Title: High voltage power feeding method
Inventor: TAJIMA NAOKI
IPC: H01R4/48
Filed: 1992-07-22
Abstract: PURPOSE:To secure connection and simplify attachment and detachment between electrodes on a power feeding side and a power receiving side by bringing a terminal as the power receiving electrode for a load unit into pressure contact with a helical spring as the power feeding electrode, and feeding/receiving a high voltage between both units. CONSTITUTION:A helical spring 134 is used for a power feeding electrode of a high voltage power source 113. A hole is formed at a predetermined point of a casing 110 made of synthetic resin in the power source. The end of the spring 134 for the power feeding electrode and a metal plate 132 connected to the high voltage power source 113 cannot be connected directly to the casing 110, into which a sleeve 131 with a metal flange is driven in. At both ends of the through hole of the sleeve 131, a small screw 133 is inserted into the through hole of the sleeve 131 in contact with the end of the spring 134 and the surface of the metal plate 132. A screw part is inserted into a screw hole formed at the surface of the metal plate 132 with a head part pressing the end of the spring 134 so that a unit including a power feeding electrode with which the spring 134 and the metal plate 132 are engaged via the sleeve 131 is formed. Consequently, it is possible to securely connect the power feeding electrode to the power source with ease in the intermediate connecting portion between the high voltage power source and a load unit.

Title: Image forming device
Inventor: YAMANISHI HIDEKAZU
IPC: H04N1/407
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To properly perform an automatic density adjustment even when a document cover is opened so as to provide a good copy image by preparing a histogram from image data, correcting the image data, based on the histogram, and adjusting the density, based on the correction. SOLUTION: A histogram preparation circuit 80 prepares a histogram of density according to image data from a scanner part 1. Also a correction reference value calculation part 81 calculates a correction reference value, based on a histogram prepared in the histogram preparation circuit 80. In addition, a range correction circuit 82 corrects a density range using the correction reference value from the correction reference value calculation part 81 so as to automatically adjust the density at real time. Thus, because the histogram can be prepared by prescanning operation without performing data sampling from those parts other than documents, the density can be adjusted automatically by a proper correction reference value.

In the case when the moisture value measured thereby is judged to be the moisture value set on the higher side or below, it is judged whether or not the high moisture value set by the set moisture switch 30 is the prescribed value or above, and when YES, it is judged whether or not a determined moisture value obtained by taking account of nonuniformity on the high moisture side is below the prescribed value.  In the case of YES, drying is continued with the temperature of hot air in a cooling process set at an ordinary temperature or a low temperature below the ordinary temperature +10 deg.C so as to lower the temperature of grain. Thereafter a processing of an automatic stop control is executed and the drying is ended.

Filed: 1992-07-23
Abstract: PURPOSE:To obtain a smoke discharging system through pressurization, which is capable of preventing the diffusion of smoke as well as the flowing of the smoke into an escape passage and securing the safety of the escape passage. CONSTITUTION:When fire occurs in a living room 10, an annexed room 14 in a floor whereat the fire has occurred is pressurized by supplying air through an air supplying port 18. Accordingly, air stream in the annexed room 14 begins to flow toward the living room 10, in which an atmospheric pressure is low, by a pressure difference. In this case, an air stream, which flows from the annexed room 14 into the living room 10, is generated in a building. According to this air stream, smoke, generated upon fire, flows toward the living room 10 while riding on the air stream and is discharged to the outside of the building through an opened pressure releasing port 26. Accordingly, the smoke flows to the opposite direction of the escaping direction of inhabitants whereby the smoke will never bother the escaping of the inhanitants and the smoke will never be diffused.

Title: Method for detecting very small amount of fluorine gas
Inventor: HIRANO YOSHIBUMI
IPC: G01N31/00
Filed: 1990-07-27
Abstract: PURPOSE:To simply detect a very small amount of fluorine gas by detecting a crystal arising from the chemical reaction between fluorine gas in a gas and a silicon wafer, putting the wafer having ammonia molecules adsorbed, in a sample gas. CONSTITUTION:A silicon wafer having absorbed ammonia molecules is put in a sample gas and a crystal arising from the chemical reaction between fluorine gas in the gas and the wafer is detected with a wafer surface defect inspection apparatus. The fluorine reacts with the natural oxidation film SiO4 on the wefer surface as follows if fluorine exists in the gas; 4HF+SiO2 SiF4+2H2 O. Hexafluorosilicic acid arises by this SiF4 and the fluorine, and ammonium hexafluorosilicate is formed by the reaction with ammonia further. This product appears as a foreign matter on the wafer because it forms the crystal of a cubic system. The existence of fluorine can be judged if this foreign matter is detected by the wafer surface defect inspection apparatus of a light scattering method.
