Title: Antenna for insulation-abnormality monitoring device for electric apparatus and insulation-abnormality monitoring device for electric apparatus
Inventor: HORIKOSHI KAZUHIKO
IPC: G01R31/12
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To obtain an antenna which is used for an insulation-abnormality monitoring device, which can keep the insulation of an insulator, whose detection sensitivity can be improved and which can be used also as an accumulation-of-snow preventive structure. SOLUTION: Every antenna 4 is provided with a conical trapezoidal trunk part which is formed of a metal plate and which covers the whole circumference of an insulator mounting part, with a flat part which covers the upper part of the insulator monitoring part over the whole circumference and with a fixation part which is used to attach an insulator 14 to the mounting part. A slit is formed in a part of the trunk part, and every antenna 4 is constituted. Every antenna 4 is fixed to an insulator mounting part at an electric apparatus 10 so as to cover the stepped part of the mounting part. Thereby, it is possible to prevent snow from being accumulated on the insulator mounting part. In addition, since the shape of every antenna 4 becomes large, the detection sensitivity of electromagnetic waves is enhanced.  In addition, since an outward form is formed of a smooth face, it functions as the shield of the insulator mounting part.

Abstract: PURPOSE:To prevent the unautorized use of an electronic equipment or an image forming device by providing a means by which whether or not an image input device has a special function can be anthenticated by means of the electronic equipment as to the image input device. CONSTITUTION:A CPU 450 at an image scanner 2201 side generates a random number RM, calculates X=Rm<2> modn and transmits it to the CPU 460 of a printer 2202. The CPU 460 stores the received X data in an internal RAM and generates the random number Bm. The CPU 450 transmitting Bm data to the image scanner side transmits Y=Rm data to the printer 2202 side when the value of the received Bm is zero and transmits the value of Y=TRmmodn to the printer when the Bm value is one. The CPU 460 which receives the Y data checks the validity of the Y value. Then, when the received Y data is judged to be valid, image data is transferred. If the Y data is invalid, the CPU 450 is stopped.

Title: Device for detecting abnormality on surface of wire body
Inventor: HIRAI TAKESHI
IPC: G01N21/952
Filed: 1983-01-13
Abstract: PURPOSE:To ensure the detection of an abnormal part on the entire surface of a wire body, by emitting light from a light emitting source, which is revolved around the wire body with the wire body as a center, reflecting the light from the surface of the wire body, and receiving the reflected light by a light sensor. CONSTITUTION:When the cross section of a wire body 1 is true circle, light inputted from a light emitting source 2 at an incident angle alpha is reflected at an incident point P on the surface of the wire body at a reflecting angle alpha. The reflected light is received by a light sensor array 3. Meanwhile, when, e.g., a protruded abnormal part E is located on the wire body 1, the light from the light emitting source 2 is reflected at an angle different from the specified reflecting angle alpha and is not received by the light sensor 3. Therefore, when the amount of the light received by the light sensor 3 is analyzed, detection of abnormality on the surface of the wire body can be ensured. When an expression T<=l/L is established, where the speed of the wire body is Lm/sec, the effective length of the light emitting source is lm, and T is a time in second, during which the light emitting source 2 and the light sensor 3 revolve once, the entire surface of the wire body is scanned. Thus, the detection of the abnormal part on the entire surface of the wire body can be ensured.

The pressure fluctuation accompanying the Karman vortex is introduced into an eddy detecting body on the downstream side for acting upon a diaphragm, and detected with a distortion gage. The pressure fluctuation corresponds to eddy frequency, that is, wind speed.  The pulse signal obtained with an eddy detection circuit is counted by a counter of the calculating part B, and the counted value is processed by a wind direction calculating part and a wind speed calculation part, respectively, and sent to a display part for displaying a wind speed value and wind direction.

Abstract: PURPOSE: To make possible forming the hologram reconstructed images having been recorded on plural different concentrical circumferences in the same position by moving a recording object in the direction perpendicular to the optical axis of a recording optical system including an imaging lens and performing hologram recording.  
     CONSTITUTION: The radiated light of an object 61 by the coherent laser beam through a random phase plate 5 goes through the recording optical path including an imaging lens 7, etc. and images on a hologram recording plate 9, whereby the hologram of the object 61 is formed on the recording plate 9 by way of reference light 10.

Abstract: PURPOSE:To reduce two kinds of misconvergence at the same time with a pair of auxiliary coils, and to restrict the power consumption by arranging a rotatable magnet between a pair of auxiliary coils, and providing a movable magnetic body outside thereof. CONSTITUTION:A pair of auxiliary coils 1a, 1b respectively have a magnetic core 2, and a rotatable circular magnet 3 is arranged between the coils 1a, 1b, and this combination structure is surrounded with a movable cylinder 4 made of magnetic body. In the case of reducing the misconvergence, when the cylinder 4 is moved left, inductance of the coil 1a is increased to make the current hard to be flown, and inductance of the coil 1b is lowered to make the current easy to be flown. Current flowing in a horizontal deflecting coil 14b is therefor larger than the current flowing in a horizontal deflecting coil 14a, and the magnetic beam generated by the lower coil 14b is stronger than that of the coil 14a. Two kinds of misconvergence can be reduced at the same time by a pair of auxiliary coils through the rotatable magnet 3 and the movable cylinder 4.

IPC: G01R29/04
Filed: 1978-01-19
Abstract: PURPOSE: To judge the waveform such as vibrations of the object being measured easily, by corresponding the counting of a first counter circuit to the peak value of waveform signal of the object being measured, and the output of a second counter circuit to the period of the waveform signal.  
     CONSTITUTION: The waveform signal from a vibrometer 1 to measure the vibrations of the object being measured, for instance, a bearing, is amplified and relieved of high frequency components, and then inputted into a delay circuit 4 and an effective value circuit 5. If the level of the waveform signal detected taking this effective value as the threshold level exceeds the set threshold level, a pulse signal is emitted from a comparator 6. A counter 11, taking this signal and the pulses of an oscillator 7 as the input signals, outputs the measured value corresponding to the peak value of the waveform signal of the object being measured. A counter 12, taking inputs through a flip-flop 9, outputs the measured value corresponding to the period of the waveform signal. Thus, the peak value and the period of the waveform signal may be easily discriminated in a judging device 13.

Abstract: PURPOSE:To eliminate the variance of density of lit picture elements and to raise sufficiently a contrast ratio of lit picture elements to non-lit ones by driv ing a liquid crystal display device with <=8 and >=5 bias ratio. CONSTITUTION:A controller 1 stores display data inputted from a CPU in a storage device 3 and reads out this data and transfers a control signal and display data to a scanning-side driver 4 and a signal-side driver 5 respectively. Drivers 4 and 5 select bias voltage levels from a liquid crystal driving voltage generating circuit 6 and apply them to electrodes of a liquid crystal display device 7. If the duty cycle is set to >=100 and the bias ratio is set to <=8 and >=5, an initial peak voltage impressed to non-lit picture elements is reduced to increase the difference between effective voltages of lit and non-lit picture elements. Thus, the variance of density of lit picture elements and blur of non-lit picture elements are eliminated to raise the contrast ratio of lit picture elements to non-lit those.
