Title: Partial pseudo halftone picture reader
Inventor: KUMAGAI TATSUYA
IPC: H04N1/40
Filed: 1986-05-21
Abstract: PURPOSE:To read an original picture in one time and a short time by setting a binarization processing area and a dither processing area in an original picture area beforehand, and executing respective processings for the two areas. CONSTITUTION:A binary-dither decision part 13 decides whether the area to be read is the binarization processing area 10b or the dither processing area 10a based on an already stored data, the number of the enable signals En counted by a Y-direction counter 12y, and the number of the clock signals CL counted by an X-direction counter 12x, and outputs the result of the decision to a P-ROM 14. The P-ROM 14 outputs to a comparator circuit 15 a signal S0-S3 according to a matrix under the command P of the binary-dither decesion part 13. The comparator circuit 15 compares the output P0-P3 of an A/D converter 11 and that S0-S3 of the P-ROM 14, and the binarization processing and the dither processing respectively corresponding to the binary picture area 10b and the halftone picture area 10a are executed. As a result, a partial halftone picture can be read in one time and a short time.

IPC: B09B3/00
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To produce an incineration ash recycled material, free from dioxin detected by a dioxin analysis and capable of preventing the elution of heavy metals due to the hydration reaction in an accelerating test under a strongly acidic environment by a method free from environmental pollution. SOLUTION: In this method for detoxifying and recycling incineration ash, raw ash is treated in a space of a low oxygen state insulated from the outside air at a fixed temperature for a fixed time, and the generated gas is heated in the presence of a catalyst to be detoxified. The heating is carried out in the presence of a rare earth metal catalyst made from an incineration ash treated material. The method is composed of a reducing reaction treatment process and a stabilizing reaction treatment process. In the reducing reaction treatment process, the waste gas is detoxified. Before the stabilizing reaction treatment process and/or before the reducing reaction treatment process, the incineration ash to be treated is pulverized into 100-150 mesh fine particulate. The reducing reaction treatment process is carried out by keeping the incineration ash at 400-600 deg.C for 20-40 min.  The incineration ash treatment device is composed of a reducing reaction treatment device, a stabilizing reaction treatment device, and an exhaust gas treatment device.

Title: Pit forming method for optical master disk and master disk exposure machine
Inventor: MIZUTA OSAMU
IPC: G11B7/26
Filed: 1992-04-09
Abstract: PURPOSE:To obtain stable signal amplitude with same groove width in spite of pit length by exposing the pulse of a short pit repeatedly when a long pit is exposed. CONSTITUTION:A laser beam from a laser beam source is stopped by an objective lens after applying light quantity modulation and pulse modulation, and exposure is applied to a resist plate rotating and travelling. When the long pit of such as 10T is exposed, the long pit with same groove width W3=W4 can be formed by exposing the pulse of the pit of 1T with groove width W4 repeatedly. The interval of the pulse at that time is set less than 1/4T. By employing such exposure system, it is hard to generate the influence of heat due to the continuous irradiation of the laser beam, and the exposure with same width as that of the pit of 1T can be performed. Also, the depth of the groove can be set at the same depth as 1sm=1vfo.

Likewise, the selected limit switch monitors the operation of a lever Y6 associated with a Y movable carriage 4 to the direction of Y as well. When the limit switch senses the lever Y, the controller 9 controls the drive of a motor Y2 to prohibit the Y movable carriage 3 from moving to the direction of Y that the Y movable carriage 4 is now moving.
