Title: Bypass filtration controller
Inventor: SUZUKI NORIHISA
IPC: B01D37/04
Filed: 1979-02-09
Abstract: PURPOSE: To perform the treatment of water effectively by saving chemical by the procedure in which a slow-speed stirred basin and a sedimentation basin are bypassed at the time when the turbidity of original water in a water purification plant is low and then introduced from a high-speed stirred basin directly to a filtration basin and at the same time the amount of chemical to add is controlled to a minimum.  
     CONSTITUTION: Original water injected with a coagulant in the high-speed stirred basin 2 is usually treated at the slow-speed stirred basin 3 to form flocs, sent to the sedimentation basin 4 to precipitate and remove the flocs, and then introduced into the filtration basin 5. And, at the time when the trubidity of original water is low, it is detected by the turbidity detection circuit 13 in the slow-speed stirred bypass controller 12 and then original water injected with coagulant at the high-speed stirred basin 2 is introduced into the filtration basin 5 and then filtered in the state of containing the nuclei of floas. At the same time, a bypass signal is sent to the chemical control panel 7 and also a command to alter the setting for the chemical to be injected to a limit amount necessary for forming the floc, are given.

Abstract: PURPOSE:To make it possible to measure the coating amount with precision in online mode, by measuring the weight of a coating material, sticking to the part which is not in contact with the substrate of an application roll, by collecting the coating material for a constant time by doctors. CONSTITUTION:A reverse roll coater is provided with application roll 11, pickup roll 12 and intermediate roll 13, and doctors 14 and 15 are fitted where roll 11 is not in contact with substrate (a). When the doctor width is B, the collection time is T and the collected coating weight and substrate running speed are (w) and (v), respectively, the coating weight per unit area of the substrate can be found by formula W=w/TBV. In this constitution, the depressing pressure and rotating speed of each roll are adjusted to adjust the film thickness of coating material P2. Next, the coating material of the 1st rotation which may cause an error is removed by doctor 14 and then doctor 15 is pushed for a constant time to collect the coating material thereby finding the coating amount from the said formula by measuring the weight. Thus, the measurement can precisely be taken in on-line mode.

Title: Code error correction system
Inventor: MORIYAMA YOSHIAKI
IPC: G06F11/10
Filed: 1984-01-27
Abstract: PURPOSE:To decrease the number of correction unable error patterns by making use of a bit corresponding to an error flag showing the presence or absence of a code error as well as a bit corresponding to data. CONSTITUTION:The error correction of X direction is carried out over an entire code block and the error correction of Y direction is carried out over an entire code block. Then the error detection of X direction is carried out again, and the error correction is carried out over an entire code block. These correction processings are carried out J times and then the error detection of X direction is carried out once more to finish corrections. In this correction system, the correction processings corresponding to the number of errors shown by an error flag is executed. At the same time, the error flags of a word having low error probability and a word having high error probability are set at ''1'' and ''0'' respectively when the error correction is over. The flags of other words can be decided by the next error detection. This ensures the effective correction of errors.

Filed: 1995-01-31
Abstract: PURPOSE: To reduce judging operation by a monitor staff by extending and setting the detection time of water level variation when earthquake occurrence is detected, and making detection, which is shorter than the set time, ineffective. CONSTITUTION: When a sensor 2b detects an earthquake, a detecting device 3 sends its information to an earthquake processor 6 which decides which of a fault of facilities and the earthquake a state change of a feed water facility equipment is caused and sends the decision result to a processor 4. When the earthquake is detected here, the length of the detection set time of a water level variation detection signal is increased to approximately one minute as an experimental value of continuance of the earthquake and further to the length of a period as a set value of the attenuation time of an impulse of the water level in a water tank depending upon the water tank and the structure characteristic of a building; when the detection continuance is shorter than the period, the detection of the water level variation signal is made ineffective.  Consequently, when the earthquake occurrence is detected, the detection time of the water level variation is extended and set and the detection which is shorter than the set time is made ineffective, so the earthquake can be discriminated from fault.
