Title: Washing method of filtering device
Inventor: IWAI MASA
IPC: B01D29/62
Filed: 1982-11-22
Abstract: PURPOSE:To perform sufficiently a stripping of turbid matter throughout the whole layer without causing an effluent of filter medium by using a small amount of backwashing water, by settling a filter layer into a stationary fluidizing state after producing a slagging phenomenon at the lower part of the layer by supplying air, and repeating a process of filling water again after stopping the air supply. CONSTITUTION:Air is supplied from an air supplying pipe 4 to produce a slagging phenomenal part 7 at the lower part of a filter layer 2. The water level 8 in a filtering tower 1 rises as much as a resident air portion. The phenomenal part 7 begins to collapse from its lower side, and turbid matter is stripped off at this time because filter medium is violently agitated, and the layer 2 is settled into a stationary fluidizing state formed at the time of air backwashing. Next, when an air supply is stopped, the water level 8 falls to the position settled before the air supply, and the stripped turbid matter remains at the upper part of the layer 2 because the settling velocity of the medium is faster than that of the turbid matter. The stripping of the turbid matter and its upward movement are efficiently performed by repeating this cycle even if the non-stripped turbid matter remains in the inside of the layer 2 by one cycle, and the turbid matter is discharged from the upper part by an ordinary water backwashing.

Title: Optical cable
Inventor: TANAKA SHIGERU
IPC: G02B6/44
Filed: 1987-08-18
Abstract: PURPOSE:To suppress the deviation in the propagation time of the respective signals at the time of transmission of parallel signals down to a permissible value or below by suppressing the fluctuation in the optical path light of optical fibers to be housed in an optical cable to a prescribed value or below. CONSTITUTION:The plural optical fibers 2 attached with single connectors 3 at both ends are housed in the optical cable 1 of, for example, a single fiber assembly type and the fluctuation in the optical path length between the connectors 3 is kept at <=50cm. A fluctuation is generated in the length of the fibers 2 in the cable 1 by a difference in a lay ratio and the difference in the elongation rate by the fluctuation in the letting out tension of the fibers 2 at the time of production. The fluctuation in the optical path length of the respective fibers is, thereupon, actually measured and the mounting position of the connector 3 is so adjusted that the fluctuation is suppressed within the above-mentioned value. The deviation in the propagation time with the cable 1 for connecting information apparatus to each other is then eliminated.

Filed: 1993-08-19
Abstract: PURPOSE:To effectively decrease the burrs generated at an arc angle by executing laser cutting of a work by moving the work or laser releasing head by biaxial control. CONSTITUTION:The deceleration control of an X-axis motor 2 is started in the case of cutting of the small arc angle so as to enter from an X-axis direction and to progress in a Y-axis direction. The control is so executed as to start a Y-axis motor 3 at a point B, to stop the X-axis motor 2 at a point B and to regulate the speed of the Y-axis motor 3 to a specified speed at a point D. The deceleration and acceleration speeds in the X-axis direction by the X-axis motor 2 from the point A to the point C are set at, for example, about 2500mm/sec<2> from the cutting tolerance, vibration conditions, etc., of the work. On the other hand, the increasing speed in the Y-axis direction by the Y-axis motor from the point B to the point D is set at about 3750mm/ sec<2> higher than the deceleration and acceleration speeds in the X-axis direction. The speed-up acceleration of the Y-axis direction is determined from a graph indicating a relation between the time lag t0-t1 between the deceleration start point t0 in the X-axis direction and the speed-up start point t1 of the Y-axis direction, the increasing speed in the Y-axis direction and the cutting speed V.

Abstract: PROBLEM TO BE SOLVED: To provide a shape conversion technique for easily generating a three- dimensional shape from a give two-dimensional graphic (character data of an outline font, for example). SOLUTION: A two-dimensional shape expressed as an outline on a plane is inputted to an electronic computer and the inputted two-dimensional shape is moved in a direction independent of the plane in a designated sense and by a designated quantity while the outline is deformed. A three-dimensional shape is obtained by constructing a side face using the loci of the movement. More specifically, the two-dimensional shape is duplexed (step S1), one of which is fixed and the other is moved (step S2). Outline points to which the two-dimensional shapes correspond or the outline points to which the respective two-dimensional shapes correspond and outline points before and after these outline points are selectively connected (step S3). Thus, the side face of the three-dimensional shape is constituted by the connection.

Title: Rewind controller of tape reader
Inventor: HATSUTORI SEIICHI
IPC: G11B15/18
Filed: 1983-11-02
Abstract: PURPOSE:To miniaturize a reel motor by setting at first a reel motor at adversing low speed by a rewind command, then at adverse high speed, by detecting a rewind stop code and by bringing back the controller for the excessive amount to position. CONSTITUTION:The controller converts the number of rotation of a capstan motor 12 into a normal rotation low speed by a rewind command, and when the motor 12 reaches the reversing low speed, the controller actuates an FM11 to rewind the tape reader. The controller adversely accelerates the number of rotation of the motor 12 little by little by the rewind of the tape, and after the controller detects a top code punched on a paper tape, the controller adversely decelerates the number of rotation of the motor 12. When the motor 12 reaches an adverse low speed, the controller actuates a BM11 to stop temporarily the tape. During this time, the controller stores the number of sprocket signals or the number of rewind stop code in a receivable counter (R.C)40. When the tape stops, the controller converts the motor 12 into a normal low speed, and when the motor reaches a normal low speed, the controller actuates an FM14, sends the tape in the correct direction, and actuates the BM11 to stop the tape.

Besides, from a comparing amplifying section 6, correcting control current I2 which is more when the load fluctuation is more and which is less when the load fluctuation is less is fed to a second field winding 7, and the output voltage against the load fluctuation is stabilized. As a result, the constant output voltage stabilized against both the steady-state load and the load fluctuation can be obtained.

Filed: 1988-08-19
Abstract: PURPOSE:To obtain a protection circuit dispensing with fuses, etc., after the release of short protecting operation by performing short protecting operation at the voltage divided in resistance into another supply voltage among the supply voltages to protect shorts. CONSTITUTION:When supply voltages V1 and V2 are reduced by an abnormal factor and lowered to 0.6V and more than the base potential of a 4th transistor 17 whose emitter is connected to the line there, the 4th transistor 17 is turned ON, the base potential of a 3rd transistor 16 connected to the 4th transistor 17 through a resistance R5 is lowered and this 3rd transistor 16 is also turned ON. The 3rd transistor 16 shorts the emitter and base of a 2nd transistor 15 switched over from a power source V2 to turn it OFF. On that account, no current gets to be supplied from the power source V2, so that the circuit can be protected from shorting. When the shorting factor is removed and a control signal terminal 12 of power switching is set to 'L', the 4th transistor 17 and the 3rd transistor 16 are turned OFF and the short protecting operation is released.
