Title: Device and method for inspecting surface defect
Inventor: HARUNA KAZUYUKI
IPC: G01N21/89
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To enhance the precision of secondary judgement of surface defects. SOLUTION: Image pickup signals from a scan camera 6 are always input to an image pickup signal storage part 73 to form two-dimensional images. A control part 74 extracts portions of the two-dimensional images corresponding to surface defects detected in primary judgement as defective images at a timing when a unit area where the surface defects in primary judgement exist passes through an image pickup position of the scan camera 6. The extracted defective images are reserved as database in a reservoir 9. A monitor 8 usually shows the results of the primary judgement but shows the defective images in respect to the specified surface defects for secondary judgement when instructions for secondary judgement are given by an operator.

Title: Vapor growth equipment
Inventor: TAKEBAYASHI MIKIO
IPC: H01L21/205
Filed: 1986-03-07
Abstract: PURPOSE:To prevent the formation of a deposit, which is the source of dust, on the inside wall of a reaction chamber as well as to increase the growth rate of a thin film by a method wherein a plurality of thin plates, with which purging gas is supplied from a gap part, are arranged inside the reaction chamber in such a manner that the inner surface of the reaction chamber is coated with the thin plates. CONSTITUTION:A reaction chamber 1 is vacuum-exhausted from an exhaust hole 2, and reaction gas and purging gas are fed from a reaction gas feeding hole 3 and a purging gas feeding hole 9 respectively. As the feeding of reaction gas into a transparent quartz 7 and the inner wall of the reaction chamber 1 is prevented by the purging gas supplied from the gap part of a plurality of transparent quartz plates 8 arranged in stepped form covering the inner wall surface of the reaction chamber 1, the deposition of a deposit on the inner wall of the reaction chamber 1 can be prevented. Also, as the supply of reaction gas to the transparent quartz plates 8 themselves is prevented by the purging gas coming out from a plurality of transparent quartz plates 8 arranged in stepped form, no deposit is formed on the transparent quartz plates 8. Moreover, as the degree of concentration of gas reaching a semiconductor wafer 4 becomes higher, the growth rate of the thin film can be increased.

Abstract: PURPOSE:To reduce the distortion of a reproduced sound by making a gas adsorbent adsorb/discharge gas sealed in an enclosure according to the change of the internal pressure of the gastight type enclosure due to the vibration of the diaphragm of a speaker unit. CONSTITUTION:In the internal part of the enclosure 2, air containing gaseous nitrogen is sealed, and simultaneously, a heater 8 coated with gas adsorbent 7 to adsorb/discharge the gaseous nitrogen is provided. Thus, in a speaker device 1, since the gas adsorbent 7 adsorbs/discharges the gaseous nitrogen according to the change of the internal pressure of the enclosure 2 due to the vibration of the diaphragm 6, elastic force acting upon the diaphragm 6 and due to the air in the enclosure 2 is moderated. Therefore, the distortion of the reproduced sound can be reduced.

Title: Safety management method on construction job site
Inventor: WADA SHOZO
IPC: E04G21/32
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To recognize danger in surrounding environment and to evacuate safely at an emergency by unifying by a color the moving objects to which workers' approach is prohibited on a construction job site where various construction machinery and construction materials are located and unifying the fixed objects with a color different from that of moving objects. SOLUTION: Various machinery and materials on the construction job site are roughly classified into moving objects and fixed objects. Next, each of moving objects is painted with all unified same color different from that unified for fixed objects. The moving objects are such as bulldozer, shovel type excavator, loader, crane, pile driving tower or the like which move on the job site and create danger situation and thus the workers are prohibited to freely approach these machines. For these machines, the color is unified with an orange-based or yellow-based color which gives a feeling of danger to the workers. Then, fixed objects such as a fence, handrail, temporary scaffolding, concrete form, timbering or the like is unified with a greenbased color. Therefore, the workers pay more attention to the safety and quickly and safely evacuate during emergency.  In this way, the safety management can be enhanced in various construction job sites.

Abstract: PURPOSE: To prevent a gasket from being affected by local thermal expansion and to improve the seal-up function of the gasket, by providing slits in the peripheral part around exhaust port so that the slits extend in parallel with the meeting surface of a cylinder head on a cylinder block.  
     CONSTITUTION: Slits 10 are provided in a part around the gathering section 9b of an exhaust port 9 so that the slits extend in parallel with the meeting surface of a cylinder head 6 on a cylinder block 5. The slits 10 are located on the production of the diameter of the gathering section 9b and extend along the total length of the gathering section. The slits 10 are opened into the gathering section and have a width corresponding to the thermal expansion difference between the part around  the gathering section 9b and another part distant from the former part. According to this constitution, deformation due to thermal expansion is absorbed in the cylinder head 6 even if the temperature of the part around the exhaust port 9, especially the part around the gathering section 9b liable to take a high temperature, becomes higher than that of another surrounding part distant from the former part. Therefore, a gasket is prevented from being affected by the deformation and the seal-up  function of the gasket is improved.
