IPC: H04N5/225
Filed: 1991-05-17
Abstract: PURPOSE:To prevent the misdispatch of a guardian and to reduce line capacity by finding out the height of the centroid of a moving object, and only at the time of judging that the moving object is a human body based upon the height of the centroid, transmitting an image to a central monitoring center. CONSTITUTION:An image processing part 6 takes in a background image through a camera 1, and when a change is generated in the image, regards the change as the appearance of a moving object and removes the background. Then the many-valued image of only the moving object is binarized and labeling processing is applied to the binary image to find out the area of the moving object. When a difference between the obtained area value and the area value of an image obtained immediately after is less than a prescribed value, the existence of the moving object in a monitoring area is judged and its centroid is calculated. Only when the height of the centroid is included within a fixed range corresponding to the height of the centroid of a human body, an alarm and an image of an invader are sent from a transmitting equipment to the monitoring center through a communication line 9. Consequently the generation of a misalarm due to a non-organism, an inanimate object a small animal, or the like can be prevented.

Title: Numerical number control unit
Inventor: ENOMOTO MINORU
IPC: B24B49/00
Filed: 1978-11-16
Abstract: PURPOSE: To ensure the setting of both the floating and fixed coordinate systems, thus realizing the selective use for the positioning of both coordinate systems through the program.  
     CONSTITUTION: No constant measurement signal is delivered even though the position of the grindstone's grinding surface varies dut to the wear caused by the grindstone and thus the grindstone stage is sent up to the zero point of coordinate system A. As a result, shift α is produced between the zero point of system A and feed stop position a 4  controlled by the constant measurement signal. Thus in the next cycle, the speed switching must be given at positions a 1 ', a 2 ' and a 3 ' where the correction is given to speed conversion points a 1 , a 2  and a 3  each by the amount equivalent to shift α. Accordingly, new coordinate system B is set up with feed stop position a 4  controlled by the constant measurement signal used as the original point. Thus system B is designated for start of the next cycle, and the feed is controlled by command value N 1 , N 2  and N 3  to system B to give correction to shift α.

Title: Platen roll
Inventor: KANARI SHOHEI
IPC: B41J11/053
Filed: 1987-06-08
Abstract: PURPOSE:To largely reduce the noise of a platen roll by covering the inner periphery of a metal cylinder or any of the cylinder and the high hard rubber layer on the outer periphery of the cylinder with a lead layer. CONSTITUTION:A lead layer 5 has a damping function. For example, when the inner periphery of a metal cylinder 1 is covered with the layer 5, the layer 5 of the inner periphery is received by energy damping action due to the suitable flexibility and large surface density of the layer 5 when it is received by the vibration of the cylinder 1, thereby performing a preferable damping property. The damping effect is larger in the order of inner peripheral lead layer < outer peripheral lead layer < both inner and outer peripheral lead layers. If the weight of a platen roll is excessively large, it is inconvenient. Thus, the thickness of the lead layer is limited to its upper limit, and if the thickness is reduced, its soundproofing effect is decreased. In view of this, the range of the thickness of the lead layer is preferably approx. 0.3-1.0mm.

Filed: 1994-06-23
Abstract: PURPOSE:To obtain a good photoelectric conversion efficiency even by a short- wavelength light signal by a method wherein a depletion layer is provided on the surface of the light-receiving region of a semiconductor light-receiving device for converting a light signal into an electrical signal. CONSTITUTION:An N<-> layer 10 is formed in such a way that it is held between high-concentration P<+> and N<+> layers 11 and 12. The shorter the wavelength of a light signal becomes, the shallower the depth of the layer 10 becomes and the higher an applying voltage is made, the wider the interval between the layers 11 and 12 is made. When a prescribed potential difference is applied between the layers 11 and 12, the region of the layer 10 is turned into a depletion layer. When a semiconductor light-receiving element is designed in such a way that most of the light signal inputted in the light-receiving element is absorbed in the region of this layer 10, a high photoelectric conversion efficiency can be obtained in the layer 10 which is the depletion layer.
