Title: Optical correlation processor
Inventor: TAKEI TOSHIJI
IPC: G02B27/46
Filed: 1988-09-07
Abstract: PURPOSE:To detect the peak of mutual correlation with an excellent S/N regardless of the relative position of an input image by processing image patterns of the sum of and the difference between two images by Fourier transformation, erasing the peak of autocorrelation between two pieces of image information to be compared, and extracting the peak of mutual correlation. CONSTITUTION:This processor is provided with a means for converting the two pieces of image information to be compared into coherent images, a means 12 such as nonlinear optical crystal which generates a phase conjugate wave, means 3 and 4 for obtaining the image patterns of the sum of and the difference between the two images, lenses 13 and 14 for Fourier transformation, and light receiving means 15 and 16. The intensity patterns of the Fourier-transformed patterns of the sum of and the difference between the two images are shifted optically in phase by 180 deg. from each other with the phase conjugate wave and superposed one over the other, and then further processed by Fourier transformation. Thus, the peak of autocorrelation is erased and only the peak of mutual correlation is detected with the high S/N. Consequently, the position relation between the two images can accurately be recognized regardless of the relative positions of the input images and stable arithmetic operation tolerant to disturbance is enabled.

IPC: D06N3/04
Filed: 1990-08-29
Abstract: PURPOSE: To obtain a stretchable, water-resistant and air permeable laminated structure by allowing the length between adhesion points adjacent in the stretching direction of an elastic fabric when a laminated structure is arranged in a slackened state to correspond to the length of the elastic fabric between the same adhesion points adjacent to the stretching direction of the elastic fabric.

Title: Ceramic heater
Inventor: YAMASHITA YOSHIMI
IPC: H05B3/14
Filed: 1993-09-14
Abstract: PURPOSE:To suppress the costs of a ceramic heater and enhance the yield from production line by structuring the body of the heater so that the area of one-side electrode surface of the heater body is smaller than the area of the counter-electrode surface, and thereby making it possible to adjust the temp. in any desired region(s) and its number. CONSTITUTION:An aluminum metalized film is formed over the whole area of one surface of a heater body made from ceramic 3 to emit heat with current feeding so that an electrode surface 1 is produced, and on the rear surface, electrode surfaces 2a, 2b having smaller area than the electrode surface 1 are formed by an aluminum metalized film. When a switch 8a is put on to impress voltage of a power supply 11 between the electrode surface 1 and one of the small electrode surfaces 2a, only the left portion of a hot plate raises its temperature to perform a partial heat emission. In the case heating takes place only in the right portion, voltage is impressed only between the electrode surface 1 and the other small electrode surface 2b - and in the case heating should take place in the whole area the switch 8a is turned on so that the voltage is impressed both to the small electrode surfaces 2a, 2b. This enables temp. adjustment for any desired regions on the hot plate, and it is no more required to provide heater elements in the number corresponding to the number of the areas to be temp. adjusted.

Title: Color photographic sensitive silver halide material
Inventor: YAMADA KOZABURO
IPC: G03C7/32
Filed: 1984-10-30
Abstract: PURPOSE:To improve the sharpness of a dye image or the color reproducibility by an interlayer effect as well as to control the graininess and gradient by using a specified coupler. CONSTITUTION:This color photographic sensitive silver halide material contains a coupler represented by formula I (where A is a coupler residue capable of separating RED-P by a reaction with the oxidized product of a color developing agent, P is a group cable of eliminating RED by decomposition during development, and RED is a group capable of taking part in an oxidation-reduction reaction with the oxidized product of the color developing agent after separation from P). A compound capturing the oxidized product of a color developing agent (RED, expressed as a scavenger hereunder) is not directly released by a reaction with the oxidized product of the color developing agent. It is separated once from the coupler as a precursor (RED-P) and released into the sensitive material by the decomposition of P. Since P is a group regulating the timing of release of the scavenger, the diffusibility of the scavenger can be controlled.
