Title: Printing test method of dot printer
Inventor: SAITO KATSUHIRO
IPC: B41J29/46
Filed: 1991-04-09
Abstract: PURPOSE:To maintain printing quality of a dot printer by a method wherein a graphic synthesized of a diagonal line of a regular square is in a reciprocative manner printed as a test pattern, and a dot dropout test and a reciprocating printing shear test are simultaneously carried out. CONSTITUTION:In the case of dot omission at an upper edge and a lower edge in test patterns 1 to 3, a complete square is not formed and therefore, dot dropout is obvious. Further, in the case where an intermediate dot between a first dot and a second dot is dropped out, since dropouts are generated at four positions on left and right vertical lines and diagonal lines like the case (3), the dot dropout can be easily discovered. Further, if only a slight displacement DELTAd exists between the vertical lines of the regular squares at respective upper and lower stages, since the vertical lines of the regular squares at respective upper and lower stage are not only on a common perpendicular line, but also intersecting points of the diagonal lines of respective test patterns shift with each other, presence of shear in reciprocative printing can be easily judged.

Title: Data converter
Inventor: MURAI KIYOAKI
IPC: H04N1/405
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To realize error diffusion processing per one pixel through memory accesses with less number of times than the number of pixels include in a range of the error diffusion processing. SOLUTION: The data converter is provided with buffers MB, SB each incorporating a register accesible at high speed and a weighted density error erws is obtained by deciding an on/off dot of a target pixel P, calculating a gray level error erw and shifting the result by a shift register SR. The gray level error erws is outputted to the buffers MB, SB, where the gray level error erws is accumulated to the gray level error having so far been obtained, and an output of each buffer is being sifted to a next stage every time the target pixel is moved. As a result, the number of access times to an SRAM 16 that is a low speed memory is decreased twice per one pixel so as to quicken the error diffusion processing.

Abstract: PURPOSE:To manufacture a contact material as flaky chips in a hardly segregated state by dropping a flow of a molten alloy for contacts on a continuously moving metallic strip and by solidifying the dropped alloy by rapid cooling. CONSTITUTION:An alloy for contacts is put in a crucible 2 and melted by heating with an electric furnace or a high frequency heating furnace 3.

IPC: C01B31/08
Filed: 1991-03-15
Abstract: PURPOSE:To obtain a nice-looking granular activated carbon with its adsorptivity hardly deteriorated and without soiling the fingertip when the hand touches it by adding PE or PP powder to granular activated carbon and then irradiating the activated carbon with FIR. CONSTITUTION:A PE or PP powder having 1-50mum particle diameter is added to granular activated carbon and mixed. In this case, the powder is attracted on the activated carbon surface in uniform thickness by utilizing the static electricity generated between the activated carbon surface and the plastic powder surface. The activated carbon is then irradiated with FIR of 10-20mum wavelength to melt the plastic surface to form a coat, and the desired granular activated carbon coated with the transparent plastic film is obtained. Since the coat is formed on the surface in uniform thickness and the PE or PP film is highly diffusible to gases, the adsorptivity of the activated carbon is hardly decreased by the coat.

Filed: 1988-04-26
Abstract: PURPOSE:To prevent momentary interruption due to deterioration in quality of a different polarized wave by switching both radio lines to a standby radio line depending on the degree of deterioration if one quality of the two radio lines is deteriorated. CONSTITUTION:A frame synchronizing device 51V outputs a deterioration detection signal S1 if the quality of any of radio lines 1V to kV, 1H to kH, e.g., an active radio line 1V, is deteriorated. A line switch controller controls a transmission line switch 10 when the deterioration detection signal S1 is received to output a composite data signal outputted by transmitters 21V, 21H to transmitters 20V, 20H. Succeedingly, the line controller controls a receiving end line switch 60 to output the data signal via a standby radio line PV, PH to the receiving end in place of the data signal via the line 1V and 1H. Through the line switching, the line interruption due to the propagation of the quality deterioration of the line 1V is relieved and line interruption due to the deteriorated quality of the line 1H by the cross polarized wave interference due to the deteriorated quality of the line 1V is prevented in advance.
