Title: Image processor and image processing method
Inventor: UENO KUNIKAZU
IPC: H04N1/409
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To apply a smoothing enlargement to characters with background and line drawing in a color multi-valued image by preventing occurrence of void without increasing number of jaggy detection patterns. SOLUTION: A binary processing circuit 64 applies binary processing to a character and line drawing in a color multi-valued image based on a result of detection by a Tag discrimination circuit 63. A smoothing enlargement circuit 65 applies smoothing enlargement processing to data of the character and line drawing that are binary-processed by using a jaggy detection pattern and a magnified output pattern stored in a ROM 68. A background calculation circuit 66 calculates a pixel value (non-background value) of a pixel denoting the character and line drawing and a pixel value (background value) of other pixels. A binary multi-value conversion circuit 67 converts the binary smoothing enlargement image data obtained by the smoothing enlargement circuit 65 into multi- value image data based on the non-background value (multi-valued data) and the background value (multi-valued data).

Title: Method for scanning tablet
Inventor: HASHIMOTO SOJI
IPC: G06F3/044
Filed: 1993-10-28
Abstract: PURPOSE:To quickly generate coordinates by predicting a succeeding scanning starting position for the abutting position of a coordinate indicator upon a tablet from basic data for calculated coordinates and ending the scanning when data necessary for coordinate calculation can be inputted. CONSTITUTION:In an initial state, electrode lines in the whole area of the tablet 1 are scanned by analog switches 2, 3 for every several electrode lines. A signal detected by a selected electrode line is converted into a digital signal by an A/D converter 6 and the digital signal is impressed to a control circuit 7. The circuit 7 compares the digital signal with a set threshold level, and when the digital signal is higher, decides that a stylus pen 4 exists in the vicinity of the electrode line and continuously scans electrode lines near the electrode line concerned to predict the existing position of the pen 4. The circuit 7 specifies an electrode number for starting scanning, and when upper three data out of inputted signals are matched and the succeding data level is lower than the threshold level, aborts the scanning and calculates coordinates.

Abstract: PURPOSE:To enhance the electric resistance of a container by providing a reciprocating part on the wall of the vacuum container, and alongating the path of one round in the direction of a torus. CONSTITUTION:A vacuum container 2 for torus-type nuclear fusion apparatus for confirming plasma 1 in the inside is constituted of an inner wall 2a and an outer wall 2b based on the reasons for providing a cooling flow path in the inside and so on. The inner and outer walls 2a and 2b are bent along the direction of the torus. A returning route is inserted in series. The path of one round in the direction of the torus is made longer than the case wherein the container is formed of the container wall, which is in parallel with the central line of the plasma. The supporting and the fixing of the inner and outer walls 2a and 2b are realized by providing ribs 9 for supporting and fixing the inner and outer walls at the suitable positions in the torus direction and by connecting the inner and outer walls 2a and 2b by metallurgical bonding. The deformation between the inner and outer walls 2a and 2b between the ribs 9 is prevented by FRP and a ceramic insulator 7 for preventing the deformation of the inner and outer walls. The insulator 7 is fixed to the inner and outer walls with an insulator fixing metal fitting 8. The effects of an irregular magnetic field and the like acting on the container is made less by enhancing the electric resistance of the one round of the vacuum container.

Title: Power supply switch device
Inventor: YOSHINAGA AKIISA
IPC: H01H9/56
Filed: 1987-11-21
Abstract: PURPOSE:To suppress noise which occurs during current interruption by detecting a minimum value of a load current to produce a current interruption timing. CONSTITUTION:A wave form of a load current is drawn from a transformer 2A at a no-load detection sensor part 2 and its wave form is shaped by a slicer 2B. Thereafter a no-load point timing is extracted and its output (e) is sent to a timing extraction circuit part 3 to produce an optimum current interruption timing. At the beginning of a power supply the output becomes high-level to a manual switch circuit 4 at a lapse of a constant delay time. During interruption of power, a function of a timing adjustment circuit 6 is used to delay the output by a time, which is subtraction of a relay's own delay time from one cycle of a power source period, from a no-load point timing after the manual switch part is turned off and then to make the output become low-level. The output of a timing adjustment circuit 6 is supplied to a relay drive circuit part and controlled to interrupt the relay in an electromagnetic switch part 3 during no load. Occurrence of noise is thus suppressed.
