Abstract: PURPOSE:To decrease the number of installation sets of a transducer for transmitting a measuring signal placed in a job site by constituting a switching circuit for the measuring signal of a multipoint changeover switch placed on a monitoring board, and a relay with a non-open-circuit contact. CONSTITUTION:When contacts of a multipoint changeover switch SE of a monitoring board II are all turned off, each measuring signal outputted from each transducer AT-1 to AT-n through contacts (b) of relays X-1 to X-n is transmitted separately to measuring instruments A-1 to A-n. On the other hand, when a contact SE-1 is selected by the multipoint changeover switch SE and a turn-on operation is executed, the relay X-1 operates and a normally closing contact (b) and a contact (a) are opened and closed, respectively, a measuring signal outputted from the transducer AT-1 flows through a loop for returning to the transducer AT-1 through the measuring instrument A-1 of the monitoring board I from a measuring instrument A of the monitoring board II, and by only providing the transducer of the measuring signal installed in a job site by one set each at every signal, the measuring signal can be transmitted separately to the monitoring board I and selectively to the monitoring board II.

IPC: B01J20/285
Filed: 1994-05-23
Abstract: PURPOSE:To realize separation and recovery while sustaining the function of biological element in the mobile phase of single water system by employing a filler wherein the balance of hydrophilicity and hydrophobicity on the surface of fixed phase can be varied depending on the temperature while fixing the mobile phase to the water system. CONSTITUTION:The filler being employed in the separation of solute, e.g. a biological element or a cell, includes a filler where the balance of hydrophilicity and hydrophobicity on the surface of fixed phase can be varied by an external signal, e.g. temperature variation, while fixing the mobile phase to the water system, e.g. a filler where the surface of a carrier having amino group, carboxyl group, hydroxy group, etc., on the surface is chemically modified with polyalkyl acryl amide having an amino group at the end or a copolymer thereof. When such filler is employed, a biological element is adsobed to the hydrophobic surface upon reaching a critical temperature and it is separated or exfoliated as the temperature drops. Consequently, an organic solvent, a surfactant, etc., does not act as a dirt and the inventive method can be utilized in the separation, as well as analysis, while sustaining the function of protein or cell.

IPC: F16D1/06
Filed: 1993-04-13
Abstract: PURPOSE:To secure the versatile use performance, facilitate manufacture, and improve the production efficiency at a low cost by installing a shaft having a D cut part at the edge part and forming a bent part engaged with the D cut part on a tubular body consisting of a cylindrical metal member fitted with the shaft. CONSTITUTION:An electromagnetic clutch 1 is installed on a shaft 19 and constitutes a shaft/tubular body connecting structure, together with a tubular body 20. The tubular body 20 is manufactured by roll-working a cold press rolled steel plate through the forming work, and further the shaping of an axis hole 20c and the cutting-off process. A pair of engagement pieces 20b are bent through the plastic work, and the top edges are joined, and the axis hole 20c having a D-shaped section is formed. Since the engagement piece 20b engaged with the D cut part 19a of the shaft 19 is bending-worked, the necessity of the posterior work as in the conventional is obviated, and the manufacture is facilitated. Further, since the plate members having different plate thickness are used for the cold press steel plate before the roll shaping, the cutting work process after the roll shaping can be omitted.

Title: Magnetic recording and reproducing device
Inventor: HIROSE KOJI
IPC: G11B15/48
Filed: 1989-04-28
Abstract: PURPOSE:To smoothly control a tape by independently driving or stopping respective reels on a taking-up side and a supplying side. CONSTITUTION:In the case of fast feeding, the rotation start command 62 of a reel motor 3 on the taking-up side is outputted to a reel driving circuit 5 on the taking-up side by a control circuit 6 and the torque control output 64 of the reel on the taking-up side is outputted besides. Then, the reel 3 on the taking-up side is started to be slowly rotated by low torque. After the command 62 is outputted, a pulse 71 outputted by the rotation detection circuit 7 of a reel motor 2 on the supplying side is counted. Then, by outputting the rotation command 61 of the motor 2 to a reel driving circuit 4 on the supplying side when the counted number reaches a fixed number, the fast feeding is started. The torque control outputs 63 and 64 of the motors 2 and 3 are outputted simultaneously with the start of the fast feeding and the low torque is returned to the high torque. Then, the speed of the fast feeding is made an expected speed. By returning the speed to the expected speed after the sagging of the tape is slowly taken up by the motor 3, the tape is smoothly controlled.

Filed: 1979-08-28
Abstract: PURPOSE: To always obtain a certain value of the bar code width with no effect give due to the difference of the reading speeds and with a low cost, by reading the bar code width with the signal synchronized with the pulse sent from the encoder.  
     CONSTITUTION: The bar code reading head 2 is held by the hands to be scanned in the direction SCN and on the paper surface 1 onto which the bar code is printed. And the shfit at that time is given in synchronization with the speed of rotation of the motor 4 of the servo motor 3 connected to the head 2. In this case, the encoder ENC5 encodes the speed of rotation and then sends the encode signal to the reading circuit 8. On the other hand, the bar code data read by the head 2 is converted 6 into the electric signal and then supplied to the circuit 6 after amplification 7. Thus the circuit 8 reads the bar code data in synchronization with the signal produced from the ENC5. In this way, the bar code width of a certain value can be obtained.
