Abstract: PURPOSE:To make it possible to position and support the regenerator consisting of a compressed body simply and securely by its own tensile force, relating to a Stirling engine in which the compression space and expansion space inside the cylinder are connected to each other with at least a regenerator interposed therebetween, by forming the regenerator out of a compressed molding of metal mesh. CONSTITUTION:Inside the cylinder of a Stirling engine a compression space and an expansion space separated by a piston are connected to each other with at least a regenerator 6 interposed therebetween. In this instance the regenerator 6 is formed by laying compressed bodies 13 of metal mesh one over another, which are, for example, compressed bodies molded by compression of a woollike knitted work of fine metal wire. Each of the compressed bodies 13 is formed in the shape of a cylindrical body with a diameter corresponding to the bore of a block 8 designed to hold a regenerator 6, etc., shaped as a cartridge; the diameter of each compressed body is made a slightly larger than the bore so as to make the compressed body produce tensile force of its own.

Title: Color television receiver
Inventor: NISHIDE TAKUYA
IPC: H04N9/44
Filed: 1978-06-13
Abstract: PURPOSE: To increase the stability of operation by stopping the operation of the correction circuit in the weak field where the color correction circuit does not operate and then giving the hysteresis characteristics to secure the restart of operation when the input signal exceeds a fixed level.  
     CONSTITUTION: For the synchronous signals, the waveheight value is increased by the differential circuit comprising capacitor 4 and resistance 2 in case the normal VIR signal exists. But the output of flip-flop 13 features a low level when the input signal becomes faint. Thus output -Q features a high level. As a result, the synchronous signal of the input is integrated, and the waveheight of the waveform supplied to pulse amplifier 6 is reduced forcedly. During this period, output -Q of the flip-flop is kept at a high level. In order to inverse the flip-flop, the sufficiently intensive signals must be supplied including those in which the waveheight of the input is reduced forcedly.

Title: Up rate converter
Inventor: NODA SHIGETOSHI
IPC: H04N7/01
Filed: 1991-04-04
Abstract: PURPOSE:To prevent the brightness of an output picture from being uneven by performing up rate conversion of an input video signal based on filtering coefficients having filter characteristics resembling one another. CONSTITUTION:A coefficient generating means 1 generates plural filtering coefficient strings which have filter characteristics different from one another and are circulated in accordance with the up rate conversion ratio. Coefficient selecting means 9A to 9E have optimum filter characteristics cut off by Nyquist frequencies in accordance with the selected up-rate conversion ratio. Filtering coefficients having filter characteristics resembling one another are selected from plural filtering coefficient strings to generate another filtering coefficient string. The up-rate conversion of the input video signal is performed based on this filtering coefficient string. Thus, the variance of the frequency characteristic for individual output picture data is reduced to reduce the periodical unevenness of brightness.
