give no effect to the rewriting of transmission data due to synchronizing action, by switching the transmission and reception or a modulating process at a moment when the value of a counter which counts the modulating and demodulating frequencies at a signal processing part reaches a prescribed level. CONSTITUTION:Counters 13 and 14 that count modulating and demodulating frequencies respectively are added to a signal processing part 10. The transmission/ reception or the modulating process is switched when the value of either the counter 13 or 14 reaches a prescribed level. Thus a prescribed process is carried out in a desired cycle regardless of the extension of the receiving timing clock due to synchronizing action. Thus no effect is given to the rewriting of the transmission/reception data. As a result, the occurrence can be prevented for a data error since no effect is given to the writing of the transmission/reception data due to the synchronizing action.

IPC: G06F21/62
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain an access control system capable of executing the access control of safe objects in respect of access control between plural objects. SOLUTION: In the access control system, a user ID 204, a password 206 and preparation time 208 are added to an access descriptor 202 to be used for access control and stored in both of an object accessing an accessed object and the accessed object as generation information. When the access descriptor including the generation information does not coincide with the other one and an access can not be permitted, only the generation information is returned to the object. Since the accessing object outputs an access request again by a password corresponding to the returned generation information, flexible and safe access control can be executed.
