Title: Oversampling-type a/d conversion circuit
Inventor: SAKAI KAZUNORI
IPC: H03M1/52
Filed: 1990-02-02
Abstract: PURPOSE:To improve the precision of A/D conversion by preparing positive and negative capacitors charging a return reference voltage, always charging positive or negative reference voltage in respective capacitors and allocating most oversampling clocks to integration time in an analog integrator. CONSTITUTION:An inputted analog signal operates switches S1-S7 in accordance with a control signal outputted from a control circuit 5 in a first adder 2. In a period when the positive or negative reference voltage and an external clock 6 are high, the outputs are added. A first analog integrator 3 integrates the outputs in the period when the external clock 6 is high. Furthermore, said outputs are added in a second adder 2 in the period when the positive or negative reference voltage and the external clock 6 are low. A second integrator 3 integrates the output of the second adder 2 in the period when the external clock 6 is low. Consequently, charging time when the reference voltage or an input signal are charged to the capacitors in an effective sampling clock can be ignored.

Title: Electric contact point material
Inventor: TAKAHASHI HIRONORI
IPC: H01H1/023
Filed: 1993-01-20
Abstract: PURPOSE:To improve stickiness resistance and consumption resistance while heightening hardness of a contact part surface, reduce and stabilize contact resistance, and improve environment resistance by forming a PdZn inter-metallic compound layer or the like on the contact part surface of a prescribed Pd contact point material. CONSTITUTION:A PdZn inter-metallic compound layer or a PdZn inter-metallic compound dispersed layer is formed on a contact part surface of a Pd contact point material having the Pd content of not less than 25%. In this case, when the content is less than 25%, since a PdZn inter-metallic compound in the layer formed on the contact part surface of the contact point material is too little, contact point performance is not obtained sufficiently. Particularly in the case of the contact point material of Pd alloy having the Pd content of 30%-60%, the PdZn inter-metallic compound layer or the PdZn inter-metallic compound dispersed layer is formed in uniform thickness on the contact part surface, thickness control becomes also easy. Thereby, since environment resistance becomes excellent and hardness becomes great as well, stickiness resistance and consumption resistance become also excellent. Since a crystal structure is regulated, electrical conductivity becomes excellent, so that contact resistance can be also reduced and stabilized.

Filed: 1987-02-04
Abstract: PURPOSE:To detect only the true band by determining whether the peak detected in the direction perpendicular to a sepn. development direction is the peak to indicate the true band or noise on the many rasters formed with one sepn. development array. CONSTITUTION:Two or more one-dimensional waveforms (rasters) consisting of the position along a migration direction and the level of the signal are formed with one sepn. development array. The peaks are then detected on all the rasters. Whether the peak exists or not within the specified range centering at the peak of one peak on one raster on the adjacent rasters is then retrieved with respect to said one peak. the retrieval of the peak on the adjacent rasters is thereafter successively repeated as far as the peak is found out. Determination is made that the band exists in the positions of a series of the peaks, if the peaks are detected on plural pieces of the rasters adjacent to each other. The base sequence of nucleic acid is thus easily and automatically determined with high accuracy.
