Title: Thermoelectric conversion element
Inventor: TANJI YASUNORI
IPC: H01L35/16
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of thermoelectric conversion characteristics caused by sublimation and oxidation, etc., of an element in PbTe, for example and attain stable thermoelectric conversion for a long period by crowning at least a high temperature side end part of a thermo-element with a conductive block having a recessed part in which the end part is force-fitted. SOLUTION: Since edge parts 1H and 1L of a thermo-element 1 are crowned with a conductive block 3, the end part can be electrically and thermally combined to other parts by the conductive block 3. The thermo-element 1 and the conductive block 3 are combined by force-fitting a thermo-element end part to the recessed part 1 of the conductive block 3. Since there is a possibility of generation of a gap between a thermo-element and a conductive block microscopically, generation of heat shearing stress can be avoided even if the high temperature side end part 1H is subjected to high temperature heating. Furthermore, it is possible to avoid generation of sublimation and oxidation of a constituent element of the thermo-element 1 and prevent variation of an element and deterioration of characteristics.

IPC: H04N5/363
Filed: 1989-07-21
Abstract: PURPOSE:To prevent noise production at the correction of a picture element signal by applying transmission block control of a defective picture element to correct the defective picture to a correction circuit and transmission control of picture information in succession to the defective picture for a period other than a signal period sending the picture information in a picture element signal. CONSTITUTION:The correction circuit executing the correction of a picture element signal consists of a clamp circuit 1, a sample-and-hold circuit 2, gate circuits 3, 4 and a signal processing circuit 5. When a picture element represented in time series is sent sequentially to the sample-and-hold circuit 2, if a defective picture element takes place, the transmission block control to the sample-and-hold circuit 2 is applied for a period other than a signal period when picture information is sent and the transmission control of a succeeding picture element is applied for a period other than the succeeding signal period after the end of correction of a defective picture with one preceding picture element to the defective picture. Thus, no noise is superimposed at the correction of the picture element and an excellent correction output is obtained.

Abstract: PURPOSE:To obtain a charging signal transmitting circuit of a smal-lsize constitution where the generation of noise is reduced as much as possible, by controlling the direction and the value of the current on a telephone loop line by a  switching transistor. CONSTITUTION:When an input voltage of a waveform 2 is given to a filter circuit 1', an output voltage of a waveform 3 is obtained, and therfore, the collector current of a switching transistor TR1 is reduced gradually. When the collector current becomes zero, a relay An for polarity inversion is operated to invert the polarity if a voltage of a waveform 1 is given to the base of a TR2. Next, when a current of the waveform 3 is flowed to the base of the TR1, the collector current is increased gradually. Since the line current has a waveform 4 by this series of operations, the generation of noise for polarity inversion of the line current is reduced as much as possible.
