Title: Water treatment device
Inventor: HASEGAWA SHIYOU
IPC: B01D29/62
Filed: 1982-11-22
Abstract: PURPOSE:To provide a water treatment device which enables water treatment with less energy by combining a biological filter device of an upward current system in particular and a gravity filter device of a downward current system. CONSTITUTION:The raw water which is supplied 6 into the bottom of a biological filter device 2 and is blown with air through an air diffusion pipe 8 is removed of a BOD component and SS by the biological film formed on the surface of filter media while said water flows upward in a filter layer 7. On the other hand, the raw water is maintained in an aerobic state by dissolved oxygen to activate the effect of the biological film thereby improving the efficiency for removing the BOD component. The treated water obtd. in such a way is transferred from a water drawing trough 4 by gravity into the liquid feed trough 11 of a gravity filter device 3 in a succeeding stage. The same device as a known gravity filter device is usable for said device 3; for example, the filter layer consisting of sand stacked on a backing layer of gravel or the like is used for the layer 12. The treated water produced in the device 2 is removed of SS and is thus cleaned while it flows downward in the layer 12. The clean water is removed from a take-out pipe 13 to the outside and is stored, for example, in a storage tank.

Abstract: PURPOSE:To provide a mechanism which can selectively lock a lens barrel at two positions, i.e., the rotational center of the yawing/pitching direction of the lens barrel and an optional position under rotation. CONSTITUTION:Two lock pins 25 are provided to a lens barrel 2 which is supported to be freely rotated in the yawing/pitching direction to a housing 1.

Title: Centralized monitor system of gas leakage by power-line carrier
Inventor: HINO KASHIRO
IPC: G08B21/00
Filed: 1984-09-28
Abstract: PURPOSE:To centralize and monitor always states of individual alarm devices in one place without providing a considerable number of leased lines by using a power-line carrier means to transmit output signals of gas leakage alarm devices, which incorporate sensors which detect coal gas, to a remote place. CONSTITUTION:A signal wave f1 is modulated by a carrier wave f0 in case of emergency and a signal wave f1' is modulated by the carrier wave f0 in case of normalcy in a slave device A in accordance with the monitor state of a gas leakage alarm device 9, and these waves are charged to a power line 15, but there are no signals on the power line in case of abnormality. A master device B in the monitor side receives the signal transmitted to the power line and selects the carrier wave by a detecting part 10 and a fundamental wave f0 tuning amplifying part 11. The signal wave f1 and the signal wave f1' are demodulated by a signal wave f1 demodulating part 12 and a signal wave f1' demodulating part 12'. A signal wave discrimination control part 13 discriminates the emergency state, the normal state,or the abnormal state and sends a signal corresponding to the discriminated state to a succeeding display alarm device 14 to display this state. When many gas leakage alarm devices 9 are provided, similar slave devices are installed to transmit monitor states to the power line. In this case, such frequencies are used that signal waves of individual slave devices do not interfere with one another.

Title: Automatic power controller of amplifier
Inventor: NAKAMURA SUSUMU
IPC: H03G3/30
Filed: 1982-11-19
Abstract: PURPOSE:To prevent the transmission output from being excessive by limiting an input voltage when an automatic power control loop is opened. CONSTITUTION:When an automatic control loop is opened, a differential amplifier 9 is controlled so that its output voltage is kept to a voltage having a prescribed deviation to the voltage of a fixed bias power supply 12. The deviation between this fixed bias voltage and an output voltage of the differential amplifier 9 is decided by the voltage dividing ratio of voltage dividers 17, 18. The ratio is set so as to be larger than the output change of the differential amplifier 9 until the automatic control loop is closed and its direction is to increase the attenuation of a voltage controlled attenuator 2. In closing the automatic control loop, the transmission output is decreased once and then reaches an objective value.

Abstract: PURPOSE: To produce high purity nitrogen containing a minimum amount of excess hydrogen by using an improved membrane/deoxo controlling system and method in which feed-forward control is combined with feed-back control for quick response to an operation condition. CONSTITUTION: Supply air is fed to a non-cryogenic air separation system 2 through an inlet line 1.

A computer control system 9 calculates a hydrogen flow rate and controls a hydrogen-flow control valve 16 by an output signal 17 from an orifice flow meter measuring means 15, and maintains the hydrogen flow rate equivalent to a hydrogen flow rate theoretically required for a reaction with residual oxygen in the crude nitrogen stream sent from the non-cryogenic air separation system 2. The crude nitrogen from a line 3 is well mixed with hydrogen from a line 14 in a mixing chamber 18, then sent to a vulcanizing deoxo vessel 20 through a line 19. The purified gaseous nitrogen stream is recovered as a high purity nitrogen product substantially free from oxygen.
