Title: Deglitch circuit
Inventor: YOSHIDA MASAO
IPC: H03M1/08
Filed: 1985-10-18
Abstract: PURPOSE:To reduce the adverse effect onto a reproducing analog signal by connecting the 2nd switching means in parallel with the 1st switching means and making a control input of the 2nd switching means as an inverted signal to the control input of the 1st switching means. CONSTITUTION:A control signal C via an inverter 23 is applied to analog switches 21, 22 as a control input. Since the control signal and its inverting signal are fed respectively to the control input terminal of analog switches 9, 21 in the deglitch circuit 20, crosstalk noise of opposite polarity is generated in each output of the analog switches 9 and 21 and canceled together. Similarly, since the control signal C and its inverted signal are fed respectively to the control input terminal of the analog switches 10, 22, the outputs of the analog switches 10, 22 have crosstalk noises of opposite polarity and they are canceled together.

Title: Semiconductor photodetector
Inventor: SHIRAI TATSUAKI
IPC: H01L31/10
Filed: 1987-09-17
Abstract: PURPOSE:To utilize operating voltage more effectively, and to realize operation at high speed of an element by forming an n<+> type region as a field-drop layer on the intermediate layer side of the interface between an intermediate layer and an n-type InP layer. CONSTITUTION:An InP buffer layer 2, an InGaAs optical absorption layer 3 and an InGaAsP intermediate layer 4 are epitaxial-grown onto an n<+> type InP substrate 1 in succession. Si is introduced through selective ion implantation to shape an n<+> high concentration region 12, and an n-type InP layer 5 is grown in an epitaxial manner. Be ions are implanted to the InP layer 5 to form a p-type guard ring 7, and a p<+> region 8 is shaped through thermal diffusion using CdP2 as a source. Consequently, since the high concentration region as a field-drop region is shaped on the intermediate layer side, voltage sufficiently higher than the height of a barrier is applied to a hetero-junction between the layers 4, 5, and a hetero-junction to which specific voltage must be applied for operation at high speed is formed only between the layers 4, 3. Accordingly, supply voltage is utilized more effectively.

Title: Method for testing digital decoder and device for testing digital decoding means
Inventor: BOCK ALOIS
IPC: G01R31/317
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To test a decoder without separating a specific section of signal by producing a digital signal composed of trigger signal from a compressed digital signal, analyzing a part thereof to produce a waveform characteristic value, and then comparing the waveform characteristic value with a correct value from a decoder. SOLUTION: A decoder 1 under test decodes a compressed image bit stream (a) and a decompressed signal (b) is delivered to a trigger waveform detector 2 and a check sum adder 4. The waveform detector 2 generates a start pulse (c). A signature analyzer calculates the check sum of decompressed bit stream (b) only during the interval between the start pulse (c) and a stop pulse (d). A decoder 1 functioning insufficiently does not decode the trigger waveform at all or generates a signature. When no trigger waveform is detected, the signature check sum is sustained at zero to indicate presence of trouble. Appropriate operation of decoder can be verified sufficiently when the trigger waveform itself is detected.

Filed: 1986-10-01
Abstract: PURPOSE:To form a thick ceramic layer on a long-sized metal wall by repeating coating operation while cooling the metal wall from the outside so that formed coating layers are connected. CONSTITUTION:A powdery mixture of a highly reducing element with a metal oxide is filled into the hollow part of a metal tube under pressure and the upper part of the filled mixture is heated to initiate a thermit reaction. While the position of the tube is controlled, the reaction is allowed to proceed to form a thick ceramic layer between the surface of the resulting melt and the surface of the inner wall. The metal wall is cooled from the outside during the continuation of the reaction to prevent the temp. of the wall from rising. The above-mentioned coating operation is repeated so that formed ceramic layers are connected. By this method, a long-sized coating layer can be formed and the coated surface can be branched.
