IPC: H01L27/04
Filed: 1986-07-14
Abstract: PURPOSE:To achieve an automatic switching between an internal signal and an external signal inputted at an input terminal, by adding a detection circuit for detecting a floating state to an input terminal of a semiconductor integrated circuit to perform a self-detection of the floating state. CONSTITUTION:This circuit is provided with a detection circuit 5 to detect a floating state of an input terminal 10 and a switching circuit 6. With the terminal 10 under the application of a voltage, namely, at a power source voltage VCC or at a ground GD level, a control signal VF maintains a VCC level and the GD level in inversion to open a transfer gate 2 and the level at the point A is outputted to the point B. When the floating state is not at the point A, that is, testing is not ready, none is connected to the terminal 10 with the potential unstable. The signal VF outputted from the circuit 5 maintains the GD level and the VCC level in inversion to open a transfer gate 3 and the level at the point C is outputted to the point B.

Abstract: PURPOSE:To collect U from a radioactive waste liquid at an extremely high efficiency by adding nitric acid to the radioactive waste liquid of sulphuric acid type or phosphoric acid type containing U and heavy metal such as Fe, and extracting the waste liquid using an extraction liquid containing tributyl phosphoric acid. CONSTITUTION:A strong acid as NO3 source such as HNO3 is mixed with a radioactive waste liquid A. To the waste liquid A an extraction solvent is added, which is prepared by diluting tributyl phosphoric acid TBP with a diluting solution such as n-dodecane, followed by shaking for a 5-6min period, and then the extraction solvent B is sampled immediately. At this time, complex salt UO2(NO3)2.2TBP is formed from U existing in the waste liquid A in the state of UO2<2+>, NO3 deriving from the HNO3 added to waste liquid A, and TBP mixed in the waste liquid A, and the U in the waste liquid A phase is collected at a high efficiency in the extraction solvent phase B. Further, one volume of pure water is added to one volume of the sampled solvent B1, and the U on the extraction solvent phase B side is counter-extracted to the pure water phase C side. Thereby U can be collected out of the waste liquid at an extremely high efficiency.

IPC: B65C9/42
Filed: 1994-06-24
Abstract: PURPOSE:To provide an image forming device which can prevent a self adhesive material on the edge of a labelling sheet from sticking to a drum or the like. CONSTITUTION:A powder applying means 16 to apply self adhesive material sticking preventive powder to the edge of a labelling sheet, is arranged in a sheet carrying passage between a sheet loading means and a printer engine 12. A sheet discriminating means 13 and a sheet edge detecting means 15 are connected to the powder applying means 16 through a control means.

IPC: H04N5/92
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a smooth reverse reproduction function in the case of reproducing a digital picture which is compressed/encoded by an MPEG system. SOLUTION: The picture which is processed by a demultiplex circuit 1, a variable length decoding circuit 2, an reverse quantization circuit 3 and an reverse discrete cosine transformation(IDCT) circuit 4 is down-sampled to the number of the picture elements of 1/M (M: positive integer) in a down sampling circuit 5.

Thus, all the pictures in one GOP can be stored in the memory 9, and the pictures are not required to be thinned. Thus, the smooth moving picture can be supplied at the time of inverse reproduction. Thus, the extension of a picture memory is not required.

Abstract: PROBLEM TO BE SOLVED: To conduct buffer re-assignment associated with deletion of a data area while keeping data transmission between processing systems in the common use buffer used for transmission of a plurality of data between two processing systems at a different transmission rate. SOLUTION: In the case of rearrangement of a data area used in a buffer, a buffer management section 13 sets a new start address 22A and a new end address 24A and requests the reallocation to a processing system 11. When a write pointer 25P reaches an end address 23A, the processing system 11 sets both the write pointer 25P and the start address 21A to the new start address 22A. A processing system 12 awaits it that a reach pointer 26P reaches the end address 23A again to set the read pointer 26P to the new start address 22A and replaces the end address 23A with the new end address 24A.
