Title: Ultrasonic flaw inspection method for electroslag welding zone
Inventor: IWASAKI TETSUO
IPC: G01N29/04
Filed: 1985-11-11
Abstract: PURPOSE:To detect a defect in fusion securely and quantitatively by forming numbers of V-shaped grooves which are nearly constant in width, pitch, and depth in a groove face previously, and taking an ultrasonic flaw inspection test after welding. CONSTITUTION:Numbers of V-shaped grooves 9 which have about 1.6mm width W, about 1.6mm depth D, and about 3.0mm pitch P are formed in the groove face 3a of a weld base material 3. When an ultrasonic flaw inspection test is taken after the electroslag welding of this weld base material 3, an ultrasonic 2 transmitted by a probe 1 for an angle beam flaw inspection method is reflected in every direction and received partially by the probe 1 as a reflection echo 7 if there is a defect 6 in fusion in the weld boundary surface 4, thus detecting the defect. When the groove face 3a is fused normally as shown by a normal part 5, the ultrasonic wave 2 is not reflected.

Title: Recording device
Inventor: OGINO TAMIO
IPC: G03G15/043
Filed: 1983-12-23
Abstract: PURPOSE:To record easily only a required part of an original by controlling the light emission pattern of a light emitting means to a pattern corresponding to a prescribed part of the original in accordance with information from a selecting means. CONSTITUTION:When light is irradiated to the surface of a photosensitive drum 9 which is charged electrostatically uniformly by a charger 10, the conductivity in the part irradiated with the light is raised, and the electrostatic charge in this part escapes to a metallic cylinder. In a copying machine, a light emitting diode 25 which can irradiate light to the overall surface of the photosensitive drum 9 is provided between the charger 10, which charges the photosensitive drum 9, and the position where the photosensitive drum 9 is exposed to the reflected light of an original 2. Consequently, when the light emitting diode 25 irradiates the light to the overall surface of the photosensitive drum 9, an electrostatic latent image is not formed on the surface of the photosensitive drum 9 even if the photosensitive drum 9 is exposed to the reflected light of the original 2 due to an exposure lamp 5. Consequently, lighting and extinction of the light emitting diode 25 are controlled partially or with time to record the image of only one part of the original 2 onto a copy paper 13.

Abstract: PURPOSE: To provide such an exhaust gas recirculation valve as being compact in size and excellent in accuracy, which is able to check the wear or deformation of a valve element and a valve seat and to avoid any bounding motion. CONSTITUTION: When an armature 36 is displaced by the impression of voltage to a magnet coil 28, a second elastic member 62 is contracted against the resilience, and finally a washer 58c, this second elastic member 62 and the armature 36 all come to be integrally displaced in consequence. Accordingly, the armature 36 come into contact with the washer 58c, while a first elastic member 60 being energized in a valve closing direction is contracted against the resilience, whereby a valve element 54 separates from a valve seat 18. In consequence, an inlet port 12 and an outlet port 14 are interconnected with each other, so exhaust gas is induced.

The region A (positional information detected by an encoder) is stored and moreover, the gain of a concn. detecting sensor is adjusted based on the reflectance of the light of the point (a). After the adjustment, the process conditions (a grid voltage, a developing bias, etc.) are set to be in an initial state to form a toner patch in the region A and detect the density of the toner image of the patch. This toner density is stored as a reference value. When the timing of the correction of the density has just come, the toner patch is formed and its density is detected to correct the process conditions. Thus, the accuracy of the correction of image quality can be improved.
