Title: Method and apparatus for collecting per- fect radon data for three-dimensional calculator type tomographic image reproducion
Inventor: UOTSUKU CHIYON TAMU
IPC: G06Q50/00
Filed: 1992-06-25
Abstract: PURPOSE: To precisely regenerate the image of a part of concern without lowering the quality by performing a scanning along the upper limit and lower limit of a support area within an object space surrounding a part of concern, partitioning an integrated surface corresponding to data, and selectively operating the collected data. CONSTITUTION: According to whether an optional integrated surface, for example, a flat surface, crosses a part of concern and either one of the upper area from an upper limit boundary and the lower area from a lower limit boundary, data are selectively ignored by the operation of partitioned data, whereby an undesirable contribution is removed. Further, according to whether the optional integrated surface, for example, the flat surface crosses the part of concern and both the upper area from the upper limit boundary and the lower area from the lower limit boundary, the data are selectively combined, whereby the contribution which is lost in other cases is recovered. In this way, the undesirable contribution is removed, and the fallen out information is recovered, whereby the radon space is precisely filled to form a prefect data assembly.

Title: Surface treatment for device component
Inventor: NAKANO KOJI
IPC: B23H5/08
Filed: 1989-07-05
Abstract: PURPOSE:To obtain an excellent metallic mirror having high smoothness by forming a passivated film on a surface by electropolishing a member, grain- abrading and removing only the passivated film in the protruding portion of a member surface with an abrasive, and re-eluting electrolytic metal to a part where the passivated film is removed. CONSTITUTION:Although many fine holes or irregularities exist on the surface of a constitution member 1 the surface of which is not treated, a passivation film is formed on the surface of the constitution member 1 by metal elution action due to electrolysis with a polyshing machine 2. Concurrently only a passivated film, formed on the protruding portion of the surface of the constitution member 1 by the mechanical abrasion action with an abrasive 4, is eliminated by grain abrasion, and an excellent metallic mirror, having high smoothness and no fine hole or irregularity, is formed on the surface body of the constitution member 1 by reapplying metal elution action due to electrolysis to a part where the passivation film is removed. Thus, the spill of impurities such as metal powder and oil, etc., is eliminated in treating liquid, and high quality treating liquid can be constantly and stably obtained.

Title: Dozing driving warning device
Inventor: YAMAMOTO KEIICHI
IPC: B60W30/00
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To precisely detect a doze of a driver by excluding meandering for avoiding an obstacle, and arithmetically operating an awakening degree by using only a meandering quantity related to the doze when judging a change in a continuous awakening state of the driver on the basis of a monotonous degree, a steering state quantity and the meandering quantity. SOLUTION: A fuzzy inferring part D as an awakening degree inferring means operates after initial operation passes. An awakening degree of a driver is estimated on the basis of a monotonous degree from a travel operation state detecting means A, a steering quantity from a steering quantity calculating means B and a membership function corresponding to a meandering quantity from a meandering detecting means C. In this case, taking-in of meandering data for avoiding an obstacle in a travel traffic lane besides meandering at traffic lane changing time is stopped, relatively small meandering can be excluded, and only meandering related to a doze is selected to arithmetically operate an awakening degree. Thus, a dozing degree of the driver can be more precisely detected, and since a warning is given according to this doze, travel safety can be improved further.

Title: Solenoid fuel injection valve
Inventor: SEKINE ATSUSHI
IPC: F16K31/06
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To improve the life of an electromagnetic coil against breakage and response of a moving valve by fitting an insulation member between the proximity part of the magnetic pole of an iron core for attracting the moving valve which is moved by energizing and a case which is a magnetic passage of magnetic flux generated by energizing. SOLUTION: In this solenoid fuel injection valve 1, when driving current is passed through a coil assembly 5, a magnetic field is generated, so that magnetic flux passes through an iron core 2, a case 3, and a valve assembly 7 to move the valve assembly 7 onto an end surface which is the magnetic pole of the iron core 2. Fuel is filtered by a filter 15, passes through the insides of the iron core 2 and a pipe 10, and is injected to the inside of an internal combustion engine via the valve assembly 7. If a driving signal is OFF, the valve assembly 7 is pressed against a nozzle 6 by the reaction of a spring 9 to seal fuel. The eddy current generated when the coil assembly 5 is energized is shut down by an insulation member 4 fitted by the magnetic pole proximity of the iron core 2 and the case 3, and the insulation member 4 can prevent fuel from contacting with the coil assembly 5.

IPC: B01D29/11
Filed: 1982-09-24
Abstract: PURPOSE:To maintain the filtering capability of a screen constantly in a good condition, and to lower a running cost, and further to obtain a strainer of simple construction, by disposing a scraping member elastically in contact with a cylindrical screen rotatably in both the normal and reverse directions. CONSTITUTION:Foreign matters C are easily removed from small holes 11 because a scraping member 20 made of a brush elastically in contact with a cylindrical screen 9 turns in the normal and reverse directions with the rotation of a motor 16 in both directions, while the member 20 is pressed to the surface of the screen 9. Further, because a strainer is so constructed that the large inertial screen 9 is disposed to be in a fixed state and the small inertial member 20 is made to turn, a power required for scraping operation is saved as well as the strength required for construction parts such as bearing parts is made small, and then the construction is simplified.

Abstract: PROBLEM TO BE SOLVED: To obtain a method for evaluating the curvature of a magnetic tape, in which defects of a cassette tape is surely discriminated and the magnetic tape contained in a cassette is evaluated without disconnecting the tape. SOLUTION: In the method for evaluating the curvature of a magnetic tape, a standard camcorder 10 employing a small diameter drum surely records a test information signal on a magnetic tape in a cassette, a standard stationary VTR 30 of a large diameter drum adopting the same magnetic recording system reproduces a recorded test information signal to confirm whether or not noise is produced in the reproduced information signal, and when no noise exists, the magnetic tape is a non-defective magnetic tape with a small curve or no curve. When noise is produced, the magnetic tape is discriminated to be a defective magnetic tape with a comparatively large curve, and the quality of the cassette tape is selected.

Abstract: PURPOSE:To provide a normal result of majority decision even when the system of the voltage drop exists by inputting the clock signals of two other systems together with the output of a voltage monitoring circuit to monitor the output voltage into the majority decision circuit through the AND circuit to provide the logical product with the output. CONSTITUTION:When the voltage of the clock signal of the second system a2 among other systems becomes lower than the specified value, it is detected by a voltage monitoring circuit 4a of the first circuit part a1, and no signal is outputted to a clock synchronizing circuit 5a from that circuit, and the output to either of the input terminal of the AND circuit 10a is stopped. The AND circuit 10a stops the output of the clock signal from the second system a2 to a majority decision circuit 3 by this stop, and generates the specified clock signal and transmits it to a frequency multiplying circuit 8 and a frequency dividing circuit 2 based on the clock signals between the normal system a1 and the third system a3. Thus, the majority decision circuit 3 receives only the normal system to execute the majority decision to generate the clock signal, and the correction is correctly executed even when the system of the voltage drop appears.
