Title: Frequency selection characteristic measurement for video intermediate frequency circuit
Inventor: TAKAHASHI AKIRA
IPC: H04N17/04
Filed: 1987-10-29
Abstract: PURPOSE:To measure a video intermediate frequency selection characteristic alone by a method wherein a DC voltage is applied to a frequency control terminal of a VCO to release a synchronous bondage thereof and the VCO is forced so that an oscillation frequency thereof is such near a chroma signal. CONSTITUTION:When a PIF signal is swept by a sweep generator 5 to be inputted into a PIF frequency selection circuit 1, the PIF sweep signal is applied to a complete synchronous detection circuit 42 through the PIF frequency selection circuit 1 and an amplification circuit 41. But when a DC voltage of 0-9V is applied to a frequency control terminal 3 of the VCO3 from a power source 11, synchronous bondage of the VCO3 is released while an oscillation frequency of the VCO3 can be changed. This enables measurement of a video intermediate frequency selection characteristic alone when a frequency selection characteristic is measured by an output of a video circuit.

IPC: H04N5/21
Filed: 1989-10-20
Abstract: PURPOSE:To remove noise regardless of a moving image part and a still picture part by providing an isolated point removing filter, to which a difference signal between a delay video signal and a video signal is inputted, and an adder to calculate difference between the difference signal and the output signal of the isolated point filter. CONSTITUTION:The difference signal between the video signal from a signal delay circuit 3 and the video signal to remove the noise is inputted to an isolated point filter 5. The isolated point filter 5 removes the noise of the inputted difference signal and an adder 6 calculates the difference between the difference signal and the output signal of the isolated point filter 5 and takes out the noise. By using this taken-out noise, the video signal removing the noise is outputted and applied to the signal delay circuit 3. Thus, the noise can be removed in the moving image part, where the change amount of the video signal is large, and the picture quality of a display picture is prevented from being lowered by double image interference. Further, the noise of the composite video signal can be removed as well.

Title: Method of detecting positional shift of tunnel excavator
Inventor: TAKAHASHI NORIO
IPC: E21D9/06
Filed: 1991-09-27
Abstract: PURPOSE:To precisely compensate the position of an excavator by setting positional shift adjusting values with respect to a planned line, at predetermined intervals during a pilot head is pushed, and compensating the positional shift when it exceeds the such a value after the excavation is made by a predetermined distance. CONSTITUTION:A pilot pipe 6 is connected to a pilot head 4 having a cutter and is pushed by a propulsion jack 5. A positional shift of the head 4 with respect to a planned line is measured with the use of a laser or the like, and excavation is carried out while the positional shift is corrected. During excavation, positional shift adjusting values with respect to the planned line are set at predetermined intervals in accordance with a predetermined expression formula. Whether or not the positional shift after excavation by a predetermined distance is below the associated positional shift adjusting value is determined. If it exceeds the value, it is determined that the position of the measuring unit such as the laser or the like is deflected, and a true shift value is corrected in accordance with a difference between the measured positional shift value and the positional shift value, and is displayed. Accordingly, it is possible to prevent a buried pipe or the like from being largely shift from the planned line.

Title: Signal delay circuit
Inventor: HIRANO YOSHIFUMI
IPC: H03K5/13
Filed: 1987-10-30
Abstract: PURPOSE:To prevent the variance of a delay time by using one terminal of a resistor as an input terminal and using the other terminal as an output terminal, connecting a capacitor to the output terminal, connecting a constant current source circuit to the other terminal of the capacitor and increasing the product between the resistance and the capacitance more than the time desired to be retarded. CONSTITUTION:An input waveform 101 is charged in a capacitor 2 through a constant current source 3 at the leading period 103. In this case, an output voltage 102 is the subtraction of (current [A] of constant current source)X(resistance [OMEGA]) from an instantaneous value at input terminal [V]). Then the charge in the capacitor 2 is discharged at the trailing period 104. Thus, the delay time 105 when the input waveform rises is a value being the result of division of (current [A] of current source)X(resistance [OMEGA]) by the leading time [V/sec] of the input signal. Thus, the resistor, capacitor and current source are used in this way then the delay time depends on the dispersion in the resistance and the current source and independent of the dispersion in the capacitance.

Title: Close-contact type image sensor
Inventor: HIGUCHI TERUYUKI
IPC: H04N1/19
Filed: 1988-10-31
Abstract: PURPOSE:To read out only the character symbols of desired colors by performing the switch between the LEDs having different peak light emission wavelengths. CONSTITUTION:A lens array 2 contains many refractive index distribution type fiber lenses and forms an erecting lifesize image of a reading form 5 on the photoelectric conversion surface of a 1-dimensional image sensor 1. Then the image formed on the photoelectric conversion surface is converted into the electric signals by the sensor 1. A red LED array 4 has its peak wavelength approximate to 660nm and serves as a red light source to reflect satisfactorily the reddish colors. In other words, a red color is defined as a drop-out color. In such a way, two LEDs having different peak light emission wavelengths are switched with each other. That is, the yellow and green colors are dropped out and the print of a red color is read when a yellow/green LED array 3 is turned on. Then the print of a red color is dropped out when the array 4 is turned on. For instance, it is possible to read the red seal impressions, etc., while dropping out the red character entry frames via an optical character reader.
