Title: Image reproducing device
Inventor: IZUMI HIROKI
IPC: G03G15/34
Filed: 1981-07-30
Abstract: PURPOSE:To increase the contact area of a multistylus electrode and toner and to improve the efficiency of injecting electric charge by injecting the electric charge while oscillating the multistylus electrode which forms electric charge patterns. CONSTITUTION:A toner 2 having the property of holding high resistance electric charge in a hopper 3 is supplied to a donor member 1 and the toner 2 is regulated to a uniform thin film by a doctor electrode 4. Electric charge patterns are formed on the thin film of the toner on the part 1 by a multistylus electrode 7 of which the leading end abuts on the part 1. The electrode 7 is driven by a rotating permanent magnet 13 and injects electric charge under oscillation. The contact area of the electrode 7 with the toner 2 is increased by such injection of the electric charge under oscillation of the electrode 7. As a result, the efficiency of the electric charge injection is improved.

Abstract: PURPOSE: To prevent the generation of instability or lowering of membrane permeated flow rate by applying the treatment of removing fiber content from excessive sludge after the biological treatment and then applying the concentration treatment by means of membrane separation. CONSTITUTION: Raw liquid 1 containing sludge such as sewage is introduced into a biological treatment device 2, and bulky solids are settled and removed in a first settling tank, and then floating solids and soluble organic matters are removed by an aeration device, while activated sludge is recovered in a collection settling tank to separate excessive sludge. Also excessive sludge fed from the biological treatment device 2 is stored in a sludge storage tank 7, and then introduced into a fiber content removing device 13. Then the excessive sludge from which the fiber content is removed is concentrated by a pressure filtration membrane of a membrane separation device 8. On the other hand, concentrated sludge is dehydrated together with the fiber content 14 by a dehydrator 9, and then dried by a drier 10 and burnt up in an incinerator 11.  Then, membrane permeated water 12 is fed into an aeration tank in the biological treatment device 2 and aerated again.

Filed: 1984-06-13
Abstract: PURPOSE:To detect original size effectively and efficiently by providing an original size selecting means which selects a line sensor or paper feed sensor automatically and exclusively. CONSTITUTION:When a copy key 56 is depressed, a main control part 51 judges whether or not a copy is taken by using an automatic original feeding device 54. When not, it is checked whether an original is set correctly or not and when the original is set correctly, the line sensor 36 gathers original information (original length, original density, etc.) and also sends it to the main control part 51 through an amplifier 52 and an A/D converter 53. The main control part 51 decides on the orignal size from the original information and displays the size on a display part 58. When the copy is taken by using the device 54, on the other hand, a paper feed sensor 44 detects the original being passed and also detects the other length of the original from the passing time to send it to a subcontrol part 55. Then, the subcontrol part 55 sends the detected original size to the main control part 51, which displays the orignal size on the display part 58.

Title: Shearing work method and device therefor
Inventor: KOBAYASHI TAKESHI
IPC: B23D36/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To avoid a back gage device by a simple mechanism when drawing forward a product. SOLUTION: A ram 19 is positioned in a first top dead center by a first detection LS43 at workpiece positioning time, to make a workpiece W run against a back gage device 27. The ram 19 is lowered down, and a return conveyer 39 is lowered down at shearing work time. A sheared product is dropped down onto the return conveyer 39. Since the ram 19 is lifted to a second top dead center in the upward position distant by a thickness or more of the workpiece from the first top dead center by a second detection LS45 when lifting the ram 19 after shearing work, a space of the thickness or more of the workpiece W is generated between the gage device 27 and an upper surface of the return conveyer 39 reset to the original position. Even if the back gage device 27 is positioned downward of the ram 19, the product on the return conveyer 39 is prevented from running against back gage device 27.  Narrow width shearing work like a narrow paper tablet can be easily performed, a product can be easily drawn forward.

Title: Operating device for switch
Inventor: NAKAHATA MINORU
IPC: H01H33/40
Filed: 1988-05-17
Abstract: PURPOSE:To make an operating device for a spring driven switch free from application of an excessive operating force to a spring driven section by installing a clutch mechanism to release an operating section from the spring driven section. CONSTITUTION:In an operating section 47, pawls 51a and 51b, a link 52 and guide rollers 55a and 55b which form a quadric link and a guide 57 form a clutch mechanism, and take part in releasing the operating section 47 from a spring driven section 34. When an operating shaft 49 is caused to make, for example, a counterclockwise circular motion, the operating section 47 also makes a counterclockwise circular motion with the result that an end of a cam shaft pin 45 is pushed by the link 52. The operating section 47 is released from the spring driven section 34 through a motion of the quadric link by further continuing that circular motion. Resultantly, the operating section 47 can make idling, and even if an excessive operating force is applied to the spring driven section for such reasons as a malfunction of a driven section, the spring driven section is safe.

IPC: F23D11/24
Filed: 1985-06-03
Abstract: PURPOSE:To prevent the nozzle from being blocked by cooling the nozzle part by a part of whole combustion air. CONSTITUTION:Steady temperature air of 2-20% of the whole combustion air is supplied from an air nozzle 16 between air nozzles 20 for supplying pre-combustion air through a cooling air supply port 18 in the periphery of a central oil nozzle 14 for supplying fuel oil. On the other hand, by operating an operating handle 29 to open a cock of an oil adjusting mechanism in a predetermined amount, and oil is supplied from an oil supply port 15 to an oil nozzle 14. In this manner, cooling air of 2-20% of the whole combustion air quantity constantly flows to the outside of the oil nozzle 14 to cool and protect the oil nozzle 14. Hence, even when oil of heavy quality is used as a fuel oil and its supply amount is decreased or turned OFF, oil is not carbonized within the oil nozzle 14 and does not block the nozzle.

IPC: D06H5/00
Filed: 1984-06-13
Abstract: PURPOSE:A sheet in the roll form is cut into strips and the strip sheets are unrolled in parallel and the sheets are sewed with adjacent strips to give connected sheets of increased commodity values in high productivity. CONSTITUTION:For example, a sheet of waste artificial leather after removing defect parts are rolled around a mandrel pipe 9 and the resultant roll is cut perpendicularly to the mandrel into strips. A plurality of strips in the roll form 3 are unrolled so that faces of side ends oppose to end faces of adjacent strips and the strips are sewed by threading across the interfaces in zigzag with a machine. At this time, the needle thread 14a and the bobbin thread 14b are allowed to form round knots 15 to prevent them to untying whereby a strip sheet of high commodity values is obtained. The resultant strip sheet can be rolled up widthwise and the roll is cut into strips and a variety of strips different in shape and color are used to form sheets with patterns of increased commodity values.
