Abstract: PURPOSE:To obtain a low-pressure discharge lamp with a long life and high efficiency by using hot cathodes holding an electron emitting material on the surface of a metal plate or at least between two plates, and connecting only one end of the hot cathodes to lead wires. CONSTITUTION:Hot cathodes 1, 2 are sealed at both ends of a straight tube- shaped discharge container 4 with a phosphor film 3 on the inner face, and the hot cathodes 1, 2 are connected to single lead wires 5, 6 respectively.

Title: Wheel alignment measurement for automobile
Inventor: YAMANAKA NAOHARU
IPC: G01M17/007
Filed: 1986-07-02
Abstract: PURPOSE:To enable non-contact measurement of wheel alignment at a high accuracy, by irradiating a load wheel with at least three beams of slit light to detect the positions of images of the slit light within the images taken by means of two cameras. CONSTITUTION:Slit light beams S1-S3 are projected to a load wheel H from three projectors and a tire T is taken by means of two cameras to obtain images (A) and (B). Then, the positions of intersections a1-c1 and a2-c2 are determined between the peripheral circle R of a rim of the wheel H and images of the beams S1-S3 within the respective images. A spatial coordinates of a point A (intersection between circle R and beam S1) on the wheel H are obtained by a technique of trigonometrical survey based on the known layout relationship between the two cameras and positional information on the points a1 and 2. Likewise, spatial coordinates of the points B and C are obtained. This determines one plane containing the points A-C thereby enabling the detection of an angle between the inclination of the plane and the axis of ongoing direction of a vehicle and a vertical axis, namely, toe- and camber angles.

IPC: H04N5/93
Filed: 1978-12-14
Abstract: PURPOSE: To increase the S/N without impairing both the horizontal and vertical resolution by giving the amplitude limit to the difference component between the output obtained by delaying the TV signal for one horizontal scanning period and the signal with no delay given and then subtracting the output from the TV signal.  
     CONSTITUTION: The TV signal is supplied to delay circuit 2w from input terminal 1 to be delayed for one horizontal scanning period, and the delay output and the TV signal input undergo the subtraction through subtractor circuit 3 to extract the difference component. The function of the output of circuit 3 forms the comb-line filter to the function (A) of the frequency of the supplied TV signal. For the output of circuit 3, the components of over the fixed level are extracted through amplitude limit circuit 4 and then applied to subtractor circuit 5 to receive the subtraction in the form of the difference component from the TV signal. For signal (C) obtained  at output terminal 6, the noise component of a low level is negated completely.  However, the larger level one among the edge parts of the TV signals is not negated, thus causing no reduction of the resolution.

Abstract: PURPOSE: To provide a device for treating radioactive gas waste, which has a drier capable of continuously dehumidifying exhaust gas at zero point below freezing point without necessity of alternatively switching operations.  
     CONSTITUTION: Gas reached through exhaust gas recoupler and condenser first stage compressor 11 is stored within a pressure vessel 12 at the pressure higher than atmospheric pressure, and cooled by a cooling type drier 14 so that moisture in the exhaust gas does not freeze to be then fed to second stage compressor 15. The gas thus compressed by the compressor 15 is cooled by a cooling type drier to be dehumidified without freezing. Since this gas is considerably high pressure, it is frozen, if it is abruptly lowered to the atmospheric pressure, at pressure reducing valves 20, 22, 24. Accordingly, the valves 20, 22, 24 and activated charcoal hold-up towers 19, 21, 23, 25 are alternatively installed to allow the exhaust gas lowered at temperature upon throttling and expanding via the pressure reducing valves to be cooled by the activated charcoal in the tower to thus gradually reduce the pressure and to be introduced into a stack 26.

Abstract: PURPOSE:To easily form an image with a smooth gradation even if the rate of the change in the gradation is small by outputting an arbitrary image element which is near a changing point where the value of output data is changed in the way that the image element has data the same as the output data on an image element which is near the changing point and is on the opposite side of the image element. CONSTITUTION:An image signal 14 which responds to a gradation pattern sent from a scanner main body is compared with a screen pattern memory 12 by a comparator 16, and output data which decides the size of each image element in response to the size of each image signal 14 is outputted. Then, the stepped difference of part is falsely lessened by outputting the arbitrary image element which is near the changing point where the value of the output data is changed in the way that the image element has data the same as the output data on the image element which is near the changing point and is on the opposite side of the image element. Thus, a gradation pattern the stepped difference of which can't be identified by a naked-eye can be formed even if the rate of the change in the gradation is small.
