Title: Input signal interruption detecting system
Inventor: SUZUKI KAZUHIRO
IPC: H04L25/02
Filed: 1988-06-16
Abstract: PURPOSE:To attain the stable detection of input signal interruption even if a mark rate of an input signal is lowered by providing a filter passing through a prescribed frequency being the result of frequency division of the frequency of an input signal to the pre-stage of an input signal interruption detection circuit. CONSTITUTION:A filter 200 passing through the frequency being the result of frequency division of the frequency of the input signal is provided to the pre-stage of an input signal interruption detection circuit. Thus, a clock having a frequency of, e.g., 1/n of the input signal frequency is obtained. The output is fed to the input signal interruption detection circuit 600, where it is compared with, e.g., a reference voltage to discriminate the presence of the input signal. In this case, even if the mark rate of the input signal is lowered, since the frequency is divided into 1/n, a change in the output voltage of the filter 200 applied to the input signal interruption detection circuit 600 is less. Thus, the stable detection of input signal interruption is attained.

Abstract: PURPOSE:To make heating uniform with a cheap constitution by integrally molding a substrate covered with a specific heating material cont. ceramics and making the substrate uniformly increase its temperature and generate heat even if it is irradiated by non-uniform microwaves. CONSTITUTION:The heating element is constituted of a substrate 1 and SiC cont. ceramics 3 which covers the substrate 1 and is integrally molded. The substrate 1 is a metal plate with a high thermal conductivity having many through holes 1a.

Abstract: PURPOSE:To increase maximum transmission distance without causing erroneous reception even when guard time is shortened, by short-circuiting, for example, a reception winding except the transmission-line side winding of a transformer through a switch in a main transmission line interface circuit of a main line. CONSTITUTION:A transmission line interface circuit has a transformer 3 which has windings 5, 6, and 7 connected to a transmitting circuit and a receiving circuit, and a switch 13 for a winding, e.g. winding 6 connected to the transmitting or receiving circuit for a certain time after the transmission of the transmitting circuit.
