IPC: G01N29/26
Filed: 1982-12-24
Abstract: PURPOSE:To make it possible to detect flaws in a square steel piece and the surface layer of the side neighboring the incident surface thereof, by using an electronic scanning array type probe, fixing the probe at a specified angle with respect to the surface of the material at a remote position, inputting an ultrasonic wave beam at the central part of the incident surface, and performing electronic sector scanning. CONSTITUTION:In an electronic scanning array type probe, many vibrating elements 3 are aligned on the plane of a substrate 6 in one line. Coating 7 is applied on the surfaces of the elements. The control of an ultrasonic wave beam from the probe is performed by adjusting the timing of the sent and received waves of each element 3 by a delay time control circuit. The probe is set at the position, which is separated from the surface of the material by a specified distance in a vertical plane, so that the probe is inclined by an incident angle that is the center of the scanning deflection of a sector with respect to the incident angle. When the sector scan is made by the probe 1 comprising the total element number of 32, the probe 1 and a transmitting and receiving element 9 is connected by a delay circuit 9 in one to one correspondence. By sequentially changing the delay time setting by the delay circuit 9, the slant angle of the ultrasonic wave beam is changed, and the beam is swung. The scanning is performed in this way.

IPC: B60G17/08
Filed: 1991-08-21
Abstract: PURPOSE:To open and close a damping force adjusting valve only in the case where the piston speed is sufficiently small, in a damping force adjusting type hydraulic buffer. CONSTITUTION:A plunger 26 connected with a valve body 24 for opening and closing a bypass passage 23 is inserted into a diaphragm 31, and an air chamber 29 is formed on the inside of the diaphragm 31, and an oil liquid chamber 30 is formed on the outside.

Title: Picture signal processing method
Inventor: WATANABE RYOICHI
IPC: G06T1/00
Filed: 1985-10-19
Abstract: PURPOSE:To correct the two-dimensional shading of a picture at high accuracy by provisionally reading only a two-dimensional luminous energy distribution including only a light source without picture information to obtain reference data and correcting the main- and subscan directions of video data. CONSTITUTION:One-dimensional image sensor 104 scans a microfilm projection image 300 electrically in the main scan direction X and mechanically in the subscan direction. For each picture element unit from the sensor 104, sequentially video data is transmitted to a shading correction circuit 320 through an amplifier 310. After the corrected video data is binarized by a binarization circuit 340, other required processing is done through an interface circuit. First, reference data for two-dimensional shading is obtained, and then the gain of a D/A converter is adjusted by a correction coefficient corresponding to the reciprocal number of the reference data to correct the shading in the subscan direction. Moreover a picture signal is D/A-converted while an D/A converter executes the shading correction in the main scan direction with the aid of a reference signal.

Abstract: PURPOSE:To sense fluorescent light together with normal observation image in simple constitution by furnishing an illumination means, which can increase the light amount in that region among all wavelength regions of illumination light which is close to the exciting light for fluorescent agent, so as to be greater than the light amount in the other wavelength regions. CONSTITUTION:When monochronal antigen having accumulativeness for tumor identified with a fluorescent agent is given to a living body, this antigen is concentrated at the tumor. In case fluorescence is to be sensed through observation of the location inspected containing the fluorescent agent by the use of an electron endoscope 1, a lamp 21 is lighted pulsedly at the timing when filter elements of a rotary filter 30 are interposed on the illuminating optical path, and the light amount is increased only at the B timing compared with at the G and R timings. Accordingly the location to be inspected is irradiated in time series with the R, G, B lights having penetrated the rotary filter 30, wherein the amount of B light is greater than G and R. The beam from the location irradiated with this illumination light is received by a CCD 16, and thus a color image of the location inspected will be obtained.

Title: Power source circuit for empty weight meter of truck
Inventor: UCHIYAMA SHINKICHI
IPC: G01G19/12
Filed: 1982-12-31
Abstract: PURPOSE:To eliminate wasteful power consumption by providing a diode in the forward direction toward an output terminal of a power source stabilizing circuit, and providing a comparing means for turning off a switching element in case the voltage of a connecting point of each load is lower than the set voltage. CONSTITUTION:In case the voltage of a point P4 becomes lower than 5V, a comparator 63 generates an output. Therefore, since transistors 66, 67 are turned on and off, respectively, a current flowing through a coil 68 and the transistor 67 is disconnected as to its paths. During that time, energy is stored in the coil 68, and the moment the transistor 67 is turned off, it is brought to reflux to a power source through a diode 69 as a current. When the reflux current does not flow, the voltage of the point P4 rises and is stabilized to 5V which is set voltage. The reflux current flows to a load 41, therefore, an output current of a power source stabilizing circuit 50 is reduced by the reflux current portion.
