IPC: H04N19/42
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To make detectable a differential image selectively including only an subject of which the speed of changing the image is settled within a desired range, by extracting the image by selecting pixels, which belong to the desired range of count values, among respective outputted pixels. SOLUTION: A reference image storage means 012 stores and reads out a reference image. An update image storage means 004 updates and reads out the memory corresponding to update image signals to be time sequentially and successively inputted. A comparing means 013 compares the reference image signal stored in the reference image storage means 012 with the signal of time sequentially and successively inputted update image information for every pixel and time sequentially and successively judges the presence/absence of significant difference for each pixel. A counting means 014 counts the frequency of changing the judgement on the presence/absence of significant difference judged by the comparing means for every pixel with the set time.  Then, an image extracting means 005 extracts the image by selecting the pixels, which belong to the desired range of count values, out of the count values of respective pixels outputted from the counting means 014 among the images stored in the update image storage means 004.

Title: Collector head for pantograph
Inventor: SHIBAYAMA KUNIO
IPC: B60L5/24
Filed: 1990-01-31
Abstract: PURPOSE:To reduce maintenance cost by constituting a collector head of a linear section to be fixed with a sliding board and horn sections at the opposite ends, separated from one another, thereby enabling replacement of only the consumable section, i.e. the linear section. CONSTITUTION:A sliding board 3 is fixed to the upper part of the linear section 1 of a collector head. Fixing metals 4 are secured to the opposite ends of the linear section and a fixing section to be mounted on a horn section 2 is coupled through a screw 6 with the fixing metal 4. The linear section 1 has U-shaped cross section and the fixing metal 4 also has a U-shaped cross section. The linear section 1 and the fixing metal 4 are secured through rivets. At this time, the linear section 1 to be fixed with the sliding board 3 and the horn sections 2 at the opposite ends are provided independently. Consequently, upon consumption of the linear section 1, the linear section 1 is uncoupled from the horn section and only the linear section 1 is replaced. According to this method, maintenance cost can be reduced and the horn section can be used repeatedly.

Title: Device for purifying foul water
Inventor: YOSHIDA MASAYUKI
IPC: C02F3/06
Filed: 1978-02-28
Abstract: PURPOSE: To maintain activated sludge on fixed beds in an aerobic state and dispose of high-concentration organic waste water, by coating the activated sludge on porous pieces to form the fixed beds and arranging the fixed beds perpendiculary or radially to baffles in an aeration vessel.  
     CONSTITUTION: The organic waste water is introduced into the aeration vessel 1 to a level higher than the top of the baffles 5. An air dispersing unit 3 is started to supply compressed air from air dispersing pipes 4 into the aeration vessel. The compressed air flows up as bubbles along the baffles 5 and lifts the waste water. Then, the waste water enters into a disposal chamber 7 and swirls downward. Since the fixed beds 8 are oriented perpendicularly or radially to the baffles 5, the waste water is kept from partially flowing and oxygen is uniformly supplied to the entire fixed beds 8. Because the waste water swirls downward between the fixed beds 8, old sludge falls off not to clog.

Title: Production of electrophotographic sensitive body
Inventor: TANIGUCHI HIDEAKI
IPC: G03G5/05
Filed: 1992-02-07
Abstract: PURPOSE:To obtain the electrophotographic sensitive body free from unequal drying and clouding at a high non-defective rate by mounting such a heater which is higher in temp. in the lower part and is lower in temp. nearer the upper part inside a conductive base body and subjecting the base body to dip coating of a coating liquid for the photosensitive body. CONSTITUTION:The conductive base body 1 suspended by a lifting machine 2 is lowered with a lifting motor 3 and is dipped into a coating tank contg. a coating liquid 5. A heater is mounted in the conductive base body. This heater is constituted of three kinds of surface heaters having a low calorific value for the upper part A, a high calorific value for the lower part C and an intermediate calorific value for the intermediate part B. The temp. of the base body falls successively at the time of pulling up the base body 1 which is completely dipped and, therefore, the temp. thereof is compensated by three kinds of these surface heaters. The temp. over the entire surface of the base body is thus uniformly maintained before the solvent of the coating liquid evaporates and dries.

Title: Production of photosensitive resin plate
Inventor: OGAWA NOBUO
IPC: G03F7/40
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To stably produce a plate with low tackiness by exchanging the water used in a post-exposure process for every two or less plates. SOLUTION: By the study of insufficient post-exposure due to contamination of a post-exposure water, it is found that after three plates are treated, the water has 70% transmittance for UV rays of >=300nm wavelengths, 5% transmittance for UV rays of <=300nm wavelengths, and especially, the most of sterilizing rays can not reach to the plate surface after three plates are treated. This is because a material depositing on the plate surface pollutes the post-exposure water, and as a result, transmittance for UV rays and sterilizing rays in the water is decreased. To prevent the decrease in the transmittance, the post- exposure water is exchanged for every two or less plates, or water is always supplied and discharged. Thus, contamination in the post-exposure water can be suppressed to the min.  By this method, the decrease in the transmittance for UV rays of >300nm wavelengths and sterilizing rays can be prevented and the tackiness of the surface of a printing plate can be decreased.

Filed: 1981-02-20
Abstract: PURPOSE:To manufacture the device having a desired impurity profile efficiently in a short time by implanting ions having low concentration at two or more of plural times while changing energy in a junction forming process through ion  implantation. CONSTITUTION:Two conductive type determined impurities are formed to the main surface of one conductive type substrate through the ion implantation, and the device having a P-N junction is manufactured in the substrate. In the ion implanting process, ions are implanted at times such as twice when the concentration of the surface and concentration near the junction can be brought to desired values through the implantation of a condition such as 100kev, 5X10<15>cm<-2>. Primary implantation is executed at a condition such as 150kev, 7X10<13>cm<-2>, and secondary implantation is executed under the condition of 40kev, 6X10<13>cm<-2>.  Accordingly, since the profile equal to the case when ions are implanted once  can be formed, th process can be completed in a short time even when using a low current implanting device, and the efficiency of the device can be improved.
