Title: Method for the automatic optimization of the recording bias
Inventor: WERNER MEDERER
IPC: H04N5/782
Filed: 1988-11-16
Granted: 1998-04-22
Abstract: The recording current necessary for recording a video signal is always to be optimally selected and adjusted with respect to the replay sensitivity, having regard to an audio signal already recorded on the same tracks and having regard to tolerances of the recording medium, of the heads and of the head amplifiers, by means of the novel method. For this purpose, the recording current is changed in steps during the recording of the video signal. After each change in the recording current for the video signal, a direct-voltage value is determined from the replay envelope curve of the audio signal as a measure of the replay amplitude of the audio signal. As soon as the direct-voltage value obtained from the replay envelope curve of the audio signal reaches a predetermined minimum value, the changing of the recording current for the recording of the video signal is ended and the last value of the recording current is stored for the following recording process. Recording systems in which video and audio signals are stored in tape layers of different depth. <IMAGE>

The circuit includes PWM generator (4) for generating rectangular wave with 1800 phase difference compared to rectified input signal, a DC-AC converter (5) for generating high frequency AC power, a driver (6) for controlling the DC-AC converter (5), a high-voltage generator (7) for generating high voltage from the high frequency AC power generated by the DC-AC converter, a voltage detector (8) for detecting voltage level of the high voltage generator (8), and a comparator (9) for generating error signal.

Abstract: A modular plastics panel for sheeting consists of an outer wall (2) forming a brim girth, a lot of horizontal and vertical reinforcing walls (4, 5) formed in the outer wall, a lot of bosses (b) and boss holes (7) formed on the crossing part for fastening the connection pins, and a lot of pin holes (8, 8') formed on both the outer wall and the reinforcing walls. The construction of sheeting is simply and easily finished by thrusting the connection pins into the pin holes and the boss holes. The connection pin having a head (13) for hammering is formed in a shape of a nail.

Title: Method and apparatus for tuning tv channel automatically
Inventor: CHOE SUNG-RYOL
IPC: H04N5/50

Granted: 1994-12-23
Abstract: This invent is about automatic channel conversion in a television receiver and about the formation of the system for automatic channel conversion, where the channel is changed automatically when detrimental program is received and then the changed channel returns to the original channel after finishing the program. The automatic channel conversion is fulfilled and completed through the demodulation of the received VPS data, inspection, channel assignment, and reversion to the original channel. The system is composed of two tunners, two VPS decorders, parts of the key input and preservation defining and storing the data that recognize programs, and two comparators. This method is useful even if the code user is absent and the set code is forgotten.
