摘要： PURPOSE:To stabilize a recording wavelength and to increase recording capacity by recording wavelength checking information by means of a reference wavelength and controlling the oscillation frequency of a laser beam to be emitted at the time of recording/reproducing so as to allow it to coincide with the reference wavelength. CONSTITUTION:A light emitting spectrum of a semiconductor laser goes to an uncontinuous longitudinal mode wavelength with a fixed interval in accordance with the increment of an injection current. Recording, reproducing and tracking are executed in accordance with the uncontinuous wavelength. At that time, 8-bit wavelength checking information is recorded in a header area of each sector on a track by means of the recording/reproducing wavelength. At the time of recording/reproducing, a wavelength pattern detecting/collating circuit 71 compares inputs lambda1-lambda8 with the wavelength checking information based upon the reference frequency recorded in a ROM 72. The output of the circuit 71 controls the injection current, i.e. the wavelength, of the semiconductor laser through an injection current pattern generating circuit 73 and a D/A converter 74. Consequently, the wavelength to be used for multiplex recording can be stabilized and the storage capacity of information can be increased.

摘要： PURPOSE:To prevent disabled reproduction of all signals over one record length by recording and reproducing a time series signal as a position series signal while fixing the wavelength. CONSTITUTION:Suppose that a light spot radiated through an objective lens 14 is placed, e.g., at a point C of a header 19 of a radial position 22, since the medium 18 is turned in the direction of arrow R, the light spot is relatively scanned along the radial position 22 sequentially as point C point D point E point F. In this case, the wavelength of the light source is not scanned in the direction of the wavelength but fixed to the specific wavelength such as lambda1 or lambda2 to apply recording/reproduction. That is, even when a defect is caused to a storage element on a medium and reproduction is disabled, the defect is sufficiently recovered by the known error correction method.

摘要： PURPOSE: To prevent the hindrance of the activity of anaerobes and to reduce the size of a titled device, by using the digester gas generated from a digestion tank as a gas for floating in a sludge concentrating device of a sludge digestion device consisting of the sludge concentrating device and the digestion tank.
CONSTITUTION: Raw sludge is introduced by a pump 15a through an introducing pipeline 5 into a floatation tank 17. On the other hand, the pressurized water dissolved under pressure with the digester gas pressurized with a compressor 28 in a pressurization tank 23 is introduced through an introducing pipeline 24 into the tank 17, where the pressure is released therefrom to develop fine foam. The foam sticks on the raw sludge and concentrates and floats the sludge. The floating sludge is put with a skimmer 21 into a storage chamber 20 for concn. sludge, from which the sludge is discharged by a pump 15b into a digestion tank 12. The liquid separated by flotation is discharged through a pipeline 7 and the waste gas is released with a blower 27 from a gas release pipeline 26 connected to a top plate 22.

摘要： PURPOSE: To enable the uniform desorption of ozone with time and the stable distribution of ozone, by carrying out the vacuum desorption intermittently during the desorption period, and raising the temperature of the ozone adsorbent in the adsorption column to a specific level during the interruption period of the vacuum desorpiton.
CONSTITUTION: Oxygen is supplied from the oxygen source 2 constantly at a specific pressure to the circulation system consisting of the circulation blower 3, the ozonizer 1, and the ozone adsorption column 4, and the generated ozone is adsorbed to the adsorbent in the column 4 cooled by the cooling source 5. When the amount of adsorbed ozone reaches the saturation level of the adsorbent, the operation is changed to the desorption stage. The change-over valves 8-1, 8-2, 8-3 and 8-4 are closed, the change- over valve 8-7 is opened, and the water jet ejector 7 is operated to such the ozone from the column and produce concentrated ozonized water. When the pressure in the column 4 is decreased by the progress of desorption, the valve 8-7 is closed by the signal of the pressure sensor 9, and the valves 8-5 and 8-6 are opened to heat the adsorbent by the heat source 6. When the inner pressure of the column reaches a specific level, the valve 8-7 is opened again by the signal of the sensor 9. The above operations are repeated.

摘要： PURPOSE:To stably hold the pH value of purified water, by introducing the consumption coefficient of hydrogencarbonic ion in water to accurately obtain pH of the purified water, and feeding back actually-measured Ph according to PID calculation. CONSTITUTION:Raw water gathered in a water purifying plant is disinfected by the preinjection of chlorine in a water-intake well 1, and then a flocculant 11 is further injected to remove suspended matter. Thereafter, the water is let flow through a mixing pool 2, a flocculating pool 3 and a precipitating pool 4 to remove most of turbid substance. The purified water is sampled from the vicinity 12 of the outlet of the precipitating pool and measured by an on-line pH meter 13. The deviation of the actually-measured pH value (PV) from a preset pH value is calculated (EV) by an arithmetic unit 14, and the injection ratio of an alkali is set in response to said EV. The set injection ratio of an alkali is converted into an injection amount according to the flow amount of intake water and utilized for adjusting the opening ratio of the valve of an alkali injector 10 or the like

摘要： PURPOSE:To make good use of heat retained in sludge for enhancing thermal economy, in the system for digesting sewage sludge or the like, by performing heat-exchange using a heat pump between withdrawn sludge and charged sludge. CONSTITUTION:Withdrawn sludge from a secondary digesting cell 2 is carried through a withdrawing pipe line 6, heat-exchanged by the evaporator 14 of a heat pump 13 and the discharged outside the system. Charged sludge is introduced through the pipe line 6 into a condenser 15, heated by the action of the heat pump 13 and carried through a pipe line 8 to a primary digesting cell 1. On this occasion, valves 18a, 18d are opened, while valves 18b, 18c are closed. After the operation of charging and withdrawing sludge is completed, the valves 18a, 18d are closed, the valves 18b, 18c are opened, so that sludge in the primary digesting cell 1 is cyclically heated. A heat medium such as secondarily- purified water or hot water is hence introduced from the outside through a pipe line 19 into the evaporator 14.
