Title: Image line thinning device
Inventor: KABURAYAMA YUKIKAZU
IPC: G06T5/30
Filed: 1990-01-30
Abstract: PURPOSE:To secure the continuation of a line at a dividing boundary by storing an image to be processed in an image memory after dividing the image and then integrating these divided images after thinning the lines for each divided image. CONSTITUTION:An image memory 7 stores the image data outputted from an image dividing means 1 as the data including the information which shows whether a relevant picture element is tracked or not for each picture element and the information showing the relevant picture element is scheduled to be deleted or not. When the image lines are thinned, an image tracking part 3 decided whether the contour black picture element under tracking is deleted or not and sets a deletion schedule flag to the picture element to be deleted in a tracking mode. Even if a tracked black picture element to be deleted is included in a window used for tracking and deletion of the contour black picture element, this black picture element is confirmed in the window. Then a picture element deleting means 4 deletes the scheduled picture element after all contour black picture elements are tracked. Thus the coincidence is always secured between the line thinning results of an image at a margin part of each divided image. Then the line continuation is secured at a dividing boundary.

Title: Manufacture of semiconductor device
Inventor: MARUO YUTAKA
IPC: H01L29/792
Filed: 1992-02-05
Abstract: PURPOSE:To reduce a failure, which is caused by rewriting of data, by a method wherein regions to be formed under the ends of a floating gate are formed of a high-concentration impurity diffused layer and an oxide film under the ends of the floating gate is made thick. CONSTITUTION:A resist 114 is peeled and thereafter, when a dry oxidation is performed on tunnel regions 110 and 111 (f), the film thickness of a silicon dioxide film 113a to be used as a tunnel oxide film of the end parts of a floating gate can be made thicker than that of a silicon dioxide film 113 to be used as a tunnel oxide film of the central part of the floating gate because the impurity concentration in a semiconductor substrate is high at the end parts of the floating gate. Accordingly, an electric field due to a voltage, which is applied between the tunnel regions and floating gate at the time of writing and erasing data, is small at the end parts of the floating gate on the tunnel regions compared to that in the central part of the floating gate on the tunnel regions. As a result, a stress, which is applied to the oxide film under the ends of the floating gate, is reduced.

Title: Grain water detection system for grain drying machine
Inventor: MORI TAIICHI
IPC: G01N27/04
Filed: 1986-01-31
Abstract: PURPOSE:To dry grains stably at any time by providing an interval controller which shorten the operation time interval of a water sensor when a drying speed based upon the water detected value of the water sensor exceeds a set drying speed range. CONSTITUTION:Grains put in a drying machine are circulated downward in a drying chamber 2 repeatedly and dried by being exposed to a hot blast produced by a burner 1, and the water value of the grain in process of the circulation drying is detected by a water sensor 3 specific times to calculate the moving average value of the detected water values, and this calculated value is used as a detected water value to calculate the drying speed of the grains from the detected water value. When the calculated drying speed of the grains based upon the water value detection of the sensor 3 exceeds the set drying speed range, the temperature of the to blast produced by the burner 1 is controlled to lower temperature and while the grains are dried, the calculation time interval of the calculated drying speed based upon the water value of the sensor 3 is shortened, thereby drying the grains while calculating the drying speed of the grains. Thus, the grains are dried stably at any time.

Title: Solid detector for computed tomography
Inventor: TONAMI HIROMICHI
IPC: G01T1/20
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a solid detector for CT in which a strong artifact does not appear in the center part even if the focus point of X-ray tube moves in the slice direction. SOLUTION: The X-ray beam in the X-ray incidence direction 5 from the initial focus position passes through a low height collimator 13 in the center part, goes in a detector 2 which takes in the signal at the opening of X-ray incidence width 7 from the focus position. On the other hand, the X-ray beam in the X-ray incidence direction 6 after moving the focus is limited by the upper edge of right collimator and the lower edge of left collimator of low height collimator 13, which takes in the signal at the opening of X-ray incidence width 8 after moving the focus. A collimator shield plate center is designed to be gradually higher from the center to the periphery and so the difference in the opening area of the two 7 and 8 geometrically becomes very small.  Therefore, detector output variation due to the focus movement becomes very small and no strong artifact generated in the center part (corresponding image of ϕ30-ϕ50) is seen.

CONSTITUTION:An ink liquid is pumped from an ink tank 1 by a pump 2 and injected under pressure into the channel of a nozzle 52 of a particle-forming mechanism 5 through a three-way selector valve 3 and a filter 4. Then, ink particles 11 are ejected from a nozzle port 51 toward recording paper 8 by the vibration of a piezoelectric element 53, and the particles 11 thus ejected are charged with electricity by a charging electrode 6 in accordance with printing signals. Thereafter a charged ink particle 12 is deflected by a deflection electrode 7 and collected by a gutter 9, while an ink particle 13 charged with no electricity is made to go straight ahead. Simultaneously, another piezoelectric element 54 is driven to change the form of the nozzle port 51 on a plane perpendicular to the plane of charging deflection in accordance with a frequency. Thereby the ink particles are made to fly along a sine wave within the range of an angle theta and stick onto the recording paper 8 for printing.
