Granted: 1990-07-31
Abstract: A instrument for detetcing stray metal in e.g. ham, sausage etc. The magnetic field is detected by coils which generate induced voltages abd the difference between the induced voltages is applied to a tuning and phase-shift circuit. An output signal having a phase, generated from the tuning and phase-shift circuit, is detected and the peak level of the detected output signal is held in a peak hold and comparing circuit. A number of the peak levels are stored in a memory circuit and are processed by a CPU to determine the preferred phase of the output signal. The tuning and phase-shift circuit is so switched as to apply the preferred phase to the output signal.

Abstract: The method comprises the first step for converting a system into sound field effect modes, the second step for conforming a key input to set an echo or a suround mode and transfering a select signal of a sound field effect mode to a pack data area of digital signal processor (5), the third step for modulating on time to record a select signal of a sound field effect mode in a subcode area, the forth step for amplifying a modulated sound field mode select signal and recording it in the subcode area of a tape through a head, the fifth step for detecting a sound field effect mode select signal recorded in the subcode area in replay mode and transferring it to a digital signal processor (7) for a sound field, and the sixth step for producing a sound field mode sound corresponding to the transferred sound field effect mode select signal and outputting it together with a original reproducing sound through a signal converting process.

Title: Remote control system for public telephone
Inventor: LEE HAE-DO
IPC: G06F13/00
Filed: 1992-02-14
Granted: 1994-10-13
Abstract: The remote control system adds telephone use charges in this system using a public telephone line so that the charge adding time and human efforts can be reduced remarkably. This system includes a slave system and a main computer system, the slave system formed by a ring signal sensor, one-chip processor unit, a switch, a relay, and one-chip MODEM(modulator-demodulator) unit connected between the one-chip processor unit and the relay.
