Title: Three-dimensional optical memory glass element and its recording method
Inventor: MISAWA HIROAKI
IPC: G11B7/0045
Filed: 1995-02-13
Abstract: PURPOSE: To enable recording at a good contrast and high density with a spot smaller than the wavelength of a laser beam by condensing pulse lasers and irradiating a glass matrix with the condensed laser while three-dimensionally operating this glass matrix, thereby inducing a photo-induced refractive index change at the microspot. CONSTITUTION: The picosecond pulse lasers of a wavelength 532nm which is the double waves of a Q-switch Nd:YAG laser 1 are used for the laser for recording. These picosecond pulse lasers are condensed to the spot of about 600nm by using an oil impregnated objective lens 3. The glass matrix 4 sized 15×15×0.7mm is irradiated with this spot beam in the state of focusing the spot at the inside of the matrix. The microspot accompanying the refractive index change is formed near the focus. The diameter is 600nm when the pulse laser beam intensity is 420J/cm<2> if the spot is recorded by a CCD camera and a video 6 and its size is measured. Further, the spot of the laser wavelength or below is formable as well if the laser beam intensity is further weakened.

Title: Sheet carrying device
Inventor: SUGANO TADAAKI
IPC: B65H29/58
Filed: 1979-03-01
Abstract: PURPOSE: To simplify the structure of direction converting section in a device for carrying the sheet in different direction from carry-in direction, by pressure contacting a sheet carrying ball against circumferential rotary face of roller in sheet carrying direction converting section.  
     CONSTITUTION: When a detecting means detects the provision of copy sheet into carry-out device, excitation of electromagnet 60 is interrupted thereby steel ball 67b contacts against the roller 27b with its weight. The copy paper is carried while pressure contacted between the steel ball and roller. Since a plurality of rollers are arranged in the carry-out device while perpendicularly crossing the rotary axis, the carried-in copy paper can be carried out perpendicularly against carry-in direction when controlling the pressure contact of steel ball against each roller in accordance with the carrying-in of copy paper.

Title: Magnetic bubble memory device
Inventor: AKIBA YUTAKA
IPC: G11C11/14
Filed: 1989-02-03
Abstract: PURPOSE:To improve the uniformity of a holding magnetic field by shifting in parallel and placing the center axes of the upper and the lower magnet plates in a bias magnetic field generation use magnetic circuit. CONSTITUTION:When a bubble chip 2 is inclined by an angle theta against a magnet plate 7, a holding magnetic field HDC is given by an expression I. An edge effect of the magnet plate is given by a second term of the expression I. At the time of approaching an end part of the magnet plate 7, an HX component increases, and also, HX is generated in the direction for negating a first term of the expression I, therefore, uniformity of the magnetic field HDC is deteriorated. Therefore, by shifting in parallel and placing the upper magnet plate and the lower magnet plate 7-1, 7-2 in the positive and the negative directions, respectively against the X axis direction, HX is not generated in the end part against the chip 2, and even if it is generated, it exists in the direction for strengthening a first term of the expression I, and the uniformity of the magnetic field HDC can be improved.
