Title: Luminance control circuit of oscilloscope
Inventor: TANAKA HIDEHO
IPC: G01R13/26
Filed: 1991-05-17
Abstract: PURPOSE:To realize a luminance control circuit of an oscilloscope which prevents occurrence of nonuniformity in luminance. CONSTITUTION:A luminance determination circuit 30 determines a set luminance level. In accordance with the determined luminance level, a luminance selection circuit 20 operates one set of a plurality of amplifiers included in a waveform correction circuit group 10 and being different in an amplification degree and a plurality of waveform correction circuits forming sets with these amplifiers and conducting optimum waveform correction in accordance with a signal amplitude, for an output of a prescribed amplitude from a limiter 50. In the case of fine adjustment of luminance, the limiter 50 adjusts finely an input signal to the waveform correction circuit group 10 within the prescribed limits. The output of the waveform correction circuit group 10 is amplified by an amplifier 60. The output from the amplifier 60 is superposed on a bias voltage of a grid of a CRT 100. Accordingly, nonuniformity in the luminance does not occur in a range from the time of low luminance to the time of high luminance.

Abstract: PURPOSE:To remove the heat produced in a can by constituting the can between a rotor shaft and wheel so as to cover the front end of the rotor shaft and isolate the inside of a rotating machine from the outside atmosphere and forcibly cooling the can. CONSTITUTION:When a conductive material, such as stainless steel, etc., is used for a can 11, an eddy current is generated in the can 11 and the can 11 is heated by the Joule heat produced by the eddy current. When the can 11 is heated to a high temperature, a trouble is produced to the can 11 and the can 11 cannot work as a magnetic coupling. Therefore, the can 11 is cooled through a cooling housing 12 by making a coolant 12c, such as water, etc., to flow into the housing 12 through an incoming coolant pipe 12a and outgoing coolant pipe 12b. The can 11 is not united with the cooling housing 12, but is separated from the housing 12.

Abstract: PURPOSE:To eliminate the shaking of a reference mirror drive mechanism and the influence of frequency fluctuation of an interference signal due to a traveling speed by vibrating the reference mirror with a frequency which is faster than the traveling speed and then extracting high-frequency components for detecting the output change of the interference signal. CONSTITUTION:Light with a short coherent length from a light source 1 is divided into a reference light path 4 and a measurement light path 5 by a beam splitter 3 and a reference mirror 6 and a measured target 7 are laid out at each. The reference mirror 6 is fixed to a movable body 8 via an epizo element 9 and is moved in the direction where the light path 4 is extended by a drive mechanism 10. The flux of reflected light from the reference mirror 6 and the measurement target 7 is converged on a light receiver 12 via the beam splitter 3 and a condenser lens 11. In this case, the epizo element 9 vibrates the reference mirror 6 at a higher frequency than the traveling speed V, superposes high-frequency components on low-frequency components caused by the traveling of the reference mirror 6, and then eliminate the low-frequency components via a BPF. Then, a device 17 for detecting the amount of travel is used to detect the position of the target 7 containing amplitude vibration.

Title: Position orientating method for submarine coaxial cable
Inventor: HATA TERUO
IPC: G01V3/08
Filed: 1981-09-11
Abstract: PURPOSE:To orientate the cable position accurately without the influence of the noise such as the earth magnetism, by supplying currents, where low frequency ACs slightly different in frequency are superposed to DCs, from current sources of both terminal stations of a submarine coaxial cable. CONSTITUTION:Currents where low frequency ACs are superposed to DCs are supplied in directions of arrow from current sources G1 and G2 of both terminal stations of a submarine coaxial cable. AC components shown in figure are flowed in the cable by the sum of AC components supplied from current sources G1 and G2, and a desired magnetic field intensity is obtained throughout its length. Though a beat signal is generated because frequencies of AC components from current sources G1 and G2 are different from each other by about 0.1-1Hz, the influence of standing waves in case of flowing of the same frequency is eliminated. The beat signal is detected by a magnetic sensor to facilitate the distinction from the noise magnetic field, and thus, the position orientation is accurate.

Filed: 1990-05-31
Abstract: PURPOSE:To perform printing with a printing paste in a uniform and accurate printing form by a method wherein a vacuum unit for sucking a screen mask is disposed around a stage. CONSTITUTION:A mounting substrate 3 is mounted on a stage 4. A screen mask 2 provided with through-holes of a required circuit pattern is positioned on a predetermined position of the mounting substrate 3, and both are held with substantially no gap in between. After that, the pressure of a vacuum unit chamber 6 surrounded by a vacuum unit 5 is reduced to a predetermined degree of vacuum by a vacuum pump or the like, whereby a part of the mask 2 other than a through-hole circuit pattern is sucked on the mounting substrate 3. Thereafter, a squeegee 1 is horizontally moved while abutting on the screen mask 2. A printing paste, such as a solder paste, is printed on the mounting substrate 3 through the through-hole circuit pattern of the mask 2, and the stage 4 is slightly moved down. The reduced pressure in the vacuum unit chamber 6 allows the printing paste remaining in the through-holes of the screen mask to completely pass through to ensure printing on the mounting substrate 3.
