Title: Pit detector for pipeline
Inventor: ANDO SEIGO
IPC: G01N27/90
Filed: 1985-03-29
Abstract: PURPOSE:To enable automatic removal of various noise voltages generated during the inspection and initial unbalance voltages of respective probe coils during the operation of a sensor, by measuring relative distance based on arithmetic mean obtained with an automatic balancing circuit at each of the probe coils to apply the voltage involved in the measurement of the relative distance to a differential amplifier. CONSTITUTION:When a head 1 moves in the direction of the arrow and reach any pit 14a on the internal wall of a pipe body 14, the distribution phi of mag netic flux in th perimeter of the pit 14a is disturbed and the induced voltage in the probe coil S1 alone corresponding to the pit 14a will change and reduce as compared with other probe coils S2-S-N. The probe coils S2-SN are con nected to a multiplexer 3 with which the induced voltage in the respective probe coils S1-SN is extracted in time division. The signals thus extracted are applied to a detector 9 via a noise filter 8, where the signals are detected synchronously by a reference voltage of an oscillator 2, converted into a DC voltage and then, applied to a differential amplifier 10 and an automatic balanc ing circuit 11. Thus, a flaw signal due to the pit 14a is generated at the output terminal of the differential amplifier 10.

Title: Character segmenting method for character reader
Inventor: SHIMOYAMA ATSUSHI
IPC: G06K9/34
Filed: 1990-03-14
Abstract: PURPOSE:To enable character segmentation by using a normal medium by reading a slip, setting the positions of a reference character area and an objective character area, storing these positions into a memory and correcting the position of the read character area with these set positions as references. CONSTITUTION:An MPU 4 reads the slip to be used, extracts the character area, sets the positions of the reference character area and the objective character area and stores them into as memory 5 as format information. The MPU 4 reads out the format information from the memory 5. Next, the slip is read and a character area extraction program 7a is executed so as to detect the position of the reference character area. Then, a correct value extraction program 7c is executed so as to calculate error to a format reference position and to extract a correct value. The MPU 4 executes a character position correction program 7d and according to this correct value, the respective character area positions of the format are corrected. By using the objective area position, the character area is segmented from the picture data of a picture memory 3.

Filed: 1984-03-31
Abstract: PURPOSE:To discriminate the tape recording speed by monitoring the waveform of subtraction output of the reproducton information on two pilot signals to be reproduced with the rotary magnetic heads having the same azimuth. CONSTITUTION:A tape start signal Sa which shows whether the tape driving speed is set at a fixed level or not is supplied to a control circuit 31 together with a repoduction presence/absence signal Sb which shows the presence or absence of a reproduction signal.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a camera controller that can display a picture with high quality at a high frame rate. SOLUTION: A controller for a CCD camera 15 photographing a picture to be sent through a communication channel is provided with a camera device driver 12 that reads charges of a CCD generated for an exposure time under its control, an image compression driver 13 that compresses the image by generating image information on the basis of data read from the CCD, a communication driver 14 that transmits the compressed image information through a communication channel, and a control arithmetic means 11 that sets an exposure time of the CCD on the basis of a luminance of an object acquired from the camera device driver and controls number of times of generation of the compressed image information by the image compression driver on the basis of this exposure time, the communication capacity of the communication channel and the image information size.  Thus, interleaving of compressed image information can be controlled by taking both the exposure time of the CCD camera and the communication capacity of the communication channel into consideration.

Title: Timing margin test device for interface signal
Inventor: TAKAI KENICHI
IPC: G06F11/24
Filed: 1989-03-17
Abstract: PURPOSE:To easily obtain both the phase leading and lagging limit values by using a means to produce an optional phase lagging time to an optional selected single or optional plural selected signals. CONSTITUTION:A test circuit 2 is stored in an independent housing containing a control panel, and a delay circuit 6 consisting of the programmable delay lines 26 and 27 and a counter 28 is prepared to each signal. The general operation of the circuit 2 and the control panel is carried out by a microprocessor 7 via a program process. Thus no operation is required for a device to be tested and a phase leading time can be applied to an optional signal by giving an equal phase lagging time to all signals. As a result, an interface is secured between the circuit 6 and the microcomputer 7 and therefore a phase lagging time can be set via a program process. Thus it is possible to obtain an abnormality detecting function related to an interface signal that can perform a highly effective test with a simple operation.

Abstract: PURPOSE:To check the hardening of a copper sphere formed by melting and to prevent the breakdown, deformation, crack, etc., of a pellet, an electrode pad and the like, by keeping the fore end portion of a slender copper wire in an atmosphere of high temperature from a time just before the formation of the copper sphere to the completion of bonding. CONSTITUTION:The fore end of a slender copper wire 15 fed from a wire feeding mechanism 6 and inserted through a capillary 4 is heated to be melted, so as to be formed into a copper sphere 15a. Inactive gas is heated by a heater 18 from a time just before the formation of the copper sphere 15a, and thereby the portion near the fore end of the slender copper wire 15 is kept at a high temperature. The copper sphere 15a continues to be kept at the high temperature after the formation thereof also until bonding is ended. Thereby the copper sphere 15a is checked from hardening due to cooling. When the copper sphere 15a is pressed against an electrode pad of a pellet 10 by the fore end 4a of the capillary 4, accordingly, the copper sphere 15a is so crushed as to be fit with the electrode pad, since the difference in hardness from the electrode pad of aluminum is lessened. Therefore the breakdown or deformation of the electrode pad is eliminated, and no crack 17 occurs.
