Title: Method and device for drawing polygon
Inventor: ICHIKAWA AKIRA
IPC: B41J2/485
Filed: 1991-01-09
Abstract: PURPOSE:To improve entire processing speed by decreasing the number of times for sorting without detecting the intersection of paths. CONSTITUTION:When drawing an arbitrary graphic applied by contour information while painting the inside out with scan lines, the line list of a path crossing the scan line for the first time is prepared when the path crosses the scan line, a sort line list is prepared by sorting this line list in an ascending order concerning the position of the intersection with the scan line, and paths to be drawing blocks are calculated corresponding to a designated paint-out rule based on this sort line list. Then, a fill list to manage those paths as pairs is prepared and while this sort line list is not updated, the drawing blocks are successively calculated based on this fill list. When no path crosses the scan line or it is judged the paths cross each other, the sort line list and the fill list are updated and these steps are further repeated.

Title: Moving weight measuring system
Inventor: OKUYAMA SHIGEAKI
IPC: G01G17/08
Filed: 1993-01-08
Abstract: PURPOSE:To allow individual weighing of two objects even when the two objects pass continuously over a weighing mat. CONSTITUTION:If a data section setting means 11b sets two different data sections before an exit detecting means 9 detects an object to be weighed after an entrance detecting means 8 detected the object, a valid data section decision means 11c decides that the first data section is an independent valid data section and the latter data section is an overlapped valid data section. An operating means 11d calculates the rest weight of an object having higher priority from a time series data in the independent valid data section while furthermore calculates an overlapped rest weight from a time series data in the overlapped valid data section. The rest weight of the object having higher priority is then substracted from the overlapped rest weight thus calculating the rest weight of an object having next priority.

Abstract: PURPOSE:To vary minimum transmission time optionally while securing the minimum transmission time with simple constitution by counting the number of every block of transmitted data, by comparing it with given data, and by adding an insignificant bit. CONSTITUTION:Image information from a scanner 1 is coded, block by block, by a coder 4 and a synchronizing code is added to generate an output; when the synchronizing code of each block is generated, a bit-number counter 7 is reset, and every time the coding processing of the image information ends, access to a comparator 8 is attained. When a signal from the comparator 8 is not supplied to a switch circuit 6, the output of the coder 4 is applied as transmitted data to the counter 7 and when the signal is supplied, a signal from an insignificant- bit generator 5 is applied to the counter 7. Then, data from a latch circuit 9 is compared by the comparator 8 with the count value of the counter 7 for every block to vary minimum transmission time optionally, thereby sending an image signal from a modem 3 to a circuit.

IPC: H01L21/3205
Filed: 1986-01-10
Abstract: PURPOSE:To prevent the generation of Al projections in an electrode wiring, by sputtering Al/Si, forming an Al/Si film, thereafter depositing pure Al on the surface of said film by sputtering, forming a pure Al film 19, performing anodic oxidation of the surface, forming an AO film, and thereafter performing the patterning of the electrode wiring. CONSTITUTION:On a semiconductor substrate 10, Al/Si is sputtered and grown to a thickness of 7,000Angstrom . Thus an Al/Si film 11 is formed. Then, pure Al is grown to a thickness of 1,000Angstrom  by sputtering, and a an Al film 18 is formed. Then, the Al film 18 is oxidized by anodic oxidation. A fine AO film 14 is formed as an Al-projection preventing film. Since Si is not included in the Al film 18, the AO film 14 having a uniform thickness is formed on the surface by the anodic oxidation. Discontinuous parts or thin parts are not formed in the AO film 14. Thus the generation of the Al projections is suppressed. Si 13 is included in a part, where the pure Al is not oxidized. A double-layer structure comprising the Al/Si film 11 and the AO film thereon is formed on the semiconductor substrate as a whole. Short circuits between an emitter and a base are prevented as in conventional devices.

Filed: 1984-01-09
Abstract: PURPOSE:To prevent the failure due to the deterioration of the titled diode (APD) due to local punch-through by inhibiting the reaction between Al and Ge by mixing a slight amount of Ge element into an Al electrode. CONSTITUTION:Ge elements 16 are mixed into the Al electrode 3; thereby, the penetration of the Ge of Ge crystals in a guard ring 8, the substrate, into the Al electrode 3 and the generation of the Al into the Ge crystals are inhibited or reduced to cancel. The larger is the Ge amount mixing into the Al, the larger is the inhibiting effect; however, the rate of mix-in of Ge into Al is optimum at 2-5wt%. In this range, bonding failure or the increase in specific resistance of the Al electrode becomes out of problem, the local punch-through of the APD can be inhibited by inhibition of the reaction between Al and Ge.
