Title: Method and device for collecting intermittent state information for telecommunication line
Inventor: KOBAYASHI YOSHIICHI
IPC: H04B3/46
Filed: 1990-03-30
Abstract: PURPOSE:To store the information of a time and a line state successively by a detecting the state of the voltage and that of the current of a telecommunication line, storing them in a memory part after converting to digital information, and comparing the detected digital data of the state of the voltage and that of the current with contents in the memory part detected previously. CONSTITUTION:A detecting part 10 detects the voltage applied to the telecommunication line 500, and sends the state of the line to an analog/digital conversion part 30, and a detecting part 20 sends the detected state of the current to an analog/digital conversion part 40. A CPU part 50 for control recognizes and confirms the digital information of the state of the voltage and that of the current obtained from the analog/digital conversion parts 30, 40, and sends them to the memory part 60. Also, the CPU part 50 for control receives the information detected successively, and compares it with the content stored in the memory part 60 received previously, and no information is written on the memory part 60 if it is changed within a specific range, and the information is written newly on the memory part 60 if change outside the specific range occurs. Thereby, it is possible to always monitor an electrical state applied to the telecommunication line.

Title: Production of maleimides
Inventor: YAMAMOTO TOSHIHIDE
IPC: C07D207/448
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To readily obtain maleimides used as an intermediate raw material for medicines and agricultural chemicals and useful as a raw material for various kinds of polymer compounds and a curing agent for rubbers by a simple operation. SOLUTION: An N-Carbnamoylmaleimide of formula I (R<1> and R<2> are each H, a halogen, a 1-10C alkyl or an aryl or R<1> and R<2> together form a cyclic substituent group by C-C bond) is subjected to decarbamoylation in the presence of a tertiary amine (e.g. triethylamine) in a solvent (e.g. ethyl acetate) at 60-150 deg.C to provide the objective maleimides of formula II. The resultant maleimide is separated from cyanuric acid obtained as a by-product by filtration and washed with water and the solvent is distilled away therefrom to provide the objective high-purity maleimide. In the method, decarbamoyl reaction is advanced even if a solvent except DMF difficult to isolate is used to isolate high-purity maleimide. The tertiary amine is used in an amount of 0.1-30wt.% based on the compound of formula I.

Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To form a stable image by not having deteriorated toner returned again to a developing chamber that is not provided for developing remain in the developing chamber with a simple constitution. SOLUTION: In this device, a lower side partition wall 54 that defines a bottom end of an opening part 52 by which a toner containing chamber 27 of a developing cartridge 36 and the developing chamber 51 are communicated is formed so that height of both end parts 57 are lower than height of its central part 56. Thus, in the opening part 52, since more quantity of toner can be returned to the toner containing chamber 27 in both end parts than in the central part, the deteriorated toner that is not provided for developing but returned to both end parts of the developing chamber 51 again can be circulated within the developing cartridge 36 without having it remain within the developing chamber 51.

Title: Electrophotographic method
Inventor: MIYAGAWA NOBUHIRO
IPC: G03G21/00
Filed: 1983-05-12
Abstract: PURPOSE:To prevent deformation of an image by heating an amorphous silicon type photoconductor layer on the surface of a photosensitive body before or after the end of the processes of electrostatic charging, imagewise exposure, etc. CONSTITUTION:An amorphous silicon type photoconductor layer 2 formed on the surface of a photosensitive drum 1 is heated at least once before or after the end of the processes of charging, imagewise exposure, etc. As a result, no image deformation occurs when copying is continued after the heating or after the lapse of a prescribed time from it. This heating is easily executed by installing a heating mechanism, such as a heating roller 15, bringing it into contact with the layer 2, and idly rotating the drum 1, and it is desirable to heat the layer 2 at 40-200 deg.C. Consequently, the deformation of an image is prevented.

Filed: 1980-06-17
Abstract: PURPOSE:To save energy and improve the productivity of finish annealing by preheating the coil to be annealed of a directional electrical steel contg. Si from the end face of the coil then subjecting the same to finish annealing. CONSTITUTION:After a directional electrical steel contg. <=4.0% Si is hot rolled, it is subjected to cold rolling and annealing more than once.

Patent JP-S567123-A (JP)
Title: Switching regulator
Inventor: FUKUYAMA TOSHIBUMI
IPC: H02M3/155
Filed: 1979-06-27
Abstract: PURPOSE: To increase the constant voltage characteristics as well as reduce the  power loss with a simple circuit constitution, by providing the switching transistor,  the error amplifying part of 2-step amplification, the smoothing circuit and others.  
     CONSTITUTION: With the short circuit given between output terminals t 01  and t 02 , switching transistor 2 is cut off. Thus such accident as to burn up transistor 2 due to the overcurrent can be avoided. When the short failure is released, a slight amount of current flows through resistance 17. And thus voltage V 0  of terminals t 01  and t 02  increase slightly by voltage ΔV, and accordingly the base voltage of transistor 11b of the next step also increases by ΔV. As a result, the collector current of transistor 11b flows, and then the collector current of transistor 2 also flows. As a result, the voltage of t 01  and t 02  increases more up to normal output voltage V 0 . Furthermore, the constant voltage characteristics of V 0  is flat and good since  no resistance for current detection is incorporated.

According to the constitution, the through hole 3 is filled thoroughly with the plug 4 even if the aspect ratio is high. Furthermore, since the first wiring layer 2 and the plug 2 are made of same material, perfect contact is achieved between them resulting in the enhancement of reliability of wiring.
