Title: Low-pass filter
Inventor: OOTA SHIGENORI
IPC: H03H11/04
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To relax degradation of an amount of attenuation on a high-pass side and to relax restriction upon gain and noise characteristics of a differential amplifier by serially connecting a secondary filter circuit in front of an emitter follower type low-pass filter and using the filter circuit in common as a load of a differential amplifier. SOLUTION: A resistance 6 is connected to a front step of an emitter follower type low-pass filter, resistances 1, 3 and 5 are connected as a load of a differential amplifier, a capacitor 2 is connected between connection parts of the resistance 1 and the resistance 3 and a capacitor 4 between connection parts of the resistance 3 and the resistance 5. Also, a capacitor 4 is connected between the connection parts of the resistance 3 and the resistance 5. A transmission function becomes the one in which a 4-th low-pass filter circuit and a secondary high-pass filter are combined. Filter characteristics come to be attenuated by 12 dB/oct on the high-pass side. When a gain of a specific value is tried to gain, an emitter resistance can be made small and an NF of the differential amplifier can be improved.

Title: Detection of weld line
Inventor: TAMAI SEIICHIROU
IPC: B23K9/127
Filed: 1982-09-21
Abstract: PURPOSE:To enable the detection of a weld line near the arc and to facilitate the automation and robotization of arc welding by disposing a photodetection means so as not to face to arc light in the stage of detecting the weld line with light projecting and photodetecting means and a data processing means. CONSTITUTION:A weld line 11 is detected while arc welding is performed by using a welding line detecting sensor which projects a luminous flux having approximately a near IR wavelength by a light projecting means 2 onto the welding work 1, receives the image of said light with a photodetecting means 6, calculates the position of the image of the light by the output signal thereof, and detects the weld line by a data processing means 9. If the means 6 is so set as not to face to the arc 12 in this state, there is no direct incidence of the arc light nor sticking of a spatter 13. The device is therefore usable as a visual sensor for an automatic welding machine or a visual sensor for an arc welding robot.

Abstract: PROBLEM TO BE SOLVED: To remove powder dust, etc., by bringing a first polishing tape traveling in the forward direction with respect to the traveling direction of a medium at a speed higher than the speed of the medium into sliding contact with the medium, then bringing a second polishing tape traveling backward with respect to the traveling direction of the medium into sliding contact with the medium. SOLUTION: The surface of the magnetic thin film of a continuously traveling raw medium 2 is first brought into sliding contact with the first polishing tape 1 at the time of passing a first polishing means 3. As a result, the powder dust of a relatively large diameter of the powder dust sticking to the surface of the magnetic thin film is rapidly polished and is removed to the traveling direction side of the raw medium 2. The raw medium 2 past the means 3 passes a second polishing means 5. At this time, the surface of the magnetic thin film is brought into sliding contact with the tape 4 and the powder dust of a relatively small diameter which tends to be the cause of a drop-out is removed from the surface of the thin film.  At this time, the powder dust of the relatively large diameter which is the cause for flawing is already removed at the time of passing the means 3 and, therefore, the raw medium is polished without the occurrence of scratching flaws and the good magnetic layer surface is obtd.

Title: Imaging point adjusting system in electron tube recorder
Inventor: IKEZU YOUHEI
IPC: G03B27/32
Filed: 1978-12-30
Abstract: PURPOSE: To obtain a distinct imaging point with good accuracy by disposing a solid-state image sensor on the plane identical to or in a conjugate relation with the recording medium plane and adjusting the luminescent spot image by the illuminance distribution signal of luminescent spot in this sensor.  
     CONSTITUTION: The fluorescent face 1b of a cathode ray tube CRT1 and the photo detecting face of a solid state image sensor CCD5 are so disposed as to assume a conjugate relation with respect to a lens 4. The electric signal output distribution of the CCD5 varies with the sharpness of the scanning luminescent spot on the fluorescent face 1b of the CRT1. If the luminescent spot on the fluorescent face 1b is sharp, hence if the imaging on the CCD5 is sharp, the electric signal output distributiion of the CCD5 is limited to a range where the peak value of the illuminance ratio is high and the illuminance distribution is narrow. Thereupon, the peak value and the allowance width of the half value width of the illuminance ratio are beforehand determined and the electric output signal of the CCD5 is actually measured while it is being moved on the optical axis, thence the position where the output of the CCD5 comes within said allowance width is obtained, whereby the sharp imaging point may be obtained rapidly with good accuracy.

A specific value is selected out of the above-mentioned range from the requirement to both N and D for a phase code. The same procedure is available also to an FM code.
