Title: Injection molding equipment of plastic magnet
Inventor: YUKIMURA KAZUHIKO
IPC: H01F13/00
Filed: 1985-03-15
Abstract: PURPOSE:To make a demagnetization current always constant by making the demagnetization current flow in a definite direction by detection means and by sending a detection signal when a required set value is obtained. CONSTITUTION:After an excitation operation is finished, thyristors 13, 15 are operated, a demagnetization current flows in the direction shown by a broken line arrow and a demagnetization magnetic field is generated from electromag netic coils 6, 7. A meter relay 20 detects the demagnetization current when the current of a predetermined direction flows and the relay 20 sends a detection signal to a control circuit 21 when the demagnetization current becomes to a level previously set in the relay 20. When the circuit 21 receives the detection signal, the thyristors 13, 15 are made off and the demagnetization current is cut off. This enables to maintain the demagnetization current always at a con stant level irrespective of the variation of the resistance of the coils 6, 7.

Title: Dust removing apparatus
Inventor: HORI MITSUTAKA
IPC: E02B5/08
Filed: 1980-04-16
Abstract: PURPOSE: To remove even the scum or dusts unadhering to the rotary drum, by installing a scraper and a raking claw in the rotary drum for the use of removing the scum or dusts in the settling pond of the sewage disposal plant, etc.  
     CONSTITUTION: The said rotary drum 1 has many annular plates 2 parallelly arranged with an interval; a scraper 15 whose tips are cutting into gaps between annular plates, and a raking claw 8 piercing through prescribed annular plates, are installed in the rotary drum 1. The raking claw 8 is connected to an arm 14 eccentrically attached to the rotary shaft 12 of the rotary drum 1; hereupon, the raking claw 8 is arranged so as not to collide with the scraper 15 and to sink as far as the inner edge of the annular plate 2, when the raking claw 8 is at the position of the scraper 15. Accordingly, the dusts residing between annular plates 2 are removed and recovered by the scraper 15; however, thereby unremoved dusts are moored by the raking claw 8 because the raking claw 8 is jutting out of the outer circumference of the drum 1 at the position excluding the scraper 15; thus moored residual dusts are recovered by the scraper 15 while the raking claw 8 sinks into the scraper zone.

IPC: H03K5/08
Filed: 1987-03-05
Abstract: PURPOSE:To obtain a comparator with fast response speed and high accuracy by providing a bypass circuit giving an output of a differential stage to other differential stage while bypassing differential stages on its way. CONSTITUTION:An input signal is amplified by a differential stage Dl, given to a differential stage D2 through a level shift circuit S, transistors (TRs) Q5, Q6 and Q13, Q14 are started by the signal and D1, D2 are started at the same time. Just after an input signal is changed, the output of the D1 is directly given to the TRs Q13, Q14, an output Vout is changed to eliminate the transmission delay by the D22. The gain of the comparator in this case is given as a product between the gain G1 of the Dl and a gain G''3 by the TRs Q13, Q14. In driving elements Q9, Ql0 of D2, the gain of D3 is the sum of gains G'3 and G''3 by the TRs Q9, Q10 and a sufficient gain of G1G2(G'3=G''3) as a whole is obtained. Just after the input signal is changed, the signal passes through the differential stage and the number of stages is decreased, the reply time is decreased and then sufficient gain is obtained by giving the signal thorough each differential stage to establish the high performance comparator.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To compensate the difference in rotating speed between a contact roller and a thread package in the transferring from a thread floating winding process to an ordinary winding process. SOLUTION: A floating winding process with a contact roller CR held in a non-contact state with respect to a bobbin B, is executed, the contact roller CR is contacted with a surface of a thread package when a thickness of the thread package reaches a predetermined value, and a BH1 motor for rotating and driving the bobbin holder BH1 is switched to a feedback control on the basis of a rotating speed of the contact roller CR.  Then the deviation of a rotating speed instruction value to the BH1 motor after the lapse of a predetermined time from the switching of the control, from a prospective rotating speed instruction value corresponding to a prospective rotating speed calculated on the basis of an expression is determined, and then a value of the winding density in the expression is corrected on the basis of the deviation amount for controlling the rotation and driving of the bobbin holder BH in the thread winding process thereafter.

Title: Fusion splicing method for optical fiber
Inventor: ISHIKURA AKIHIKO
IPC: G02B6/24
Filed: 1988-03-04
Abstract: PURPOSE:To simplify the fiber connection work and to shorten the connection time with a low-cost device by allowing a part of each optical fiber to face a guide groove of a supporting base and applying an oscillation force to both optical fibers at the time of positioning. CONSTITUTION:Parts of two optical fibers 7, 8 whose terminals are preliminarily formed are allowed to face guide grooves 3 and 4 of a supporting base 1, and they are pressed in the direction perpendicular to axial lines to position them on the supporting base 1, and thereafter, terminal faces of optical fibers 7 and 8 are butted and they are melt-fixed by heating. Since the oscillation force is applied at the time of pressing both optical fibers 7 and 8 in this case, both optical fibers 7, 8 are surely guided to bottoms of guide grooves 3 and 4. Thus, the fiber connection work is simplified in case of connection of multicore optical fibers because the occurrence of axial deviation is reduced at the time of positioning of optical fibers 7, 8. In case of connection of single core optical fibers, fibers are connected with a low-cost device and the fiber connection time is shortened because a driving device, etc., which is required in a conventional method is unnecessary.
