Title: Color printer
Inventor: KIMOTO ISAO
IPC: B41J2/215
Filed: 1989-04-13
Abstract: PURPOSE:To obtain a color image of high resolution easily without the blocking of a nozzle by allowing a jet stream to pass through an atomized ink atmosphere, transforming ink particles into microparticles under a pinch effect and causing the microparticles to run into the paper surface with the help of a jet stream to form a printed image consisting of minute dots. CONSTITUTION:A nozzle 1 which forms a jet stream 3 consists of an outer pipe 1a which is gradually tapered off at the tip 1a and a small-dia. inner pipe 1b, and both pipes are coaxial. A compressed air which is supplied continuously from the side of a base is ejected to the surface of recording paper 2 at low speed from the outer pipe 1a. In addition, a compressed air which is supplied continuously from the side of a base is ejected to the surface of the recording paper 2 at high speed from the inner pipe 1b. A jet stream 3 ejected from the nozzle 1 passes through an atomized ink atmosphere 4 before reaching the surface of the paper 2. In this case, microparticles 4a are formed at the same time as the atomized ink is engulfed by the jet stream 3 under a pinch effect. Furthermore, these microparticles 6a are condensed into a small beam 4b and this beam 4b reaches the surface of the paper to form minute dots.

Abstract: PURPOSE: To prevent corners of an almost square chip from being damaged, at the time when a case is being pressed into a heat-radiating plate, by changing dimensions of a relief groove, provided on a base plate in the case, in accordance with dimensions of the chip.  
     CONSTITUTION: When an aluminum heat-radiating plate 7 with an inner diameter of R 2  is pressed into a case 2 of a semiconductor device with an outer diameter of R 1 , the heat-radiating plate 7 is deformed very little and the case undergoes a compression deformation of ΔR almost equal to (R 1 -R 2 ). For this reason, a flexure of ΔZ is caused to a bottom plate 21, a stress F is caused to a silicon chip 1 and, particularly, the stress becomes its maximum when caused to 4 corners of the chip. As a result of numerical analysis of this phenomenon, it proved that by providing a relief groove on the bottom plate in a convex-type case and by maintaining a relationship of 0.1×a≤T'/T among the groove depth T', the bottom's flat section thickness T and the silicon chip's one side a, it is possible to control the shear stress at the 4 corners under the silicon-damaging strength.

Abstract: PURPOSE:To enable the highly precise detection of position, by a method wherein marks on two substrates are illuminated by lights of two wave lengths which are set so that a difference in intensity to lights from peripheral parts of patterns be equal substantially. CONSTITUTION:In an optical system in the left half (in the one in the right half as well) of an observation apparatus, light fluxes emitted from white-light sources 1L and 3L illuminate patterns 13L and 14L formed of transparent electrode thin films on glass substrates 11 and 12, through BPFs 2L and 4L, half mirrors 7L and 8L, a stop 9L, an imaging lens 10L, etc. The lights reflected by the patterns 13L and 14L enter an image pickup tube or the like through the imaging lens 10L, so that images of the patterns 13L and 14L be formed. The BPFs 2L and 4L, which are made to be different in a transmission wavelength, are selected so that the sum of the reflected light intensities of a monochromatic light in relation to the respective reflections of the patterns 13L and 14L is equal. Therefore, a difference in intensity to lights from peripheral parts of the patterns is equal substantially, and thus the two patterns can be observed simultaneously in stable and substantially equal contrasts.

Title: Image recorder
Inventor: NAKAMURA HIROAKI
IPC: G03B27/46
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To save the manpower of printing processing by performing the printing processing without requiring manual intervention as much as possible even in the case of a request for printing plural prints. SOLUTION: Based on a result obtained by performing the photometry of an image G recorded on negative film 10, areas f1-f4 equivalent to the faces of persons P1-P4 in the image G are extracted. The number of the persons within the image G is detected by counting the number (n) of the areas f1-f4 extracted (B). When the number of the persons in the image G is detected, printing processing is performed by setting the number of the persons as a printing number, so that prints 90 for the number of photographed persons are prepared (C). Also, in the case that a customer orders for additional printing, the printing processing is performed by setting a value obtained by deducting one from the number of the persons in the image G as the printing number, so that the prints 90 of a number which are one print less than the number of the persons are prepared (D).

Title: X ray exposure
Inventor: OKADA KOUICHI
IPC: G03F7/20
Filed: 1980-07-08
Abstract: PURPOSE:To avoid the dependence of a resist on the atmosphere of exposure as much as possible by removing a thin metal film portion except for a required absorbent pattern formed on an X ray mask substrate material. CONSTITUTION:An Au film with a thickness of about 200Angstrom  for plating ground in the portion except for a required pattern portion undergoes a chemical etching and brought into contact with an etching liquid for a short time to eliminate damage to an Au absorbent pattern. A Cr film with a thickness of about 50Angstrom  is necessary for increasing adhesivity between polyimide and the Au film. But it must be removed by a dry etching with a parallel flat plate type reactive sputtering device, when a gas mixture of CCl4 and air is used for the etching gas. The use of the mask thus formed reduces changes in the rate of residual film to a sufficient allowable range for the subsequent process as a negative resist.

Abstract: PURPOSE:To exactly measure a gap of an adjacent rod-like body by arraying plural image guides whose focal distances are different, in one line in the upper and lower parts, and also, turning objective parts of the image guides in the same direction at the same position against its longitudinal direction. CONSTITUTION:A fiberscope (f) is set in advance so as to be turned in the center line direction of a gap b'-a', when an objective part of an image guide (i), a projecting part of a light guide l and the tip part of the fiberscope (f) have been inserted into a position (a) and (b), and its focal distance is set in advance to a-a' or b-b'. In this state, after the end part a' of a rod 6 has appeared in the center line (s), when a moving extent of the fiberscope (f) until the end part b' of a rod 5 appears in the center line (s) is measured, a gap between the rod 5 and the rod 6 can be derived. However, in case a rod 4 is displaced to 4', the end part d'' of the rod 4' shades off and observed. Therefore, when another piece of image guide whose focal distance is d-d' is combined, the end part d'' of the rod 4 can be observed distinctly even in the position (d).
