Title: Distance amplitude correcting device
Inventor: OOTA YASUKI
IPC: H01L27/02
Filed: 1979-10-29
Abstract: PURPOSE:To secure an accurate correction for the distance amplitude even when a complicated control signal is delivered, by storing previously the control signal in a digital memory and then delivering the stored value successively in a distance amplitude correcting device used for the ultrasonic flaw detection by the pulse reflection method. CONSTITUTION:The data are written into the digital memory 11 in the calibration mode for the signal which controls the amplification factor of the amplifier 6. Then the calibration mode is switched to the actual flaw detection mode. The transmission pulse, if produced, is converted into the ultrasonic wave through the probe 1, and the echo reflected by the the defect or like in the subject is converted into the electric signal to be supplied to the amplifier 6. This echo is then displayed on the A scope 4. When a distance amplitude is corrected, the synchronous pulse is sent to the sunchronous circuit 10 simultaneously with the output of the pulse 13. The circuit 10 reads successively the control data in the memory 11 in a proper time interval to send it to the D/A converter 8. The converter 8 converts the digital data in the memory 11 into the analog control signal to control the amplification factor of the amplifier 6. Furthermore, the route length can be obtained directly when a correction curve is produced since the device 9 which calculates he value of interpolation and then produces the data to be written into the memory 11 is used.

Abstract: PURPOSE:To improve the miniaturization of the optical system by providing a cylinder on part of which a film with a visual light transmitted therethrough is wound, collecting the transmitted light from other optical system onto a film face and driving the cylinder so as to feed the film. CONSTITUTION:The heat ray of the light from a lighting lamp 11 and a cold mirror 12 is absorbed by a heat ray absorbing filter 14, the luminous flux is stopped by a condenser lens 15 and the light passes through a color correction filter 16 and reaches a cylinder 17. Since the cylinder 17 is formed to be a cylinder having its axial line within a plane orthogonal to the light axis of the condenser lens 19, the light is converged to light the film 18 in a strip form. Sprockets 21a, 21b to feed the film vertically are provided to the cylinder 17 and the film 18 is wound and fed in the same direction as the rotation of the cylinder 17. Thus, the lighting to the film changes from the face to the strip, then the lighting optical system is made small in size and since the film face is adhered closely onto the cylinder, a picture with high quality is obtained.

Filed: 1990-05-31
Abstract: PURPOSE:To prevent a floating body jumping outside an air current even when the influence of ambient wind and the disturbance of an ascending current exist by providing a flexible ascent suppression member linking the floating body with a second fixed part so as to ascend up to a position lower than a first fixed part, and a flexible descent suppression member linking the floating body with the first fixed part so as to descend up to a position higher than the second fixed part. CONSTITUTION:When the ascending current is generated from the lower side of a supporting body 3 advancing upward by driving an ascending current generator 4, the ascending current is formed in laminar flow shape by being rectified by a wind arranging part 3b. The floating body 5 is ascended to the upper limit of the height of the ascent suppression member 6 by the ascending current formed in the laminar flow shape. However, since the floating body 5 is deformed by receiving the ascending current, and the ascending current is disarranged, the floating body 5 moves upward and downward between the descent suppression member 7 and the ascent suppression member 6. At this time, the floating body 5 is moved flying as if a butterfly is flying due to the elasticity of the floating body.

Title: Digital control type temperature compensating crystal oscillator
Inventor: TAKEUCHI TAKASHI
IPC: H03B5/32
Filed: 1987-06-04
Abstract: PURPOSE:To minimize a frequency change at the time of compensation by selecting the up-and-down counting and counting stopping condition of a counter by a size relation of the compensating data and the output of the counter in a detected temperature. CONSTITUTION:When a temperature detecting circuit 1 detects a temperature T1, an address 6 corresponding to T1 is outputted and compensating data DT1 in the T1 are outputted by a memory 2. When the temperature detected previously is T0, the compensating data in the T0 are DT0 and DT0<DT1 is obtained, an up-down control signal 17 comes to be the signal of the up-counting mode. When the number of the bits of the output of the memory 2 is M, the number of the bits of a counter 4 is L, M=L-2, DT0=DT1-1 is obtained and four clocks are inputted for the counter 4, an output comes to be equal to the compensating data DT1 and the signal 18 makes a counter action into a stopping mode. Even at the time of DT0>LT1, LT0=UT1, in the same way as the above- mentioned, signals 17 and 18 are set to a prescribed mode. Thus, the frequency change at the time of the compensation can be minimized.
