IPC: H03M7/32
Filed: 1984-10-09
Abstract: PURPOSE:To output sampling data while being compressed into a very less bit number by converting the sampling data into residual data and converting it into residual difference data for output. CONSTITUTION:A waveform shown in figure A is taken as a music signal F(t) of a natural musical instrument and a time (00) is taken as a music generating start time. In this case, a difference between the residual data D(K)1 at a sample point time t(K)1 of the 1st period T1 and a residual data D(K)2 at a sample point time t(K)2 corresponding to the time t(K)1 of the 2nd period T2 is very slight. Then a residual data D(n) at a sample point before one period is subtracted from the calculated residual data D(n), the result of subtraction, that is, a residual difference data E(n) is written in a memory M. The residual difference data E(n) is far smaller than the residual data D(n), and then the data amount to be stored in the memory M is decreased far less than that of a conventional circuit.

Title: Laser scanner
Inventor: NISHI KAZUO
IPC: G02B5/32
Filed: 1981-12-29
Abstract: PURPOSE:To increase the number of scanning lines equivalently by varying the focusing position of a hologram lens in such a way that scanning lines on a surface to be scanned at some rotation position of laser luminous flux do not overlap with scanning lines axially symmetrical about the rotation position. CONSTITUTION:Laser luminous flux 12 incident to a hologram 4 arranged on a hologram disk 3 in high-speed rotation is scanned over deflection to form scanning lines as many as hologram lenses 4 on the scanned surface 15 at intervals P as shown by solid lines. Simultaneously, the laser luminous flux 12 is rotated coaxially with the hologram disk 3 at a low speed in the circumferential direction of the disk 3 to rotate the scanning lines. Then, the scanning lines (solid line) on the scanned surface at some rotation positions of the laser luminous flux never overlap with scanning lines (broken line) at positions axially symmetrical to the rotation positions, so the number of scanning lines is doubled equivalently and an actual scanning pattern is obtained by rotating the scanning pattern around a point O, thereby increasing the number of scanning lines equivalently.
