Title: Ultrasonic observing device
Inventor: FUJIMOTO HIROSHI
IPC: G01N29/22
Filed: 1989-04-27
Abstract: PURPOSE:To reduce a noise by using a cable to be temporarily made unnecessary for obtaining an ultrasonic image and executing differential reception to the noise received with the cable and a reception signal, which receives the noise. CONSTITUTION:When a high frequency scalpel 5 is used, the noise is induced to co-axial cables 10, 11 and 12. When a vibrator 8 of 7.5MHz is used, the noise induced by the high frequency scalpel is superimposed to a reception echo signal (A) inputted to a pre-amplifier 13. In the input signal (B) of a pre- amplifier 14, only the noise induced by the high frequency scalpel 5 appears. The two signals (A) and (B) pass through the pre-amplifiers 13 and 14 of a wholly equal characteristic and afterwards, the signals are inputted to a differential amplifier 16. Then, only the echo signal of no induced noise appears in the output of this differential amplifier 16. The output signal of this differential amplifier 16 is frequency-detected by a frequency detecting circuit 18, converted to a digital signal by an A/D converter 19 and written to a DSC 20. Then, the ultrasonic image is read from this DSC 20 as a video signal and the ultrasonic image of the low noise is displayed on a monitor 3.

Abstract: PROBLEM TO BE SOLVED: To suitably keep the air gap between a cylinder and tape to prevent a tape from damage by changing/indicating so as to increase the speed of the cylinder when the speed from reel speed setting is the same or faster to or than the speed from cylinder speed setting in comparison with both cylinder speed setting and reel speed setting. SOLUTION: A speed command is given to a cylinder driving means 2 with a cylinder speed setting means 1 based on a rewinding command to rotate the cylinder 3. The outer circumferential speed of the cylinder and the winding speed of the tape are calculated/compared from the speed set in the cylinder 3 and the speed set in the reel 6 with a comparator 7.

Title: Semiconductor device and manufacture thereof
Inventor: YOSHIHISA YASUKI
IPC: H01L31/10
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent irregular reflection of the incident light rays projected upon a photodiode by removing recessed sections formed on the main surface of a semiconductor layer in a photodiode forming region, by reducing the thickness of the semiconductor layer while part of the recessed sections is left on the main surface of the semiconductor layer in an alignment mark forming region. SOLUTION: Recessed alignment marks are formed for making the position of an n-type buried region accurately identifiable on the p-type silicon substrate of a semiconductor device after an n-type epitaxial layer is grown on the substrate. While recessed sections are left on the upper surface of the n-type epitaxial layer in an alignment mark forming region 3, the recessed sections formed on the upper surface of the n-type epitaxial layer in a photodiode forming region 2 are removed by reducing the thickness of the n-type epitaxial layer by polishing. Since the surface of the epitaxial layer in the photodiode forming area 2 is flat, the random reflection of the incident light rays projected upon photodiodes 4a-4d can be prevented and the occurrence of input sensitivity variation among the photodiodes can be avoided.

Title: Detector for rotative angular velocity of optical fiber
Inventor: OOKI NAGAMITSU
IPC: G01C19/00
Filed: 1984-05-29
Abstract: PURPOSE:To improve the temperature characteristic by winding optical fibers around plural bobbins different in coefficient of thermal expansion in the device which uses the Sagunac effect to detect a rotative angular velocity on a basis of the difference of propagation time between a clockwise light and a counterclockwise light. CONSTITUTION:The light emitted from a light source 1 is divided into two, namely, the clockwise light and the counterclockwise by a half mirror 2. These lights are inputted to an optical frequency converter 5 through optical fibers 3 and 4. The clockwise light and the counterclockwise light which are converted by the optical frequency converter 5 and are propagated round in directions opposite to each other are synthesized by the mirror 2 again and are received by a photodetector 6. Bobbins 7 and 8 of optical fibers 3 and 4 are formed with materials different in coefficient of thermal expansion, for example, quartz and stainless steel. A rotative angular velocity detector is installed in a system to be measured, and the frequency is converted by the converter 5 so that the output signal of the photodetector 6 is constant, and the angular velocity is detected. Consequently, influences of temperature upon optical fibers are eliminated to detect the rotative angular velocity with a high accuracy because bobbins of optical fiber rings are made different in coefficient of thermal expansion from each other.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an abnormal amplitude reference as a result of adaptation, in the case of employing the Viterbi decoding method by which the amplitude reference is subjected to adaptive processing. SOLUTION: This device controls the adaptive operation, so that the processing is started after a PLL has been locked to prevent the effect of a clock phase error that is one cause of occurrence of an abnormal amplitude reference onto the adaptive processing. Specifically, a register 102 generates an AGATE signal that is made active after the lapse of a prescribed time, when a read gate is activated. Then an RAA 101 starts adaptive processing, when the AGATE signal is activated. The prescribed time in this case is set by adding a margin to a degree for a required time until a lock of the PLL is finished.
