Abstract: PURPOSE:To eliminate the influence of the change of an environmental temperature and to detect an information signal with a high frequency, by bi-secting a beam of light at a part where a sufficient large diameter of light beam is provided by a mirror, and furthermore converging the beams of light by a lens. CONSTITUTION:Reflected light from a disk 4, after transmitting a half mirror 2, is divided at the part where the diameter of the beam of light is large by the mirror 10 in advance, and is converged as two optical spots R by a convex lens 8. Thereby, the lowering of the detecting capacity of a tracking error signal can be evaded even when the micro displacement of an optical head is generated by the change of the environmental temperature, etc., and the center part of incident beam of light to the mirror 10 and the parting line of the mirror 10 are displaced relatively. Also, since a miniaturized and superior bi-sected optical detector 9 is prepared, a joining capacity can be reduced, and the information signal with the high frequency can be detected by an adder amplifier 7.

Namely, the gas passes through the detour hole 10 provided in a lens holder 4 for light convergence, reaches the holder 4 of the input coupling part while cooling the internal wall of the waveguide, and flows out of the gas outlet 13. Further, the protection tube 11 is provided coaxially at the periphery of the hollow waveguide 1. Then part of the assist gas which flows in the detour hole 10 flows in the gap between the protection tube and hollow waveguide 1 which constitute the 2nd flow passage and reaches the input coupling part while cooling the external surface of the hollow waveguide 1. Thus, the internal wall and external wall of the waveguide are cooled at the same time to increase transmitted electric power.

Title: Photographic material for printing
Inventor: SUZUKI TAKEYUKI
IPC: G03C1/825
Filed: 1980-10-06
Abstract: PURPOSE:To obtain a photographic material for printing improved in resolution, by forming a hydrophilic colloid layer containing a white pigment and a dye on a polyolefin-coated paper support. CONSTITUTION:A hydrophilic colloid layer containing a white pigment, and a dye absorbing the light in the photosensitive wavelength region of a silver halide emulsion layer, and being decolored in a developing process is coated on a coated paper support by the medium of a subbing layer or without this, and silver halide emulsion layers are formed by coating them on this colloid layer. Since an amount of the white pigment in the polyolefin layer of the polyolefin-coated paper is kept small to  retain the physical property of the polyolefin, the light shielding effect is not enough,  and the light is scattered in the polyolefin layer, resulting in deteriorating its resolution as compared with baryta paper. Simultaneous addition of the white pigment  and the dye permits exposure caused by light scattering to be prevented synergistically, and resolution to be enhanced.
