Title: Optical scanning method
Inventor: ABE MICHIHARU
IPC: H04N1/04
Filed: 1979-07-19
Abstract: PURPOSE: To scan a scanned object linearly in a uniform speed with a simple mechanism, by arranging the scanned object on the cylinder face coaxial to the hologram rotary material and by performing scanning while displacing the scanned object and the rotary material in the rotating shaft direction of the rotary material relatively, in the optical scanning system using hologram.  
     CONSTITUTION: Plural similar holograms Hi are recorded on rotary disc 1 fixed onto rotating shaft O of motor 2. When reproducing light beam 3 is made incident in a prescribed position through an aperture smaller than the recording area of one hologram Hi, reproducing light beam diffracted ray 4 is generated. Reproducing light beam 4 is focused onto scanned object 5 arranged on cylinder face 20 coaxial to rotary disc 1. Motor 2 is rotated to displace scanned object 5 in the rotating shaft 7 direction relatively to rotary material 1. As a result, the scanned object can be scanned linearly in a uniform speed practically with simple mechanism.

Abstract: PURPOSE:To improve the extent of heat transfer performance by forming a heat exchanger plate where snow lies, an evaporating part storing a working fluid, a header being interconnected to this evaporating part, a condensing part in thermal contact with the heat exchanger plate, and an electric heater heating the working fluid, respectively. CONSTITUTION:An electric heater 14 is energized with current and thereby a working fluid in an evaporating part 11 is directly heated and vaporized, absorbing a heating value of the electric heater 14 as a steam latent heat, and this fluid flows into the one side of a condensing part 13 from a steam space of a header 12, then it is moved to the other side. Next, a side of a heat exchanger plate 10 set up in thermal contact with the condensing part 13 is lower in temperature than heat of the electric heater 14, so that steam is condensed and liquefied, discharging the condensed latent heat to the heat exchanger plate 10 from each condensing part 13, and the plate 10 is heated whereby snow on the plate is thus melted. Then, the liquefied working fluid goes along a wall surface of the condensing part 13 and flows back to the inside of the evaporating part 11 from the header 12. With this constitution, the extent of heat transfer performance is improvable in a simple structure.

Abstract: PURPOSE:To obtain a high-recording-density medium which is manufactured easily floats by a small extent, by preventing the adsorption phenomenon between the medium and a head by forming nonmagnetic cylindrical fine projections on a magnetic medium layer. CONSTITUTION:On a magnetic layer 2 on a base disk 1, fine projections 3 are provided for preventing adsorption. There is a base layer between the base disk 1 and magnetic layer 2 occasionally and a protective film is formed on the magnetic layer upon occasion.

Abstract: PURPOSE:To prevent the flaw or damage of an article discharged from a high position to a low position. CONSTITUTION:An article receiving enclosure 35 receives a metal sheet carried through a gap between an advancing shutter rod 471 at the closed bottom section 35a of the enclosure 35 and a connecting shaft 433 for connecting gears 413 and 423 to each other. The enclosure 35 is lowered to the predetermined discharge height by the operation of a motor 61 of a lift drive device 60, after receipt of the metal sheet.
