Title: Image forming device
Inventor: OSAWA IKUO
IPC: B65H11/00
Filed: 1994-02-23
Abstract: PURPOSE:To reduce the entire size of an image forming device by disposing both a paper feeding cassette and a manual paper feed part in such a manner that they may not be protruded from a device body. CONSTITUTION:In the case where jamming has occurred between a paper feed roller 17 and a register roller 4, a guide surface 47 in the inner wall of a cassette front wall 32 is released easily only by drawing a paper feed cassette 2, thus making an action for correcting jamming extremely easy. When paper is fed manually, a recording paper placing surface, in which the paper feeding surface of a paper feeding table 341 and a register guide passage 19 leading to the inlet end of the register roller 4 on the device body side are communicated with each other in a roughly straight line, is formed by drawing the manual paper feeding table 341 from the cassette front wall 32 and laying it to roughly horizontality so that the lower surface of the paper feeding table 341 may be brought into contact with the upper end of the front wall 32. Thereafter, a width regulating plate 342 is then moved to a prescribed position, and recording paper of a desired size is inserted up to the inlet end of the resister roller 4 from the manual paper feeding table 341 and the register guide passage 19, thereby bringing the device into a stand-by status for image forming operation.

Title: Hydrolysis of sulfonate in hydrocarbon substrate and recovery of corresponding sulfonic acid
Inventor: HOMMELTOFT SVEN IVAR
IPC: C07C303/20
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To efficiently perform hydrolysis and recovery of a sulfonate or sulfonic acid by hydrolyzing a sulfonate by bringing a hydrocarbon into contact with an aqueous phase containing an ammonium salt and recovering sulfonic acid by separating an aqueous phase from a hydrocarbon substrate. SOLUTION: In a method for hydrolyzing a sulfonate (e.g. fluorinated alkyl sulfonate, especially an ester of trifluoromethane sulfonic acid) in a hydrocarbon substrate by an aqueous extraction of a hydrocarbon substrate, sulfonic acid is recovered by bringing a hydrocarbon into contact with an aqueous phase containing an ammonium salt (preferably an alkylammonium salt especially a trialkyl or a tetraalkyl ammonium salt) and separating an aqueous phase from the hydrocarbon substrate by hydrolyzing the sulfonate to a corresponding sulfonic acid thereby. The method is especially useful for recovering fluorinated alkyl sulfonic acid from a flow discharged from an alkylation of acid-catalyzed hydrocarbon.

Title: Manufacture of semiconductor device
Inventor: ISHIDA TOMOHIRO
IPC: H01L21/285
Filed: 1988-03-02
Abstract: PURPOSE:To supply only the desired main surface of a semiconductor substrate with a reaction gas and to shorten the processing time of a metallic film, by previously forming a substrate coating film comprising an insulating film on either one or both of the side face and another main surface of the semiconductor substrate. CONSTITUTION:A substrate coating film 2 consisting of an insulating film such as an silicon dioxide film is deposited on the whole surface of a semiconductor substrate 1. Contact holes 3 are bored to the substrate coating film 2 shaped onto the main surface of the semiconductor substrate 1 through a photoengraving technique. Metallic films 4 are deposited only in the contact holes 3 through a selective metallic CVD method. Accordingly, since the side faces and rear of the semiconductor substrate 1 are coated with the insulating film, a reaction gas supplied is consumed only on the main surface of the semiconductor substrate 1, thus improving a deposition ration, then shortening the deposition time.

Abstract: PURPOSE:To enable rational and automatic control, by measuring the distributions of sludge concn. in the depth in a sepn. tank, comparing the sludge concn. and the reference concn. of effluent, calculating the possible rates of the respective removal and extraction and controlling said rates. CONSTITUTION:A sludge distribution meter 13 provided to a sepn. tank 5 feeds the measured value of a sludge concn. D with respect to a depth H at prescribed sampling periods to a control device 14. The amt. QR of effluent and the integrated amt. QS of sludge are calculated there, then one of extraction valves 7A-7C is selected from the measured value of distributions. The possible extraction rate QRA of the effluent is determined in accordance with said value and said extraction valve is opened. The valve is closed when the actual rate of extraction as detected with a flow rate detector 12 attains the QRA. The possible rate QSA of removal of concd. sludge is determined by subtracting the min. rate QSMIN of concd. sludge that takes the return of seed sludge, etc. into consideration from the QS, and a removing pump 9 is driven at said rate. When the actual rate of removed as detected with a flow rate detector 11 attains the QSA, the pump is stopped. Thus, the sludge digestion installation is controlled rationally.

Abstract: PURPOSE:To facilitate the expansion and reduction of a decentralized control system by adopting a constitution so that an address value and a constant defined by a system are registered and erased by a request from various other terminal equipments. CONSTITUTION:Controllers 6, 8 reply the state information of terminal equipments 5, 7 in response to the command of a system controller 3. Since the reply is accompanied with the address of the controllers 6, 8, a processing is executed so that its terminal equipment is registered or not as an effective terminal equipment based on an address-terminal equipment conversion list registered in advance in the controller 3. The controller 3 transmits an equipment state read notice periodically and when the terminal equipment 9 is connected newly, the controller 10 replies the state of the terminal equipment 9 to the controller 3. When the status information is normal, the terminal is registered as the effective terminal equipment, and the address-terminal equipment conversion list registered and defined in the controller 3 is displayed on a display device by the input from an input equipment 4, and the address value of the terminal equipment defined in each terminal equipment is varied by operating the equipment 4 to revise the address.

Title: Electrophotographic device having plural developing devices
Inventor: SENBA HISAAKI
IPC: G03G15/08
Filed: 1985-03-14
Abstract: PURPOSE:To suppress easily the mixture of different colors while the spatter of a developer is suppressed from a developer at the down stream side by disposing plural developing devices in the order of the developer controlled, so that the charge quantity of the developer can be larger, from the upstream side of the rotation of a picture carrier. CONSTITUTION:In order to suppress the spatter of the developer in the direction of a toner photosensitive body 1 on the sleeve 5a of the developing device 5 at the downstream, a higher current V than the surface current V0 of the photosensitive surface is always given to the developing device 5. In such a state, since an electric field E of (V-V0)/d arises between sleeve photosensitive surfaces, the toner image on the photosensitive surface generates a peeling off force F0 in the direction of the sleeve 5a of the developing unit 5 due to the electric field (d: interval between them). However, since the charge quantity of the toner image developed by the developing device 4 is larger than that of the developing device 5, the image force of an adhesive F is sufficiently large and the relationship F>F0 can be established. Namely the charge quantity of the toner of the developing device at the upstream side is set larger than that at the downstream side, whereby the spatter to the downstream developing device and color mixture can be prevented.
