Title: Drive device for thermodynamic reciprocating engine
Inventor: MUROZONO KOUJI
IPC: F02G1/053
Filed: 1982-10-18
Abstract: PURPOSE:To simplify the structure of an engine and as well to make the engine compact and lightweight, by providing such an arrangement that piston members are reciprocated with a phase difference within a crank operating space which is maintained at a pressure lower than the lowest pressure in either one of high and low temperature working spaces. CONSTITUTION:A displacer 1 is coupled with a crank shaft 13 in such a way that the projection 19 of a displacer rod 11 is abutted against the cam surface 21 of an eccentric cam part 20 formed on the crank shaft 13, and a coming-off preventing wall part 22 prevents the above-mentioned projection 19 from coming off the cam surface 21. A crank chamber space 23 is maintained always at a pressure lower than the lowest pressure of a high temperature side working space 6 so that downward urging force is always exerted to a piston 2, and therefore, there is no need to provide a projection to a piston rod 24, and a coming-off preventing wall part to an eccentric cam part 25. Further, there is no need to use a connecting rod for driving the displacer 1 and the piston 2. Accordingly, the structure of the engine is simplified and as well the structure of the engine may be made compact and lightweight.

Title: Compensation system for distortion in base band
Inventor: NAKAMURA TADASHI
IPC: H04L25/02
Filed: 1993-07-26
Abstract: PURPOSE:To obtain an output signal which operates over a wide dynamic range of input and has small intermodulation distortion. CONSTITUTION:A coefficient k3 which determines (3/4Nk3B<2>cos ((2f2)t+(2thetab-thetaa))) as the frequency (2f2-f1) of a tertiary intermodulation component IM3 is determined 13 according to the values A and B and thetaea and thetab of received signals of two frequencies f1 and f2 high level. The (2f2-f1) of estimated intermodulation component distortion IM3 to be generated is calculated 11, and the calculated intermodulation distortion (IM3) is subtracted 12 from a received signal consisting of a received signal D of the same frequency (2f2-f1) and distortion IM3. The received signal having small distortion component IM3 obtained by the subtraction is demodulated by a demodulator DEM, and the interference component IM3 is removed from the received signal consisting of the signal D of frequency 2f2-f1 and distortion component IM3 under loop control which changes the coefficient k3 determining the intermodulation component so as to minimize the code error rate of the demodulated data. Then only the signal D of frequency (2f2-f1) is outputted.

Title: Manufacture of piezoelectric ceramic oscillating element
Inventor: MATSUI KOICHI
IPC: H03H3/02
Filed: 1989-07-14
Abstract: PURPOSE:To obtain a good spurious characteristic by providing a step where the relation between principal surface dimensions and thickness dimensions of a piezoelectric ceramic body is so set that perpendicular longitudinal oscillation and spreading harmonic oscillation overlap in the spurious range. CONSTITUTION:When principal surface dimensions AXA of a piezoelectric ceramic body 2 are fixed to, for example, 4.70mmX4.70mm, a good spurious characteristic is obtained with thickness dimensions (t) approximating 450mum. When principal surface dimensions AXA of the piezoelectric ceramic body 2 are fixed, the spurious characteristic is changed by the change of thickness dimensions (t). Perpendicular longitudinal oscillation of an angular piezoelectric ceramic oscillating element 1 consists of oscillation of various modes. These modes include the harmonic mode of spreading oscillation. Thus, perpendicular longitudinal oscillation and spreading harmonic oscillation overlap in the spurious range when the relation between thickness dimensions (t) and principal surface dimensions A of the piezoelectric ceramic body 2 is properly set.
