Filed: 1993-08-05
Abstract: PURPOSE:To effectively remove waveform distortion in the regenerated signal caused by a coma generated by the inclination between an optical disk and an optical head. CONSTITUTION:At the time of the loading of an optical disk 1 when optical information is recorded and reproduced, a region, wherein a specified recording pattern is recorded, is reproduced. The value of the optimum tap coefficient is obtained with an automatic equalizer 5 constituted of a transversal filter having at least three taps. Based on the value, the error signal, which is proportional to a relative inclination B between the surface of the optical disk and an optical head, is obtained. The inclination of the optical head 2 is mechanically adjusted with a circumferential-direction-inclination adjusting mechanism 3 so that the error signal becomes approximately zero. When the recorded data are reproduced, the value of the tap coefficient is finely adjusted in the direction, where the waveform distortion remaining in the reproduced signal is removed, by using the same automatic equalizer 5.

Title: Square cell for liquid sample
Inventor: INABA MASAO
IPC: G01N21/03
Filed: 1982-11-10
Abstract: PURPOSE:To obtain a square cell for a liquid sample by which accuracy can be improved, by forming a protruded part in the middle of each ridge, which is the boundary line of the neighboring inner wall surfaces of the square cell, and suppressing the rise up of the sample by capillarity at the ridge. CONSTITUTION:A square cell has side walls 3, 4, 5 and 6 and a bottom part 7. At the junction part of the neighboring side walls, an inner ridge 2 is formed. In the middle of the ridge 2, a curved part 8, which is protruded inward, is formed. The curved part 8 is formed at the same height of each ridge of four corners. The smaller the square cell, the faster the rising speed of a sample along the ridge. When moisture remains at the ridge, the rising speed of the sample becomes fast. When the square cell is used as a reaction container, a minute amount of sample such as serum is added, and thereafter reagent and diluent are added. When there is no curved part 8, a part of the added sample rises up along the ridges and reaches a part higher than the liquid level when the diluent is added. The finer the amount of the sample, the larger the measuring error. But the ridges are interrupted by the curved parts 8, the capillarity is blocked, and the sample is hard to rise up higher than the curved parts. Therefore, the sample which is not reacted can be eliminated.
