Title: Production of hologram
Inventor: YUASA SATOSHI
IPC: G03F7/004
Filed: 1987-04-24
Abstract: PURPOSE:To reduce the variance in quality of the hologram by swelling and/or shrinking a recording carrier, followed by exposing the obtd. carrier to a solvent vapor. CONSTITUTION:The recording carrier contains mainly a polymer (such as polyvinyl carbazole) comprising a unit structure of an aromatic ring or a heterocyclic ring having a reaction position capable of substituting with a radical, and a halogen-contg. compd. (such as CI4). And, said carrier is formed an interference pattern by a radiation ray, preferably a latent image of a volume phase hologram, and then, swelling the obtd. carrier with a 1st. solvent (such as m-xylene), and shrinking it with a 2nd. solvent (such as n-hexane). Subsequently, the carrier 6 is placed in a vapor bath which put a nonwoven fabric absorbed the solvent such as n-hexane for a prescribed time, followed by drying. Thus, the adhered amount of a residual solvent is unified, and as the puddle of the solvent is reduced, an irregularity in drying of the titled hologram is prevented.

Title: Production of liquid crystal display element
Inventor: NAKAMURA KAZUYA
IPC: G02F1/1339
Filed: 1989-04-21
Abstract: PURPOSE:To obtain the liquid crystal display element which is regulated in the spacing between upper and lower substrates to a desired value by uniformly spraying spherical spacers formed by coating the circumferences of central nuclei consisting of a ferromagnetic material with a synthetic resin on substrate surfaces. CONSTITUTION:A spray nozzle 3 which ejects the air contg. the spacers 1 toward the glass substrate 5 is provided above the substrate 5 and a cover 4 bored with a slit 7 for dispersion is installed between the nozzle 3 and the substrate 5. Further, DC electromagnet coils 6 for attracting the spacers are disposed alongside both ends of spray patterns. Since the spacers 1 having the central nuclei made of the ferromagnetic material are dragged laterally, i.e. toward both end sides of the substrate by the electromagnet coils 6, the spacers 1 are distributed at nearly a uniform density over the entire part in the transverse direction of the substrate 5. The spacers 1 which are not too hard and are not too weak are nearly uniformly dispersed and disposed on the substrate in such a manner and, therefore, the uniform formation of the spacing size between the upper and lower substrates to the desired value is possible.

Title: Transistor converter circuit
Inventor: KASHIWARA TOSHIJI
IPC: H05B41/24
Filed: 1978-08-17
Abstract: PURPOSE:To control the oscillation of an oscillation transformer depending on the condition of a load, by simultaneously raising the low voltages of various low-voltage sources to high levels through the single oscillation transformer and providing a constant voltage circuir. CONSTITUTION:The voltage of a low-voltage source 1 for a stroboscope is changed into a high voltage by a transistor 3 and the oscillation transformer 4 when a switch 2 is closed. The high voltage is appears on a secondary winding 42 of the transformer to charge a main capacitor 13 to energize a light emitter 14 including a flash discharge tube or the like. The voltage of a ppwer source 15 for a motor driver or the like is changed into a high voltage by a transistor 8 and the oscillation transformer 4 when a switch 16 is closed. The latter high voltage appears on the secondary winding 42. Since both the high voltages are superposed on each other by the single oscillation transformer 4, the stroboscope can be frequently energized. The charged voltage of the capacitor 13 is kept constant by the constant voltage circuit 17.

Title: Printer
Inventor: YAMAGUCHI HIDEKI
IPC: B41J13/00
Filed: 1988-04-23
Abstract: PURPOSE:To prevent a discharged and fed printed sheet part from again entering a printer from a paper feed port, by providing a movable shutter member for selectively changing over a cut sheet manual insert paper feed port to an opened state and a closed state to hold either one of both states. CONSTITUTION:At the time of a paper feed mode by a cut sheet feeder, a shutter member 30 is changed over to a closed state and held to said state to close a manual insert paper feed port 12. By this mechanism, even when a printed sheet part discharged and fed from a paper discharge port toward a paper discharge stacker goes toward the paper feed port 12 by an unstable discharge posture, the shutter member prevents such an accident that said sheet part again enters a printer from the paper feed port 12. As a result, a stable paper feed/discharge state can be secured.
