Filed: 1992-11-09
Abstract: PURPOSE:To provide a tomographic image capable of obtaining a tomographic image same as the image which would be obtained when a similar motion is made accurately even if an X-ray tube and an image receiving part may device from a geometrically relative position. CONSTITUTION:A drive mechanism 3 moves an X-ray generation source 1 and an X-ray detector 2 in the opposite direction to each other keeping a geometrically similar relationship centered on one point near a subject. A position detector 4 detects moving positions of the X-ray generation source 1 and the X-ray detector 2. A storage device 5 stores image information to be outputted from the X-ray detector 2 related to an output signal of the position detector 4. A small object 6 is the one fixed unmovable relatively with respect to the subject 9 to be placed in an X-ray transmission area, for example, a small disc made of lead. An image processing means 8 extracts a projection image of the small object 6 from the image information stored in the memory 5 to determine the position thereof. A difference is determined by an arithmetic processing means 7 between a position as specified of the small object 6 and an actual position determined by the image processing means 8 and transmitted images of the images are corrected in position to be overlapped.

Title: Speed sensing method with optical fiber encoder
Inventor: KUBOTA MUNEAKI
IPC: G01D5/353
Filed: 1991-11-14
Abstract: PURPOSE:To obtain a revolving speed in the form of analog signal by performing a computational processing for an A-phase signal and a B-phase signal having different phases generated by the use of an optical fiber. CONSTITUTION:The speed sensing method with an optical fiber encoder consists of obtaining the revolving speed (omega) from an A-phase signal SA (t) and B-phase signal SB (t) having different phases generated by the use of an optical fiber. The revolving speed omega is expressed as omegaA=-1/NSB (t)X[SA (t)-SA (t-DELTAt)]/DELTAt and omegaB=1/NSA (t)X[SB (t)-SB (t-DELTAt)]/DELTAt, where N is resolution, DELTAt is time, DELTAt is lag, and SA(t-DELTAt) is A-phase signal in lag while SA(t-DELTAt) is B-phase signal in lag, and thereby the revolving speed omega is obtained in the form of analog signal by making omegaA effective around where the A-phase signal SA (t) nullifies and making omegaB effective around where the B-phase signal SB (t) becomes zero. Because of using two forms, omegaA and omegaB, the revolving speed omega can be obtained as analog signal by means of making effective either of the two selectively in the different areas as mentioned above.

Abstract: PURPOSE:To prevent the unit cell size of a ROM from becoming large by forming an insulating film thicker than gate electrodes between the gate electrodes in a self-matching way, and by preventing the implantation under a field oxide film in the case of ion implantation with high energy. CONSTITUTION:A gate oxide film 8, gate electrodes 2, N-type high-density impurity ion implanted layers 11 are formed in element regions. Next, insulating films 9a are formed to a thickness of about 600-800nm by a liquid-phase growth method. As the insulating films 9a do not grow on resist films 10 and are formed selectively only around the gate electrodes 2 and on a field oxide film or on a gate oxide film 8, even if the insulating films are formed thicker than the electrodes 2, they can be formed in a self-matching way with the electrodes. As N-type high-density impurity layers 6 are formed by annealing and ions are implanted into mask ROM sections 3, photoresist films 4 of a specified pattern are formed, and an N-type low-density impurity ion implanted layer 12 is formed by high-energy implantation. Next, an N-type low-density impurity layer 7 is formed by annealing.

Abstract: PURPOSE:To confirm at a glance the time required for completing transmission by operating and displaying the time required up to the transmission completion from the remainder information and the transmitting speed information based on the input and output information on picture data to perform the memory transmission. CONSTITUTION:A storage part control means 9 controls a picture data storage part 2 based on the input and output information on picture data prepared by picture data input and output control means 4 and 5 and grasps the non- transmitted picture data remainder.

Abstract: PURPOSE: To form a grating by covering the entire surface of a resin-made substrate with an electrically conductive resin layer of a specified thickness, so as to achieve a weight reduction compared with metal-made grated panels and be suitable for use in clean rooms. CONSTITUTION: The entire surface of a resin-made substrate 2 is covered with an electrically conductive resin layer having a thickness of 0.1-0.5mm. Glass-fiber reinforced polyamide resin is injected at a resin temperature of 290 deg.C to form the substrate 2 of a grating under a dwell pressure of 500kgf/cm<2> . The formed substrate 2 is then taken out of a die 1 and set in a cavity 3a formed in a die 3. The size of the cavity 3a accords with the size of the final product of a grating. The substrate 2 is supported in a floating manner by pins 4 protruding from the inner wall surface of the cavity 3a, thus ensuring a small clearance between the inner wall surface and the substrate 2, for the cover layer.

Title: Detecting method for dirt on original carrying belt
Inventor: MIZUISHI HARUJI
IPC: G03G15/08
Filed: 1986-12-18
Abstract: PURPOSE:To simply detect dirt on an original carrying belt by driving the original carrying belt under no-original state, forming the image of the carrying belt on a photosensitive body and detecting the toner image on the photosensitive body by a sensor. CONSTITUTION:When the carrying belt 2 is driven under the no-original state and copying work is executed, the face of the belt 2 contacted with an original platen 3 is irradiated by light and the image of the face of the belt 2 is formed on the photosensitive body 6. If the carrying belt 2 generates dirt, the dirt forms an electrostatic latent image on the photosensitive body as a kind of an image and its toner image is formed by development. The toner image is detected by a sensor 14, a detecting signal expressed by the voltage value of image density is computed by a control device 15 and the relation of the voltage value of a previously fixed white level to the voltage value of an allowance level indicating a range allowable as dirt is decided. Thus, dirt on the carrying belt 2 can be simply detected by using the sensor 14.

Title: Image forming device
Inventor: AOKI TOMOHIRO
IPC: B41J2/525
Filed: 1987-11-30
Abstract: PURPOSE:To prevent deterioration in dislocation detecting accuracy due to electrical disturbance and to efficiently detect dislocation by independently monitoring the detecting timing of a resist mark correspondingly to respective separate image carriers. CONSTITUTION:A correcting operation control means 13 monitors the timing of when resist mark images 11 and 12 on the image carriers 1C-1BK are detected. The images are transferred onto a carrier 4 and detected by detecting means 5 and 6. The control means 13 individually limits that a correcting means 13 corrects the projection start position of light beams on the image carriers 1C-1BK at the detection timing of said resist mark images, light beam projection angle on each image carrier and the position where optical path length is projected on the image carriers 1C-1BK. Thus, dislocation correction operation can be limited when the transfer area of the resist mark images is dislocated owing to external factors not coming from mechanical position accuracy. Only image dislocation due to mechanical position accuracy can be detected constantly and can be corrected.
