Title: Method for moving head position for photographic enlarger
Inventor: YAMAMOTO SHOHEI
IPC: G03B27/32
Filed: 1988-01-08
Abstract: PURPOSE:To improve operating efficiency by positioning a head on a previously determined position without focusing. CONSTITUTION:When a negative film changing switch 56 is operated a head part 16 is moved to a negative film changing position (a low magnification position shown by an alternate long and two short dashes line) stored in a ROM in a microcomputer 54. At the time of moving the head part 16, a focus point adjustment part 18 is also moved at the same speed without changing the relative position between both of them. Since the head part 16 and the adjustment part 18 do not interfere with each other and adjusting the focus point is not performed, the head can be positioned on the negative film changing position faster than usual movement and positioning is comparatively roughly performed because exposure processing is not needed. Since the head part can be moved to a spot (low magnification position) within reach of an operator at a higher speed than usual at the time of changing a negative film 36 whatever position the head part exists in, the operating efficiency can be improved.

Title: Picture area identification system for picture processing unit
Inventor: SUZUKI YUZURU
IPC: G03G15/01
Filed: 1990-01-10
Abstract: PURPOSE:To identify a character, a dot and other medium tone picture depending on their run lengths and to identify a color original and a black/white original by processing block to each picture element so as to decide a block color. CONSTITUTION:A block processing section 3 applies block processing to each picture element into 4X4-8X8. A block decision section 4 decides a color with a maximum frequency in a block as to 7 colors (Y, M, C, K, B, G, R) except W and uses the result as a block color. The run length in the unit of picture elements is shorter and the run length of a dot area having been difficulty of segmentation from a character is extended. On the other hand, in the case of a character area, since the length between characters is longer than a pitch of dots, the block run length is decreased. Thus, the segmentation is made available from the standpoint of the block run length.

Title: Production of optical waveguide
Inventor: KANAMORI HIROO
IPC: G02B6/13
Filed: 1992-01-13
Abstract: PURPOSE:To decrease the scattering losses generated at the boundary between a core and a clad. CONSTITUTION:The core layer formed together with the lower clad layer on an Si substrate is formed to a core pattern by using RIE. A porous glass layer to constitute an interference layer of a thin film and a porous glass layer to constitute the upper clad layer are formed on the core pattern by a flame deposition method. The respective formed porous glass layers are thereafter heated to be made transparent, by which the optical waveguide of a flush type is formed. The refractive index having about 0.5 to 2mum film thickness has the same refractive index as the refractive index of the core pattern and, therefore, the ruggedness on the core pattern surface formed by the damage of the RIE is substantially flattened. Namely, the substantial core-clad boundary of the finished optical waveguide is a flat surface between the interference layer and the upper clad layer and, therefore, the scattering losses generated at the core- clad boundary are decreased.
