Title: Angle beam ultrasonic flaw inspection
Inventor: TAKEGAWA TETSUYA
IPC: G01N29/11
Filed: 1982-09-08
Abstract: PURPOSE:To achieve an accurate flaw inspection at a hard to detect point such as special material welded joint by a method wherein an ultrasonic wave slantly incoming on metal material and echoes are combined as emergizing corresponding to conditions of defects with a path analysis of various reflected echoes including those returning following a mode conversion. CONSTITUTION:When ultrasonic waves slantly incoming on material, a part thereof is returned directly being reflected on defects while the other part thereof is returned with a mode conversion to longitudinal waves from transversal waves hitting defect once and reflected on the back thereof. These waves are measured. Since longitudinal waves are returned fast due to a greater sound velocity, it is determined based on the shape of parts to be inspected, incident angle used, the type of waves and the position thereof what kinds of waves return hitting defects and through what path they have passed. This enables quantitative measurement of the position and size of flaws and the like for even those places hard to move an ultrasonic probe having an axial curvature such as welded parts of bent tubes and reducer tubes at limited places to be performed with a high accuracy.

Title: Optical information recording/reproducing device
Inventor: NAKADA YASUO
IPC: G11B7/005
Filed: 1988-06-23
Abstract: PURPOSE:To keep the high quality of the reproduction signal even in the case the tracking servo accuracy is comparatively low by condensing the light beams so as to obtain an elliptical shape having its major axis in the direction orthogonal to the track direction for the shape of a light spot formed on a recording medium. CONSTITUTION:A light beam condensing means 3 consists of an optical element 6 having the astigmatism for example. Then an elliptical light spot 7 is formed on a recording medium 4 by changing the distance between the element 6 and the medium 4. When the information is recorded, an elliptical recording light spot 7a is formed on a recording area 4a of the medium 4. Thus the elliptical recording bits 8... are obtained. Thus a reproducing light spot 7b can overlap the bit 8 in the major axis side end area even in the case the spot 7b is offset in the direction orthogonal to the track direction. In such a way, the bit 8 can be surely detected and the high quality is kept for the reproduction signal.

Title: Wheel independent suspension device
Inventor: MURAKAMI TAKUYA
IPC: B60G3/18
Filed: 1991-06-03
Abstract: PURPOSE:To change a tow angle in a tow-in direction at the time of braking a suspension device which consists of one lateral link and one vertical link.

Abstract: PURPOSE:To correct sensitivity easily and securely by applying the conductive base of a photosensitive body directly and forcibly with a voltage which has the polarity and level corresponding to the sensitivity. CONSTITUTION:The photosensitive body 1 consists of the conductive base 10, photoconductive layer 11, and fixed flanges 12 and 13, and the fixed flanges 12 and 13 are conductors and contact the conductive base 10 directly, so a conductive brush 14 is brought into contact with, for example, the shaft part of the flange 12 to make a connection with a power supply 15, thereby applying the voltage to the conductive base 11 of the photosensitive body 1 directly and forcibly. When the applied voltage is -100V, the sensitivity is increased up to standard designed sensitivity, and when a +70V voltage is applied to the conductive base directly and forcibly, the sensitivity is decreased down to the standard designed sensitivity, so even a defective photosensitive body whose sensitivity is higher or lower than the standard designed sensitivity is usable as a normal photosensitive body.

Abstract: PROBLEM TO BE SOLVED: To facilitate the realization of always keeping constant a gap between a drum and a detecting element and maintaining high accuracy by loading a detecting element on the upper surface of a base which is brought into forced contact with a bearing to be positioned. SOLUTION: When a magnetic drum 1 mounted on a shaft 2 to be detected, which is a rotating shaft, is turned in a designated angle degree, a magnetic detecting element 4 which is a magnetic sensitive element and arranged near with a gap from a magnetic substance formed on the outer peripheral surface of the drum 1 detects the change of the magnetic poles of N-poles or S-poles polarized in a line by designated pitch on the magnetic substance, and outputs an electric signal corresponding to the direction of line of magnetic force and the number of magnetic fluxes. Thus, the turning angle of a designated angle of the shaft 2 which is a rotating shaft can be very easily detected, taking the drum 1 as a medium.  Furthermore, the rotation sensor can be easily fitted in the midway of the shaft to be detected which is a rotating shaft, and as the drum can be integrally installed on the shaft 2 to be detected, the rotation of the shaft 2 can be directly detected.

When a laser marking device is placed on a horizontal fixed face so as not to be tilted, the emission window 32 is situated in an erect position N, and the laser beam B is emitted to the outside via the emission window 32. In addition, when the laser marking device is placed so as to be tilted, the emission window 32 is tilted to a tilted position L or R. However, the laser beam B holds its vertical state due to the pendulum motion of a support arm.  In addition, the angle of inclination of the emission window 32 is set preferably at 6 deg. or lower.

Filed: 1983-08-30
Abstract: PURPOSE:To reduce the magnetic resistance of the junction part without the need of tightening members by a method wherein an annular magnetic core is composed of the assemblage of split bodies, which are then coupled into an integral body by the fit-coupling of grooves formed in the split body with projections thereof. CONSTITUTION:The choke coil consists of the annular magnetic core 3 and a coil 4 wound around this core. The core 3 is formed by the fit-coupling of the split bodies 5 and 6. The split body 5 is provided with the grooves 9 and 10 extending in the axial direction at both end surfaces 7 and 8, respectively. On the other hand, the split body 6 is provided with the projections 13 and 14 extending in the axial direction at both end surfaces 11 and 12. In such a construction, the split bodies 5 and 6 can be coupled only by fitting the grooves with the projections after winding each to the bodies 5 and 6, therefore the work of winding becomes easy, and the work of winding by means of machines can be also employed. Besides, since the junction area of the bodies 5 and 6 is made larger than that of the abutment of planes against each other, the magnetic resistance in the junction part can be kept low.
