Title: Thrmoelectric transducer
Inventor: KONDO AKIRA
IPC: H01L35/00
Filed: 1993-09-20
Abstract: PURPOSE:To provide a thermoelectric transducer of improved conversion efficiency by a combination of a p-type semiconductor and an n-type semiconductor, which comprise porous silicon carbide having porosities within a specific range. CONSTITUTION:A thermoelectric transducer is the combination of a p-type semiconductor and an n-type semiconductor. The p-type semiconductor is silicon carbide solid solution which contains a group III element such as boron or aluminum as an acceptor, and the n-type semicondutor is silicon carbide solid solution which contains a group V element such as phosphorus or nitrogen as a donor. The p-type semiconductor and the n-type semiconductor are made of porous silicon carbide whose porosity is within a range of 65-95%. If the porosity of the silicon carbide is less than 65%, a thermal conductivity is high and the performance of the thermoelectric transducer is degraded. If the porosity is larger than 95%, the mechanical strength is degraded and the silicon carbide becomes fragile, so that it is easy to be damaged by a thermal stress. With this constitution, the heat-resistant properties and the chemical stability can be improved and, further, the thermoelectric conversion efficiency can be improved.

Title: Eliminating circuit for msk signal component of receiver output
Inventor: TSURUTA MITSUGI
IPC: H04B1/16
Filed: 1991-10-04
Abstract: PURPOSE:To eliminate the MSK signal component out of the sound output even with temporary break of the received signal by cutting off mixture output of the sound signal and the undesired MSK signal component and then transmitting only the sound signal through a filter. CONSTITUTION:A 2nd analog switch SW23 is turned on by the inverted output H of the MSK detection output L of a data modem DEM and outputs only the sound output, i.e., the output of a filter 2 which eliminates the MSK signal component out of the mixture output of the MSK signal and the sound signal of the FM demodulation output of a receiver RX serving as the output of a delay circuit 1. Meanwhile a 1st analog switch SW110 is turned off with the output L and the pass is cut off for the mixture output of the sound signal of the FM modulation output and the MSK signal. In such a constitution, the sound output is never interrupted even though the receiving signal is temporarily cut due to the fluctuation of a receiving field or the delay time is caused to an FM modulation part and the detection of the MSK signal of the modem. Then the talking using the sound signals can be smoothly carried out.

Abstract: PURPOSE:To attain high resolution without picture flicker without causing a color false signal by providing a cyclic transfer stage able to store signal charges by two fields and a swing means to the device so as to extract two color signals from a same picture element position. CONSTITUTION:A color filter array for 2 picture element period in the horizontal direction is in use and the relative position between an optical image and a solid-state image pickup element is swung by one picture element in the horizontal direction and the signal charge by two fields obtained at relative positions A, B is respectively transferred to cyclic transfer stages 40,40,... and the charge of each of the positions A, B is transferred horizontally alternately to two horizontal transfer stages 42, 43 and outputted to a line. Thus, two color signals are extracted from a same picture element position as to the horizontal direction. Thus, even when a contrast pattern of a same period as the period of the color arrangement of the color filter array is picked up, the production of a color false signal is considerably reduced and high resolution is processed.

IPC: G11B15/087
Filed: 1989-10-03
Abstract: PURPOSE:To set the write position of a lead-in area at the same position by setting a tape recorder in a tape feeding state when a top sensor detects a leader tape and stopping the traveling of the tape when it detects a magnetic main body. CONSTITUTION:When rewinding instruction is given from a input means in order to perform the write in the lead-in area, a system controller controls a mechanical block so as to rewind the tape. When the top sensor detects the leader tape, the traveling of the tape is stopped. When a write processing instruc tion is given from the input means, the controller controls the block so as to start the feeding of the tape and stop it at the time of detecting the magnetic body of the tape. Then, the controller allows a signal processing means to generate silence to obtain a recording mode, and the block is also switched to the recording mode and the write is performed in the lead-in area. Thus, the top of the tape is detected at the same position and the write position is set at the same position even though rewrite is performed in the lead-in area plural times.
