Title: Macro-inspection method
Inventor: SHIGEYAMA YOSHITAKE
IPC: G06T7/00
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a macro-inspection method for accurately detecting macro- abnormality by a simple processing. SOLUTION: At first, a semiconductor wafer image is picked up, and a picked up image is inputted (a step 11). The picked up image is second-dimensional Fourier transformed, and frequency components corresponding to a pattern cell and a noise are removed from the power spectrum, and a pre-processed image is generated by the second-dimensional inverse Fourier transformation (a step 12). A multi-stage resolution image is generated from the pre-processed image, and a range filter processing and a binarization processing is performed to each image so that density non-uniformity can be extracted (a step 13).

Title: Sealing system for pump
Inventor: MACHITORI HIDEKI
IPC: F04D29/12
Filed: 1978-11-21
Abstract: PURPOSE: To increase sealing effects by forming a very small gap between the sealing portion and the peripheral surface of an rotary axis; and by forming a sealed water pot with a large diameter on the opening end side.  
     CONSTITUTION: The pressurized water in a pump chamber 2 flows into the gap of the axis sealing portion 6 from the end of a perforated passageway 5 for the axis and a distributing tube 16 for sealing water, then stays in a sealing water pot 7 after  passing through the gap, and further leaks out while widening a space between the  seal end surface 8 and a sealing ring 11. In this case, the amount of leakage of the pressurized water is exitremely small because the gap δ left in the axis sealing portion 6 is also very small. At the same time, no mechanical friction occurs in the axis sealing portion because of the leakage. In addition, when there is no pressurized water in the sealed water pot 7, the sealing 11 is attached with pressure to the seal end surface 8 by the force of deviation, so the open air can be prevented from entering the pump chamber 2 at the time of starting the pump.

Title: Infrared-ray radiation thermometer
Inventor: OUCHI KENZOU
IPC: G01J5/44
Filed: 1983-08-05
Abstract: PURPOSE:To improve sensitivity to a large extent without changing thermal response, by supporting an elastic-surface-wave element substrate by each end surface, which is in parallel with the propagating direction of the elastic surface wave, and making the propagating distance of the elastic surface wave large. CONSTITUTION:An LiNbO3 single crystal plate is used as a piezoelectric substrate 13. The propagating direction of an elastic surface wave is the direction of a Z axis. Cross finger type electrodes 11 and 12 are formed by an evapolated Al film with a thickness of about 0.15mum. The interval between the electrodes is about 6mm.. As supporting tables 15, e.g., a glass plate with a thickness of 100mum is cut into parts with a width of 1mm. and used. The substrate 13 is supported by each end surface, which is in parallel with the propagating direction of the elastic surface wave. The interval is about 2.5mm.. In this constitution, heat flowed into the substrate due to the input of infrared light flows out in the direction perpendicular to the propagating direction of the elastic surface wave regardless of the propagation distance of the elastic surface wave. Thus the propagation distance of the elastic surface wave can be made long without deteriorating thermal time constant, and the sensitivity can be improved to a large extent.

Title: Vapor deposition method
Inventor: SHIRAISHI ISAO
IPC: C23C14/56
Filed: 1978-11-24
Abstract: PURPOSE:To make material charge to the heater easy and to prevent the fall of the material from the heater, by covering the evaporation heater with vapor deposition material of coronet shape. CONSTITUTION:A coil-shaped evaporation heater 1 is covered with the evaporation material 2, and the vapor deposition is conducted by the rotation etc. of a spider with vacuum interrupted. Because the material 2 comes into contact with the heater 1 at plural parts, the material 2, which is molten during heat generation of the heater 1, wets the heater 1, so that the vapor deposition of a prescribed amount of the material is performed without fall of the pieces of the material 2 to the outside of the heater 1.

Title: Encoding and decoding device for picture signal
Inventor: ANDO ICHIRO
IPC: H04N19/70
Filed: 1989-06-07
Abstract: PURPOSE:To improve the compression rate of information quantity and to improve the picture quality by using the visual characteristic in the case of quantization of a conversion value obtained through data conversion of a picture signal. CONSTITUTION:An inputted picture signal is divided into plural blocks comprising plural adjacent picture elements for each pattern and horizontal and vertical picture elements by a block division circuit 1 to convert the signal into a picture data string for each block. The picture element data string for each block is subject to data conversion by a data conversion circuit 2 and stored in a storage circuit 3. In the case of quantizing the converted value, the quantizing characteristic of each block is decided from an average brightness of the surrounding blocks through the application of the visual characteristic whose difference sensitivity is deteriorated when a brightness difference from the surrounding parts is large, a block having a large brightness difference from the surrounding parts is quantized roughly and a block with a small brightness difference is quantized minutely. Thus, the compression rate of the information quantity is improved and the reproduced picture quality is improved in the visual sense.
