Title: Color image forming method
Inventor: IKEDA ITSUO
IPC: G03F7/26
Filed: 1989-09-06
Abstract: PURPOSE:To inexpensively obviate the generation of harmful gases with a high sensitivity by pressuring a latent image surface to break the multinucleus capsules or paired capsules in non-exposed part, thereby selectively forming color developed dye images in the exposed parts of an image receiving layer. CONSTITUTION:All the multinucleus capsules are broken when the image receiving layer 61 contg. color developers are brought into contact with the multinucleus capsule layer surface and the entire part is pressurized. Since the mononucleus capsules 103r' in the multinucleus capsules 105r' in the exposed parts are cured at this time, only the cyan leuco dye soln. are released and come into contact with the color developers in the image receiving layer of these parts, thus developing a cyan color C. On the other hand, the uncured monomer, decoloring agent, cyan leuco dye soln., etc., are released from the multinucleus capsules 105r in the non-exposed parts, but the color development is hindered by the decoloring agent and the colorless W state is maintained. The negative-positive images which are of the cyan of the complementary color in the red light exposed parts of the image receiving layer and are noncolorless in the non-exposed parts are formed in this way. The images are thus inexpensively formed with the high sensitivity and the generation of harmful gases is obviated.

Title: Semiconductor laser device
Inventor: YAMASHITA KOJI
IPC: H01S5/00
Filed: 1984-11-01
Abstract: PURPOSE:To obviate the need of an external collimating lens, by utilizing a Fresnel zone plate as a window glass in front of a semiconductor laser beam. CONSTITUTION:A Fresnel zone plate 6 has annular patterns in which black portions are opaque to laser beams. The radius (rm) has a predetermined relation to a laser wavelength lambda and to a distance (f) from the end face of a chip to the plate 6 (focal length). The plate 6 may be produced by electronic beam exposure or the like. The resolving force and diffraction limit of the plate 6 are determined by a width of the annular belt having a maximum outer diameter, while the smaller width gives the better result. A numerical aperture is determined by the maximum diameter, and therefore a larger numerical aperture can be obtained than a conventional collimating lens. Radial laser beams 3 are diffracted when they pass through the plate 6 so that they constructively interface with each other in the direction of the optical axis, or in the parallel directions. According to this construction, a collimated beam having high output can be obtained. Further, the cost can be lowered.

Title: Electron beam dimension measuring apparatus
Inventor: TAKEUCHI SUSUMU
IPC: G01B15/00
Filed: 1992-08-31
Abstract: PURPOSE:To make dimensional measurement possible even if a fine pattern is formed obliquely or formed not oppositely by grouping similar signal waveforms in the vicinity of each edge and subjecting a pattern edge to linear proximation based on the coordinate positions of each waveform signal. CONSTITUTION:A measuring length calculator sequentially scans within a cursor 13 by means of an electron beam and detects an edge (x mark) with respect to a scanning line 17 and then temporarily stores signal waveform detected in the vicinity of an edge. The operation is repeated for all leads in the cursor 13 and when a final scanning line is confirmed, signal waveforms obtained in the vicinity of respective edges are compared each other and similar waveforms are collected to be grouped into groups G1-G4 for example. Linear proximation of pattern edge is then performed based on the position coordinates of grouped edges G1-G4 to determine lines L1-L4 and the distances between respective lines L1-L4 are calculated for each of the groups G1-G4 thus finishing measurement of length. This constitution allows dimensional measurement between lines even if fine pattern is formed obliquely or not oppositely each other on an object to be measured.
