Title: Device for cleaning fixing device
Inventor: FUKAO HIROSHI
IPC: G03G15/20
Filed: 1987-01-13
Abstract: PURPOSE:To prevent the generation of oil staining due to the change of a paper feeding mode by constituting an oil coating cleaning roll of a high application part having much oil application, a low application part having little oil application and an interrupting part for interrupting the movement of oil in these and low application parts. CONSTITUTION:An oil containing layer 6 in the oil coating cleaning roll 4 is constituted of the high application part 7 containing much oil in a longitudinal direction, the low application part 8 containing oil less than that of the part 7 and the interrupting part 9 to be a border between the parts 7, 8. Even if paper with small size is continuously fed, a trouble stagnating much oil in a common paper part can be removed. Even if paper with large size is suddenly fed, the generation of oil staining can be prevented by the synergetic effect of the interrupting part 9 and the low application part 8.

Title: Production of superconducting material
Inventor: NAKAMORI TOMOHIRO
IPC: C04B35/00
Filed: 1988-01-18
Abstract: PURPOSE:To obtain a superconducting material having high critical temperature at a low calcination temperature and short calcination period, by coprecipitating a salt of a specific rare-earth metal together with a Cu salt and Ba hydroxide, forming the coprecipitated powder and calcining the formed product. CONSTITUTION:An alkali is added to a mixed aqueous solution of a salt of one or more rare-earth elements selected from Sc, Y, La, Ce, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu, a Cu salt and a Ba salt to coprecipitate the hydroxides of the rare-earth element, Cu and Ba. The precipitate is washed, dried and pulverized to obtain a coprecipitate powder. The powder is formed and calcined at 800-1000 deg.C to obtain the objective superconducting material. A superconducting material can be produced at a calcination temperature of >=800 deg.C by this process. The calcination time is as short as 2hr when calcined at 950 deg.C and a superconducting material having sufficiently high critical temperature (i.e. 90K) can be produced.

Title: Hollow forming method
Inventor: NAGAI SUMIO
IPC: B29C49/50
Filed: 1984-01-20
Abstract: PURPOSE:To enable to simply cut manually at a collapsing portion after molding by closing molds, blowing pressure fluid into a parison, moving part of molds to form a gap communicating with atmosphere, swelling to deform part of the parison in the gap, thereby reducing the thickness, and then collapsing to break this portion by the pressure in the parison. CONSTITUTION:Air is press-filled into a parison in the state that split molds 1b are contacted without gap to a mold body 1a to form a hollow portion. Immediately thereafter the mold 1b is moved, separated from the body 1a, and a small gap S is opened in the inner surface of the cavity 3. At this time the parison in the cavity 3 is cured in contact with the inner wall of the cavity 3. Accordingly, only the portion opposed to the gap S is expanded, deformed, and reduced in thickness and eventually collapsed by the internal pressure in the portion.

Filed: 1993-01-20
Abstract: PURPOSE:To improve the heat radiation of the hybrid optical integrated circuit and to eliminate the peeling and optical axis mis-alignment by heat cycles by forming a semiconductor laser and optical parts consisting of waveguides of LiNbO3 and LiTaO3 by hybrid integration on a substrate consisting of SiC, AIN or diamond. CONSTITUTION:The semiconductor laser 2 and the LiTaO3 waveguide 3 are directly coupled on the SiC substrate 1 by disposing the active layer 4 of the semiconductor laser 2 and the waveguide layer 5 of the LiTaO3 waveguide 3 on a lower side. The need for position adjustment of a Z-axis on the basis of the reference plane is eliminated and the position adjustment is carried out while the output power of guided light is monitored only in the x-axis direction and the y-axis direction in order to optically couple the exit light from the semiconductor laser 2 to the waveguide layer 5. Fixing of the LiTaO3 waveguide 3 and the SiC substrate 1 is executed by soldering after the optical axis adjustment. As a result, the substrate which has the good thermal conductivity and radiates heats well is obtd. The optical integrated circuit which functions stably even if the high-output semiconductor laser is used is obtd.

Title: Ventilation air conditioning system for nuclear power plant
Inventor: KUBOTA RYUJI
IPC: G21F9/00
Filed: 1988-01-18
Abstract: PURPOSE:To prevent a reactor from shutting down by switching an ordinary operation to the operation of a recirculation system by the 'OR' of the abnormality signal in the other nuclear power plant and the radiation high signal on the air feed side in the ventilation air conditioning system of one's own nuclear power plant. CONSTITUTION:The reactor level low signal and reactor container pressure high signal in the adjacent other nuclear power plant are generated in the event of outbreak of the loss of coolant accident in said other nuclear power plant. Further, a valve 9 and a valve 12 installed on the down stream side of a detector 17 are closed and a valve 14 is simultaneously opened, by which the operation is switched to the recirculation system when the radiation high signal in a radiation detector 17 of the air feed system in one's own nuclear power plant is received. The reactor building of one's own nuclear power plant is thereby isolated from the outdoor air and, therefore, the operation of the radioactivity high signal of the ventilation air conditioning system of the reactor building and the radioactivity high signal of the exhaust air in the fuel replacement area of the reactor building does not take place. The switching of one's own nuclear power plant to the emergency ventilation air system by the loss of coolant accident of the other nuclear power plant is, therefore, prevented.

Title: Signal processing system for digital vtr
Inventor: NAGOYA TETSUO
IPC: G11B5/09
Filed: 1987-01-19
Abstract: PURPOSE:To prevent an over-looked error rate from increasing and to prevent the deterioration of the quality of a reproduced picture by constituting the titled system so that an error detection/correction circuit prohibits both error detection action and correction action when a flag showing a transition time is present, and treating all the data as error data. CONSTITUTION:A flag 10 outputted from a frame synchronization detection/ protection circuit 2, goes to '1' at an asynchronized status S0, S1 of the frame synchronization, and transmitted to an internal code decoding circuit 8 via an ID correction circuit 4 and a time base corrector 6. In the circuit 8, at a time when a flag 12(10) is in '1'-status, the error detection and the correction of an internal code are prohibited, and all the reproduced data at this time are processed as error data. However, if a synchronization pattern can not be detected in a synchronized status, the status shifts from S2 to S3, S4, S5, and S6, and the S3-S6 execute the rear-part protection function.

Title: Data exchange controlling system
Inventor: FURUKAWA NOBORU
Filed: 1987-01-19
Abstract: PURPOSE:To execute appropriate calling control by setting a waiting time until a called response responds from a called terminal, in accordance with a state of its called terminal designated from a calling terminal. CONSTITUTION:When a terminal equipment T1 calls a terminal equipment T2, a control part 4 outputs a called instruction signal to the terminal equipment T2 in accordance with a calling request from the terminal equipment T1. Subsequently, the control part 4 sets a called response waiting time in accordance with a state of the cases when the terminal equipment T2 which has received the called instruction signal is generating a fault, or when there is no fault and a local operation which is ended in a short time is being executed, etc. When the waiting has elapsed, its call is cut. In such a way, an unnecessary recall of the calling side and the response waiting time can be reduced, and appropriate calling control can be executed.
