Filed: 1988-07-26
Abstract: PURPOSE:To decrease curving of scanning lines by inclination of the reflecting surfaces of a polyhedral mirror by specifying the shapes of the respective reflecting surfaces of the polyhedral mirror and making plural laser luminous fluxes incident to these reflecting surfaces in the positions different with respect to the direction tangent to the rotating axis direction. CONSTITUTION:The laser luminous fluxes from laser oscillators 2a, 2b diagonally enter the reflecting surface 1a of the polyhedral mirror 5 in the positions different with respect to the direction tangent to said reflecting surface via anamorphic lens 4a, 4b. The incidence in the scanning direction is so executed that the laser luminous fluxes are condensed onto the surface 6 to be scanned by the combinations of the lenses 4a, 4b and the reflecting surface 1a of the polyhedral mirror 1. The laser luminous fluxes are once condensed to the reflecting surface 1a and thereafter, the luminous flux diverting from the reflecting surface 1a is condensed again onto the surface 6 by an anamorphic lens 5. The light is scanned in an arrow 6a direction on the surface 6 by rotating the polyhedral mirror 1. The polyhedral mirror 1 makes precession motion in this way and the reflected luminous fluxes are not affected at all even if the reflecting surface 1a inclines.

Title: Aluminum plated steel plate for easy to open can cap
Inventor: ARAI SHINICHI
IPC: C25D5/26
Filed: 1980-12-29
Abstract: PURPOSE: To obtain a titled Al plated steel plate of superior can openability and corrosion resistance by specifying the surface roughness of an underlying steel plate and the film thickness and surface roughness of Al plating.  
     CONSTITUTION: A steel plate having an Al-Fe alloy or Al plating layer of ≥ 5μm film thickness and of the max. surface roughness (Hmax) of the surface which is ≤1/2 the Hmax of an underlying steel plate of ≥5μm Hmax on said steel plate. If a score (notch) is inscribed on the Al plated steel plate, there is a tendency that the Al plating layer is held in the bottom of the score, resulting in increasing of the ratio of the thickness of Al. The presence of such Al layer of small shearing force in place of iron contributes unexpectedly largely to the reduction in can opening force as far as the plating film thickness is ≥5μm. Further, this effect promoted further in ≥5μm Hmax of the underlying steel plate with the same plating thickness. At this time, it is effective for prevention of exposure of the iron base in the rough raised parts owing to scoring and for reduction in can opening force on account of substantially increase thickness in the recesses of the underlying steel plate to make the plating surface as smooth as possible to the above-mentioned values.

Filed: 1981-11-24
Abstract: PURPOSE:To obtain a fluorescent screen with excellent intensity, contrast, and inherent color by introducing a purplish pigment made of a cobalt violet pigment or the like for a phosphor layer luminating in colors in a color picture tube. CONSTITUTION:To improve the contrast under the bright external light, a purplish pigment made of a cobalt violet pigment or an ultramarine blue violet pigment made of a cobalt violet pigment or an ultramarine blue violet pigment is introduced for phosphor layer luminating in red among phosphorus forming dot- like or belt-like phospor layers luminating in red, green, and blue by collision of an electron beam. Accordingly, the red tint of an inherent color generated by the reflected light in a red wavelength region is neutralized to approach a deep blue color by utilizing the high reflection factor characteristics of the purplish pigment in a blue wavelength region, thereby the unfamiliarity to a black level due to the external light can be eliminated and the intensity, contrast, and inherent color can be improved.

IPC: G03B15/05
Filed: 1989-07-18
Abstract: PURPOSE:To make the device compact and light in weight on the whole by moving flash light emission parts and varying the light distribution angle only by changing the rotating direction of one motor. CONSTITUTION:The reversible motor 3 is used and the flash light emission parts 22 - 27 are moved by the forward rotation of the motor 3 from their storage positions to use positions. Further, when a light distribution angle encoder 9 detects the angular position of a cam part 7b corresponding to the light distribution angle not being coincident with stored focal distance data, an arithmetic control part reverses the motor 3. Consequently, even when a lens is interchanged or a zoom lens is mounted and put in zooming operation, the light distribution angle can be varied to an angle corresponding to new focal distance. Consequently, the device is made compact, light in weight and small in size on the whole.
