Title: Detector of signal defect
Inventor: NISHIHARA MICHIHARU
IPC: G11B20/18
Filed: 1980-03-31
Abstract: PURPOSE:To simplify the constitution of circuit, by utilizing a retrigger-type one- shot multivibrator for the signal defect detecting means that uses the signal obtained through the FM signal demodulating system of a video disk player. CONSTITUTION:The FM signal detected by the pickup is amplified by a preamplifier and then supplied to the input terminal 1 as the signal SA. The signal SB shaped into a rectangular wave through a limiter 3 is obtained. One of these two signals is supplied to the full-wave rectifying circuit 5, and the other is delayed for a certain time through a phase shifter 4 to be turned into the signal SC. After this, the signal SD which responds to the FM signal is obtained through the circuit 5. The signal SD is integrated through a low pass filter 6 to obtain the demodulated output SE which is proportional to the density of pulse. The signal SD receives a discrimination through the signal defect detecting circuit (trigger enable one-shot multi) 10 whether it is within the prescribed frequency deviation.

Filed: 1980-04-07
Abstract: PURPOSE: To enhance the buffer capacity of a builder and reduce the treatment cost by neutralizing alkali hydroxide remaining in crystallized alkali aluminosilicate with acid or acidic salt followed by washing, filtration, etc.  
     CONSTITUTION: Zeolite is crystallized by a known method from a homogeneous composition composed of a silicic acid component, an alumina component, an alkali metal component and water within zeolite forming ranges. Alkali hydroxide remaining in the zeolite crystals is then neutralized with acid or its acidic salt under such conditions as make pH≥9.

Title: Controller for water level measurement
Inventor: FURUSATO AKARU
IPC: G05D9/12
Filed: 1981-03-27
Abstract: PURPOSE:To reduce the capacity of a tank, by controlling a water-sink level of an air bubbling tube to the tank upward and downward according to a preset program. CONSTITUTION:When the water level of a tank Q is increased by amount of water flowing, an air bubble tube LC is immersed with water, this back pressure operates with a liquid tank P, electrolyte W in a load cell LC is pushed up, and electrodes are immersed with a liquid W. Thus, a current flows between the electrodes and a motor IMC turns. When the flowing amount is increased more than the discharged amount, the water level of the tank Q is increased, the back pressure to the tank P is increased and the liquid W is pushed up, the number of revolutions of the IMC is increased to increase the discharge amount of pump. An upper and lower moving servo SM is operated with a program setter PT storing in advance the timing change of flowing amount to the tank Q to lower the tube LC and discharge is started from a point time earlier for the water increase. If the time zone of water increase elapses, the tube LC is elevated to a prescribed position similarly. Thus, pump delivery can be uniformed.

Title: Equipment fault signal transmission system
Inventor: SASAKI KATSUHIRO
IPC: H04L69/40
Filed: 1988-02-27
Abstract: PURPOSE:To improve transmission efficiency without necessitating a time slot for transmitting an equipment fault signal by transmitting the equipment fault signal by using a stack bit. CONSTITUTION:At a transmission side, a sending-end synchronous conversion circuit 103' outputs a staff information signal 21 when it is 'the existence of a stack'. A sending-end multiplex conversion circuit 104, controls the stack bit by the output signal of a fault detection circuit 102 and the stack information 21. In other words, the information of the presence/absence of an equipment fault is put on the stack bit. Meanwhile, at a reception side, a receiving-end separation conversion circuit 106, separates the stack bit when it is 'the existence of the stack', and sends it to a comparison decision circuit 204 as a fault detection signal 21. A decision circuit 204 compares it with reference decided in advance, then, decides the presence/absence of the equipment fault. Therefore, since it is not required to provide the time slot for transmitting the equipment fault signal separately, the transmission efficiency can be improved.
