Title: Method for controlling concentration of dissolved oxygen
Inventor: HAYASHI HIDEYUKI
IPC: C02F3/12
Filed: 1982-05-21
Abstract: PURPOSE:To hold the concentration of residual substrates in a drained liquid after being aerated in a sewage system, by adjusting an amount of air to be supplied to an airflow regulator at the inflow side of an aeration tank for performing an activated sludge process in response to a DO value in a constant airflow part at the outflow side. CONSTITUTION:Sewage having flowed through an inflow opening 2 into an aeration tank 1 is biologically treated with activated sludge by O2 in air sprayed through a sparger pipe 7 connected to a variable speed blower 5 inside tanks 1a, 1b at an airflow regulating part 4. Thereafter, the sewage under the condition that its treatment is approximately completed is let flow into a tank 1c at a constant airflow part 8 to which a relatively small amount of O2 is supplied by a sparger pipe 11 connected to a constant speed blower 9. Consequently, by satisfactorily performing the treatment at the regulating part 4, the sludge flowing into the fixed part 8 is made into a stable endogeneous-respiring state, and a DO value is held at a preset one. However, when the DO value obtd. by a detecting part 12 is low, the flow rate of air from the blower 5 is increased by a regulator 13. When the sludge flows into the fixed part 8, it is adjusted to be the endogeneous-respiring state.

Title: Liquid balancing device
Inventor: TAKEKADO SHIGERU
IPC: F16F15/36
Filed: 1978-07-19
Abstract: PURPOSE:To get maximal liquid balancing effect, by fitting in a liquid-filled hollow ring a partition plate which creates two passages on the inner and outer wall sides, one being sufficiently larger than the other in flow resistance. CONSTITUTION:When this balancer is turned, the liquid filled in it is annularly excited and waves transferring inside the balancer are blocked by a partition plate 21 to prevent the balancer 11 from vibrating through self-excitation caused by the waves. When the balancer is quickly turned, the liquid 24 gathers around the partition plate 21 because of inertia to lose the balance, but the liquid passes through the first passage 22 which is large in area and small in flow resistance, thus recovering the normal revolution without losing the balance. The liquid pressure is higher in 24'' than in 29'', but this pressure difference makes the liquid pass through the second passage 23, which makes the pressure equalized on both sides of the partition plate 21 to regain the balance.

Title: Joint part for pipes
Inventor: OHIRA TADAYOSHI
IPC: F16L37/04
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To easily perform wiring without forming a stepped portion on an inner surface of the connection part of a pipe by arranging a rubber tube in a gap for eliminating axial displacement of the pipe inserted into a socket and prevent breakage of the pipe while eliminating displacement of the ends of the pipes when external force is applied after connection of the pipes such as earthquake. SOLUTION: Plural circumferential grooves 13a are formed on an outer surface of a rubber tube 13 to show a corrugated section like bellows. The stepped portions are eliminated by one end of a right side pipe 10 opposed to a reception port 11 at its inner side and a rubber tube 12 having an inner diameter equal to that of the left side pipe 10 wiring of an electric cable is easily performed. When axially compressive force is applied to the rubber tube 13, the axial displacement of the pipe 10 due to the compressive force is eliminated by compressive deformation of the rubber tube 13. A large part of the displacement is eliminated by a thin portion composing a bottom of the circumferential groove 13 being bent to form pleats. The axial length of the thin portion is short, so that no backing occurs.

Abstract: PURPOSE:To prevent damage caused by heating of parts by returning a processor to an initial state in the vicinity of an abnormality detecting temperature at the time of a normal control of the processor by a hardware circuit, when the processor runs away and a fixing heater lamp is lighted continuously. CONSTITUTION:When a CPU 200 runs away due to a noise, etc., and an output port b1 is latched to a low level, a fixing heater lamp 20 is left in lighting as it is, but when its temperature becomes the vicinity of T2 being higher than a fixation control temperature T1, the voltage of a detecting signal A of a thermistor 16 becomes lower than a voltage B applied to an inversion input terminal of a comparator 230. As a result, the output signal of the comparator 230, namely, the input signal C of an AND circuit 210 becomes a low level, and the output signal of the AND circuit 210 becomes a low level. In such a way, the CPU 200 becomes a reset state, the output port b1 is changed to a high level and an SSR 220 becomes an OFF state, and the fixing heater lamp 20 is turned off.

Abstract: PURPOSE:To perform the processing of necessary data within a short time by providing a narrow-band filter on the light path connecting an interference mechanism and a detector. CONSTITUTION:A narrow-band filter 13 is provided on the light path connecting the interference mechanism 6 and detector 8 of this apparatus.

For example, when (n) sample waves are taken in a band and the cosine wave corresponding thereto is expressed, (n) vectors are mutually linear independence and, therefore, the measured interferogram can be expressed by n-dimensional linear connection. By this method, necessary data can be processed within a short time.

Title: Automatic white-balance regulator of color television camera
Inventor: NISHIKAWA SHIYOUJI
IPC: H04N9/04
Filed: 1980-06-27
Abstract: PURPOSE:To operate in the fully automatic white balanced state without pushing any switch by composing the titled regulator of a device which detects the color temperature of illumination and a device which adjusts white balance automatically. CONSTITUTION:A condenser 21 condenses the external light of a visual field including an object, a color temperature detector 22 detects the color temperature of the condensed light, and a color-temperature fluctuation detector 23 discriminates whether the detected color temperature fluctuates to a prescribed extent or more. When the discrimination results show that the fluctuation exceeds the prescribed extent, a gate signal generator 24 generates a gate signal for turning on gate circuits 19 and 20. Consequently, two negative feedback loops of gain control circuit 4 and 5, detectors 6 and 7, subtracters 8 and 9, smoothing circuits 10 and 11, gate circuits 19 and 20, and storing circuits 14 and 15 are put in operation so that the outputs of the subtracters 8 and 9 are 0s. Consequently, if the color temperature of an object fluctuates during image pickup operation, the circuits 19 and 20 are turned on automatically to operate the function of adjusting white balance, thereby performing the image pickup operation in the white-balanced state.
