IPC: G01N21/41
Filed: 1978-09-25
Abstract: PURPOSE: To measure the aberration simply and promptly from the distorsion aberration and the curvature of field of the image of a standard pattern, which is focused through a lens medium to be tested.  
     CONSTITUTION: A white light source 11 is adjusted to have a monochroic light by a monochrometer 12, and a grating fringe 13 is focused through a lens medium 14 to be tested so that the focused image is observed by means of a microscope 15 which has its focal plane (for observation) in the direction of the optical axis. A TV camera 16 is connected with the microscope so that the image pattern is observed by means of a monitor TV set 17. A brightness distribution along the scanning line in the vertical direction appears as the pattern on the monitor TV so that the most clear image may be attained. Thus, the aberration is determined from the distorsion aberration and the curvature of field.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To make an optical image forming means highly efficient in an optical printer head that makes light from a light source form an image on a recording medium by an image forming means. SOLUTION: Between a fluorescent arc tube 15 and an SLA 10, and between the SLA 10 and a recording medium 20, four light reflecting members 25, 26, 27 and 28 are provided mutually parallelly in four positions symmetrical relative to the central face 12 of the SLA or the optical axis face 13 of an optical path. In relation to an upper row and lower row of luminous dots 1 and 2, the lower side of the optical axis has a light quantity transmission rate opposite to the upper side of the optical axis. When ghosts 1c and 2c are superposed on real images 1a and 1b from above and below, an equal light quantity improvement is realized. In the SLA 10, the loss in the quantity of light due to a lens itself is very small, so the light quantity transmission rate is determined by the quantity of incident light on the lens.  If the reflectance of the reflective members is 95%, and 90% in two reflections in relation to an improvement of 50%+30%=80% in the quantity of light for the real images, about 70% improvement in the total quantity of light can be expected. It is equivalent to an efficiency improvement equal to the arrangement in four rows of SLA 10 in two row specification.

IPC: B29C45/14
Filed: 1991-05-24
Abstract: PURPOSE:To prevent the imperfect processing of a printed wiring board by a die from occurring at a boundary part between the rigid structure part and the flexible structure part of the printed wiring board possessed of the rigid structure part and the flexible structure part formed into one piece with injection molding resin and to protect a circuit pattern against disconnection caused by the excessive pressure of molten resin at injection molding. CONSTITUTION:A film 1 is inserted between a die 2a provided with a buffer material 5 installed at a prescribed position and a die 2b cutting-processed as deep as the prescribed thickness of a film 1 and a resin board 3, and then the dies 2a and 2b are clamped. The cutoff or the scuffing of the film 1 caused by imperfect processing at the end 7 of the die 2b can be prevented by the buffer material 5. Thereafter, the pressure of the molten resin is absorbed and relaxed by the buffer material 5 when molten resin is injection-molded, whereby a printed board where the film 1 and a resin board 3 are formed into one piece and a circuit pattern is protected against disconnection can be obtained.

Title: Magneto-optical recording and reproducing device
Inventor: YAMADA AKIHIRO
IPC: G11B11/105
Filed: 1990-05-11
Abstract: PURPOSE:To attain substantial overwrite through the use of one set of optical head by driving a disk rotary device at a double speed so as to trace a same recording track twice each, erasing recording at the 1st tracing and writing information at the 2nd tracing. CONSTITUTION:An input signal fed to a magneto-optical disk 1 is subject to 1/2 time axis compression by a time axis compression circuit 11, the disk 1 is driven at a double speed in comparison with the case without time axis compression to trace the recording track twice each at double speed thereby making erasure at the 1st trace and writing at the 2nd tracing. Since the processing above is repeated for each recording track, it is equivalent to overwrite at a usual recording speed from the standpoint of the device operation. Moreover, the relative speed between the disk 1 and an optical head 5 and the recording density are unchanged from those at the normal operation because the disk 1 is driven at a double speed and writing is implemented at a double frequency. Thus, the optical recording reproducing device is realized, in which one optical head is used for overwriting.
