Title: Air conditioner provided with electronic dust collector
Inventor: HIRONAKA YASUMASA
IPC: F24F1/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To have a sufficient dust collection function and together with a deodorization function, to improve comfortness, and to contrive to increase compactness and low cost by positioning members for both dust collection function and deodorization function with appropriate space-efficiency in an air conditioner wherein an electronic dust collector is built inside a casing of an indoor unit. SOLUTION: Dust or particles floating in air passing through a draft route 31 are attracted to a dust collecting electrode 70 by electric discharge action of a dust collector 50 and subjected to electric precipitation. A catalyst layer 81 is formed on a surface of a thermal shield plate 80 for shielding from heat of a heater of the dust collector 50 and comprises a catalyst plate. An odor component contained in the air is adsorbed and deodorized by the catalyst layer 81. Relatively large surface area of the catalyst layer 81 allows adsorption action to the odor component to be conducted sufficiently. Heat generation of the heater of the dust collector 50 conducts self-cleaning of dust sicking to the dust collecting electrode 70, and simultaneously, radiation heat of the heater is transferred to the catalyst layer 81 to improve catalyst action.

IPC: G06F21/16
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To make a duplicated generation restriction control appropriate by managing another additional information by rewriting based on the additional information by means of an electronic watermark information.

Title: Manufacture of semiconductor wafer and semiconductor laser
Inventor: TAKAHASHI SHOGO
IPC: H01S5/00
Filed: 1991-11-06
Abstract: PURPOSE:To reproduce a non-sagging cleavage orientation flat edge face, and to facilitate the alignment of the late patterning by a method wherein a groove, which is parallel with the direction of an orientation flat, is made at least in the surface. CONSTITUTION:A stitch-like groove 31, which is in parallel with a cleavage orientation flat 2, is formed in a substrate 12 before crystal growth. Then, after a crystal grown layer 4 has been formed on the substrate 12, a non-sagging cleavage edge face 21, which is in parallel with the orientation flat on the end face other than the groove 31, is formed by cleaving along the groove 31. The succeeding patternings are conducted referring to the cleavage edge face 21, and a resonator in the direction vertical to the cleavage edge face 21 is formed. Also, since a groove is made in the surface of the substrate, it is unnecessary that the substrate is treated by turning it over, and the surface of the substrate is not damaged. As a result, the sagging of the initial cleavage orientation flat is removed, and the orientation of the new cleavage end face can be brought to the same orientation as the cleavage orientation flat.
