Title: Piezoelectric displacing device
Inventor: MOMOKI MOTOYASU
IPC: H02N2/00
Filed: 1983-11-18
Abstract: PURPOSE:To displace a magnetic head or an optical head in multiple directions by simultaneously applying a voltage to several divided laminated ceramic units. CONSTITUTION:A piezoelectric ceramic element is formed in a lamininated hollow cylindrical structure, which is equally divided into four segments (36, 37, 38, 39).

Filed: 1992-07-24
Abstract: PURPOSE:To provide phase data with simple configuration by discriminating a phase range by using a triangular function. CONSTITUTION:Concerning this digital phase discriminating method used for a signal processing method constituted for obtaining a phase while using inverse triangular relation, the phase is specified corresponding to the magnitude relation among the sign of a triangular function sintheta, the sign of costheta and the amplitude absolute value of sintheta and costheta. In the case of discriminating the table area of tan<-1>theta and cos<-1>theta, for example, input digital data sin +1 to +255 of 8 bits are calculated by an arithmetic operation circuit 21, converted to the 8-bit data of -127 to +127 and inputted to a Hilbert transformer 22, and 90 deg. phase shift data costheta -127 to +127 are obtained. The positive/negative sign of sintheta (costheta) is obtained from these data. On the other hand, since the difference of low-order 7-bit data of sintheta and costheta are obtained by an arithmetic circuit 23, the magnitude relation between the absolute values of sintheta and costheta is obtained. The outputs of these arithmetic circuits are inputted to an arithmetic circuit 27, and an area discriminating output A is obtained.
