Title: Light element fluorescent x-ray spectroscope
Inventor: TSUNODA HIROSHI
IPC: G21K1/06
Filed: 1983-09-30
Abstract: PURPOSE:To remove secondary electrons and to improve S/N of a detection signal and the accuracy of analysis with a fluorescent X-ray spectroscope in which total reflection mirrors are used as a spectroscopic means and fluorescent X-rays of the wavelength having a specific value or above are totally reflected by impressing a magnetic field roughly perpendicularly to the fluorescent X-rays incident on the mirrors. CONSTITUTION:Secondary electrons in addition to fluorescent X-rays are generated from a sample excited by X-rays. Since the incident angle of the fluorescent X-rays to mirrors 4 is low, the angle at which the route of the fluorescent X-rays are bent in the midway is small and therefore the probability that the secondary electrons past slits 3 enter a detector 5 is extremely high. Magnetic poles 8, 9 are for shutting off these secondary electrons and generate the magnetic field crossing roughly perpendicularly with the route for the fluorescent X-rays by a U-shaped permanent magnet or electromagnet 10. The magnetic field bends the route for ahe secondary electrons withdout affecting the fluorescent X-rays thereby separating the secondary electrons from the fluorescent X- rays and preventing the secondary electrons from entering the detector 5.

Title: Measuring method of insulation resistance excluding influence of earth resistance
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1984-09-03
Abstract: PURPOSE:To measure accurate insulation resistance by applying a rectangular wave signal which contains higher harmonic components to a cable way and detecting a leak current fed back to an earth wire. CONSTITUTION:The output of a rectangular wave oscillator OSC2 of frequency f1 is applied to cable ways L1 and L2 through the earth wire LE and the leak current circulating through the earth wire L is detected by a zero-phase current transformer ZCT. Its detection output is branched to BPF2 and BPF3 and the output of BPF3 is led to and modulated by a modulator with the frequency 4f1 of the 4th higher harmonic component of the oscillator OSC2 and then applied to LPF to obtain 4f1-3f1=f1; and its output is applied to one input of an adder ADD. The output of BPF2 which passes a signal of f1 selectively, on the other hand, is applied to the other input terminal of the adder ADD through an amplifier AMP. The output of the adder ADD is applied to a synchronous detecting circuit MULT2 for effective component detection and the basic frequency signal f1 of the oscillator OSC2 is used as a synchronizing signal to obtain an applied voltage and an in-phase component. Therefore, a signal which is in inverse proportion to the insulation resistance of the cables way appears at an output OUT.

IPC: G03B27/62
Filed: 1980-12-25
Abstract: PURPOSE:To improve the workability of an original for placing an original on a table by driving a feeding mechanism interlocking with opening and closing movements of an original press-contacting plate to the original imposing plate. CONSTITUTION:On the condition that an original press-contacting plate 4 is closed, an opening movement A is applied to the plate 4 with a shaft 3 as the center by the gripped handle part 41. An original feeding shaft 9 is driven for turning clockwise through gears 8 and 11 interlocked with this, but as a clutch 13 is set to the idle turning direction against the original feeding roller 12, each roller 12 is not driven for turning. And it fully opens the plate 4 and removes a copied original. Then, when closing turn B is applied to the plate 4, the shaft 9 is driven for turning counterclockwise. As this turning direction is that for the clutch 13 to work, each roller 12 and the shaft 9 are driven for turning as one unit, and the direction is that of sending the original from a cassette's side 14 to the table for the original, and therefore, the original is automatically sent out.

Title: Sorter of kneaded material
Inventor: MORIYAMA MASAO
IPC: B29B7/28
Filed: 1990-07-11
Abstract: PURPOSE:To sort the kneaded material without disturbing a producing line and to enhance the quality of a molded form by equipping a top-opened type vessel housing the kneaded material just under the discharge port of a bath type kneader and providing a vessel transferring mechanism for displacing this vessel, a weighing machine of the kneaded material in the vessel and a controlling mechanism thereof. CONSTITUTION:When kneaded material is introduced into a vessel 27 from a closed type kneader in the upper part and this introduction is detected by a sensor, a main driving gear 38 of a weighing controlling mechanism 30 starts rotation to raise a weighing machine 34 and also the vessel 27 is raised and weighing is performed. A controlling part previously memorizes the total weight of a raw material introduced into the kneader. The controlling part judges whether the weighing value of a sorter is present in a prescribed allowable range in comparison with the memorized data. When the controlling part judges the said weighing value as normal value, the motor 16 of a driving source of a vessel transferring mechanism is normally rotated and the kneaded material in the vessel 27 is transferred to a normal stage. When it judges it as abnormal, the motor 16 is reversely rotated and the kneaded material in the vessel 27 is allowed to fall on the different conveyor from the normal case.

Abstract: PURPOSE: To emit a spot light to an object in fully automatically by forming the system of the spot light with a television camera, a spot light, a control circuit, a driving circuit and an optical transmitter to drive the spot light integrated with the television camera. CONSTITUTION: A television camera 4 is arranged aside and close to a remote control spot light 7 fitted above a stage 1 at a short distance, and picks up an upper part of the stage 1 to receive an image. A control circuit 5 identifies and extracts a color and a pattern of closing of a person 2 to whom a spot light is desired to be projected based on an image reception signal. When the person 2 carries an optical transmitter 3, the control circuit 5 identifies and extracts the optical signal from the transmitter 3. Then the control circuit 6 provides an output of a horizontal signal and a vertical signal to a driving circuit 6 so that the extract signal comes to a center or at a prescribed position of an image pattern from which other signals than the extract signal are eliminated.  The driving circuit 6 drives a motor to drive the spot light 7 moving integral with the television camera in vertical and horizontal directions. Thus, even when the object person 2 is moving, the spot light emits a light to the object person at all times.

Title: Display apparatus of vehicle charger
Inventor: KUNO HIROMICHI
IPC: H02J7/02
Filed: 1993-07-27
Abstract: PURPOSE:To protect an auxiliary battery from total discharge caused by the power consumption of a charging finish state display by a method wherein the LED display showing the charging finish state is continued for a required time only. CONSTITUTION:When the charging of a main battery 10 by a charger 12 is finished normally, an LED 32 is turned on and, when it is finished abnormally, an LED 34 is turned on. A control part 14 starts counting by a lamp counter and, when the counted value of the counter exceeds a predetermined value, the display by the LED 32 or 34 is turned off. After that, if an IG switch is turned on by a user, the control part 14 turns on the LED 32 or the LED 34 on a display operation panel 16 selectively in accordance with the charging finish state. As the display is performed in accordance with a sequence, it is performed at the first turning-on of the IG switch only after the charging finish. Therefore, a power consumption caused by the continuation of the display of the LED 32 or the LED 34 is not produced, so that the total discharge of an auxiliary battery 18 which supplies a power to the display operation panel 16, etc., can be avoided.
