Title: Picture tracking device
Inventor: SHINOHARA HIROSHIGE
IPC: G06T7/20
Filed: 1990-08-25
Abstract: PURPOSE:To improve detecting accuracy by a method wherein a density histogram in a background window is subtracted from a density histogram in a target window by a subtractor and the result of subtraction is added with a variable positive offset value while the density of frequency, which becomes the offset value or more, is operated as the value of target extracting density. CONSTITUTION:A subtractor 19 subtracts density histograms in background windows A-D from density histogram in a target window T and adds the result of subtraction with a variable positive offset value while the density of frequency, which becomes higher than the offset value, is operated as the value of target extracting density and is output to a target extracting unit 20 as a target density value signal. The target extracting unit 20 extracts the targets in respective pictures after a next time based on the value of target extracting density and is provided with a memory element such as a RAM or the like while the value of density, which is higher than the variable density gradation of 0-255, is used for the address of the memory element when the value of target extracting density is output from the subtractor 19. When the value of density is equal to the value of target extracting density, (1) is written as a data while a data (0) is written when the value of density is different from the value of target extracting density.

Title: Paper feeder
Inventor: MITSUYA TOSHIYUKI
IPC: G03G15/00
Filed: 1989-08-30
Abstract: PURPOSE:To suppress diagonal conveyance of paper with pressing force equalized of both separator rollers for the paper during its conveyance by providing a restricting means which is engaged with a pawl of a ratchet wheel, when necessary, to restrict turning both the separator rollers. CONSTITUTION:In the case of conveying paper by a paper feed roller 2, in a restricting means 6, a two-sheet feed (double feed) of the paper is prevented by restricting turning a pair of separator rollers 3, 4 brought into press contact with the paper, but turn restriction of the separator roller by the restricting means is performed by engaging a pawl member 64 with a pawl 51 of a ratchet wheel 5 interposed between the pair of separator rollers. Thus by restricting turning in the intermediate between both the separator rollers, reaction force to a side of the paper feed roller for the turn restriction acts on the intermediate part between both the separator rollers, and the separator rollers are prevented from tilting for the paper feed roller. Accordingly, pressing force of both the separator rollers is equalized for the paper during its conveyance, and diagonal conveyance of the paper can be suppressed.

Title: Bus wait device
Inventor: EDOWAADO EMU JIEIKOBUSU
IPC: G06F13/42
Filed: 1993-08-17
Abstract: PURPOSE: To deal with a bus waiting signal generated with slow timings without using a high-speed element or circuit constitution by allowing a retry queue to hold a last N-bus cycle to retry each cycle on a bus. CONSTITUTION: A waiting command 302 is asserted during a bus cycle TO by a bus module. In this case as the result of the asserting command, bus cycles T1 to T4 are waited. Then data words d1 to d existing during the waiting time 304 are invalid by the definition of a protocol. The data words d1 to d4 are retried on the bus by a bus driving module during bus cycles T5 to T8 and each data word d1 to d4 is valid at this step. Then this receiving bus module relinquishes or neglects data of the bus cycles T1 to T4 but uses data of the bus cycles T5 to T8.

Abstract: PROBLEM TO BE SOLVED: To protect a superconductive thin film and to improve the characteristics of an entire circuit using the superconductive thin film by forming first and second thin films which water molecules do not permeate on the surface and the side wall of the superconductive thin film which is subjected to patterning and forming an interlayer insulation film consisting of polyimide resin or SOG on the entire surface. SOLUTION: Since a first thin film 30 and a second thin film 40 are formed on a surface 20a and a side wall 20b of a superconductive thin film 20, the surface 20a and the side wall 20b of the superconductive thin film 20 can be protected from an external damage when forming a circuit using the superconductive thin film 20 or when using the circuit. Also, when forming polyimide resin or an interlayer insulation film 50 by SOG, water is generated from the interlayer insulation film 50. But, the surface 20a and the side wall 20b of the superconductive thin film 20 in a specific shape are protected by first and second thin films 30 and 40 consisting of a material for essentially blocking the permeation of water molecule, thus preventing the surface 20a and the side wall 20b of the superconductive thin film 20 from being damaged due to water and hence deteriorating.
