Title: Optical system with incorporated optical system and television for increasing presence of various images
Inventor: TANAKA JUNICHI
IPC: G02B27/22
Filed: 1991-03-11
Abstract: PURPOSE:To increase the presence of various images obtained by a single-lens camera without increasing the size of a screen by forming a virtual image of an object on a lefter side for the left eye and a righter side for the right eye from, positions where the object is viewed with the naked eyes, ideally, right in front of both the eyes. CONSTITUTION:Operation for splitting, reflecting, or refracting a light beam from the object that a user sees or performing them in combination is added. For example, reflecting mirrors 1a which have their reflecting surfaces slanted at 45 deg. to the intermediate direction between both the right and left eyes are provided right in front of the eyes, and a couple of reflecting mirrors 1b which have their reflecting surfaces slanted at 45 deg.-X/2 from the front to both outsides are provided between both the eyes. An angle 2X corresponds to the parallax angle of the center point P of an image at a distance which is a half as long as the distance from the center between both the eyes to both the eyes. The angle difference of the reflecting mirror 1b or 1a is finely adjusted corresponding to the distance of the center point P to form the virtual images of the center point P right in front of both the right and left eyes at all times, so that the parallax angle becomes 0.

Title: Vibration fatigue controle method for material
Inventor: ODA MASAHIRO
IPC: G01N3/34
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a vibration fatigue control method for a material allowing determination of whether a vibration fatigue in the material is in a progressing state or not by a simple method. SOLUTION: While a normal forced vibration applied to a socket welded part 40 is stopped, an elastic wave is applied by hitting a part of the socket welded part 40 with a hammer to damp the forced vibration, a relative displacement between first and second measuring parts T1, T2 is measured by accelerometers 31, 32. An intensity of an n-th harmonic wave in respect to a base vibration wave at the socket welded part 40 is obtained by analyzing the damping vibration in terms of time-frequency. A displacement width in a transition area where the n-th harmonic wave increases/decreases is obtained as a lower fatigue limit amplitude.  Then, while the normal forced vibration is recovered, a management on whether a vibration fatigue is progressing or not is conducted based on whether a relative displacement between the first and the second measuring parts T1, T2 exceeds the lower fatigue limit amplitude.

Abstract: PURPOSE: To make possible automatic stopping in all operation states of recording, reproducting and rewinding with an inexpensive constitution by a rotating member which is rotated by a motor after releasing the diving force of reel shaft, an eccentric cam provided to a rotating pulley and a releasing member.  
     CONSTITUTION: As power source is turned ON, a motor revolves, causing a drive pulley 3 to be revolved by a belt 4. The revolutions thereof cause a drive gear 5 to be revolved by way of a felt 6. The tape drive operation displaces an operating lever 13 in the operation position and a first gear 14 intermeshes with the drive gear 5 and a second gear 15 with a driven gear 11, then a reel shaft 11 revolves and the tape is taken up. At the final end thereof, the reel shaft 10 stops. And the transmission member 12 formed with the second gear 15 also stops revolving and the drive gear 5 stops as well. As the drive gear 5 stops, the rotating member 7 also stops, then there is no more rotating force of the releasing member 21 in its counterclockwise direction, and the releasing member 21 displaces clockwise as an eccentric cam 19 makes contact with a contact piece 23. As a result, a releasing piece 26 contacts a releasing lever 25, which in turn displaces in the arrow A direction, thus unlocking the push-button and stopping the recorder

Abstract: PURPOSE:To prevent sudden consumption of a negative electrode by providing working gas blowout nozzles on the same axis as the negative electrode and arranging a magnet to the lower part of the negative electrode and bringing the Lorentz's force acting on the negative electrode in line with the turning direction of working gas. CONSTITUTION:The gas blowout nozzles of a working gas supply path 2 is provided on the same axis as the negative electrode 1 and further, the magnet 7 to generate a line of magnetic force is set up in the vicinity of the lower part of the negative electrode 1. At this time, in order to generate the turning flow of working gas to surround a plasma arc, the working gas blowout nozzles 8 are pierced and formed in the magnet 7. Since the working gas blowout nozzles 8 are provided in the magnet 7 itself and the magnet 7 is arranged in close vicinity to the negative electrode surface 1a, the acting force of the magnet 7 increases. By this method, the Lorentz's force on the negative electrode surface is brought in line with the turning direction of the working gas and the turning motion of a discharging point is stabilized. Accordingly, the sudden consumption of the negative electrode is prevented.
