Title: Inspecting device for appearances
Inventor: KUJI TOMOHIRO
IPC: G01B15/04
Filed: 1982-05-26
Abstract: PURPOSE:To detect precisely even a very small change in a shape, by comparing the images of adjacent substances to be inspected with each other for inspecting the appearance thereof in the case when the substance having the same shapes are inspected in succession. CONSTITUTION:Two buffer memories 8 and 19 to which electronic line scanning signals are input are provided. Signals from a detector 7 are input alternately to the two buffer memories by a switching circuit 18, and the contents thereof are compared and determined. When patterns 20 having the same shapes are in succession, the images of patterns adjacent to each other, for instance, are input to the buffer memories 8 and 19 and compared. When distance between two patterns compared in this way is several hundreds mum or less, a change in the shape of the image due to the distortion of deflection is almost equal between the two patterns, and thus a part of the change in the shape can be detected by the simple detection of the discord based on the comparison of the shapes.

Abstract: PURPOSE:To fix recording densities in the inner circumference and outer circumference of a disk and to increase a recording capacity by fixing the number of rotation of the disk and making the frequency of information to be recorded higher as a radius position is increased. CONSTITUTION:In the case of recording information, the radius position of a magnetic head 12 on a magnetic disk 11 to be rotated is detected by a scale. A frequency conversion is executed in proportion to the radius so that the recording linear density of the recorded information can be made equal in any radius position, and the information is recorded through a recording and reproducing circuit onto the disk. In the case of reproducing, for an information signal obtained by the head 12, the frequency is inversely converted corresponding to the radius position, in which the head 12 is positioned, through the recording and reproducing circuit, further, an amplitude correction is executed, and thereafter, the signal is taken out as a reproducing signal. Thus, the recording densities in the inner circumference and outer circumference of the disk are fixed, and the recording capacity is increased.

Title: Video signal processing circuit
Inventor: HASHIMOTO JUNJI
IPC: H04N5/21
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain an easy-to-see image even when an electric field strength is suddenly changed by detecting a noise amount for a period of a horizontal synchronizing signal and reading a feedback coefficient based on the detected noise amount used for an address thereby obtaining an accurate feedback coefficient. SOLUTION: The circuit is provided with a horizontal synchronizing signal period noise amount detection circuit 7 to detect an input noise amount from the horizontal synchronizing signal period to apply adaptive control to a feedback coefficient K of a frame cyclic filter based on the noise amount. The circuit 7 samples an input video signal within one horizontal synchronizing signal period to detect a maximum value, a means value of the sampled value, the number of samples in excess of a threshold level of the sampled value, a maximum value, a means value of a change in adjacent samples, and the number of crossings of the distribution of the sampled values with a SYNC tip level of the horizontal synchronizing signal as the noise amount. Thus, the video signal is delayed by one horizontal line at maximum.  A response delay of control of the feedback coefficient is much smaller than that of a conventional circuit and then the noise reduction effect is remarkably improved.

Abstract: PURPOSE: To prepare DNA useful in the biochemical area, easily, by extracting milt of fish without crushing.  
     CONSTITUTION: Milt of fish is extracted directly, without crushing, with a mixture of a concentrated aqueous solution of inorganic salts (e.g. concentrated saline water) and an alkaline solution (e.g. NaOH solution), to obtain deoxyribonucleic acid. Since the milt of fish is mainly composed of cell nucleus, the DNA existing in the nucleus in high concentration can be easily extracted without crushing or grinding the milt. Although the alkali decomposes the DNA to some extent, it is effective to improve the extraction efficiency.

Filed: 1984-05-02
Abstract: PURPOSE:To make it possible to correctly measure the weight and to perform stable heating by supporting a material to be heated, a rotary table and a motor integrally by an elastic member. CONSTITUTION:The weight of a material 23 to be heated is applied to a motor 27 through a rotary table 25, and the material 23 is transferred downwardly in accordance with the weight thereof. The quantity of transfer of the material and the number of vertical vibration of the motor part is detected by a detector 31, and only the weight of the material 23 to be heated can be detected from the weight of the entire part. If the weights of a rotary pan 24, the table 25 and the motor 27 are measured beforehand, it is possible to detect only the weight of the material 23 to be heated. By controlling the operation of the oscillation of a magnetron from this output, it is possible to heat the material for an optimum heating time in accordance with the weight of the material 23 to be heated. A detection coil 36 detects the transfer quantity of a magnet and the number of vibration thereof. The number of vibration of a body is determined depending on the strength of an elastic member supporting the same and the weight of the body. Therefore when the number of vibration is measured, the weight of the body can be obtained.
