Title: Modulator-demodulator system and its circuit
Inventor: KURODA KIYOSHI
IPC: F02B75/02
Filed: 1987-12-09
Abstract: PURPOSE:To improve the data modulation/demodulation efficiency and to reduce the transmission time by modulating a peak data synchronously with 1/2 cycle of a carrier frequency. CONSTITUTION:A signal having a peak proportional directly to a 4-bit data outputted from a memory Memory is formed. Let the frequency of the carrier be 2kHz, then it is required to read out a data from the memory from 1/2 cycle each, the original frequency of the carrier from an oscillation circuit OSC is to be 8kHz, then the frequency is subject to 1/2 frequency division and the result is used as a clock of an address counter ADR-COUNT for memory readout. Furthermore, the frequency is subject to further 1/2 frequency division to form a 2kHz square wave and converted into a sinusoidal wave by a 2kHz LC resonance circuit. The original 8kHz oscillation circuit is a CR oscillation circuit but not so much accuracy is required by employing a PLL circuit for the demodulation circuit. Thus, the data transmission with high efficiency is attained.

IPC: G06K7/10
Filed: 1992-10-26
Abstract: PURPOSE:To recognize patterns from the waveform shape without binarizing a signal waveform reading a bar code symbol by an optical means.

Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To improve tracking follow-up performance by setting an angle made between a center of gravity of a disc and a track center of gravity with respect to a disk center such that a tracking driving current value is minimum at a desired rotational speed.
