Title: Probe shoe for oblique ultrasonic flaw detection
Inventor: FUKUMOTO MITSUNOBU
IPC: G01N29/28
Filed: 1980-10-27
Abstract: PURPOSE:To detect and evaluate even a defective slanting to an ultrasonic wave beam, transmitted from a probe, by setting a reflector at the skip point of the beam and by measuring the extent of attenuation of an echo from an ultrasonic-wave reflector. CONSTITUTION:An ultrasonic wave transmitted from a probe 1 is incident to a steel plate 2 as shown by a route 3 and travels while reflected by top and reverse boundary surfaces, but skip points change according to the plate thickness of the steel plate 2. According to a change in skip point, an ultrasonic-wave reflector 17 is fixed with a screw 19 where a maximum reflection echo is obtained. In this state when the oblique flaw detection of the steel plate 2 is performed, the echo from the reflector 17 apears at a constant position at a distance from the beam route 3 all the time at a perfect part free of defection, and for a defective having a reflective surface at right angles to the beam, a defective echo appears in the beam route 3; and the echo from the reflector 17 attenuates in proportion to the size of the defective. When there is a detective slanting to the beam, the beam is cut off and the echo from the reflector 17 also disapears.

Title: Recording and/or reproducing device
Inventor: SHINADA SATORU
IPC: G11B19/10
Filed: 1993-05-31
Abstract: PURPOSE:To reduce the factors of failures and to improve the reliability of equipments by detecting the loading of a disk on a recording/reproducing position based on a signal obtained from a laser reflected light to the disk moving at the time of a loading operation. CONSTITUTION:In the case that a distance between a disk surface 1 and an objective lens 3a is within a focus drawing allowable range at the time of focus searching, an FOK signal showing this is inputted from an RF amplifier to a CPU 11. Since the lens 3a is on a highest position within an up-and-down movement allowable range L at this time, the FOK signal is obtained even during the period when a disk cartridge is lowered for loading. Thus, the loading of the disk on the recording/reproducing position is discriminated when the FOK signal is inputted at the CPU at the time of loading and no holding of the disk by a cartridge holder is discriminated when no FOK signal is inputted.

Filed: 1991-06-21
Abstract: PURPOSE:To obtain a simple and small-size device by a method wherein a wiper device for cleaning a jet nozzle surface consists of a flexible wiper blade and a rigid body provided adjacently to the wiper blade. CONSTITUTION:A carriage 2 with an ink jet head 1 formed by joining a base plate 1a to a second base plate 1b travels in the direction indicated by arrow A. A rigid body 4 is adjacently provided on the side surface of a wiper blade 3 in the direction A to arrest the bending of the wiper blade 3. As a result, since only the tip end of the wiper blade 3 projected from the rigid body 4 is bent with a small bending radius, by a large restitutive force, the wiper blade 3 is strongly pressed down to the front surface of the ink jet head 1 to wipe ink and dust. When the carriage 2 moves in a opposite direction, the wiper blade 3 is largely bent with a large bending radius accompanied by a small restitutive force because the wiper blade 3 having no rigid body 4 on the opposite side face thereof cannot be prevented from bending by the rigid body 4. Therefore, the second substrate 1b is never released from the base plate 1a because of a small force acting to release the former from the latter.
