Title: Radiation detector
Inventor: MAIO KENJI
IPC: G01T1/20
Filed: 1986-09-10
Abstract: PURPOSE:To reduce the incidence of characteristic X rays on a detector and to improve to picture quality of a CT image by extending a separator plate between detecting elements to the front of a detector. CONSTITUTION:The separator plate 4 is protruded upward from the top surface of a fluorescent body 1 and a separator support material 3 is provided on the top surface of the fluorescent body 1. Characteristic X rays from above pass through the support material 3 and are incident on the fluorescent body 1 and converted into light. The light is converted by a photodiode 2 into a current, which is outputted as a signal current. Characteristic X rays which are incident slantingly strike on the separator plate 4 and are absorbed by it. Consequently, the incidence of characteristic X rays on the detector is reduced and the picture quality of the CT image is improved.

Filed: 1984-10-11
Abstract: PURPOSE:To measure the curvature of a tube on on-line basis from the difference between the maximum and minimum value of the isolation distance between the outer peripheral surface of the tube and a reference position by detecting the isolation distance while rotating the tube in a circumferential direction. CONSTITUTION:The center of the pipe P between places where it is supported by supporting devices S is invariably on center lines of the devices, so when the pipe P which has curvature is rotated by rotating rolls R in a circumferential direction, the center of the pipe P runs on the axial line of a distance detector when the pipe P comes closest to and farthest from the distance detector D. Namely, the detector D is arranged right above the center point of the beam part of the pipe P or at >=2 optional positions in the lengthwise direction of the beam part to detect the distance to the upper end of the outer peripheral surface and obtain the maximum and minimum values, calculating the curvature of the pipe P. Thus, the curvature is measured on on-line basis in a manufacture line of a seam welded pipe, etc.

Title: Color electrophotographic method
Inventor: TAKASHIMA YUJI
IPC: G03G13/01
Filed: 1985-09-26
Abstract: PURPOSE:To prevent a developing device from contamination due to a different kind of toner by suppressing the reverse dispersion of torer from a photosensi tive body. CONSTITUTION:It is supposed that there is no toner on a developing sleeve 25 and a positive DC voltage with almost the same potential as that of the latent image of a non-image part on the photosensitive body 23 is applied to the sleeve 25. Since the potential difference between the developing sleeve 25 and the photosensitive body 23 is almost zero in an area C, toner 24 on the photosensitive body 23 in the area C is not dispersed. In an area D, the direction of an electric field between the developing sleeve 25 and the photosensitive body 23 is turned to a direction for suppressing the dispersion of the toner 24 existing in the area D, so that the reverse dispersion of toner from the photo sensitive body 23 to the developing sleeve 25 will not be generated. Consequently, the reverse dispersing phenomenon of toner from the photosensitive body having a toner image is not generated and the developing device can be prevented from contamination due to a different kind of toner.

Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a circuit for reducing a DC offset that does not need a sample string or a preamble with a prescribed value without affecting a band width of a transmission medium. SOLUTION: In order to reduce DC offset of burst signals B1, B2 of a digital signal S1, an averaging device AV averages some samples of one bust in digital bursts B1 not having a prescribed value in order to obtain a correction value CV. In the meantime, the samples of the digital burst signals B1 are tentatively stored in a memory MEM1. Then the DC offset correction value DV calculated by the averaging device AV is subtracted from samples of the digital burst signals B1, B2. Thus, the dynamic range of the samples is greatly narrowed.

Abstract: PROBLEM TO BE SOLVED: To provide an ejector control device for an injection molding machine capable of automatically setting a value judging the abnormal load applied to an ejector shaft without requiring an operator. SOLUTION: A disturbance estimating observer for estimating the load applied to a servo motor for driving an ejector shaft is provided. In the operation of an ejector, the disturbance load torque estimated by the observer is sampled (0-j) at every predetermined cycle to circulate the data DA(0, 0)-DA(i, j) of ejector processes of (i+1) times to a table TA to store them therein. The average values DB(0)-DB(j) of the estimated disturbance load torque are successively calculated from the table TA to be stored in a table TB. The upper limit values DC(0)-DC(j) and lower limit values DD(0)-DD(j) within a tolerance range are calculated from the average values to be stored in tables TC, TD. When the calculated estimated disturbance load torque exceeds the tolerance value, an abnormal load signal is outputted.  An abnormal load judging tolerance range is automatically set and accurate ejector abnormal load can be detected.
