Title: Manufacture of extra-low carbon high tensile steel with very high ductility
Inventor: YAMAMOTO SADAHIRO
IPC: C22C38/38
Filed: 1978-04-18
Abstract: PURPOSE: To manufactue an extra-low carbon high tensile steel with very high ductility by utilizing the crystal-fining and crystallization strengthening effect of Nb, V, etc., by rolling controllably an extra-low carbon steel containing any one or both of specific amounts of Nb and V.  
     CONSTITUTION: The extra-low carbon steel used contains <0.015% C, 0.05 to 0.60% Si, 0.60 to 2.20% Mn, 0.005 to 0.10% soluble Al, and 0.03 to 0.20% V or/and 0.03 to 0.15% Nb, together with, as needed, one or two or more of <0.50% Cr, <0.50% Cu, <0.50% Mo, and <2.0% Ni. After controlled rolling, the steel, the carbon equivalent of which is less than 0.36, is subjected to an accelerated cooling to 500 to 650°C at a cooling rate of 3 to 15°C/sec and afterwards cooled by air. Thus, a strength of 60 kg/mm 2  can be obtained, combined with the addition of Cr, Cu, Mo, Ni, etc.. The steel is thus suitable as line piping material in the cold areas because of its small carbon equivalent and excellent toughness.

Title: Antiskid controlling device
Inventor: FUKUDA MITSUNOBU
IPC: B60T8/72
Filed: 1990-02-26
Abstract: PURPOSE:To perform a good antiskid control by composing a wheel speed selecting means to decide a wheel speed selected based on a result of detection by a brake condition detecting means and a detected value of acceleration/ deceleration by an acceleration/deceleration detecting means at the time of non-antiskid control condition. CONSTITUTION:When a control condition detecting means detects a non-antiskid control condition, if a detected acceleration is larger than 0g under a brake condition by stepping of a brake pedal, for example, or if it is larger than -0.2g under a non-brake condition, then it is determined that there will be not possibility of an antiskid control, and a select-low wheel speed for each detected wheel speed is selected. A pseudo speed following an actual car body speed can thus be computed correctly. For the other cases, it is determined that there will be a possibility of the antiskid control, and a higher select-high wheel speed among detected wheel speeds for the four wheels is selected, so the pseudo speed just before starting the antiskid control is set to follow the actual car body speed.

Title: Optical scanning device
Inventor: NAGASHIMA KANJI
IPC: G03G15/04
Filed: 1989-02-28
Abstract: PURPOSE:To prevent an image formation position from shifting owing to surface inclination by using plural beams which are incident on a rotary polygon mirror at the same beam incidence position and imaged on a scanned body at different image formation position in a main scanning direction, and emitting one of the beams selec tively according to the surface tilt angle of each surface. CONSTITUTION:A beam irradiation scanning line formed on the scanned body by main scanning is at a certain angle to the main scanning direction because of the movement of the scanned body in a subscanning direction. Here, one of the beams is emitted selectively according to the surface tilt angle of each surface of the rotary polygon mirror 270 and while the angle of incidence on the rotary polygon mirror 270 is varied, the angle of incidence is varied by a movable mirror 262 to set an image formation position within the range of the angle of incidence, so that an image formation line can be adjusted within the width in the subscanning direction. Namely, the angle of incidence for compensating the dislocation in the image formation position due to the surface inclination of the rotary polygon mirror 270 is set for each surface of the rotary polygon mirror 270 corresponding to the dislocation in the image forma tion position. Consequently, the dislocation in the image formation position is eliminat ed to obtain an image having no density irregularity.

Title: Breeding by maintaining packed gas in liquid
Inventor: NOJIMA YOKO
IPC: A01G31/00
Filed: 1988-02-27
Abstract: PURPOSE:To simply prevent occurrence of oxygen deficiency, by maintaining bags of thin film having enclosed a gas such as oxygen in water and breeding underwater organisms in liquid rich in oxygen on the surface of the film of the bags or in the vicinity thereof. CONSTITUTION:Bags of thin film having enclosed a gas such as oxygen are maintained in water and underwater organisms (e.g., eel or quahaug) are bred in liquid rich in oxygen on the surface of the film of the bags or in the vicinity thereof. A material such as vinyl resin, cellophane, rubber or 'Saran Lap(R)' is used as the material of the film. Consequently, since the gas such as oxygen enclosed in the bags permeates through the thin film and comes out from the bag by diffusion phenomena, occurrence of oxygen deficiency can be prevented. When rubber is used as the material of the film, the film is not only simply handled but also can be expanded and shrunk and a cell group attached to the surface of the film and cultivated can be safely and surely floated in liquid.

Title: Holographic stereoscopic hard copy and its formation and device
Inventor: HONDA TOSHIO
IPC: G03H1/26
Filed: 1990-02-28
Abstract: PURPOSE:To use element holograms as a hard copy of a solid body by forming plural dot-shaped element holograms on the surface of a base material. CONSTITUTION:An image pattern is displayed on a liquid crystal panel 10 and its transmitted light is converged on a hologram surface through a lens 12. Reference light is made incident on this light convergence part 15 from the opposite direction and an interference fringe pattern formed with the reference light is recorded on the hologram surface 14 as dot-shaped element holograms. A hologram film is moved slightly in the longitudinal and lateral directions and exposed in order to obtain the dot-shaped element holograms on the entire surface of the hologram. In the recording of a holographic stereogram(HS), a light beam is converged in the same direction with original image pattern calculation and a Lippmann hologram is recorded. Consequently, the stereoscopic hard copy having a parallax vertically and horizontally can be obtained.
