Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To efficiently encode and decode information including a nonlinear component. SOLUTION: A blocking circuit 1 divides inputted original image data into prescribed blocks and outputs them to a prefilter circuit 2. The circuit 2 generates a class code in accordance with a pixel pattern of block data that is outputted from the circuit 1 and makes a prefilter coefficient generating circuit 3 generate a prefilter coefficient that corresponds to the class code. And the circuit 2 executes a product-sum operation between the block data and the prefilter coefficient and outputs them to an encoding circuit 4. An additional code generating circuit 5 calculates the difference value between the central pixel and ambient pixels of the block data, generates an additional code by applying a threshold to an acquired difference value and supplies it to the circuit 4. An encoding means adds the additional code to the result of the product-sum operation and outputs it.

Title: Confocal microscope device
Inventor: OTSUKI SHINYA
IPC: G01B11/24
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To process images with a dynamic range above the dynamic range of an AD converter by varying the quantity of measurement light or the signal level of a slice image according to the quantity of reflected light from a sample, weighting the variation quantity, and searching for the slice image. SOLUTION: The photographic signal of a camera 6 has its level controlled by an AGC circuit 21 and is inputted as an NTSC signal to the AD converter 22. When the sample 4 has a steep slope or a small peak, the gain is increased by passing the signal through an AGC circuit 21 to send the NTSC signal which is raised in signal level to the AD converter 22. Gain values of the AGC circuit 21 by frames are sent to the AD converter 23. A CPU 24 while weighting a slice image of the NTSC signal by a gain makes a picture search and displays the image on a CRT 12 through a frame memory 11. The use of the AGC circuit 21 expands the dynamic range and even if the quantity of the reflected light from the sample 4 is small, the picture search can securely be made.

Title: Decantation device and thermal decomposition-infrared spectral analysis method for sample
Inventor: TAKAHASHI YASUO
IPC: G01N21/35
Filed: 1992-12-16
Abstract: PURPOSE:To control the inclination operation of a container with the same amount of precision as manual operation by providing a retention arm and a rotary handle at the center of two large and small discs which are in contact with each other on the circumferential surface. CONSTITUTION:It is desirable that the ratio of diameter of a large disc E to that of a small disc F with extremely different radii of curvature should be 10:1-100:1. The discs E and F are in contact at the side surfaces with each other. Then, when a handle G at the center of the disc F is rotated to rotate the disc F, the disc E with a large diameter than that of the disc F gradually and smoothly rotates. The slow rotary motion is transferred to a container retention tool C which retains a container B being provided at the tip of a retention arm J by the retention arm J. Therefore, the rotation of the handle G causes the container B to be inclined slowly and smoothly and hence a supernatant liquid to flow out quietly and to be separated from a precipitate. Namely, arbitrary rotary control of the handle G enables the container B to be inclined at arbitrary speed and angle and hence achieving the same amount of decantation of a sample as that by manual operation.

Abstract: PROBLEM TO BE SOLVED: To maintain pre-load of a rear bearing even if a main spindle is thermally expanded to displace the position in the axial direction of the rear bearing by inserting the rear bearing in an outer cylinder under the condition in which pre-load is given between the inner/outer rings and the rolling bodies. SOLUTION: By properly correcting and adjusting the thickness of a collar 5b relative to the thickness of a collar 5a, appropriate pre-load is given to a bearing, and because a main spindle is rotatably journaled in a housing, the position in the axial direction of the front part of the main spindle is fixed. When the main spindle is thermally expanded, the rear part, i.e., the outer cylinder of the rear bearing is exclusively displaced in the axial direction together with the rear bearing and the main spindle.  At this time, a rear bearing 7 is fitted to the main spindle in the pressed condition by a rear bearing inner ring pressing nut 17 threadedly engaged with the screw part 9d formed on the rear end part of the main spindle through a collar, similarly a collar 7b is inserted between the outer rings of the rear bearing 7 to be fitted to an outer cylinder 19, and hence pre-load is maintained.
