Title: Position correction and adjustment system for input original
Inventor: TSUKAMOTO SETSUO
IPC: H04N1/387
Filed: 1990-03-13
Abstract: PURPOSE:To correct and adjust the position of image information to a prescribed position regardless of deviation of an original at the input by moving the image information read in response to the position information of the original detected when the original is read by a read means to the prescribed position on the original. CONSTITUTION:When an original is read from a scanner 1, a coordinate of one corner of an original is detected simultaneously as its input and the position information is given to an image processor 2 together with the image information of the original. The image processor 2 uses a position calculation section 13 to calculate the position of the input original based on the corner coordinate of the received position information together with the image information, and in order to move the image information of the original to the calculated correct position for the input original, how much the information is to be moved vertically or horizontally is calculated and the result of calculation is outputted. A position moving section 14 based on the result of calculation from the position calculation section 13 converts the image information for the movement on the original pattern. Thus, the position of the image information is corrected and adjusted to a prescribed position.

IPC: H04N13/00
Filed: 1987-03-18
Abstract: PURPOSE:To discriminate and reproduce a duplex recorded track by recording video signals for right eye and those for left eye in duplex recording tracks adjacent to each other, and multiplex recording the track discrimination signals on at least either of the said recording tracks. CONSTITUTION:In a video disk record in which recording is formed simultaneously on two adjacent sprial or concentric recording tracks, a discrimination code is added on one and the same line while following a control code signal.

Title: Altitude measuring instrument for pipe line
Inventor: HAMADA SEIJI
IPC: G01C5/04
Filed: 1990-03-14
Abstract: PURPOSE:To easily and accurately detect the altitude of even the pipe line in a complicately buried state by applying static hydraulic pressure to a hose inserted into the pipe line from a liquid tank while the tip of the hose is closed, and detecting pressure applied to liquid by a pressure sensor atop of the hose. CONSTITUTION:However the pipe line 2 is bent up or down, or right or left in the ground, the liquid 13 in the liquid tank 12 does not flow out in the hose 7 whose tip is closed at all times, so the pressure sensor 17 outputs a signal corresponding to the altitude accurately. Further, even if the tip 7a of the hose 7 is higher than the liquid level in the liquid tank 12, its altitude can be measured within the range wherein the liquid 13 put in the host 7 does not overflow. In this case, the sensor 17 detects negative pressure. For the purpose, the sensor 17 which generates the output signal corresponding to the altitude even for the negative pressure is selected in this case. Then none of the liquid 13 flows out of the tip of the hose 7 and the altitude of even the pipe line in the complicate buried state can accurately and easily be measured.

Title: Toner concentration controller
Inventor: MIYAZAKI YOSHIFUMI
IPC: G03G15/08
Filed: 1986-03-20
Abstract: PURPOSE:To easily set toner concentration initially by providing a varying means for varying the oscillation start period of a piezoelectric element depending upon the quantity of contacting of a developer. CONSTITUTION:The piezoelectric element 28, an oscillation circuit 40, and a variable resistor 42 constitute an oscillator 44 which begins to oscillate when the developer in a developer chamber becomes less than at the time of initial setting, i.e. when the toner concentration decreases. Here, the input resistance of the oscillator 44 is varied by the variable resistor 42 to set the start period of oscillation, i.e. oscillation sensitivity. Consequently, a developer whose toner concentration is know severely need not be put in at the time of the initial setting and there is no need for skillfulness for the initial setting of the toner concentration. Consequently, even a beginner can set the toner concentration initially and the operation time of the initial setting is shortened greatly.

Title: Control of induction motor
Inventor: OKAMATSU SHIGETOSHI
IPC: H02P27/06
Filed: 1978-05-30
Abstract: PURPOSE: To permit the exact control of current even during high-speed operation by changing slip frequency when current command for controlling the current of induction motor is changed.  
     CONSTITUTION: When starting power running, the slip frequency SP is risen up at a definite time constant by closing the contacts P and ON, and when stopping command for power running is sent out, the slip frequency command SP is trailed down at a definite time constant by opening the contact ON and also by closing the contact OFF. Furthermore, when switching the power regeneration, the contact P is opened and the contact B is closed to inverse the polarity of output terminal and when starting regeneration, the contact ON is closed to trail SP. And, when stopping regeneration command, the contact ON is opened and the contact OFF is closed to rise up SP to zero level. Thus, even when inverter is operated at high frequency, the current of induction motor can be exactly controlled and also driving or braking force can be smoothly controlled over the full speed range of induction motor.
