Title: Optical semiconductor element
Inventor: SUZAKI SHINZO
IPC: H01L27/15
Filed: 1987-12-17
Abstract: PURPOSE:To cover a wide wavelength range by one element by forming a plurality of active waveguides having compositions having different wavelengths and low loss waveguides bundled to one near a light outgoing end into the same substrate. CONSTITUTION:The sections of the inner part sides of active layers 4, 5, 6 are removed through selective etching, and a low loss waveguide 3 and a clad layer 8 are laminated successively. Reverse mesa etching is conducted so that each active layer 4, 5, 6 is isolated and the low loss waveguide 3 is collected to one on the inner part side, and electrode block layers 15, 16 are buried and grown so as to cover the periphery of the reverse mesa etching shape. Lastly, electrodes 10, 11, 12 are formed to sections corresponding to respective active layer 4, 5, 6 on the top face of the clad layer 8. Since each emission wavelength of the active layers 4, 5, 6 differs, a wavelength range as a whole is broadened extremely. Accordingly, the wide wavelength range can be covered with one element.

Title: Light source construction for optical system
Inventor: HASHIMOTO YUKIO
IPC: G03B27/54
Filed: 1990-11-21
Abstract: PURPOSE:To effectively shield the heat of a lamp by slidably providing a shutter on a closing position to shield an irradiation window and an opening position on the return movement direction side against the closing position above a light source. CONSTITUTION:A shutter 4 is slidably provided on a closing position to shield an irradiation window 6 and an opening position on the return movement direction side against the closing position above a light source 1. Consequently, when scanning drive is commenced from a home position to a return position, the shutter 4 is relatively moved reversely against the scanning direction by inertia force to open the irradiation window 6. At stopping on the return position and at commencement of return movement from the return position to the home position, the shutter 4 is moved by inertia force against the upper part of the light source 1 to close the irradiation window 6. Hereby, during returning from the return position to the home position, the heat of a lamp can be shielded.

IPC: B65D65/40
Filed: 1990-11-27
Abstract: PURPOSE:To prevent oxygen barrier properties from lowering with time by a structure wherein at least one layer of the packaging body contains substance having oxygen adsorbing function under the condition being microencapsulated and sealed with water soluble polymer. CONSTITUTION:The packaging body 10 concerned is a bottle having multilayer structure or consisting of outer layer 1/bonding layer 2/oxygen barrier layer 3/bonding layer 4/inner layer 2.

IPC: G03F1/76
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a coordinate distortion correction method capable of obtaining a reticle without causing any distortion. SOLUTION: A positioned grid pattern is plotted on the reticle 11, and by measuring the coordinate of the plotted grid pattern by a size measuring device, a difference between with an ideal grid pattern is found, and coordinate distortion in an XY stage 10 is found.
