Title: Automatic speed correction control system
Inventor: HAMADA KAORU
IPC: H02P29/00
Filed: 1979-04-02
Abstract: PURPOSE: To realize invariably-stable high-speed operation by automatically correcting the aging variation of a servo-system while eliminating the need for the adjustments and maintenance of operators, by automatically setting the best speed command value under carriage feed control.  
     CONSTITUTION: In artificial output operation when a carriage feed speed correction value is determined, control circuit 20 sends information on a desired operation mode to speed command value table 21, speed detecting circuit 31, etc., to command the servo-system to perform the operation. On the basis of the operation mode, table 21 applies a mean speed command value to speed command value storage part 22, which converts it into an actual speed command value, and D/A conversion part 23 obtains a servo-analog singal by converting to drive servomotor 25. On the other hand, counter 29 and timer 30 memorizing the control time, when circuit 31 receives an artificial output operation command, measure the actual operation time and then stores speed correcting method 32 with the result of the measurement to correct the value in command value table 27, thereby attaining invariably- stable high-speed operation.

Title: Signal switching circuit device
Inventor: TOMURO YASUTA
IPC: H03K17/62
Filed: 1979-04-02
Abstract: PURPOSE:To simplify a direct connection to a semiconductor integrated-circuit device by applying a switching signal to a 3rd input terminal and then by extracting signals, corresponding to 1st and 2nd input signals, from one terminal of a load resistance by switching. CONSTITUTION:Respective 1st-3rd differential amplifying circuits 20, 23 and 26 consist of 1st-6th npn transistors (TR) 18 and 19, TRs 21 and 22, and TRs 24  and 25. Then, TRs 24 and 23 constitute 1st and 2nd constant-current circuits which absorb constant currents from circuits 20 and 23 respectively, and 7th npn Tr27 constitutes the 3rd absorptance constant-current circuit which absorbs constant current I0 from circuit 26. Circuit 26 has 3rd input terminal 15 as a switching signal terminal, which is applied with a high level voltage higher than the common base bias voltage of TRs 24 and 25 to turn TRs 24 and 25 ON and OFF respectively, and consequently current I0 is all flowed through TR24. As a result, although circuit 20 is placed in an eperation state to derive the signal of the 1st input 13 as the signal of output 17, it is made possible to eliminate output 17 of the signal of the 2nd input 14 since TR23 is OFF.

Title: Optical coupling circuit
Inventor: ITO MASATAKA
IPC: G02B6/32
Filed: 1988-02-22
Abstract: PURPOSE:To attain highly efficient optical coupling even when the positional shear of optical elements is generated by arranging an optical prism whose incident face is not parallel with its opposed reflecting face between a coupling lens and a light receiving side optical element out of plural optical elements. CONSTITUTION:A beam 23 radiated from one optical element 21 is converted into an image by a lens 31. The image converted beam 23 is inclined from the optical axis 25 of the lens 31 due to a positional shear between a light emitting side optical element 21 and the lens 31. The optical beam 23 inclined from the optical axis of the lens 31 is made incident almost vertically on the incident face 12 of the prism 11, propagated through the prism 11 and made incident on a projecting face 13. When the beam is transmitted through the prism 11, the optical axis of the optical beam 23 goes parallel with the optical axis 25 of the lens 31 because an angle formed by the optical axis of the beam 23 and the projecting face 13 is slightly shifted from 90 deg.. Consequently, the optical beam 23 can be made incident vertically upon the end face of the light receiving side optical element 22 without generating an angle shear.

Title: Runaway protecting circuit for sequence controller
Inventor: MITSUO KAZUHIKO
IPC: G05B9/02
Filed: 1986-02-25
Abstract: PURPOSE:To prevent such a case where a sequence programs is changed by noises, etc., during operation of a controller by deciding whether a D flip-flop has a run mode or a program mode from execution of the signal processing routine and using the output of said flip-flop to control the open/close of an OR gate. CONSTITUTION:The NPR address is read out regardless of a run mode or a program mode and therefore the '0' output of a decoder 2 is changed to a low level from a high level. This '0' output is used as the clock signal of a D flip-flop 1. In a run mode '1' is written in the NPR address as data and therefore the data D0 of a data bus is set at '1'. Thus the output Q is latched at a high level since the input D is equal to '1' when the clock signal is supplied. Then the output of an OR gate 4 is kept at a high level regardless of the state of the write signal, the inverse of WT, which is regarded as an active low level. Thus it is inhibited that the write signal, the inverse of WT, i.e., the input at the other side of the gate 4 is supplied to a write control terminal, the inverse of WE, of a memory 5.

Abstract: PURPOSE:To simplify a formation of a circular sectional rolled core by constituting a rolled core forming device with a slitter mechanism to change a material width of the rolled core, a cut width controlling mechanism to control cut width of the material and a takeup mechanism. CONSTITUTION:A rolled core material 2 on a reel stand 1 is cut with slitter round edges 8 and 9 by way of guide rollers 3 and 4, grooved guide rollers 5a, 5b and 6a, 6b. Next, the cut material 2 is given a tension by means of friction materials 36 and 37, a center position of the material width is kept constant at all times with automatic center holding rollers 31a and 31b, and the material is coiled to a product 27 on a takeup jig 29 provided on a winder 28. In this constitution, alitter round edges 8 and 9 retained on a free rotary shaft 12 are controlled with a profiling die 20, thereby changing the width to cut to cutting in curve. The width to cut can thus be changed continuously, and hence a circular sectional rolled core can made reasonably.

Title: Hanging particle accelerometer
Inventor: JIYOOJI TEII PINSON
IPC: G01P15/13
Filed: 1990-02-21
Abstract: PURPOSE: To exactly detect relative motion of a particle by detecting the absorption of light beam when a charged particle between electrode plates moves from a neutral position to a light beam path and controlling an electrostatic field which recovers the particle according to the detected value. CONSTITUTION: A charged particle 20 is suspended in an electrostatic field 22 along a sensing axis 24. Power for the electrostatic field 22 is given by a power source 26 which provides an electric potential difference between an upper plate 28 and a lower plate 28' arranged in between parallel planes above and below the charged particle 20. The light beams emitted from light emitting diodes 32 and 34 which are parallel to the surfaces of the plates 28 and 28' go into each light detector 36 and 38. If the particle moves from a neutral position to a light beam path, it absorbs the light beams and so the outputs of detectors 36 and 38 vary.  A position control system 40 monitors the outputs of the detectors 36 and 38, sends signals corresponding to the absorption of light through position feedback loops 42 and 44 to the power source 26 and controls the particle so as to return to the neutral position.
