Title: Artificial pupil optical system processing system
Inventor: TAGAWA YOSHIHIKO
IPC: G02F1/13
Filed: 1991-06-20
Abstract: PURPOSE:To speed up the processing of the artificial pupil optical system which simulates the visual system of human beings or animals, to reduce a mechanical driving part, to facilitate miniaturization and automation without being affected by the complexity of an input image, and to attain purpose expansion and reliability improvement by combining optical image processing and digital image processing. CONSTITUTION:An optical image processing system is equipped with three spatial optical modulators (SLM). The SLM1 corresponds to the lens of the eye of the human being and forms images to the incident light with desired focus. The SLM2 corresponds to the retina of the eye of the human being and records inputted image information with a desired sensitive wavelength band. The SLM3 processes a necessary image by Fourier transformation and records it as a diffraction pattern on the SLM3. The image stored in the SLM2 is read out with coherent light from a laser 5 for information processing and the SLM3 is used as a matched filter to perform spatial filtering, thereby identifying the necessary image by a photodetector 8. Its light output is processed finally by a computer 9.

Title: Metal mold for molding synthetic resin lid cap
Inventor: SUZUKI SADAO
IPC: B29L31/56
Filed: 1978-12-01
Abstract: PURPOSE: To prevent shrinkage of molded synthetic resin lid cap and to provide good appearance thereof by avoiding its unbalanced shrinkage after its separation from mould in suck a way that inner face of mould cavity is designed in a specific configuration.  
     CONSTITUTION: Mould cavity 10 is constituted by a space between mould core 20 and outer mould 11 having flat ceiling face 12 of which annular corner has radius R of curvature terminating at its lowest point A. Straight imaginary line l is defined by the point A and the lowermost point B of the outer mould 11. Desired thickness 2 of side wall of completed lid cap is determined by the thickness at the lowest point D of core packing land which extends in parallel with the line l. Thickness of the cavity 10 at the uppermost point of the packing land is designed suck that it is thicker than the desired thickness α by an additional thickness β which is represented by a segment EF extending radially outwardly from the line l and which is determined by the shrinkage coefficient of the thickness α. The inner side face of the outer mould 11 is determined by a curved line between point A and F and a straight line between points F and B, and these lines AF and FB are to be smoothly extended without discontinuty from the ceiling face 12 including corner R. A synthetic resin lid cap molded in the cavity 10 will have its slightly swelled out side surface on its packing land by the additional thickness β when it is separated from the moudls 11 and 20, but it will shrink to the desired thickness 2 with no unbalanced shrinkage as it is cured, resulting in a well molded lid cap with good appearance and no deformation.

A pair of polarization plates 3a, 3b having orthogonally intersecting planes of polarization are provided above and below the butt parts thereof. The fibers 1a, 1b have the distortion of the slow axis in the long axis direction of the elliptical jacket and the distortion of the fast axis in the short axis direction and therefore said parts are observed in bright coloring. Since the elliptical jacket 12 and support 13 differ in refractive index, the light reflects irregularly on the outside of the jacket 12. The operator observes the jacket 12 which appears bold or thin with a microscope 5 and aligns both by rotating adapters 9 thereby matching the intrinsic polarization axes of a pair of the fibers 1a, 1b and connecting the same.

Title: Liquid fuel combustion device
Inventor: ASAKURA RYUJI
IPC: F23D11/40
Filed: 1990-06-07
Abstract: PURPOSE:To enable an easy assemblying of a burner head without breaking the burner head by a method wherein a metallic net is disposed under the burner head, the metallic net is not burned by a combustion flame, the metallic net is not deteriorated, mixing and flow regulating effects of pre-mixed gas are realized to reduce a combustion sound. CONSTITUTION:A metallic net 66 is disposed under a burner head 61. When ignited, a spark 42 flies between an electrode 41 and the metallic net 66 through flame holes 65A by the operation of an igniter 40. Mixture gas D is ignited and then a combustion flame 23 is formed on the burner head 61. The metallic net 66 is disposed under a burner plate 65 and is not burned by the combustion flame 23, so that red heat, cracking and deformation are not generated. Since the mixture gas D is finely divided to flow by the metallic net 66, a flow regulating effect can be attained and at the same time an ignition is carried out at a location where an ignition position with the spark 42 is the nearest to the flame hole 64A or the burner plate 65, i.e., the position were the concentration of the mixture gas D is the highest, so that a positive ignition is assured and an ignition sound generated during the ignition is also reduced.
