Title: Transmission system with improved equalizer
Inventor: HO WAI UONRAMU
IPC: H03H17/00
Filed: 1994-06-23
Abstract: PURPOSE: To obtain a digital transmission system, in which the simplicity of execution of a forced 0 criterion and the behavior of convergence in the MMSE standards are combined by providing a sign filter and generating a prescribed correction signal. CONSTITUTION: An output of a transmitter 2 is fed to an equalizer 8 of a receiver 6 via a channel 4. An equalization filter 12 of the equalizer 8 extracts plural equalization signals from an input signal. An output signal of the filter 12 is given to a coupling means, consisting of multipliers 16, 18, 20 and an adder 14, from which a detection signal is obtained. The detector 10 extracts a sign from the detection signal, and a sign filter 34 decides a 2ns auxiliary signal. Multipliers 28, 30, 32 form a correction signal, depending on at least two consecutive detection signs for correcting a coefficient of the equalizer 8 with a 1st auxiliary signal equal to the detection signal and the 2nd auxiliary signal.  Integration devices 22, 24, 26 of an adaptive means 25 provide an output of a control signal to the multipliers 16, 18, 20 of the equalizer 8, to make a weight coefficient adaptive responding to the correction signal.

Title: Alarm device for gas leakage
Inventor: AKIYAMA SHIGEO
IPC: G01M3/20
Filed: 1980-11-21
Abstract: PURPOSE:To emit an adequate alarm despite presence of a false alarming gas by inputting the output signals from a detecting gas detecting part and a false alarming gas detecting part to logical circuits. CONSTITUTION:A gas detecting element 1a which is highly sensitive to gaseous buthane and gaseous methane and a gas detecting element 1b which is highly sensitive to steam and gaseous alcohol are connected respectively to resistances Ra, Rb, and the changes in the resistances of the gas detecting elements are converted to voltage changes Va, Vb. These voltages input to comparators 3, 4, 5. Since the reference voltage of the comparator 3 is set high, an output signal is generated only when the detecting gas of high concn. exists. The reference voltages V4, V5 of the comparators 4, 5 are set low, and generate outputs for detecting gas and false alarming gas of low concns. as well, but since the output of the comparator 5 is inverted by an inverter 7, an AND circuit 8 generates an output (d) only when the false alarming gas does not exist.

Abstract: PURPOSE:To reduce the number of elements of a circuit and to reduce the chip area when the circuit is integrated by utilizing the impedance of a first to fourth MOS transistors according to the change of an input waveform and obtaining an inverted waveform by letting the wave to have hysteresis from an inverter circuit. CONSTITUTION:When an input waveform IN is 5V, a first Tr7 is turned off, a second Tr8 is turned on, the output of an inverter 11 is made high level, a third Tr9 is turned off and a fourth Tr10 is turned on.

Thereafter, the drain voltage A of the Tr7 and 8 ascend with a gentle slope when the waveform IN descends toward an OV, an output waveform OUT changes from a low level to a high level. On the other hand, when the waveform IN is the OV, the impedance of the Tr7 and 9 becomes zero, the impedance of the Tr8 and 10 becomes infinite, and the waveform OUT changes from the high level to the low level. Therefore, the waveform OUT with hysteresis can be obtained.

Title: X-ray protection unit
Inventor: GOTOU TERUO
IPC: H04N3/18
Filed: 1978-12-30
Abstract: PURPOSE:To detect a high voltage and a beam current to prevent radiation of X- rays and reduce the number of parts to eliminate irregularity of an operation start voltage by providing a voltage detection winding on a fly-back transformer. CONSTITUTION:When a high voltage rises by any cause, the pulse voltage of detection winding T1 rises to raise the gate voltage of thyristor 5. When the voltage of thyristor 5 is lowered below the anode voltage, thyristor 5 becomes conductive. Therefore, horizontal oscillation of horizontal oscillator circuit 1 is stopped, and no high voltage is generated from high-voltae winding T2 of fly-back transformer T. The high voltage value which causes horizontal oscillation to stop can be set arbitrarily by selecting resistances R9 and R10. Meanwhile, when a beam current is increased, the voltage of the negative-side terminal of high-voltage winding T2 becomes negative, and the gate voltage of thyristor 5 is lowered through resistance R11  due to current feedback, and thyristor 5 is made conductive with a lower voltage,  and the operation start voltage to stop horizontal oscillation is lowered. By this constitution, the number of parts of the circuit can be reduced, and irregularity of the operation start voltage can be reduced.
