Title: Fiber inspecting apparatus
Inventor: HIRATA TAKAAKI
IPC: G01M11/00
Filed: 1994-11-29
Abstract: PURPOSE: To provided an inspecting apparatus, whose measurable distance is not limited by the spectral line width of a laser light source, by obtaining the position or the reflectivity of the reflecting point of an object to be measured based on the change of a beat signal with respect to the modulated frequency obtained by modulating the transmitting frequency of the laser light source. CONSTITUTION: The transmitting frequency of a semiconductor laser 15 is modulated by the modulating frequency having the specified duty ratio, and the modulated frequency is linearly increased with respect to time. When there is the difference in an optical-path length between the signal light from an object to be measured 1 and the reference light from a mirror 2, the phase of the frequency modulation of the signal light is delayed by the time difference Δt corresponding to the difference in optical-path length. The spectrum of the beat signal obtained in a photodiode 4 is change with the change in modulated frequency as the period. A voltage, which is applied on an A/D converter 13, is also periodically changed in accordance with the change of the spectrum.  The data converted in the A/D converter 13 undergo high-speed Fourier transform and analysis in a signal processing part 14, and the time difference Δt is obtained based on the obtained period. The reflectivity of the reflecting point is obtained based on the position of the reflecting point of the object to be measured or the intensity at the reflecting point.

Title: Line filter
Inventor: IMOTO NARIISA
IPC: H03H7/09
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a compact and lightweight line filter which can eliminate electromagnetic wave noises and also can shape the waveform by connecting a series transformer between an AC power supply and a load to make the phase reverse to the power voltage. SOLUTION: The secondary winding of a series transformer TR is connected in series between an AC power supply 1 and a load L as a means that shapes the waveform of the power voltage E1, so that the phase difference is set to 180 deg. against the voltage E1. In such a constitution, the power source higher harmonics and the electromagnetic noise component passing through a filter circuit 2 of the voltage E1 are subtracted from the power supply via the TR. The noise component E2 is removed out of the voltage E1 and the load voltage E4 is obtained. Therefore, only the sine wave voltage is applied to the load L. As a result, the power source higher harmonics and the electromagnetic noises entering from a power line and a signal line can be eliminated and also the waveform of the inverter output, etc., can be shaped in a comparatively simple way.

Inventor: YAMAGAITO TAKESHI
IPC: G11B7/00
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To rapidly detect a boundary between a recorded area and an unrecorded area by reading out the top and end addresses of a write-in objective logic track from a recording support information area on a disk, moving an optical pickup from the top to the end of its groove in the radial direction and tracing with a vicinity track of nearly inside from a vanishing point of an RF signal as an origin. SOLUTION: The number of physical tracks of the unrecorded area are counted while moving the optical pickup to be stored in a register. When the count value A isn't 0, the processing seeking the top of the unrecorded area is executed. The track count search processing for moving the optical pickup to an inner peripheral side by a distance jumping over (A+X+1) pieces of grooves (tracks) from the present position is performed. X is a correction value, and 1 is for securing a margin. Thereafter, the boundary point between the recorded area and the urarecorded area is detected while repeating one track jump processing and information read processing to the inner peripheral side.

Title: Fixing device
Inventor: OKAZAWA KAZUHIKO
IPC: G03G15/20
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the curling of the top end of a recording material by gravity, after the top end comes out of a nip and to prevent winding on a roller by carrying the recording material at a fast speed, until the top end of the recording material comes out of the nip and at a slow speed, after the top end of the recording material comes out of the nip. SOLUTION: When the recording material 102 has a lot of thermoplastic resin like an OHP sheet, the carrying speed of the recording material 102, that is, the rotational speed of a fixing roller 104a, until the top end of the recording material 102 comes out of the nip is defined as V1 , the carrying speed of the recording material 102, that is, the rotational speed of the fixing roller 104a, after the top end of the recording material 102 comes out of the nip is defined as V2 and the rotational speed V1 is set faster than the rotational speed V2 . Thus, the carrying speed of the recording material 102 is slow after its top end comes out of the nip, so that the excessive heat of the fixing roller 104a is not imparted to the top end of the recording material 102 having the thermoplastic resin. Therefore, curling never occurs to prevent winding on the roller.

Title: Filter system
Inventor: KAKO TAKASHI
IPC: H04L27/01
Filed: 1986-12-10
Abstract: PURPOSE:To form a stable filter where the loop gain is always constant by providing a tap coefficient control circuit whose output changes with a level of an input signal in an automatic equalizer used for a data communication MODEDM or the like. CONSTITUTION:An automatic equalizer is provided with a control circuit 6 and multipliers 71-n and the output level of the control circuit 6 varies with the quantity of the input signal. For example, when the input signal is larger, the output of the control circuit 6 is decreased and the output is increased when the input signal is small. The output of the control circuit 6 is inputted to the multipliers 71-7n provided to each tape. With the input signal increased, the loop gain is increased and an error signal from a discrimination section 4 is increased. However, since the output of the control circuit 6 is decreased, tap coefficients C1-Cn being outputs of the multipliers 71-7n are decreased to keep the loop gain constant. That is, the loop gain is controlled to be constant by the feed-forward system.

Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a slitter device to cut a carrier tape with high size precision at a slit process in manufacture of a carrier tape and further suppress the generation of slit burrs harmful to an electronic part. SOLUTION: A slitter device for a carrier tape is a device to cut a thermoplastic sheet, in which pocket part 2 and sprocket holes are continuously molded throughout a multitrain, into constant widths in respective trains by a slide part between upper and lower rotary cutters 5 and 6. The pocket part 2 of each train is caused to pass through the groove 3 of an inlet positioning guide 1 arranged situated upper stream from the rotary cutters 5 and 6. Since the groove 3 is extended from this side of the rotary lower cutter 5 to a place right before a cutting part along a periphery, zigzagging of a paper sheet during cutting is prevented from occurring. A take-off tension roll 9 is provided to retract a cut sheet to a place situated downstream from the rotary cutters 5 and 6 and apply a constantly specified tension on a paper sheet after cutting.  The generation of slit burrs is suppressed by preventing rolling in of the paper sheet to the rotary cutters 5 and 6.

Title: Drawing-out gap correcting mechanism of paper
Inventor: OIGO SATORU
IPC: B65H7/12
Filed: 1989-11-14
Abstract: PURPOSE:To secure an adequate gap amount constantly by detecting the conveying condition after a drawing-out with a transmitted light sensor, and regulating the gap between a gate roller and a picker roller responding to the detecting result. CONSTITUTION:A mechanical completion 9 calculates the conveying speed of papers 1 at the drawing out time from the passing time with a transmitted light sensor 7 positioned immediately after the drawing out position, compares it with the speed of the conveyer system, and stores the difference. Since the gap amount is small when the stored data of conveying a standard number of sheets exceeds a set value, it is judged that it acts as a resistance to disturb a smooth conveyance, and an order is output from the mechanical completion 9 to rotate a motor 10. And in this case, an encoder 11 is operated to stop the motor after a standard rotation is over. By the rotation of the motor 10, a gate roller 5 is moved 1 standard amount through a gear with screw 12 and an arm 13, and the drawing out gap between the gate roller 5 and a picker roller 6 is expanded adequately.
