Title: Color picture compression method
Inventor: WATANABE MASANORI
IPC: G06T11/60
Filed: 1994-10-18
Abstract: PURPOSE: To naturally convert a color picture to a pseudo color display and to effectively use existing equipment. CONSTITUTION: In an original color picture inputted from a color picture input part 1, the RGB values of the color picture are mapped in a color space by a color space division part 6. The color space is divided into a prescribed number of plural partial areas so that the accumulation of the evaluation values of a distance between the representative color of the partial area to which the color value of a picture element belongs and the color value of the picture element becomes small on all the picture elements and the representative colors of the respective partial areas are decided. A color map generation part 3 generates a correspondence table between the serial numbers of the respective partial areas and the representative colors as a color map by using the result.  A following color picture conversion part 4 adds the serial numbers to the partial areas in the divided color space and replaces the respective picture elemests of the input picture with the numbers of the partial areas to which the picture elements belong. Thus, a compressed/encoded picture (compressed picture) is obtained.

Title: Ejector nozzle for slag suction removal
Inventor: TAKEISHI YOSHIAKI
IPC: F27D3/15
Filed: 1987-10-06
Abstract: PURPOSE: To prevent fusion or adhesion of stag by forming a flared slag suction port, providing an annular slit nozzle at a specified ejection angle in the pipe wall directly above the suction port and the linear pipe section of specified length sequentially with a curved delivery pipe having a specified radius of curvature. CONSTITUTION: An annular slit nozzle 14 is made between a flared pipe 11-1 and a linear pipe section 11-2 such that the driving fluid ejection angle 9 will be 45 deg. or less with respect to the suction pipe wall. The linear pipe section 11-2 above the slit nozzle 14 has a length L equal to or longer than two times of the inside diameter D of the suction pipe. Radius of curvature of the linear pipe section 11-2 is set equal to or longer than four times of the inside diameter D of the suction pipe. Since the driving fluid is ejected at an angle θ of 45 deg. or less with respect to the suction pipe wall, inner surface of the suction pipe 11 and a curved delivery pipe 12 is cooled through temperature drop caused by angular expansion of driving jet.  Furthermore, slag flows smoothly through the suction pipe 11 and the curved delivery pipe 12 because of the flared suction port and the curved pipe having a large radius of curvature.

Title: Magnetohydro turbo apparatus
Inventor: UIRIAMU FURANSHISU HANAN ZA SA
IPC: H02K44/04
Filed: 1990-09-25
Abstract: PURPOSE: To increase an output voltage by forming a proper electrode surface at the outer-periphery and inner-periphery parts of a device and performing liquid contact. CONSTITUTION: A current J in a radial direction, flowing in a fluid 48, generates acceleration in a peripheral direction at the flow of the fluid 48 in a left annular channel 34, in the presence of a magnetic field B in a side direction. When the fluid 48 flows from a point A to a point B, a large amount of pressure is generated in the flow of the fluid 48. After that, the fluid 48 passes through an outside turbine blade 46 and moves from the point B to a point C, thus causing a change in liquid momentum to generate a torque in a disk 32. Although the fluid 48 at the point C moves relatively slowly, pressure is large. By guiding the flow of the fluid 48 to a right annular channel 36, the fluid 48 generates a controlled turn and hence a high-voltage energy is speedily and effectively converted at a point D.

Title: Semiconductor element manufacturing equipment
Inventor: KURIHARA HIDEO
IPC: H01J37/317
Filed: 1990-09-20
Abstract: PURPOSE:To alleviate a field which is generated on a substrate for a semiconductor element for preventing an insulated film from being damaged by the field by controlling the potential by a potential control device so that the front surface and rear surface of the semiconductor which is brought into contact with a conductor may be at the same potential. CONSTITUTION:When the ion beam is cast on a wafer 1 which is secured by a clamper 3 on a wafer support rest 2 which is placed on a turn table 5, the potential at the front surface of the wafer 1 rises in a moment and there appears a difference in potential between the front surface and rear surface of the wafer 1 because the support rest 2 is connected directly to the earth potential through the turn table. However, since the support rest 2 is connected to the earth potential through a resistance 4, the rear surface of the wafer 1 immediately gets electrified like the front surface and thus a difference in potential between the front and rear surfaces of the wafer 1 is reduced. Consequently, a field which is generated on the wafer 1 can be alleviated and an insulated film is prevented from being damaged.

Title: Temperature measuring apparatus for semiconductor during the heating of lamp
Inventor: HIURA KAZUO
IPC: C23C14/54
Filed: 1985-11-13
Abstract: PURPOSE:To always monitor the wafer temperature stably, by providing a temperature measuring window made of material transmitting a wavelength of 5mum-10mum at an apparatus for heating a wafer with a lamp through a quartz window plate. CONSTITUTION:A semiconductor wafer 1 held on a wafer holder 2 with a vacuum chamber is heated by a radiation light from a lamp 6 put on the atmospheric side through a quartz window 5. An infrared ray 13 emitted from the wafer 1 is extracted through a window 14 made of CaF2 which transmits the wavelength of 5mum-10mum efficiently and the temperature thereof is measured with a radiation thermometer 9A having a filter that transmits light alone with the wavelength exceeding 5mum. As quartz absorbs the wavelength above 5mum, reflection on the wafer 1 of light from the lamp 6 will not cause erroneous measurement with the thermometer 9a. The cooling of the quartz window 5 by a blower 15 can prevent possible error by reflecting the radiation light of the window 5 itself by the wafer 1.

Abstract: PURPOSE:To easily detect the occurrence of a leak by installing a vibration frequency measuring sensor on the heat insulating box of primary system piping, and measuring and comparing a vibration frequency generated by the heat insulating box when the leak is caused with a vibration frequency at the time of normal operation. CONSTITUTION:If the leak opening 5 is caused in an entrance tube 2 in the heat insulating box 1, a cooling material 6 spouted out of the leak opening 5 strikes on the heat insulating box 1 and then the heat insulating box vibrates differently from vibrations in the normal operation, so the frequency measuring sensor 7 measures the vibration frequency at this time.

The attenuation of the vibrations in metal is small and the vibration frequency measuring sensor 7 fitted to the heat insulating box 1 detects leaks inside and outside of the heat insulating box 1.
