Abstract: PURPOSE: To raise the yield of a mold or a reaction product, by increasing and decreasing temporarily a fixed quantity of oxygen transfer conditions except the operation quantity for controlling the concentration of dissolved oxygen, and carrying out the control of the fittest feed rate of substrate depending upon the change in the concentration of dissolved oxygen.  
     CONSTITUTION: In order to know the consumption rate of oxygen which is in proportional relation with the activity and the propagation amount of a mold, the number of revolutions of an agitating blade is increased temporarily by a fixed quantity Δc rpm for the measuring time of bh in a period of the measuring interval of ah as shown in the fig. 2. By the increase in the number of revolutions of an agitating blade, the concentration of dissolved oxygen (DO) is increased by Δd, Δd'mg/l as shown in the fig. 3 (the rate of oxygen consumption is changed with the time ellapsed). The feed rate of substrate is calculated based on the changed DO value, and the feed rate of substrate is controlled depending upon the calculated value.

Title: Air flow deflecting device of air conditioning duct
Inventor: ITO YOSHITAKA
IPC: F24F13/072
Filed: 1986-03-31
Abstract: PURPOSE:To gradually narrow the opening area and to hold constant the quantities of air blown through a blow-off port by equalizing an imaginary passage divided at the branch flow portions of respective fins, and guiding the air quantity introduced through a maximum flow speed passage of opening area between guide portions of fins to a small blow-off port of the maximum opening area. CONSTITUTION:A thin and long air blow-off duct 1' for blowing off perpendicularly an airstream A within a duct is formed sidewise at the tip end of the commonly used duct having a square section. The air stream within the duct flows in such a state wherein it assumes a maximum value S1 at the central portion, and is lowered to values S2 and S3 as it draws near to the wall surface on both sides. Even in respective flowpaths of the same section, divided between branched flow portions of respective fins, the flow speed becomes W1<W2< W3>W4>W5. Since a blow-off opening area L3 taken in through a flowpath W3 of the maximum flow speed is maximum, an airstream blown off from an opening area L3 is diffused and is lowered of its flow speed, whereas since blow-off opening areas L1 and L5 taken in from minimum flow speeds W1 and W5 are minimum, airstreams blown off through L1 and L5 are not diffused so much with the result that blown airstreams become equalized.

Filed: 1979-06-06
Abstract: PURPOSE: To prevent the generation of white smoke and offensive odor due to the discharge of unburned gas by a method wherein the electrification to an oscillating circuit driving an electromagnetic pump is short-circuited simultaneously with the stoppage of supply from a power source at the time of stoppage of the device and thereby the further supply of oil is stopped.  
     CONSTITUTION: When a power-source switch 1a is opened to stop combustion, a control circuit 3 stops working and a contact point 4 for control is switched on to the side of a constantly-closed terminal 4a, thereby the electrification on to the side of the oscillating circuit 16 of an electromagnetic pump 17 being cut. Simultaneously, the resistances 13 and 14 on a transistor-switching circuit for discharge are electrified and the voltage is generated in the base of a transistor 19, thereby the transistor 19 being turned on. In this way, the resistances 11 and 12 giving output to the oscillating circuit 16 of the electromagnetic pump 17 are short-circuited to each other by the transistor 19 and thus the pump 17 is stopped immediately. Accordingly, further oil supply is also stopped.
